Well-being in Belgium : Beyond Happiness and Income by Bart Capéau( )

6 editions published in 2020 in English and held by 205 WorldCat member libraries worldwide

What constitutes a good life? For most people, well-being involves more than a high income or material prosperity alone. Many non-material aspects, such as health, family life, living environment, job quality and the meaningful use of time are at least as important. Together, these factors also influence the degree to which people are satisfied with their lives, and help to determine how happy they feel. This book argues that happiness and life satisfaction do not form a good basis for measuring well-being, and proposes an alternative method that not only considers the various aspects of well-being, but also the fact that people have their own views on what is important in life. Not limited just to theory, the book also presents a large-scale, representative survey involving more than 3000 adults from over 2000 Belgian families, which charted the various aspects of the individual well-being of Belgians. Focusing on the unequal distribution of these various aspects of well-being within families, the survey showed that some Belgians are more likely to suffer from cumulative deprivation in multiple dimensions. Based on this innovative study, the book describes which people in society are worst off - and these are not necessarily only people on low incomes or those who feel unhappy - and proposes that policymakers prioritise these individuals
Collective household consumption behavior : revealed preference analysis by Laurens Cherchye( )

9 editions published between 2010 and 2014 in English and held by 49 WorldCat member libraries worldwide

We review a nonparametric "revealed preference" methodology for analyzing collective consumption behavior in practical applications. The methodology allows for accounting for externalities, public consumption, and the use of assignable quantity information in the consumption analysis. This provides a framework for empirically assessing welfare-related questions that are specific to the collective model of household consumption. As a first step, we discuss the testable necessary and sufficient conditions for data consistency with special cases of the collective model (e.g., the case with all goods publicly consumed, and the case with all goods privately consumed without externalities); these conditions can be checked by means of mixed integer (linear) programming (MIP) solution algorithms. Next, we focus on a testable necessary condition for the most general model in our setting (i.e., the case in which any good can be publicly consumed as well as privately consumed, possibly with externalities); again, this condition can be checked by means of MIP solution algorithms. Even though this general model imposes minimal structure a priori, we show that the MIP characterization allows for deriving bounds on the feasible income shares. Finally, we illustrate our methods by some empirical applications to data drawn from the Russian Longitudinal Monitoring Survey
Analyzing Cost Efficient Production Behavior Under Economies of Scope A Nonparametric Methodology by Laurens Cherchye( )

6 editions published in 2006 in English and Undetermined and held by 20 WorldCat member libraries worldwide

"In designing a production model for firms that generate multiple outputs, we take as a starting point that such multi-output production refers to economies of scope, which in turn originate from joint input use and input externalities. We provide a nonparametric characterization of cost efficient behavior under these conditions, and subsequently institute necessary and sufficient conditions for data consistency with such efficient behavior that only include observed firm demand and supply data. We illustrate our methodology by examining the cost efficiency of research programs in Economics and Business Management faculties of Dutch universities. This application shows that the proposed methodology may entail robust conclusions regarding cost efficiency differences between universities within specific specialization areas, even when using shadow prices to evaluate the different inputs"--Forschungsinstitut zur Zukunft der Arbeit web site
The revealed preference approach to collective consumption behavior : testing, recovery and welfare analysis by Laurens Cherchye( )

5 editions published in 2007 in English and Undetermined and held by 19 WorldCat member libraries worldwide

"We extend the nonparametric 'revealed preference' methodology for analyzing collective consumption behavior (with consumption externalities and public consumption), to render it useful for empirical applications that deal with welfare-related questions. First, we provide a nonparametric necessary and sufficient condition for collectively rational group behavior that incorporates the possibility of assignable quantity information. This characterizes collective rationality in terms of feasible personalized prices, personalized quantities and income shares (representing the underlying sharing rule). Subsequently, we present nonparametric testing tools for data consistency with special cases of the collective model, which impose specific structure on the preferences of the group members (in terms of consumption externalities and public consumption); and we show that these testing tools in turn allow for nonparametrically recovering (bounds on) feasible personalized prices, personalized quantities and income shares that underlie observed (collectively rational) group behavior. In addition, we present formally similar testing and recovery tools for the general collective consumption model, which imposes minimal a priori structure. Interestingly, the proposed testing and recovery methodology can be implemented through integer programming (IP and MILP), which is attractive for practical applications. Finally, while we argue that assignable quantity information generally entails more powerful recovery results, we also demonstrate that precise nonparametric recovery (i.e. tight bounds) can be obtained even if no assignable quantity information is available"--Forschungsinstitut zur Zukunft der Arbeit web site
Married with children a collective labor supply model with detailed time use and intrahousehold expenditure information by Laurens Cherchye( )

4 editions published in 2010 in English and held by 18 WorldCat member libraries worldwide

