摘要：Given a discrete maximization problem with a linear objective function where the coefficients are chosen randomly from a distribution, we would like to evaluate the expected optimal value and the marginal distribution of the optimal solution. We call this the persistency problem for a discrete optimization problem under uncertain objective, and the marginal probability mass function of the optimal solution is named the persistence value. In general, this is a difficult problem to solve, even i...

摘要：This paper presents the. first formal examination of role of causal ambiguity as a barrier to imitation. Here, the aspiring imitator faces a knowledge (i.e., capabilities-based) barrier to imitation that is both causal and ambiguous in a precise sense of both words. Imitation conforms to a well-explicated process of learning by observing. I provide a precise distinction between the intrinsic causal ambiguity associated with a particular strategy and the subjective ambiguity perceived by a chal...

摘要：Using data generated from laboratory experiments, we test and compare the empirical accuracy of two models that focus on judgment errors associated with processing information from random sequences. We test for regime-shifting beliefs of the type theorized in Barberis et al. (Barberis, N., A. Shleifer, R. Vishny. 1998. A model of investor sentiment. J. Financial Econom. 49(3) 307-343) and for beliefs in the law of small numbers as modeled in Rabin (Rabin, M. 2002. Inference by believers in the...

摘要：We develop a branch-and-price algorithm for constructing an optimal product line using partworth estimates from choice-based conjoint analysis. The algorithm determines the specific attribute levels for each multiattribute product in a set of products to maximize the resulting product line's share of choice, i.e., the number of respondents for whom at least one new product's utility exceeds the respondent's reservation utility. Computational results using large commercial and simulated data se...

摘要：Although one of the central questions in the global strategy field is how multinational firms successfully navigate multiple and often conflicting institutional environments, we know relatively little about the effect of conflicting labor market institutions on multinational firms' strategic choice and operating performance. With its decision to invest in manufacturing operations in nearly every one of the world's largest welding markets, Lincoln Electric offers us a quasi-experiment. We lever...

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：We develop a dynamic model in which Operation Iraqi Freedom (OIF) servicemembers incur a random amount of combat stress during each month of deployment, develop posttraumatic stress disorder (PTSD) if their cumulative stress exceeds a servicemember-specific threshold, and then develop symptoms of PTSD after an additional time lag. Using Department of Defense deployment data and Mental Health Advisory Team PTSD survey data to calibrate the model, we predict that-because of the long time lags an...

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：Past research on the relationship between top management team (TMT) compositional diversity and organizational performance has paid insufficient attention to the nature of TMT team processes in interaction with TMT diversity. We fill this gap by studying how three team mechanisms (collaborative behavior, accurate information exchange, and decision-making decentralization) moderate the impact of TMT diversity on financial performance of 33 information technology firms. We focus on two fundament...

摘要：We investigate how dynamic resource substitution in service systems impacts capacity requirements and responsiveness. Inspired by the contrasting network strategies of FedEx and United Parcel Service (UPS), we study when two service classes (e. g., express or regular) should be served by dedicated resources (e. g., air or ground) or by an integrated network (e. g., air also serves regular). Using call center terminology, the question is whether to operate two independent queues or one N-networ...
