We show how real and financial frictions amplify the impact of uncertainty shocks. We build a model with real frictions, and find adding financial frictions roughly doubles the impact of uncertainty shocks. Higher uncertainty alongside financial frictions induces the standard real-options...

We study the implications of recent advances in the asset pricing literature on investment, and vice versa in a DSGE model with non-trivial heterogeneity in production units, lumpy investment, and long run productivity risk. We make three contributions. First, for aggregate asset pricing,...

In standard models wages are too volatile and returns too smooth. We make wages sticky through infrequent resetting, resulting in both (i) smoother wages and (ii) volatile returns. Furthermore, the model produces other puzzling features of financial data: (iii) high Sharpe Ratios, (iv) low and...

We question a deep-ingrained doctrine in asset pricing: If an empirical characteristic-return relation is consistent with investor "rationality," the relation must be "explained" by a risk factor model. The investment approach changes the big picture of asset pricing. Factors formed on...

I study the cross sectional variation of stock returns and technological progress using a dynamic equilibrium model with production. In the model, technological progress is endogenously driven by R&D investment and is composed of two parts. One part is product innovation devoted to creating new...
