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 worth. The strength of this transmission is governed by the degree of frictions intermediaries face in financing their risky investments. We provide direct empirical evidence on this mechanism showing that around Lehman Brothers' bankruptcy, emerging‐market bonds held by more distressed global banks experienced larger price contractions. A quantitative analysis of the model shows that global financial intermediaries play a relevant role in driving borrowing‐cost and consumption fluctuations in emerging‐market economies, during both debt crises and regular business cycles. The portfolio of financial intermediaries and the distribution of bond holdings in the world economy are key to determine aggregate dynamics.

This paper studies how the rise in US households' participation in equity markets affects the transmission of macroeconomic shocks to the economy. I embed limited participation into a New Keynesian framework for the US economy to analyze the individual and aggregate effects of higher participation. I derive three main results. First, participants are relatively more responsive to shocks than nonparticipants. Second, higher participation reduces the effectiveness of monetary policy. Third, with higher participation the economy becomes less volatile. I contrast key predictions of my model with new micro-level empirical evidence on the response of consumption to monetary policy shocks.
