How do agricultural policy restrictions to global trade and welfare differ across commodities ? by P. J Lloyd( Computer File )
9 editions published in 2009 in English and Undetermined and held by 20 libraries worldwide
For decades the world's agricultural markets have been highly distorted by national government policies, but very differently for different commodities. Hence a weighted average across countries of nominal rates of assistance or consumer tax equivalents for a product can be misleading as an indicator of the trade or welfare effects of policies affecting that product's global market. This is especially the case when some countries tax and others subsidize its production or consumption. This article develops a new set of more-satisfactory indicators for that purpose, drawing on the recent literature on trade restrictiveness indexes. It then exploits a global agricultural distortions database recently compiled by the World Bank to generate the first set of estimates of 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 world's production of those agricultural commodities. These reveal the considerable extent of reforms in agricultural policies of developing as well as high-income countries over the past two decades
Changing Contributions of Different Agricultural Policy Instruments To Global Reductions In Trade And Welfare by Johanna L Croser( Book )
5 editions published in 2010 in English and held by 19 libraries worldwide
Trade negotiators and policy advisors are keen to know the relative contribution of different farm policy instruments to international trade and economic welfare. Nominal rates of assistance or producer support estimates are incomplete indicators, especially when (especially in developing countries) some commodities are taxed and others are subsidized in which case positive contributions can offset negative contributions. This paper develops and estimates a new set of more-satisfactory indicators to examine the relative contribution of different farm policy instruments to reductions in agricultural trade and welfare, drawing on recent literature on trade restrictiveness indexes and a recently compiled database on distortions to agricultural prices for 75 developing and high-income countries over the period 1960 to 2004
Global distortions to agricultural markets new indicators of trade and welfare impacts, 1955 to 2007 by P. J Lloyd( file )
4 editions published in 2009 in English and held by 16 libraries worldwide
"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. "--World Bank web site
Agricultural Distortions In Sub-Saharan Africa : Trade And Welfare Indicators, 1961 To 2004 by Johanna L Croser( Book )
4 editions published in 2010 in English and held by 14 libraries worldwide
For decades, agricultural price and trade policies in Sub-Saharan Africa have hampered farmers' contributions to economic growth and poverty reduction. Although there has been much policy reform over the past two decades, the injections of agricultural development funding, together with ongoing regional and global trade negotiations, have brought distortionary policies under the spotlight once again. A key question asked of those policies is: How much are they still reducing national economic welfare and trade? Economy-wide models are able to address that question, but they are not available for many poor countries. Even where they are, typically they apply to just one particular previous year and so are unable to provide trends in effects over time. This paper provides a partial-equilibrium alternative to economy-wide modeling, by drawing on a modification of so-called trade restrictiveness indexes to provide theoretically precise indicators of the trade and welfare effects of agricultural policy distortions to producer and consumer prices over the past half-century. The authors generate time series of country level indexes, as well as Africa-wide aggregates. They also provide annual commodity market indexes for the region, and a sense of the relative importance of the key policy instruments used
Novel indicators of the trade and welfare effects of agricultural distortions in OECD countries by Kym Anderson( Book )
5 editions published in 2010 in English and held by 13 libraries worldwide
Agricultural markets in OECD countries have long been highly distorted by government policies. Traditional weighted average aggregates of the price distortions involved, such as producer and consumer support estimates (PSEs and CSEs), can be poor indicators of the trade restrictiveness and economic welfare losses associated with them, especially if a country's support estimates vary a lot across the product range. Certainly estimates of trade and welfare effects of price supports can be obtained from sectoral or economywide models using price elasticity estimates, but the results can be contentious if there is no consensus on what model specification and elasticity parameters to use. This paper shows that, if there is a willingness to accept simple assumptions about elasticities, it is possible to generate indicators of the welfare and trade restrictiveness of agricultural policies using no more than the price and quantity data needed to generate PSEs and CSEs. These new indexes thus provide an attractive supplement to the current policy monitoring regime developed by the OECD Secretariat

New indicators of how much agricultural policies restrict global trade by Kym Anderson( file )
2 editions published in 2010 in English and held by 5 libraries worldwide
"Despite recent reforms, world agricultural markets remain highly distorted by government policies. Traditional indicators of agricultural and food price distortions such as producer and consumer support estimates (PSEs and CSEs) can be poor guides to the policies' trade effects. Two recent studies provide much better indicators of trade- (and welfare-)reducing effects of farm price and trade policies, but they provide somewhat differing numbers. This paper explains why those estimates differ and how they might be improved for use in on-going annual monitoring of the trade restrictiveness of agricultural policies in both high-incmoe and developing countries."

How do agricultural policy (1) restrictions to global trade and welfare differ across commodities? by Johanna L Croser( file )

For decades the world'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 world's production of those agricultural commodities
Novel (1) indicators of the trade and welfare effects of agricultural distortions in OECD countries by Kym Anderson( file )
1 edition published in 2010 in English and held by 4 libraries worldwide
Agricultural markets in OECD countries have long been highly distorted by government policies. Traditional weighted average aggregates of the price distortions they involve, such as producer and consumer support estimates (PSEs and CSEs), can be poor indicators of the trade restrictiveness and economic welfare losses associated with them, especially if a country's support estimates vary a lot across the product range. Supplementing those measures with estimates of trade and welfare effects of price supports requires the use of a sectoral or economy wide model and price elasticity data. This paper shows that, in the absence of such a model, and a willingness to make simple assumptions about elasticities, it is possible to generate more satisfactory indicators than PSEs and CSEs using no more than the price and quantity data used to generate them. These new indexes provide an attractive supplement to the current policy monitoring regime developed by the OECD Secretariat

Despite recent reforms, world agricultural markets remain highly distorted by government policies. Traditional indicators of those price distortions such as producer and consumer support estimates (PSEs and CSEs) can be poor guides to the policies' economic effects. Recent theoretical literature provides scalar index numbers of trade- and welfarereducing effects of price and trade policies which this paper builds on to develop moresatisfactory indexes that can be generated using no more than the data used to generate PSEs and CSEs. We then exploit a new Agricultural Distortion database to provide time series estimates of index numbers for 75 developing and high-income countries over the past half century

How much do agricultural policies restrict trade? comparing trade restrictiveness indexes by Kym Anderson( file )
1 edition published in 2010 in English and held by 2 libraries worldwide
Recently the Bank has provided new indicators for monitoring the extent to which agricultural policies restrict international trade in farm goods. They come from two studies with differing methodologies and data sources, and each provides less-than-perfect estimates. This note shows how and explains why the two indexes differ for some countries
