In the last years, research investigating consumer behaviour and how their decision-making

process has advanced and has become an important topic in the marketing society and

literature. To advance the research further, this paper presents an extensive literature review

of academic publications in the area of buying decision-making process in marketing and its

status. Furthermore, the paper presents latest trends and themes that emerge there. Based on

24 journal articles, reports and marketing books, the core models and theories in this area were

evaluated and discussed. Moreover, a framework of "moments that matter" in consumer

decision-making process and factors that influence them was elaborated for a possibility to

influence consumer behaviour in favour of company’s offers. Furthermore, recommendations

for marketers were suggested for deeper understanding the consumer behaviour and their

buying strategies to empower marketing campaigns and be a success in the market. The paper

also suggests several directions for future research related to buying behaviour.

1. Introduction "All marketing decisions are based on assumptions and knowledge of

consumer behaviour."

(Hawkins, Mothersbaugh & Best, 2007)

The consumer behaviour has always been a hot marketing topic, due to

the fact that knowing how and why consumers act in a certain way making

their buying decisions helps companies improve their marketing

strategies and be more successful on the market. Thus, a challenge faced

by all marketers today is how to influence the purchase behaviour of

consumers in favour of their products or services. Therefore, the

knowledge of buying behaviour sheds the light on the psychology of how

consumers think, feel, argument and select among existing alternatives

(e.g., brands, products, and retailers), also how the consumer's

environment (e.g., culture, family, media) influences him/her,

additionally, how consumer motivation and decision strategies distinct

between products. That's all lead to understanding - how marketers can

improve their marketing campaigns to more effectively reach the

consumer.

This research paper focuses on consumer buying behaviour, specifically

on factors/moments that influence customers’ decision-making process.

Research questions are (1) What are the “moments that matter” in

consumer decision-making process? (2) What factors are expected to

influence the “moments that matter” in this process?

The research paper is a literature review of main trends, theories, and gaps

in the field of buyer behaviour. Moreover, a framework of the factors that

influence each step of the decision-making process will be presented and

discussed. At the end recommendations for the further research in this

area will be suggested.

The subject of buying decision-making was chosen due to the several

reasons. First of all, every person is playing a role of a consumer and

makes a lot of purchase decisions every day. It is important to understand

what is influencing personal buying decisions – is it a problem/need or a

well-thought professional marketing campaign. Besides that, from a

marketer perspective, it is valuable to know this topic in order to

effectively target customers, improve products and services of a

company, and understand how customers view products versus

competitors’ products. That is all result in providing value and customer

satisfaction, creating a competitive advantage and enhancing the value of

the company.

Back to XX century scholars were thinking and proposing general

theories and extended frameworks in the sphere of consumer behaviour.

Nowadays, researchers investigate particular determinants and specific

relationships; also more complex questions arise involving other sciences

as, for example, neuroscience. As a result, new fields of science appear,

a good example of this is neuromarketing. Neuromarketing investigates

how human's brain works and reacts to marketing stimuli, applying the

principles of neuroscience to marketing research.

Trends in consumer behaviour also change over years. In a fast-moving

word today people expect things to do not only that involves interacting

with all their senses, but also offer a range of new touch points and what

involves entirely in new experiences. There is an increasing desire for

multiplicity and experiences are expected to offer more. It is no longer

8 Journal of International Business Research and Marketing

enough to immerse the observer in an experience, and people are rejecting

the idea of passive on looking. They desire now active participation.

Multiplicity leads to the need for hyper-efficiency. People are looking for

and finding smarter and more efficient ways to solve their problems.

People are using every last piece of space and time; people are seeking

smart ways to integrate a range of functions into one property.

Additionally, consumers have tasted super-personalization. New

technology means being able to read consumers and give them what they

want – sometimes without even asking them ("Six Trends That Will

Shape Consumer Behavior This Year", 2014). Advanced technologies are

the part of people lives and being constantly online is a status quo, so

happens with buying behaviour, people are switching to e-commerce and

marketers have to take into account.

