6 INTRODUCTION TO THE RULES OF THE GAME AND

ECONOMICS SYSTEMS

Whether a society emphasizes the use of exchange, reciprocity or

eminent domain to allocate resources, “Any economic system requires a set of

rules, an ideology to justify them, and a conscience in the individual which

makes him strive to carry them out.” (Robinson, p 13) This set of rules

includes informal institutions and values held by individuals as well as formal

law. The structure of the rules of the games shapes the society’s economic

system. Neoclassical microeconomics does not often explicitly consider the

nature of these rules and their relation to economic behavior.

6.1 ECONOMIC SYSTEMS

Societies that fail to meet minimum subsistence requirements for its

members become relics of the past. Ideally, an economy will produce more

than necessary for subsistence and apply the additional output to improving

the lives of the members of society through development and/or economic

growth. The ideas of “progress,” economic development and economic growth

came with the development of the commercial world that replaced the feudal

society of the medieval world.

An economic system consists of a matrix of social institutions (law, political

institutions, religion, etc), agents (individuals or actors), organizations

(corporations, unions, charitable org, not-for-profit firms, etc) and society. The

principles, beliefs and values held by individuals are included in the structure

of society. The function of an economic system is to coordinate the activities of

agents in the processes of provisioning and allocation. Nonmaterial

106

6.1 Economic Systems

characteristics of life (social stability, low crime rates, a sense of community,

etc) are related to the economic processes and should be included.

Robert Heilbroner identifies thee basic types of economic systems. These

are classified as markets, command, and tradition. In practice, most

economies are a mixture that includes elements of all three. However, the

economic system is usually classified by the dominant approach. Markets and

command exist in traditional economies. Tradition and markets exist in

command economies. Western industrial societies categorized as “market-

oriented” economies rely primarily on exchange, but contain elements of

tradition and command. In market economies tradition is important to such

decisions regarding values, expectations about behavior (trust, loyalty, etc.),

fashion, preferences about housing, choices about occupations and geographic

preferences. Command is also found in market economies as regulations and

laws regarding the allocation or resources and goods.

6.1.1 TRADITIONAL ECONOMIES

Traditional economic systems are based the repeated use of solutions that

have worked in the past. Solutions to problems in the processes of production,

distribution and consumption are embedded in the customs, mores and

cultural patterns of social life. These solutions have been established through

trial and error: those activities that result in adequate production and an

acceptable distribution are retained and used often without question. Agents in

traditional societies may engage in exchange transaction but these are

peripheral to the provisioning and allocation problems.

The traditional economic system tends to be found in non-industrial

societies that are engaged in hunting, gathering, pastoral, or basic agriculture.

Often these are subsistence economies: there is little or no growth or

107

6.1.1 Traditional Economies

progress. The aboriginal culture in Australia is an example of an economy that

has flourished for thousands of years (40,000 years by some estimates) as a

traditional economy.

Traditional economies tend to depend upon a deontological ethic. Duties to

other members of the family, tribe or clan and “reciprocity” are the primary

allocative mechanisms. The forms of production that individuals engage in are

based on the processes that have worked in the past. Social institutions, such

as religion, may evolve to reinforce the traditional ways.

These societies must communicate behavioral expectations to each new

generation. The most important form of knowledge may be contained in

stories and myths. Mythology and story telling are important aspects of the

creation and communication of cultural values. Webster’s Encyclopedic

Unabridged Dictionary of the English Language gives one of the definitions of myth

as:

“an unproved collective belief that is accepted uncritically and is used to

justify a social institution.”

Keen and Valley-Fox describe myths as:

“… an intricate set of interlocking stories, rituals, rites and customs that

inform and give the pivotal sense of meaning and direction to a person,

family, community or culture.” (Keen, p xii)

Mythology is one of the processes by which cultural values and

expectations about behavior are transmitted from generation to generation.

Even in modern societies, stories are fundamental to the process of creating,

and perpetuating culture in societies.

