Abstract:
Women are disproportionately in low‐paid work compared to men so, in the absence of rationing effects on their employment, they should benefit the most from minimum wage policies. This study examines the change in the gender wage gap around the introduction of minimum wages in Ireland and the United Kingdom (U.K.). Using survey data for the two countries, we develop a decomposition of the change in the gender differences in wage distributions around the date of introduction of minimum wages. We separate out price effects attributed to minimum wages from employment composition effects. A significant reduction of the gender gap at low wages is observed after the introduction of the minimum wage in Ireland, while there is hardly any change in the U.K. Counterfactual simulations show that the difference between countries may be attributed to gender differences in non‐compliance with the minimum wage legislation in the U.K.

Abstract:
Relatively few studies have examined the physical health of children who experience parental separation. The few studies on this topic have largely focused on the United States and have used cross-sectional designs. Our study investigates the relationship between parental separation and children’s body mass index (BMI) and overweight/obesity risk using the UK Millennium Cohort Study. Treating parental separation as a process, we analyze variations in children's physical health before and after the date of their parents' separation in order to capture potential anticipation, adaptation, delayed, or cumulative effects. We estimate fixed-effects models to account for the potential correlation between children's physical health and unobserved factors associated with parental separation, such as socioeconomic background and other time-invariant parental characteristics. We find no evidence of statistically significant anticipation effects in the build-up to parental separation or of statistically significant changes in children’s physical health immediately after separation. However, our results show that in the longer term, the BMI of children whose parents separate significantly deviates from the BMI of children from intact families. Furthermore, this association is especially strong for separations that occur when children are under age 6.

Abstract:
This paper proposes a framework for studying international differences in the distribution of household income. Integrating micro-econometric and micro-simulation approaches in a decomposition analysis it quantifies the role of tax-benefit systems, employment and occupational structures, labour prices and market returns, and demographic composition in accounting for differences in income inequality across countries. Building upon EUROMOD (the European tax-benefit calculator) and its harmonized datasets, the model is portable and can be implemented for any cross-country comparisons within the EU. An application to the UK and Ireland--two countries that have much in common while displaying different levels of inequality--shows that differences in tax-benefit rules between the two countries account for roughly half of the observed difference in disposable household income inequality. Demographic differences play negligible roles. The Irish tax-benefit system is more redistributive than UK's due to a higher tax progressivity and higher average transfer rates. These are largely attributable to policy parameter differences, but also to differences in pre-tax, pre-transfer income distributions.

(2018), 'Macroprudential policy and household wealth inequality', Journal of International Money and Finance, 85(C), 262-277.
     

Abstract:
Macroprudential policies, such as caps on loan-to-value (LTV) ratios, have become part of the policy paradigm in emerging markets and advanced countries alike. Given that housing is the most important asset in household portfolios, relaxing or tightening access to mortgages may affect the distribution of household wealth in the country. In a stylised model we show that the final level of wealth inequality depends on the size of the LTV ratio, housing prices, credit cost and the strength of a bequest motive, and therefore it is not possible to predict an unequivocal effect of LTV ratios on wealth inequality. These trade-offs are illustrated with estimations of `Gini Recentered Influence Function' regressions on household survey data from 12 Euro-zone countries that participated in the first wave of the Household Finance and Consumption Survey. The results show that, among the households with active mortgages, high LTV ratios at the time of acquisition are related to high contributions to wealth inequality today, while house price increases are negatively related to inequality contributions. A proxy for the strength of bequest motives tends to be negatively related with wealth inequality, but credit cost does not show a significant link to the distribution of wealth.

Abstract:
The paper exploits large-scale administrative data to analyse trends in male earnings inequality in Luxembourg during 20 years of rapid economic growth, industrial redevelopment and massive inflow of foreign workers. A detailed error components model is estimated to identify persistent and transitory components of (the trends of) log-earnings variance and to disentangle the contributions to it of native, immigrant and cross-border workers. The model is flexible and allows for a high degree of individual, age, time and cohort heterogeneity. We observe a surprising stability in overall earnings inequality as a result of more complex underlying changes, with marked increases in persistent inequality (except among natives), a growing contribution of foreigners and a decrease in earnings instability (primarily for natives).

