Copyright University of Chicago Essays in the Theory of Risk-Bearing. By KENNETH J. Chicago: Markham Publishing Co. This volume provides an edited collection of Arrow 1971 essays in the theory of risk-bearing Arrow's many contributions to contemporary analysis in the economics of uncertainty. The 12 essays are all previously published, except that the third essay, "The Theory of Risk Aversion," is a considerably expanded version of earlier published work on the same topic.
Essay 1, "Alternative Approaches to the Theory of Choice in Risk Taking Situations," provides a arrow 1971 essays in the theory of risk-bearing introduction to the problems posed by uncertainty for economic analysis. This includes discussion of probabilistic versus nonprobabilistic, and subjectivist versus relative frequentist views of the treatment of uncertain consequences of decision. A traditional nontechnical treatment of utility theory is provided—beginning with the Bernoulli solution to the Saint Petersburg game and progressing through the von Neumann-Morgenstern-Ramsey utility construction, Wald minimax loss, and Savage minimax regret criteria for the evaluation of uncertain consequences.
The second essay provides an axiomatic approach to choice under uncertainty. The expected utility theorem is proved in an unusual way by exploiting the economic concept of independent goods.
This is achieved by showing that conditional probability distributions over consequences behave like independent goods in ordinary riskless utility theory. Following Ramsey and Savage, it is shown that the axiom of probabilistic beliefs can be derived from other assumptions such as the postulate that preferences among bets are independent of the prizes. They are representative examples of two distinct uses of theory in economic analysis: 1 the use of theory to explain and understand observable economic behavior and institutions, and 2 the use of theory to arrow 1971 essays in the theory of risk-bearing the performance characteristics of non-observed economies and institutions suggested by a reinterpretation of the arguments and equations of a received theory, or by a mathematical formalism.
Thus, essay 3 seeks to give precision to the concept of risk aversion for the purpose of explaining observed aspects of investment, insurance, risk sharing, and liquidity demand behavior.
Essay 4 solves a long-standing intellectual problem in economic theory. The general equilibrium model of the economy is a deep sophisticated treatment of a naive world of certainty, costless information, arrow 1971 essays in the theory of risk-bearing, and costless transactions. Essay 4 removes the certainty stricture on this model by the simple device of re-indexing the commodity space so that cereal is not cereal, but cereal-if-it-rains and cereal-if-it-shines.
This expansion of the ordinary commodity space to a state-contingent commodity space, where states are uncertain, permits the general equilibrium world of certainty and all its results to apply to a general equilibrium world of uncertainty. It is a remarkable commentary on the nature of the human mind that such a contribution and it is indeed should be considered to have solved a problem.
What is not a legitimate use of the state-contingent securities model is to make judgments to the effect that the real world economy is inefficient because there "are not enough markets. The economy must invent claim instruments and institutions that permit risk sharing while economizing on the transactions and information costs of supporting such instruments and institutions. To this end the economy has invented limited-liability legal institutions, common shares, priority debt instruments, options, rights, warrants, multiple-hazard insurance policies, share cropping, oil and gas exploration leases, life insurance policies for key management and research personnel, arrow 1971 essays in the theory of risk-bearing, and so on.
These real-world institutions lead to risk-sharing contracts with the important property that return contingencies depend upon collections of elemental states. Thus, all states that yield a profit provide a proportionate share of such profits to the arrow 1971 essays in the theory of risk-bearing stock holder.
Real world contracts are indivisible packages of Arrow certificates. One must assume that men have invented such packages out of considerations of economy. In these essays. Arrow is concerned to point out some of the limitations inherent in real-world markets for risk shifting.
Thus, in insurance there is the problem of "moral hazard," wherein the purchase of insurance may change incentives and therefore the probabilities upon which the insurance company relies to compute premiums. Unlimited fire or health insurance creates incentives for arson and inessential medical treatment.
Investment in the production of new knowledge tends to be inadequate because of the public good property of information—if I have it, there is not less for you to have. But institutional devices mitigate these limitations. Arrow suggests that coinsurance, whereby the insured pays for a portion of the loss, is an institutional response to the incentive failures resulting from moral hazard.
In medical care, market failure may occur "because medical care belongs to the category of commodities for which the product and the activity of production are identical," so that the consumer cannot test the product before consuming it.
It seems to me that the problem simply stated is that the physician is in the position of deciding what and how much of his services the customer should buy. The preconditions of consumer sovereignty are not present, and the physician is confronted with a conflict of interest that is not subject to the usual market discipline. The same is true of automobile repairing in which the customer cannot usually be assumed to be competent to judge what he should buy. The repairman often decides for him and the complaints are legion.
This has led to a new institution—the diagnostic center, which conducts no repair services, but specializes in the diagnosis of automobile ills. Thus may the customer hope to buy information untainted by the repairman's conflict of interest.
Such an institution, it would seem, might perform a similar function in health care. I have used this book in graduate classes and would recommend it for courses in decision theory, utility theory, and the economics of uncertainty.
