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,...

We decompose the correlation between relative consumption and the real exchange rate into its dynamic components at different frequencies. Using multivariate spectral analysis techniques we show that, at odds with a high degree of risk-sharing, in most OECD countries the dynamic correlation...

This paper studies monetary and fiscal policy interactions in a two country model, where taxes on firms’ sales are optimally chosen and the monetary policy is set cooperatively. It turns out that in a two country setting non-cooperative fiscal policy makers have an incentive to change taxes on...

After decades using monetary aggregates as the main instrument of monetary policy and having different varieties of crawling peg exchange rate regimes, Colombia adopted a full-fledged inflation-targeting (IT) regime in 1999, with inflation as the nominal anchor, a floating exchange rate, and the...

In this paper we study the effect of monetary policy shocks on commodity prices. While most of the literature has found that expansionary shocks have a positive effect on aggregate price indices, we study the effect on individual prices of a sample of four commodities. This set of commodity...

This paper develops the "identified VAR" models of France and Spain with German monetary variables to identify monetary policy shocks during the period when the exchange rate is controlled mostly by the ERM. Different identifying assumptions on the contemporaneous policy interactions are...

The sudden collapse of oil prices poses a challenge to inflation targeting central banks in oil exporting economies. This paper illustrates that challenge and conducts a quantitative assessment of the impact of permanent changes in oil prices in a small and open economy, in which oil represents...

In this document we lay out the microeconomic foundations of a dynamic stochastic general equilibrium model designed to forecast and to advice monetary policy authorities in Colombia. The model is called Policy Analysis Tool Applied to Colombian Needs (PATACON). In companion documents we present...

I provide a framework for understanding debt deleveraging in a group of financially integrated countries. During an episode of international deleveraging world consumption demand is depressed and the world interest rate is low, reflecting a high propensity to save. If exchange rates are allowed...

We study the gains from increased wage flexibility and their dependence on exchange rate policy, using a small open economy model with staggered price and wage setting. Two results stand out: (i) the impact of wage adjustments on employment is smaller the more the central bank seeks to stabilize...
