摘要：Value-at-Risk (VaR) is one of the most widely accepted risk measures in the financial and insurance industries, yet efficient optimization of VaR remains a very difficult problem. We propose a computationally tractable approximation method for minimizing the VaR of a portfolio based on robust optimization techniques. The method results in the optimization of a modified VaR measure, Asymmetry-Robust VaR (ARVaR), that takes into consideration asymmetries in the distributions of returns and is co...

摘要：Recent court decisions, starting with the State Street decision in 1998, allow business methods to be patentable and now give financial institutions the option to seek patent protection for financial innovations. This new patentability paradigm and the heterogeneity of characteristics associated with financial innovations pose an immediate decision problem for senior management: what to patent. We present a parsimonious decision framework that answers this question. We show that for innovation...

摘要：Sales technology has been touted as a primary tool for enhancing customer relationship management. However, empirical research is sparse concerning the use of information technology (IT) and its effects on the relationship between salespersons and customers. Using an interdisciplinary research approach, we extend task-technology-fit (TTF) theory by examining the mechanisms through which use of IT by the sales force influences salesperson performance. We test a model that incorporates salespers...

摘要：We investigate contracting and information sharing in two competing supply chains, each consisting of one manufacturer and one retailer. The two supply chains are identical, except they may have different investment costs for information sharing. The problem is studied using a two-stage game. In the first stage, the manufacturers decide whether to invest in information sharing. In the second stage, given the information structure created in the first stage, the manufacturers offer contracts to...

摘要：We provide new rationales for corporate venturing, based on competition for talented managers. As returns to venturing increase, firms engage in corporate venturing for reasons other than, capturing these returns. First, higher venturing returns increase managerial compensation, to which firms respond by increasing incentives. Managers increase effort, prompting firms to reallocate them to new ventures, where the marginal product of effort is highest. Second, as returns to venturing become lar...

摘要：In this paper, we present a modulated Poisson process model to describe and analyze arrival data to a call center. The attractive feature of this model is that it takes into account both covariate and time effects on the call volume intensity, and in so doing, enables us to assess the effectiveness of different advertising strategies along with predicting the arrival patterns. A Bayesian analysis of the model is developed and an extension of the model is presented to describe potential heterog...

摘要：In this paper, we consider the classical multifare, single-resource (leg) problem in revenue management for the case where demand information is limited. Our approach employs a competitive analysis, which guarantees a certain performance level under all possible demand scenarios. The only information required about the demand for each fare class is lower and upper bounds. We consider both competitive ratio and absolute regret performance criteria. For both performance criteria, we derive the b...

摘要：Every organization is confronted by employee errors. Situational learning orientation may mitigate an employee's tendency to err. A situational learning orientation refers to the extent to which employees share the perception that there is an emphasis on improvement and on actively searching for additional knowledge and feedback in their department. The present study suggests that situational learning orientation interacts with two other organizational factors-autonomy and voice-as it influenc...

摘要：Although organizations appear to learn from obvious failures, we argue that it is harder for them to learn from near-misses-events in which chance played a role in averting failure. In this paper, we formalize the concept of near-misses and hypothesize that organizations and managers fail to learn from near-misses because they evaluate such events as successes and thus feel safer about the situation. We distinguish perceived (felt) risk from calculated statistical risk and propose that lower l...

摘要：ast research in new product development (NPD) has conceptualized prototyping as a design- build- testanalyze cycle to emphasize the importance of the analysis of test results in guiding the decisions made during the experimentation process. New product designs often involve complex architectures and incorporate numerous components, and this makes the ex ante assessment of their performance dif. cult. Still, design teams often learn from test outcomes during iterative test cycles enabling them...