Reciprocity is often a key element in traditional economies. Remember that

reciprocity is based on duty and involves obligatory gift giving: I do you a

favor and both you and I (and other members of society) expect that you will

return some unspecified favor at some unspecified time in the future. It

108

6.1.1 Traditional Economies

requires a sense of duty, social values and a community to enforce

reciprocation. Social institutions give structure to the values, duties and

expectations about economic behavior.

In many societies, reciprocity becomes an important element of the social

process. In a ranching community Rancher Smith goes to the other ranchers

and says: “I need some help branding my calves next Tuesday, I’d appreciate

some help.” On Tuesday, the ranchers show up at Rancher Smith’s place and

help with the task. If Rancher Jones does not come to help, it may be for a

good reason. However, if he or she is perceived as shirking his or her duty, it

may be difficult for Jones to get neighbors to help with future tasks. Similarly,

if everyone helps Rancher Smith but then at some point in the future Rancher

Smith does not reciprocate by helping someone else fix his or her fence, then

Rancher Smith may find it difficult to get anyone to help in the future. There is

a community that expects that the other members will help when needed and

will reciprocate in the future. The community must communicate the

willingness of its members to participate in mutual aid and to sanction

members who do not fulfill their obligatory duties.

Notice that the substance of the event is different if Rancher A says: “I’ll

pay you $10 per hour to help me brand my calves.” Shifting the process from

reciprocity to a market exchange significantly alters the relationships and the

nature of the event. In the case of reciprocity, there is a sense of community.

The relationship between the members of the community may be of value in

and of itself. Blood and organ donations are examples. Moving a good or

activity into a market transaction may significantly alter its meaning or value.

A market exchange can take place between anonymous individuals.

As communities become larger, more complex and social relationships are

altered: tradition may be less useful as an allocative mechanism. It is more

109

6.1.1 Traditional Economies

difficult for the members of the community to communicate the extent to

which the members fulfill their duties. Social pressure to enforce obligations of

reciprocity and duty may become less effective since each person has more

relationships that may be more valued.

Another weakness of a traditional economy is that it does not adapt quickly

to changes in technology or the environment. So long as there are no (or few)

changes in the environment, technology or external forces, the traditional

economy is stable or static. However, if there are sudden changes in the

environment, the traditional solutions may no longer suffice. Droughts,

desertification, over hunting specific animals are examples of events that

traditional societies may not be able to deal with. Native Americans in the

plains developed societies that were dependent upon the bison. Their

economies, social structure, politics and religions were based on bison. With

the advent of Europeans, firearms, railroads and a demand for hides, the

bison were hunted almost to extinction. Many of the native societies found it

difficult to adapt to a system without bison. Whaling, fishing, hunting,

agriculture based on single (or limited) crops are other examples of the

difficulty that traditionally based economies have in adapting to change.

6.1.2 COMMAND ECONOMIES

Eminent domain is the primary allocative mechanism used in a command

economy. An economic system based on command requires an agent or

organization with the authority to make allocation decisions. This authority

may be based on religion, military strength, political position, birth or wealth.

Command economies often rely on traditions as part of the allocative

process. This traditional process is subordinated to eminent domain. The

Roman society is an example of a command economy. Fascist Germany, the

110

6.1.2 Command Economies

former Soviet Union and Maoist China are other examples of attempts to use

command. These economies are often thought of as “planned economies.”

During World War II many allied countries relied on command systems to

coordinate the war effort.

In both traditional and market economies command may play a significant

role. In modern, market economies there are regulations and laws that

mandate particular actions, behavior, production techniques and/or

characteristics of products.

