We study optimal transport networks in spatial equilibrium. We develop a framework consisting of a neoclassical trade model with labor mobility in which locations are arranged on a graph. Goods must be shipped through linked locations, and transport costs depend on congestion and on the...

Existing models of contagious currency crises are summarized and surveyed, and it is argued that more weight should be put on political factors. Towards this end, the concept of political contagion introduced, whereby contagion in speculative attacks across currencies arises solely because of...

This essay offers an economic-history perspective of the long struggle towards macroeconomic stability. The paper is a broad analytical overview of major exogenous shocks and shifts in macroeconomic policy and institutions in Israel since the 1977-1985 great inflation through the global...

This paper presents a dynamic stochastic general-equilibrium model with a single friction in all markets: sticky information. In this economy, agents are inattentive because of costs of acquiring, absorbing and processing information, so that the actions of consumers, workers and firms are slow...

In this paper I analyze the nature of external adjustments in current account surplus countries. I ask whether a realignment of world growth rates -- with Japan and Europe growing faster, and the U.S. growing more slowly -- is likely to solve the current situation of global imbalances. The main...

The paper combines insights from the recent research programs on constitutions and economic policy, and on history, institutions and growth. Drawing on cross-sectional as well as panel data, it presents new empirical results showing that the form of democracy (rather than democracy vs....

This paper analyzes two-way interactions between structural reform and macro policy. If structural reforms increase the flexibility of labor markets, they are likely to improve the short-run inflation-unemployment tradeoff, providing an incentive for policymakers to expand aggregate demand....

The 1980s were both the lost decade of growth for much of Latin America and Africa, and the period in which -- through the new growth theory -- macroeconomists returned to the study of growth and development. The new growth theory is production function driven and concerned primarily with steady...

The paper stresses the evolutionary and adaptive experience of Latin American growth between 1950 and 1980, and provides a synthetic view by considering the sources of growth within a simple production framework. Regressions use quinquennial panel data for 18 Latin American countries.They...

As economists increasingly help governments design new policies and regulations, they take on an added responsibility to engage with the details of policy making and, in doing so, to adopt the mindset of a plumber. Plumbers try to predict as well as possible what may work in the real world,...
