The dollar is a safe-haven currency and appreciates when global risk goes up. We investigate the dollar’s role for the transmission of global risk to the world economy within a Bayesian proxy structural vectorautoregressive model. We identify global risk shocks using high-frequency asset-price...

We develop a two-country business-cycle model of the US and the rest of the world with dollar dominance in trade invoicing, in cross-border credit, and in safe assets. The interplay between these elements - dollar trinity - rationalizes salient features of the Global Financial Cycle in the data:...

Country-specific business cycle fluctuations are potentially very costly for member states of currency unions because they lack monetary autonomy. The actual costs depend on the extent to which consumption is shielded from these fluctuations and thus on the extent of risk sharing across member...

Interest-rate spreads fluctuate widely across time and countries. We illustrate this on the basis of about 3,100 quarterly observations for 21 advanced and 17 emerging economies since the early 1990s. Prior to the financial crisis, spread fluctuations in advanced economies are an order of...

Interest-rate spreads fluctuate widely across time and countries. We characterize their behavior using some 3,200 quarterly observations for 21 advanced and 17 emerging economies since the early 1990s. Before the financial crisis, spreads are 10 times more volatile in emerging economies than in...

How does global risk impact the world economy? In taking up this question, we focus on the dollar’s role in the international adjustment mechanism. First, we rely on high-frequency surprises in the price of gold to identify the effects of global risk shocks in a Bayesian Proxy VAR model. They...

In this paper we analyze European business cycles before and under EMU. Across the two periods we ?nd 1) a signi?cant decline in real exchange rate volatility, 2) signi?cant changes in cross-country correlations, and 3) the volatility of macroeconomic fundamentals largely un- changed. We develop...

In contrast to the notion that the exchange-rate regime is non-neutral, there is little evidence that EMU has changed the European business cycle. In fact, we find the volatility of macroeconomic fundamentals largely unchanged before and after the introduction of the euro. Exceptions are a...
