摘要：How does competition among economic actors determine the value that each is able to appropriate? We provide a formal, general framework within which this question can be posed and answered, and then provide several results. Chief among them is a condition that is both required for, and guarantees, value appropriation. We apply our methodology to (i) assess the familiar notion that uniqueness, inimitability, and competition imply value appropriation, and (ii) determine the value appropriation p...

摘要：We consider the problem of allocating demand arising from multiple products to multiple production facilities with finite capacity and load-dependent lead times. Production facilities can choose to manufacture items either to stock or to order. Products vary in their demand rates, holding and backordering costs, and service-level requirements. We develop models and solution procedures to determine the optimal allocation of demand to facilities and the optimal inventory level for products at ea...

摘要：Companies innovating in dynamic environments face the combined challenge of unforeseeable uncertainty (the inability to recognize the relevant influence variables and their functional relationships; thus, events and actions cannot be planned ahead of time) and high complexity (large number of variables and interactions; this leads to difficulty in assessing optimal actions beforehand). There are two fundamental strategies to manage innovation with unforeseeable uncertainty and complexity: tria...

摘要：This paper shows that business groups in emerging economies exert dual effects on innovation. While groups facilitate innovation by providing institutional infrastructure, groups also discourage innovation by creating entry barriers for nongroup firms and thereby inhibit the proliferation of new ideas. This pattern reflects an evolutionary process in which the interplay of the availability of innovation infrastructure and variety of ideas influences the level of innovation in an industry. We s...

摘要：After a merger, company officials face the challenge of making compensation schemes uniform and of redesigning teams with managers from companies with different incentives, work habits, and recruiting methods. In this paper, we investigate the relationship between executive pay and performance after a merger by dissociating the respective influence of shifts, which occur in both compensation incentives and team composition. The results of a real task experiment conducted with managers within a...

摘要：This paper develops the first operational tests of portfolio efficiency based on the general stochastic dominance (SD) criteria that account for an infinite set of diversification strategies. The main insight is to preserve the cross-sectional dependence of asset returns when forming portfolios by reexpressing the SD criteria in T-dimensional Euclidean space, with elements representing rates of return in T different states of nature. We characterize subsets of this state-space that dominate a ...

摘要：To provide useful practical insight into the performance of service-oriented (non-revenue-generating) call centers, which often provide low-to-moderate quality of service, this paper investigates the efficiency-driven (ED), many-server heavy-traffic limiting regime for queues with abandonments. Attention is focused on the M/M/s/r + M model, having a Poisson arrival process, exponential service times, s servers, r extra waiting spaces, exponential abandon times (the final +M), and the first-com...

摘要：Living donors are a significant and increasing source of livers for transplantation, mainly because of the insufficient supply of cadaveric organs. We consider the problem of optimally timing a living-donor liver transplant to maximize the patient's total reward, such as quality-adjusted life expectancy. We formulate a Markov decision process (MDP) model in which the state of the process is described by patient health. We derive structural properties of the MDP model, including a set of intuit...

摘要：We reflect on the evolution of the strategy field as seen through the window of Management Science. Reflecting the diverse disciplinary roots of strategy research, we identify a broad-ranging body of work that varies with respect to the assumptions made regarding individual rationality and the level of analysis at which the research is carried out. We argue that recent developments begin to delineate a potentially unifying conceptual framework for treating the field's defining questions-the co...
