This paper builds a baseline two-country model of real and monetary transmission in the presence of optimal international price discrimination by firms. Distributing traded goods to consumers requires nontradables, intensive in local labor. Because of distribution services, the price elasticity...

We decompose the correlation between relative consumption and the real exchange rate in its dynamic components at different frequencies. Using multivariate spectral analysis techniques, we show that, at odds with a high degree of risk sharing, in most OECD countries the dynamic correlation tends...

We decompose the Backus-Smith [1993] statistic --- a low or negative correlation between relative consumption and the real exchange rate at odds with a high degree of international risk sharing --- in its dynamic components at different frequencies. Using multivariate spectral analysis...

We decompose the Backus-Smith [1993] statistic -- a low or negative correlation between relative consumption and the real exchange rate at odds with a high degree of international risk sharing -- in its dynamic components at di¤erent frequencies. Using multivariate spectral analysis techniques...

Soverign debt crises may be driven by either self-fulfilling expectations of default or fundamental fiscal stress. This paper studies the mechanisms by which either conventional or unconventional monetary policy can rule out the former. Conventional monetary policy is modeledas a standard choice...

Building on Calvo (1988), we develop a stochastic monetary economy in which government default may be driven by either self-fulfilling expectations or weak fundamentals, and explore conditions under which central banks can rule out the former. We analyze monetary backstops resting on the ability...

Sovereign risk premia in several euro area countries have risen markedly since 2008, driving up credit spreads in the private sector as well. We propose a New Keynesian model of a two-region monetary union that accounts for this “sovereign risk channel.” The model is calibrated to the euro...
