摘要：Stochastic programming and distributionally robust optimization seek deterministic decisions that optimize a risk measure, possibly in view of the most adverse distribution in an ambiguity set. We investigate under which circumstances such deterministic decisions are strictly outperformed by random decisions, which depend on a randomization device producing uniformly distributed samples that are independent of all uncertain factors affecting the decision problem. We find that, in the absence o...

摘要：This study examines the effect of psychological contract breach on budgetary misreporting. Psychological contracts are mental models or schemas that govern how employees understand their exchange relationships with their employers. Psychological contract breach leads to feelings of violation and can occur even when employees' economic contracts are fulfilled. We study the effects of psychological contract breach on three common types of employee participation in budgeting that differ in the de...

摘要：A problem solver (PS) is an agent who when interacting with other agents does not put himself in their shoes but rather chooses a best response to a uniform distribution over all possible configurations consistent with the information he receives about the other agents' moves. We demonstrate the special features of a PS by analyzing a modified coordination game. In the first stage, each of the other participants-who are treated as conventional players-chooses a location. The PS then receives s...

摘要：To what extent does expertise depend on context? We observe professionals perform a task that is logically isomorphic to-but contextually distinct from-a familiar task in which they are skilled. We find that performance plummets when contextual cues disappear, suggesting that the expertise we observe on the familiar task is more heuristic than conceptual and does not travel far.

摘要：Interbank financial networks enable banks to share the risks in their assets but potentially also increase systemic spillovers of insolvency from one bank to others in the network. We model a renegotiation game to explicitly examine the forgiveness of commitments of insolvent banks by solvent banks to limit the systemic transmission of financial distress. The assets of the insolvent bank can be appropriated by the forgiving bank in the two-bank network, but not the three-bank network, where th...

摘要：Firms have an incentive to test competitors' products to reveal violations of safety and environmental standards, in order to have competitors' products blocked from sale. This paper shows that testing by a regulator crowds out testing by competitors, and can reduce firms' efforts to comply with the product standard. Relying on competitor testing (i.e., having the regulator test only to verify evidence of violations provided by competitors) is most effective in large or concentrated markets in...

摘要：This paper analyzes the energy efficiency (EE) investment decisions of a capital-constrained manufacturer that competes with an alternative supplier for the business of a large industrial buyer. Through a series of game-theoretic models, we characterize when it is beneficial for the buyer to offer EE instruments, including assessment assistance and procurement commitment, and how these instruments interact with third-party assessment assistance to affect the supplier's EE investment level. We ...

摘要：Using comprehensive data on London Interbank Offer Rate (Libor) submissions from 2001 through 2012, we provide evidence consistent with banks manipulating Libor to profit from Libor-related positions and to signal their creditworthiness during distressed times. Evidence of manipulation is stronger for banks that were eventually sanctioned by regulators and disappears for all banks in the aftermath of the Libor investigations that began in 2010. Our findings suggest that the threat of large pen...

摘要：Classical queueing theory has typically focused on customers, and server availability has been taken for granted. However, data accessibility and the emergence of complex service systems, for example, call centers, revealed the need to stochastically model the complex behavior of servers. In this work, we propose a new model that accommodates such behavior; we call it Erlang-S, where S stands for servers. Our model assumes a pool of present servers, some of whom are available to serve customer...

摘要：We estimate the effect of supply chain proximity on product quality. Merging four automotive data sets, we create a supply chain sample that reports the failure rate of 27,807 auto components, the location of 529 upstream component factories, and the location of 275 downstream assembly plants. We find that defect rates are higher when upstream and downstream factories are farther apart. Specifically, we estimate that increasing the distance between an upstream component factory and a downstrea...
