Ratios that indicate the statistical significance of a fund’s alpha typically appraise its performance. A growing literature suggests that even in the absence of any ability to predict returns, holding options positions on the benchmark assets or trading frequently can significantly enhance...

Any security’s expected return can be decomposed into its “carry” and its expected price appreciation, where carry is a model-free characteristic that can be observed in advance. While carry has been studied almost exclusively for currencies, we find that carry predicts returns both in the...

While most empirical analysis of prediction markets treats prices of binary options as predictions of the probability of future events, Manski (2004) has recently argued that there is little existing theory supporting this practice. We provide relevant analytic foundations, describing sufficient...

This paper uses a dynamic optimization model to estimate the welfare gains of hedging against commodity price risk for commodity-exporting countries. We show that the introduction of hedging instruments such as futures and options enhances domestic welfare through two channels. First, by...

Theoretically, corporate debt is economically equivalent to safe debt minus a put option on the firm’s assets. We empirically show that indeed portfolios of long Treasuries and short traded put options ("pseudo bonds") closely match the properties of traded corporate bonds. Pseudo bonds...

We study the effect of introducing a new security, such as a non-redundant derivative, on the volatility of stock-market returns. Our analysis uses a standard, continuous time, dynamic, general-equilibrium, full-information, frictionless, Lucas endowment economy where there are two classes of...

Futures markets are a potentially valuable source of information about market expectations. Exploiting this information has proved difficult in practice, because the presence of a timevarying risk premium often renders the futures price a poor measure of the market expectation of the price of...
