Empirical evidence documents substantial persistence in the adjustment process to nominal shocks. Existing open-economy models have failed either to generate interesting dynamics or found that the mechanisms are quantitatively weak. We consider the propagation of nominal shocks in a fully...

The debate on the risks and benefits of the globalisation of international capital markets has focused on the volume and the volatility of the main capital flows ? foreign direct investment (FDI), portfolio investment, and foreign bank lending. Financial transfers in the form of worker...

The globalization of capital and product markets has many implications for economic welfare. Countries can specialize in the production of goods for which they have comparative advantages, and capital is allocated more efficiently. However, one potentially adverse effect of globalization is the...

We analyze the transmission of monetary shocks in a new openeconomy macroeconomics model with one-period nominal contracts and imperfect information. Shocks may have transitory and persistent components, which only through accumulation of information over time becomes known. Responses to shocks...

I measure the welfare gains from eliminating fluctuations in investment in an emerging economy such as Argentina. The estimated welfare effects are an order of magnitude higher than those for the US and arise with moderate degrees of diminishing returns to investment

A puzzle in international macroeconomics is that observed real exchange rates are highly volatile. Standard international real business cycle (IRBC) models cannot reproduce this fact. We show that total factor productivity processes for the United States and the rest of the world are...

Credit constraints that link a private agent's debt to market-determined prices create a systemic credit externality that drives a wedge between competitive and (constrained) socially optimal equilibria, which induces private agents to "overborrow". We quantify the effects of this externality in...

We analyze implications of inflation persistence for business cycle dynamics following terms of trade and risk-premium shocks in a small open economy, under fixed and flexible exchange rate regimes. We show that the country's adjustment paths are slow and cyclical if there is a significant...

This paper studies the convergence process, or lack thereof, of Total Factor Productivity (TFP) for a panel of 13 OECD countries over the period 1979-2007, adding breadth and depth to the convergence debate in the telecommunications industry. TFP growth is examined through the Malmquist Index...
