We use a dynamic general-equilibrium model to study how removing barriers to competition in the nontraded goods sector affects the current account of a small open economy. We show that the expansion of the nontraded sector that results from such a "deregulation shock" is associated with an...

The present value model of the current account has been very popular, as it provides an optimal benchmark to which actual current account series have often been compared. We show why persistence in observed current account data makes the estimated optimal series very sensitive to small-sample...

Incorporating weakly nonseparable preferences into the familiar time-preference model, we emphasize a role of steady-state welfare changes in determining the effect of permanent tariffs on the current account. The effect consists of: a welfare effect, due to steady-state welfare changes, which...

This paper develops a flexible price, two-sector nominal growth model, in order to study the role of the exchange rate regime in capital accumulation (convergence). We adopt a standard model of a small open economy with traded and nontraded goods, and enrich its structure with costly investment...

Both theoretical and operational definitions of current account sustainability show a persistent and fragile current account balance (deficit) for Ghana. This has created a financing gap in the Ghanaian economy, typically filled by capital inflows, in particular aid. Even as Ghana depends to a...

The present paper extends the Obstfeld and Rogoff (2005) framework of current account imbalances by the oil exporting countries as a fourth region. It sets the stage for a variety of analysis that can be conducted within a four-region-setting that accounts for the importance of OPEC as a major...

This paper examines the statistical nature of the persistency of current account balances and its determinants. With the assumption that stationary current account series ensures the long-run budget constraint while countries may experience "local non-stationarity" in current account balances,...

Global current account imbalances are one of the key macroeconomic imbalances that underlie the global financial crisis. The central objective of this paper is to analyze the causes and consequences of global imbalances from the perspective of developing Asia. More specifically, we examine the...

Currently the U.S. is experiencing record budget and current account deficits, a phenomenon familiar from the "Twin Deficits" discussion of the 1980s. In contrast, during the 1990s productivity growth has been identified as the primary cause of the US current account deficit. We suggest a...
