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 standard New Keynesian open economy environment. We perform the analysis under alternative pricing assumptions—producer or local currency pricing, along with nominal wage stickiness; under alternative asset market structures, and for anticipated and unanticipated devaluations. There are two types of fiscal policies equivalent to an exchange rate devaluation—one, a uniform increase in import tariff and export subsidy, and two, an increase in value-added tax and a uniform reduction in payroll tax. When the devaluations are anticipated, these policies need to be supplemented with a reduction in consumption tax and an increase in income taxes. These policies have zero impact on fiscal revenues. In certain cases equivalence requires in addition a partial default on foreign bond holders. We discuss the issues of implementation of these policies, in particular, under the circumstances of a currency union.

We document the behavior of trade prices during the Great Trade Collapse of 2008–2009 using transaction-level data from the US Bureau of Labor Statistics. First, we find that differentiated manufactures exhibited marked stability in their trade prices during the large decline in their trade volumes. Prices of non-differentiated manufactures, by contrast, declined sharply. Second, while the trade collapse was much steeper among differentiated durable manufacturers than among non-durables, prices in both categories barely changed. Third, despite this lack of movement in average price levels, the frequency and magnitude of price adjustments at the product level noticeably changed with the onset of the crisis.

The closed and open economy literatures work on estimating real rigidities, but in parallel. We bring the two literatures together to shed light on this question. We use international price data and exchange rate shocks to evaluate the importance of real rigidities in price setting. We show that consistent with the presence of real rigidities the response of reset-price inflation to exchange rate shocks depicts significant persistence. Individual import prices, conditional on changing, respond to exchange rate shocks prior to the last price change.

We characterize optimal taxation of foreign capital and optimal sovereign debt policy in a small open economy where the government cannot commit to policy, seeks to insure a risk averse domestic constituency, and is more impatient than the market. Optimal policy generates long-run cycles in both sovereign debt and foreign direct investment in an environment in which the first best capital stock is a constant. The expected tax on capital endogenously varies with the state of the economy and investment is distorted by more in recessions than in booms amplifying the effect of shocks. The government’s lack of commitment induces a negative correlation between investment and the stock of government debt, a "debt overhang" effect. Debt relief is never Pareto improving and cannot affect the long-run level of investment. Further, restricting the government to a balanced budget can eliminate the cyclical distortion of investment.

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 policy. We show, using novel transaction level information on currency and prices for U.S. imports, that even conditional on a price change, there is a large difference in the pass-through of the average good priced in dollars (25%) versus non-dollars (95%). This finding is contrary to the assumption in a large class of models that the currency of pricing is exogenous and is evidence of an important selection effect that results from endogenous currency choice. We describe a model of optimal currency choice in an environment of staggered price setting and show that the empirical evidence strongly supports the model's predictions of the relation between currency choice and pass-through. We further document evidence of significant real rigidities, with the pass-through of dollar pricers increasing above 50% in the long-run. Lastly, we numerically illustrate the currency choice decision in both a Calvo and a menu-cost model with variable mark-ups and imported intermediate inputs and evaluate the ability of these models to match pass-through patterns documented in the data.

We study a small open economy characterized by two empirically important frictions—incomplete financial markets and an inability of the government to commit to policy. We characterize the best sustainable fiscal policy and show that it can amplify and prolong shocks to output. In particular, even when the government is completely benevolent, the government’s credibility not to expropriate capital endogenously varies with the state of the economy and may be "scarcest" during recessions. This increased threat of expropriation depresses investment, prolonging downturns. It is the incompleteness of financial markets and lack of commitment that generate investment cycles even in an environment where first best capital stock is constant.
