Agricultural economists who serve as educators in emerging democracies have the opportunity to contribute to economic development by building human capital. A channel for educators to share lessons learned in these countries could benefit individuals preparing for assignments in foreign countries. Understanding the cultural and social differences in decision making systems is critical to successful educational program development and implementation. Individuals in the emerging democracies often need training in management and market economics to apply at institutional as well as personal levels. Similar training for recipients of economic development funds could result in more effective application of funds.

Using recent advances in the stochastic production frontier framework, this paper presents an empirical analysis of technical, allocative and economic efficiency of a sample of organic and conventional cotton farms located in Greece. The results suggest that both farm types in the sample examined are technically, allocatively and economically inefficient. Farmer’s age and education and farm size are important factors in explaining differentials in efficiency estimates. In comparative terms, organic farms exhibit lower efficiency scores vis-à-vis their conventional counterparts in terms of technical and economic efficiency; regarding allocative efficiency both farm types are almost equally inefficient. Low efficiency scores in both types of farming may be attributed

Private investment in plant breeding has been increasing while public plant breeding has stagnated or declined. Moreover, research investment among crop commodities is uneven. Using a comprehensive survey of U.S. plant breeders from 1994, we use a simultaneous equations model to examine incentives and public-private tradeoffs in plant breeding research among 84 crop commodities. Allocation of private breeders among crops is strongly influenced by market size, hybrid seed technology, and ease of breeding improvement. In general, the allocation of public breeders does not appear to “crowd out” private breeders, but some competition may occur in applied breeding. Public breeding declines as private breeding increases on a commodity. Public breeding is also affected by market size, ease of breeding improvement, and political influence.

A whole-farm simulation model is used to analyze the impacts of PST adoption on representative farms in Missouri and Indiana. Farmers who do not adopt experience lower average annual net cash farm incomes than adopters. Lower feed prices and/or an average PST/feed response decrease the incentive to adopt. Payment of a 5 percent carcass merit premium (CMP) and/or higher grain prices greatly increase the economic incentive to adopt.

Requiring that crop applications of manure be based on phosphorus content (P-standard) could increase poultry litter disposal costs, Microbial phytase reduces litter P content and could reduce litter disposal costs under a P-standard, For a representative Virginia turkey farm, phytase costs $2,500 and could increase value of litter used for fertilizer on the turkey farm by $390 and reduce supplemental P feed costs by $1,431. Based on assumed litter demand and supply, estimated litter export prices with phytase could exceed export prices without phytase by $3.81 per ton. Phytase net returns to the farm are an estimated $1,435.

This paper identities optimal combinations of nitrogen in the form of urea, fresh litter and composted litter for rice production. Traditional cost minimization techniques using data from experimental results conducted at three sites in Arkansas during 1991 have been employed. Comparisons between different scenarios indicate that the trade-off between the use of poultry litter and urea nitrogen depends on such factors as soil fertility, the yield response to litter application and the relative prices of nitrogen and litter. The use of litter is more economical at high target yields than at low target yields.

Recently many state and federal agencies in the U.S. have embraced an ecosystems management approach to environmental protection and regulation. This approach requires a high degree of cooperation between natural and social scientists to translate policy objectives into research hypotheses, models, and evaluation procedures to guide implementation decisions. An adaptive procedure to guide interdisciplinary research is described and illustrated with highlights of recent progress and pitfalls from the restoration initiative for the Everglades/South Florida ecosystem.
Effect of Liberalized U.S.-Mexico Dry Onion Trade: A Spatial and Intertemporal Equilibrium Analysis [статья]
Опубликовано на портале: 22-02-2005Stephen Fuller, Melanie Gillis, Houshmand A. Ziari Journal of Agricultural and Applied Economics. 1996. Vol. 28. No. 1. P. 135-147.
A spatial, intertemporal equilibrium model of the North American dry onion economy is constructed to analyze the impact of liberalized U.S.-Mexico trade. In a free-trade environment, exports of Mexican onions to the U.S. are projected to increase about 509Z0,while Mexico’s share of the U.S. market increases from 8.7 to 12.8%. Farm-level prices in the U.S. are projected to decline 8% while production declines 2.4%. The effect of free trade on U.S. producers is disproportional across regions. Northwest storage onion producers experience the greatest decline in production; however, analysis suggests that improved storage methods may offset a portion of the unfavorable impacts of liberalized trade on these producers. In spite of the unfavorable impact of free trade on U.S. dry onion producers, the industry would not be economically devastated.
Effect of Proposed Grain Standards on Marketing Costs of the U.S. Sorghum Sector: An Interregional Transshipment-Plant Location Model [статья]