We propose a collective labor supply model with household production that generalizes an original model of Blundell, Chiappori and Meghir (2005). In our model, adults' individual preferences do not only depend on own leisure and individual private consumption of market goods. They also depend on the consumption of domestic goods, which are produced by combining goods bought at the market with individuals' time. We apply our model to new and unique data on Dutch couples with children. The data contains detailed information about the spouses' time use and the intrahousehold allocation of all expenditures. Our application uses a novel estimation strategy that builds upon the familiar two-stage allocation representation of the collective model. We obtain interesting (and plausible) empirical results. Spouses'; preferences depend on the consumption of domestically produced goods (including children's welfare). Next, Pareto weights depend on variables like the individual wages and the share in the household's nonlabor income. Finally, and perhaps surprisingly, we do not find evidence that mothers care more for their children than fathers. -- collective model ; labor supply ; time use ; public goods ; household production
An Afriat Theorem for the Collective Model of Household Consumption by Laurens Cherchye( )

4 editions published in 2008 in English and Undetermined and held by 18 WorldCat member libraries worldwide

We provide a nonparametric 'revealed preference' characterization of rational household behavior in terms of the collective consumption model, while accounting for general (possibly non-convex) individual preferences. We establish a Collective Axiom of Revealed Preference (CARP), which provides a necessary and sufficient condition for data consistency with collective rationality. Our main result takes the form of a 'collective' version of the Afriat Theorem for rational behavior in terms of the unitary model. This theorem has some interesting implications. With only a finite set of observations, the nature of consumption externalities (positive or negative) in the intra-household allocation process is non-testable. The same non-testability conclusion holds for privateness (with or without externalities) or publicness of consumption. By contrast, concavity of individual utility functions (representing convex preferences) turns out to be testable. In addition, monotonicity is testable for the model that assumes all household consumption is public
Opening the black box of intra-household decision-making: theory and non-parametric empirical tests of general collective consumption models by Laurens Cherchye( )

6 editions published in 2005 in English and held by 6 WorldCat member libraries worldwide

We non-parametrically test a general collective consumption model with public consumption and externalities inside the household. We further propose a novel approach to model special cases of the general collective model. These special cases include alternative restrictions on the 'sharing rule' that applies to each household, and which defines the distribution of the household budget over the household members. A limiting case is the unitary model. Our application uses data from the Russia Longitudinal Monitoring Survey (RLMS); the panel structure of this data set allows non-parametric testing of the behavioral models without relying on preference homogeneity assumptions across similar individuals. This application includes test results but also a power analysis for different specifications of the collective consumption model. Our main findings are that the most general collective model, together with a large class of special but still fairly general cases, cannot be rejected by the data, while other, restricted, versions of the general model, including the unitary alternative, are rejected. Since these tests are entirely non-parametric, this provides strong evidence in favor of models focusing on intra-household decision-making. -- collective househould models ; intra-household allocation ; revealed preferences ; non-parametric analysis
A new year, a new you? : Heterogeneity and self-control in food purchases by Laurens Cherchye( Book )

3 editions published in 2017 in English and held by 6 WorldCat member libraries worldwide

"We document considerable within-person (over time) variation in diet quality that is not fully explained by responses to fluctuations in the economic environment. We propose a two-selves model that provides a structural interpretation to this variation, in which food choices are a compromise between a healthy and an unhealthy self, each with well-behaved preferences. We show that the data are consistent with this model using revealed preference methods. The extent of self-control problems is higher among younger and lower income consumers, though this is overstated if we do not control for responses to fluctuations in the economic environment. Our results are intuitively related to stated attitudes on self-control."--Abstract
Aggregation without the Aggravation? Nonparametric Analysis of the Representative Consumer( )

3 editions published in 2011 in English and German and held by 4 WorldCat member libraries worldwide

In the tradition of Afriat (1967), Diewert (1973) and Varian (1982), we provide a revealed preference characterisation of the representative consumer. Our results are simple and complement those of Gorman (1953, 1961), Samuelson (1956) and others. They can also be applied to data very readily and without the need for auxilliary parametric or statistical assumptions. We investigate the application of our characterisation by means of a balanced microdata panel survey. Our findings provide robust evidence against the existence of a representative consumer for our data
Economic well-being and poverty among the elderly an analysis based on a collective consumption model by Laurens Cherchye( )

4 editions published between 2008 and 2014 in English and Undetermined and held by 4 WorldCat member libraries worldwide

