This Paper computes welfare-maximizing monetary and tax policy feedback rules, in a calibrated dynamic general equilibrium model with sticky prices. The government makes exogenous final good purchases, levies a proportional income tax, and issues nominal one-period bonds. A quadratic...

This paper explains three key stylized facts observed in industrialized countries: 1) portfolio holdings are biased towards local equity; 2) international portfolios are long in foreign currency assets and short in domestic currency; 3) the depreciation of a country‘s exchange rate is...

This Paper analyses the welfare effects of monetary policy rules in a quantitative business cycle model of a two-country world. The model features staggered price setting, and shocks to productivity and to the uncovered interest rate parity (UIP) condition. UIP shocks have a sizable negative...

A key dimension of fiscal policy during the financial crisis was massive government support for the banking system. The macroeconomic effects of that support have, so far, received little attention in the literature. This paper fills this gap, using a quantitative dynamic model with a banking...

We study the joint dynamics of foreign capital flows and real activity during the recent boom-bust cycle of the Spanish economy, using a three-country New Keynesian model with credit constrained households and firms, a construction sector and a government. We estimate the model using...

This paper studies the effectiveness of Euro Area (EA) fiscal policy, during the recent financial crisis, using an estimated New Keynesian model with a bank. A key dimension of policy in the crisis was massive government support for banks—that dimension has so far received little attention in...

This paper estimates a two-country model with a global bank, using US and Euro Area (EA) data, and Bayesian methods. The estimated model matches key US and EA business cycle statistics. Empirically, a model version with a bank capital requirement outperforms a structure without such a...

Standard macro models cannot explain why real exchange rates are volatile and disconnected from macro aggregates. Recent research argues that models with persistent growth rate shocks and recursive preferences can solve that puzzle. I show that this result is highly sensitive to the structure of...

This paper develops a novel approach for estimating latent state variables of Dynamic Stochastic General Equilibrium (DSGE) models that are solved using a second-order accurate approximation. I apply the Kalman filter to a state-space representation of the second-order solution based on the...

We estimate a three-country model using 1995-2013 data for Germany, the Rest of the Euro Area (REA) and the Rest of the World (ROW) to analyze the determinants of Germany’s current account surplus after the launch of the Euro. The most important factors driving the German surplus were positive...
