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. 相似文献

Abstract The tables for the Friedman rank-test arc extended using a sampling method. A table is given for the traditional significance levels .01, .025, .05 and .10 for number of blocks equal to 7 and 8 and for treatments of size 6 and 7. A brief discussion of available tables is also included along with an example of an application. 相似文献

A recent article in this journal by Dran (1991) suggests that the usual treatment of degree of operating leverage (DOL) is
misleading because it improperly attributes the DOL to the ratio of fixed to total costs rather than the closeness of the
firm’s output to breakeven. Managerial economics texts are clear in identification of DOL as an elasticity concept which varies
with the nearness to break-even. Examples associating DOL with the relative level of fixed cost arise from association of
higher fixed costs with higher breakeven points, and this appears to be the normal economic relationship. 相似文献

The case is investigated when Hoeffding's one sample U–statistic theorem for the sample variance S2 is not applicable. It is shown that this occurs only when the parent distribution is the two–point distribution with jumps of equal magnitude. For this exceptional case the standardised S2 is shown to converge in distribution to (1 – V )√2, where V has chi–square distribution with one degree of freedom. 相似文献

Summary In this paper some inequalities for the variance and covariance of convex monotone functions of order statistics from ordered families of distributions are presented. The considered order relations in the set of distributions are the stochastic ordering relation and the convex ordering relation. Stochastic comparisons of spacings and their sums are also given. As corollaries the results for IFR and DFR distributions are obtained. 相似文献
