摘要:Across consequential attributions of attitudes, ability, emotions, and morality, people make correspondent inferences. People infer stable personality characteristics from others' behavior, even when that behavior is caused by situational factors. We examined the structure of correspondent inferences and report the development and validation of an instrument measuring individual differences in this correspondence bias (a Neglect of External Demands scale, or NED). The NED is internally consist...

摘要:Resource pooling strategies have been widely used in industry to match supply with demand. However, effective implementation of these strategies can be challenging. Firms need to integrate the heterogeneous service level requirements of different customers into the pooling model and allocate the resources (inventory or capacity) appropriately in the most effective manner. The traditional analysis of inventory pooling, for instance, considers the performance metric in a centralized system and d...

摘要:We propose a new medical evacuation (MEDEVAC) model with endogenous uncertainty in the casualty delivery times. The goal is to provide timely evacuation and medical treatment to injured soldiers. The model enforces the Golden Hour evacuation doctrine, attempts to maximize the expected number of severely injured soldiers evacuated within one hour without delay, and represents the availability of air ambulances as an endogenous source of uncertainty. The MEDEVAC model is a mixed-integer nonlinea...

摘要:Telemedical physician triage (TPT) is an example of a hierarchical knowledge-based service system (HKBSS) in which a second level of decision agent (telemedical physician) renders a decision on cases referred to him or her by the primary level agents (triage nurses). Managing the speed-versus-quality trade-off in such systems presents a unique challenge because of the interplay between agent knowledge and flow of work between the two levels. We develop a novel model of agent knowledge, based o...

摘要:Some corporations attempt to lessen their tax burden through involvement in the legislative process. We identify firms that contributed to congressional candidates who favor reductions in the U.S. corporate statutory tax rate. This support created a temporary incentive to manage effective tax rates (ETRs) up. We document that these firms increased their reported effective tax rate in the two calendar quarters preceding the 2012 election relative to adjacent periods and other firms supporting c...

摘要:In a continuous-time portfolio selection model with N risky assets and K state variables driving their risk and return parameters, we derive simple expressions for the allocation to each asset in the K + 1 risky funds of the (K + 2)-fund separation theorem. We show that the allocation to any given risky asset in each fund can be written in terms of the parameters of a regression of the excess returns of this asset on those of the N - 1 remaining assets. We also use these parameters to provide ...

摘要:Market competition may lead to mismatch between supply and demand. That is, overpricing may give rise to underselling, and underpricing may yield stockout. Capacity sharing is a common practice to align excessive capacity with excessive demand. Yet, the strategic interaction between competition and capacity sharing has not been adequately addressed. In this paper, we investigate optimal strategies and firm profitability of capacity sharing between competing firms under both ex ante and ex post...

摘要:We propose and implement a direct test of the hypothesis of oligopolistic competition in the U.S. underwriting market against the alternative of implicit collusion among underwriters. We construct a simple model of interaction between heterogeneous underwriters and heterogeneous firms and solve it under two alternative assumptions: oligopolistic competition among underwriters and implicit collusion among them. The two solutions lead to different equilibrium relations between the compensation o...

摘要:This paper develops and estimates an economic model of the costs and beliefs required to rationalize household direct stock ownership. In the model, investors believe they can learn information about individual stock returns through costly research. The model identifies the distributions of both research costs and beliefs about the predictability of individual stock returns. Identification depends only on households' wealth and portfolio choices. The model also provides a novel explanation for...

摘要:Tests of gift exchange, wherein agents receive excess wages which are noncontingent on performance in one-shot settings, have yielded contradictory evidence: they sometimes find effort boosts, consistent with gift exchange, whereas they sometimes find no effort increases, consistent with a standard model. We identify eight confounds that could have led to the mixed evidence-agent disutility from being viewed as selfish, small samples, insufficient wage raises, an effort ceiling, fatigue, selec...
