MIRAGE, Updated Version of the Model for Trade Policy Analysis: Focus on Agriculture and Dynamics AgEcon
Decreux, Yvan; Valin, Hugo.
MIRAGE is a multi-region, multi-sector computable general equilibrium model, devoted to trade policy analysis. It incorporates imperfect competition, horizontal and vertical product differentiation, and foreign direct investment, in a sequential dynamic set-up where installed capital is assumed to be immobile. Adjustment inertia is linked to capital stock reallocation. MIRAGE draws upon a very detailed measure of trade barriers and of their evolution under given hypotheses, thanks to the MAcMap database. The most recent version, presented in this paper, offers improvements in the modelling of agriculture policy and dynamics.
Tipo: Working or Discussion Paper Palavras-chave: Computable general equilibrium model; Trade policy; Dynamics; Foreign direct investment; Imperfect competition; International Relations/Trade; D58; F12; F13.

The Long-Run Impact of Energy Prices on World Agricultural Markets: The Role of Macro-Economic Linkages AgEcon
Chantret, Francois; Gohin, Alexandre.
The world prices of food and energy products have followed similar large swings in recent years. We investigate the long run relationship between these prices using a world Computable General Equilibrium model with detailed representations of food and energy markets. Particular attention is paid to specify macro-economic linkages which have often been overlooked in recent analysis and debate. We find that the omission of these macro-economic linkages has a substantial bearing on this relationship. A positive relationship due to the cost push effect has been identified in most analysis, but we find that the introduction of the real income effect may indeed imply a negative relationship between world food and energy prices. Accordingly, it is crucial to...

TRACING THE IMPACTS OF FOOD ASSISTANCE PROGRAMS ON AGRICULTURE AND CONSUMERS: A COMPUTABLE GENERAL EQUILIBRIUM MODEL AgEcon
Hanson, Kenneth; Golan, Elise H.; Vogel, Stephen J.; Olmsted, Jennifer.
Changes in food assistance policy can have impacts on economic activity and household income across the economy. Using a Computable General Equilibrium model focusing on food assistance, we found that both a hypothetical cut in food stamp benefits and a hypothetical cash-out of the Food Stamp Program led to reductions in food demand and farm production. In addition, this hypothetical cut in food stamp benefits resulted in a decline in transfer income for low-income households that was not compensated for by increased labor income. The cash-out triggered general equilibrium effects that led to higher taxes and reductions in labor income, chiefly for high-income households. The Food Assistance Computable General Equilibrium model includes modeling...

An Economy-wide Analysis of Impacts on Taiwan of Reducing Tariff Escalation on Agriculture-Related Products in WTO Doha Round Negotiations AgEcon
Lee, Huey-Lin; Chang, Ching-Cheng; Weng, Yung-Ho; Hsu, Sheng-Ming; Hsu, Shih-Hsun.
Tariff escalation becomes one of the major issues in the new Doha Round negotiation because it is viewed as a stumbling block to the industrialization development for the developing countries. When tariffs on products escalate with the stage of processing, the effective rate of protection, or the tariff expressed as fractions of value-added after deducting intermediate inputs from product value, also increases. Thus, tariff escalation potentially signals high rates of protection for value-added or processed products, and can inhibit international trade in these goods. The major purpose of this study is to examine the degrees of tariff escalations in Taiwan's agriculture -related commodities and the economic consequences to reduce them. A simplified...
