The State of Food and Agriculture 2008. Biofuels: Prospects, Risks and Opportunities

The State of Food and Agriculture 2008 explores the implications of the rapid recent growth in production of biofuels based on agricultural commodities. The boom in liquid biofuels has been largely induced by policies in developed countries, based on their expected positive contributions to climate-change mitigation, energy security and agricultural development. The growing demand for agricultural commodities for the production of biofuels is having significant repercussions on agricultural markets, and concerns are mounting over their negative impact on the food security of millions of people across the world. At the same time, the environmental impacts of biofuels are also coming under closer scrutiny. But biofuels also offer [...]

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.

Future Expansion of Soybean 2005-2014. Implications for Food Security, Sustainable Rural Development and Agricultural Policies in the Countries of Mercosur and Bolivia. Synthesis document. Policy Assistance Series 3

The purpose of this document is to provide greater insight into the possible implications of soybean expansion for food security, rural development and agricultural policies in these countries for the period 2005-2014. Based on country studies carried out for the investigation, this document summarizes the causes of soybean expansion in the last ten years and presents the main changes that have accompanied the process. It also quantifies in approximate terms, the growth of soybean and its products (meal and oil) between 2005 and 2014, explores the main implications of this expansion and offers a number of analytical conclusions.

WinDASI: A Software for Cost-Benefit Analysis of Investment Projects. EASYPol Series 020

This analytical tool illustrates how to carry out cost-benefit calculations of investment projects in WinDASI, after data are entered in the database. It explains, by means of a step-by step procedure, how to calculate flows of physical quantities of outputs, inputs and investment items; flows of current, discounted and cumulative costs, benefits, and net benefits; flows of incremental (With-Without project) current, discounted and cumulative net benefits; and project indicators such as the Net Present Value (NPV), the Internal Rate of Return (IRR), the Benefit/Cost Ratio, (BCR), the Switching Values (SVs) and Sensitivity Analysis. Instructions are provided on how to carry out [...]

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. A step-by-step procedure and numerical examples give operational content to the tool. For further information, see also: Charting Income Inequality. The Lorenz Curve.

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.
