Learning Objectives
Explain the nature of unions and the role they play in the labour market.
Summarize key measures of union influence in Canada
Describe the legal framework governing unions and collective bargaining and how it has evolved.
Use economic models to explain why some workers are more likely to be unionized than others and why unions are more prevalent in some industries, occupations, regions, and countries than in others.
Describe the key factors that determine union objectives and the constraints that unions face in trying to achieve their goals.
Explain and apply economic models that seek to explain how wages and employment are determined in unionized enterprises.

Union Growth and Incidence
Unions
Are collective organizations whose primary objective is to improve the well-being of their members
The objective is met though collective bargaining and the outcome is an agreement specifying:
Wages
Benefits
Aspects of employment relations

Union Growth and Incidence
There are two basic types of unions:
Craft Unions which represent workers in a particular trade or occupation such as printing and construction
Industrial Unions which represent all workers in a particular industry regardless of occupation such as automobile, steel, and forest industries

The Legal Framework
The evolution of the Unions legal framework in Canada
Prior to Confederation the law has discouraged collective bargaining
In the 1870s the law was “neutral” to collective bargaining
In 1944 the law encouraged the spread of collective bargaining

The Legal Framework
Features of Canadian labour relations policy:
Workers have the right to join and form unions
Collective bargaining rights are protected under unfair labour practices legislation
System that defines bargaining representation is successfully established
Union is an exclusive bargaining representative of the workers
The rights are enforced by a labour relations board

Factors Influencing Union Growth and Incidence
The main measures of the extent of unionization:
Union Density which defines the union membership as a percentage of paid workers (about 34% in Canada)
Collective Agreement Coverage which is the percentage of paid workers whose wages and working conditions are covered by a collective agreement (also about 34% in Canada)

Factors Influencing Union Growth and Incidence in Canada
The union is an exclusive bargaining representative for all employees in the bargaining unit
The extent of union organization in Canada varies considerably by industry, occupation, region and various individual employee or employer characteristics
Unionization is highest in nursing and blue-collar occupations
Industry differences are also substantial and public sector employees form unions more often
Full-time workers and workers above 40 are more likely to be unionized

Incidence of Union Organization
Using demand and supply framework
Demand for union representation depends on the expected benefits and costs of union representation
The supply of union representation depends on the contract administration activities from union leaders and staff

Demand for Union Representation
Benefits:
Higher wages
Nonwage benefits
Greater employment security
Protection from arbitrary treatment by management
Costs:
Union dues
Time
Potential loss of income

Supply for Union Represenation
Supply side effects:
Administering contracts (costly)
Reallocation of resources to yield higher return
Organizing new workplace activities (depends on a number of factors)

Factors Influencing Union Growth and Incidence
The extent of unionization depends on choices made by:
Employees
Organizational and Contract Administration activities of union leaders
Actions of the employers
The supply of union organizational and contract administration effort will be high where the per worker cost of organization and representation is low

Empirical Evidence
Riddell, Farber, and later Lipset and Meltz explored the differences in Canadian U.S. unionization rates and discovered that:
The differences in rates can be attributed to differences in supply
The overall desire for unionization is similar in both countries

Empirical Evidence
Factors influencing the demand and supply for unions:
Social attitudes towards unions

Industry and Enterprise Characteristics
Possible causes of higher union concentration in larger firms:
In larger organizations individual action is less effective
Per-worker cost of union organization is lower
Increase in potential gain from unions for the workers

Personal Chracteristics
Less union formation with part-timers
Women are less likely to be represented by a union
Increase in potential gain from unions in blue collar jobs
Decrease in union formation with age
Low paying workers tend to be more interested in union formation

Union Objectives (Simplified)
Utility is a positive function of wage rate and employment
Indifference curve is downward sloping
Higher wage is needed to compensate for lower employment
Curves have a convex shape
Diminishing marginal rate of substitution
23
Union Constraints Demand for Labour
Wage negotiation/market determined employment
Unions negotiate wages taking into account the consequences
The firm decides the employment level
maximizing profits according to DL curve
DL curve is analogous to a budget constraint
Equilibrium is the tangent of the iso-utility curve and DL curve

