CONCEPTUAL FRAMEWORK

THE IMPLEMENTATION OF PUBLIC POLICY: A FRAMEWORK OF ANALYSIS* Paul Sabatier, University of California, Davis Daniel Mazmanian, Pomona College

A common complaint several years ago was that scholars inter- ested in public policy had neglected the implementation of legisla- tive statutes and major court decisions in favor of the antecedent— and supposedly more interesting and problematic—process of policy adoption or the more narrow field of administrative and judicial behavior. But concern over the alleged failure of major legislation in the mid-1960s and early 1970s has led to a rather impressive num- ber of detailed studies of the implementation of specific programs in education,^ urban planning,'^ job creation,^ civil rights,4 environ- mental quality,^ and health services.^ There have also been a number of "thought pieces" and literature reviews which have attempted to bring together some insights from these and other studies. ^

It is now time for a thorough assessment. Further understanding of the policy implementation process requires an integration of the findings and insights of these disparate studies into a reasonably comprehensive conceptual framework which can, in turn, serve as a guide to future research. This paper first briefly examines a number of such efforts noting both their strengths and weaknesses. The bulk of the paper involves an explication of our own proposed frame- work, which is generally niore comprehensive and specific in its identification of variables, particularly with respect to the manner in which statutory characteristics affect subsequent events. It also attempts to capture the dynamic nature of implementation by focusing on the manner in which changes in socio-economic conditions, public opinion, and other factors affect the implementation process. One of our central theses is that many of the case studies which form the bulk of the implementation literature become so immersed in the details of program implementation that they lose sight of the macro-level and political variables which structure the entire process.

*This paper is a truncated and revised version of our mono- graph, "The Implementation of Regulatory Policy: A Framework of Analysis" (Davis, Ca.: Institute of Governmental Affairs, 1979). We would like to thank Nelson Rosenbaum, Mark Nadel, Paul Culhane, Eugene Bardach, Erwin Hargrove, Judy Rosenener, Robert Johnston, Dale Marshall, Lloyd Musolf, Richard Liroff, Daniel Mandelker, Lettie Wenner, Helen Ingram, Karl Kurtz and Paul Berman for their helpful comments on earlier drafts of the paper.

Throughout this paper, we focus primarily on traditional regu- latory policies in which governmental agencies seek to alter the be- havior of private target groups. Nevertheless, we strongly sus- pect that—with a few minor modifications—the framework developed applies also to the following types of policies:

1) Attempts to change the behavior of field-level bureaucrats through legal directives. Examples would include implemen- tation of special-education programs, the Miranda rule, and the National Environmental Policy Act.

2) Attempts to change the behavior of local (and state) officials through attaching conditions to the disbursement of funds. Examples would include implementation of Title I of the Elementary and Secondary Education Act of 1965, as well as the court orders and statutes involving school desegregation.

3) Attempts to change the behavior of private actors through attaching conditions to the disbursement of funds. An exam- ple would be the job creation program examined by Pressman and Wildavsky.

RECENT EFFORTS AT CONCEPTUAL INTEGRATION. To date there have been at least four major efforts to provide some concep- tual integration to the analysis of policy implementation. In one of the first attempts, Martin Rein and Francine Rabinovitz suggested that the implementation process be examined as the working out of three "imperatives:" 1) the respect for legal intent; 2) civil ser- vants' concern for instrumental rationality; and 3) the general expectation that concerted action requires consensus both within the implementing agencies and in their external political system. ^ Paiil Berman focuses on the latter two "imperatives" in his analysis of the implementation stages of federal social programs. He emphasizes the adjustments that programs go through as they wind their way through federal bureaucracies resistant to change and local service delivery organizations which are sensitive to their immediate political environments and to the desires of "street-level" professionals ( e . g . , classroom teachers).^ Eugene Bardach provides a somewhat differ- ent approach by focusing on potential obstacles to the marshalling of the multitude of program elements necessary for the realization of statutory objectives. The unifying metaphor permeating his analysis is that the implementation process should be conceived as a series of games involving the efforts of numerous semiautonomous actors to protect their interests and gain, access to program elements not under their control—all within the face of considerable uncertainty and the context of general expectations that something will be attempted consistent with the legal mandate.^"^ Whereas Bardach and, to a lesser extent, Rein and Rabinovitz view implementation from the standpoint of the strategizing behavior of various actors, Donald Van Meter and Carl Van Horn provide a systems model of the implementa- tion process involving the following factors affecting program per- formance: 1) policy standards and resources (basically funds),

539

2) support for those policies in the political environment, 3) eco- nomic and social conditions, 4) characteristics of the implementing agencies, 5) communication of policy standards and other decisions within and among implementing agencies, 6) incentives to promote compliance with policy decisions, and 7) the policy dispositions of implementing officials.^-^

