| In many parts of the U.S., beef cattle production is a large sector of the agricultural economy, yet few of the cattle are stockered; instead the production is focused on cow-calf operations only. Restricting their operation to only the first phase of beef production may be limiting the cattle owners' profit potential. This paper examines the opportunities for operators to earn additional profit from stockering cattle. Using a representative risk-averse producer, a decision set with seven possible marketing strategies is elevated for the optimal decision in a Bayesian framework which allows for price and production risk. We find that in many instances retaining the cattle for stockering is a superior decision when done in conjunction with specific... |

| The level of natural hedge, i.e. the (negative) correlation between price and yield levels, is an important determinant for farmers’ income risks and their demand for risk management instruments. The natural hedge is often approximated with correlations observed at more aggregated levels, e.g. the county level. This induces biases because the natural hedge at the farm-level is smaller than on more aggregated levels. In this paper, we put this idea one step forward and investigate the empirical relationship between price-yield correlations and the underlying crop acreage, using farm-level data for 5 crops in Switzerland. We find that, for instance, a 1% increase in area under maize and intensive barley leads to a change in the correlation by -0.02 and... |

| We link farmland values to climatic, soil, and socioeconomic variables for counties east of the 100th meridian, the historic boundary of agriculture not primarily dependent on irrigation. Degree days, a non-linear transformation of the climatic variables suggested by agronomic experiments as more relevant to crop yield gives an improved fit and increased robustness. Estimated coefficients are consistent with the experimental results. The model is employed to estimate the potential impacts on farmland values for a range of recent warming scenarios. The predictions are very robust and more than 75% of the counties in our sample show a statistically significant effect, ranging from moderate gains to large losses, with losses in the aggregate that can become... |

| The 1996 Farm Bill, now known as the FAIR (Federal Agricultural Improvement and Reform) Act of 1996, has been portrayed as reforming U.S. agricultural policy. Gone are set aside and base acreage controls over farm planting decisions. Gone, too, are deficiency payment programs that provided protection against downward price movements for producers of program commodities. According to conventional wisdom, the FAIR Act provides an environment in which farmers enjoy greater production flexibility, but face much more risk. In fact, careful examination of the FAIR Act innovations leads to the conclusion that no radical changes have been made in food and feed grain agricultural policies, and that it is unlikely that the FAIR Act will cause large changes in crop... |

| When the application of pesticides places selective evolutionary pressure on pest populations, it can be useful to plant refuge areas-crop areas intended to encourage the breeding of pests that are susceptible to the pesticide. Renewed interest in refuge areas has arisen with recent advances in biotechnology and genetically modified (GM) crops. In this paper, we use a simple model of the evolution of pest resistance to characterize the socially optimal refuge strategy for managing pest resistance. We demonstrate some interesting analogies with other models of renewable resource management, such as those of fisheries. Among the analogous results are findings that maintaining what we might call "maximal sustainable susceptibility" is typically not... |

| Using a CGE model for the Balearic Islands, we simulate the effects of an agricultural water market in the farming sector facing reductions in the water endowment. The market lessens the negative effects on farming communities of short-term water restrictions associated with cyclical droughts. However, in scenarios of permanent reductions, such as those envisaged by global warming predictions or those that result from the implementation of the European Water Framework Directive, a water market may aggravate the negative effects of water shortage. Therefore, the paper shows that generalizations cannot be made about the effects of water markets on farming communities. |

| This paper proposes an alternative approach for separating technical change from time-varying technical inefficiency. The approach uses the general index, developed by Baltagi and Griffin (1988), to model technical change along the production function, and a quadratic function of time trend, as in Cornwell, Schmidt and Sickles (1990), to capture the temporal pattern of technical inefficiency. In such a setting, all parameters associated with the rate of technical change and the temporal pattern of technical inefficiency are identified separately. Moreover, the proposed approach is independent of any distributional assumption concerning the one-sided error term associated with technical inefficiency, and can easily be estimated using FGLS. Comparative... |
