摘要：We study the relationship between the risk preferences of individuals and the risk preferences of the aggregate economy. To emphasize the vast differences that can occur between individual and market preferences brought about through aggregation, we assume an economy consisting entirely of risk seekers. We show that such individuals can lead to an aggregate economy that is risk averse. The converse is also true. An aggregate economy that exhibits risk aversion does not imply an economy of indi...

摘要：During development of an innovative product there is often considerable uncertainty about component production cost, and it is of interest for both the manufacturer and the supplier to engage in a collaborative effort to reduce this uncertainty and lower the expected cost. Despite the obvious benefits this brings, the supplier may be reluctant to collaborate as he fears revealing his proprietary cost information. We investigate how information asymmetry and procurement contracting strategies i...

摘要：We model the decision-making process of callers in call centers as an optimal stopping problem. After each waiting period, a caller decides whether to abandon a call or continue to wait. The utility of a caller is modeled as a function of her waiting cost and reward for service. We use a random-coefficients model to capture the heterogeneity of the callers and estimate the cost and reward parameters of the callers using the data from individual calls made to an Israeli call center. We also con...

摘要：The simultaneous production of different outputs (coproducts) is observed in the chemical, material, mineral, and semiconductor industries among others. Often, as with microprocessors, the outputs differ in quality in the vertical sense and firms classify the output into different grades (products). We analyze product line design and production for a firm operating a vertical coproduct technology. We examine how the product line and profit are influenced by the production cost and output distr...

摘要：Companies frequently expand their production capacity through the acquisition of new organizational unit. This study analyzes how the performance of existing units is affected by the acquisition of another unit. The research focuses on three mechanisms: managerial distraction, resource transfer, and knowledge sharing. These mechanisms are studied in the context of existing units and acquired units with different levels of proximity and similarity between them. Using a detailed data set from an...

摘要：Many important decisions are routinely made by transient and temporary teams, which perform their duty and disperse. Team members often continue making similar decisions as individuals. We study how the experience of team decision making affects subsequent individual decisions in two seminal probability and reasoning tasks, the Monty Hall problem and the Wason selection task. Both tasks are hard and involve a general rule, thus allowing for knowledge transfers, and can be embedded in the conte...

摘要：The recent financial crisis highlights the importance of market crashes and the subsequent market illiquidity for optimal portfolio selection. We propose a tractable and flexible portfolio choice model where market crashes can trigger switching into another regime with a different investment opportunity set. We characterize the optimal trading strategy in terms of coupled integro-differential equations and develop a quite general iterative numerical solution procedure. We conduct an extensive ...

摘要：We analyze the implications of the decision to spawn or to retain a new product for the nature and evolution of the firm. In our model, a new product is spawned if the fit between the product and its parent firm organization is not adequate. We focus on the impact of the firm's history of spawning decisions on firm characteristics such as size, focus, profitability, and innovativeness, and analyze its role in shaping firm dynamics. In accordance with the empirical literature, our model predict...

摘要：In the majority of developed countries, the level of influenza vaccination coverage in all age groups is suboptimal. Hence, the authorities offer different kinds of incentives for people to become vaccinated such as subsidizing immunization or placing immunization centers in malls to make the process more accessible. We built a theoretical epidemiological game model to find the optimal incentive for vaccination and the corresponding expected level of vaccination coverage. The model was support...

摘要：We consider projects with uncertain activity times and the possibility of expediting, or crashing, them. Activity times come from a partially specified distribution within a family of distributions. This family is described by one or more of the following details about the uncertainties: support, mean, and covariance. We allow correlation between past and future activity time performance across activities. Our objective considers total completion time penalty plus crashing and overhead costs. ...