Collectively, these efforts provide a reasonable overview of policy-making in terms of its complexity and the variety of factors that can either assure or impede successful implementation. But we feel that more is needed. In the first place, more of an effort is needed in conceptualizing and empirically exploring the linkage between individual behavior and the political, economic, and legal context in which it occurs. Second, all of the existing frameworks seriously underestimate the ability of a statute to "structure" the implementation process. While most of them discuss the importance of clear and consistent policy objectives, adequate financial re- sources , and, to a lesser extent, the incentives provided for com- pliance, they neglect the capacity of a statute to determine the num- ber of veto /clearance points, the formal access of various actors to the implementation process, and, to some extent, the probable policy predispositions of implementation officials. Third, none of the avail- able frameworks explicitly addresses what might be termed the "tractability" or solvability of the problem(s) addressed by a public policy. For example, why was it easier to achieve the objectives of the 1966 Voting Rights Act when the implementation of other civil rights laws and court decisions has been so problematic? Fourth, the frameworks of Berman and of Van Meter and Van Horn—the former explicitly, the latter implicitly—apply only to programs which seek to distribute goods and services. This neglects the large number of programs which seek explicitly to regulate the behavior of private actors in, for example, consumer and environmental protection, worker safety, and interstate commerce. Finally, the most compre- hensive framework to date—namely, that of Van Meter and Van Horn —suffers from some of the traditional defects of abstract systems models. Many of the factors in their "model," while useful in ori- enting one's thinking, are essentially amorphous categories rather than variables that can be easily operationalized.^^ In addition, their framework does not identify which variables are controlled by various actors and is, therefore, unlikely to be of much use to policy practitioners.

Despite the limitations of these efforts at conceptualization, each has made important first steps to our understanding of policy imple- mentation, b u r debt to them will be readily apparent throughout the remainder of this paper. At this point, however, our purpose has been to indicate the directions which "second-generation" frameworks should move.

A CONCEPTUAL FRAMEWORK OF THE IMPLEMENTATION PROCESS. Implementation is the carrying out of a basic policy decision, usually made in a statute (although also possible through important execu- tive orders or court decisions). Ideally, that decision identifies the problem(s) to be addressed, stipulates the objective(s) to be pursued, and, in a variety of ways, "structures" the implementation process. In the case of a statute regulating private economic behavior, the

540

implementation process normally runs through a number of stages beginning with passage of the basic statute, followed by the policy outputs (decisions) of the implementing agencies, the compliance of target groups with those decisions, the actual impacts—both intended and unintended—of those outputs, the perceived impacts of agency decisions, and, finally, important revisions (or attempted revisions) in the basic statute.

In our view, the crucial role of implementation analysis is to identify the factors which affect the achievement of statutory objec- tives throughout this entire process. These can be divided into three broad categories: (1) the tractability of the problem(s) being addressed by the statute; (2) the ability of the statute to favorably structure the implementation process; and (3) the net effect of a variety of "political" variables on the balance of support for statu- tory objectives. In the remainder of this section, we shall examine each of the component variables and their potential effects.

The entire framework is presented in very skeletal form in Figure 1. It distinguishes the three categories of (independent) variables from the stages of implementation, which constitute the dependent variables. It should be noted, however, that each of the stages can affect subsequent ones; for example, the degree of tar- get group compliance with the policy decisions of implementing agen- cies certainly affects the actual impacts of those decisions.

Tractability of the Problem(s) Addressed by a Statute. Totally apart from the difficulties universally associated with the implemen- tation of governmental programs, some social problems are much easier to deal with than others. Preserving neighborhood tranquility from noise disturbances in Davis, California, is inherently a far more manageable or tractable problem than the saf'e generation of electrical power from nuclear energy. In the former, unlike the latter, there is a clear understanding of the behavioral changes necessary to re- solve the problem; the behavior to be regulated is not very varied (primarily fraternity parties) and involves only a small subset of the town's population; and the amount of behavioral change required among target groups is quite modest. Discussed below are the number of specific aspects of a social problem which affect the ability of governmental institutions to achieve statutory objectives. While each is a separate variable, they can be aggregated—at least conceptually —into a summary index of (inherent) tractability.^^

H) Difficulties in measuring changes in the seriousness of the problem, in relating such changes back to modifications in the behavior of target groups, and in developing the technology to enable target groups to institute such changes. Any regulatory program assumes that by modifying the behavior of target groups the problem will be ameliorated. For example, reducing sulfur emissions from power plants will reduce the ambient air levels of sulfur dioxide and thereby improve public health. But this implies that ambient air levels can be measured relatively inexpensively and that a causal model exists which relates emissions from specific sources to ambient air levels and, in turn, to health effects on specific subsets of the population.

Moreover, many programs are predicated upon the availa- biUty of technologies without which changes in target group behav- ior will not achieve the desired objectives. For example, reduction in sulfur emissions from power plants is contingent upon finding a reliable and relatively inexpensive technology for removing sulfur from coal either before or after it is used in power generation—with considerable dispute between utilities and the Environmental Protec- tion Agency over whether such a technology is presently available. Other social problems beset by serious technological difficulties include pollution emissions from automobiles, the storage of nuclear wastes, and agricultural pest control.

The absence of a valid causal theory and/or the requisite tech- nology in turn poses a number of difficulties for the successful imple- mentation of statutory objectives. First, any program poses costs to taxpayers (in the form of program administration) and to target groups. To the extent that these costs cannot be justified by mea- surable improvements in the problem being addressed, political sup- port for the program will almost surely decline and thus statutory objectives will be either ignored or modified. Second, disputes over the availability of the requisite technology will produce strong pres- sures for delaying deadlines for achieving statutory objectives and/or considerable uncertainty over the most effective means of encouraging technological innovation—as the very problematic implementation of the "technology-forcing" provisions of the 1970 Federal Clean Air Amendments amply demonstrates.

(2) Diversity of behavior being regulated. The more diverse the behavior being regulated, the more difficult it becomes to frame clear regulations and thus the less likely that statutory objectives will be attained. For example, one of the major obstacles confronting the implementation of the 1972 Federal Water Pollution Control Amendments has been the extreme diversity in the type and seriousness of dis- charges from the nation's estimated 62,000 point sources. Such varia- tion makes the writing of precise overall regulations essentially impos- sible, with the result that regulations for each industry and firm have to be negotiated on an ad hoc basis with considerable discretion left to field personnel.

