We model residential land use constraints as the outcome of a political economy game between owners of developed and owners of undeveloped land. Land use constraints benefit the former group (via increasing property prices) but hurt the latter (via increasing development costs). More desirable...

This paper makes a case that the global imbalances of the 2000s and the recent global financial crisis are intimately connected. Both have their origins in economic policies followed in a number of countries in the 2000s and in distortions that influenced the transmission of these policies...

It is commonly argued that skilled immigration benefits the destination country through several channels. Yet, only a small group of countries reports to have policies in place aimed at increasing the intake of skilled immigrants. Why? In this paper we analyze the factors that affect a direct...

A study of distortions to agricultural incentives in 18 developing countries during 1960-84, by Krueger, Schiff and Valdés (1988; 1991), found that policies in most of those developing countries were directly or indirectly harming their farmers. Since the mid-1980s there has been a substantial...

A striking feature of many financial crises is the collapse of exports relative to output. In the 2008 financial crisis, real world exports plunged 17 percent while GDP fell 5 percent. This paper examines whether the drying up of trade finance can help explain the large drops in exports relative...

The paper considers the case for an internationally coordinated further fiscal stimulus during the second half of 2009. Although this makes some of the analysis period-specific, most of the issues and principles considered are timeless. For a fiscal stimulus to be both effective there must be...

We study the contribution of the stock of money to the macroeconomic outcomes of the 1990s in Japan using a small scale structural model. Likelihood-based estimates of the parameters are provided and time stabilities of the structural relationships analyzed. Real balances are statistically...

We survey the literature on social networks by putting together the economics, sociological and physics/applied mathematics approaches, showing their similarities and differences. We expose, in particular, the two main ways of modeling network formation. While the physics/applied mathematics...

This paper discusses the place of oligopoly in international trade theory, and argues that it is unsatisfactory to ignore firms altogether, as in perfectly competitive models, or to view large firms as more productive clones of small ones, as in monopolistically competitive models. Doing either...

The debate on trade and growth increasingly focuses on the composition of exports. Exports of more "sophisticated" products appear to be positively correlated with growth, and upgrading the quality of exports is high on the policy agenda of many countries. This study presents evidence suggesting...
