This paper studies the interaction between time preference heterogeneity and precautionary saving in generating both persistent current account imbalance and a stationary equilibrium distribution of wealth across countries. We use numerical techniques to present two sets of results. First, when...

Most analyses of the macroeconomic adjustment required to correct global imbalances ignore net exports of new varieties of goods and services and do not account for firms'net entry in the product market. In this paper we revisit the macroeconomics of trade adjustment in the context of the...

In this paper we present a novel approach to the empirical validation of the intertemporal approach to the current account. We develop a calibrated model highlighting the role of consumption smoothing and capital accumulation in the economic convergence process. After solving the model, we...

This paper analyzes two effects which might have an important impact on a reduction of global external imbalances. These are valuation effects on the one hand and interest rate effects on the other hand. We use a four-region model that is based on the models by Obstfeld and Rogoff (2005) and...

Using a new methodology that allows nonlinearities, we find frequent support for external debt sustainability in a number of Latin American countries. Our findings reverse the results for several countries, obtained with traditional unit-root tests and present a richer framework for evaluating...

A number of developing countries have run large and persistent current account deficits in both the late-1970s/early-1980s and in the early-1990s, raising the issue of whether these persistent imbalances are sustainable. This paper puts forward a notion of current account sustainability and...

The joint dynamics of US net output, consumption, and (valuation-adjusted) foreign assets and liabilities, characterized empirically following Lettau and Ludvigson [2004], is shown to be strikingly consistent with current account theory. While US consumption is virtually insulated from...

Do plans for a monetary union in Europe call for limits on the freedom of the member countries to use fiscal policy? To provide a tentative answer, we simulate the IMF model MULTIMOD, given various shocks, in the case of a European Monetary Union consisting only of France and Germany. The...

Purpose – The purpose of this paper is to determine whether current account imbalances – surpluses or deficits – are “excessive” and hence constitute a valid concern. The second objective is to assess the degree of capital mobility by comparing the variance of the current account...

This paper analyses the determinants of international asset portfolios, using a neoclassical dynamic general equilibrium model with home bias in consumption. For plausible parameter values, the model explains the fact that typical investors hold most of their wealth in domestic assets (portfolio...
