    A survey of 459 ranchers, 56 local decision makers, and 50 public land managers (565 total) was conducted to evaluate managerial, institutional, and social factors that may affect the rate and extent of implementation of various leafy spurge (Euphorbia esula L.) controls. The study focused on a five-county region in Montana, North Dakota, South Dakota, and Wyoming. The questionnaire focused on weed management in general and specifically on the perceptions and attitudes of ranchers, land managers, and local decision makers who have been directly and indirectly affected by leafy spurge.

    Net farm income for all representative farms except small size and low profit farms in 2007 will be higher than in 1998. Net farm income for small and low profit farms will remain the same and decrease, respectively, for the forecasting period. Cropland prices are projected to fall in all regions of North Dakota after having peaked in 1997. Cash rental rates are projected to follow cropland prices. Debt-to-asset ratios for most farms fall across the forecast period. Debt-to-asset ratios for the low profit and small size farms are higher than those for large and high profit farms.

    The real-estate market is "where" a multiplicity of economic, cultural, social and demographic factors are synthesised with respect to choices regarding the qualitative and locational aspects of a property.

    Many land use conflicts are characterized by negative impacts whose severity declines with distance. This paper demonstrates how these "edge effects externalities" may contribute to sub-optimal patterns and scale of land use, therefore providing a strengthened rationale for coordinated land use planning.

    The depreciation rate for capital assets may have endogenous and exogenous components. Change in the exogenous component depends on technological change and/or environmental factors, shifts the production function, and independently affects profitability and investment. Change in the endogenous component does not. These hypotheses are tested using data on Uruguayan grass-legume pastures.

    Today, there are only about 15,000 black farmers in the United States. Declining by 98 percent since 1920, black farmers have suffered losses attributable to public policy, economic pressures, and racial oppression. All of these factors must be addressed if African-American farmers are to survive. In this paper, we use Census of Agriculture data and a follow-on survey in one Mississippi Delta county to review the current situation of black farmers.

    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.