Abstract:
This paper documents the change in educational achievement differences between native and foreign background students between the ages of 10 and 15, as they progress from primary to secondary education. We examine three cohorts of students in a number of Western European and traditional English-speaking immigration countries using combinations of PIRLS, TIMSS and PISA survey data. While the performance of students with mixed parents is not markedly different from native students', foreign background children--both first- and second-generation--exhibit a large achievement gap at age 10 in continental Europe, even when accounting for observable differences in socio-economic characteristics. The gap tends to narrow down by age 15 in reading, but no catching up is observed in mathematics. By contrast, we do not find significant differences between the academic achievements of immigrant children and their native-born peers in traditional immigration countries.

Abstract:
This paper draws upon influence function regression methods to determine where foreign workers stand in the distribution of private sector wages in Luxembourg, and assess whether and how much their wages contribute to wage inequality. This is quantified by measuring the effect that a marginal increase in the proportion of foreign workers—foreign residents or cross-border workers—would have on selected quantiles and measures of inequality. Analysis of the 2006 Structure of Earnings Survey reveals that foreign workers have generally lower wages than natives and therefore tend to haul the overall wage distribution downwards. Yet, their influence on wage inequality reveals small and negative. All impacts are further muted when accounting for human capital and, especially, job characteristics. Not observing any large positive inequality contribution on the Luxembourg labour market is a striking result given the sheer size of the foreign workforce and its polarization at both ends of the skill distribution.

Abstract:
Among the primary EU indicators of social inclusion is the persistent at risk of poverty rate, defined as the proportion of persons in a country who are at risk of income poverty in the current year and who were at risk of income poverty in at least two of the preceding three years. Evidence about poverty persistence is an important complement to information about poverty prevalence at a point in time. Estimates of persistent at risk of poverty rates are derived from the longitudinal component of EU SILC in which the fortunes of individuals are tracked over four consecutive years, in principle. In practice, not all of the individuals present in the first sample year provide four years of income data: there is attrition and estimates of persistent at risk of poverty measure may therefore not be reliable. Rates of attrition from the four-year EU SILC samples used to calculate persistent poverty rates vary substantially across Member States, and there is also substantial cross-national diversity in the characteristics of individuals lost to follow-up. This paper documents such patterns in detail and provides evidence that application of longitudinal weights does not fully account for the effects of attrition, and that different assumptions about the poverty status of attritors lead to wide bounds for estimates of persistent poverty rates for most Member States.

(2017), 'Measuring and accounting for the deprivation gap of Portuguese immigrants in Luxembourg', Review of Income and Wealth, 63(2), 288-309.
     

Abstract:
This paper examines the relative well-being of Portuguese immigrants in Luxembourg by looking at indicators of material deprivation. We document material deprivation differences between immigrants and nationals---the `deprivation gap'---and measure the extent to which income differentials (and other sociodemographic differences) explain this gap using a combination of non-parametric methods and a versatile graphical device. We find a large and significant deprivation gap against Portuguese immigrants, whatever the indicator considered. The extent to which the gap is merely a reflection of differences in income, however, depends on what deprivation items are taken into consideration. Income differences almost fully account for material deprivation differences when the latter is measured using the items included in the official EU social indicator of material deprivation. Inclusion of housing condition indicators mitigates this relationship and we then find compelling evidence that the deprivation gap is not entirely accounted for by income differentials.

Abstract:
Although it is heartening to see wealth inequality being taken seriously, key concepts are often muddled, including the distinction between income and wealth, what is included in !wealth!, and facts about wealth distributions. This chapter highlights issues that arise in making ideas and facts about wealth inequality precise, and employs newly-available data to take a fresh look at wealth and wealth inequality in a comparative perspective. The composition of wealth is similar across countries, with housing wealth being the key asset. Wealth is considerably more unequally distributed than income, and it is distinctively so in the United States. Extending definitions to include pension wealth however reduces inequality substantially. Analysis also sheds light on life-cycle patterns and the role of inheritance. Discussion of the joint distributions of income and wealth suggests that interactions between increasing top income shares and the concentration of wealth and income from wealth towards the top is critical.

