CHAPTER 02
THE PROBLEM OF PROVISIONING
2.1 INTRODUCTION
Society is confronted with a finite set of resources and a given state of technology at any given point in time. As a result, there is a finite amount of goods and services that can be produced in that time frame. Given human desires and need for food, clothing and shelter, it is not always possible to produce everything that everyone would like to have. When individuals want more than can be produced they have the economic problem of scarcity.

The problem of scarcity might be resolved by reducing individuals wants or by increasing the output of goods and services. If the solution is to reduce wants, which wants should be eliminated and which should be retained to be satisfied? The individual would necessarily be required to make a choice. If the solution was to produce more goods, which goods should be produced and how are they to be produced? Again, the individual must make choices. In modern, neoclassical, economic analysis (we will call this “orthodox” economics), the problem is structured so the wants are taken as given and the problem is to produce the goods that satisfy the greatest wants.

Scarcity requires that the individual or agent make choices. An individual in isolation (Defoe’s Robinson Crusoe before Friday) would have to make choices since time and resources are limited. It would be necessary to choose whether time was to be spent catching fish, gathering coconuts, reading or building shelter. If the choice were to catch fish, he/she would have to choose between making a net, a fishing pole or trying to catch fish by hand. The choice to spend an hour fishing implies that that hour cannot be used to gather coconuts. The sacrifice of coconuts is called “opportunity cost.”

Even Robinson Crusoe’s world of isolation did not last long. When Friday came to the island, it became necessary to decide who did what and who got what. It is necessary to coordinate the preferences and activities of Crusoe and Friday. Since the story of Robinson Crusoe was written by an Englishman, Daniel Defoe (1659-1731), Crusoe is dominant and he has a greater influence on the decisions than Friday. In 1719, the perspective of an English writer was that aboriginals of various lands were subordinate. Still, it is necessary to coordinate their activities.

2.2 SOCIAL INTERACTION
In a society, the behavior of the individuals must be coordinated through social interaction. This social interaction takes many forms ranging from cooperation to competition. In the process of resolving the allocation problem through social interaction, a set of institutions, organizations, beliefs, principles, perspectives and commonly held values are created. Society, guided by these values, perceptions and beliefs and constrained by institutions, technology and resource endowment, must solve the problem of provisioning. The specific uses of goods and resources must be determined. These choices involve which resources to use, which goods to produce, who will bear the costs and who will benefit.

The basic problem is the coordination of the choices and behavior of individuals. Finding a way to protect the autonomy of the individual while coordinating their behavior to provide for the commonweal has been an important goal of most great writers on social topics.

2.3 SPECIALIZATION
Specialization and the division of labor are two important forms of social interaction that allow two or more individuals to do what an isolated individual cannot do. Both are means to increase the production of goods and services.

Specialization is the case where an individual (firm, organization or country) focuses on the production of a specific good (or group of goods). It can increase the amount of goods that can be produced. It also requires some form of social institution to coordinate the process. If one individual produces food and the other clothing, the two individuals must interact if both are to have food and clothing. This interaction may be facilitated through an institution such as the market or a transfer based on kinship, marriage, religion or government authority. Plato suggests that the city-state is a social construct that is used to facilitate specialization and to improve the welfare of the members of that state.

In The Republic , Plato [427-347 B.C.] suggests specialization as an explanation of the origins of the city-state. Plato describes a conversation between Socrates and a group of students. They are pondering the nature of justice. They conclude that justice is each person doing that which they are best suited to do. The person best suited to be a baker should be a baker: the person best suited to be a shepherd should be a shepherd. Once individuals specialize, the city-state arises to facilitate the transfer of goods and the necessary interactions among the individuals. [ The Republic , Book II] Plato tries to identify the characteristics of the ideal society. One of the focal points is justice that is achieved by “each person doing what they are best suited to do.” Social interaction is required because each person depends on the other members of the community. He devises a meritocracy that is lead by philosopher kings. To prevent nepotism and greed from influencing these philosopher kings, Plato does not allow the philosopher kings to hold private property rights, all of their property is held in common.