(3) Percentage of population within a political jurisdiction whose behavior needs to be changed. In general, the smaller and more definable (isolatable) the target group whose behavior needs to be changed, the more likely the mobilization of political support in favor of the program and thus the more probable the achievement of statu- tory objectives. For example, the successful implementation of the 1965 Voting Rights Act derived in large part from the fact that it applied to a fairly specific set of abuses among voting registrars in only seven southern states. This facilitated the formation of a strong constituency in support of the legislation. In contrast, civil rights have been notably less successful when dealing with country- wide problems such as housing discrimination and de facto school segregation.

(4) Extent of behavioral change required of target groups. The amount of behavioral modification required to achieve statutory objec- tives is a function of the (absolute) number of people in the ultimate

543

target groups and the amount of change required of them. The basic hypothesis is, of course, that the greater the amount of behavioral change, the more problematic successful implementation.

In short, some problems are far more tractable than others. Programs which address the former are much more likely to be effec- tive in producing the desired changes in the behavior of target groups and, in turn, in ameliorating the problem being addressed. This brief review of the variables involved suggests that problems are most tractable if (1) there is a valid theory connecting behav- ioral change to problem amelioration; the requisite technology exists; and, measurement of change in the seriousness of the problem is inexpensive (2) there is minimal variation in the behavioral practices which cause the problem; (3) the target group constitutes an easily identifiable minority of the population within a political jurisdiction; and (4) the amount of behavipral change is modest. For example, the success of the 1965 Voting Rights Act in drastically improving the percentage of blacks voting in the South can ultimately be traced largely to the first and third reasons, even though the amount of be- havioral change among Southern voting officials was considerable. In contrast, the implementation of federal occupational health and safety legislation has been exacerbated by the extreme diversity of the practices being regulated, the extensive amount of behavioral change required (particularly in small manufacturing establishments), and, to a lesser extent, problems in actually measuring health and safety benefits.

Nevertheless, one should be cautious not to place too much emphasis on the tractability of the problem being addressed. After all, one of the goals of policy analysis is to develop better tools for addressing heterogeneous problems which demand substantial behavioral change. It is also conceivable that more adequate causal theories, better methods of measurement, and the requisite tech- nologies can be developed. Finally, one of the purposes of our implementation framework is to show how even relatively difficult problems can be ameliorated through a more adequate understanding of the manner in which statutory and political variables affect the mobilization of support necessary to bring about rather substantial behavioral change. It is to an examination of these variables that we now turn.

Extent to Which the Statute Coherently Structures the Implementation Process. From the perspective of our framework, a statute consti- tutes the fundamental policy decision being implemented in that it indicates the problem(s) being addressed and stipulates the objec- tive(s) to be pursued. It also has the capacity to "structure" the entire implementation process through its selection of the imple- menting institutions; through providing legal and financial resources to those institutions; through biasing the probable policy orientations of agency officials; and through regulating the opportunities for par- ticipation by nonagency actors in the implementation process. To the extent that the statute stipulates a set of clear and consistent objectives, incorporates a sound theory relating behavioral change to those objectives, and then structures the implementation process in a fashion conducive to obtaining such behavioral change, the possibi- ties for attaining statutory objectives are enhanced—even if the amount of behavioral change sought in target groups is considerable.

544

(1) Validity of the causal theory underlying statute. Explic- itly or implicitly, a statute implies an underl3ang causal theory: Given a stipulated objective and the assignment of certain rights and responsibilities to various implementing institutions, the target groups will behave in the prescribed fashion and the objective will be attained. Within this theory, however, there are two separate components: "technical validity" and "implementation effective- ness."^-^ The former refers to the relationship between target group behavior and the attainment of statutory objectives—in the case of air pollution control, the relationship between pollutant emis- sions , on the one hand, and the protection of human health and prop- erty on the other.^5 The latter concerns the ability of implementing institutions to produce the requisite behavioral changes in the tar- get groups, preferably with a minimum of adverse side effects. Both components must be valid if statutory objectives are to be attained.

The remaining variables in this section all relate to the "imple- mentation effectiveness" component. At this point we would simply like to underline the point that a sound "technical" component must not only be available but also must be incorporated into a statute if its objectives are to be attained.

(2) Precision and clear ranking of statutory objectives. Statu- tory objectives which are precise and clearly ranked in importance serve as an indispensable aid in program evaluation, as unambiguous directives to implementing officials, and as a resource available to supporters of those objectives.^6 with respect to the last, for exam- ple, implementing officials confronted with objections to their pro- grams can sympathize with the aggrieved party but nevertheless respond that they are only following the legislature's instructions. Clear objectives can also serve as a resource to actors within and external to the implementing institutions who perceive discrepancies between agency outputs and those objectives (particularly if the statute also provides them formal access to the implementation process, e.g. via citizen suit provisions).

While the desirability of unambiguous policy directives within a given statute is normally understood, it is also important that a statute assigned for implementation to an already existing agency clearly indicate the relative priority that the new directives are to play in the totality of the agency's programs. If this is not done, the new directives are likely to undergo considerable delay and be accorded low priority as they struggle for incorporation into the agency's operating procedures. In short, to the extent that a statute provides precise and clearly ranked instructions to implementing officials and other actors—controlling for required departure from the status quo ante—the more likely that the policy outputs of the implementing agencies and ultimately the behavior of target groups will be consistent with those directives.

