摘要：This paper develops an economic theory of the costs and benefits of corporate culture-in the sense of shared beliefs and values-in order to study the effects of culture clash in mergers and acquisitions. I first use a simple analytical framework to show that shared beliefs lead to more delegation, less monitoring, higher utility (or satisfaction), higher execution effort (or motivation), faster coordination, less influence activities, and more communication, but also to less experimentation an...

摘要：The use of H-1B and other work visas to hire foreign information technology (IT) professionals in the United States has attracted significant controversy and policy debates. On one hand, hiring high-skill foreign IT professionals on work visas can be advantageous for U.S. firms and the overall economy. On the other hand, high-skill immigration can adversely impact the wages of foreign and American IT professionals. This study uses data on skills and compensation of more than 50,000 IT professi...

摘要：In this paper, we consider a class of two-stage stochastic optimization problems arising in the protection of vital arcs in a critical path network. A project is completed after a series of dependent tasks are all finished. We analyze a problem in which task finishing times are uncertain but can be insured a priori to mitigate potential delays. A decision maker must trade off costs incurred in insuring arcs with expected penalties associated with late project completion times, where lateness p...

摘要：Young male CEOs appear to be combative: they are 4% more likely to be acquisitive and, having initiated an acquisition, they are over 20% more likely to withdraw an offer. Furthermore, a young target male CEO is 2% more likely to force a bidder to resort to a tender offer. We argue that this combative nature is a result of testosterone levels that are higher in young males. Testosterone, a hormone associated with male dominance seeking, has been shown to influence prospects for a cooperative o...

摘要：We explore why some employees may be at a disadvantage in searching for information in organizations. The small-world argument in social network theory emphasizes that people are, on average, only a few connections away from the information they seek. However, we argue that such a network structure does not benefit everyone: some employees may have longer search paths in locating knowledge in an organization-their world may be large. We theorize that this disadvantage is the result of more tha...

摘要：In response to competitive pressures, firms are increasingly adopting revenue management opportunities afforded by advances in information and communication technologies. Motivated by these revenue management initiatives in industry, we consider a dynamic pricing problem facing a firm that sells given initial inventories of multiple substitutable and perishable products over a finite selling horizon. Because the products are substitutable, individual product demands are linked through consumer...

摘要：We consider the problem of staffing call centers with multiple customer classes and agent types operating under quality-of-service (QoS) constraints and demand rate uncertainty. We introduce a formulation of the staffing problem that requires that the QoS constraints are met with high probability with respect to the uncertainty in the demand rate. We contrast this chance-constrained formulation with the average-performance constraints that have been used so far in the literature. We then propo...

摘要：This paper provides a methodology for detecting management fraud using basic financial data. The methodology is based on support vector machines. An important aspect therein is a kernel that increases the power of the learning machine by allowing an implicit and generally nonlinear mapping of points, usually into a higher dimensional feature space. A kernel specific to the domain of finance is developed. This financial kernel constructs features shown in prior research to be helpful in detecti...

摘要：Scientists and engineers in small firms are far more likely than their large firm counterparts to enter entrepreneurship. We label this phenomenon the small firm effect and explore its origins. In particular, we identify four classes of explanations for the small firm effect-preference sorting, ability sorting, opportunity cost, and the possibility that workers in small firms develop entrepreneurial human capital-and examine the empirical evidence for each. We find that preference sorting does...

摘要：Biproportional apportionment methods provide two-way proportionality in electoral systems where the electoral region is subdivided into electoral districts. The problem is to assign integral values to the elements of a matrix that are proportional to a given input matrix, and such that a set of row-and column-sum requirements are fulfilled. In a divisor-based method for biproportional apportionment, the problem is solved by computing appropriate row and column divisors, and by rounding the quo...