2.4 DIVISION OF LABOR
The division of labor is another form of social interaction that allows individuals to do what the isolated person cannot. In the division of labor, the production of a good is broken down into individual steps. One person then performs one step in the process. No single person produces the good alone. The actions of each individual in the production process must be coordinated. In modern industrial societies, production often takes place in a business firm. “Management” is regarded as the process of coordinating the activities of the individuals within the production process. A specific application of microeconomics to the process of production within a firm is called “managerial economics.”

Adam Smith [1723-1790] in the Wealth of Nations proposes that the division of labor is one of the major elements that contribute to economic growth (the increased ability to produce goods and services) [ The Wealth o f Nations, page 1]. The division of labor is the process of dividing a task (work) into its component parts. Smith argues that the division of labor increases production through improved dexterity, saving time in moving from one task to another and improvements in tools.

Smith cautions about the effects of unrestrained use of the division of labor,
“In the progress of the division of labor, the employment of the far greater part of those who live by labor, that is, of the great body of the people, comes to be confined to a few very simple operations, frequently to one or two. But the understandings of the greater part of men are necessarily formed by their ordinary employments. The man whose whole life is spent in performing a few simple operations, of which the effects too are, perhaps, always the same, or very nearly the same, has no occasion to exert his understanding, or to exercise his invention in finding out expedients for removing difficulties which never occur. He naturally loses, therefore, the habit of such exertion, and generally becomes as stupid and ignorant as it is possible for a human creature to become….But in every improved and civilized society this is the state into which the laboring poor, that is the great body of the people must necessarily fall, unless government takes some pains to prevent it.
  [Smith, Wealth of Nations , p 734-735]

Smith, a professor of moral philosophy, constructed a system to explain a set of forces that would guide social and economic behavior. In The Theory of Moral Sentiments [1759] he showed the need for justice and a system of morality. In An Inquiry into the Nature and Causes of the Wealth of Nations [1776] he describes the role of self-interest and markets. In a third book that was destroyed at his request at the time of his death, he describes the need for a system of jurisprudence. Two sets of students’ notes have been used to show these basic arguments in Lectures on Jurisprudence [1762-63 and 1766 published in 1978]. Smith describes a social system that requires morality, markets and jurisprudence to guide and constrain individual action in a social context.

2.5 COORDINATION OF EFFORTS
Once humans use the division of labor and specialization, it is necessary for them to coordinate their efforts. They must interact on a variety of levels. Society is a complex set of interactions among groups and individuals. These interactions give rise to social institutions. The study of these interactions and institutions is “social science.” Human interaction can be studied from a variety of perspectives. Sociology, political science, law, history, psychology, religion, anthropology and economics are examples of social sciences. These are often studied as separate disciplines. However, we should remain aware they are all interrelated perceptions of human behavior. While economics specializes in the study of the processes that coordinate human behavior as it allocates scarce resources to satisfy unlimited wants, its relationship to other social sciences should not be overlooked.

2.6 ECONOMIC ACTIVITIES
John Stuart Mill [1806-1873] divided economic activities into three categories: production, distribution and exchange. It may be helpful to think of an economic system as a process that begins with a set of inputs (or resources) that are used for production that must be distributed for ultimate consumption. (Mill, Principles of Political Economy, The Colonial Press, 1900) The economy is a process of altering a set of inputs to satisfy individual wants. In this example, the steps in the economic process are production, distribution and consumption.

2.6.1 PRODUCTION
Production is the process of altering inputs to increase their ability to satisfy human wants. Inputs are sometime called “factors of production” or resources. Typically, economists will categorize inputs as land, labor and capital. Superficially, labor is defined as human effort used to produce goods that satisfy human wants. An input that is a “gift of nature” is referred to as “land.” Capital is usually considered as an input that is produced by labor but is used for the further production of goods and services. Entrepreneurial ability was the last category of inputs to be added as a factor of production in market oriented economies. It is usually associated with the process of creating and innovating of new processes. The taxonomy of inputs, its relation social structure and the nature of economics will be considered more carefully later in the text.

