This paper studies Ramsey-optimal monetary and fiscal policy in a New Keynesian 2-country open economy framework, which is used to assess how far fiscal policy can substitute for the role of nominal exchange rates within a monetary union. Giving up exchange rate flexibility leads to welfare...

Against the background of the recent housing boom and bust in countries such as Spain and Ireland, we investigate in this paper the macroeconomic consequences of cross-border banking in monetary unions such as the euro area. For this purpose, we incorporate in an otherwise standard two-region...

Several studies have analyzed the trade and output effects of the Transatlantic Trade and Investment Partnership (TTIP) between the United States and the European Union, but our paper is the first attempt to study its welfare effects. We measure the welfare effect of TTIP as the percentage of...

After an expansionary monetary policy shock employment increases and unemployment falls. In standard New Keynesian models the fall in aggregate unemployment does not affect employed workers at all. However, Lüchinger, Meier and Stutzer (2010) found that the risk of unemployment negatively...

We use event study regressions to compare the impact of EU monetary versus fiscal policy announcements on government bond spreads of ten euro member countries. Our motivation is to evaluate which of the two players - the ECB or the EU fiscal level - has been more crucial for the stabilization of...

The development of macroprudential policy tools has been one of the most significant changes in banking regulation in recent years. In this multi-study initiative of the International Banking Research Network (IBRN), researchers from 15 central banks and 2 international organizations use...

How do labor market reforms affect international competitiveness and net foreign assets? To answer this question, we build a two-region RBC model with labor market frictions, idiosyncratic consumption risk, and limited cross-sectional heterogeneity to establish a direct link between labor market...

We show that if business cycles are driven by financial shocks, the interplay between the effective lower bound (ELB) and the costs of external financing can generate an additional supply-side channel, which causes a disconnect between inflation and output. In normal times, factor costs dominate...

When is it optimal for a government to default on its legal repayment obligations? We answer this question for a small open economy with domestic production risk in which contracting frictions make it optimal for the government to finance itself by issuing non-contingent debt. We show that...

Activities of international banks have been at the core of discussions on the causes and effects of the international financial crisis. Yet, we know little about the actual magnitudes and mechanisms for transmission of liquidity shocks through international banks, including the reasons for...
