We study the competitive equilibria of a two-country endogenous growth model in which the source of growth is the linearity of technology in reproducible inputs. We begin by showing that in a model with no externalities there is a unique equilibrium; however, there are multiple ways in which the...

The open-economy Solow-Swan growth model predicts (1) that growth should be uncorrelated with the ratio of national investment to GDP and (2) instantaneous convergence of GDP per capita across countries. In the presence of capital market imperfections convergence is predicted to occur more...

Three well known facts that characterize exchange rate data are: (a) the high correlation between bilateral nominal and real exchange rates; (b) the high degree of persistence in real exchange rate movements; and (c) the high volatility of real exchange rates. This paper attempts a joint, albeit...

A famous dictum in open economy macroeconomics -- which obtains in the Mundell-Fleming world of sticky prices and perfect capital mobility -- holds that the choice of the optimal exchange rate regime should depend on the type of shock hitting the economy. If shocks are predominantly real, a...

This paper revisits the issue of the optimal exchange rate regime in a flexible price environment. The key innovation is that we analyze this question in the context of environments where only a fraction of agents participate in asset market transactions (i.e., asset markets are segmented)....

The rising current account deficit in the USA has attracted considerable attention in recent years. We use the “business cycle accounting” methodology to identify the principal distortions that have affected the external accounts of the US. In particular, we measure distortions in the...

Recent declines in the U.S. current account and fiscal balances have sparked renewed debate over the twin-deficit hypothesis, which argues that a larger fiscal deficit, through its effect on national saving, leads to an expanded current account deficit. This study reviews international evidence...

In this paper the authors study the economic evolution between 1960 and 1995 of two states in India — Maharashtra and West Bengal. In 1960, West Bengal’s per capita income exceeded that of Maharashtra. By 1995, it had fallen to just 69 percent of Maharashtra’s per capita income. The...
