摘要:This Paper introduces a neural-net approach to perform discriminant analysis in business research. A neural net represents a nonlinear discriminant function as a pattern of connections between its processing units. Using bank default data, the neural-net approach is compared with linear classifier, logistic regression, kNN, and ID3. Empirical results show that neural nets is a promising method of evaluating bank conditions in terms of predictive accuracy, adaptability, and robustness. Limitati...

摘要:Several financial planning problems are posed as dynamic generalized network models with stochastic parameters. Examples include: asset allocation for portfolio selection, international cash management, and programmed-trading arbitrage. Despite the large size of the resulting stochastic programs, the network structure can be exploited within the solution strategy giving rise to efficient implementations. Empirical results are presented indicating the benefits of the stochastic network approach...

摘要:The control relationship between project managers and team members is a central aspect of the working of any Information System (I/S) design team. This paper combines research on managerial control and team-member control in order to explore a range of control behaviors that can affect the performance of an I/S design team. Measures are developed and validated for managerial control and team-member control from both an outcome and a process perspective. Results from a study of 41 actual I/S de...

摘要:We explore the extent to which R&D and advertising expenditures generate a comparative advantage that allows firms to earn supranormal profits. After controlling for unobserved firm-specific factors and the feedback between discretionary expenditures and profitability, our results suggest substantially lower accounting and stock market returns to R&D and advertising than indicated in previous research. Isolating mechanisms, which prevent imitation, do not appear sufficient for either R&D or ad...

摘要:Management science and decision science have grown exponentially since midcentury. Two closely-related fields central to this growth are multiple criteria decision making (MCDM) and multiattribute utility theory (MAUT). This paper comments on the history of MCDM and MAUT and discusses topics we believe are important in their continued development and usefulness to management science over the next decade. Our aim is to identify exciting directions and promising areas for future research.

摘要:This paper presents an examination of certain issues in Frequency Domain Experimentation (FDE) for discrete event simulation. Experimental results are presented to demonstrate that (i) conclusions drawn from FDE are dependent on the oscillation frequency and unless frequencies are chosen carefully, misleading results can be obtained; (ii) interpretation of results from frequency domain experiments are fundamentally different from the interpretation of results from regression analysis-specifica...

摘要:This paper describes a phenomenon called locally rotional decision-making, in which the mere presence of information may have dysfunctional consequences even if decision makers do not process the information incorrectly. Using the results from an experiment conducted with a strategic market simulation game, we find that the accessibility of information results in a disposition to focus on those components of decision-making most clearly addressed by the information. If these are not the compon...

摘要:This exploratory study of 57 large bankruptcies and 57 matched survivors examined the top management team (TMT) characteristics associated with major corporate failure. Prior research was used to guide selection of specific team characteristics for study. Not only did the failing firms show significant annual, or cross-sectional, divergence from survivors on several indicators of TMT composition, but also those divergences became more pronounced, even accelerating, over the last five years of ...

摘要:Strategic management researchers have shown increasing awareness of the importance of the concept of risk at the strategic level. In recognition of this interest, this research adopts a commonly used conceptualization of risk and shows how this conceptualization leads to a new measure of risk, based upon the chance of loss of relative position within a set of firms. This framework is shown to be particularly appropriate for strategy research. Information contained in probability distributions ...

摘要:The performance of in vitro fertilization-embryo transfer (IVF-ET) programs is summarized typically as the average probability of achieving pregnancy per cycle. Variation in conception probabilities across women reduces the usefulness of such an aggregate measure. More relevant is the conditional probability of achieving pregnancy on a given cycle following a number of failed IVF-ET attempts. We construct a model that accurately describes 1,257 treatment cycles performed at Yale over 571 diffe...