Union Preferences
Heterogeneous Preferences
Skills
Personal Characteristics such as: age, seniority, etc.
The median voter model does not apply precisely in the union setting since:
Unions do not choose among alternatives by conducting a sequence of pair-wise votes
Most choices are made by union leaders
Union leaders face tradeoffs among several alternatives

32
Union Preferences
Union Leaders versus Union Members
Unions do not make choices in a fully democratic fashion
Leaders are elected to implement policy
Leaders have greater access to information
Union membership and union objective
Changes to membership alter union preferences
In rapidly expanding firm median voter theorem will fail

Union Constraints
Union must negotiate with the firm
Union must take into account the consequences of its decisions
The firm chooses employment level where profits are maximized

34
Union Constraints
Firm’s Isoprofit Curves
The curves are combinations of wage rates and employment rates that yield equal profits
Lower curves imply higher profits
Maximum is attained where the isoprofit and labour curves intersect at the maximum of isoprofit curve
With increasing employment, profit must decrease for a given wage rate
With higher wage profit falls for a given employment

Firm’s Isoprofit Curves
Isoprofit curves are upward sloping to the left of the labour demand curve,
are downward sloping to the right, and attain a maximum at the intersection with the
labour demand curve.

Firm cannot pay wages below alternative wage (Wa)
Firm prefers If and union Iu
Bargaining range in the interval WaWu
Wage rate will lie in the bargaining range
With level of employment determined by labour demand function
38
Relaxing the Demand Constraint
Unions can alter the set of available options by altering the following constraints:
Making the demand for labour more inelastic
Alter the constraint of product market by supporting the quotas, tariffs, etc.
Opposition to regulations
Policies that focus on labour demand such as minimum wage laws or full employment policies
Limiting immigration

Efficient Wage and Employment Contracts
The parties are better off in the shaded areas
A’’ is Pareto-efficient outcome
The outcome is where union indifference curve is tangent to the firm’s isoprofit curve
The locus of Pareto-efficient wage employment outcome is called the contract curve which is CC’
The contract curve must lie to the right of the labour demand curve
Moving up on the CC: unions are better off
Moving down on the CC: the firm is better off

Efficient Wage and Employment Contracts
Obstacles to Reaching Efficient Contracts
Information needed may not be available
An agreement about employment difficult to enforce
Changes in the market and economic conditions or the employers’ financial viability.
Monitoring and enforcing efficient contracts are too costly in most settings

Efficient Wage and Employment Contracts
Efficient versus Inefficient Contracts
Two main models discussed:
Labour Demand Curve Model: Involves two parties negotiating the wage rate and the firm setting the employment
Efficient Contracts Model: Involves two parties negotiating on both the wage rate and the employment

Because of the obstacles explained, the firm and the union agree to set of approximately efficient contracts denoted by DC
L
45
Empirical Application
Union has a dominant power and can determine the wage
Union places high weight on employment
Union’s preferences display diminishing marginal rate of substitution
Union preferences are sensitive to alternative wage

46
Union Bargaining Power
Assuming that the two parties negotiate over wages alone
Union bargaining power related to the elasticity of labour demand:
The more inelastic, the more power to raise the wage rates
Union bargaining power associated with the ability to raise wages
Related to both the labour demand elasticity and the costs of disagreement to each party

48
Alternative Aspects of Union Power
The union is willing to raise wages substantially because the demand for labour is relatively inelastic.
The union is not willing to raise wages substantially because the demand for labour is highly elastic.
48
Union Power and Labour Supply
Strike threat is the primary source of bargaining power
Restricting Supply: Craft Unions
Can raise wages artificially
Controlling entry to their craft
Try to control the whole trade
Set productivity related factors artificially high
Restricting Supply: Professional Associations
Have control over the process of occupational licensing and certification
The supply of labour to the occupation is restricted
The outcome is higher wage but lengthy education periods
