The surge in the German current account surplus in the 2000s is often interpreted as the result of efficiency-enhancing structural reforms, especially in the labor market. However, this interpretation is puzzling because the growth rate of the German economy has been one of the lowest in the...

Before the crisis, there were strong arguments for reducing global imbalances. As a result of the crisis, there have been significant changes in saving and investment patterns across the world and imbalances have narrowed considerably. Does this mean that imbalances are a problem of the past?...

In earlier work we documented two episodes in which a sharp fiscal consolidation was associated with a surprisingly large expansion in private domestic demand. In this paper we draw on further evidence to investigate if and when fiscal policy changes can have such non-Keynesian effects. In the...

This paper uses a dynamic optimization model to estimate the welfare gains of hedging against commodity price risk for commodity-exporting countries. We show that the introduction of hedging instruments such as futures and options enhances domestic welfare through two channels. First, by...

This paper presents a model of international portfolios with real exchange rate and non financial risks that accounts for observed levels of equity home bias. A key feature is that investors can trade equities as well as domestic and foreign real bonds. Bonds matter: in equilibrium, investors...

While the impact of exchange rate changes on economic growth has long been an issue of key importance in international macroeconomics, it has received renewed attention in recent years, owing to weaker growth rates and the debate on “currency wars”. However, in spite of its prevalence in the...

This paper proposes a novel international transmission mechanism based on the assumption of deep habits. The term deep habits stands for a preference specification according to which consumers form habits on a good-by-good basis. Under deep habits, firms face more elastic demand functions in...

This paper improves upon the recently developed literature on exits from fixed exchange rate regimes in three ways: 1) It allows for two indicators for post-exit macroeconomic conditions, the change in the exchange rate and the change in the output gap; 2) it tests whether the distinction...

Fluctuations in GDP are more synchronized internationally than fluctuations in consumption, and they remain so even between financially-integrated economies, where the ranking should in theory be the reverse. This Paper shows this happens because correlations in GDP fluctuations rise with...

Recent cross-country studies on the globalization and output-inflation tradeoff correlation find openness has no significant effect on OECD countries. Those studies assume parameter constancy across countries. In this paper, we argue that this assumption does not hold for major industrialized...
