About this book
This book is the result of a program undertaken nine years ago by the Diebold Institute for Public Policy Studies, Inc., to identify and analyze potentials for private sector involvement in the delivery of public services. Since its founding in 1968, the Diebold Institute has focused on this question in the belief that private enterprise is capable of infusing public service delivery with the efficiency in resource allocation and management that is its hallmark, whether through direct involvement as a service provider or as a source of market dynamics and management techniques.

Public Goods and Public Choices
Vincent Ostrom and Elinor Ostrom Workshop in Political Theory and Policy Analysis, Indiana University
Summary
A new mode of analysis for dealing with the organization and delivery of public goods and services has developed over the last two decades. This mode of analysis, identified with public choice theory, involves the application of economic reasoning to nonmarket decisionmaking. A key element in the analysis turns upon the nature of goods and services. Characteristics which pertain to exclusion and jointness of use can be arrayed to define different types of goods and services. A public good is defined as one which is not subject to exclusion and is subject to jointness in its consumption or use.
Characteristics of nonexclusion and jointness of consumption or use, create situations in which market arrangements may fail to meet individual demands for public goods. Special forms of governmental or quasi-governmental organization are required to deal with these contingencies. The problems, however, occur largely in relation to the organization of collective consumption. As long as appropriate collective consumption units are organized, several alternative options can be used for the production and delivery of public goods and services. These options include private suppliers as well as governmental agencies serving as suppliers.
Where collective consumption is organized apart from production in a public economy, market-like arrangements can exist among producers and collective consumption units. Relations among such units can be conceptualized as forming public service industries in which multiple units coordinate their efforts to supply a particular type of good or service to a community of users. Where competitive pressures are maintained and effective mechanisms for conflict resolution are available, public choice theory suggests that public service industries characterized by multiplicity and overlap, will be more efficient and responsive to user demands than highly integrated governmental monopolies. Public economies that are open to competitive supply of public services by private enterprises are likely to be more efficient than public economies which foreclose such competitive opportunities.
Introduction
Until recently, the private sector and the public sector have been viewed as two mutually exclusive parts of the economy. The private sector is generally viewed as organized through market transactions. The public sector is generally viewed as being organized only through governmental institutions where services are delivered through a system of public administration. Principles of public administration traditionally called for the organization of services through an integrated command structure where all personnel are accountable to a single chief executive. Coordination in the private sector is attained by the market system that governs economic relationships through competitive buying and selling. Coordination in the public sector presumably is attained, by contrast, through a bureaucratic system in which superiors control subordinates in an integrated command structure that holds each public employee accountable to a chief executive as an elective public official.
During the last two decades, traditional presumptions about public sector organization have been subject to serious challenge. Economists studying public sector investment and expenditure decisions have observed that institutions designed to overcome problems of market failure often manifest serious deficiencies of their own. Market failures are not necessarily corrected by recourse to public sector solutions.
This section analyzes the basic characteristics of public services and the important role for diverse organizations, including private enterprises, in the delivery of such services. The public economy need not be an exclusive government monopoly. It can be a mixed economy with substantial private participation in the delivery of public services. Such a possibility offers important prospects for overcoming some public sector inefficiencies and providing taxpayers with an increased return for their tax dollars.
Public economies, however, are quite different from market economies. A private entrepreneur who decides to engage in the delivery of a public service by relying upon traditional market mechanisms is destined to failure. He must instead understand the logic of a public economy and learn to pursue his opportunities within those constraints. The private delivery of public services is a different ball game from the private delivery of private goods and services.
In clarifying the logic of a public economy, we shall first consider the nature of public goods as distinguished from private goods. We shall then explore the organizational possibilities for the public sector, including the development of market-like arrangements. Such arrangements suggest an industry approach to public services with quite different implications for public administration.
The Nature of Public Goods
People have long been aware that the nature of goods has a bearing upon human welfare. Aristotle, for example, observed: "that which is common to the greatest number has the least care bestowed upon it." Within the last two decades an extensive literature has developed on the characteristics that distinguish public or collective goods from private or individual goods. In this discussion we shall consider exclusion and jointness of use or consumption as two essential defining characteristics in distinguishing between private and public goods. We shall also examine basic differences in measurement and degree of choice that have a significant bearing upon the organization of public services. Implications will then be drawn about some inherent problems of organizing economic relationships that involve public goods.
Exclusion
Exclusion has long been identified as a necessary characteristic for goods and services to be supplied under market conditions. Exclusion occurs when potential users can be denied goods or services unless they meet the terms and conditions of the vendor. If both agree, goods or services are supplied at a price. A quid pro quo exchange occurs. The buyer acquires the good and the seller acquires the value specified.
Where exclusion is infeasible, anyone can derive benefits from the good so long as nature or the efforts of others supply it. The air we breathe can be viewed as a good supplied by nature, so exclusion is difficult to attain. A view of a buildingāwhether seen as a "good" or a "bad"āis supplied by the efforts of others and is not subject to exclusion in normal circumstances. Air, noise, and water pollution are "bads" that an individual cannot exclude or avoid except at a cost; conversely, an individual cannot be excluded from receiving a good when the pollution level is reduced.
