In RBC models, “disaster risk shocks” reproduce countercyclical risk premia but generate an increase in consumption along the recession and asset price fall, through their effects on agents' preferences (Gourio, 2012). This paper offers a solution to this puzzle by developing a New Keynesian...

I connect interest rates, risk premia and welfare costs of long-run consumption uncertainty in a setting with Epstein and Zin (1989) preferences. I find that long-run uncertainty can create significant welfare costs even when risk aversion is moderate and the short-run consumption volatility...

We introduce an information-based fragility measure for GMM models that are potentially misspecified and unstable. A large fragility measure signifies a GMM model's lack of internal refutability (weak power of specification tests) and external validity (poor out-of-sample fit). The fragility of...

We find that high macroeconomic uncertainty is associated with greater accumulation of physical capital, despite a reduction in investment and valuations. To reconcile this puzzling evidence, we show that uncertainty predicts lower depreciation and utilization of existing capital, which...

This paper considers the business cycle, asset pricing, and welfare effects of increased risk aversion, while holding intertemporal substitution preferences constant. I show that increasing risk aversion does not significantly affect the relative variabilities and co-movements of aggregate...

The capital asset pricing model (CAPM) receives both criticism and widespread adoption by practitioners and academics as the weighted average cost of capital (WACC) equity component. This study introduces two new costs of equity measures to address CAPM criticisms and provide new perspective on...

The value premium is the empirical observation that low market/book “value” stocks have higher returns than high market/book “growth” stocks. In this paper, we investigate and present evidence for an “equity as a call option hypothesis” for the value premium. Volatility decreases the...

Presentation Slides for "Overconfidence, Arbitrage, and Equilibrium Asset Pricing" This paper offers a model in which asset prices reflect both covariance risk and misperceptions of firmsapos prospects, and in which arbitrageurs trade against mispricing. In equilibrium, expected returns are...

The basic paradigm of asset pricing is in vibrant flux. The purely rational approach is being subsumed by a broader approach based upon the psychology of investors. In this approach, security expected returns are determined by both risk and misvaluation. This survey sketches a framework for...

This paper studies the mismatch between asset managers' performance window and the time average of their benchmark dividend payouts, commonly referred to as duration. Our asset pricing equilibrium mechanism provides the first plausible theoretical foundation for the recent empirical findings...