A command economy requires an overall objective or goal for the

governing body: individuals’ goals become subordinate. Since command

economies are often represented by nation states, these can be thought of as

national goals. Some organizations act as small communities with

organizational goals and use command and eminent domain as the primary

allocative mechanism. During the medieval era, the Church and the secular

state both operated as command economies that were interrelated. In the

modern industrial world, the multinational corporation uses a command

system internally: its decisions are made administratively. Goals may include:

economic growth,

full employment,

industrialization,

military strength,

conquest,

acquisition of specie (gold/ silver),

land,

political control

religious conversions

control over markets where they sell,

control of resources,

111

6.1.2 Command Economies

or any thing else that the governing authority chooses.

One of the important questions in a command economy how the overall

objective is selected. It may be an administrative choice. The authority may

simply select the objective. If this is the case, the intentions of the authority

become crucial: are they benevolent or not? In some cases, it may be possible

to have the objectives of the members of the community reflected in the

overall objective. Market socialism in the former Yugoslavia is an example.

The task of the command system is to coordinate individual behavior with

the national or organizational goal. A command system relies on

administrative decisions that flow from the authority down. This requires that

the decisions be communicated to the individuals and enforced. This may

require a complex system of rules and institutions to communicate and create

the appropriate incentives to act on that information.

The authority that is responsible for the administrative decisions that are

imposed on the members of the organization or state, must have information

about the goals, the members of the community, the availability of inputs, all

potential technologies, all alternative outputs and potential distribution

patterns. This is an enormous information requirement that was debated in

the “socialist calculation debate.”

One of the strengths of a command system is that it can alter its objectives

quickly. In a wartime economy, it may be useful to be able to command the

allocation of resources into the development and production of munitions and

military hardware.

The weakness of a command system is that the authority would need an

enormous amount of information about individuals’ preferences and the

production requirements of all goods and services. Command systems may

also be flawed by the nature of the authority that may or may not be

112

6.1.2 Command Economies

benevolent. Another major problem of a command system is the loss of

individual autonomy.

6.1.3 MARKET

Market based economies depend on individual exchange contracts that

occur in the context of a social contract. An exchange contract is based on

quid pro quo, “I will give you this if you give me that! ” The nature of the

goods (include money) to be exchanged as well as the conditions and time is

clearly specified. It is necessary that both parties engage in the contract or

exchange voluntarily.

If the exchange is voluntary, the presumption is that a person would

engage in the exchange if and only if they are better off or no worse off after

the exchange. Therefore, a voluntary exchange results in Pareto

improvements and ultimately a Pareto superior solution to the allocation

problem.

Neoclassical microeconomics uses “supply and demand” as a representation

of a market. The demand function represents the behavioral patterns of the

buyers (both actual and potential) of a specific good. The supply function

represents the behavior of actual and potential sellers (producers) of a good.

The strength of market system is that is capable of quickly adapting to

changes in preferences and technology. The information required by any one

agent is minimal. The weakness is that when exchanges are not voluntary or

property rights are attenuated (weakened), outcomes may be less than

optimal.

Neoclassical microeconomics tends to be a study of contracting and

voluntary exchanges between individuals. The context in which these contracts

113

6.1.3 Market

occur is usually “the market.” The structure of the markets is perceived to

influence the behavior or the individuals who participate in voluntary

exchanges or contracts.

In its most ideal form, the market is characterized as “pure competition.”

In pure competition, there are a large number of buyers and sellers, none of

which can influence the price or the behavior of others: they can only contract

to exchange goods (and money). The purely competitive market is

characterized by goods that are homogeneous: i.e. buyers perceive these

goods as identical or perfect substitutes. Buyers have no preference for one

seller’s good over another’s. The exchange or contract is made on the basis of

price. In this way, sellers compete for buyers by lowering the price to the

minimum they will accept. Buyers compete to purchase by offering the highest

price they are willing to pay. In a market such as this the equilibrium price:

the price at which the last (or marginal) unit is exchanged will optimize the

welfare of the buyers and sellers. In the least desirable market form, a seller

has a monopoly where there is only one seller of a good. The effects of market

structure on the behavior of buyers and sellers are an important topic in

neoclassical microeconomics that is covered in Part II of this text.

