THE EFFECTS OF TIME-OF-USE ELECTRICITY RATES ON NEW YORK DAIRY FARMS AgEcon
Schenkel, Mark; Boisvert, Richard N..
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...

Does Participation in the Conservation Reserve Program and Off-Farm Work Affect the Level and Distribution of Farm Household Incomes? AgEcon
Boisvert, Richard N.; Chang, Hung-Hao.
Using a national survey of U.S farm households, this paper investigates the interrelationship among the decisions to work off the farm by the operator and the spouse, and participation in the Conservation Reserve Program (CRP). The effects of these three decisions on farm household income are also examined. By estimating a heteroscedastic household income function, we identify the effects of participating in these activities on the average level of farm household income and its variation within each sub-group of farms involved in the several combinations of activities. Our empirical results support the hypothesis that participation in the CRP and decisions to work off the farm by the operator and the spouse are made jointly rather than independently. The...

Achieving Environmental Objectives Under Reduced Domestic Agricultural Support and Trade Liberalization: An Empirical Application to Taiwan AgEcon
Chang, Hung-Hao; Boisvert, Richard N.; Blandford, David.
We focus on rice policy reform required for Taiwan's admission to the WTO, and examine the effects, theoretically and empirically, of the re-instrumentation of domestic policy needed to achieve environmental objectives when both positive and negative environmental externalities exist. Policies that treat non-commodity attributes in agriculture as secondary to existing aims, such as income support, are unlikely to result in the desired supplies of environmental goods. Those supplies can be achieved at lower government and social costs using policy instruments to achieve environmental goals directly. Results are relatively insensitive to the social values assigned to environmental goods.

Explaining Changes in the Distribution of Annual Dairy Farm Income over Time AgEcon
Hung-Hao, Chang; Boisvert, Richard N.; Tauer, Loren W..
This paper identifies factors affecting the distribution of farm income among dairy producers over time. Using data from participants in Cornell's Dairy Farm Record Program, we decompose differences of farm income distributions into those due to: differences in means of observable farm characteristics, differential marginal effects of characteristics and unobserved random error. The distribution of farm income is affected by factors reflecting the operators' experience and investment in human capital and indicators of management efficiency and level of capital investment. The marked changes in marginal contributions of these factors explain most of the total change in the distribution of income.

Participation in the Conservation Reserve Program and Off-Farm Work: Implications for Farm and Farm Household Productivity AgEcon
Chang, Hung-Hao; Boisvert, Richard N..
Using a national survey of U.S farm households, we investigate the interrelationship between participation in the Conservation Reserve Program (CRP) and the decision to work off the farm. We go on examine the effects of these two decisions on farm and farm household efficiency and productivity by estimating stochastic frontier productions for farm output and multiple output-orientated distance functions that consider income from agricultural sales, the CRP and off-farm work as outputs of the farm household. We control for the effects of self selection in estimating both the frontier production and distance functions. It appears that operators'’ decisions to work off the farm have led to significant improvements in household resource allocation between...

Explaining Participation in the Conservation Reserve Program and its Effects on Farm Productivity and Efficiency AgEcon
Boisvert, Richard N.; Chang, Hung-Hao.
Using a three-stage sample selection model, we identify factors affecting the probability and level of participation in CRP. Statistical tests support hypotheses that off-farm work and participation in other farm programs are exogenous to the CRP decision. We compare the relative technical and scale efficiencies for CRP participants and non-participants.

Potential Cost Savings from Discharge Permit Trading to meet TDMLs for Phosphorus in the Passic River Watershed AgEcon
Sado, Yukako; Boisvert, Richard N.; Poe, Gregory L..
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...

BIOECONOMICS OF REGULATING NITRATES IN GROUNDWATER: TAXES, QUANTITY RESTRICTIONS, AND POLLUTION PERMITS AgEcon
Thomas, Arthur C.; Boisvert, Richard N..
Soil specific, chance constrained, dynamic models of agricultural production and nitrate leaching are developed to assess the impacts of nitrogen fertilizer taxes, quantity restrictions on fertilizer or leachate, and leachate permits. A programming model uses the solutions of these bioeconomic models to determine regional impacts of the regulations.

Rural Utilities Service's Water and Waste Disposal Loan and Grant Program and its Contribution to Small Public Water System Improvements in New York State AgEcon
Schmit, Todd M.; Boisvert, Richard N..
TIrroughout the debate over re-authorization of the Safe Drinking Water Act (SDWA), it has been clear that members of both Houses of Congress are keenly aware of the financial burden facing the owners of small water systems in their efforts to comply with the 1986 and future amendments to the SDWA. The most reliable source of funds for drinking water and wastewater improvements for small systems has been the Water and Waste Disposal Loan and Grant Program administered through the Rural Utilities Service (RUS) of the USDA's Rural Development mission area. This report provides some background of the RUS loan and grant program. Specific attention is directed towards New York's Rural Development efforts where we develop small system cost models related to...

MEASURING THE RISKS OF NEW YORK DAIRY FARMERS AgEcon
Schmit, Todd M.; Boisvert, Richard N.; Tauer, Loren W..
Decomposition methods suggest major contributors to variability in returns to New York dairy farms are purchased feed quantities and milk production; milk price variability contributes substantially less. Decomposing the Gini measure of income inequality indicates that milk revenues and purchased feed expenditures contribute most to farm return inequality over time.

