Instrumentos de política para mejorar la competitividad de la producción nacional de frijol : un análisis por tipo de variedad Colegio de Postgraduados
Borja Bravo, Mercedes.
Se espera que la liberación comercial del mercado de frijol (Phaseolus vulgaris L.) aumente las importaciones de las variedades negras, claras y pintas. Para determinar las políticas que podrían ayudar a revertir la tendencia creciente de las importaciones se validó un modelo de equilibrio espacial e intertemporal para cada tipo de frijol. Los resultados indican que la liberación comercial ubicará las importaciones en 53.1, 37.6 y 18.9 mil toneladas para frijoles negros, claros y pintos. Una reducción de 30% en los costos de distribución tendría efectos moderados, disminuyendo las importaciones de frijol en 12.6 mil toneladas, en tanto una disminución de 20% en el costo de producción y un aumento de 10% en los rendimientos reduciría las compras externas en...

WORLD FEED BARLEY TRADE UNDER ALTERNATIVE TRADE POLICY SCENARIOS AgEcon
Mao, Weining; Koo, Won W.; Krause, Mark A..
A spatial equilibrium model based on a quadratic programming algorithm was developed to analyze world feed barley trade and international competition among major exporters (Australia, Canada, the European Union, and the United States) under the current and alternative trade policy scenarios. The U.S. Export Enhancement Program (EEP) plays an important role to maintain U.S. market share in importing countries. Eliminating Canadian rail subsidy decreases Canadian offshore exports, but greatly increases its exports to the United States. The North American Free Trade Agreement (NAFTA) increases feed barley trade within North America, but has little impact on world trade flows for feed barley. Canada benefits most under the Uruguay Round Agreement of GATT...

EFFECTS OF TRADE BARRIERS ON U.S. APPLE EXPORTS AgEcon
Sreedharan, Prasanna; Devadoss, Stephen; Stodick, Leroy; Wahl, Thomas I..
We build a spatial equilibrium trade model for apples using demand and supply relations for each importing and exporting country. The model maximizes welfare subject to demand and production constraints. A trade barrier (free trade) scenario which incorporates (removes) import quotas and tariffs is run. Comparison of the solutions of the two scenarios quantifies the impacts of trade barriers on US apple exports.

Effect of a Differentially Applied Environmental Regulation on Agricultural Trade Patterns and Production Location: The Case of Methyl Bromide AgEcon
Lynch, Lori; Malcolm, Scott A.; Zilberman, David.
It has been hypothesized that differentially applied environmental regulations create pollution havens, as firms will choose to invest in countries with lax environmental standards. Using a theoretical model of pest control adoption and an empirical spatial equilibrium model, we examine one such environmental regulation, a U.S. ban on methyl bromide, to determine if an agricultural pollution haven will be created in Mexico. Alterations in agricultural production location, trade patterns, and methyl bromide use are determined. We find that, under the assumptions held, Mexico will not dramatically increase its use of methyl bromide following the ban. Sensitivity analysis to this result is conducted.

POTENTIAL IMPACTS OF GM WHEAT ON UNITED STATES AND NORTHERN PLAINS WHEAT TRADE AgEcon
Taylor, Richard D.; DeVuyst, Eric A.; Koo, Won W..
The potential introduction of genetically modified (GM) wheat has both supporters and opponents waging battle in the popular press and scholarly research. Supporters highlight the benefits to producers, while the opponents highlight the unknown safety factors for consumers. The topic is very important to the United States, as a large portion of the wheat production is exported overseas. Consumer groups in some countries are resisting GM wheat. This study utilizes a spatial equilibrium model to evaluate the trade impacts associated with GM wheat introduction along with several assumed post-GM adoption scenarios. Wheat is converted into protein equivalents to allow for substitution between wheat classes. The importance of the U.S....

