Subjective Prior Probability Distributions and Audit Risk

Journal of Accounting Research 1985 23(1), 37 open access
This paper presents an analysis of the audit risk consequences of PPD ex- tremeness deficiencies and miscalibration.While there is empirical evidence that auditors, like many other decision makers, assess miscalibrated PPDs , the attendant inferential risk consequences of such deficiencies have not been addressed in the extant literature.The comparative statics analysis performed in this study indicates that the risk effects of miscalibration and extremeness deficiencies on the auditor's (substantive testing) evaluation decision are complex and cannot be predicted from an examination of the planning (sampling size) decision.

Existence and Characterization of Perfect Equilibrium in Games of Perfect Information

Econometrica 1985 53(3), 613
[The existence of perfect equilibrium is demonstrated for a class of games with compact space of histories and continuous payoffs, and in which the set of actions feasible at any given period is a lower hemicontinuous correspondence of the previous history of the game. The proof is by construction. A set of histories is constructed, each of which is the equilibrium path of some perfect equilibrium point of the game. Also, any equilibrium path is a member of this set. The construction therefore provides a characterization of perfect equilibrium.]

Voluntary and Efficient Allocations are Walrasian

Econometrica 1985 53(4), 807
Let F be a private ownership economy. Call an allocation w for a price vector p if no agent can benefit by trading less at p. We prove that, under differentiability and interiority, if w is voluntary and Pareto efficient it is a competitive equilibrium for W. Perhaps surprisingly, production economies where some agents receive profit income require a stronger voluntariness condition than the one sufficient for exchange economies. The stronger condition singles out a commodity as a medium of exchange.