(3) Financial resources available to the implementing agency. Money is obviously necessary to hire the staff and to conduct the tech- nical analyses involved in the development of regulations, the admin- istration of permit programs, and the monitoring of compliance. More- over, we shall subsequently argue that there are tremendous pressures

545

for regulatory programs to gradually substitute side-payments for police power decisions over time, e . g . , to purchase public easements rather than try to force land developers to provide at their own expense public rights of way to beaches. In general, a threshold level of funding is necessary for there to be any possi- bility of achieving statutory objectives, and the level of funding above this threshold is (up to some saturation point) proportional to the probability of achieving those objectives.^-^

(4) The extent of hierarchical integration within and among implementing institutions. Numerous studies of the implementation of regulatory and social service programs have demonstrated that one of the principal obstacles is the difficulty of obtaining coor- dinated action within any given agency and among the numerous semi-autonomous agencies involved in most implementation efforts. The problem is particularly acute in federal statutes which rely on state and local agencies for carrying out the details of program delivery in a very heterogeneous system. Thus one of the most important attributes of any statute is the extent to which it hierar- chically integrates the implementing agencies. To the extent that the system is only loosely integrated, there will be considerable variation in the degree of behavioral compliance among implementing officials and target groups—as each responds to the incentive for modification within his/her local setting.

The degree of hierarchical integration among implementing agencies is determined by (a) the number of veto/clearance points involved in the attainment of statutory objectives and (b) the extent to which supporters of statutory objectives are provided with induce- ments and sanctions sufficient to assure acquiescence among those with a potential veto. Veto/clearance points involve those occasions in which an actor has the capacity (quite apart from the question of legal authority) to impede the achievement of statutory objectives. ^ ̂ Resistance from specific veto points can, however, be overcome if the statute provides sufficient sanctions and/or inducements to con- vince the actor (whether implementing officials or target groups) to alter their behavior. In short, if these sanctions and inducements are great enough, the number of veto points can delay—but prob- ably never ultimately impede—compliance by target groups. In practice, however, the compliance incentives are usually sufficiently modest that the number of veto/clearance points become extremely important, and thus the most direct route to a statutory objective— e . g . , a negative income tax to provide a minimum income—is normally preferable to complex programs administered by numerous semi- autonomous bureaucracies.

(5) Extent to which decision rules of implementing agencies are supportive of statutory objectives. In addition to providing clear and consistent objectives, few veto points, and adequate incen- tives for compliance, a statute can further bias the implementation process by stipulating the formal decision rules of the implementing agencies.-^^ To the extent, for example, that the burden of proof in permit/licensing cases is placed on the applicant and agency offi- cials are required to make findings fully consistent with statutory objectives, the decisions of implementing agencies are more likely to be consistent with statutory objectives. In addition, a statute can

546

assign authority to make final decisions within implementing insti- tutions to those officials who are most likely to support statutory objectives. Finally, when multi-membered commissions are involved, the statute can stipulate the majority required for specific actions. In the case of regulatory agencies which operate primarily through the granting of permits or licenses, decision rules which make the granting of a permit contingent upon substantial consensus, e.g. a 2/3 majority, are obviously conducive to stringent regulation.

(6) Assignment to implementing agencies/officials committed to statutory objectives. No matter how well a statute structures the formal decision process, the attainment of statutory objectives which seek to significantly modify target group behavior is unlikely unless officials in the implementing agencies are strongly committed to the achievement of those objectives. Any new program requires imple- mentors who are not merely neutral but sufficiently persistent to develop new regulations and standard operating procedures, and to enforce them in the face of resistance from target groups and from public officials reluctant to make the mandated changes.

In principle, there are a number of mechanisms available to statutory framers to reasonably assure that implementing officials have the requisite commitment to statutory objectives. First, the responsibility for implementation can be assigned to agencies whose policy orientation is consistent with the statute and which will accord the new program high priority. 20 This is most likely when a new agency is created specifically to administer the statute, as the pro- gram will necessarily be its highest priority and the creation of new positions opens the door to a vast infusion of statutory supporters. Alternatively, implementation can be assigned to a prestigious existing agency which perceives the new mandate to be compatible with its traditional orientation and is looking for new programs. Second, the statute can often stipulate that top implementing offi- cials be selected from social sectors which generally support the legislation's objectives. For example, several studies of state and regional land use agencies have shown that local elected officials are generally more likely to approve developments than appointees of state officials. ^^ In fact, it is the generally limited practicability of statutes to assign implementation to agency officials committed to its objectives which probably lies behind many cases of suboptimal accomplishment of statutory objectives.

(7) Extent to which opportunities for participation by actors external to the implementing agencies are biased toward supporters of statutory objectives. Just as a statute can bias the implemen- tation process through design characteristics of implementing agen- cies, it can also affect the participation of two groups of actors external to those institutions: a) the potential beneficiaries and target groups of the program and b) the legislative, executive, and judicial sovereigns of the agencies.

In most regulatory programs, for example, the target groups do not have problems with legal standing nor do they generally lack the financial incentives to pursue their case in court if displeased with agency decisions. In contrast, the beneficiaries of most consumer and environmental protection legislation individually do not have a sufficiently direct and salient interest at stake to obtain legal standing

547

and to bear the costs of petitioning adverse agency decisions to judicial and legislative sovereigns. Thus statutes which provide liberal rules of standing for citizen participation as formal inter- venors in agency proceedings and as petitioners in judicial review (in the form of mandamus actions requiring agency officials to comply with statutory provisions) are more likely to have their objectives attained. ^^

Statutes can also affect the scope and the direction of over- sight by agency sovereigns. On the one hand, requirements for formal evaluation studies and provisions which centralize formal legislative oversight in the hands of the statute's chief sponsor te.g., via a select committee of which he/she is chairman) are prob- ably conducive to the achievement of statutory objectives. On the other hand, provisions for legislative veto of administrative regula- tions are probably inimical to the achievement of those objectives simply because the target groups are likely to be much better or- ganized and to have more incentives for appeeiling to legislators than are the beneficiaries of regulation.

