We provide empirical evidence of the causal effects of changes in financial intermediaries' net worth in the aggregate economy. Our strategy identifies financial shocks as high-frequency changes in the market value of intermediaries' net worth in a narrow window around their earnings...

We study the role of financial frictions in determining the allocation of investment and innovation. Empirically, we find that firms are investment-intensive when they have low net worth but become innovation-intensive as they accumulate more net worth. To interpret these findings, we develop an...

We study the role of global financial intermediaries in international lending. We construct a model of the world economy, in which heterogeneous borrowers issue risky securities purchased by financial intermediaries. Aggregate shocks transmit internationally through financial intermediaries' net...

We study how monetary policy affects the asymmetric effects of globalization. To this end, we build an open-economy heterogeneous-agent New Keynesian model (HANK), in which households differ in their income, wealth, and real and financial integration with international markets. We use the model...

In this paper we ask whether tighter monetary and fiscal policies are the right way to face a sudden stop (a sudden curtailment in capital flows) in a typical emerging economy. We develop exogenous measures of fiscal and monetary policy response and conclude that tighter policies are associated...

We empirically characterize episodes of large inflation surges that have been observed worldwide in the last three decades. We document four facts. (1) Inflation following surges tends to be persistent, with the duration of disinflation exceeding that of the initial inflation increase. (2)...
