However, empirical evidence indicates that the futures markets are highly volatile and inefficient. The study is directed at examining the relationship between futures price deviation and liquidity. Based on Cornell and French’s (1983) cost of carry model, we calculated price deviation between fair prices and actual settlement prices of TAIEX futures, and then conducted a generalized autoregressive conditional heteroscedasticity (GARCH) model fits on two important signals of market liquidity, trade volumes and open interest volumes. The empirical findings indicate that price deviations are significantly related to market liquidity, in terms of trading volumes and open interest volumes, as well as the spreads of past periods. It is found that price deviations are relatively large at the early phase of futures contracts. As arbitrage traders start to come into the market over time, the increases in market liquidity tend to eliminate price deviations. The implication is that TAIEX futures are relatively inefficient for the futures with longer expiration date, compared to their counterparts with shorter expiration date.
