AF Measure Analysis Issues II: Time decompositions of Alkire – Foster measures

Gaston
Yalonetzky

  • Basic time decompositions for cross section data of the censored headcount, the average deprivation score, and the adjusted headcount.
  • Time decompositions for panel datasets introducing transitional probabilities.
  • Empirical examples in both cross section and panel data.
  • Remarks on time comparability in cross section data.

Guide to the video

00:00 Introduction to time decomposition of the censored headcount, the average deprivation score, and the adjusted headcount.

Part 1: Time Decomposition using Cross-Sectional Data

06:22 Introduction to the basic notations

07:25 Basic decomposition of the adjusted headcount,M0

12:39 Basic decomposition of the censored headcount, H

16:05 Basic decomposition of the average deprivation score, A

22:00 Empirical illustration of the basic decomposition using MPI data (Apablaza, M., Ocampo, J.P. , and Yalonetzky, G. (2010))

Part 2: Time Decomposition using Panel Data

38:47 General results of changes in the censored headcount, the average deprivation score, and the adjusted headcount.

41:38 Linking changes over time with transition probabilities (entry and exit into poverty)

46:35 Summary of the transitional probabilities and time changes in some of the main AF components

48:20 Two short cuts between transitional probabilities and time changes

51:57 Empirical illustration using Young Lives Panel dataset (Apablaza, M. and Yalonetzky, G. (2011))
