This article investigates differences in yields on identical Treasury notes and bills and shows that they reflect differences in liquidity (immediacy) risk and taxes. It proposes an empirical measure for differences in the liquidity risk of notes and bills: the volatility of the underlying rate times the ratio of bills' turnover to notes' turnover. Because differential taxes affect sellers but not buyers of bills and notes, the results reject, free of informational problems, the hypothesis that the notes' demand curve is horizonta. Note-bill yield differences also decrease with inventories of notes—the less liquid asset.

This paper examines the effects of the delivery basis risk embedded in nearly all futures contracts on efficiency tests of these markets. Examining soybean futures contracts, we show that delivery basis risk has important implications for market efficiency tests. Assuming no delivery basis risk, the market efficiency hypothesis is rejected. However, futures prices contain significant time-varying expected delivery basis and time-varying expected delivery risk premiums. Once these expected delivery basis and delivery risk premiums are accounted for, the apparent inefficiency is eliminated. Equilibrium spot prices also contain significant time-varying expected delivery risk premiums.

We study a dynamic model where uncertainty about interim output adjustments causes producers to face price, cost and output uncertainty. Stochastically separable production decisions are independent of the producer’s risk preferences and expectations and are based on the prevailing futures price as a certain output price. Conditions under which futures contracts achieve stochastic separation are established. Optimal hedging and maturity structure of futures contracts, equilibrium futures prices, and the effects of futures trading on output are studied. The systematic risk premium depends on the product of the futures beta and the covariance of the market return with production revenues.

[Earlier studies report significant price disparities between futures and forward or spot markets. Examining the Treasury-bill markets, this article demonstrates that differences in market trading structures explain these disparities. Treasury-bill futures rates contain significantly lower liquidity and default premia than do synthetic forward rates. This reflects the functioning of a futures' clearing association and differences between an open-outcry auction futures market and an over-the-counter dealer spot market. The same factors that make futures contracts nonredundant securities also explain the existence, in equilibrium, of price disparities.]

The relation between default‐free interest rates and expected economic growth is substantially stronger than suggested by extant literature. Futures‐implied Treasury bill yield spreads are more highly correlated with future real consumption, investment, and GNP growth than spot spreads. This stronger relation arises because using futures removes a component of the spot term structure that covaries negatively with real economic growth. Treasury forward rates from spot bills contain a premium for the risk that short‐sellers will default. This risk premium is negatively related to expected economic growth.
