We explore a view of the crisis as a shock to investor sentiment that led to the collapse of a bubble or pyramid scheme in financial markets. We embed this view in a standard model of the financial accelerator and explore its empirical and policy implications. In particular, we show how the...

We study how financial market efficiency affects a measure of diversification of output across industrial sectors borrowed from the portfolio allocation literature. Using data on sector-level value added for a wide cross section of countries and for various levels of disaggregation, we construct...

We identify the effect of financial integration on international business cycle synchronization, by utilizing a confidential database on banks’ bilateral exposure and employing a country-pair panel instrumental variables approach. Countries that become more integrated over time have less...

Frequently, factors other than structural developments in technology and production effi- ciency drive changes in labor productivity in advanced and emerging market and developing economies (EMDEs). This paper uses a new method to extract technology shocks that ex- cludes these in uences,...

We study the aggregate implications of sectoral shocks in a multi-sector New Keynesian model featuring sectoral heterogeneity in price stickiness, sector size, and input-output linkages. We calibrate a 341 sector version of the model to the United States. Both theoretically and empirically,...

This paper studies the long-run evolution of bank risk and its links to the macroeconomy. Using data for 17 advanced economies, we show that the riskiness of bank assets declined materially between 1870 and 2016. But even though bank assets have become safer, the losses on these assets are...

This paper develops a theory of the credit cycle to account for recent evidence that capital is increasingly allocated to inefficiently risky projects over the course of the boom. The model features lenders who sell risk exposure to non-lender investors in order to relax borrowing constraints,...
