| Standard models of hedging behavior assume that either hedgers wish to minimize net price variation or they wish to balance variation versus profits. These models treat variation as risk and fail to distinguish between variation that is random and variation that is not random over time. Newer models of decision making differentiate between random and nonrandom variation somewhat, but they inadequately distinguish variation from risk. This paper reviews the distinctions among variation, uncertainty, and risk and calculates optimal hedge ratios for two models addressing the distinction. Empirical optimal hedge ratios typically decline toward zero when variation aversion is included in the models. These results may help explain why hedgers commonly hedge less... |

| Traditionally, estimation of demand systems is predicated on the validity of several axioms of consumer behavior. While such abstractions make empirical work easier, they can also overlook important economic behavior. Because the price of a good does not reflect the total cost of purchase, there is reason to believe that consumer responses to changes in price are not continuous. Utilizing a regime switching model, we show that there are indeed important threshold effects, and that these effects bias elasticity estimates toward zero. |

| Forecasting has been very important in decision making at all levels and sectors of the economy. In agriculture, where the decision environment is characterized by risks and uncertainty largely due to uncertain yields and relatively low price elasticities of demand of most commodities, decision makers require some information about the future and the likelihood of the possible future outcomes. Forecast information serves many users. Farmer's production and marketing decisions, for instance, are often based on some perspective of the likely pattern of price movements over the coming year. Likewise, production prospects for the season are used by market intermediaries in coordinating their resources. Outlook information about production and consumption... |

| The history of starvation in the world is very tightly linked with the history of humanity. The problem of starvation was discussed in 1945 at the Worldwide Constitutional Conference of Food and Agriculture Organization of the United Nations. The main goal of the organization was and remains a food policy for the benefit of all, in order to liberate all people from starvation. Since 1950, there has been a notable decrease in agricultural production per capita in the developing counties in comparison to the needs. In 1972 and 1973, poor harvests created a dramatic situation in many regions of the world and once again it was in the developing countries where people suffered the most. In the Sahel countries, many thousand of lives would have been lost... |

| This article examines the effects of the application of panel data estimation methods on a system of equations with unbalanced panel data. We apply pooled, random-effects, and fixed-effects estimation in three data sets: small, medium, and large farms to examine the relationship between farm size and the elasticity of cotton supply with respect to cotton price. Our results indicate that the adoption of various estimation methods entails different estimated parameters both in terms of their absolute value and in terms of their statistical significance. Additionally, the elasticity of cotton supply with respect to price varies according to farm size. |

| The role of price risk in sow farrowings is investigated by using bivariate ARCH-M and GARCH-M models and a nonparametric kernel estimator. To account for the relevant time horizon of irreversible supply decisions, predictions for mean price and conditional price variance are iterated forward. The empirical results vary markedly in terms of their implications for risk response in hog supply decisions, with the ARCH-M and GARCH-M models suggesting a small and negative risk effect. Estimates of the marginal risk premium also indicate moderate and variable departures from marginal cost pricing in sow farrowing supply decisions. |

| The purpose of this paper is to determine if there have been systematic changes in the characteristics of Douglas-fir stumpage sold on National Forests in the Pacific Northwest that would significantly bias the price of stumpage. Four hedonic methods were used to develop indices of pure price change holding stumpage characteristics constant. None indicated a significant trend in quality over the period 1968 to 1978. Quality differences, however, appeared to play a role in the year-to-year price changes. The advantage and inconveniences of each indexing method and their use for various purposes are discussed. |

| There is a common perception that healthy food costs more than less healthy food. In this study we use a demand model for diet quality, rather than the quantity of food. Since in our data, total daily cost and diet quality are both calculated from the foods chosen, we account for the fact that cost is endogenous. We find that while total daily food cost is statistically significant in relation to diet quality, the degree of association is very small. Hence, it does not appear that cost alone prevents individuals in the United States from purchasing a healthy diet. Other factors such as food culture and environment, health behaviours, and demographics are more important. Our findings suggest that the choice to consume a healthy diet is very complicated. |
