Business cycle correlations are state-dependent and higher in recessions than in expansions. In this paper, I suggest a mechanism to explain why this is the case. For this purpose, I build an international real business cycle model with occasionally binding constraints on capacity utilization...

Modern DSGE models are microfounded and have deep parameters that should be invariant to changes in economic policy, so in principle they are not subject to the Lucas critique. But the literature has already established that misspecification issues also cause parameter instability after policy...

This paper describes a paradox of global thrift. Consider a world in which interest rates are low and monetary policy is constrained by the zero lower bound. Now imagine that governments implement prudential financial and fiscal policies to stabilize the economy. We show that these policies,...

High unemployment and fiscal austerity during the Great Recession have led to significant migration outfl ows in those European countries that suffered a deep deterioration of their economy, Greece being the most obvious case. This paper introduces endogenous migration in a small open economy...

We study simple fiscal rules for stabilizing the government debt level in response to asymmetric demand shocks in a country that belongs to a currency union. We compare debt stabilization through tax rate adjustments with debt stabilization through expenditure changes. While rapid and flexible...

We measure the time-varying strength of macro-financial linkages within and across the US and euro area economies by employing a large set of information for each region. In doing so, we rely on factor models with drifting parameters where real and financial cycles are extracted, and shocks are...

To analyze the international transmission of business cycle fluctuations, we propose a new multilevel dynamic factor model with a block structure that (i) does not restrict the factors to being orthogonal and (ii) mixes data sampled at quarterly and monthly frequencies. By means of Monte Carlo...

Spain's public finances have been under significant stress during the crisis, despite pre-crisis fiscal surpluses and low levels of public debt. The impact of the crisis and an initial phase of counter-cyclical activism exacerbated the existing (structural) fiscal vulnerabilities. To correct the...

This paper shows that heterogeneity in bank capitalization ratios plays a crucial role in the transmission of monetary policy to bank lending. First, I offer new empirical evidence on how banks’ lending responses to monetary policy shocks depend on their capitalization ratios. Highly...

Unemployment in Europe is not only “too high”, it is also too different across countries that belong to a monetary union. In this paper we i) document this increasing heterogeneity, ii) try to explain it and iii) draw from our diagnosis indications as to the appropriate set of policies to...
