Book Description
Recent advances in the collective model literature suggest ways to estimate the complete allocation of resources within households, using assignable goods and assuming adult preference similarity across demographic groups (or across spouses). While it makes welfare analysis at the individual level possible, the predictive power of the model is unknown. We propose the first validation of this approach, exploiting a unique dataset from Bangladesh in which the detailed expenditure on private goods by each family member is collected. Individualized expenditure allows us to test the identifying assumptions and to derive ‘observed’ resource sharing within families, which can be compared to the resource allocation predicted by the model. Sharing between parents and children is well predicted on average while the model detects key aspects like the extent of pro-boy discrimination. Results overall depend on the identifying good: clothing provides the best t compared to other goods as it best validates the preference-similarity assumption. The model leads to accurate measures of child and adult poverty, indicating the size and direction of the mistakes made when using the traditional approach based on per adult equivalent expenditure (i.e. ignoring within-household inequality). This assessment of existing approaches to measure individual inequality and poverty is crucial for both academic and policy circles and militates in favor of a systematic use of collective models for welfare analyses.

Book Description
We propose a method to identify bounds (i.e. set identification) on the sharing rule for a general collective household consumption model. Unlike the effects of distribution factors, it is well known that the level of the sharing rule cannot be uniquely identified without strong assumptions on preferences across households of different compositions. Our new results show that, though not point identified without these assumptions, bounds on the sharing rule can still be obtained. We get these bounds by applying revealed preference restrictions implied by the collective model to the household's continuous aggregate demand functions. We obtain informative bounds even if nothing is known about whether each good is public, private, or assignable within the household, though having such information tightens the bounds. An empirical application demonstrates the practical usefulness of our method. -- collective model ; consumer demand ; revealed preferences ; sharing rule ; identification ; bounds

Book Description
Collective Household Consumption Behavior: Revealed Preference Analysis presents a nonparametric `revealed preference' methodology for analyzing collective consumption behavior in practical applications, while possibly accounting for externalities, public consumption and the use of assignable quantity information. Collective Household Consumption Behavior: Revealed Preference Analysis considers two types of collective models: The general collective model considers general preferences of the individual household members, which allow for externalities and public consumption within the household. The special collective models that do not allow for consumption externalities. After the introduction, section 2 sets the stage by introducing the revealed preference characterizations of the unitary model. Section 3 presents a collective model that allows for general individual preferences and discusses its revealed preference characterization. Sections 4 and 5 show how to bring this theoretical characterization to observational data. More specifically, Section 4 introduces the mixed integer programming characterizations for special collective models that impose restrictions on the household members' preferences. Section 5 does the same for the general collective model. Throughout Section 2 to Section 5, the authors illustrate the most relevant concepts by means of numerical examples. In Section 6 we subsequently illustrate our main results for data drawn from the Russian Longitudinal Monitoring Survey.

Book Description
The World Bank Group has two overarching goals: End extreme poverty by 2030 and promote shared prosperity by boosting the incomes of the bottom 40 percent of the population in each economy. As this year’s Poverty and Shared Prosperity report documents, the world continues to make progress toward these goals. In 2015, approximately one-tenth of the world’s population lived in extreme poverty, and the incomes of the bottom 40 percent rose in 77 percent of economies studied. But success cannot be taken for granted. Poverty remains high in Sub- Saharan Africa, as well as in fragile and conflict-affected states. At the same time, most of the world’s poor now live in middle-income countries, which tend to have higher national poverty lines. This year’s report tracks poverty comparisons at two higher poverty thresholds—$3.20 and $5.50 per day—which are typical of standards in lower- and upper-middle-income countries. In addition, the report introduces a societal poverty line based on each economy’s median income or consumption. Poverty and Shared Prosperity 2018: Piecing Together the Poverty Puzzle also recognizes that poverty is not only about income and consumption—and it introduces a multidimensional poverty measure that adds other factors, such as access to education, electricity, drinking water, and sanitation. It also explores how inequality within households could affect the global profile of the poor. All these additional pieces enrich our understanding of the poverty puzzle, bringing us closer to solving it. For more information, please visit worldbank.org/PSP

Book Description
The search for a robust and stable sharing rule has led us to novel results about identification of the rule governing the intra-household allocation of resources. We introduce an income proportionality property that directly connects distribution factors with individual incomes and implement this identifying condition to obtain an exact correspondence between the structural and reduced form of the adopted collective demand equations. The paper first reexamines the collective model of household consumption and shows that a) the collective model as traditionally developed is not identified, b) illustrates the novel income proportionality condition, and c) derives a restriction allowing full identification. In the tradition of collective theory, we exploit information about private consumption of an assignable good, clothing for adults and children in our application, prices and distribution factor variation to estimate how resources are shared between adults and children in a sample of Italian households. Previous estimations of collective models where only limited to either the direct or indirect estimation of the structure. Our results open up the possibility of a direct structural estimation of a collective system of demand equations, and associated individual Engel curves, as easily as estimating a demand system based on a unitary framework.
