| The optimal hedging model has become the standard theoretical model of normative hedging behavior due to its intuitive tradeoff of expected return with risk, its effcient use of information and its easy implementation. In practice, the model can be easily implemented with the Parameter Certainty Equivalent procedure, which substitutes sample estimates for the true but unknown model parameters. But subjective views, which refer to opinions concerning the directions of market returns of the assets involved in hedging decisions, are either completely ignored or handled in an ad hoc and unsatisfactory manner within the optimal hedging model. Given the widespread use of subjective views in hedging practice and the potential economic benefit of selective... |

| We model a futures exchange's clearinghouse as a "bank" holding a portfolio of credit lines available to its clearing members and collateralized with clearing margins or, equivalently, a portfolio of short European put basket options. Consequently, the "bank" model measures the clearinghouse's risk exposure as the sum of the payoff functions of these put options, emphasizing the portfolio diversification and the option-like payoffs. The model is used to assess exchange's clearinghouse's liquidity and credit risk exposure. The model provides exchange clearinghouses and government regulators with a theoretical framework of risk management that systematically integrates clearing margin requirements,credit lines and economic capital. |

| This report presents marketing profiles and loan deficiency payment/marketing loan gain profiles for the advisory services followed by the AgMAS Project for the 2002, 2003 and 2004 soybean crops. Marketing profiles are constructed by plotting the cumulative net amount priced under each program’s set of recommendations throughout the crop year. Loan deficiency payment/marketing loan gain (LDP/MLG) profiles are constructed by plotting the cumulative percentage of the crop on which the LDP/MLG was claimed during the crop year. Marketing profiles provide information to evaluate the style of advisory services in several ways. The percentage of crop priced is a measure of within-crop year price risk. The higher the proportion of a crop priced, the lower the... |

| This report presents marketing profiles and loan deficiency payment/marketing loan gain profiles for the advisory services followed by the AgMAS Project for the 2002, 2003 and 2004 corn crops.

Loan deficiency payment/marketing loan gain (LDP/MLG) profiles are constructed by plotting the cumulative percentage of the crop on which the LDP/MLG was claimed during the crop year.

| The cost of forward contracting corn is estimated with weekly pre-harvest forward bases for seven regions of Illinois from 1975 to 2002. Given the panel structure of the forward basis dataset, we extend Townsend and Brorsen's univariate unit root model for forward bases to a panel unit root model. With the time series of forward bases modeled as unit root processes, the cost of forward contracting is estimated. The empirical results from the estimation show that the cost of forward contracting corn is about 1¢/bushel, one hundred days before the harvest, for all regions in Illinois as a whole. The results also indicates that the cost could vary across regions and that the cost of forward contracting could be substantially higher than that of futures... |

| While the risk premium hypothesis in futures markets has been the subject of a long and continuous controversy, the risk premium hypothesis in forward markets is also of interest among economists. The hypothesis is supported by some theoretical arguments and empirical evidence yet remains an open question. We in this study apply a two-equation regression model similar to those used in (Fama and French (1987} and de Roon et al. (1998) to analyze the risk premiums in forward markets, particularly, using the pre-harvest wheat forward markets in Illinois (1982-2004) and Kansas (1990-2004) as an example. The two-equation regression model consists of a forecasting equation, which uses a forward basis during a pre-harvest period to forecast the spot basis at the... |

| We develop a Bayesian implementation of the standard optimal hedging model to analyze the impact of hedgers' subjective views on their hedging behavior. The results show the subjective views have a substantial impact on hedgers' optimal positions, explaining the large cross-sectional and time series variation of hedging positions in practice. |
