The purpose of this paper is to combine multidimensional welfare analysis and entropy metrics to derive not only the best relative weights but also substitution degree among different attributes to construct multidimensional indices of well-being with Chinese Household Income Project Survey 2002 data.

The authors follow Maasoumi’s two-step measures of multivariate inequality to calculate the inequality for three social groups in China, urban residents, migrants, and rural residents. The two-step approach provides an aggregation formula which is numerically identified in this paper based on a metric entropy distance measure between the distribution of the aggregate well-being functions, on the one hand, and the distribution of the self-reported “happiness” indicator. The authors compare the differences in relative weights and substitution degree for the three groups, and link them to some institutional factors.

The authors find that incorporating substitution among attributes, and taking into consideration group heterogeneity are very important in multidimensional analysis of well-being.

Building on recent advances in inverse probability weighted identification and estimation of counterfactual distributions, the authors examine the history of wage earnings for women and their potential wage distributions in the United States. These potentials are two counterfactuals, what if women received men’s market “rewards” for their own “skills,” and what if they received the women’s rewards but for men’s characteristics? Using the Current Population Survey data from 1976 to 2013, the authors analyze the entire counterfactual distributions to separate the “structure” and human capital “composition” effect. In contrast to Maasoumi and Wang (2019), the reference outcome in these decompositions is women’s observed earnings distribution, and inverse probability methods are employed, rather than the conditional quantile approaches. The authors provide decision theoretic measures of the distance between two distributions, to complement assessments based on mean, median, or particular quantiles. We assess uniform rankings of alternate distributions by tests of stochastic dominance in order to identify evaluations robust to subjective measures. Traditional moment-based measures severely underestimate the declining trend of the structure effect. Nevertheless, dominance rankings suggest that the structure (“discrimination”?) effect is bigger than human capital characteristics.

We examine the cardinal gap between wage distributions of the incumbents and newly hired workers based on entropic distances which are well-defined welfare theoretic measures. Decomposition of several effects is achieved by identifying several counterfactual distributions of different groups. These go beyond the usual Oaxaca–Blinder decompositions at the (linear) conditional means. Much like quantiles, these entropic distances are well-defined inferential objects and functions whose statistical properties have recently been developed. Going beyond these strong rankings and distances, we consider weak uniform ranking of these wage outcomes based on statistical tests for stochastic dominance. The empirical analysis is focused on employees with at least 35 hours of work in the 1996–2012 monthly Current Population Survey (CPS). Among others, we find incumbent workers enjoy a better distribution of wages, but the attribution of the gap to wage inequality and human capital characteristics varies between quantiles. For instance, highly paid new workers are mainly due to human capital components, and in some years, even better wage structure.

We examine the potential effect of naturalization on the U.S. immigrants’ earnings. We find the earning gap between naturalized citizens and noncitizens is positive over many years, with a tent shape across the wage distribution. We focus on a normalized metric entropy measure of the gap between distributions, and compare with conventional measures at the mean, median, and other quantiles. In addition, naturalized citizen earnings (at least) second-order stochastically dominate noncitizen earnings in many of the recent years. We construct two counterfactual distributions to further examine the potential sources of the earning gap, the “wage structure” effect and the “composition” effect. Both of these sources contribute to the gap, but the composition effect, while diminishing somewhat after 2005, accounts for about 3/4 of the gap. The unconditional quantile regression (based on the Recentered Influence Function), and conditional quantile regressions confirm that naturalized citizens have generally higher wages, although the gap varies for different income groups, and has a tent shape in many years.

The purpose of this paper is to examine the correlation between childhood poverty and its influence on adulthood wage distribution, where childhood poverty refers to the experience of poverty or poor family background during one’s childhood.

With data from the Korean Labor and Income Panel Study, a quantile regression technique and a decomposition method are conducted to identify and decompose the wage gap between low (poor) and middle class income groups along the whole current wage distribution, based on a simulated counterfactual distribution.

The results show that those who had been less fortunate during their childhood were also less likely to have the opportunity to gain labor market favored characteristics, such as a higher level of education, and even earn lower returns to their labor market characteristics in the current labor market. This leads to a discount of about 15 percentage points in the wage, on average, in total for those with underprivileged backgrounds during childhood compared to those with a middle class background. This disadvantage is observed heterogeneously, with a greater effect at the lower quantiles compared to the higher quantiles of the current wage distribution.

This research contributes to the literature by providing a partial understanding of poverty in Korea along with possible causes, including poor family background or childhood poverty, with which the implication of an intergenerational effect is considered.

The purpose of this paper is to study the efficiency and financial situation of Spanish airlines by conducting a comparative analysis of those operating in hubs and those that employ the point-to-point system.

Data envelopment analysis and accounting rates are implemented to do so.