In sum, a carefully drafted statute can substantially affect the extent to which its objectives are attained. More precisely, legislation which seeks to significantly change target group behav- ior in order to achieve its objectives is most likely to succeed if 1) it incorporates a valid causal theory linking behavioral change to desired impacts; 2) its objectives are precise and clearly ranked; 3) it provides adequate funds to the implementing agencies; 4) the number of veto points in the implementation process is minimized and sanctions/inducements are provided to overcome resistance; 5) the decision rules of the implementing agencies are biased toward the achievement of statutory objectives; 6) implementation is assigned to agencies which support the legislation's objectives and will give the program high priority; and 7) the provisions for outsider par- ticipation are similarly biased through liberalized rules of standing and by centralizing oversight in the hands of statutory supporters.

Non-Statutory Variables Affecting Implementation, While a statute establishes the basic legal structure in which the politics of imple- mentation take place, implementation also has an inherent dynamism driven by at least two important processes; 1) the need for any pro- gram which seeks to change behavior to receive constant and/or peri- odic infusions of political support if it is to overcome the inertia and delay inherent in seeking cooperation and acquiescence amonp- larp-e numbers of people, many of whom perceive their interests to be ad- versely affected by successful implementation of statutory objectives; and 2) the effect of continuous changes in socio-economic and tech- nological conditions on the reservoir of support for those objectives among the general public, interest groups, and sovereigns. In addition to these changes over time, there is usually enormous varia- tion in crucial independent variables—e.g. the seriousness of the problem being addressed, relevant socio-economic conditions, public opinion—among governmental jurisdictions in which the same statute is being implemented.

The policy outputs of implementing agencies are essentially a function of the interaction between legal structure and political process. Whereas a statute which provides little institutionalized

548

bias leaves implementing officials very dependent upon variations in political support over time and among local settings, a well- drafted statute can provide them with sufficient policy direction and legal resources to withstand short-term changes in public opinion and considerable capacity to bring about the desired behav- ioral changes in widely different local jurisdictions.

This section will discuss the major non-legal variables affecting the policy outputs of implementing agencies, target group compliance with those decisions, and ultimately the achievement of statutory ob- jectives. It will begin with clearly exogenous variables, e . g . , changes in socio-economic conditions; move through essentially inter- vening variables, e.g. attitudes of sovereigns and constituency groups, and deal finally with the variable most directly affecting the policy outputs of implementing agencies, namely the commitment and leadership skill of agency officials.

(1) Variation over time and among governmental jurisdictions in social, economic, and technological conditions affecting the attain- ability of statutory objectives. There are at least four ways in which variation m such conditions over time and among local settings can substantially affect the political support for statutory objectives and, hence, the policy outputs of implementing agencies and even- tually the achievement of statutory objectives.

First, variation in socio-economic conditions can affect percep- tions of the relative importance of the problem addressed by a statute. To the extent that other social problems become relatively more impor- tant over time, political support for allocating scarce resources to the original statute is likely to diminish.^^ Second, successful imple- mentation is rendered more difficult by local variation in socio- economic conditions and, as indicated previously, in the seriousness of the problem being addressed. Such variation produces enormous pressures for "flexible" regulations and considerable administrative discretion to local units. But such discretion increases the probabil- ity of variation in the extent to which the policy outputs of imple- menting agencies are consistent with statutory objectives. On the other hand, the imposition of uniform standards on jurisdictions with widely different situations almost inevitably increases opposition from those who must bear costs which appear unjust. In either case, statutory objectives are less likely to be achieved. Third, support for regulation aimed at environmental or consumer protection or worker safety seems to be correlated with the economic viability of target groups and their relative importance in the total economy. 24 Thus the more diverse an economy and the more prosperous the target groups, the more probable the effective implementation of sta- tutes imposing nonproductive costs on them. The lower the diversity and prosperity, the more likely the substitution of subsidies for police power regulation. Finally, in the case of policies (such as pollution con- trol) which are directly tied to technology, changes or lack of changes in the technological state of the art over time is obviously crucial.

In short, social, economic and technological conditions are some of the principal exogenous variables affecting the policy outputs of implementing agencies and ultimately the attainment of statutory objectives. The primary linkage is through changes in interest group and public support for statutory objectives and/or through

549

the legislative and executive sovereigns of the implementing agen- cies. Alternatively, implementing officials may respond directly (i.e. without any intervening variables) to changes in environmen- tal conditions, particularly if they perceive those changes to be supportive of their programs or preferences.

(2) The amount and continuity of media attention to the problem addressed by a statute. The mass media are important m the imple- mentation process for at least two reasons. First, they are generally a crucial intervening variable between changes in socio-economic conditions and perceptions of those changes by the general public and, to a lesser extent, political elites. This is particularly true for events beyond the local political arena, where most individuals have little direct experience.

