The impact of uncertainty on investment has attracted considerable attention in the analytical and empirical macroeconomic literature. In theory, however, uncertainty can affect investment through different channels, some of which operate in mutually opposing direction. So, the sigh of its...

Between 1990 and 2001 the Argentine peso appreciated by 80 percent in real terms, and its overvaluation has been singled out as one of the main suspects in the debate on the causes of the Argentina collapse of late 2001. This paper assesses the degree of real misalignment in Argentina over the...

A recent (but rapidly growing) literature has focused on how uncertainty and instability affect the adoption of fixed investment projects. That literature shows that if fixed investment projects are costly or impossible to reverse, uncertainty can become a powerful deterrent to investment. The...

Credibility and transparency are at the core of the current debate about exchange rate regimes. The steady growth in the magnitude and variability of international capital flows has complicated the question of whether to use floating, fixed, or intermediate exchange rate regimes. Emerging market...

The impact of permanent real depreciation on a country's capital stock is uncertain. Whether total capital stock rises or falls depends on how depreciation affects aggregate demand, the real interest rate, and especially the import content of capital goods. In the long run, the capital stock can...

The Argentine crisis has been variously blamed on fiscal imbalances, real overvaluation, and self-fulfilling investor pessimism triggering a capital flow reversal. The authors provide an encompassing assessment of the role of these and other ingredients in the recent macroeconomic collapse. They...

The authors analyze the impact of fiscal policy changes in openeconomies, using a rational expectation framework that nests two prototype economies: a neoclassical full-employment benchmark economy, with intertemporally optimizing consumers and firms and instant clearing of asset, goods, and...

Capital flows to developing countries are small and take mostly the form of loans rather than direct foreign investment. We build a simple model of North-South capital flows that highlights the interplay between diminishing returns, production risk and sovereign risk. This model generates a set...

For the past two decades, Chile has consistently pursued a course of macroeconomic stabilization and deep economic reform. But in recent years, real exchange rate appreciation and persistent moderate inflation have become key concerns for Chilean policymakers, suggesting the need for further...

In the 1990s macroeconomic policies improved in a majority of developing countries, but the growth dividend from such improvement fell short of expectations, and a policy agenda focused on stability turned out to be associated with a multiplicity of financial crises. The authors take a...
