Research in progress Free for a Fee: The Hidden Cost of Index Fund Investing (Job market paper) Asset Pricing with Garbage (Forthcoming, The Journal of Finance) A new measure of consumption—garbage—is more volatile and more correlated with stocks than the standard measure, NIPA consumption expenditure. A garbage-based CCAPM matches the U.S. equity premium with relative risk aversion of 17 versus 81 and evades the joint equity premium-risk-free rate puzzle. These results carry through to European data. In a cross section of value, size and industry portfolios, garbage growth is priced and drives out NIPA expenditure growth. Wall Street Journal article Internet Appendix Slides The Puzzle of Index Option Returns (With George Constantinides and Jens Jackwerth) We find that the leverage-adjusted returns on S&P 500 index calls and puts are decreasing in their strike-to-price ratio over 1986-2007, contrary to the prediction of the Black-Scholes-Merton model. A large number of factor models fail to explain the cross-section of option returns. Two option-specific factors, the change in the monthly out-of-the-money put volume and the change in the VIX index, have some explanatory power when their premia are estimated from the universe of options but large alphas remain when their premia are estimated from equities.
