| Politicians dealing with the "farm problem" sometimes lament that output increases when prices go up and when prices go down. This article presents three possible theoretical explanations. In the first, farmers deplete soil (over-farm) when prices are low and imperfect capital markets prevent borrowing. In the second, farmers in financial stress (low prices) allocate more family labor to farming to meet debt-repayment constraints. In the third, wealth held in farmland tends to decline as prices decline. With decreasing absolute risk aversion, this increases risk aversion which, in extreme cases, causes negative supply response. |

| This article reviews two major approached used in the past for risk analysisthe expected utility approach and the use of safety rulesand endeavors to reconcile their applicability and use in light of the recent nonexpected utility risk literature and working using the mean-Gini coefficient for risk analysis. This leads to the identification of several "reduced form" hypotheses that hold under a variety of theoretical structures and to a discussion of some empirical evidence regarding these hypotheses. The major lesson of recent research of individual behavior under risk is that it is not always consistent with the expected utility approach; in short, there is no generic model for evaluating behavior under risk. |

| People spent $4.350 billion at California golf course facilities in 2000. The total sales, income, and tax impacts on the state economy were $7.872 billion, $4.546 billion, and $1.370 billion in 2000. Direct sales of $4.251 billion directly supported 62,173 jobs, and , through indirect and induced sales impacts, an additional 37,609 jobs. |

| Understanding the allocation of labor between collective and private activities within cooperatives has been an issue of interest for economists and policy makers. This paper extends existing literature by incorporating income uncertainty from both private and collective activities, and by assuming that members are risk averse. The analysis suggests a member's labor response to policy parameters can be decomposed into three components: the mean effect, reflecting the labor response under certainty or risk neutrality; the variance effect, reflecting the response to changes in risk; and the wealth effect, reflecting the response to changes in risk aversion associated with changes in wealth. The analysis demonstrates the labor response may be reversed from... |

| The paper introduces a framework for analyzing the impacts of land control programs on agricultural production under heterogenous land qualities, heterogenous production technologies and imperfect capital markets. It shows that the introduction of diversion programs tends to benefit land owners while harming operators. Moreover, it tends to increase the separation of land ownership and operation and increase concentration among operators. Diversion programs tend to raise land prices lass than proportional to the increases in rental rates. They encourage the adoption of yield increasing technologies, and may also encourage adoption of cost reducing technologies when credit is a binding constraint. Participation in voluntary government programs tends to... |

| The dynamics of biomass growth implies that the yield of irrigated crops depends, in addition to the total amount of water applied, on irrigation scheduling during the growing period. Advanced irrigation technologies relax constraints on irrigation rates and timing, allowing to better adjust irrigation scheduling to the varying needs of the plants along the growing period. Irrigation production functions, then, should include capital (or expenditures on irrigation equipment) in addition to aggregate water. We derive such functions and study their water-capital substitution properties. Implications for water demand and adoption of irrigation technologies are investigated. An empirical application confirms these properties. |

| A driving factor behind pesticide regulation in Canada and the United States is the desire to protect consumers from harmful residues on food. The Food Quality Protection Act (FQPA) was unanimously passed by the U.S. Congress in 1996 and hailed as a landmark piece of pesticide legislation. It amended the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Federal Food, Drug, and Cosmetic Act (FFDCA), and focused on new ways to determine and mitigate the adverse health effects of pesticides. The FQPA is different from past legislation; it is based on the understanding that pesticides can have cumulative effects on people and that policy should be designed to protect the most vulnerable segments of the population. Recent research has... |

| In this paper we present a continuous time optimal control analysis of resistance buildup in agricultural chemicals when the supplier is a monopolist. We compare the monopolistic, competitive and socially optimal solutions after establishing the stability of each equilibrium. The central finding is that with a monopolistic supplier, resistance buildup is lower than socially optimal. This directly opposes the standard result in the resistance literature. This implies that policies to manage resistance should vary with the age of the chemical, with no intervention during the lifetime of a patent and an optimal tax once the patent expires. |
