Abstract
We study a model in which policy aims at aggregate price stability. A fiscal imbalance materializes that, if uncorrected, must cause inflation, but the imbalance may get corrected in the future with some probability. By maintaining price stability in the near term, monetary policy can buy time for a correction to take place. The policy gamble may succeed, preserving price and fiscal stability, or fail, leading to a delayed, possibly large jump in the price level. The resulting dynamics resemble the models of a currency crisis following Krugman (1979) and Obstfeld (1986). Like in Obstfeld’s work, multiple equilibria arise naturally: whether or not price stability is preserved may depend on private agents’ expectations. The model can be reinterpreted as a model of partial default on public debt, in which case it is reminiscent of Calvo (1988).

Abstract
How should monetary policy respond to excessive capital in•ows that appreciate the currency and widen the external de•cit? Using the workhorse two-country open-macro model, we derive a quadratic approximation of the utility-based global loss function in incomplete market economies, and solve for the optimal targeting rules under cooperation. The optimal monetary stance is expansionary if the exchange rate pass-through (ERPT) on import prices is complete, contractionary if nominal rigidities attenuate ERPT. Excessive capital in•ows, however, may lead to currency undervaluation instead of overvaluation for some parameter values. The optimal stance is then invariably expansionary to support domestic demand.

Abstract
We confront the notion that flexible rates insulate a country from external disturbances with new evidence on spillovers from euro-area shocks to neighboring countries. We find that in response to euro-area shocks, spillovers are not smaller, and currency movements not significantly larger, in countries that float their currency, relative to those that peg to the euro—the insulation puzzle. Unconditionally, however, currency volatility is significantly higher for floaters. A state-of-the-art open-economy model can fit our conditional evidence on lack of insulation, provided monetary policy targets headline inflation, but only at the cost of missing the unconditional evidence on currency volatility.

Abstract
Focusing on the foreign exchange reaction to macroeconomic announcements, we show that fast trading is positively and significantly correlated with the entropy of the distribution of quoted prices in reaction to news: a larger share of fast trading increases the degree of diversity of quotes in the order book, for given liquidity, order book depth and size of order flows. Exploiting the WM Reuters’ reform of the fixing methodology in February 2015 as a natural experiment, we provide evidence that fast trading raises entropy, rather than reacting to it. While more entropy in quoted prices means noisier information and arguably complicates price discovery from an individual trader’s perspective, we show that, in the aggregate, more entropy actually brings traded prices closer to the random walk hypothesis, and improves indicators of market efficiency and quality of trade execution. We estimate that a 10 percent increase in entropy reduces the negative impact of macro news by over 60% for effective spreads, against over 40% for realized spreads and price impacts. Our findings suggest that the main mechanism by which fast trading may have desirable effects on market performance specifically hinges on enhanced heterogeneity in trading patterns, best captured by entropy.

Abstract
The euro area has been experiencing a prolonged period of weak economic activity and very low inflation. This paper reviews models of business cycle stabilization with an eye to formulating lessons for policy in the euro area. According to standard models, after a large recessionary shock accommodative monetary and fiscal policy together may be necessary to stabilize economic activity and inflation. The paper describes practical ways for the euro area to be able to implement an effective monetary-fiscal policy mix.

Abstract
A central puzzle in international finance is that real exchange rates are volatile and, in stark contradiction to effcient risk-sharing, negatively correlated with cross-country consumption ratios. This paper shows that incomplete asset markets and a low price elasticity of tradables can account quantitatively for these properties of real exchange rates. The low price elasticity stems from distribution services, intensive in local inputs, which drive a wedge between producer and consumer prices and lower the impact of terms-of-trade changes on optimal agents' decisions. Two very different patterns of the international transmission of productivity improvements generate the observed degree of risk-sharing: one associated with a strengthening, the other with a deterioration of the terms of trade and real exchange rate. Evidence on the effect of technology shocks to U.S. manufacturing, identified through long-run restrictions, is found in support of the first transmission pattern, questioning the presumption that terms-of-trade movements foster international risk-pooling.

Abstract
This paper builds a baseline two-country model of real and monetary transmission under optimal international proce discrimination. Distributing traded goods to consumers reuires nontradables; because of distributive trade, the proce elasticity of export demand depends on the exchange rate. Profit-maximizing monopolistic firms drive a wedge between wholesale and retial proces across countries. This entails possibly large deviations from the law of one price and incomplete pass-through on import prices. Yet, consistent with expenditure-switching effects, a nominal repreciation generally worsens the terms of trade. Moreover, the exchange rate and the terms of trade can be more volatile than fundamentals. For plausible ranges of the distribution margin, there can be multiple steady states, whereas large differences in nominal and real exhange rates across equilibria translate into small differences in consumption, employment and the price level. Finally, we show that with competitive goods markets international policy cooperation is redundant even under financial autarky.