Jointness of Use or Consumption
Another attribute of goods or services pertains to jointness of use or consumption. No jointness of consumption exists when consumption by one person precludes its use or consumption by another person. In that case consumption is completely subtractible. A loaf of bread consumed by one person is not available for consumption by another; it is subtracted from the total that was originally available. A good having no jointness of consumption and with which exclusion is feasible is defined as a purely private good. Jointness of consumption, on the other hand, implies that the use or enjoyment of a good by one person does not foreclose its use or enjoyment by others; despite its use by one person, it remains available for use by others in undiminished quantity and quality. A weather forecast is an example of a joint consumption good.
Few, if any, joint consumption goods are perfectly non-subtractible. The use and enjoyment of gravity as a force which firmly keeps out feet on the ground may illustrate the case of perfect nonsubtractibility, but most joint consumption goods are instead subject to partial subtractibility. At certain thresholds of supply, one person's use of a good subtracts in part from its use and enjoyment by others. Congestion begins to occur. Each further increase in use impairs the use of the good for each other person in the community of users. Highways, for example, become subject to congestion when the addition of more users causes delays and inconveniences for others. Fire protection, another joint consumption good, may deteriorate when a finite force experiences a high rate of demand. Such goods are then subject to degradation or erosion in their quality unless supply is modified to meet the new demand.
Both exclusion and jointness of consumption are characteristics that vary in degree rather than being all-or-none characteristics. The two extreme cases of jointness of consumptionācomplete subtractibility and complete nonsubtractibilityāgive logical clarity in distinguishing purely private from purely public goods. Whenever use by one user subtracts in part from the use and enjoyment of a good by other users we have partial subtractibility. In the same way we can think of exclusion as applying in degrees. A walled city can attain a high degree of exclusion by controlling admission to those who wish to reside, enter, and do business with the city. Even in the unwalled city, jurisdictional boundaries may be a way for distinguishing between residents and nonresidents where some public goods and services are primarily for the joint benefit of persons living within those boundaries. A weak form of partial exclusion may exist in such circumstances.
Exclusion, and jointness of consumption, are independent attributes. Both characteristics can be arrayed in relation to one another. The jointness characteristic can be arrayed into two classes: alternative uses which are highly subtractible and joint uses which are nonsubtractible. Exclusion can also be arrayed into two classes, in which exclusion is either feasible or infeasible. Exclusion is technically infeasible where no practical technique exists for either packaging a good or controlling access by a potential user. Exclusion may also be economically infeasible where the costs of exclusion are too high. If these defining characteristics are then arrayed in a simple matrix, four logical types of goods are revealed as indicated in figure 1.

Figure 1. Types of Goods
Market arrangements can be used to deliver either private goods or toll goods, that is, where exclusion is feasible. In the case of toll goods a price is charged for access or use but the good is enjoyed in common. Special problems arise, as in a theater, where the conduct of one user may detract from the enjoyment of other users. The value of the good depends both upon the quality of the good produced and upon the way it is used by others.
In the case of a common pool resource, exclusion may be infeasible in the sense that many users cannot be denied access. But, use by any one user precludes use of some fixed quantity of a good by other users. Each pumper in a groundwater basin, for example, makes a use of water which is alternative to its use by each other pumper. Each fish or ton of fish taken by any one fisherman prevents any other fisherman from taking those same fish. Yet no basis exists for excluding fishermen from access to fish in the ocean. Once appropriated from a natural supply, water can be dealt with as a total good to be supplied to those who have access to a distribution system; similarly, once taken from the ocean, fish can be dealt with as a private good. Water management problems, typifying common pool resources, are likely to be subject to market failure while water distribution problems typifying toll goods are likely to manifest market weaknesses associated with monopoly supply.
The broad range of services rendered by governmental agencies may cover all different types of goods and services. The food supplied to school children under surplus commodity programs is an example of purely private goods. Most governmental services, however, are of the public good, toll good, or common pool resource types. These variations may, for example, have significant implications for the development of user charges as substitutes for taxes and other market-like mechanisms in the operation of governmental service activities. In this discussion we shall focus more upon the type characterized as public goods because they pose the more difficult problems in the operation of a public economy.
Before pursuing some of the implications that follow from joint consumption in the absence of exclusion, we shall consider two other characteristics of public goods and services. These relate to measurement and degree of choice. These characteristics also have important implications for the organization and delivery of public services.
Measurement
Since public goods are difficult to package or unitize they are also difficult to measure. Quantitative measures cannot be calculated like bushels of wheat or tons of steel. Qualitative measures such as the amount of dissolved oxygen in water, victimization rates, and traffic delay can be used to measure important characteristics of goods subject to joint consumption, but such measures cannot be aggregated in the same way that gross production can be calculated for a steel factory or for the steel industry as a whole.
The task of measuring performance in the production of public goods will not yield to simple calculations. Performance measurement depends instead upon estimates in which indicators or proxy measures are used as estimates of performance. By utilizing multiple indicators, weak measures of performance can be developed even though direct measures of output are not feasible. Private goods are easier to measure, account for, and relate to cost-accounting procedures and ...