What is more, nowadays consumers care about the global resources and

community and want to know that the brands they purchase from doing

so too. In 2016 and onwards, it sees more businesses align with

environmental and social causes to appeal to increasing pressure for

brands to authentically stand for something greater than the products they

sell (Walsh, 2016).

Also, today is crucial to take into consideration the characteristics of

current generation – Millennials. They are key social media audience that

isn't easily influenced by social media as 48 percent claim that social

media has never influenced their purchase decisions. Millennials tend to

consume content on various platforms through different devices and are

typically highly influenced by what their peers think. So for marketers, it

is important to understand how this demographic consumes information

and second, how to deliver the right marketing message that appeals to

them (Johson W., 2014).

Marketing has one goal - to reach consumers at the moments that most

influence their decisions when consumers are open to influence, so-called

“moments that matter” or “touch points”. Marketers are always seeking

those moments. For years, touch points have been understood through the

metaphor of a “funnel” (Figure 1).

Figure 1: The Traditional Funnel

Consumers start with some potential brands in mind (left side of the

funnel), then marketing directs them and consumers reduce that number

of brands and move through the funnel, and to the end, they arrive with

the one brand they chose to purchase (right end of the funnel).

But today, the funnel concept fails to capture all the touch points and key

buying factors resulting from the explosion of product choices and digital

channels, coupled with the evolution of an increasingly well-informed

consumer. A more sophisticated approach is required to help marketers

guide through this environment, which is more complicated than the

funnel suggests. McKinsey found that because the communication has

been changed from one-way - marketers to consumers - toward a two-

way communication - marketers to consumers and consumers to

marketers - marketers need a systematic way to satisfy consumer demand

and manage word-of-mouth (Court et al., 2009).

Talking about themes that emerge today, it is important to mention about

creating connections with clients. Understanding the shopping experience

can help companies identify additional consumer-connection moments

before, during, and after the purchase. For instance, when consumers

decided on a purchase, the marketer's work has just begun. A lot of

consumers go online to run further research after the purchase. The post-

sale experience influences their opinion for every subsequent decision, so

it is an ongoing cycle. Besides, understanding the consumer moments

(e.g., the underlying values) provides companies with the opportunity to

make these consumer engagement moments meaningful and memorable.

2. Theory Background

In this chapter of the research paper core theories and models in the field

of consumer behaviour and buying decision-making will be discussed and

evaluated. Different concepts and points of view will be presented by the

scholars of the XX and XXI centuries.

To start with it is necessary to define the term "consumer behaviour".

Business Dictionary offers the following definition. "Consumer buying

behaviour is the process by which individuals search for, select, purchase,

use, and dispose of goods and services, in satisfaction of their needs and

wants". Also in many research articles, authors use the next definition.

"Consumer behaviour is the study of individuals, groups, or organizations

and the processes they use to select, secure, use, and dispose of products,

services, experiences, or ideas to satisfy needs and the impacts that these

processes have on the consumer and society."

Short description

Simon model Simon H.,

1960

This model conceptualises the

decision-making process in

three stages of activities:

intelligence activity, design

activity, and choice activity.

Simon argues that decision-

making is a cognitive process

that can be separated into

simple, sequential steps.

Nicosia model Nicosia F.M.,

1966

This model concentrates on

the communication process

that occurs between a brand

and a consumer. It uses a flow

of events through different

stages that are identified as

fields.

Engel, Kollat &

Blackwell model

Engel J.F.,

Kollat D.T.,

and

Blackwell

R.D., 1968

The components of this

consumer model’s decision

process are the following -

input, information processing,

decision process, and variables

influencing the decision

process. The decision process

component consists of five

9 Journal of International Business Research and Marketing

following stages - need

recognition, search, alternative

evaluation, purchase, and

outcomes.