Abstract:
We develop methods for describing distributions of income growth across individuals and for comparing changes in growth distributions over time. The methods include graphical devices (‘income growth profiles’) and dominance conditions, and also summary indices, together with associated methods of estimation and inference. Taking an explicitly longitudinal perspective, our approach illuminates clearly who are the gainers and the losers, and also provides distributionally-sensitive assessments—ones that allow the income growth for different individuals to be weighted differently. Our empirical application shows that the pattern of income growth in Britain over the period 1992–6 was less pro-poor than that for 1998–2002, and not significantly different from the pattern for 2001–5.

(2016), 'Minimum wages and the gender gap in pay. Evidence from the UK and Ireland', LISER Working Paper 2016-02, Luxembourg Institute of Socio-Economic Research, Esch-sur-Alzette, Luxembourg.
     

Abstract:
Since women are disproportionately in low paid work, they should benefit the most from minimum wage policies. We exploit the introduction of a national minimum wage (MW) in Ireland (in 2000) and the UK (in 1999) to check this prediction. Using panel survey data, we implement difference-in-difference estimation of a distribution regression model. We separate out ``price'' effects from ``composition'' effects. A large reduction of the gap at low wages is found for Ireland, with small spill-over effects further up in the distribution. There is hardly any effect in Britain, largely because of apparent gender-biased non-compliance with the minimum wage legislation.

Abstract:
The paper develops a parametric variant of the Machado–Mata simulation methodology to examine quantile wage differences between groups of workers, with an application to the wage gap between native and foreign workers in Luxembourg. Relying on conditional-likelihood-based ‘parametric quantile regression’ in place of the standard linear quantile regression is parsimonious and cuts computing time drastically with no loss in the accuracy of marginal quantile simulations in our application. We find that the native worker advantage is a concave function of quantile: the advantage is small (possibly negative) for both low and high quantiles, but it is large for the middle half of the quantile range (between the 20th and 70th native wage percentiles).

Abstract:
This paper provides a new examination of the gender pay gap for Germany based on a family of distribution-sensitive indicators. Wage distributions for men and women do not only differ by a fixed constant; differences are more complex. We show that focusing on the bottom of the wage distribution reveals a larger gender gap. Our distribution-sensitive analysis can also be used to study whether the statistical disadvantage of women in average pay might be ‘offset’ by lower inequality. Over a broad range of plausible preferences over inequality, we show however that ‘inequality-adjusted’ estimates of the gap can be up to three times higher than standard inequality-neutral measures in Eastern Germany and up to fifty percent higher in Western Germany. Using preference parameters elicited from a hypothetical risky investment question in our sample, inequality-adjusted gender gap measures turn out to be close to those upper bounds.

Abstract:
This paper considers a parametric model for the joint distribution of income and wealth. The model is used to analyze income and wealth inequality in five OECD countries using comparable household-level survey data. We focus on the dependence parameter between the two variables and study whether accounting for wealth and income jointly reveals a different pattern of social inequality than the traditional “income only” approach. We find that cross-country variations in the dependence parameter effectively account only for a small fraction of cross-country differences in a bivariate measure of inequality. The index appears primarily driven by differences in inequality in the wealth distribution.

Abstract:
The current poverty rate and the persistent poverty rate are both included in the EU's portfolio of primary indicators of social inclusion. We show that there is a near-linear relationship between these two indicators across EU countries drawing on empirical analysis of EU-SILC and ECHP data. Using a prototypical model of poverty dynamics, we explain how the near-linear relationship arises and show how the model can be used to predict persistent poverty rates from current poverty information. In the light of the results, we discuss whether the EU's persistent poverty measure and the design of EU-SILC longitudinal data collection require modification.

