Food and Agricultural Policy Trends After the 2008 Food Security Crisis Renewed Attention to Agricultural Development. EASYPol Series 125

Published under the The Food and Agriculture Policy Decision Analysis (FAPDA) project, this paper reviews the policy decisions taken from October 2008 to mid 2010. It aims to analyze the policy trends during the period that followed the peak of the 2008 Food Security Crisis. It seeks to identify possible changes in the policy orientation adopted by selected FAO member countries. This paper aspires to answer to the question raised as the result of the 2009 FAO publication on "Country Responses to the Food Security Crisis" which had found quite deep changes in the orientation of policies put in place by [...]

International Price Shocks and Technological Changes for Poverty Reduction in Burkina Faso. A General Equilibrium Approach. EASYPol Series 071

After sketching the mutual links between economic growth, agriculture, technology, poverty reduction and external factors, this paper analyses the implications of recent international price shocks on welfare and growth, notably energy and agricultural products, for Burkina Faso, a less industrialised, low-income, food-deficit, net oil-importing country. The socio-economic impacts of the above-mentioned external shocks are analysed by means of a Computable General Equilibrium model (CGE). The paper also discusses the extent to which technological changes in agriculture, specifically the introduction of “Good Agricultural Practices” (GAP) towards “conservation agriculture”, could mitigate the welfare and growth losses derived by international price shocks.  Additionally, it is shown [...]

Social Welfare Analysis of Income Distributions: Social Welfare, Social Welfare Functions and Inequality Aversion. EASYPol Series 041

This analytical tool illustrates the concept of social welfare and the possible ways to define social welfare functions. In particular, it deals with how to pass from inequality to social welfare analysis and how social welfare analysis may embody different attitudes with regard to inequality aversion. A step-by-step procedure and numerical examples are also discussed to give operational content to the tool. For more information, see also: Charting Income Inequality. The Lorenz Curve.

The State of Food and Agriculture. Paying Farmers for Environmental Services

The State of Food and Agriculture 2007 explores the potential for agriculture to provide enhanced levels of environmental services alongside the production of food and fibre. The report concludes that demand for environmental services from agriculture – including climate change mitigation, improved watershed management and biodiversity preservation – will increase in the future, but better incentives to farmers are needed if agriculture is to meet this demand. As one among several other possible policy tools, payments to farmers for environmental services hold promise as a flexible approach to enhancing farmer incentives to sustain and improve the ecosystems on which we [...]

Policy Impacts on Inequality: Simple Inequality Measures. EASYPol Series 080

This module illustrates the simplest ways to measure inequality drawing on the statistical concepts of location, shape and variability. In particular, the following measures will be addressed: a) the range; b) the relative mean deviation; c) the variance; d) the coefficient of variation; and e) the standard deviation of logharitms. For all these measures, step-by-step procedures and numerical examples are also discussed. For more information, see also: Charting Income Inequality. The Lorenz Curve.

Policy Impacts on Inequality: Inequality and Axioms for its Measurement. EASYPol Series 054

This tool illustrates the concept of desirable properties any inequality index should respect. In particular, it introduces the distinction between a positive and a normative approach to inequality analysis. Then, it discusses the role of axioms in inequality measurement and their conceptual meaning. Finally, using the Gini Index and the variance, a step-by-step procedure and numerical examples are introduced for operational purposes. For further information, see also: Charting Income Inequality.

Policy Impacts on Inequality. Decomposition of Income Inequality by Income Sources. EASYPol Series 053

This analytical tool illustrates how to decompose inequality measures by income sources. In particular, it discusses this decomposition in the context of the Gini and the Theil Indexes.

Policy impacts on inequality: Decomposition of Income Inequality by Subgroups. EASYPol Series 052

This analytical tool illustrates how to decompose inequality measures by subgroups of populations. In particular, it defines the concepts of within and between inequality and analyses how different inequality indexes perform with respect to this decomposition. In particular, the performance of the analysis of variance, the Gini Index and the Theil Index will be discussed. A step-by-step procedure and numerical examples give operational content to the tool.

Describing Income Inequality. Theil Index and Entropy Class Indexes. EASYPol Series 051

This analytical tool illustrates the entropy class of inequality indexes. In particular, it shows how different inequality indexes may be obtained by using a general definition (class) of indexes by assigning different values to a fixed parameter. A step-by-step procedure and numerical examples then show how to move from conceptual to operational ground. For further information, see also: Charting Income Inequality. The Lorenz Curve.

Policy Impacts on Inequality. Welfare Based Measures of Inequality: The Atkinson Index. EASYPol Series 050

This analytical tool illustrates one of the most popular welfare-based measures of inequality, the Atkinson Index . In particular, it discusses the foundations of this Index, in terms of social welfare specifications, and the concept of equally distributed equivalent income on which the measure is based. The use of this measure is then exemplified in a step-by-step procedure and in a numerical example.
