Technology Adoption and Technical Efficiency: Organic and Conventional Dairy Farms in the United States
American Journal of Agricultural Economics - Tập 92 Số 1 - Trang 181-195 - 2010
Carlos D. Mayen, Joseph Valdes Balagtas, Corinne E. Alexander
AbstractWe compare productivity and technical efficiency of organic and conventional dairy farms in the United States. We address self‐selection into organic farming by using propensity score matching and explicitly test the hypothesis that organic and conventional farms employ a single, homogeneous technology. Utilizing the 2005 Agricultural Resource Management Survey on Dairy Costs and Returns R... hiện toàn bộ
Scale Economies and Inefficiency of U.S. Dairy Farms
American Journal of Agricultural Economics - Tập 91 Số 3 - Trang 777-794 - 2009
Roberto Mosheim, C. A. Knox Lovell
AbstractThis study employs data drawn from the 2000 Agricultural Resource Management Survey, a U.S. Department of Agriculture‐sponsored farmers’ survey. The article estimates returns to scale relationships across dairy farms of different sizes and across different regions, incorporating variables hypothesized to influence farm performance. Results point to significant scale economies in U.S. dairy... hiện toàn bộ
The Structure of U.S. Agricultural Technology, 1910–78
American Journal of Agricultural Economics - Tập 66 Số 4 - Trang 414-421 - 1984
John M. Antle
AbstractThis paper utilizes 1910–78 time‐series data and a single product aggregate translog profit function to measure the structure of U.S. agricultural technology. Duality relations are used to devise a multifactor measure of biased technical change. A measure of nonhomotheticity is introduced which indicates the effects scale change has had on aggregate cost shares. The empirical analysis find... hiện toàn bộ
On Testing the Structure of Risk Preferences in Agricultural Supply Analysis
American Journal of Agricultural Economics - Tập 73 Số 3 - Trang 743-748 - 1991
Rulon D. Pope, Richard E. Just
AbstractRisk preferences broadly affect many economic decisions when markets are incomplete. Common representations of risk preferences are constant absolute, relative, and partial relative risk aversion. Each of these preference classes has distinct impacts on choice. An econometric test for distinguishing the class of preferences is proposed and implemented for potato supply response in Idaho. T... hiện toàn bộ
Adverse Selection in Crop Insurance: Actuarial and Asymmetric Information Incentives
American Journal of Agricultural Economics - Tập 81 Số 4 - Trang 834-849 - 1999
Richard E. Just, Linda Calvin, John Quiggin
AbstractAdverse selection is often blamed for crop insurance indemnities exceeding premiums plus subsidies. However, nationwide empirical evidence has been lacking or based on inadequate county‐level data. This article uses nationwide farm‐level data on corn and soybeans to decompose incentives for participation in U.S. multiple peril crop insurance into a risk‐aversion incentive (the conventional... hiện toàn bộ
Risk Preferences of Agricultural Producers: Their Use in Extension and Research
American Journal of Agricultural Economics - Tập 61 Số 5 - Trang 1063-1070 - 1979
Douglas L. Young
A Nonparametric Investigation of Agricultural Production Behavior for U.S. Subregions
American Journal of Agricultural Economics - Tập 70 Số 2 - Trang 311-317 - 1988
Chris Fawson, C. Richard Shumway
AbstractThis research provides an empirical application of nonparametric techniques to determine whether agricultural production behavior in the United States and ten farm production regions over the period 1939 to 1982 has been inconsistent with the joint hypothesis of profit maximization, convex technology, and monotonic nonregressive technical change.
Profit, Supply, and Factor Demand Functions
American Journal of Agricultural Economics - Tập 54 Số 1 - Trang 11-18 - 1972
Lawrence J. Lau, Pan A. Yotopoulos
AbstractThe concept of the profit function provides an alternative approach to the analysis of production. First, a brief exposition of the theory of profit function is presented. Then the profit function and the factor demand functions are formulated within the Cobb‐Douglas framework. A statiscal test is devised for testing the hypothesis of constant returns to scale in all factors on the profit ... hiện toàn bộ
Risk Analysis with Single‐Index Portfolio Models: An Application to Farm Planning
American Journal of Agricultural Economics - Tập 68 Số 1 - Trang 152-161 - 1986
Robert A. Collins, Peter J. Barry
AbstractSharpe's 1963 single‐index portfolio model, the separation theorem, and a solution method suggested by Elton, Gruber, and Padberg are adapted in this paper to the farm diversification problem. The objectives are to develop risk measures, based on single‐index parameters and computationally simple methods for farm risk planning, that are suitable for microcomputers and modern hand‐held calc... hiện toàn bộ
Testing for Stochastic Dominance
American Journal of Agricultural Economics - Tập 70 Số 3 - Trang 693-700 - 1988
H. Dennis Tolley, Rulon D. Pope
AbstractA test for second‐degree stochastic dominance is proposed. The test is a permutation test using only the sample data. It is exemplified using data from Kramer and Pope. The test conclusions differ substantially from standard practice in which no statistical test is conducted.
