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.
