This paper argues that the loose monetary policy of two of the world’s most important financial institutions-the US Federal Reserve Board and the European Central Bank-were ultimately responsible for the outburst of global financial crisis of 2008 - 09. Unusually low interest rates in 2001 -...

This paper studies the effects of fiscal policy on GDP, prices and interest rates in 5 OECD countries, using a structural Vector Autoregression approach. Its mains results can be summarized as follows; 1) The effects of fiscal policy on GDP and its components have become substantially weaker in...

We consider the interaction between monetary and fiscal policies, in one country and in a monetary union. In a Nash equilibrium, at least one of the outcomes (output and inflation) are more extreme than the ideal points of both policy authorities. We allow very general stochastic shocks to the...

This paper describes the challenges of globalization in terms of the logic underpinning four distinct policy constraints or "trilemmas" and their interrelationship; in particular the disturbances that arise from capital flows and the difficulties of adjusting monetary policies to a global...

This paper develops a structural macro econometric model of the world economy, disaggregated into forty national economies, to facilitate multilaterally consistent macrofinancial policy, risk and spillover analysis. This panel dynamic stochastic general equilibrium model features a range of...

This paper develops a structural macroeconometric model of the world economy,disaggregated into forty national economies. This panel dynamic stochastic generalequilibrium model features a range of nominal and real rigidities, extensivemacrofinancial linkages, and diverse spillover transmission...

This paper develops a structural macroeconometric model of the world economy, disaggregated into thirty five national economies. This panel unobserved components model encompasses an approximate linear panel dynamic stochastic general equilibrium model featuring a monetary transmission...

This paper quantifies the welfare differences among a monetary union, flexible exchange rates (economic disintegration) and a monetary plus fiscal transfer union (higher economic integration). The vehicle of analysis is a medium-scale New Keynesian DSGE model consisting of two heterogeneous...

We welfare rank various tax-spending policies. The setup is a New Keynesian model of a semi-small open economy featuring sovereign risk premia and loss of monetary policy independence. The model is calibrated to match data from the Italian economy 2001-2011. We compute various optimized...