We apply the collective consumption model of Browning, Chiappori and Lewbel (2006) to analyse economic well-being and poverty among the elderly. The model focuses on individual preferences, a consumption technology that captures the economies of scale of living in a couple, and a sharing rule that governs the intra-household allocation of resources. The model is applied to a time series of Dutch consumption expenditure surveys. Our empirical results indicate substantial economies of scale and a wife's share that is increasing in total expenditures.We further calculated poverty rates by means of the collective consumption model. Collective poverty rates of widows and widowers turn out to be slightly lower than traditional ones based on a standard equivalence scale. Poverty among women (men) in elderly couples, however, seems to be heavily underestimated (overestimated) by the traditional approach. Finally, we analysed the impact of becoming a widow(er). Based on cross-sectional evidence, we find that the drop (increase) in material well-being following the husband's death is substantial for women in high (low) expenditure couples. For men, the picture is reversed
Sharing rule identification for general collective consumption models( )

3 editions published in 2012 in English and German and held by 4 WorldCat member libraries worldwide

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
Heuristics for Deciding Collectively Rational Consumption Behavior by Fabrice Talla Nobibon( )

2 editions published between 2008 and 2010 in Undetermined and English and held by 3 WorldCat member libraries worldwide

We consider the computational problem of testing whether observed household consumption behavior satisfies the Collective Axiom of Revealed Preferences (CARP). We propose a graph such that the existence of a node-partitioning giving rise to two induced subgraphs that are acyclic implies that the data satisfy CARP. Furthermore, we propose and implement heuristics that are quite fast, that can be used to check reasonably large datasets for CARP and that can be of particular interest when used prior to computationally demanding approaches. Finally, from the computational results we conclude that these heuristics can be effective in testing CARP
The Collective Model of Household Consumption A Nonparametric Characterization by Laurens Cherchye( )

3 editions published between 2004 and 2005 in English and Undetermined and held by 3 WorldCat member libraries worldwide

We provide a nonparametric characterization of a general collective model for multi-person household consumption, which includes externalities and public goods. We derive the minimum number of commodities and observations that enable the falsification of this general model for aggregrate household quantity and price data; these requirements are generally less stringent than the conditions derived by Browning and Chiappori (1998) within a parametric setting. Next, we institute necessary and sufficient conditions for data consistency with collective rationality that only include observed price and quantity information. These conditions are formally similar to the GARP condition for the unitary model (see Varian, 1982); which is particularly convenient from a practical point of view. To illustrate the generality of the collective model, we also discuss a number of interesting special cases, including the traditional unitary model and the collective labor supply a la Chiappori (1988)

Stable marriage, household consumption and unobserved match quality by Martin Browning( )

3 editions published in 2021 in English and held by 3 WorldCat member libraries worldwide

We present a methodology for the structural empirical analysis of household consumption and time use behaviour under marital stability. Our approach is of the revealed preference type and non-parametric, meaning that it does not require a prior functional specification of individual utilities. Without making use of the transferable utility assumption, but still allowing for monetary transfers, our method can identify individuals' unobserved match qualities and quantify them in money metric terms. We can include both preference factors, affecting individuals' preferences over private and public goods, and match quality factors, driving differences in unobserved match quality. We demonstrate the practical usefulness of our methodology through an application to the Belgian MEqIn data. Our results reveal intuitive patterns of unobserved match quality that allow us to rationalise both the observed matches and the within-household allocations of time and money
En faut-il peu pour être heureux? : conditions de vie, bonheur et bien-être en Belgique by Bart Capéau( Book )

2 editions published in 2019 in French and held by 2 WorldCat member libraries worldwide

Qu'est-ce qu'une belle vie? Pour la plupart des gens, la notion de bien-être s'étend au-delà de la richesse financière ou matérielle. En effet, beaucoup d'aspects non matériels, tels que la santé, la vie de famille, le cadre de vie, la répartition du temps et la qualité du travail, sont au moins aussi importants. Tous ces aspects influencent la mesure dans laquelle les gens sont satisfaits de leur vie et se sentent heureux. Dans ce livre, les auteurs soutiennent toutefois que le bonheur et la satisfaction à l'égard de la vie ne sont pas de bons indicateurs pour la mesure du bien-être. Ils proposent une méthode alternative, celle du revenu équivalent, tenant non seulement compte des différentes dimensions du bien-être, mais également de l'opinion qu'ont les individus quant à ce qui est important dans leur propre vie. Le livre ne se base pas que sur de la théorie. Une enquête à grande échelle menée auprès d'un échantillon représentatif de plus de 3.000 adultes issus de 2.000 familles belges a permis de décrire de manière détaillée les différents aspects du bien-être individuel des Belges. Son originalité réside dans l'attention portée à la répartition inégale de différents aspects du bien-être au sein même des familles. Il ressort de l'enquête que certains Belges cumulent des désavantages dans plusieurs dimensions du bien-être. La méthode du revenu équivalent permet d'identifier les personnes les plus démunies dans notre société, qui ne s?avèrent pas nécessairement être celles qui perçoivent les revenus les plus faibles ni les plus malheureuses. Ces personnes méritent, selon les auteurs, une attention particulière de la part des responsables politiques