Tariffs and steel: US safeguard actions AgEcon
Greenville, Jared W.; MacAulay, T. Gordon.
A multiproduct spatial equilibrium model of world steel trade is presented in this paper. The model is used to analyse the impacts of the safeguard trade barriers brought about by the USA in order to protect their domestic industry from the so-called unfair competition. Emphasis is placed on the likely effect on the Australian industry and possible policy responses available to the industry. A case study is made of Australia’s three largest export products; namely, slab, hot-rolled and cold-rolled steel, which share some substitutability in supply and demand because of the nature of the industry. As a result of the safeguard barriers to steel trade, world steel prices fell and trade shifted away from the USA to other importing regions.

Micro-simulation as a tool to assess policy concerning non-point source pollution: the case of ammonia in Dutch agriculture AgEcon
Kruseman, Gideon; Blokland, Pieter-Willem; Bouma, Foppe; Luesink, Harry H.; Mokveld, Lennard J.; Vrolijk, Hans C.J..
Non-point source pollution is notoriously difficult to assess. A relevant example is ammonia emissions in the Netherlands. Since the mid 1980s the Dutch government has sought to reduce emissions through a wide variety of measures, the effect of which in turn is monitored using modeling techniques. This paper presents the current generation of mineral emission models from agriculture based on micro-simulation of farms in combination with a spatial equilibrium model for the dispersion of manure from excess regions with high livestock intensities within the country to areas with low livestock intensities. The micro-simulation approach retains the richness in the heterogeneity of farm household decision making that are the core cause of the difficulty of...

Impacts of Greenhouse Gas Emission Regulations on the U.S. Sugar Industry AgEcon
Taylor, Richard D.; Koo, Won W..
The objective of this study is to evaluate the changes in U.S. sugar production and Greenhouse Gas (GHG) emissions from the sugar industry if the United States regulates GHG emissions from domestic sugar processing facilities. A spatial equilibrium model is developed to optimize sugar production in the United States under a base scenario and three different levels of CO2e taxes or prices of carbon offsets. This research focuses on U.S. sugar production, both beet and cane sugar. In the model the United States is divided into 6 beet growing regions and 4 cane growing regions. The model also includes Mexico as a domestic sugar growing region as Mexico has the ability to export unlimited amount of sugar into the United States under NAFTA. A rest of the...

Forest Product Trade Impacts of an Invasive Species: Modeling Structure and Intervention Trade-Offs AgEcon
Prestemon, Jeffrey P.; Zhu, Shushuai; Turner, James A.; Buongiorno, Joseph; Li, Ruhong.
Asian gypsy and nun moth introductions into the United States, possibly arriving on imported Siberian coniferous logs, threaten domestic forests and product markets and could have global market consequences. We simulate, using the Global Forest Products Model (a spatial equilibrium model of the world forest sector), the consequences under current policies of a wide-spread, successful pest invasion, and of plausible trading partner responses to the successful invasion. We find that trade liberalization would have a negligible effect on U.S. imports of Siberian logs and, consequently, on the risk of a pest invasion. But, if it happened, possibly through trade in other commodities, a successful and widespread pest invasion would have large effects on...

Tariffs and Steel: The US Safeguard Actions AgEcon
Greenville, Jared W.; MacAulay, T. Gordon.
This paper presents a multi-product price linked spatial equilibrium model of world steel trade. The model is used to analyse the impacts of the safeguard trade barriers brought about by the United States in order to protect their domestic industry from so called unfair competition. Emphasis is placed on the likely effect to the Australian industry and possible policy responses available to the industry. A case study is made on Australia's three largest export products, namely slab, hot-rolled and cold-rolled steel, which share some substitutability in supply and demand due to the nature of the industry.

Modelling Water Use in Thailand AgEcon
Piyanuch, Wuttisorn; MacAulay, T. Gordon; Batterham, Robert L..
In this paper a model is proposed for analysing alternative policies that might be used in allocating water in Thailand. The model used is an integration of farm linear programming models with a spatial equilibrium model, using the so-called price-linked farm and spatial model (Batterham and MacAulay, 1994). A method of linking spatial equilibrium models and linear programming representations of farm models via the demand side as opposed to the supply side is outlined in this paper. A case study is made of the Chao Phraya Delta, an area that is progressively challenged by competing claims for water use and which needs to better allocate water resources.
