摘要：Since Osborn's Applied Imagination book in 1953 (Osborn, A. F. 1953. Applied Imagination: Principles and Procedures of Creative Thinking. Charles Scribner's Sons, New York), the effectiveness of brainstorming has been widely debated. While some researchers and practitioners consider it the standard idea generation and problem-solving method in organizations, part of the social science literature has argued in favor of nominal groups, i.e., the same number of individuals generating solutions in...

摘要：This paper compares the innovation performance of established pharmaceutical firms and biotech companies, controlling for differences in the scale and scope of research. We develop a structural model to analyze more than 3,000 drug research and development projects advanced to preclinical and clinical trials in the United States between 1980 and 1994. Key to our approach is careful attention to the issue of selection. Firms choose which compounds to advance into clinical trials. This choice de...

摘要：Recent research has advanced our understanding of how people use the advice of others to update their beliefs. Because groups and teams play a significant role in organizations and collectively are wiser than their individual members, it is important to understand their influence on belief revision as well. I report the results of four studies examining intuitions about group wisdom and the informational influence of groups. In their overt assessments, experimental participants rated larger gr...

摘要：Mutual fund companies selectively advertise their better-performing funds. However, investors respond to advertised performance data as if those data were unselected (i.e., representative of the population). We identify the failure to discount selected or potentially selected data as selection neglect. We examine these phenomena in an archival study (Study 1) and two controlled experiments (Studies 2 and 3). Study 1 identifies selection bias in mutual fund advertising by showing that the media...

摘要：Prior literature has documented the performance benefits from the use of electronic data interchange (EDI) and the Internet. Using purchase and fulfillment records from the U. S. government's Federal Supply Service, we provide a direct comparison of performance between a private network EDI channel and an Internet electronic market. Performance is measured using order cycle time and complete orders fulfilled. Our findings show that the Internet-based electronic market outperforms the EDI-based...

摘要：Among 1,000 German brokerage clients for whom both survey responses and actual trading records are available, investors who report enjoying investing or gambling turn over their portfolio at twice the rate of their peers. Including entertainment attributes as additional explanatory variables in cross-sectional regressions of portfolio turnover on objective investor attributes more than doubles the fraction of the total variation of portfolio turnover that can be explained. The results are robu...

摘要：We report on a field study demonstrating systematic differences between the preferences people anticipate they will have over a series of options in the future and their subsequent revealed preferences over those options. Using a novel panel data set, we analyze the film rental and return patterns of a sample of online DVD rental customers over a period of four months. We predict and find that should DVDs (e. g., documentaries) are held significantly longer than want DVDs (e. g., action films)...

摘要：W e develop and test an optimization model for maximizing response rates for online marketing research survey panels. The model consists of (1) a decision tree predictive model that classifies panelists into states and forecasts the response rate for panelists in each state and (2) a linear program that specifies how many panelists should be solicited from each state to maximize response rate. The model is forward looking in that it optimizes over a finite horizon during which S studies are to...

摘要：Diagnostic knowledge-based systems are used in a variety of application domains to support classification decisions. The effectiveness of such systems often decreases as the application environment or user preferences change over time. Hence, frequent adjustments to the system knowledge by a human expert become necessary. We study the problem of determining the optimal amount of effort that should be exerted to maintain the system over a planning horizon (finite or infinite). Using the receive...

摘要：Firms normally disclose quality information to consumers using two alternative formats: either directly to consumers or indirectly through downstream retailers. This study investigates optimal disclosure strategies/formats in a channel setting with bilateral monopolies. It shows that retail disclosure leads to more equilibrium information revelation. This is because the manufacturer can, through wholesale price cuts, partially absorb the retailer's effective disclosure cost and thus increase t...