Theory of buyer

behaviour

Sheth J. &

Howard J.A.,

1969

The theory explains the buyer

behaviour of individuals over

a period. More specifically –

the brand choice behaviour of

the buyer. The authors identify

the elements of consumer

decision process (a set of

motives; several alternative

courses of action, and decision

mediators by which the

motives are matched with the

alternatives), observed the

changes that occur in them

over time as a result of their

repetitive nature and showed

how a combination of decision

elements affects search

processes and the

incorporation of information

from the buyer’s commercial

and social environment. This

model suggests three levels of

consumer decision-making:

extensive problem solving

limited problem solving, and

habitual response behaviour.

An alternative

conceptualization

for consumer

behaviour and

product

performance

Narayana

C.L. &

Markin R.J.,

1975

The authors explain consumer

behaviour by describing the

term “evoked set” by

including and classifying all

the brands that may be in the

consumer’s “awareness set”,

inert, and inept set. They

presented a conceptual

framework for probable

consumer behaviour when

faced with a multiplicity of

brands.

Mintzberg model Mintzberg

H.,

Raisinghani

D. & Theoret

A., 1976

The key premise of this model

is that a basic structure

underlies these “unstructured”

processes.

Keeney’s four-

stage decision-

making model

Keeney R.L.,

1982

This four-stage model takes a

staged approach: Structure the

decision problem (generation

of alternatives and

specification of objectives),

assess possible impacts of

each alternative, determine

preferences (values) of

decision makers, and evaluate

and compare alternatives. This

model depicts the anticipated

complexities at each stage.

Rassuli & Harrell

model

Rassuli K.M.

& Harrell

G.D., 1990

The perspective proposed here

is that choice and purchase can

be viewed as inputs into a

process, not merely the end of

consumer decision-making

efforts. In this way, one

recognizes the feedback, from

choice to other consumer-

behaviour variables.

Sheth, Newman

& Gross model

Sheth J.N.,

Newman B.I.

& Gross

B.L., 1991

This model presents five

consumption values

influencing consumer choice

behaviour: functional, social,

conditional, emotional, and

epistemic values. Any or all of

the five consumption values

may influence the decision.

Smith & Rupp’s

model

Smith A. &

Rupp W.,

2003

This model is an Internet-

based model that takes into

account external influences of

website marketing, the socio-

cultural environment, and

psychological issues on online

consumer tasks which is

followed by to a purchase and

post-purchase behaviour.

The Marketing

Spiral

Armano D.,

2007

Consumer behaviour is like a

spiral that begins with an

interaction as opposed to

communication. The spiral

amplifies as the consumer

increases engagement.

McKinsey’s

dynamic model

of the consumer

decision journey

Court D.,

Elzinga D.,

Mulder S. &

Vetnik O.J.,

2009

This model is more circular

that sequential and has four

primary phases: initial

consideration; active

evaluation, or the process of

researching potential

purchases; closure, when

consumer buy brands; and

post-purchase, when

consumer experience them.

Consumer behaviour is the process consumers experience when they

make purchases, and it involves factors that influence their decision. For

many products and services, purchase decisions are the result of a long,

detailed process that may include a broad information search, brands

comparison, and evaluation. Marketers' success in influencing purchase

behaviour depends to a large extent on how well they understand

consumer behaviour. Marketers need to know the specific needs

customers try to satisfy and how they turn it into purchase attributes. They

need to understand how consumers gather information about different

alternatives and use this information to select among competing brands

(Belch G. & Belch M., 2009).

2.1. Decision-Making Models

One of the most active academic research spheres in marketing over the

past decades has been behavioural decision theory. Behavioural decision

theorists have identified many situations in which consumers make

irrational choices. What all these and other studies emphasise is that

consumer behaviour is very valuable and the context of decisions is really

10 Journal of International Business Research and Marketing

important. Understanding how these effects manifest in the marketplace

can be crucial for marketers. The work of these and other scholars have

also challenged predictions from economic theory and assumptions about

rationality, leading to the appearance of the field of behavioural

economics. In Table 1, the key models are shortly presented starting from

1960 till nowadays.

