#### Influencing Policy Processes. Lessons from Experience. Policy Assistance Series 4

The literature available on best practices for providing policy assistance and influencing effectively national policy processes is insufficient to provide appropriate guidance to those whose work it is to help countries in shaping their policies and ensure that the advice they provide has a good chance of being adopted by governments.
Based on these premises, this study, qualitative in nature, uses the results of a review of existing literature, a consultation with 25 agencies conducting policy assistance activities and an in-depth review of 12 FAO policy assistance projects to highlight a series of good practices that can contribute to enhancing the [...]

#### 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.

#### Global Plan of Action for Animal Genetic Resources and the Interlaken Declaration

Sustainable use, development and conservation of the world’s livestock genetic resources are of vital importance to agriculture, food production, rural development and the environment. In recognition of the need to develop an effective framework for the management of these resources and to address the threat of genetic erosion, 109 countries came together in September 2007 at the first International Technical Conference on Animal Genetic Resources for Food and Agriculture held in Interlaken, Switzerland. The Conference adopted the Global Plan of Action for Animal Genetic Resources – which includes 23 strategic priorities for action to promote the wise management of these [...]

#### 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.

#### 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.

#### 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.

#### 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.

#### 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.

#### Inequality Analysis: The Gini Index. EASYPol Series 040

This analytical tool addresses the most popular inequality index, the Gini index. It discusses its characteristics and the link with another popular graphical tool of representing inequality, the Lorenz Curve. Extended version of the Gini Index with different weighting schemes are also discussed. The use of the Gini Index and of its generalised versions is explained through a step-by-step procedure and numerical examples.
