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...

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...

Using a large cross-country income distribution dataset spanning close to 800 country-year observations from industrial and developing countries, the authors show that the size distribution of per capita income is well approximated empirically by a lognormal density. The null hypothesis that per...