2.2. Traditional Model of Decision-Making

The traditional model of consumer decision-making process "Five-stage

model of the consumer buying process" (Figure 2) involves five steps that

consumers move through when buying a product or service. A marketer

has to understand these steps to properly move the consumer to the buying

the product, communicate effectively to consumers and close the sale.

Figure 2: Five-stage model of the consumer buying process

For example, Kotler & Keller (2012) in their book describe this model in

details and explain additional stage of the model - disposal stage. Also,

they discuss Moderating effects on consumer decision-making (like

consumer involvement).

Belch G. & Belch M. (2009) went further and discussed relevant internal

psychological processes for each stage of the model (Figure 3)

Figure 3: Internal Psychological Processes

Hereafter for each stage of the model the “moments that matter” and

factors that influence them will be identified and discussed. Moreover, a

self-developed framework about factors and their influences on relevant

moments for consumers will be introduced with the aim of making a

better understanding of the process and how and when it is a good time to

interrupt it with a promotion. Later on, research of other scholars about

factors that affect decision-making will be presented for having a broader

view of the topic.

The very first stage of the model is need/problem recognition when

consumers realize that they need something. Interestingly, marketers

want to create intentionally an imbalance between consumers' present

status and their preferred status. This imbalance will create a need and

make consumers detect and buy a product or service. A need can occur

immediately and can be a very basic impulse - this is called an internal

stimulus. An external stimulus is when a person is affected by outside

influences. Marketers create an imbalance/need by using advertising and

sales promotions. When consumers recognize an unfulfilled need and that

a product will satisfy it, they have created a want.

On this stage for marketers it is important to determine when their target

demographic develops these needs/wants, therefore, it would be an ideal

time to advertise to them. Marketers may also help to recognize the

consumer’s need/problem or circumstances that trigger a need/want.

1 http://study.com/academy/lesson/understanding-the-consumer- decision-making-process-a-marketing-must.html

Moreover, marketers may create the circumstance/need by themselves -

to make the consumer feel insecure without this product or create a

desired status for customers.

Factors that influence these moments are existence/creation of desired

(preferred) status, availability of information about new status (new

products or versions of the products), related/complementary products for

this product may create a need and motives that drive customer.

After the consumer has developed a need/want, he/she starts an

information search about the different alternatives that he/she can

purchase to satisfy the need/want. It is the second stage so-called

information search. He/she will look both internally and externally for

this information to help him/her make a decision. An internal information

search consists of utilizing information from memory, such as past

experiences with the product/service. An external information search is

asking friends and family about their experiences with acquiring a new

product. They can also research public sources, such as reviews, blogs.

Another external information source would be marketing-controlled

sources, such as banners, television ads, brochures, etc. The buying

decision influenced by different sources is presented in Figure 4.

Figure 4: Buying Decision Influence (“Digital Democracy Survey

2015”, 2015)

The amount of time dedicated to this step usually depends on the

consumer's past experience with buying the product, the risk involved and

the level of interest. Once consumer created a set of alternative products

to choose from, he/she has created an evoked set. This set consists of the

most preferred alternatives. Once the evoked set has been decided upon,

the consumer will then conduct final research to further shrink his/her

choices1.

The process of looking for information, in this case, is a moment that

matter for consumers. Marketers have to catch it and provide a relevant

description of the product, promotions, etc. Also, recommendations from

friends and family and reviews from other consumers will be taking into

account. Moreover, previous experience of using the product or similar

one and personal experiments while searching (testing the samples) will

influence the process.

At the third stage of evaluating alternatives, a consumer may ask

her/himself questions like: "Do I actually need the product?" Are there

alternatives out there? Is the original product that bad? Usually, the

consumer chooses one the most important attribute based on which he/she

will make a final decision or using cut-off method (e.g., price, quality,

brand, etc.). Here moments that matter could be emotional

connections/experiences with products, surrender to

advertising/marketing campaigns. For marketers on this step, it is

important that a consumer is aware of their brand during the evaluation

process and ideally knows the attribute based on what the consumer

makes his/her buying decision. The process on this stage is individual for

a consumer as he/she is looking for the best deal. A meaning of the best

deal based on attributes that are more relevant to each consumer, it could

be price, quality, brand, product positioning, a place where to buy

(location), consequences of using the product, etc.

