The business cycles of advanced economies are synchronized. Standard macro models fail to explain that fact. This paper presents a simple model of a two-country, two-traded good, complete-financial-markets world in which country-specific productivity shocks generate business cycles that are...

This paper analyzes the effects of output volatility shocks and of risk appetite shocks on the dynamics of consumption, trade flows and the real exchange rate, in a two-country world with recursive preferences and complete financial markets. When the risk aversion coefficient exceeds the inverse...

We estimate global inter-firm networks across all major industries from 1981 through 2016 and provide the first empirical tests for both robust (beneficial) and fragile (harmful) network behavior, relating firms' health with global integration. More connected firms are less likely to be in...

Several countries have recently introduced national capital standards exceeding the internationally coordinated Basel III rules, thus suggesting a "race to the top" in capital standards. We study regulatory competition when banks are heterogeneous and give loans to firms that produce output in...

This paper develops a new international trade model with capital market imperfections and endogenous borrowing costs in general equilibrium. Our theoretical model is motivated by new empirical patterns from enterprise survey data of the World Bank. Observing that a substantial fraction of the...

We study how foreign competition affects the composition of investments inside firms. A parsimonious model predicts that firms have an incentive to shift their investments towards more short-term assets when exposed to tougher competition. Using data on expenditures of listed US companies into...

I show that the prices of the internationally traded crypto-currency bitcoin can be used to estimate a currency's unofficial exchange rate and capital controls at a daily interval. Two important bitcoin features are documented: (1) Bitcoin-based exchange rates approximate the behavior, but not...

The first known experiment with an exchange rate band took place in Austria-Hungary between 1896 and 1914. The rationale for introducing this policy rested on precisely those intuitions that the modern literature has emphasized: the band was designed to secure both exchange rate stability and...

I develop a two-country New Keynesian model with capital accumulation and incomplete international asset markets that provides novel insights on the effect that imperfect international risk-sharing has on international business cycles and RER dynamics. I find that business cycles appear similar...

I show that parity realignments alone do not suffice to ensure the long-run sustainability of an exchange rate target zone with imperfect credibility due to the gambler's ruin problem. However, low credibility and frequent realignments can destabilize the exchange rate