Recent legislative initiatives call for studies to evaluate costs associated with cleaning U.S. grains to meet more stringent standards. This paper reports on a study which developed a mixed-integer programming model of the U.S. sorghum sector to (I) determine the least-cost geographic location for new cleaning investment at the country, terminal and port elevator stages of the marketing system and (2) measure additional system marketing costs associated with implementing the proposed standards. Results show the least-cost cleaning location to be at country and terminal elevators in excess supply regions, implementing the proposed standard would increase system costs about 2 percent.

This paper determines the effects of cattle feeders’ risk aversion on feeder cattle prices using pen data of Kansas feedlots. Higher profit risk results in lower feeder cattle prices. The elasticity of feeder cattle price with respect to profit risk was small (-0.013). The risk elasticity estimated here is similar to risk elasticities in previous studies and thus, the use of pen-level data does not seem to add much to the study of risk.
Effects of Reservoir Aquatic Plant Management on Recreational Expenditures and Regional Economic Activity [статья]

Exotic aquatic plant management is a major concern for public reservoir management in many regions of the United States. A study was conducted to measure the effects of alternative aquatic plant management strategies on recreational expenditures and regional economic activity. The study area was Lake Guntersville, Alabama, and the local economy surrounding the lake. Lake Guntersville is one of the largest reservoirs in the Tennessee Valley Authority system. Results suggested that relatively moderate levels of aquatic plant control are associated with the highest levels of recreation-related economic effects on the economy surrounding Lake Guntersville.

Employment history affects subsequent choices. Based on their original job choice, operators are divided into farmers and workers. Equations are estimated to determine their probabilities of working off-the-farm. Education increases the probability that workers work off the- farm, whereas vocational training increases farmers’ probability. The probability of working off-the-farm decreases as unearned income increases, and its impact on workers is larger than on farmers. An employed spouse increases the probability that farmers work off-the-farm, but has the opposite impact for workers. Employment density increases the probability that workers will work off-the-farm.
Employment in Agribusiness and Purchases of Agricultural Products: The Effects of Monetization in Yugoslavia [статья]
Опубликовано на портале: 17-02-2005Dragan Miljkovic, Roberto J. Garcia Journal of Agricultural and Applied Economics. 1996. Vol. 28. No. 2. P. 357-368.
Efforts to stabilize employment and output in the agricultural sector of Yugoslavia through monetization contributed to inflationary pressures. Granger causality tests suggest that increases in the rate of growth in the supply of money to subsidize state-owned agribusinesses were insufficient to maintain purchases of wheat and corn, but did cause purchases of cattle and swine. This result may be explained by producers having more flexibility in grain marketing (i.e., storage options and private buyers) and the perishability issues related to livestock marketing. The policy to maintain employment through monetization is shown to have been ineffective.
Energy Supplementation Strategies for Wheat Pasture Stocker Cattle Under Uncertain Forage Availability [статья]

Energy supplementation provides a means of reducing production risk of growing stocker cattle on winter wheat pasture. This study addresses the issue of risk aversion and energy supplement input use. Differences in supplementation practices induced by risk aversion and the effects of cattle and feed market conditions are examined. Results show that supplementation practices are likely to be similar across producers, irrespective of their risk attitudes. Cattle and feed market conditions, however, markedly affect supplementation practices. These tindings provide information for assisting stockmen in identifying efficient supplementation strategies.