Secondly, the tendency for most television stations and news- papers to play an issue to the hilt and then go on to something else is a real obstacle to the constant infusion of political support from the very diffuse beneficiaries of most environmental and consumer protection programs. ̂ 5 This tendency of the media to have a short "issue-attention span" is, in turn, a function of many factors—one of the most important of which is the tendency of most communica- tions organizations to rely on general assignment reporters rather than specialists on specific topics. This suggests that programs which are monitored by specialist reporters will receive above normal media attention over a sustained period of time and—given media support or at least neutrality—are more likely to be effectively implemented. 26

(3) Variations over time and jurisdiction in public support for statutory objectives. The previous discussion has suggested that interest among the general public in a statute or the problem it addresses tends to be cyclical which, in turn, makes it difficult for any program to receive sustained political support. Similarly, variation among political jurisdictions in support for a particular program is likely to result in pressures for ambiguous regulation and considerable discretion to local officials—both of which prob- ably make behavioral change more difficult to achieve.

The general public can influence the implementation process in at least three ways: 1) Public opinion (and its interaction with the mass media) can strongly affect the political agenda, i . e . , the issues to be discussed by legislatures. 2) There is substantial evi- dence that legislators are influenced by their general constituents on issues of salience to those constitutents, particularly when opinion within the district is relatively homogenous.27 3) Finally, public opinion polls are often employed by administrators and sov- ereigns to support particular policy positions. For example, the Environmental Protection Agency sponsored a survey in 1973-74 to refute the conventional wisdom that the Arab oil embargo had sub- stantially undermined public support for pollution control measures; when the poll essentially confirmed the agency's position, it used this information extensively in an effort to convince Congress not to emasculate the 1970 Clean Air Amendments. 2^

Changes in the resources and attitudes of constituency groups toward statutory objectives and the policy outputs of

550

implementing institutions. The basic dilemma confronting pro- ponents of any regulatory program seeking a change in the behavior of one or more target groups is that public support for their position will almost invariable decline over time. Normally, such statutes are the result of very heightened public concern with a general problem such as environmental quality or consumer protection. Such concern soon wanes as the public and the media turn to other issues and as the costs of such programs on specific segments of the population draw away previous supporters and intensify opposition. ^^ The 6^ential—and very problematic—task confronting proponents is to translate the diffuse support which helped pass the initial legisla- tion into viable organizations with sufficient membership, cohesion, and expertise to be accepted as legitimate and necessary partici- pants in important policy decisions by both implementing officials and their legislative/executive sovereigns.

On the other hand, the opponents of the mandated change gen- erally have the resources and incentives to intervene actively in the implementation process. Their organizational resources and access to expertise enable them to make an effective case before administra- tive agencies and, if displeased with their decisions, to initiate appeals to the legislative sovereigns, to the courts, and to public opinion. Because opponents can generally intervene more actively over a longer period of time than proponents, it has long been noted that most regulatory agencies eventually recognize that survival in an unbalanced political environment necessitates some accommodation with the interests of target groups and thus less departure from the status quo than envisaged by the original statutory mandate. ̂ '̂

Constituency groups interact with the other variables in our framework in a number of ways. 31 First, their membership and finan- cial resources are likely to vary with public support for their position and with the amount of behavioral change mandated by statutory ob- jectives. Second, constituency groups can intervene directly in the decisions of the implementing agencies both through commenting on proposed decisions and through supplementing the agency's resources. Finally, such groups have the capacity to affect agency policy indi- rectly through publishing studies critical of the agency's perform- ance, through public opinion campaigns, and through appeals to its legislative and judicial sovereigns.

(5) Continued support for statutory objectives among sover- eigns of implementing institutions via a) amount and direction of~ oversight and b) extent of new (i.e. after original statute) and conflicting legal mandateFi The sovereigns of an implementing agency are those institutions which control its legal and financial resources. They will normally include the legislature (and, more specifically, the relevant policy and fiscal committees); the chief executive; the courts; and, in intergovernmental programs, hier- archically superior agencies.

One of the major difficulties in the implementation of intergo- vernmental programs is that implementing agencies are responsible to different sovereigns who wish to pursue different policies. In such situations, we would suggest that, when an intergovernmental subor- dinate is faced with conflicting directives from its intergovernmental superiors and its coordinate sovereigns, it will ultimately lean toward

551

the directives of the sovereigns who will most affect its legal and financial resources over the longest period of time. For example, when a state agency is faced with conflicting directives from a fed- eral agency and the state legislature, institutional survival requires that it give its primary loyalty to the sovereign most likely to affect its vital resources—which, in almost any conceivable case, will be the state legislature. In relations between a local agency and its state superiors, however, the situation is not nearly so predictable, in large part because local governments generally have less consti- tutional autonomy vis-a-vis states than do the states vis-a-vis the federal government.

These difficulties in intergovernmental programs aside, sov- ereigns can affect the policies pursued by implementing agencies through both informal oversight and formal changes in the agency's legal and financial resources.

Oversight refers to the continuous interaction between an agency and its legislative (and executive) sovereigns in the form of formal oversight hearings, consultation with staff and legislators on the key committees, routine requests from legislators concerning con- stituent complaints, etc. On the one hand, there appear to be rather strong reasons for legislative policy committees to become in- creasingly sympathetic to target groups over time, in part as a re- flection of changes in the balance of interest group support, in part because constituency casework appears to be weighted toward com- plaints . On the other hand, legislative sovereigns supportive of a stringent regulatory program can play a crucial role in the success- ful implementation of such statutes if they have the resources and the desire to do so. Here we come to Eugene Bardach's extremely interesting concept of a "fixer," i.e. an important legislator or execu- tive official who controls resources important to crucial actors and who has the desire and the staff resources to closely monitor the implementation process and to intervene on an almost continuous basis.

