Relative wealth concerns can affect risk-taking behavior, as the payoff to a marginal dollar of wealth depends on the wealth of others. In particular, status concerns that arise endogenously due to competition in the marriage market can lead to greater risktaking if the more desirable mates prefer wealthier suitors. We evaluate empirically the importance of this effect in a high-stakes setting ...

We measure the impact of direct-to-consumer television advertising (DTCA) by drug manufacturers. Our identification strategy exploits shocks to local advertising markets generated by the political advertising cycle and a regulatory intervention affecting a single product. We find evidence of significant business stealing effects among branded, advertised drugs. In addition, we show positive spi...

Assuming the classic contingent claim setting, a number of …nancial asset demand tests of Expected Utility have been developed and implemented in experimental settings. However the domain of preferences of these asset demand tests di¤er from the mixture space of distributions assumed in the traditional binary lottery laboratory tests of von Neumann-Morgenstern Expected Utility preferences. We d...

This article reports the results of a 1977 field survey of managers in fifty plants in the United States and Canada that have recently instituted twelve-hour shifts in continuous operation situations in the chemical and petroleum industries. The authors report that in all the plants studied the shift change has significantly improved morale without impairing efficiency, job safety, or workers' ...

We characterize a class of dynamic stochastic games that we call separable dynamic games with noisy transitions and establish that these widely used models are protocol invariant provided that periods are sufficiently short. Protocol invariance means that the set of Markov perfect equilibria is nearly the same irrespective of the order in which players are assumed to move within a period. Proto...

We consider the advantages and disadvantages of stakeholder-oriented firms that are concerned with employees and suppliers as well as shareholders compared to shareholderoriented firms. Societies with stakeholder-oriented firms have higher prices, lower output, and can have greater firm value than shareholder-oriented societies. In some circumstances, firms may voluntarily choose to be stakehol...

Agents with standard, time-separable preferences do not care about the temporal distribution of risk. This is a strong assumption. For example, it seems plausible that a consumer may …nd persistent shocks to consumption less desirable than uncorrelated ‡uctuations. Such a consumer is said to exhibit temporal risk aversion. This paper examines the implications of temporal risk aversion for asset...

Previous literature has shown that land use regulations influence where people choose to live within the U.S. by impacting housing prices. In this paper, we study the impact of these same regulations on another component of population growth, fertility rates. First, we employ a dataset on the stringency of land restrictions using court based measures created by Ganong and Shoag (2017). We add t...

We examine the importance of asset pricing anomalies for the real economy. When firms interpret public information in the way it is reflected in market prices, informational inefficiencies manifesting in financial markets as anomalies can cause material real inefficiencies. We estimate the joint dynamic distribution of firm characteristics that have been linked to anomalies and other firm varia...

This study aimed to identify parasitoid species of frugivorous larvae and to describe the tritrophic interactions involving wild fruits, frugivorous insects and their natural enemies at Adolpho Ducke Forest Reserve (RFAD) (Manaus, AM, Brazil). Collections were performed in four 1 km2 quadrants in the corners of the RFAD. The wild fruits were collected inside the forest in access trails leading ...