2.6.2 DISTRIBUTION
Distribution usually describes the process of allocating the goods and services that have been produced. Societies have used market exchange, reciprocity, eminent domain, inheritance, theft and philanthropy to distribute goods and services. The primary means of distribution or allocative mechanisms that are used in most societies are market exchange, reciprocity and eminent domain.

MARKET EXCHANGE
Market exchange involves a quid pro quo, i.e. an exchange of private property rights between individual agents. The terms of the exchange are clearly specified: “I will give you this if you will give me that.” The goods to be exchanged are clearly specified, as are the terms of the exchange.

The participants in the exchange do not need to know each other: they only need to know the terms of the exchange. The information requirements are quite low. In many cases, the exchange may be made easier by social institutions. Laws that protect buyers and sellers may facilitate the exchange. Trust may be an important element as well.
RECIPROCITY
Reciprocity is a system of obligatory gift giving: I will do you a favor or give you a gift, but you are then obligated to do an unspecified favor or give me a gift at some (possibly unspecified) point in the future.

Reciprocity requires a sense of community. Kinship ties or membership in the community is needed so that the obligation of returning a favor is enforced by social forces. If a friend helped you move apartments one weekend and then helped you fix your car the next weekend, your refusal to help that person would have social repercussions. Your common friends might come to regard you as a freeloader. Social pressure may induce you to return the favor.

2.6.2.1 EMINENT DOMAIN
Eminent domain is a redistribution of private property rights through the authority of some organization. The individual is required to give up their claims to private property by an authority. Usually the process of eminent domain is legitimized by government, religion or some other authority.

PHILANTHROPY
The act of giving a gift with nothing expected in return is called philanthropy. This is an important method of distribution in blood drives and the donation of organs for transplantation.

INHERITANCE AND THEFT
Inheritance is the process transferring private property rights from a dead person to an agent. The form that the inheritance laws take may greatly influence the accumulation of wealth in a society.

Theft is the process of transferring property rights by illegitimate force. Few societies can function if theft is widely used.

2.6.3 CONSUMPTION
The end purpose of economic activity is to provide goods and services that can be consumed by individuals to satisfy needs and wants. Modern, neoclassical economists generally do not like to use the word “needs.” The use of the word “wants” is an attempt to take subjective judgment out of the analysis.

2.6.4 COORDINATION, COMPETITION AND COOPERATION
Each society must develop a set of social institutions (behavioural patterns) to coordinate the activities of production, distribution and consumption. There is a wide range of forms these institutions may take depending on the physical environment, state of technical knowledge, social values and other factors. These institutions and behavioral patterns may rely on competition, cooperation or some combination. Market systems tend to focus on competition while other systems may have a larger role for cooperation. A bicycle race is a useful metaphor. In a road race the riders cooperate in the peleton (the large group of riders in a bicycle race) by drafting (using the rider in front to reduce the wind drag). When a group breaks away from the peleton, they typically form a pace line and each shares the work of riding in front of the group. Eventually, the structure of the pace line disintegrates and the riders compete in a sprint to the finish or they fall back into the group. The race is a mixture of cooperation and competition.

Joan Robinson argues that an economic system “… requires a set of rules, an ideology to justify them, and a conscience in the individual which makes him (sic) strive to carry them out.” (Robinson, p 13).

Production, distribution and consumption are interrelated. What to produce is influenced by what individuals want to consume. What people want to consume is influenced by the distribution process and what can potentially can be produced. This coordination may come in the form of cooperative activities, such as the creation of a business firm. The firm usually organizes production internally as a cooperative process but must compete externally. Alternatively, the coordination of activities may be accomplished by competition or some combination of cooperation and competition.

2.7 TECHNOLOGY
Technology is knowledge about how resources, individuals and social organization can be used to accomplish objectives. Technology is more than a set of skills to do things. It is a perspective about the relationships between humans and their world. Technology is the sum total of the ways in which human societies interact with natural and built environments. Humans seek to understand these interactions and develop technology by combining and reorganizing existing technologies.

