Foundations of Dominant-Strategy Mechanisms

Robert Wilson criticizes applied game theory's reliance on common-knowledge assumptions. In reaction to Wilson's critique, the recent literature of mechanism design has adopted the goal of finding detail-free mechanisms in order to eliminate this reliance. In practice this has meant restricting attention to simple mechanisms such as dominant-strategy mechanisms. However, there has been little theoretical foundation for this approach. In particular it is not clear the search for an optimal mechanism that does not rely on common-knowledge assumption would lead to simpler mechanisms rather than more complicated ones. This paper tries to fill the void. In the context of an expected revenue maximizing auctioneer, we investigate some foundations for using simple, dominant-strategy auctions.     

The Interdependent Use of Earnings and Dividends in Financial Analysts' Earnings Forecasts*

Abstract. This paper examines how analysts combine earnings and dividend information when they predict future earnings. Because both earnings and dividends are noisy indications of future earnings, we posit that analysts use the two corroboratively, to confirm the information reflected in each, and that analysts will substitute away from earnings when it is noisy and toward dividends. Using regressions of analysts' earnings forecast revisions on unexpected earnings, unexpected dividends, and five variables that reflect whether the signs of unexpected earnings and dividends confirm or contradict each other, we find evidence of both corroboration and substitution. Analysts' earnings forecast revisions are significantly related to the five corroborative variables, and this relation has statistically significant explanatory power beyond that in the magnitudes of unexpected earnings and unexpected dividends. Consistent with expectations, we find that the evidence of corroboration varies across the noisiness of earnings information; there is more evidence of corroboration when earnings are more variable. We also find evidence consistent with analysts substituting away from earnings, toward dividend information for firms with noisy earnings information (high variance). Overall, the results imply that analysts use earnings and dividend information interdependently, with some interdependency determined by the noisiness of earnings announcements. Résumé. Les auteurs examinent comment les analystes combinent l'information relative aux bénéfices et aux dividendes pour prévoir les bénéfices futurs. Les bénéfices et les dividendes étant tous deux des indicateurs imparfaits des bénéfices futurs, les auteurs posent l'hypothèse que les analystes utilisent les deux, à titre corroboratif, pour confirmer l'information que livre chacun de ces indicateurs et qu'ils préféreront les dividendes aux bénéfices, si ces derniers se révèlent un indicateur imparfait. En procédant à la régression des révisions des prévisions de bénéfices des analystes sur les bénéfices imprévus, sur les dividendes imprévus et sur cinq variables indiquant si les pronostics de bénéfices et de dividendes imprévus se confirment ou s'infirment les uns les autres, les auteurs enregistrent des données qui vont à la fois dans le sens de la corroboration et de la substitution. Les révisions des prévisions de bénéfices des analystes présentent une relation significative avec les cinq variables de corroboration, relation qui affiche un pouvoir d'explication statistiquement significatif, au-delà de celui de l'ampleur des bénéfices imprévus et des dividendes imprévus. Conformément aux prévisions, les auteurs constatent que la preuve de corroboration varie selon le degré d'imperfection de l'information relative aux bénéfices; les preuves de corroboration sont plus fortes lorsque les bénéfices varient davantage. Les auteurs font également état de constatations conformes à l'hypothèse selon laquelle les ana lystes écartent l'information relative aux bénéfices pour y substituer l'information relative aux dividendes dans le cas d'entreprises dont l'information relative aux bénéfices est imparfaite (variance élevée). Dans l'ensemble, les résultats invitent à la conclusion que les analystes utilisent l'information relative aux bénéfices et aux dividendes de manière interdépendante, une partie de cette interdépendance étant déterminée par l'imperfection de l'information communiquée en ce qui a trait aux bénéfices.     

Assessing the Resolution of Insolvent Thrift Institutions post FIRREA: The Impact of Resolution Delays

The Resolution Trust Corporation (RTC) was created by FIRREA in 1989 to manage and dispose of troubled thrifts in a manner that would minimize resolution costs. In this study, we focus on the transition of troubled thrifts from conservatorship into resolution via sales in RTC auctions. We examine the determinants of bidder participation, observed premiums, and RTC estimates of resolution costs, including the impact of resolution delays in RTC-insured-deposit-transfer and purchase-and-assumption auctions from August 1989 to November 1991. Our analysis indicates that resolution delays were associated with lower premiums and higher resolution costs. These associations are found to be economically and statistically significant and result from both the deterioration in franchise value and the deterioration in asset value while being held in conservatorship.
