I define and provide empirical evidence for an "International Price System" in global trade employing data for thirty-five developed and developing countries. This price system is characterized by two features. First, the overwhelming share of world trade is invoiced in very few currencies, with...

A handful of currencies, especially the US dollar, play a dominant role in international trade. We survey the active theoretical and empirical literature that documents patterns of currency use in global trade, the implications of dominant currencies for international transmission of shocks,...

We show that "preemptive" capital flow management measures (CFM) can reduce emerging markets and developing countries' (EMDE) external finance premia during risk-off shocks, especially for vulnerable countries. Using a panel dataset of 56 EMDEs during 1996-2020 at monthly frequency, we document...

We use micro data collected at the border and at retailers to characterize the effects of recent changes in US trade policy -- particularly the tariffs placed on imports from China -- on importers, consumers, and exporters. We start by documenting that the tariffs were almost fully passed...

We analyze a unique episode in the history of monetary economics, the 2016 Indian "demonetization." This policy made 86% of cash in circulation illegal tender overnight, with new notes gradually introduced over the next several months. We present a model of demonetization where agents hold cash...

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...

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...

We characterize optimal taxation of foreign capital and optimal sovereign debt policy in a small open economy where the government cannot commit to policy and seeks to insure a risk averse domestic constituency. The expected tax on capital is shown to vary with the state of the economy,...
