We study different methods of immigration control using a simple model of a congested world. Our main comparison involves quota, the predominant instrument of immigration control, and a proposed system of immigration tolls and emigration subsidies. We show that the equilibrium of the proposed...

We consider a world in which the mode of food production, foraging or agriculture, is endogenous, and in which technology grows exogenously. Using a recent model of coalition formation, we allow individuals to rationally form cooperative communities (bands) of foragers or farmers. At the lowest...

Empirical research on the organization of firms requires that firms be classified on the basis of their control structures. This should be done in a way that can potentially be made operational. It is easy to identify the ultimate controller of a hierarchical organization, and the literature has...

Currently, we have only a limited understanding of how central bank purchases of illiquid assets (“quantitative easing”) affect long-term interest rates, borrowing costs, and the real economy. Since the historical record of quantitative easing is sparse, theoretical work is needed to guide...

Calibration results in Rabin (2000) and Safra and Segal (2008; 2009) suggest that both expected and non-expected utility theories cannot produce non-negligible risk aversion over small stakes without producing implausible risk aversion over large stakes. This paper provides calibration results for...

How does the allocation of scarce jobs and production influence their supply? We present the results of a macroeconomics laboratory experiment that investigates the effects of alternative rationing schemes on economic stability. Participants play the role of consumer-workers who interact in...

Can monetary or fiscal policy stabilize expectations in a liquidity trap? We study expectation formation near the zero lower bound using a learning-to-forecast laboratory experiment. Monetary policy targets inflation around a constant or state-dependent target. Subjects’ expectations...
