| This paper contributes to an evaluation of the performance of ground nuts in drought-prone areas by estimating yield response functions to water from experimental data. They are combined with meteorological data to simulate yields by location. Efficient genotypes are identified by several risk criteria. Genotype rankings based on these risk criteria and simulated yields are different from those based on experimental data and plant scientists' traditional methods of evaluation. |

| Logit regression models are estimated to identify factors affecting decisions to enroll farmland in New York's agricultural districts program and participate in the use-value assessment program. The results suggest that the districts law is consistent with preserving the best farmland at the rural-urban fringe and that the decision to enroll in agricultural districts affects in a recursive fashion the decision to participate in the use-value assessment program. Short-term monetary gains are the overriding considerations in applying for use-value exemptions. This may lead to additional erosion of the tax base via tax preferences for agricultural land. |

| Recent concern among New York dairy farmers has grown regarding potential increases in energy costs as upstate utilities, under mandate from the New York Public Service Commission, move to time-of-use electricity rates. Furthermore, since it is often desirable to maintain relatively fixed intervals between daily milkings, farmers have expressed further concern about their ability to shift electricity consumption from expensive peak period hours to relatively inexpensive off-peak hours. To determine the effects of time-of-use electricity rates on New York dairy farms and to gain a better understanding of methods farmers can adopt to save energy, an empirical model estimating the time-of-day demand for electricity is developed. The parameters from this model... |

| There is a substantial controversy in the economics literature over the magnitude of the expenditure elasticity for food grain in China that is caused, to a large extent, by whether time-series or cross-section data are used in the analysis. A set of reasonable elasticities for a complete demand system is estimated by using a panel of county level data in Guangdong Province for the last ten years. The results show that food grain has a small positive income elasticity, implying that food grain is not an inferior good in China. The reason that consumption per capita has not increased during a period of rapid economic growth in income is that the relative prices of the food and non-food substitutes for food grain have decreased. |

| Agricultural production in the United States, through its intensive use of nitrogen fertilizer, has contributed to nitrate accumulation in groundwater. Concern over this contamination has led to increased public interest in schemes designed to reduce nitrate leachate from agricultural lands. This research compares the costs of alternative regulatory policies in an area of the Com Belt with those for an area of the Northeast. The bioeconomic models of agricultural production and nitrate leaching are used to compare alternative policy instruments. They include soil-specific leaching and productivity characteristics, variables for management response, the dynamic nature of nitrogen movement through the soil, and the stochastic influence of precipitation on... |

| We use the non-tidal Passaic River Watershed as a case study to investigate the size of potential cost savings associated with allowing phosphorus emissions trading amongst Waste Water Treatment Plants (WWTP) to achieve a significant reduction in ambient phosphorus levels. To measure the cost saving, we specify a trading-ratio system similar to that proposed recently by Hung and Shaw (JEEM, 2005) that minimizes the abatement cost of meeting environmental standards. Because there are relatively few potential traders and abatement costs are relatively homogeneous across firms, the cost savings to the 22 municipal waste water treatment plants relative to the base case will be on the order of 7%. We believe that these results fail to support efforts to... |

| Water scarcity is increasingly viewed as the principal constraint limiting agricultural production and human livelihood improvement in the rural areas of many developing countries. Policies that encourage more efficient and equitable water use - including the introduction of incentive-based water pricing systems - are an important challenge. This paper reports the results of a mathematical programming model which was constructed for the El Angel watershed in northern Ecuador with the goal of exploring the effects of several water pricing alternatives. The model incorporates farmers' crop and pasture planting and resource allocation decisions, based on maximizing regional gross margin subject to land, water, labor, seasonal, food security and other... |

| A voluntary program is developed to achieve environmental goals through the self-interested choices of farmers under environmental risk and asymmetric information. Farmers behave to maximize expected net returns, and environmental quality standards are formulated through chance constraints. Because the government may not know each farmer's soil type, policy options must be self-selecting. The model is applied empirically to nitrate leaching and runoff from corn production in three New York regions. Asymmetric information between producers and the government would impose additional cost burdens on society, but these costs are modest in the context of other farm programs. |

| Rapid industrial development and urbanization transfer more and more land away from agricultural production, threatening China’s capability to feed itself. This paper analyzes the determinants of land use by modeling arable land and sown area separately. An inverse U-shaped relationship between land use intensity and industrialization is explored both theoretically and empirically. The findings highlight the conflict between the two policy goals of industrialization and grain self-sufficiency in the end. Several policy recommendations are offered to reconcile the conflict. |

| The major sources of variability in net farm income on New York dairy farms over the past 10 years are identified using Dairy Farm Business Summary records. The most important source of income variability is the fluctuation in milk prices, followed closely by year-to-year variation in the quantity of purchased feeds. These results suggest that forward pricing of milk and feed purchases may be effective risk reduction strategies. Since a few farms have large cull cow sales, probably due to disease or other production problems, new insurance products to insure against disease may be useful to dairy farmers. It appears that older farmers are more successful in engaging in activities that increase diversification and reduce the variability in reductions in... |

| Electric utilities throughout the Nation are experimenting with strategies to reduce total electricity consumption or to alter the timing of electrical power use by their customers. This report focuses on one such strategy, time-of-use (TaU) electric rates, and the likely effect of this pricing option on the New York dairy sector. The purpose of the study is to assess the change in farm electrical energy costs when power is sold to dairymen at higher rates for periods of peak power demand and at substantially lower rates for off-peak periods. This study is based on the results derived from a farm-level, computer decision model which calculates farm energy consumption by major end uses--such as milk cooling and feeding--and by time of day. The model... |
