This paper investigates the linkages between the trade sector and the manufacturing sector as a possible source of complementarities generating cumulative processes and apparent increasing returns in manufacturing firms.

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...

Two exceptions to the argument that export promotion offsets import substitution are provided. The first is based on the observation that protection in small open economies produces monopolisation of the domestic market. The second qualification stems from the discretionary and contingent nature...

There exists considerable evidence from educational measurement theorists that constructed-response questions add little new information about student achievement beyond that provided by multiple- choice questions. The purpose of this paper is to view this issue through the eyes of an economist,...

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...
