A Spatial Equilibrium Model of the Impact of Bio-Fuels Energy Policy on Grain Transportation Flows AgEcon
Ahmedov, Zafarbek; Power, Gabriel J.; Vedenov, Dmitry V.; Fuller, Stephen W.; McCarl, Bruce A.; Vadali, Sharada.
Traffic flows in the U.S. have been affected by the substantial increase and, as of January 2009, decrease in biofuel production and use. This paper considers a framework to study the effect on grain transportation flows of the 2005 Energy Act and subsequent legislation, which mandated higher production levels of biofuels, e.g. ethanol and biodiesels. Future research will incorporate changes due to the recent economic slowdown.

AN ANALYSIS OF THE IMPACT OF A BAN OF METHYL BROMIDE ON THE U.S. WINTER FRESH VEGETABLE MARKET AgEcon
Deepak, M.S.; Spreen, Thomas H.; VanSickle, John J..
This study evaluates the economic impact of a ban on methyl bromide on the U.S. winter fresh vegetable market for six major crops: tomatoes, green peppers, cucumbers, squash, eggplant, and watermelons. Florida is the primary domestic supplier of these products. Mexico and Texas are the competing suppliers of the five vegetable crops and peppers, respectively. Leontief technologies represent both monocrop and double-crop production systems; linear inverse demand functions represent four demand regions in the U.S. and Canada. By increasing production costs and reducing yields, a ban on methyl bromide decreases Florida's FOB revenues by 54% and increases those of Mexico by 65%. Price increases to U.S. fresh vegetable consumers range from near zero to over...

DISTINGUISHING BETWEEN EQUILIBRIUM AND INTEGRATION IN MARKETS ANALYSIS AgEcon
Li, Jau-Rong; Barrett, Christopher B..
This paper introduces a new market analysis methodology based on maximum likelihood estimation of a mixture distribution model incorporating price, transfer cost, and trade flow data. Not only does this method obviate statistical problems associated with conventional price analysis methods, it also permits differentiation between market integration and competitive market equilibrium. The model generates estimates of the frequency of alternative regimes, combinations of which provide useful, intuitive measures of intermarket tradability, competitive market equilibrium, perfect integration, segmented equilibrium, and segmented disequilibrium. An application to trade in soybean meal among Pacific Rim economies demonstrates the usefulness of the method.

Grain Distribution in Ghana under Imperfectly Competitive Market Conditions AgEcon
Langyintuo, Augustine S..
Interspatial and intertemporal grain distribution in Ghana is a private sector activity carried out mainly by traders. These traders sometimes collude to maximize their joint profits. By so doing they influence the conduct of the grains market. To examine the effect of their actions on the informal maize market in Ghana, a spatial equilibrium model was estimated under three scenarios: (1) Perfect competition, (2) Cournot-Narsh conjectures, and (3) Collusion. The results indicate that imperfect competition distorts grain flows, reduces consumer welfare and depresses traders’ sales revenue. Collusive behavior of traders, on the other hand, causes the greatest distortion of grain flows as well as trader and consumer welfare. These results draw attention to...

The Economic Impacts of Avian Influenza on World Poultry Trade and the U.S. Poultry Industry: A Spatial Equilibrium Analysis AgEcon
Djunaidi, Harjanto; Djunaidi, Andrew C.M..
Simulation results showed that simultaneous outbreaks of highly pathogenic avian influenza (HPAI) in Asia, the United States, Brazil, and selected European countries will have significant impacts on world poultry trade. Assuming demand for chicken meat is constant, the global export price is simulated to increase by 9.63%. HPAI outbreaks in the United States, Economic Union, and Brazil will have a greater impact on export price than in any other possible three-region case. Outbreaks in the United States and Brazil would still lead to major impacts on world poultry trade, confirming large country effects.

The Free Trade Area of the Americas and the Market for Processed Orange Products AgEcon
Spreen, Thomas H.; Brewster, Charlene; Brown, Mark G..
The proposed Free Trade Area of the Americas would join the world’s two largest processed orange producing regions: Brazil and the United States. Because the United States currently imposes a sizeable tariff on imported processed orange products, there is concern by U.S. orange growers over possible adverse effects resulting from tariff elimination. A model of the world processed orange market is developed as a spatial equilibrium model with implicit supply functions based on the dynamic behavior of orange production. The model is used to estimate the impact of U.S. tariff elimination on U.S. production, grower and processor prices, and imports. The results suggest a sizeable price impact on U.S. producers if the tariff is eliminated.

Two Ways of Estimating a Transport Model AgEcon
Jansson, Torbjorn.
In this article, it is shown how the parameters of a transport model can be estimated in a way that, in contrast to previously used methods, utilizes observations of regional prices as well as of trade costs. The proposed method uses bi-level programming to minimize a weighted least squares’ criterion under the restriction that the estimated parameters satisfy the Kuhn-Tucker conditions for an optimal solution of the transport model. We use Monte-Carlo simulations to trace out some properties of the estimator and compare it with a traditional calibration method. The analysis shows that the proposed technique estimates prices as well as trade costs more efficiently.

WORLD MALT AND MALTING BARLEY: COMPETITION, MARKETING, AND TRADE AgEcon
Satyanarayana, Vidyashankara; Wilson, William W.; Johnson, D. Demcey; Dooley, Frank J..
Recent trends in production marketing, trade, and policies affecting world malting barley and malt sector are examined. A spatial equilibrium model of production and trade is used to assess the effects of alternative levels of supply, demand, and policy variables on composition and direction of malting barley and malt trade flows.