Abstract:
Luxembourg experienced remarkable economic performance and employment growth since the middle of the 1980s. Based on the development of the financial sector, this growth benefited massively from the contribution of immigrants and cross-border workers to the labour force. High economic growth led to a rapid improvement in the overall living standard of the resident population. During the same period, income inequality increased too, albeit modestly. Even if the country can still be considered a low inequality country by international standards, this trend is a potential source of concern. This chapter analyses the factors that explain the rise in income inequality between 1985 and 2010 and provides a descriptive account of whether this trend has been correlated with a set of social, cultural, and political outcomes. By and large, the positive impact of the improvement of overall living standards seems to have prevailed over the potential detrimental effects of increasing inequality.

Abstract:
This paper considers measures of wage differentials not solely determined by mean comparisons but summarizing differences across complete wage distributions. The approach builds on considerations of risk or inequality aversion and on standard expected utility concepts. In an application to the gender pay gap in Luxembourg the disadvantage of women persists according to the proposed measures: lower mean wages for women are not compensated by differences in higher moments of wage distributions (e.g., by less dispersion) at least for realistic assumptions about women preferences toward risk and inequality. The paper also illustrates an original empirical model for wage distributions in the presence of covariates and under endogenous labour market participation.

Abstract:
This paper exploits EU Statistics on Income and Living Conditions longitudinal data 2003–2007 to describe the intertemporal distribution of income in twenty-six European countries prior to the onset of the Great Recession. We document levels, inequality and progressivity in the distribution of year-on-year income gains and losses and examine the relationship of these with inequality and poverty indicators. New Member States have typically seen individual incomes grow faster than other EU countries. Income gains were disproportionately pro-poor in all countries. We therefore observe regression to the mean both among EU countries and among individuals within countries. However, short-run income mobility does not significantly reduce inequality of time-averaged incomes. Potential issues about cross-country comparability of the data and the short period under consideration call for caution in interpreting our results, however.

Abstract:
The persistent at-risk-of-poverty rate is one of the EU's 11 primary indicators of social inclusion but it has received little attention compared to the current at-risk-of-poverty rate. Using the 2008 EU Statistics on Income and Living Conditions (EU-SILC) database, we compare persistent income poverty rates across European nations and examine differences in poverty profiles for subgroups defined by age and sex. We draw attention to similarities between the profiles for persistent at-risk-of-poverty rates and at-risk-of-poverty rates, and are led to question the relevance of the former measure in its current form as a key EU indicator of social progress.

Abstract:
Evidence of the association between wages and body size –typically measured by the body mass index– appears to be sensitive to estimation methods and samples, and varies across gender and ethnic groups. One factor that may contribute to this sensitivity is the non-linearity of the relationship. This paper analyzes data from the European Community Household Panel survey and uses semi-parametric techniques to avoid functional form assumptions and assess the relevance of standard models. If a linear model for women and a quadratic model for men fit the data relatively well, they are not entirely satisfactory and are statistically rejected in favour of semiparametric models which identify patterns that none of the parametric specifications capture. Furthermore, when we use height and weight in the models directly, rather than equating body size with the body mass index, the semi-parametric models reveal a more complex picture with height having additional effects on wages. We interpret our

Abstract:
We examine the effect of income inequality on individualś self-rated health status in a pooled sample of 11 countries, using longitudinal data from the European Community Household Panel survey. Taking advantage of the longitudinal and cross-national nature of our data, and carefully modeling the self-reported health information, we avoid several of the pitfalls suffered by earlier studies on this topic. We calculate income inequality indices measured at two standard levels of geography (NUTS-0 and NUTS-1) and find consistent evidence that income inequality is negatively related to self-rated health status in the European Union for both men and women, particularly when measured at national level. However, despite its statistical significance, the magnitude of the impact of inequality on health is very small.

Abstract:
We develop an integrated framework for studying income convergence that incorporates traditional measures of beta-convergence and sigma-convergence. These concepts are formally linked by a measure of re-ranking (or leapfrogging). Our proposed measure of beta-convergence allows for nonlinearities in the growth process and explicitly identifies the contribution of faster growth among low-income regions to reductions in overall inequality. To develop our framework we exploit the close links that exist between studies of income convergence and studies that examine the progressivity of the tax system. We illustrate our approach by examining both cross-country and regional income dynamics.

