La prise de décision en situation d’incertitude
L'Actualité Economique, 1979, vol. 55, issue 2, 129-150
A conceptual framework is provided by the "states of the world" approach (reviewed in section 1). The powerful normative analysis of individual decision-making under uncertainty extends the theory of consumer choice under certainty into an adequate specification of individual norms of behavior (section 2). But the link with observable market phenomena would require the existence of a complete set of insurance markets, one for every commodity conditionally on every state of the world. Although some disagreement persists on this point, the author feels that the insurance and asset markets which exist in western economies fall substantially short of offering trading opportunities comparable to those implied by a complete set of insurance markets. Consequently, consumer preferences are incompletely revealed by market prices. And business firms lack the information required to reach decisions by mere arithmetic comparisons of alternative profit levels (section 3). Management under uncertainty and incomplete markets acquires genuine significance. What norms of managerial behavior should be assumed for positive economic analysis is a disputed issue. From a normative viewpoint, managerial decisions must be viewed as group decisions, with consequences affecting many individuals—and the theory of such decisions is by necessity more complex (section 4).
