Monetary rules may have a large effect on the outcome of trade wars if central banks target the CPI inflation rate or more generally changes in the relative price of traded goods. We lay out a two-country open-economy model with sticky prices where countries engage in trade wars. In the presence...

We survey the literature on global capital allocation. We begin by reviewing the rise of cross-border investment, the shift towards portfolio investment, and the literature focusing on aggregate patterns in multilateral and bilateral positions. We then turn to the recent literature that uses...

We develop a general policy analysis framework for an open economy that features nominal rigidities and financial frictions giving rise to endogenous PPP and UIP deviations. The efficient allocation can be implemented with monetary policy closing the output gap and FX interventions eliminating...

Recent theories of exchange rate determination have emphasized limited UIP arbitrage by international financial institutions. New regulations since 2008 have also lead to imperfect CIP arbitrage. We show that under limited CIP arbitrage the exchange rate and CIP deviation are jointly determined...

We develop a model of export-platform foreign direct investment (FDI) in which final goods are produced only with labor and there are no fixed costs of exporting. We derive a simple condition that determines whether an MNE's plants are substitutes or complements. This condition is shaped by the...

We introduce a general quantifiable framework to study the location decisions of multinational firms. In the model, firms choose in which locations to pay the fixed costs of setting up production, taking into account potential complementarities among production locations. The firm's location...

Developing countries employ a very large share of their workforce in agriculture, a sector in which their labor productivity is particularly low. We take a macroeconomic approach to analyze the role of agriculture in development. We construct a new database with systematic measures of inputs and...
