We characterize fiscal and monetary policy in a monetary union with the potential for rollover crises in sovereign debt markets. Member-country fiscal authorities lack commitment to repay their debt and choose fiscal policy independently. A common monetary authority chooses inflation for the...

We propose a continuous time model of nominal debt and investigate the role of inflation credibility in the potential for self-fulfilling debt crises. Inflation is costly, but reduces the real value of outstanding debt without the full punishment of default. With high inflation credibility,...

We show that even when the exchange rate cannot be devalued, a small set of conventional fiscal instruments can robustly replicate the real allocations attained under a nominal exchange rate devaluation in a dynamic New Keynesian open economy environment. We perform the analysis under...

We empirically characterize the mechanics of trade adjustment during the Argen- tine crisis using detailed transaction-level customs data covering the universe of import transactions during 1996-2008. Though imports collapsed by nearly 70 percent from 2000-2002, the entry and exit of firms or...

We provide a rationale for the observed pro-cyclicality of tax policies in emerging markets and present a novel mechanism through which tax policy amplifies the business cycle. Our explanation relies on two features of emerging markets: limited access to financial markets and limited commitment...

World capital markets have experienced large scale sovereign defaults on a number of occasions, the most recent being Argentina's default in 2002. In this paper we develop a quantitative model of debt and default in a small open economy. We use this model to match four empirical regularities...

A common finding across empirical studies of price adjustment is that there is large heterogeneity in the frequency of price adjustment. However, there is little evidence of how distant prices are from the desired flexible price. Without this evidence, it is difficult to discern what the...

A central assumption of open economy macro models with nominal rigidities relates to the currency in which goods are priced, whether there is so-called producer currency pricing or local currency pricing. This has important implications for exchange rate pass-through and optimal exchange rate...

The closed and open economy literatures work on evaluating the role of real rigidities, but in parallel. This paper brings the two literatures together. We use international price data and exchange rate shocks to evaluate the importance of real rigidities in price setting. We show that...

To what extent do national borders and national currencies impose costs that segment markets across countries? To answer this question we use a dataset with product level retail prices and wholesale costs for a large grocery chain with stores in the U.S. and Canada. We develop a model of pricing...
