Global distortions to agricultural markets : new indicators of trade and welfare impacts, 1955 to 2007

Despite recent reforms, world agricultural markets remain highly distorted by government policies. Traditional indicators of those price distortions can be poor guides to the policies'economic effects. Recent theoretical literature provides indicators of trade and welfare-reducing effects of price and trade policies which this paper builds on to develop more-satisfactory indexes. The authors exploit a new Agricultural Distortion database to generate estimates of them for developing and high-income countries over the past half century. These better approximations of the trade and welfare effects of sector policies are generated without a formal model of global markets or even price elasticity estimates.Currencies and Exchange Rates,Economic Theory&Research,Agribusiness,Markets and Market Access,Trade Policy

Global Distortions to Agricultural Markets: New Indicators of Trade and Welfare Impacts, 1955 to 2007

Despite reforms over the past quarter-century, world agricultural markets remain highly distorted by government policies. Traditional indicators of those price distortions such as the nominal rate of assistance and consumer tax equivalent provide measures of the degree of intervention, but they can be misleading as indicators of the true effects of those policies. By drawing on recent theoretical literature that provides indicators of the trade- and welfare-reducing effects of price and trade policies, this paper develops more-satisfactory indexes for capturing distortions to agricultural incentives. It then exploits the Agricultural Distortion database recently compiled by the World Bank to generate estimates of them for both developing and high-income countries over the past half century, based on a sample of 75 countries that together account for all but one-tenth of the world’s population, GDP and agricultural production. While they are still only partial equilibrium measures, they provide a much better approximation of the true trade and welfare effects of sectoral policies without needing a formal model of global markets or even price elasticity estimates.Distorted incentives, agricultural and trade policies, trade restrictiveness index,

How Do Agricultural Policy Restrictions to Global Trade and Welfare Differ Across Commodities?

For decades the worldÂ’s agricultural markets have been highly distorted by national government policies, but very differently for different commodities such that a ranking of weighted average nominal rates of assistance across countries can be misleading as an indicator of the trade or welfare effects of policies affecting global markets. This article develops a new set of more-satisfactory indicators, drawing on the recent literature on trade restrictiveness indexes. It then estimates those two indicators for each of 28 key agricultural commodities from 1960 to 2004, based on a sample of 75 countries that together account for more than three-quarters of the worldÂ’s production of those agricultural commodities.distorted commodity markets, agricultural price and trade policies, trade restrictiveness index

Space plasma science, especially plasma experiments in space, is discussed. Computational simulations, wave generation and propagation, wave-particle interactions, charged particle acceleration, particle-particle interactions, radiation transport in dense plasmas, macroscopic plasma flow, plasma-magnetic field interactions, plasma-surface interactions, prospects for near-term plasma science experiments in space and three-dimensional plasma experiments are among the topics discussed

A Plan for Economic Evaluation of Organic Blueberry Production in Georgia

Blueberry consumption is increasing across the United States. Georgia’s production value of conventional blueberries has exceeded that of peaches to reach a farm-gate value of $75 million. Demand for organic food products is increasing with United States gross sales at$16.9 billion in 2006. Economic feasibility of organic blueberries is uncertain creating risk in transitioning from conventional to organic production. The principal objective is to utilize field data to determine the costs of various production methods, by developing several enterprise budgets for each adopted technique., Crop Production/Industries,
