This paper documents some previously neglected features of sectoral shares at business cycle frequencies in OECD economies. In particular, we find that the nontraded sector share of output is as volatile as aggregate GDP, and that for most countries, the nontraded sector is distinctly...

A basic prediction of effcient risk-sharing is that relative consumption growth rates across countries or regions should be positively related to real exchange rate growth rates across the same areas. We investigate this hypothesis, employing a newly constructed multi-country and multi-regional...

This paper presents a new numerical method for solving general equilibrium models with many assets. The method can be applied to models where there are heterogeneous agents, time-varying investment opportunity sets, and incomplete markets. It also can be used to study models where the...

International capital flows have increased dramatically since the 1980s, with much of the increase being due to trade in equity and debt markets. Such developments are often attributed to the increased integration of world financial markets. We present a model that allows us to examine how...

What is the relationship between interest rates and the exchange rate? The empirical literature in this area has been inconclusive. We use an optimizing model of a small open economy to rationalize the mixed empirical findings. The model has three key margins. First, higher domestic interest...

This paper develops a view of exchange rate policy as a trade-off between the desire to smooth fluctuations in real exchange rates so as to reduce distortions in consumption allocations, and the need to allow flexibility in the nominal exchange rate so as to facilitate terms of trade adjustment....

Empirical evidence suggests that for many countries, retail prices of traded goods are sticky in national currencies. Movements in exchange rates then cause deviations from the law of one price, and exchange rate ëmisalignmentí, which cannot be corrected by monetary policy alone. This paper...

Countries that specialize in commodity exports often exhibit a correlation between the relevant commodity price and the value of their currency. We explore a natural but little-studied explanation for this correlation. An increase in the commodity price leads to increases in the future values of...

The use of international capital flow controls has become increasingly popular in academic and policy circles. But almost all the recent literature studies the case of a small economy, ignoring the spillover effects of capital controls to the rest of the world. This paper re-examines the case...

This paper develops a welfare-based model of monetary policy in an open economy. We focus on the extent to which monetary policy should be employed in maintaining the exchange rate. The traditional approach maintains that exchange rate flexibility is desirable in the presence of real...