On a more formal level, sovereigns have the authority to alter and /or undermine the legal and financial resources of imple- menting agencies. There have, for example been statutes which have been essentially emasculated by the courts or through the appropria- tions process. ^^ Legislatures also have the authority to substantially revise and even revoke statutes; in fact, the first major effort to do so marks the end of what we have termed the short-term implementa- tion process. But the most frequent effects may well be of a more indirect nature. As indicated previously, almost any statute is affected by policies outside its specific domain. Changes in any of these can strongly affect support for statutory objectives and/or the number of veto points involved in statutory implementation. The role of an agency and its legislative supporters is to be aware of these ramifications and to make sure that they are explicitly addressed by (subsequent) legislation. In short, the very interrelatedness of policy areas in any complex society enormously increases the moni- toring responsibility of the protectors of any particular statute and thus the probability that the statute will gradually be undermined through subsequent tangential legislation.

552

(6) Commitment and leadership skill of (supportive) imple- menting officials. We finally come to the variable most directly af- fecting the policy outputs of implementing agencies, namely, the commitment of agency officials to the realization of statutory objec- tives. This comprises at least two components: First, the direction and ranking of the statutory objectives in officials' preference or- derings, and, second, their skill in realizing those preferences i.e. their ability to go beyond what could reasonably be expected in using the available resources. The importance of both attitudes and skill will, of course, vary with the amount of discretion afforded administrators.

The commitment of agency officials will partially—and, in some cases, largely—be a function of the capacity of the statute to institutionalize a bias in the implementing agencies through its selec- tion of institutions and top officials (see p . 547). It will also be a function of professional norms, personal values, and support for statutory objectives among interest groups and sovereigns in the agencies' political environment. In general, the commitment of agency officials to statutory objectives—and the consequent probability of their successful implementation—will be highest in a new agency with high visibility which was created after an intense political campaign. After the initial period, however, the degree of commitment will probably decline over time as the most committed people become burned out and disillusioned with bureaucratic routine, to be r e - placed by officials much more interested in security than in taking risks to attain policy goals. 33

But commitment to statutory objectives will contribute little to their attainment unless accompanied by skill in using available re- sources to that end. Usually discussed under the rubric of "leader- ship," this comprises both political and managerial elements. The former refers to the ability to develop good working relationships with sovereigns in the agency's subsystems, to convince opponents and target groups that they are being treated fairly, to mobilize support among latent supportive constituencies, to adroitly present the agency's case through the mass media, etc. Managerial skill involves developing adequate controls so that the program is not subject to charges of fiscal mismanagement, to maintaining high morale among agency personnel, and to managing internal dissent in such a way that outright opponents are shunted off to noncrucial positions.

On the whole, however, leadership skill remains a rather elusive concept. While everyone acknowledges its importance, its attributes vary from situation to situation and thus it is extremely difficult to predict whether specific individuals will go beyond what could reasonably be expected in using the available resources in support of statutory objectives.

Stages (or Dependent Variables) in the Implementation Process. The discussion thus far has focused on the generic factors affecting the implementation process as a whole. But that process must be viewed in terms of its several stages: (1) the policy outputs (deci- sions) of the implementing agencies; (2) the compliance of target groups with those decisions; (3) the actual impacts of agency deci- sions; (4) the perceived impacts of those decisions; and finally, (5) the political system's evaluation of a statute in terms of major

553

revisions (or attempted revisions) in its content. All of these stages are often lumped together under the rubric of "feedback loop." But one must distinguish two separate processes: If one is concerned only with the extent to which actual impacts conform to statutory objectives, then only the first three stages are perti- nent. In our view, however, one should also consider the political system's summary evaluation of a statute, which necessarily involves the latter two stages as well.

Each of these stages can be thought of as an end point or de- pendent variable. Each is also, however, an input into successive stages. For example, compliance of target groups with the policy decisions of the implementing agencies clearly affects the actual impacts of those decisions. Likewise, the perceived impacts of agency decisions are probably the crucial variable affecting (attempted) revisions in the agency's statutory mandate.

IMPLICATIONS OF THE FRAMEWORK. In order to provide some con- crete examples of the manner in which statutory and political vari- ables interact as the implementation process moves through the stages of the process, two scenarios of implementation are presented in Figures 2 and 3. Figure 2 represents what is usually considered the typical pattern of initial zeal and success followed by a gradual decline. Figure 3 represents the more positive but less frequent pat- tern of continuing success over time. It is assumed in both scenarios that the precondition of a valid causal theory underlies the statute.

As we suggest in the scenarios, successful implementation in the short-run is especially dependent on the strength of the statute, particularly the degree of hierarchical integration, the commitment of agency officials, the presence of a "fixer," and the resources of various constituency groups. In the long-run, however, it is chang- ing socio-economic conditions and the ability of supportive consti- tuency groups to effectively intervene in the process that are probably the most important. To summarize, in terms of a minimum list of crucial conditions, we contend that a statute or other policy decision seeking a substantial departure from the status quo is most likely to achieve its desired goals under the following set of conditions:

1) The enabling legislation or other legal directive mandates policy objectives which are clear and consistent (or at least provides substantive criteria for resolving goal conflicts).

2) The enabling legislation incorporates a sound theory iden- tifying the principal factors and causal linkages affecting policy objectives, as well as the changes in the behavior of target groups (the regulated) and other conditions neces- sary to attain the desired goals.

