Implicaciones de NAFTA, TLCUEM y de la integración de China a la OMC en el mercado de la berenjena: una perspectiva de equilibrio espacial AgEcon
Guajardo, Ramon; Rios, Maricela.
Este artículo estudia el impacto de NAFTA, TLCUEM y de la integración de China a la OMC en el mercado mundial de la berenjena. Los impactos son medidos en términos de cambios en los flujos comerciales y en los precios. Se especificó y estimó un modelo de equilibrio espacial con precios endógenos y se simularon escenarios alternativos: con y sin la operación de los tratados y la integración de China a la OMC. Los resultados mostraron que la operación de estos tratados crea desviación de comercio. Además, la integración de China a la OMC aun con libre comercio mundial no impacta al mercado mundial de la berenjena.

Effects of the Conservation Reserve Program on Elevator Merchandising Margins in Oklahoma AgEcon
Adam, Brian D.; Hong, Seung Jee; Dicks, Michael R..
The Conservation Reserve Program (CRP) takes cropland out of production for 10 years, reducing grain supplies available to elevators. Results suggest that the program has negatively impacted elevator merchandising margins, but that elevators adjusted rather quickly to CRP changes, making most of the adjustment within 1 year. The reduction in margins reflects an element of pressure on agribusiness that has not been measured in previous studies.

Expectations, Experiences, Trust in the Case of Short Circuit Food Supply Networks AgEcon
Martino, Gaetano; Fritz, Melanie.
Farmers Markets are receiving an increasing attention by both food chains actors and social scientists. Economic and sociological studies are contributing to the comprehension of these forms of exchange. Both consumers and producers are fostering their expectations about the renewal of a mode of exchange which sustained local production‐ consumptions linkages. The main economic function of these organizational structures seems to be the reduction of the price paid by the consumers and the enhancements of allocation of farm products. The basic interpretation of these forms of exchange focuses on market structure, nonetheless the exchange relationships seems to emphasize several dimensions, including economic and cultural aspects. The objective of the paper...

Can German Wine Cooperatives Compete on Quality? AgEcon
Schamel, Guenter.
The German Agricultural Society (DLG) manages a multi-round annual quality control scheme where wines undergo a blind, sensory testing procedure using a 5-point scale to determine superior quality wines worthy of an annual award (Bronze, Silver, Gold, and Gold Extra). We develop a hedonic model for the 2005 award competition estimating implicit prices for different product attributes including sensory awards, quality categories, and wine style. We also control for regional origin, variety, color, and age. To discern the impact of ownership structure, we distinguish cooperatives and private wineries. Silver and Bronze awards show significant price effects relative to Gold. We also estimate highly significant price effects between quality categories (e.g....

Implementing Electricity Restructuring: Policies, Potholes, and Prospects AgEcon
Brennan, Timothy J.; Palmer, Karen L.; Martinez, Salvador A..
Electricity is one of the last U.S. industries in which competition is replacing regulation. We briefly review the technology for producing and delivering power, the history of electricity policy, and recent state and international experience. We then outline the major questions facing policymakers as they decide whether, when, and how to implement restructuring. We conclude with some thoughts on the California electricity crisis and other political controversies. Although the California experience has come to define what it means for electricity markets to fail, most of the problems it raised are among those we know how to solve or prevent. The still unresolved make-or-break issue remains whether the cooperation necessary to maintain reliability is...

GALE-SHAPLEY MATCHING IN AN EVOLUTIONARY TRADE NETWORK GAME AgEcon
Tesfatsion, Leigh.
For a postscript copy of this paper, click <a href="/Data/isu/er43.ps"> here. </A> This study investigates the performance of Gale-Shapley matching in an evolutionary market context. Computational experimental findings are reported for an evolutionary match-and-play trade network game in which resource-constrained traders repeatedly choose and refuse trade partners in accordance with Gale-Shapley matching, participate in risky trades modelled as two-person prisoner's dilemma games, and evolve their trade behavior over time. Particular attention is focused on correlations between ex ante market structure and the formation of trade networks, and between trade network formation and the types of trade behavior and social welfare outcomes that...