VALIDATING OPERATIONAL FOOD SECURITY INDICATORS AGAINST A DYNAMIC BENCHMARK AgEcon
Christiaensen, Luc J.M.; Boisvert, Richard N..
Food security indicators used in practice are static in nature, thereby foregoing the key dimension of food security. This study develops an explicitly forward-looking food insecurity indicator and relative to this dynamic benchmark, we evaluate the performance of three readily available indicators: an agricultural production, a dietary diversity, and a coping strategy index. Calculation of our "gold standard" indicator, using panel data of 274 households from Mali, shows that neglecting the future may lead to substantial underestimation of a population's food insecurity. However, when compared to our "gold standard", the alternative indicators all identify most of the food insecure, with the coping strategy index displaying the most predictive power....

The Implications of Geographic Heterogeneity for Multifunctional Rice Policy in Taiwan AgEcon
Chang, Hung-Hao; Boisvert, Richard N.; Blandford, David.
Through empirical simulations of the Taiwanese rice market, we estimate the effects of agricultural policies designed to ensure optimal levels of two multifunctional outputs, groundwater recharge and methane emissions. The settings of policy instruments differ by region to reflect land quality and the conditions of the aquifers. The effects on rice production, resource allocation, and returns to farm assets also differ. Welfare gains are highest if transboundary costs of methane emissions are taken into account. National payments set as a weighted average of optimal regional payments may result in similar welfare gains at lower administrative costs. The costs of assistance measures to help farmers adapt to the impact of lower asset values are shown to be...

NON-TRADE CONCERNS AND DOMESTIC/INTERNATIONAL POLICY CHOICE AgEcon
Blandford, David; Boisvert, Richard N..
In recent years increased emphasis has been placed on a range of "non-trade" concerns and their implications for the move towards freer trade. We review the basis of several of these concerns, focusing particularly on multifunctionality. The simple view of a fixed proportions relationship between agricultural production and non-commodity outputs, such as landscape amenities, is shown to be untenable. Nevertheless, policies to internalize the effects of multiple externalities and public goods must be selected jointly to account for any interrelationships among them, and/or the market goods from agricultural production. We argue that this requires a shift away from traditional agricultural policies with their commodity orientation, towards a new policy...

INDUSTRIALIZATION, URBANIZATION, AND LAND USE IN CHINA AgEcon
Zhang, Xiaobo; Mount, Timothy D.; Boisvert, Richard N..
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.

DESIGNING NONPOINT SOURCE POLLUTION POLICIES WITH LIMITED INFORMATION ABOUT BOTH RISK ATTITUDES AND PRODUCTION TECHNOLOGY AgEcon
Peterson, Jeffrey M.; Boisvert, Richard N..
A pollution reduction program is designed where information about both technology and risk preferences is asymmetric. Program costs and the distribution of payments depend on the amount of information known to the policy maker. Empirically testable conditions for self-selection are derived; the method is applied to reducing nitrate contamination.

Optimal Voluntary "Green" Payment Programs To Limit Nitrate Contamination Under Price and Yield Risk AgEcon
Peterson, Jeffrey M.; Boisvert, Richard N..
A model of a voluntary "green" payment program is developed to control nitrate leaching and runoff from corn production in New York. The program achieves environmental goals through self-interested choices of farmers, grouped by the productive and environmental characteristics of soils. It considers randomness in prict}~, production, and environmental damage. Farmers are assumed to maximize expected utility subject to chance constraints on severe levels of nitrate contamination. This program compensates farmers for applying environmentally safe levels of nitrogen fertilizer. If information is symmetric, program participation conditions require that the post-policy expected utility is at least as large as pre-policy expected utility. Under asymmetric...

Are Farmers' Decisions to Work off the Farm and Participate in the Conservation Reserve Program Independent, Joint or Sequential? AgEcon
Chang, Hung-Hao; Boisvert, Richard N..
There is statistical evidence that decisions to participate in CRP and work off-farm are made simultaneously. Characteristics of households, farm operations other farm programs, and the local economies affect both decisions; some factors affect only one. Policy changes that affect one decision may affect another directly and/or indirectly.

U.S. Policy for Agricultural Adjustment AgEcon
Blandford, David; Boisvert, Richard N..
Domestic and international factors may combine to stimulate change in US agricultural policies and reductions in the costs of support. This would create additional pressures for economic adjustment in the sector. Current U.S. agricultural policies are not oriented to facilitating such adjustment. A trade adjustment program for agriculture, recently included as part of U.S. trade legislation, continues the traditional focus on income support. We discuss the reorientation of existing agricultural policies to facilitate economic adjustment resulting from the reform of domestic agricultural and trade policies. We focus on measures to address three key areas: 1. asset value reductions; 2. human capital issues; and 3. persistent poverty. Estimates of costs...

ACCOUNTING FOR THE IMPORTANCE OF NONFARM INCOME ON FARM FAMILY INCOME INEQUALITY IN NEW YORK AgEcon
Boisvert, Richard N.; Ranney, Christine K..
As the proportion of farm family income due to nonfarm sources continues to grow nationally, it is important to understand how farm families in various regions or states are affected. This paper develops a better understanding of the contribution of income from nonfarm sources to the level and distribution of income among farm families in New York. In analyzing income distribution, the Gini ratio is decomposed to determine the effects of marginal changes in income by source to overall inequality. The results are compared with the simulated changes in income inequality due to changes in income by source as measured by an "adjusted" Gini ratio which accounts specifically for negative farm incomes. Differences in the policy implications from both...
