October 2011Traded and Nontraded Goods Prices, and International Risk Sharing: an Empirical Investigation.
with Giancarlo Corsetti, Francesca Viani: w17501
Accounting for the pervasive evidence of limited international risk sharing is an important hurdle for open-economy models, especially when these are adopted in the analysis of policy trade-offs likely to be affected by imperfections in financial markets. Key to the literature is the evidence, at odds with efficiency, that consumption is relatively high in countries where its international relative price (the real exchange rate) is also high. We reconsider the relation between cross-country consumption differentials and real exchange rates, by decomposing it into two components, reflecting the prices of tradable and nontradable goods, respectively. We document that, as a common pattern among OECD countries, both components tend to contribute to the overall lack of risk sharing, with the tr...
October 2007Optimal Monetary Policy and the Sources of Local-Currency Price Stability
with Giancarlo Corsetti, Sylvain Leduc: w13544
We analyze the policy trade-offs generated by local currency price stability of imports in economies where upstream producers strategically interact with downstream firms selling the final goods to consumers. We study the effects of staggered price setting at the downstream level on the optimal price (and markup) chosen by upstream producers and show that downstream price movements affect the desired markup of upstream producers, magnifying their price response to shocks. We revisit the international dimensions of optimal monetary policy, unveiling an argument in favor of consumer price stability as the main prescription for monetary policy. Since stable consumer prices feed back into a low volatility of markups among upstream producers, this contains inefficient deviations from the law of...
August 2006Productivity, External Balance and Exchange Rates: Evidence on the Transmission Mechanism Among G7 Countries
with Giancarlo Corsetti, Sylvain Leduc: w12483
This paper investigates the international transmission of productivity shocks in a sample of five G7 countries. For each country, using long-run restrictions, we identify shocks that increase permanently domestic labor productivity in manufacturing (our measure of tradables) relative to an aggregate of other industrial countries including the rest of the G7. We find that, consistent with standard theory, these shocks raise relative consumption, deteriorate net exports, and raise the relative price of nontradables --- in full accord with the Harrod-Balassa-Samuelson hypothesis. Moreover, the deterioration of the external account is fairly persistent, especially for the US. The response of the real exchange rate and (our proxy for) the terms of trade differs across countries: while both rela...
