Returns to Speculators and the Theory of Normal Backwardation

A nonparametric statistical procedure is employed to examine the returns to speculators in wheat, corn, and soybeans futures markets. We find that the theory of normal backwardation is supported. Moreover, the presence of the risk premiums to speculators tends to be more prominent in recent years than in earlier years. We also find that large wheat speculators as a whole possessed some superior forecasting ability. The evidence is inconsistent with the hypothesis that commodity futures prices are unbiased estimates of the corresponding future spot prices.     

Asymmetric Trading Costs Prior to Earnings Announcements: Implications for Price Discovery and Returns

We show that the cost of trading on negative news, relative to positive news, increases before earnings announcements. Our evidence suggests that this asymmetry is due to financial intermediaries reducing their exposure to announcement risks by providing liquidity asymmetrically. This asymmetry creates a predictable upward bias in prices that increases preannouncement, and subsequently reverses, confounding short‐window announcement returns as measures of earnings news and risk premia. These findings provide an alternative explanation for asymmetric return reactions to firms' earnings news, and help explain puzzling prior evidence that announcement risk premia precede the actual announcements. Our study informs methods for research centering on earnings announcements and offers a possible explanation for patterns in returns around anticipated periods of heightened inventory risks, including alternative firm‐level, industry‐level, and macroeconomic information events.

The Long-Lasting Momentum in Weekly Returns

Reversal is the current stylized fact of weekly returns. However, we find that an opposing and long‐lasting continuation in returns follows the well‐documented brief reversal. These subsequent momentum profits are strong enough to offset the initial reversal and to produce a significant momentum effect over the full year following portfolio formation. Thus, ex post, extreme weekly returns are not too extreme. Our findings extend to weekly price movements with and without public news. In addition, there is no relation between news uncertainty and the momentum in 1‐week returns.     

SENIORITY SEATING AT THE ROYAL OPERA HOUSE

This paper examines lotteries and seniority queues as formsof commodity bundling price discrimination. There are good andbad seats, and two types of potential purchasers. Offered thechoice of a high-priced good seat and a moderately-priced bundleof good and bad seats, cutomers self-select into high and lowvaluation types. For single period purchases, the bundle isa lottery over good and bad seats. For repeated purchases, monopolistssuch as the Royal Opera House can do better by setting up aseniority allocation system.