Pourquoi et comment l’instabilité est-elle une caractéristique structurelle des marchés agricoles? AgEcon
Boussard, Jean-Marc.
Agricultural price volatility is "bad". But where does it come from? Remedies are completely different for "endogenous" or "exogenous" fluctuations. The recent crisis seems to indicate that exogenous remedies have been applied to endogenous fluctuations.

DEVELOPMENT OF A MARKET BENCHMARK PRICE FOR AGMAS PERFORMANCE EVALUATIONS AgEcon
Good, Darrel L.; Irwin, Scott H.; Jackson, Thomas E..
The purpose of this research report is to identify the appropriate market benchmark price to use to evaluate the pricing performance of market advisory services that are included in the annual AgMAS pricing performance evaluations. Five desirable properties of market benchmark prices are identified. Three potential specifications of the market benchmark price are considered: the average price received by Illinois farmers, the harvest cash price, and the average cash price over a two-year crop marketing window. The average cash price meets all of the desired properties, except that it would not be easily implementable by producers. It can be shown, though, that the price realized via a more manageable strategy of "spreading" sales during the marketing...

Trader Behaviour and Performance in Live Animal Marketing in Rural Ethiopian Markets AgEcon
Jabbar, Mohammad A.; Benin, Samuel; Gabre-Madhin, Eleni Z.; Paulos, Zelekawork.
In this paper, performance of a sample of 131 livestock traders in 38 rural Ethiopian highland markets was analysed in terms of their costs and margins, how these were influenced by their assets and trading practices, and the implications of the findings for policy were outlined. The paper is divided into three main sections: description of the profiles of traders, their assets, trading behaviour and practices; estimates of costs and margins for a set of recent transactions; and econometric analysis of the factors explaining differences in performance with a particular focus on transaction costs. Most traders used own capital as access to credit, especially formal credit, was limited. The livestock market was characterised by non-standardised products and...

Which Broiler Part is the Best Part? AgEcon
Goodwin, Harold L., Jr.; McKenzie, Andrew M.; Djunaidi, Harjanto.
Predominance of production and marketing contracts in the broiler industry suggests a traditional analysis of price relationships might no longer be appropriate. In this study, markets for broiler cuts are defined as spatial. Results of a vector autoregressive regression analysis of monthly USDA data from 1987 to 2000 verify the price relationship between white meat and whole broiler prices. Price shocks in the boneless skinless breast market have a greater effect than dark meat shocks, suggesting this market is most important in price transmission. These results will assist industry participants to form more effective marketing and pricing strategies, thus adding efficiency to the market.

TECHNOLOGICAL CHANGE IN THE U.S. BEEF AND PORK SECTORS: IMPACTS ON FARM-WHOLESALE MARKETING MARGINS AND LIVESTOCK PRICES AgEcon
Marsh, John M.; Brester, Gary W..
Real livestock prices and farm-wholesale marketing margins have steadily declined over the past 20 years. Many studies have examined the effects of increasing packer concentration on these declines. However, most have generally failed to account directly for technological change in livestock production and red meat slaughtering. We estimate reduced form models for beef and pork farm-wholesale marketing margins and cattle and hog prices that specifically include measures of technological change. Empirical results indicate that meat packing technology has reduced real margins and technological change embodied in cattle and hog production accounts for substantial declines in real slaughter cattle and hog prices. When technological change is explicitly...

Tart Cherry Yield and Economic Response to Alternative Planting Densities AgEcon
Me-Nsope, Nathalie Mongue.
The study investigates the economic response of tart cherry yields to planting density using an unbalanced longitudinal yield data from tart cherry orchards in Northwest Michigan. The relationship between tart cherry yield and tree age is specified as a linear spline function and planting density interacts with tree age. A random effect method, treating block as random, is used to estimate the spline function. Stochastic simulation was used to estimate the mean and variance of the product of two random variables (price and yield), and the coefficient of variation was used as a measure of how much risk is involved in corn/soybeans production relative to tart cherries production. Estimates of the variance provided the discount factor (10%) and with yields...

