Description: This dissertation consists of three essays on cross-sectional anomalies in asset pricing. The first essay, co-written with Jakub W. Jurek, derives and fully characterizes the optimal dynamic strategy for a risk-averse investor with access to a mean-reverting mispricing. We show theoretically that intertemporal hedging demands play an important role in the optimal strategy, that there exists a bound outside of which further divergence in the mispricing causes the investor to unwind her position, and that performance-related fund flows tend to increase the arbitrageur's risk aversion. Empirically, we show that this optimal strategy delivers a significant improvement in Sharpe ratio and welfare relative to a simple threshold rule when applied to Siamese twin shares. The second essay explores whether one of the oldest known violations of CAPM--the value effect--can be rationalized by recently developed models of production-based asset pricing. These models rely on irreversible investment and cross-sectional heterogeneity in firm productivity to explain differences in expected returns, arguing that high productivity firms have lower required returns because they can cut back on investment and raise dividends in bad times. I show empirically that these models generate counterfactual predictions and thus do not provide a satisfactory resolution of the value effect.

The third essay investigates whether one can construct a trading strategy by using industry-specific performance metrics. Firms in the retail and restaurant sectors can grow either by adding new locations or by increasing same-store sales, and investors may not always fully differentiate between the two types of revenue growth. Consistent with this hypothesis, I show that same-store sales growth forecasts equity returns in the cross-section, that it generates significant spreads in portfolio alphas, and that it forecasts future profitability.
