Technology Innovation and Diffusion as Sources of Output and Asset Price Fluctuations
By: Diego A. Comin, Mark Gertler and Ana Maria Santacreu
We develop a model in which innovations in an economy's growth potential are an important driving force of the business cycle. The framework shares the emphasis of the recent "new shock" literature on revisions of beliefs about the future as a source of fluctuations,... View Details

Reputation When Threats and Transfers Are Available
By: Ernesto Dal Bo, Pedro Dal Bo and Rafael Di Tella
We present a model where a long-run player is allowed to use both money transfers and threats to influence the decisions of a sequence of short-run players. We show that threats might be used credibly (even in arbitrarily short repeated games) by a long-lived player... View Details

Using Models to Persuade
By: Joshua Schwartzstein and Adi Sunderam
We present a framework where "model persuaders" influence receivers’ beliefs by proposing models that organize past data to make predictions. Receivers are assumed to find models more compelling when they better explain the data, fixing receivers’ prior beliefs. Model... View Details

Input Constraints and the Efficiency of Entry: Lessons from Cardiac Surgery
By: David M. Cutler, Robert S. Huckman and Jonathan T. Kolstad
Prior studies suggest that, with elastically supplied inputs, free entry may lead to an inefficiently high number of firms in equilibrium. Under input scarcity, however, the welfare loss from free entry is reduced. Further, free entry may increase use of high-quality... View Details
