## Abstract When using derivative instruments such as futures to hedge a portfolio of risky assets, the primary objective is to estimate the optimal hedge ratio (OHR). When agents have meanβvariance utility and the futures price follows a martingale, the OHR is equivalent to the minimum variance he

β¦ Synopsis
n practice, commodity hedgers are faced with a fundamental question: what ratio 'However, despite the differences in the estimated hedge ratios, the returns to the hedge portfolios are not significantly different. This occurs despite the greater variability in the return to the portfolio based on the log utility hedge ratio.

This paper investigates the efficiencies of several generalized least squares estimators (GLSEs) in terms of the covariance matrix. Two models are analyzed: a seemingly unrelated regression model and a heteroscedastic model. In both models, we define a class of unbiased GLSEs and show that their cov
