We estimate how durable expenditures respond to government spending shocks at different points in the business cycle using a nonlinear VAR approach that allows for the durable multiplier to vary smoothly with the state of the economy. We find strong evidence that the aggregate durable spending...

We estimate a state-of-the-art DSGE model to study the natural rate of interest in the United States over the last 20 years. The natural rate is highly procyclical, and fell substantially below zero in each of the last three recessions. Although the drop was of comparable magnitude across the...

I develop a highly tractable general equilibrium model in which heterogeneous producers face collateral constraints, and study the effect of financial frictions on capital misallocation and aggregate productivity. My economy is isomorphic to a Solow model but with time-varying TFP. I argue that...

A representative-consumer model with Epstein-Zin-Weil preferences and i.i.d. shocks, including rare disasters, accords with observed equity premia and risk-free rates if the coefficient of relative risk aversion equals 3-4. If the intertemporal elasticity of substitution exceeds one, an increase...

We show that the risk-shock business cycle model of Fernández-Villaverde et al. (2011) must be recalibrated because it underpredicts the targeted business cycle moments by a factor of three once a time aggregation error is corrected. Recalibrating the corrected model for the benchmark case of...

Aggregate and sectoral comovement are central features of business cycles, so the ability to generate comovement is a natural litmus test for macroeconomic models. But it is a test that most models fail. We propose a unified model that generates aggregate and sectoral comovement in response to...

Intangible capital is an important factor of production in modern economies that is generally neglected in business cycle analyses. We demonstrate that intangible capital can have a substantial impact on business cycle dynamics, especially if the intangible is complementary with production...

Intangible capital which relies on essential human inputs, or "organization capital," presents a unique challenge for measurement. Organization capital cannot be fully owned by firms' financiers, because it is partly embodied in key labor inputs. Instead, cash flows must be shared with key...