3) The enabling legislation not only gives implementing agen- cies sufficient jurisdiction over the target groups and other critical areas of intervention but also structures the imple- mentation process so as to maximize the probability that target groups will perform as desired.

The statute clearly mandates significant behavioral change. While the principal implementing agency is given extensive powers, it must work through state and local governments and, moreover, is dependent on private corporations for development of the new tech- nologies necessary to achieve statutory objectives. In short, there are a rather large number of veto points. The lead agency is staffed initially by strong supporters of the statute, but their enthusiasm leads them to "cut corners" in proposing regulations, thereby under- mining the agency's credibility. Moreover, the commitment of agency officials declines as enthusiastic staff wear out and leave, to be replaced by more professional-manageri£tl types anxious to reduce conflict with target groups. Meanwhile, the agency's supportive constituency declines over time, while opposition is vociferous, well- organized, and exacerbated somewhat by a decline in the general economy. Opponents' efforts to emasculate the statute are, how- ever generally thwarted by a very able "fixer" in the short-run. Eventually he dies, and the statute suffers substantial revision, although not total repeal. The statute results in substantial behav- ioral change, although not as much as required in the formal objec- tives. But conformity of the policy outputs of implementing agencies with statutory objectives declines over time—particularly after the death of the fixer—and, thus, there is some erosion in impacts.

This scenario bears some passing resemblance to the (past and and future) implementation of the 1970 Clean Air Act.

Confronted with a rather limited and well-defined set of prob- lems, the proponents of regulation mobilize sufficient public and legislative support to pass a strong statute which establishes a new agency with virtually exclusive jurisdiction over the problem area. The agency is staffed intially by officials strongly committed to its objectives. Backed by strong public and constituency support, they quickly establish policies consistent with those objectives. Target group compliance is high, in part because non-compliance is very visible and in part because agency staff are assisted by supportive constituency groups. After a few years, the original staff leave to go on to more exciting jobs, but the conformity of policy outputs and target group compliance with statutory objec- tives remains high because of the limited nature of the problem, the continued presence of strong public and constituency ^ o u p support, no substantial decline in the local economy, and con- tinued support from local legislators. Because target group com- pliance is directly related to the achievement of statutory objec- tives, the statute continues to have the desired impacts over time.

Contrary to the conventional wisdom concerning the inef- fectiveness of governmental regulation, this scenario is not simply a fair3r tale but instead bears a rather close resemblance to the experience of the San Francisco Bay Conservation and Development Commission.

556

4) The leaders of the implementing agency possess substan- tial managerial and political skill and are committed to statutory goals.

5) The program is actively supported by organized consti- tuency groups and by a few key legislators (or a chief executive) throughout the implementation process, with the courts being neutral or supportive.

6) The relative priority of statutory objectives is not under- mined over time by the emergence of conflicting public policies or by changes in relevant socio-economic conditions which undermine the statute's causal theory or political support.

for example, "political environment." While the amount of support for policy objectives among various actors in the agency's political environment undoubtedly influences agency decisions, one needs to distinguish support among the agency's sov- ereigns (who control its financial and legal resources) from that among organized interest groups, peer agencies, and the general public because each has different resources and pursues different strategies for influencing agency decisions.

"inherent" we mean inherent in the nature of the problem itself, given technical and practical constraints that cannot be removed through hiiman effort (at least not in the short-term) .

•̂ În their analysis of the implementation of the Public Works and Economic Development Act in Oakland, for example. Press- man and Wildavsky argue persuasively that the underlying technical theory that minority employment can be improved through s\ibsidizing capital was simply invalid—or certainly very inefficient—in a generally healthy economy such as Oakland's. A far more valid strategy would have been a direct labor subsidy to businesses which hired minority workers (Pressman and Wildavsky, Implementa- tion, pp. 149-159).

would like to suggest that the clarity and consistency of statutory objectives be conceptualized along the following ordinal scale:

i) Ambiguous objectives. These include both meaningless injunctions to regulate "in the public interest" and man- dates to balance potentially conflicting objectives, e.g. air quality and industrial employment, without establishing priorities among them.

558

ii) Definite "tilt." This involves a relatively clear ranking of potentially conflicting rather general objectives, e.g. "improve air quality even if it results in some unemployment."

iii) Qualitative objectives. These involve a rather precise qualitative mandate to, for example, "protect air quality so as to maintain the public health, including that of susceptible populations." Note that this qualitative objective is considerably more precise than that \inder a "tilt."

iv) Quantitative objectives, e.g. reduce automotive emissions from 1970 levels by 90 percent by December 31, 1975.

Clearly, the last objective constitutes a greater resource to proponents of change than the first.

•^^Determining what constitutes adequate financial resources is, however, extremely difficult, except to note that it must be related to the seriousness of the problem(s) to be addressed (with per capita expenditures often used as a very crude indicator).

calculating the total number of such points, one must sum those involved in the development of general rules and opera- ting procedures, the disposition of specific cases, and the enforcement of those decisions. One must also consider the pos- sibility that implementing agencies are not given adequate legal authority to achieve mandated objectives.

LEGAL STRUCTURING OF IMPLEMENTATION

THE INFLUENCE OF LEGISLATURES AND APPELLATE COURTS OVER THE POLICY IMPLEMENTATION PROCESS Lawrence Baum The Ohio State University

One important question in the study of policy implementation is the capacity of agencies which enact policies to influence the process by which those policies are implemented.^ It is well under- stood that a legislature or a court which adopts a policy lacks com- plete control over the way in which that policy is carried out. But