At some point, consumer stops to evaluate evoked set and switches to

buying process – fourth stage: purchase. Once a consumer chooses which

brand to buy, he/she must still implement the decision and make the actual

purchase. Also at the beginning consumer may make a purchase intention

to buy a certain product, but don't close a deal. Additional decisions may

be needed – factors that influence, such as when to buy, where to buy,

and how much money to spend. Often, there is a time delay between the

formation of a purchase decision and the actual purchase, particularly for

complex purchases such as automobiles, personal computers, and

consumer durables. For nondurable products, which include many low-

involvement items such everyday goods; the time between the decision

and the actual purchase may be short. At this point, it is critical to hook

the consumer in purchase intention and a delay period.

On the last fifth stage - post-purchase (satisfaction or dissatisfaction),

consumers evaluate and review the product. Was the product right for the

consumer? Did their expectations confirm? If a customer finds that the

product has matched or exceeded the promises made and their

expectations, they will potentially become a brand ambassador

influencing other potential customers in the stage two of their customer

journey, increasing the chances of the product being purchased again. The

same can be said for negative feedback, which is if emerge at the stage

two can restrain a potential customer's journey towards your product2.

The moments that matter on the last stage is to catch the point if the

customer is not satisfied. If the customer is satisfied, then to turn him/her

into a loyal customer. Such factor as the product matched or exceeded

consumer expectations. Also, follow up activities (after purchase) help to

make a loyal customer.

On Figure 5 the self-developed framework of moments that matter and

factors influence them is presented. One note to this model should be

added. Consumers do not always move in the exact order through the

process. The second and the third stages could be repeated a couple of

times; also the evaluation stage not in all cases finishes with purchase. It

can depend on the type of product, the buying stage of the consumer and

even financial status.

Many of the purchase decisions people make as consumers are based on

a habitual or routine choice process. For many low-priced, frequently

purchased products, the decision process consists of little more than

recognizing the problem, engaging in a quick internal search, and making

the purchase. The consumer spends little or no effort engaging in external

search or alternative evaluation (Belch G. & Belch M., 2009). So not all

of the stages apply to repeated products because the person already has

preferences and brand loyalty and it considers like automatic process.

Therefore, marketers of products characterised by a routine response

purchase process need to get and/or keep their brands in the consumer's

evoked set and avoid anything that may result in their removal from it.

Marketers of these brands want consumers to follow a routine choice

process and continue to purchase their products. This means maintaining

2 http://www.professionalacademy.com/blogs-and-advice/marketing- theories---explaining-the-consumer-decision-making-process

high levels of brand awareness through reminder advertising, periodic

promotions, and prominent shelf positions in stores.

Also, the paper of Hoyer (1984) provides support to statements above and

presents a view of decision-making based on the idea that consumers are

not willing to engage in a big deal of decision-making process at the time

of purchase when they buy a product repeatedly and it is relatively

unimportant. Consequently, consumers apply very quick and effortless

choice tactics that provide a satisfactory decision.

Marketers of new brands or those with a low market share face a different

challenge. They must find ways to disrupt consumers' routine choice

process and get them to consider different alternatives. High levels of

advertising may be used to encourage trial period or brand switching,

along with sales promotion efforts in the form of free samples, special

price offers high-value coupons, etc.

Figure 5: Framework of factors and moments that influence decision-

making

Nonetheless, the traditional model was criticized, and other scholars add

relevant focuses and factors. For example, McAlister (1979) challenged

the existing time assumption that product choices are made separately

from of each other. The scholar offered a model incorporating

dependence among selections of items groups.

