Risk analysis involves gaining deeper insight into the sources of risk, and evaluating whether these risks accurately reflect the views of the portfolio manager. In this paper, we show how to extend standard volatility analytics to shortfall, a measure of extreme risk. Using two examples, we...

I provide an explanation for the puzzle of slow recovery of aggregate real variables from financial crises. My model features a representative investor who finances firms with optimal long-term contracts derived from a moral hazard problem. An increase in uncertainty about firm-productivity...

We show that time-varying risk premium in financial markets can explain a key yet puzzling feature of labor markets: the large differences in unemployment risk across worker age-groups over the business cycle. Our search model features a time-varying risk premium and learning about unobserved...

We present a theory in which limited risk sharing of idiosyncratic labor income risk plays a key role in determining the dynamics of interest rates. Our production-based model relates the crosssectional distribution of labor income risk to observable aggregate labor market variables. Our model...

We provide a theoretical model linking firm characteristics and expected returns. The key ingredient of our model is technological shocks embodied in new capital (IST shocks), which affect the profitability of new investments. Firms' exposure to IST shocks is endogenously determined by the...

We study asset-pricing implications of innovation in a general-equilibrium overlapping- generations economy. Innovation increases the competitive pressure on existing firms and workers, reducing the profits of existing firms and eroding the human capital of older workers. Due to the lack of...