In economics, technology is the knowledge about the use of scarce resources to produce goods and services that satisfy human wants. The knowledge about how we do things, “technology,” is not limited to machines.

The discovery of a calendar or the realization that crops can be planted on a three field rotation may be as important as the invention of the padded horse collar, the steam engine or the PC. Knowledge about the use of organizational structure to achieve an objective is, in a sense, a form of technology.

The values and structure of society are connected to the state of technology. Society is shaped by technology and at the same time is an important force in the determination of the course of technological change. This relationship between technology, society and the individual can be driven by curiosity and/or material gain.

Technological change is pervasive. During some periods of history, technology changes at a slow pace. At other times, the rate of change is more rapid and more dramatic. During the medieval period, technological change was slow. With the development of mechanical clocks, the plague, moveable type, gunpowder, new techniques in art and other innovations, the “Renaissance” (usually thought of as the 14th-17th centuries) was a period of dramatic change. During the 17th and 18th centuries, the “age of Enlightenment” was fueled by technological change. The “Industrial Revolution” (which is often dated as about 1750) is another term used to identify a period of rapid technological change. Each of these periods involves changes in ideas, values, knowledge and social institutions. Each altered economic and social processes.

There are opposing views as to the process of technological change. One view is the Thomas A. Edison perspective. In this case, technological development is driven by profits. If a technology is profitable, it will be invented. The other view is that technology is a self-generating process. New technology is the result of old technology(ies) being recombined in new ways and used for new purposes. In the second view, profits cannot create the development of technology but determine its uses.

What an individual perceives as a resource is influenced by the nature of technology. In the 18th century, obsidian was an important resource among the inhabitants of the western United States: uranium was not. In the 21st century, obsidian is not normally regarded as a very important resource while uranium has become a resource.

Factor endowment may influence the direction that technology develops. In a society with an abundance or arable land and a shortage of labor may produce (and consume) different goods and seek different technologies to produce them.

In the Edison view, the light bulb was invented because there was a demand for it and it could be developed and produced for a profit. In the second view, it is not possible to invent high-pressure steam engines, even though they may be profitable, until the technology of metallurgy develops metals to contain the higher pressure. Either view supports the argument that technology builds upon itself. The creation of an internal combustion engine depended on its connections to cannons, oil, Maybach’s spray carburetor, levers and gears. Each of these in turn depended on other technologies. When Daimler and Maybach built the automobile, it was the result of a series of connections between technologies that had been developed by many people over a long period. (see Burke, Connections, pp 175-183)

It is useful to think about technological change as a process. First, a piece of knowledge emerges or an “invention” occurs. Second, some one finds an application for the new knowledge (innovation) and uses it. Third is the process of dissemination, i.e. the use of the idea is spread through out the social system.

Each stage of technological change may produce or require significant changes in values and social institutions. Changes in social structure or the natural environment may encourage technological change.

Technology and the social system are interconnected. Technology has a strong influence on the structure of society and individual behavior. The Industrial Revolution may be thought of as a fundamental change in technology of production that altered society. The development of the mechanical clock was driven by the clergy’s desire to satisfy the institution of prayers at specific times of the day.

The perception of and taxonomy of inputs or resources was influenced by social structure. Land was associated with the nobility and the clergy while labor was associated with the serfs. As trade developed, a merchant class arose and became associated with capital.

2.8 ECONOMIC DECISIONS
In a simple taxonomy, individual behavior may be influenced by rules (command), intuition, emotion, habit, reason or some combination. Philosophers and psychologists have struggled with the issue of fate and freewill. The issue has not been resolved. It is not likely that it will be resolved here. The question for economics is to try to understand and explain how humans try to resolve the problems of provisioning and allocation.

2.8.1 RULES
If behavior is constrained or influenced by rules, rules of thumb or habits, the nature of those rules and the process by which the rules evolves is of interest to economists. If the agent’s decision is constrained, the nature of those constraints is of concern.

