Recent trends suggest the world economy may be tending towards an equilibrium with two distinct trading blocs, each internally integrated, but with significant isolation between the blocs. This paper uses a quantitative theory to explore how far this bifurcation would need to go to pose a threat...

This paper studies how the monetary policy regime affects the relative importance of nominal exchange rates and inflation rates in shaping the response of real exchange rates to shocks. We document two facts about countries with floating exchange rates where monetary policy controls inflation...

We study the roles of globalization and structural change in the evolution of international GDP comovement among industrialized countries over the period 1978-2007. In recent decades, trade integration between advanced economies increased rapidly while average GDP correlations remained stable....

This paper analyzes whether the propensity to secede by subnational regions responds mostly to differences in income per capita or to distinct identities. We explore this question in a quantitative political economy model where people's willingness to finance a public good depends on their...

We develop a simple model to explain why a powerful importer country like the United States may provide political support for international collusive agreements concerning certain commodities (e.g., coffee). This behavior raises questions due to the fact that an importer country should have...

We examine the dynamics of a country's growth, consumption, and sovereign debt, assuming that the government is myopic and wants to maximize short-term, self-interested spending. Surprisingly, government myopia can increase a country's access to external borrowing. In turn, access to borrowing...

Current policies directed at mitigating global warming appear unlikely to prevent temperatures from rising to levels that would trigger a precipitous increase in the costs of climate change. Various attempts at international cooperation to avoid this outcome have failed. Why is this problem so...

We estimate the impact of trade policy uncertainty (TPU) on CES import price indices, focusing on the implications of Britain's exit from the European Union (Brexit). Our analysis reveals that an increase in the probability of Brexit increases U.K. import price indices by raising the prices of...

Governments use their countries' economic strength from existing financial and trade relationships to achieve geopolitical and economic goals. We refer to this practice as geoeconomics. We build a framework based on three core ingredients: input output linkages, limited contract enforceability,...

We formalize the GATT/WTO principle of reciprocity in workhorse quantitative trade models, characterizing reciprocal tariff cuts that hold terms of trade fixed and investigating their labor-market impacts. We provide closed-form expressions mapping reciprocal tariff cuts to labor market...
