摘要：We conduct a field experiment to measure cooperation among groups of recreational fishermen at a privately owned fishing facility. Group earnings are greater when group members catch fewer fish. Consistent with classical economic theory, though in contrast to prior results from laboratory experiments, we find no cooperation. A series of additional treatments identifies causes of the difference. We rule out the subject pool and the laboratory setting as potential causes and identify the type of...

摘要：Most new consumer durable goods experience rapid prices declines and quality improvements, suggesting the importance of modeling dynamics. This paper specifies a dynamic model of consumer preferences for new durable goods with persistently heterogeneous consumer tastes, rational expectations, and repeat purchases over time. We estimate the model on the digital camcorder industry using panel data on prices, sales, and characteristics. We find that the 1-year elasticity in response to a transito...

摘要：A new model of persuasion is presented. A listener first announces and commits to a codex (i.e., a set of conditions). The speaker then presents a (not necessarily true) profile that must satisfy the codex in order for the listener to be persuaded. The speaker is boundedly rational in the sense that his ability to come up with a persuasive profile is limited and depends on the true profile and the content and framing of the codex. The circumstances under which the listener can design a codex t...

摘要：This paper proposes a new mechanism by which country size and international trade affect macroeconomic volatility. We study a model with heterogeneous firms that are subject to idiosyncratic firm-specific shocks, calibrated to data for the 50 largest economies in the world. When the firm size distribution follows a power law with an exponent close to minus one, idiosyncratic shocks to large firms have an impact on aggregate volatility. Smaller countries have fewer firms and, thus, higher volat...