Abstract:
Micro-data estimates of welfare indices are known to be sensitive to observations from the tails of the income distribution. It is therefore customary to make adjustments to extreme data before estimating inequality and poverty statistics. This paper systematically evaluates the impact of such adjustments on indicators estimated from the EU-SILC (Community Statistics on Income and Living conditions) which is expected to become the reference source for comparative statistics on income distribution and social exclusion in the EU. Emphasis is put on the robustness of cross-country comparisons to alternative adjustments. Results from a sensitivity analysis considering both simple, classical adjustments and a more sophisticated approach based on modelling parametrically the tails of the income distribution are reported. Reassuringly, ordinal comparisons of countries are found to be robust to variants of data adjustment procedures. However, data adjustments are far from innocuous. Cardinal comparisons of countries reveal sensitive to the treatment of extreme incomes, even for seemingly small adjustments.

Abstract:
We provide an analytical framework within which changes in income inequality over time are related to the pattern of income growth across the income range and the reshuffling of individuals in the income pecking order. We use the framework first to explain how it was possible both for the poor to have fared badly relatively to the rich in the USA during the 1980s (when income inequality grew substantially), and also for income growth to have been pro-poor. Second, we contrast the US experience with that of Western Germany, where there was a much smaller rise in inequality. This is accounted for by income growth that was more pro-poor than in the USA.

Abstract:
This paper develops methods for decomposing changes in the income distribution using subgroup decompositions of the income density function. Overall changes are related to changes in subgroup shares and changes in subgroup densities, where the latter are broken down further using elementary transformations of individual incomes. These density decompositions are analogous to the widely-used decompositions of inequality indices by population subgroup, except that they summarize multiple features of the income distribution (using graphs), rather than focusing on a specific feature such as dispersion, and are not dependent on the choice of a specific summary index. Nonetheless, since inequality and poverty indices can be expressed as PDF functionals, our density-based methods can also be used to provide numerical decompositions of these. An application of the methods reveals the multi-faceted nature of UK income distribution trends during the 1980s.

Les estimations révèlent que cette sophistication est nécessaire car un effet de sélection endogène est présent. On observe une grande diversité des risques estimés de persistance et d'entrée dans la pauvreté. L'accès à un revenu du travail, le niveau d'éducation et l'âge sont les facteurs qui semblent influencer le plus fortement les risques de d'entrée et de sortie de la pauvreté. A l'inverse, le sexe et la nationalité ne semblent pas avoir d'effet propre substantiel. On observe également un effet de dépendance à la pauvreté: la pauvreté aujourd'hui à un effet propre important sur les chances de pauvreté demain.

Abstract:
The paper presents a decomposition of income mobility indices into two basic sources: Mobility induced by a change of the income distribution shape and mobility induced by a re-ordering of individuals in the income pecking order. The decomposition procedure based on counterfactual distributions results in a decomposition that is applicable to a broad class of mobility measures. Application to income `movement' indices with data for Belgium, Western Germany and the USA indicates that reranking has been the major force behind income mobility.

Abstract:
This paper offers an exploratory analysis of household income volatility in the 1990s in fourteen EU countries and two future member states, namely Hungary and Poland, using simple summary statistics for average income changes as advocated in Fields and Ok (JET 1996, Economica 1999). The evidence is derived from the newly generated data of the Consortium of Household Panels for European Socio-Economic Research (CHER) that contain harmonised data from the European Community Household Panel and from a series of independent panel surveys. Going a step ahead to overcome the obvious restriction of looking only at population averages as Fields and Ok suggest, both the overall distribution of individual income variations, and the variations in levels of income volatility for different starting income levels are also examined. The analysis can be viewed as looking at the primitives of income mobility at the individual level, as opposed to many of the existing analyses that assess, using other more sophisticated concepts, the aggregate outcome (like inequality of long-term income) resulting from these individual income variations.