Also, Solomon et al. (2006) criticised the traditional model by saying that

it is a rational perspective, but people may behave irrationally "such a

process is not an accurate portrayal of many of our purchase decisions".

Consumers don't go through this sequence whenever they buy something.

The authors talk about purchase momentum (impulses that lead to

unplanned purchase at the last moment). Also, the authors argue that

consumers possess a repertoire of strategies and they choose one

according to the situation and the level of effort required, so-called

constructive processing. Moreover, they discuss behavioural influence

perspective and experimental perspective.

Dhar, Huber & Khan (2007) also talk about shopping momentum that

occurs when an initial purchase provides a psychological impulse that

enhances the purchase of a second, unrelated product. The authors

propose that the most promising theoretical mechanism comes from

Gollwitzer's (1990) theory about implementation and deliberation mind-

sets. Under this theory, shopping momentum occurs because the initial

purchase moves the consumer from a deliberative to an implemental

mindset, thus driving subsequent purchases.

12 Journal of International Business Research and Marketing

2.3 Variations in Consumer Decision-Making

Solomon et al. (2006) characterised the decision-making process as the

amount of effort that goes into the decision each time it must be made.

They found it convenient to think concerning a continuum, which is

started by habitual decision-making and ends with extended problem-

solving (Figure 6). Many decisions are in the middle and characterised by

limited problem-solving.

Figure 6: A continuum of buying decision behaviour

Extended problem-solving phase is similar to tradition decision-making

process described above. Limited problem-solving is usually more

straightforward and simple. People instead use simple decision rules to

choose among alternatives. Habitual decision-making refers to decisions

that are made with little or no conscious effort – to make choices

characterised by automaticity with minimal effort and without conscious

control.

Another researcher Armano (2007) has a different non-linear view of the

decision process, so-called "The Marketing Spiral" (Figure 7). The author

explains it that the spiral amplifies the more the consumer engages, from

interaction to engagement, to participation, to conversation, to affinity, to

a community. The process of the one cycle may repeat itself adding more

cycles to the spiral. But this model did not receive a lot of attention from

other researchers so far.

Figure 7: The Marketing Spiral

McKinsey & Company (2009) supports traditional decision-making

model but showing it as a circular process (Figure 8) with four phases:

initial consideration; active evaluation, or the process of researching

potential purchases; closure, when consumers buy brands; and

postpurchase, when consumers experience them.

Figure 8: Decision-making process

At the end of this section, a couple of other interesting research will be

presented.

A lot of research was done to investigate the how company’s brand

influences buyer behaviour. One of the papers of Macdonald & Sharp

(2000) describes a replication of the study of Hoyer and Brown on “Brand

awareness effects on consumer decision making for a common, repeat

purchase product”. They examined brand awareness in the consumer

choice process. The results of this study support the idea that brand

awareness is a dominant choice tactic among other awareness tactics.

Choosing from different brands consumers show a preference for the high

awareness brand, despite quality and price factors.

Likewise, Heilman, Bowman & Wright (2000) examined how brand

preferences and marketing activities evolve for consumers who are new

to a market. The authors developed a theoretical framework that starts

with a consumer first purchase in a category and shows subsequent

purchases in sequential purchasing stages. The theory is based on the idea

that choices made by new to the market consumers are driven by two

forces. The first is an information collection stage. The second is a stage

in which information collection is extended to less known brands. The

authors use a logit-mixture model with time-varying parameters to

capture the choice dynamics of different consumer segments. The results

of the study show the importance of taking into account a product

experience and learning of consumers new to the market when studying

the dynamics choice processes.

Back to the traditional model, Belch G. & Belch M. (2009) discussed the

difference between low- and high-involvement in decision making. Their

examination of consumer behaviour has looked at the decision-making

process from a cognitive orientation. The five-stage decision process

model views the consumer as a problem solver and information processor

who engages in a variety of mental processes to evaluate various alternatives and determine the degree to which they might satisfy needs

or purchase motives. There are other perspectives regarding how

consumers acquire the knowledge and experience they use in making

purchase decisions. To understand these perspectives, the authors

examine various approaches to learning and their implications for

advertising and promotion. Consumer learning has been defined as “the

process by which individuals acquire the purchase and consumption

knowledge and experience they apply to future related behaviour.” Two

13 Journal of International Business Research and Marketing

basic approaches to learning are the behavioural approach and cognitive

learning theory.

