Última Precios de garantía contra apoyos directos : análisis del bienestar del productor Colegio de Postgraduados Jiménez García, Eligio. Hasta el año 1993 el gobierno Mexicano intervino en el mercado de granos básicos estableciendo precios de garantía. En 1994 el gobierno crea el Programa de Apoyos al Campo, PROCAMPO, que aplica apoyos directos al ingreso monetario de los productores evitando la distorsión en precios inherente a otros esquemas de subsidio o apoyos a la producción. En la presente investigación se analiza el efecto de estos dos tipos de política sobre el bienestar del productor a través de la medición y la comparación del excedente del productor, definido como la cantidad de dinero que le da a ganar al productor una política económica por encima de sus costos de producción. Se presenta evidencia cuantitativa de que, aunque el cambio de política económica produjo una...

Ano: 2007 URL: http://hdl.handle.net/10521/1651 MODELING INTERNATIONAL TRADE IMPACTS OF GENETICALLY MODIFIED WHEAT INTRODUCTIONS AgEcon DeVuyst, Eric A.; Koo, Won W.; DeVuyst, Cheryl Sinn; Taylor, Richard D.. Planned introductions of genetically modified crop varieties can be troublesome to model. Estimation of demand and supply equations is not feasible due to lack of data. Further, specifying demand and supply equations requires calibration to a presumed equilibrium. Depending on the point chosen, highly questionable results may be obtained. We propose a model that uses existing supply, demand, and elasticity estimates. The approach relies on composite supply and demand functions. These composite functions are linear combinations of GM and non-GM varieties. We then employ this approach in a model of world wheat trade to analyze the impact of several plausible GM wheat adoption and consumer acceptability scenarios.

We estimated the economic benefits resulting from controlling soybean aphid infestation by using a multi-regional competitive dynamic equilibrium model. Results indicate that the reduction of soybean production resulting from a soybean aphid infestation is largely absorbed by reducing soybean exports, due to the higher price elasticity of export demand compared to domestic demand. Producer benefits resulting from controlling soybean aphids would increase by between $949 million and $1.623 billion in ten years under various scenarios. Results also suggest that it is economically more efficient to control soybean aphids when the rate of intrinsic growth is relatively lower, the supply price elasticity of soybean acreage is relatively more elastic, and...

Ano: 2008 URL: http://purl.umn.edu/45660 New Varieties and the Returns to Commodity Promotion: Washington Fuji Apples AgEcon Richards, Timothy J.; Patterson, Paul M.. The Fuji apple variety is relatively new in the U.S. As a new product, questions concern the relative impact of consumer learning by experience, by variety-specific promotion, or by generic apple promotion. A two-stage (LES/LAIDS) model incorporating both types of promotion is used to estimate the effect of generic and variety specific promotion, as well as consumer experience, on the demand for Fuji apples. Estimates show each to have a positive impact, and also show new or specialty apple varieties to be relatively price inelastic, but income elastic. Grower returns to promotion are calculated with an equilibrium displacement model of price changes and producer surplus. Changes in producer surplus provide a base-scenario benefit:cost ratio of 14.73....

Ano: 1998 URL: http://purl.umn.edu/28541 Evaluating the Farmer’s-Share-of-the-Retail-Dollar Statistic AgEcon Brester, Gary W.; Marsh, John M.; Atwood, Joseph A.. Conventional wisdom appears to support the thesis that declines in USDA’s farmer’s share-of-the-retail-dollar (FS) statistics are indicators of low returns to agricultural production. We estimate changes in cattle and hog FS statistics and their relationship with producer surplus (PS) for changes in various exogenous factors. The method accounts for correlations among structural parameter estimates while simulating multivariate distributions of joint parameter realizations. The simulations indicate that relationships between FS and PS depend on the source of exogenous shocks. The lack of informational content in FS statistics suggests these data should not be used for policy purposes.

Ano: 2009 URL: http://purl.umn.edu/54543 IMPACT ASSESSMENT ON MILK INCENTIVE POLICIES IN TURKEY: ANTALYA PROVINCE CASE AgEcon Sayin, Cengiz; Mencet, M. Nisa; Karaman, Suleyman. Agricultural policy instruments are implementing in different ways among all agricultural based activities. These instruments have been performed for livestock including dairy cattle and milk for many years in Turkey. Until the year 1950, agricultural support system was organized according to genetically improvement, animal illnesses and veterinary services. Nowadays, agricultural support composition has changed. Milk incentive premium is one of the supports given to producers to achieve high quality level for milk. The idea behind this premium was to provide well organized milk distribution channel from producers to modern enterprises. In this study, producers who receive milk incentive premium were chosen for face to face survey in Antalya province. It...

Ano: 2007 URL: http://purl.umn.edu/7793 GEORGIA COTTON ACREAGE RESPONSE TO THE BOLL WEEVIL ERADICATION PROGRAM AgEcon Tribble, Camille M.; McIntosh, Christopher S.; Wetzstein, Michael E.. An adaptive regression model is employed for estimating pre-and post-boll weevil eradication cotton-acreage response. Results indicate cotton acreage becoming more inelastic to own- and cross-price changes. As a result of this shift in acreage response and yield increases from eradication, net producer benefits on average are $88.73 per acre.

Ano: 1999 URL: http://purl.umn.edu/15151 Distributional Impacts of Country-of-Origin Labeling in the U.S. Meat Industry AgEcon Brester, Gary W.; Marsh, John M.; Atwood, Joseph A.. Concerns about the negative effects of U.S. meat and livestock imports on domestic livestock prices have increased interest in country-of origin labeling (COOL) legislation. An equilibrium displacement model is used to estimate short-run and long-run changes in equilibrium prices and quantities of meat and livestock in the beef, pork, and poultry sectors resulting from the implementation of COOL. Retail beef and pork demand would have to experience a one-time, permanent increase of 4.05% and 4.45%, respectively, so that feeder cattle and hog producers do not lose producer surplus over a 10-year period.