Abstract:
This paper documents the magnitude of income mobility in Germany and its distribution across different income positions, using data from the German Socio-Economic Panel. The suggested graphical approach makes it straightforward to identify the portions of the distribution that have the largest impact on aggregate `income movement' indices a la Fields and Ok, and hence offers a starting point to help account for income mobility levels. It appears that most of the contribution to mobility is made by the poorest 10% of the initial distribution. Average relative income changes are much lower and generally constant for the rest of the population.

Abstract:
Two broad types of method tend to be used to estimate the sampling distribution of inequality measure estimators: analytical asymptotic approximations and resampling-based procedures (e.g. thebootstrap). The present paper attempts to check the coverage performance, in large samples, of a series of standard estimators of both types so as to provide a yardstick to choose among competing alternatives. Two sampling schemes are considered: simple random sampling and clustered sampling. The comparison is made using a Monte Carlo experiment and an application to Belgian data. It turns out that neither basic bootstrap procedures nor asymptotic approximations significantly outperform its competitors. Both yield acceptable estimates (especially in random samples) provided that sampling design is taken into account.

Abstract:
Although the requisite data are available, information about low income dynamics in Belgium is in short supply. This article presents new evidence based on the first six waves of a nationally representative panel survey: the Panel Study on Belgian Households (PSBH). The basic figures reported suggest that the degree of low income turnover in Belgium is relatively low. However the picture obtained crucially depends on the poverty threshold considered with the turnover being much higher at the very bottom of the income distribution. Re-entry into poverty turns out to be an important risk, even after several years spent out of poverty. More generally, cross-sections of the population seem to provide a fairly good proxy for those ‘persistently’ poor.

Abstract:
Le caractère longitudinal du Panel Study on Belgian Households permet de suivre un échantillon d'individus au cours du temps et de voir si ce sont les mêmes personnes qui se trouvent en situation de pauvreté année après année ou si au contraire il y a un renouvellement de la population pauvre. Il apparaît qu’il y a un renouvellement important dans la pauvreté. Cependant, l'évaluation dépend fortement du niveau de la ligne de pauvreté choisie. Généralement, les groupes identifiés à risque en coupe transversale se révèlent aussi à risque si l'on se focalise sur la persistance dans la pauvreté. Il faut noter que la différenciation entre les groupes « à risque » se marque plus lorsque l’on élève la ligne de pauvreté. Sans surprise, l'accès au marché du travail se révèle être un déterminant important de la pauvreté et de la persistance dans celle-ci.

Abstract:
Deuxième complément à l'excellent ouvrage de Hal Varian Introduction à la microéconomie, ce manuel propose un nouveau choix d'exercices visant à favoriser l'apprentissage de la modélisation microéconomique moderne par les étudiants du premier et du second cycle en économie. L'effort pédagogique des auteurs se manifeste dans la diversité et l'originalité des thèmes abordés et dans le soin apporté à la cohérence de l'ouvrage. Dans ce second tome, les matières couvertes portent, entre autres, sur la théorie des choix intertemporels et en incertitude, le marché des actifs, la théorie des jeux, le bien-être, les externalités et les biens publics ainsi que la théorie de l'information.

Abstract:
L'objectif de cette étude est de fournir une première évaluation, essentiellement descriptive, de l'ampleur de la mobilité des revenus en Belgique sur base des trois premières vagues d'enquête du Panel Study on Belgian Households. Nous nous efforçons de caractériser et de quantifier cette mobilité entre 1992 et 1994 et de comparer chaque fois que possible les résultats belges avec la performance d'autres pays.

Abstract:
This paper attempts to provide an answer as to why the level of average per capita consumer expenditure, the asset possession or, more prosaically, the apparent level of living in some Indian states are comparatively higher than in states which have yet a higher level of income as measured by the per capita net State Domestic Product. The robustness of a PCNSDP ranking of the sixteen major Indian states is tested against some adjustments to there statistics in order to reglect the average real income of the populations in a better way.
