摘要：The recorded transactions of venture capital investments permit a direct examination of the Braudel hypothesis that regional markets evolve dynamically and interdependently in reference to a global system. This hyothesis contradicts the popular belief that regional financial development is anchored in dense clusters. Using methods of complex graphs, we analyze 159,561 transactions over nearly 45 years to demonstrate the rapid emergence of a national network of syndications. A giant component e...

摘要：We study the global diffusion of ISO 9000 and ISO 14000 certification using a network diffusion framework. We start by investigating the presence and nature of contagion effects by defining alternative cross-country networks and testing their relative strength. Second, we study how the rate of diffusion differs between the two standards and between early- and later-adopting countries. Third, we identify which countries had more influence on diffusion than others. Empirically, we build a diffus...

摘要：Most performance evaluation models in the operations management literature implicitly assume that tasks possess standardized completion criteria. However, in many systems, particularly service and professional work, judgment is frequently required to determine how much time to allocate to a task. In this paper, we show that introducing discretion in task completion adds a fourth variability buffer, quality, to the well-known buffers of capacity, inventory and time. To gain insight into the man...

摘要：Neoclassical models of strategic behavior have yielded many insights into competitive behavior, despite the fact that they often rely on a number of assumptions-including instantaneous market clearing and perfect foresight-that have been called into question by a broad range of research. Researchers generally argue that these assumptions are good enough to predict an industry's probable equilibria, and that disequilibrium adjustments and bounded rationality have limited competitive implication...

摘要：This paper explores inconsistencies that occur in utility measurement under risk when expected utility theory is assumed and the contribution that prospect theory and some other generalizations of expected utility can make to the resolution of these inconsistencies. We used five methods to measure utilities under risk and found clear violations of expected utility. Of the theories studied, prospect theory was the most consistent with our data. The main improvement of prospect theory over expec...

摘要：Despite the mathematical properties and algorithmic features of an interactive method, that method's success usually lies in the kind of information it requires from the decision maker. In some cases, this information constrains the decision maker. If she does not find it easy and comfortable to answer the questions posed by the algorithm, then she will very likely give inconsistent answers, and the method will fail to find her most preferred solution. Therefore, it is of interest to find rela...

摘要：Technological developments combine previously distinct technologies that result in converging markets. In converging markets, firms from different industries compete against each other, often for the first time. We propose that firms introducing new products in converging markets will learn vicariously from other firms in the market. Further, we propose that this learning will vary across the dual-technology frontier (DTF), where the high-technology frontier (HTF) and low-technology frontier (...

摘要：We consider a multicomponent, single-product assemble-to-order (ATO) system that faces frequent, component-based technology innovations. For each component, there are two technologies with overlapping life cycles coexisting in the market. All cost parameters associated with each technology (procurement cost, salvage value, etc.) evolve dynamically. We investigate two technology-inventory coordination schemes, one is at the strategic level, where technology and inventory decisions are sequentia...

摘要：A systematic understanding of industry dynamics is critical to strategy research because individual firm performance dynamics both reflect and affect change at the industry level. Descriptive research on industry dynamics has identified a dominant pattern where prices fall, output rises, and the number of firms rises and then falls over time. Several models have been advanced to explain these patterns, with a particular focus on explaining why a shakeout in the number of firms occurs. In the m...

摘要：We consider a finite-state, finite-action, infinite-horizon, discounted reward Markov decision process and study the bias and variance in the value function estimates that result from empirical estimates of the model parameters. We provide closed-form approximations for the bias and variance, which can then be used to derive confidence intervals around the value function estimates. We illustrate and validate our findings using a large database describing the transaction and mailing histories f...
