    A programming model is used to assess the welfare effects of regional and practice specifications contained in New York State's Draft Conservation Reserve Enhancement Program (CREP) proposal. Net social benefits are nearly 75% lower than options that explicitly account for opportunity costs of production, environmental benefits, and participation response functions.Keywords: benefit cost analysis, conservation programs, participation, linear programming

    Genetically modified (GM) cotton varieties have changed many aspects of cotton production in the United States. The advent of GM varieties has fueled the ongoing trend of increasing farm size and fewer farmers. Mississippi is no exception to this trend. The rapid adoption of GM cotton varieties in Mississippi has allowed some producers to increase the acreage of their farming operation. This study analyses the impact of GM varieties on relative profitability over certain types of land tenure arrangements.

    Substantial increases in farmland demand in sub-urbanization have had profound effects on agriculture and produced a surge in farmland values. With escalating land values, farmland can take on the characteristics of a speculative asset and farmland owners may be more responsive to the investment value of farmland than the productive value. Speculation has been shown to have a significant impact on the agricultural production decisions of farms, and may encourage farmers to curtail capital investments and prematurely idle productive farmland.

    The rapid change in the character of land use in traditional agricultural regions of the Midwest has led to public concern in recent years. As a result, policy makers have attempted to forge novel ways to cope with problems associated with loss of farmland and the encroachment of urban/suburban sprawl. Some of the policies that have been implemented or suggested in a number of jurisdictions include purchase of development right programs, impact fees, agricultural zoning, and preferred tax treatment for agricultural land uses, among others.

    We apply two innovative econometric approaches to crop trials data to examine effects of rotations and fertilizer use on dynamics of soil quality and corn yields. First, we develop a random coefficients model of yield responses to nitrogen fertilizer and rotations to evaluate both short- and long-run substitutability of N fertilizer for rotation. Second, we construct a dynamic structural model to explicitly recover an indirect but general measure of soil quality. The results yield insights about optimal soil-conserving investments under asymmetric information.

    The levels and risk-free nature of rice market transition payments associated with the FAIR Act of 1996 have encouraged many rice landowners to reconsider their tenure contracts. A methodology for comparing landowners' decision to "self-operate" versus "rent to a tenant" is presented.

    This paper explores the extent to which preference asymmetries occur in Likert-scale indicators of support or opposition to rural land use policies, and implications for methods used to model policy support. Data are drawn from responses to the Rhode Island Rural Land Use Survey.

    This paper presents hedonic analyses designed to estimate the real estate premium from improved access to a regional greenway system in three distinct counties. The hypothesis is tested that unobservable factors relating to the overall economic structure of each county influence how and to what extent access to open space is effectively capitalized into residential sales prices.

    It appears to be widely believed that returns on low quality land are more variable than on high quality land. Using Ricardian rent as the measure of returns and sensitivity to output price as the measure of volatility, we investigate this null hypothesis for three different measures of quality. These are proximity to market, output productivity, and cost efficiency. In all cases, we identify precise conditions on the production technology such that rental volatility varies in a monotone manner with land quality.