Frequently a distinction is made between high and low involvement

purchasing, that means that in practice the actual buying process can be

less or more reflect this five steps model, depending on the consumer’s

perceived purchasing risks. The high or low degree of involvement is also

an issue of buyer experience. For example, in general, products purchased

for the first time require more involvement than repeatedly purchased

products (Boyd et al., 2002).

Never should forget about relevant external factors that influence

consumer decision-making, such as culture, social class, reference

groups, and situational determinants (Belch G. & Belch M., 2009).

Culture is a one of the complex to study factor. Since there is a change

towards a global market, there are different opinions whether there is a

convergence in consumption patterns. Lifestyles are focusing on the

industrialized world, and similar demographic changes occur in the triad

countries. Paper of Yelkur (2002), for example, compares Generation X

consumers in the US and France on their buyers' behaviour characteristics

such as the importance of brand names, propensity to purchase new

products, and price consciousness. Analysis of the results indicates that

Generation X of different countries has significantly different buyer

behaviour characteristics. The same results may be transmitted to other

countries across the world. Thus there are a lot of unknown issues that

have to be explored.

3. Conclusion

In this research paper, a literature review in the field of consumer

decision-making process was presented, and the papers were discussed

for a deeper understanding of state of the art. For a long time, it was a

"black box" for marketer what happening in a stage between information

search and postpurchase behaviour in buying process. Till now there is

no one right answer, but it is possible to follow the tendencies and shed

light on some processes. Current trends in the field of consumer behaviour

were investigated and presented in the introduction part for catching the

flow of the future changes and challenges.

A lot of academic research was done previously, and various theories and

models were elaborated by the scholars. The traditional model of five-

staged decision process serves as a base for modern concepts as

McKinsey's model (2009). However, it received critics, but nobody can

deny it relevance. Using as a foundation the traditional model a

framework of influences among "moments that matter" in decision-

making and factors was developed and demonstrated. It can help to build

further research on or prove/reject these relationships.

As the report was progressing marketer might find relevant tips and

recommendations for each stage of the new model to use it for a

marketing campaign. That may empower to reach success in the market

and gain loyal customers.

Regarding methodology gaps in reviewed articles, it was noticed that

there should be more sample in the research because nowadays people

demand more and more for personalization and it will help to find out

common characteristics and interrelations. Also, the key topic now is a

difference between generations. How they react on marketing campaigns.

As in this century, at least two generations are presented marketers have

a complex task to please needs and wants both of them using different

approaches.

Moreover, thanks to globalization culture differences are feeling stronger

or less depending on context. However, as previous research proved, in

different countries consumers behave differently. So it means that not all

of the successful marketing instruments in Europe will be so fruitful in

Asia.

Less research was done in the sense of the difference in consumer goods.

More often scholars talk only about durable and nondurable products. But

there is a difference inside these groups of products. Furthermore, less

attention pays to services (not products).

Researchers are also beginning to understand the role of controlling the

information flow about consumers’ decisions, as increased control leads

to increased performance. These new insights promise to be particularly

important in the new online environments, where controlling the

information flow can particularly influence the quality of consumers’

decisions, memory, knowledge, and confidence. Research on information

structure (the amount of information in a choice set) is also relevant in the

new electronic marketplaces, where consumers are regularly faced with

information overload when making decisions.

One more interesting direction of future research would be to investigate

how the shopping momentum effect is moderated by the nature of the

driver item. As a product that considered as “guilty pleasure” (e.g.,

sweets, cigarettes, alcohol, etc.) would be less cause momentum

purchases as standard basket goods, as it is expected.
