β¦ Synopsis
he lack of consensus on the underlying process as well as the determinants T of futures prices has led a number of researchers to take a variety of positions in developing models of futures contracts. Normal backwardation/normal contango refers to the process in which futures prices are systematically downward/upward biased estimates of expected spot prices over time.' In order.to test the hypothesis, a number of studies have examined the rate of returns on various futures contractsincluding those on agricultural commodities, precious metals, and financial instruments-and reached different conclusions. O'Brien and Schwarz (1982) observed downward biased futures prices for Gold. However, as Wilson (1982) pointed out, they did not delve into the question why the downward bias of futures prices obtained. In general, the observed divergencies, if any, between futures prices and expected spot prices have been often attributed to market inefficiencies.3 'For the controversy over the underlying process of futures prices, see Keynes (1930.

eynes (1923) and Hicks (1939), hypothesized that futures prices are downward biased estimates of expected spot prices. Any empirical study that employs returns on futures contracts is actually a joint test of both the Keynes-Hicks hypothesis and of the assumed model of returns. Models based on the C
ackwardation refers to an excess of the expected (future) spot price over the B current futures price.' Contango is the reverse. Previous tests for backwardationhontango, by Houthakker (1957), Rockwell (19671, and others, have studied ex post (realized) returns. In contrast to the previous procedure
