00:00 Introduction
01:50 Introduction to the concepts of poverty measurement
09:33 Present three types of policy focus of a distribution of achievements; here focus is on the base of the distribution (poverty)
Part 1: Unidimensional Poverty Measures
11:58 Identification: who is poor?
16:37 Significance and definition of poverty line(s)
21:00 Aggregation: What is the level of poverty?
Part 2: Explanation of Axioms (or properties) of Poverty Measures
22:23 The list of axioms from Foster (2006), which properties do you want your measure to have?
24:16 Invariance axioms: symmetry axiom
27:21 Invariance axioms: replication axiom
29:22 Invariance axioms: focus axiom
30:27 Invariance axioms: scale invariance axiom
32:00 Invariance axioms: normalisation axiom
32:56 Dominance axioms: monotonicity axiom
35:48 Dominance axioms: transfer axiom
43:51 Continuity
45:56 Subgroup axioms: introduction
47:30 Subgroup axioms: subgroup consistency
51:16 Subgroup axioms: additive decomposability
53:04 Theorem of Foster and Shorrock for subgroup axioms
53:29 Advanced axiom: transfer sensitivity

00:00 Introduction and classifications of measures (basic and advanced)
Part 1: Basic Unidimensional Measures’ fulfillment of axioms and policy implications
02:27 The headcount ratio
07:11 The income gap ratio
09:59 The poverty gap ratio
21:18 The squared poverty gap
30:23 The Foster-Greer-Thorbecke class of measures, summary of measures
Part 2: Advanced Unidimensional Measures’ fulfillment of axioms
30:50 Sen-Shorrocks-Thon measures
34:07 Watts measure
37:22 Clark-Hemming-Ulph-Chakravarty Class of measures
Part 3: Unidimensional Dominance and Fulfillments of Axioms in Different Orderings
38:24 Which poverty line? (identification)
40:52 Which measure? (aggregation)
42:55 The dominance approach
44:15 Variable-line poverty orderings – order of stochastic dominance developed by Foster and Shorrocks (1988)
45:46 Poverty orderings based on the headcount ratio
49:44 First order stochastic dominance – including definition
52:31 What happens if the cumulative distribution function (CDF) of achievements cross? Second order stochastic dominance – including definition
57:37 What happens when the second order dominance curves cross? Third order stochastic dominance – including definition
59:10 In practice: limited range of poverty orderings