The social context of economic behavior is often not made explicit. People

perceive that individual exchange in competitive markets is the only

consideration. This leads to the perception that the government and

community have little or no role in economic activity. Many laissez faire

advocates fail to recognize that economic behavior is a part of social behavior.

Friedrich A. Hayek (1899-1992) is a well-known advocate of the market system.

He identifies the social infrastructure that must exist to support individual

market exchange. The following quotes are long because they are important

and must be considered in the context of Hayek’s ideas:

114

6.1.3 Market

While it would be an exaggeration, it would not be altogether untrue to

say that the interpretation of the fundamental principle of liberalism as

absence of state activity rather than as a policy which deliberately

adopts competition, the market, and prices as its ordering principle and

uses the legal framework enforced by the state in order to make

competition as effective and beneficial as possible-and to supplement it

where, and only where, it cannot be made effective-is as much

responsible for the decline of competition as the active support which

governments have given directly and indirectly to the growth of

monopoly. It is the first general thesis which we shall have to consider

that competition can be made more effective and more beneficient by

certain activities of government than it would be without them. With

regard to some of these activities this has never been denied, although

people speak sometimes as if they had forgotten about them. That a

functioning market presupposes not only prevention of violence and

fraud but the protection of certain rights, such as property, and the

enforcement of contracts, is always taken for granted. Where the

traditional discussion becomes so unsatisfactory is where it is suggested

that, with the recognition of the principles of private property and

freedom of contract, which indeed every liberal must recognize, all the

issues were settled, as if the law of property and contract were given

once and for all in its final and most appropriate form, i.e., in the form

which will make the market economy work at its best. It is only after we

have agreed on these principles that the real problems begin. (Hayek,

pp 110-111)

Hayek continues:

If I am not mistaken, the main headings under which the measures

required to insure an effective competitive order ought to be considered

are the law of property and contract, of corporations and associations,

including, in particular, trade-unions, the problems of how to deal with

those monopolies or quasi-monopolistic positions which would remain in

a otherwise sensibly drawn-up framework, the problems of taxation, and

th problems of international trade, particularly, in our time, of the

relations between free and planned economies.

As far as the great field of the law of property and contract are

concerned, we must, as I have already emphasized, above all be aware

of the error that the formulas of “private property” and “freedom of

contract” solve our problems. They are not adequate answers because

their meaning is ambiguous. Our problems begin when we ask what

ought to be the contents of property rights, what contracts should be

enforceable, and how contracts should be interpreted or, rather, what

standard forms of contract should be read into the informal agreements

of everyday transactions. (Hayek, pp 112-113)

115

6.1.3 Market

Adam Smith also saw a positive role for government. As implied in the

quotes from Hayek, it is the content of the laws of property and contract that

is crucial. It is important to identify the role of the state in structuring the

allocative process that society depends upon.

6.1.4 ROLE OF GOVERNMENT

One of the major controversies is the proper role of government (and the

use of command) within a market based economic system. Many of the issues

in this controversy are ideological in nature and result in the existence of

different “schools of economic thought.” The Chicago School and the Austrian

School of economic thought argue that the role of government in the economy

should be minimized. (Hayek taught at the University of Chicago and was an

Austrian economist.) The American or “Old” Institutionalists and much of

Neoclassical microeconomics (in the Cambridge tradition) sees a more positive

or active role for government in many areas.

The French Physiocrats [led by Francios Quesnay, 1694-1774] advocated a

minimal role for government. Jacques Claude Vincent de Gournay [1712-1759]

is usually credited with the phrase laissez faire, laissez-passer! Some

advocates of an extreme laissez faire doctrine argue that there is no or almost

no role for government. Most argue for limited government action in the

economy. Others, such as Adam Smith and F. A Hayek (above) see a positive

role for social institutions and government participation. Adam Smith [1723-

1790], who was familiar with the work of the Physiocrats, advocated a social

system based on ethics, markets and jurisprudence with a minimal role for

government.

There are many arguments about the proper role of gov
