摘要：Contests (or tournaments) are pervasive in organizations. They help performance evaluation by eliminating common shocks affecting agents' performance. However, tournaments are less effective when participants have heterogeneous ability because participants may conclude that the ability gap is too large to be overcome by their effort. Our theoretical analysis shows that a similar loss of motivation arises when tournaments take place over multiple periods because interim performance acts in a wa...

摘要：Empirical martingale simulation (EMS) was proposed by Duan and Simonato (Duan, J.-C., J.-G. Simonato. 1998. Empirical martingale simulation for asset prices. Management Sci. 44(9) 1218-1233) as an adjustment to the standard Monte Carlo simulation to reduce simulation errors. The EMS price estimator of derivative contracts was shown to be asymptotically normally distributed in Duan et al. (Duan, J.-C., G. Gauthier, J.-G. Simonato. 2001. Asymptotic distribution of the EMS option price estimator....

摘要：We consider how two networked large-scale service systems that normally operate separately, such as call centers, can help each other when one encounters an unexpected overload and is unable to immediately increase its own staffing. Our proposed control activates serving some customers from the other system when a ratio of the two queue lengths ( numbers of waiting customers) exceeds a threshold. Two thresholds, one for each direction of sharing, automatically detect the overload condition and...

摘要：Recent research has advanced our understanding of how people use the advice of others to update their beliefs. Because groups and teams play a significant role in organizations and collectively are wiser than their individual members, it is important to understand their influence on belief revision as well. I report the results of four studies examining intuitions about group wisdom and the informational influence of groups. In their overt assessments, experimental participants rated larger gr...

摘要：In this paper, we use a unique data set on the Italian interdealer bond market to empirically estimate the process of strategic experimentation. The results show how the information generated in the process of interdealer trading affects the incentive to experiment. Upon receipt of an order, dealers deliberately engage in trade with other dealers either to exploit the information contained in the order they receive or, if they are uncertain about its quality, to assess it by actively experimen...

摘要：One important decision firms must make is to select the product line ( characteristics and number of products) to offer consumers. This paper explores the effect of the interaction between consumer evaluation costs and pricing on the optimal product line length to offer consumers. Before deciding to buy a product among all products offered, a consumer learns the product line length. Given the product line length, a consumer decides whether to evaluate the products available and their prices. T...
