摘要：We exploit changes in wind speeds at surfing locations in Switzerland as a source of variation in users' propensity to post content about their surfing activity on an online social network. We exploit this variation to test whether users' online content-generation activity is codetermined with their social ties. Economically significant effects of this type can produce positive feedback that generates local network effects in content generation. When quantitatively significant, the increased c...

摘要：This paper formally analyzes the biases related to self-reporting in hedge fund databases by matching the quarterly equity holdings of a complete list of 13F-filing hedge fund companies to the union of five major commercial databases of self-reporting hedge funds between 1980 and 2008. We find that funds initiate self-reporting after positive abnormal returns that do not persist into the reporting period. Termination of self-reporting, is followed by both return deterioration and outflows from...

摘要：The design of a matching market may affect behavior in prematch stages. In some settings, forward-looking agents might purchase low-priced properties with the intention of trading up. From a design standpoint, such behavior is undesirable. We investigate a tiered structure as a potential solution. Using a model that endogenizes prematch acquisition decisions, we show that tiers promote exchange while protecting the primary market. In the laboratory, we find that both firm revenue and total soc...

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：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. ...

摘要：In this paper, we develop a theoretical model to analyze the pricing strategies of competing retailers with asymmetric cross-selling capabilities when product demand changes. Our results suggest that retailers with better opportunities for cross-selling have higher incentives to adopt loss-leader pricing on high-demand products than retailers with low cross-selling capabilities. As a result, price dispersion of a product across retailers rises when its demand increases. The predictions of our ...

摘要：Systemic risk refers to the risk of collapse of an entire complex system as a result of the actions taken by the individual component entities or agents that comprise the system. Systemic risk is an issue of great concern in modern financial markets as well as, more broadly, in the management of complex business and engineering systems. We propose an axiomatic framework for the measurement and management of systemic risk based on the simultaneous analysis of outcomes across agents in the syste...

摘要：In this paper we study how treatment effectiveness and side effects impact the prescription decision of a risk-averse physician, and how detailing and patient feedback help reduce the physician's uncertainty in these two attributes in the erectile dysfunction category. To separately identify the impacts of effectiveness and side effects, we augment the observed prescription choices with unique data on self-reported reasons for switching in our estimation. Results show that the two new drugs Le...

摘要：We investigate the effect of financial development on the formation of European corporate groups. Because cross-country regressions are hard to interpret in a causal sense, we exploit exogenous industry measures to investigate a specific channel through which financial development may affect group affiliation: internal capital markets. Using a comprehensive firm-level data set on European corporate groups in 15 countries, we find that countries with less developed financial markets have a high...

摘要：We show that the value of commitment is fragile in many standard games. When the follower faces a small cost to observe the leader's action, equilibrium payoffs are identical to the case where the leader's actions are unobservable. Applications of our result include standard Stackelberg-Cournot and differentiated product Bertrand games, as well as forms of indirect commitment, highlighted in Bulow et al. [Bulow J, Geanakoplos J, Klemperer P (1985) Multimarket oligopoly: Strategic substitutes a...