Rules may by implicit or explicit. Explicit rules often take the form of law and maybe imposed by governments or organizations. Generally, explicit rules are conscious creations and must be communicated and enforced. Social groups may also use explicit rules. Business firms, churches, and other organizations may explicitly impose rules. Implicit rules may also be important constraints. Implicit rules are not consciously created but must still be communicated.

Certain types of behavior are expected and influenced by such social constructs as “manners,” mores, custom, rules of thumb and traditions. These rules are short cuts to problem solving. If over time a particular problem is always or nearly always resolved by a specific approach, that approach becomes a habit or rule of thumb. These rules and habits provide ready made solutions that do not have to be derived by reason or intuition.

2.8.2 INTUITION
In recent years, there has been a growing interest in the interrelationship between psychology and economics. Daniel Kahneman (Nobel Foundation prize winner) has explored intuition and reason as thinking and decision processes. (Kahneman, pp 1449-1475) According to Kahneman, intuition can be powerful and accurate, requires practice and is “ rapid and effortless.” The reasoning process provides a check on the intuitive process.

2.8.3 REASON AND RATIONAL BEHAVIOR
Orthodox, modern economic analysis is generally regarded as the study of alternative uses of resources to achieve objectives. At a technical level, economic analysis is used to evaluate rational decisions. Rational behavior that the agent has identified an objective or goal and has evaluated all feasible alternatives to select the alternative that best achieves the objective.
2.8.4 INFORMATION
Within any economic system, the agents must have information and there must be a set of incentives to encourage appropriate actions. Whether the economic system primarily uses market exchange, reciprocity, eminent domain or some other allocative mechanism, the agents must have information about preferences, inputs, technology and alternatives.

In different economic systems, the decisions may be made by different agents. In a planned economic system, some type of planning authority would necessarily have to have information about the preferences of the members of the systems, all inputs, all technology and all alternatives that are feasible. This is an enormous requirement. In a market-oriented system based on exchange between individual’s, the information requirement is altered. Individuals only need to know about their own preferences and feasible alternatives. What is required is a social system that provides for voluntary exchanges between agents with appropriate information.

In the 1920’s and 30’s there was a debate (The Socialist Calculation Debate) about the ability of socialist systems to acquire necessary information. One side of the debate lead by the Austrians (Ludwig von Mises (1881-1973) and Friedrich Hayek (1899-1992)) argued that it would be impossible for a centrally planned economy run by rules to have the necessary information to function. Oscar Lange (1904-1965) and Abba P. Lerner (1903-1982) argued that if planners were cost minimizers, the appropriate information could be calculated. This is a simplistic description of the Socialist Calculation Debate but emphasizes the importance of information to the functioning of an economic system.

In the Socialist Calculation Debate, Austrians argued that command economies could not be successful because there was insufficient information to guide decisions in the economic process. They believed that each individual had information about their preferences and what they were capable and willing to do. Markets were seen as the social institution that could provide information about relative values through the voluntary, exchange interactions of individuals. The market system was the process that provided the information for the agents to make decisions. The Austrians argued that the command system had no process by which information would be revealed. Lange accepted this criticism and suggested, “market socialism” as an alternative.

Incentives are the forces that encourage or induce agents to behave in particular ways. Duty, authority or self-interest may guide an agent’s behavior. Since neoclassical economics is based on a consequentialist ethic that is expressed through markets, the incentive provided by self-interest is perceived as dominant. Other incentives may be equally as important. Smith believed that self-interest would be constrained by systems of morality and jurisprudence.

2.8.5 RATIONALITY AND INFORMATION
The allocation of scarce resources requires both information and incentives for the agents. Information about the objectives and feasible alternatives is necessary if “rational choices” are to be made. A rational choice requires that the alternative that “best” satisfies the objective be selected. This requires criteria to evaluate each alternative with respect to the objective. Based on the objective, set of alternatives and the method of evaluation, the optimal or best alternative can be selected. There are three fundamental steps to the process of making “rational” economic choices:
· Identify the objective of the agent.
· Identify all feasible alternatives that are related to the objective.

· Develop the criteria to evaluate each feasible alternative with respect to the objective.
