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,...

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...

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,...

This paper uses a new method to extract technology shocks that excludes these influences, resulting...

This paper considers the implications of habit formation and financial frictions for the propagation of macroeconomic shocks. In a model that is capable of matching asset pricing moments, a short-lived shock that destroys a small fraction of the economy's stock of pledgeable collateral generates...

This paper studies the effects of imperfect risk-sharing between lenders and borrowers on commercial property prices and leverage. The key friction is that agents use different discount rates to evaluate future flows. Eliminating this pecuniary externality generates large reductions in the...

This study augments the neoclassical growth model with a mechanism that creates a novel transmission channel through which financial shocks propagate to the real economy. By affecting agents' ability to finance consumption expenditures, financial frictions create a demand for safe assets that...
