We study how the use of judgement or “add-factors” in macroeconomic forecasting may disturb the set of equilibrium outcomes when agents learn using recursive methods. We isolate conditions under which new phenomena, which we call exuberance equilibria, can exist in standard macroeconomic...

This paper proposes a new test of the Protection for Sale (PFS) model by Grossman and Helpman (1994). Unlike existing methods in the literature, our approach does not require any data on political organizations. We formally show that the PFS model predicts that the quantile regression of the...

This paper critically and selectively surveys the literature on protection for sale and discusses directions for future research in this area. It suggests that the standard approach needs to be augmented to provide more compelling tests of this model

In this paper, our aim is to develop an alternative approach to analyzing a macroeconomic model where markets do not clear. Earlier approaches have had difficulties in interpreting effective demand, a key concept in disequilibrium macroeconomics. We propose a new definition of effective demand...

In the first of the two companion papers, we show that the dynamic aspects of the license utilization decision in an uncertain environment, together with the usual policy of rewarding high license utilization with future license allocations. creates four components of the license price. These...

This paper looks at the problem of making multiple lending decisions which affect the supply of the product when the consequences of these lending decisions are interrelated via the effect on the world price of the product. This is termed the 'adding up problem'. It is argued that thinking of...

This paper provides a new heterogeneous firm model for trade where firms differ in their productivity and experience different market demand shocks. The model incorporates variations in trade policy, trade preferences, and the rules of origin needed to obtain them, to reflect real world...

Do minimum wages affect economic outcomes beyond low-skill employment? This paper develops a new model with heterogeneous firms under perfect competition in a Heckscher-Ohlin setting to show that a binding minimum wage raises product prices, encourages substitution away from labor, and creates...

Why do developing countries fail to specialize in products in which they appear to have a comparative advantage? We propose a model of agricultural trade with intermediation that explains how hold-up resulting from poor contracting environments can produce such an outcome. We use the model to...

This paper examines the effects of auctioning quota licenses when market power exists. The overall conclusion is that with oligopolistic markets, quotas, even when set optimally and with quota licenses auctioned off, are - unlikely to dominate free trade. Moreover, auction quotas only strictly...