A Hedonic Analysis of Cattle Prices in the Central Corridor of West Africa: Implications for Production and Marketing Decisions AgEcon
Williams, Timothy O.; Okike, Iheanacho; Spycher, Ben.
Detailed weekly sales transactions data for the period January 2000-June 2001 from three frontier markets in the central corridor of West Africa were analyzed to identify the factors influencing short-run, intra-year cattle prices. The empirical results indicate that in addition to market location and seasonality of supply and sales, market participants show systemic preferences for specific cattle attributes (sex, weight, condition and finish) and are willing to pay premium prices consistent with their preferences. Communicating this information to producers can assist them to tailor their production and marketing decisions to meet market expectations and thereby improve their competitiveness, profitability and intra-regional livestock trade. Innovative...

Tobit regression to estimate impact of EU market intervention in dairy sector AgEcon
Wocken, Meike; Kneib, Thomas.
This study examines the effect of European intervention politics in the European butter market in the context of market liberalization using the example of Germany. A heteroscedastic Tobit model is estimated using German butter market data from 1973-2010. There is evidence that price support has reduced price instability in the butter market. Simulation indicates that enhancing intervention price causes an increase in the expected butter price in the long-run, even though if market price is higher than intervention level. We find changing effects of stockpiling. If difference between market and intervention price is small and stock quantity is high, it significantly contributes to reducing price volatility. On the contrary if price difference is large and...

1997 PRICING PERFORMANCE OF MARKET ADVISORY SERVICES FOR CORN AND SOYBEANS AgEcon
Jackson, Thomas E.; Irwin, Scott H.; Good, Darrel L..
The purpose of this research report is to present an evaluation of advisory service pricing performance in 1997 for corn and soybeans. Specifically, the average price received by a subscriber to an advisory service is calculated for corn and soybean crops harvested in 1997. The average net advisory price across all 23 corn programs is $2.32 per bushel. The net advisory prices for corn range from a minimum of $2.00 per bushel to a maximum of $2.74 per bushel. The average net advisory price across all 21 soybean programs is $6.40 per bushel. The net advisory prices for soybeans range from a minimum of $6.08 per bushel to a maximum of $6.99 per bushel.

An Econometric Analysis of Price Dynamics in the Presence of a Price Floor: The Case of American Cheese AgEcon
Chavas, Jean-Paul; Kim, Kwansoo.
In this paper, we present an econometric analysis for the effects of a price floor on price dynamics and price volatility. A price floor (implemented as a part of government pricing policy) provides a censoring mechanism for price determination. We specify and estimate a dynamic Tobit model under time-varying volatility. The model is applied to analyze the effects of a price support program on price dynamics and price volatility in the U.S. American cheese market. The econometric analysis provides useful insights on price dynamics in the presence of a government-determined price floor.

Seasoning a Monopsonic Processor for Collective Action amongst Pepper Producers in Costa Rica AgEcon
Saenz-Segura, Fernando J.F.; Schipper, Robert A.; D'Haese, Marijke F.C..
The small-scale pepper producers in the El Roble settlement Costa Rica face a monopsonistic market. Only one processing firm is buying the fresh pepper bunches. The processor has all bargaining power to decide on the price paid to the farmers and the quality selection criteria. The rejection rates are high, which is why farmers decided to market their pepper collectively. They started organizing the selection and transport of pepper and entered into group contracts with the firm. We use a non-linear integer simulation model to predict the price level and contractual form (individual or group contracts) which maximises the income of the firm and farmers under three conditions, namely, monopsony (firm holds all bargaining power), monopoly (producers hold all...
