摘要：We study peer effects in the workplace. Specifically, we investigate whether, how, and why the productivity of a worker depends on the productivity of coworkers in the same team. Using high-frequency data on worker productivity from a large supermarket chain, we find strong evidence of positive productivity spillovers from the introduction of highly productive personnel into a shift. Worker effort is positively related to the productivity of workers who see him, but not workers who do not see ...

摘要：We analyze models with inter jurisdictional spillovers among heterogeneous jurisdictions, such as CO2 emissions that affect the global environment. Each jurisdiction's emissions depend upon the local stock of capital, which is inter-jurisdictionally mobile and subject to local taxation. In important cases, decentralized policymaking leads to efficient resource allocation, even in the complete absence of corrective interventions by higher-level governments or coordination of policy through Coas...

摘要：This paper reports the results of all experiment on exclusive contracts. We replicate the strategic environment described by Rasmusen, Ramseyer, and Wiley (1991) and Segal and Whinston (2000). Our findings are as follows. First, when the buyers can communicate, discrimination raises the likelihood of exclusion. Second, when the incumbent seller is unable to discriminate and must make the same offers to the buyers, communication reduces the likelihood of exclusion. Communication also induces mo...

摘要：Aggregate and sectoral comovement are central features of business cycles, so the ability to generate comovement is a natural litmus test for macroeconomic models. But it is a test that most models fail. We propose a untied model that generates aggregate and sectoral comovement in response to contemporaneous and news shocks about fundamentals. The fundamentals that we consider are aggregate and sectoral total factor productivity shocks as well as investment-specific technical change. The model...

摘要：We develop a general equilibrium model in which stock prices of innovative firms exhibit bubbles during technological revolutions. In the model, the average productivity of a new technology is uncertain and subject to learning. During technological revolutions, the nature of this uncertainty changes from idiosyncratic to systematic. The resulting bubbles in stock prices are observable ex post but unpredictable ex ante, and they are most pronounced for technologies characterized by high uncerta...
