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.

Monitoring Policy Impacts (MPI). The application of the logframe method. EASYPol Series 058
The LogFrame method is an instrument employed by analysts, planners and managers for:
problem analysis,
objective formulation,
planning,
implementation,
monitoring and evaluation
of selected, objective-oriented interventions that aim at a change of reality from a situation which is perceived as negative towards a positive situation.
Because of its general logic, the LogFrame method can be applied to any type of objective oriented tasks, irrespective of the nature, level of aggregation or complexity of the problem to be solved. Though originally developed as a method for project planning and management, the method and its methodological principles can analogously be applied to analysis, planning and management of programmes and [...]

Monitoring Policy Impacts (MPI). Setting up and organizing MPI. EASYPol Series 059
Once a decision is taken to establish an MPI system, this module puts forward the aspects to be considered in organizing such a system and discusses possible institutional/organizational set ups. The following four organizational options are distinguished:
Setting up an MPI capacity
at central government level, but not directly affiliated to a line ministry;
as a special unit in a line ministry (e.g. Ministry of Agriculture);
as a separate project-type unit;
as an external institution (research institute, NGO, consulting firm).
Each of these options has special advantages and disadvantages. Which of the options is selected depends on the policy to be monitored, on the expectations from [...]

Monitoring Policy Impacts (MPI). The eight methodo-"logical" steps for MPI. EASYPol Series 057
This paper presents the eight methodo-“logical” steps for monitoring policy impacts (MPI), comprising:
Step 1: Initiation and preparation of MPI
Step 2: Policy review and analysis
Step 3: Development of the impact model
Step 4: Selection of impact indicators
Step 5: Research design
Step 6: Information and data collection
Step 7: Data compilation, processing and analysis
Step 8: Feedback of results of MPI to policy makers, clients, public.
It is pointed out that the eight steps represent a logical sequence but that the steps are closely interlinked and that there are likely possible feedback cycles to previous steps. In a concluding section, conditions for a practical application of MPI [...]

Monitoring Policy Impacts (MPI). The role of MPI in policy formulation and implementation. EASYPol Series 056
Monitoring Policy Impacts (MPI) is a policy management instrument, applied to improve the efficacy of policies in reaching their objectives. MPI identifies diversions of reality from plan when they occur, as well as the causes of such diversions, thus allowing immediate corrections, if required, and respective adjustments in policy design and implementation. With its special features – focussing on impacts at policy level, tracing of flaws, timeliness of recording and feed back - MPI is related to but distinct from other conventional monitoring and evaluation concepts, such as implementation monitoring, project and programme monitoring, and evaluations which are conducted ex-post [...]

Social Welfare Analysis of Income Distributions: Ranking Income Distributions with Generalised Lorenz Curves
This module documents calculation and use of Lorenz curves for inequality analysis. Specifically, it illustrates how Generalised Lorenz (GL) Curves can be used to identify the best income distribution on social welfare grounds within a set of alternative income distributions generated by different policy options where ordinary Lorenz curves fail to work. It is developed for capacity developent and operational purposes.

Poverty Analysis. Poverty and Dominance. EAYSPol Series 035
This analytical tool illustrates how some simple poverty measures may be linked with dominance conditions between particular types of curves. This strongly resembles the dominance conditions already set out in the case of Lorenz curves1. In particular, dominance conditions will be derived for the headcount ratio and for the Foster-Greer-Thorbecke (FGT) measures showing that, under certain conditions, the poverty line specification is not necessary. This module also introduces the concept of the Three I’s of Poverty (TIP) curve. As a way to analyse poverty, this module is based on a different approach to poverty measurement. Nor does it recourse to [...]

Equivalence Scales: Objective Methods. EASYPol Series 034
This analytical tool illustrates how to use objective methods to derive Equivalence scales. The focus will be on the Engel method, on the Rothbarth method and on the Utility-based methods. The main difference between these methods is that the first two are based on proxy variables for the household well-being, while the last set of methods is based on the consideration of the overall preferences revealed by consumers.

Equivalence Scales. Subjective Methods. EASYPol Series 033
This analytical tool illustrates how to use subjective methods to derive equivalence scales. Different methods exist, but the focus will be on parametric methods. These methods are based on the definition of two broad sets of parameters. The first defines the degree of economies of scale within any given household; the second defines how much any further member adds to the cost of running a family. As we will see, the two concepts are linked, giving rise to a variety of ways to parameterise equivalence scales.

Equivalence Scales. General Aspects. EASYPol Series 032
This analytical tool illustrates how inequality and poverty analysis may be carried out when the income distribution is defined over households (i.e. household incomes) and not over individuals (i.e. individual incomes). When household incomes are considered, a problem arises with regard to the possibility of comparing monetary incomes of different households with different numbers of inhabitants. In this case, and as described in this module, a correction should be made to meaningfully compare different situations. This correction is called an equivalence scale. An equivalence scale may be a simple per capita measure or a more sophisticated way to take into [...]