The results show that hubs do not result in the companies that use them being efficient. Instead, it is the charter, low-cost and private flight operators that best manage their resources.

The study makes a novel contribution to the literature, as there has been no research on Spanish airlines that compares the two types of operators (hubs and point to point).

The purpose of this paper is to aim at taking a closer look at the decline in the inequality of the distribution of four health variables, infant and child mortality, child stunting and underweight, that took place in various Southeast Asian countries during the past 25 years. More specifically its goal is to check the extent to which this decline in health inequality, as well as the overall reduction in infant and child mortality, in child stunting and underweight, affected the poorest wealth quintile of the population of these countries.

In the first part of the paper the author presents a systematic comparison of the values taken by various consistent measures of the inequality of health attainments and shortfalls for several countries in Southeast Asia and for four health indicators: infant mortality, child mortality, child stunting and underweight. The second part of the paper uses the concept of Shapley decomposition to determine the respective impacts of the decrease in the average value of these health variables and in the inequality of their distribution on the reduction observed for each of these variables in the lowest wealth quintile.

During the period examined there was an important decline infant and child mortality as well as in child stunting and underweight in all countries of Southeast Asia for which data were available. As far as the poorest wealth quintile is concerned this decline was mostly the consequence of the overall decline in these health variables rather than to the reduction of the inequality of their distribution.

Data were available for only four health variables and for many countries data were available for only one period.

A decline in health inequality should be considered as an important aspect of poverty reduction.

Development should not be limited to its economic components. A broader view of development is indispensable.

This study is probably one of the first ones to provide the reader with data on the reduction in health inequality in Southeast Asia as well as on the impact of this decline on the poorest wealth quintile.

The purpose of this paper is to examine asymmetric co-integration effects between nutrition and economic growth for annual South African data from the period 1961-2013.

The authors deviate from the conventional assumption of linear co-integration and pragmatically incorporate asymmetric effects in the framework through a fusion of the momentum threshold autoregressive and threshold error correction (MTAR-TEC) model approaches, which essentially combines the adjustment asymmetry model of Enders and Silkos (2001); with causality analysis as introduced by Granger (1969); all encompassed by/within the threshold autoregressive (TAR) framework, a la Hansen (2000).

The findings obtained from the study uncover a number of interesting phenomena for the South Africa economy. First, in coherence with previous studies conducted for developing economies, the authors establish a positive relationship between nutrition and economic growth with an estimated income elasticity of nutritional intake of 0.15. Second, the authors find bi-direction causality between nutrition and economic growth with a stronger causal effect running from nutrition to economic growth. Lastly, the authors find that in the face of equilibrium shocks to the variables, policymakers are slow to responding to deviations of the variables from their co-integrated long run steady state equilibrium.

In the study, the authors make a novel contribution to the literature by exploring asymmetric modelling in the correlation between nutrition intake and economic growth for the exclusive case of South Africa.

The purpose of this paper is to investigate the impact of liberalisations policies on income inequality in African countries. Examining whether the liberalisations policies have affected the income distribution of everyone equally or they only assist those who are already relatively well off; leaving the poor behind. The authors also examine how they affect income distribution in the various countries within the continent, and their effect on short and long runs?

First, The authors used the before and after comparison, to examine the response of the level of income inequality and the volatility of income inequality from the time that financial or trade liberalisations took place in each country. Next, the authors used the panel data techniques model for a sample of 26 African countries spanning the period 1996-2010 to investigate the effect of liberalisation policies on income distribution.

The authors find that financial liberalisation has a levitated income-redistributive effect with the magnitude of the de jure measure (KAOPEN) higher than that of the de facto measure (FDI); that exports, trade and “freedom to trade” have an equality incidence on income distribution; and that institutional and/or political liberalisation has a negative impact and; economic freedom has a negative income-redistributive effect, possibly because of the weight of its legal component.

In general, this study provides a variegated picture, findings tend to suggest that overall the reforms have increased income inequality in African countries. It would be risky to prescribe a general policy because of the diversity of the country. However, African countries’ better performance can be attributed to a combination of policies. For example avoiding the Marco price mixture of real exchange rate appreciation and high domestic interest rates; having capital controls and prudential financial regulations which would enable them to contain the negative consequence of capital flows; putting a system in place to direct export between African countries and encouraging sub regional integration agreement. The government should put in place countervailing social policies in order to withstand social coherence and smooth the adverse transition of liberalisation policies.

Three main elements of originality clearly standout: first, the estimation approach used in the paper considers both short- and long-run effects of in empirical strategy; second, an exhaustive plethora of liberalisation policies (trade, financial, political and institutional are considered); and third, recent data are used to appraise second generation reforms for more updated policy implications.
