The Behavioral and Welfare Analysis of Consumption covers a wide range of applications using modern parametric and nonparametric econometric techniques related to the behavioural and welfare analysis of consumption. The applications measuring the cost of children, equity and poverty in Colombia are based on the theoretical developments presented in literature during the 1990's. The Behavioral and Welfare Analysis of Consumption places special emphasis on the treatment of demographic characteristics and the interpretation of their effects both in demand and welfare analysis related to the estimation of equivalence scales, social welfare functions and micro-simulations of poverty. The Behavioral and Welfare Analysis of Consumption is a comprehensive and up-to-date reference intended for graduate and advanced undergraduate students interested in the applied fields of consumption economics, welfare economics, development economics and applied econometrics. The contents of the book may be of use also to institutions in the implementation of applied welfare policies of both developed and less developed countries and the analysis of household surveys in general.
