This paper examines the role of industry capacity in enforcing collusion in the context of repeated games. For a fixed capacity per firm it is shown that changes in the number of firms have a non-monotone effect on the best enforceable cartel price. This is due to the fact that while an additional firm lowers the share that each of the other firms enjoys at the collusive price it also increases the losses to each firm should the cartel fail.

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.

Certain characteristics of managerial employment arrangements and of the managerial labor market make shareholder wealth dependent on an executive's continued employment. These wealth effects are investigated by examining the common stock price reaction to unexpected deaths of senior corporate executives. Abnormal stock price changes are documented for a sample of fifty-three events. These abnormal stock price changes are associated with the executive's status as a corporate founder and with measures of the executive's ‘talents’ and decision-making responsibility, and of the transaction costs associated with renegotiating or terminating the employment agreement.

This paper investigates the nature of observed deviations from the unbiased expectations hypothesis in the forward foreign exchange market. If these deviations are due to risk premia then the same premia should be observed in nominal bonds denominated in different currencies. This condition imposes testable restrictions on the parameters of a mutivariate regression model. The empirical results are consistent with a world in which time varying risk premia cause the observed deviations from unbiased expectations.
