The concept of economic development has broadened to include environmental quality and population health. Interactions between income and pollution, income and health, and pollution and health have been studied separately by researchers from various disciplines. This study attempts to unify several different research strands and analyze simultaneous interactions between population health, measured by the infant mortality rate, pollution, and income in one endogenous system. Socioeconomic, racial, and rural urban disparities in infant mortality, pollution, and income are analyzed. The simultaneous equation system, estimated using the two-stage least squares method, tests whether pollution effects on infant mortality are outweighed by income effects. The study finds that income is a stronger determinant of infant mortality than pollution. Evidence for the environmental Kuznets curve is ambiguous. Disparities in infant mortality, pollution, and income are correlated with counties rural-urban status, income inequality, and ethnic diversity. Regional patterns identify wide geographical differences in levels of pollution, income, and infant mortality. The Southeast region stands out as a region with the highest infant mortality rate, relatively high levels of air pollution and chemical releases, and low per capita incomes.

This paper investigates the nexus between regional income levels and inequality. We present a novel small-scale inequality database for Austrian municipalities to address this question. Our dataset combines individual tax data of Austrian wage tax payer on regionally disaggregated scale with census and geographical information. This setting allows us to investigate regional spillover effects of average income and various measures of income inequality. Using this data set we find distinct regional clusters of both high average wages and high earnings inequality in Austria. Furthermore we use spatial econometric regressions to quantify the effects between income levels and a number of inequality measures such as the Gini and 90/10 quantile ratios.

La ressource en eau à Jakarta est abondante,du fait que la pluviométrie annuelle moyenne à Jakarta est de 2500 mm/an et que la ville est traversée par 13 cours d’eau d’importance. Cependant, elle ne peut pas répondre aux besoins de ses habitants en matière d’approvisionnement en eau. De plus, l’accès à l’eau propre est inégal en fonction des critères socio-spatiaux de la communauté jakartanaise. Par ailleurs, la société indonésienne, dans son ensemble et la société jakartanaise en particulier, ont tendance à penser que la ressource en eauest illimitée. Cela conduit à une utilisation excessive de la ressource en eau qui aggrave le problème d’approvisionnement en eau. En se basant sur les enjeux ci-dessus, cette étude cherche premièrement à mettre en évidence les causes du paradoxe de l’eau à Jakarta en tenant compte de la trajectoire historique de l’approvisionnement en eau à Jakarta. Deuxièmement, des enquêtes de terrain auprès de la communauté jakartanaise en fonction des catégories socio-spatiales différentes ont été effectuées pour connaître la compréhension de l’inégalité de l’approvisionnement en eau qu’ont les citadins qui vivent ce phénomène au jour le jour, et en quoi cela affecte leurs perceptions etleurscomportements sur l’eau. Enfin, comme Jakarta est peuplée de 9,7 millions de personnes, les économies d’eau réalisables paraissent importantes. Une approche empruntée au domaine du marketing, «le marketing social», me semble prometteuse pour convaincre les populations d’économiser l’eau. Une étude de cas du programme « Gerakan Molto Ultra Sekali Bilas/ Mouvement d’un seul rinçage», effectué par Unilever, sera analysée pour valoriser et justifier le potentiel du marketing social. / The water resources in Jakarta are abundant because the average rainfall in Jakarta is 2500 mm/year and this city is crossed by 13 important rivers. However, Jakarta cannot meet the needs of its inhabitants when it comes to an appropriate “drinkable” water supply. The access to the appropriate“drinkable” water is unequal according to various socio-spatial criteria pertaining to the Jakartan community. Moreover, the Indonesian society in general, and Jakartans in particular, tend to think that water resources are unlimited. It leads to an excessive use of water resources which deteriorates the water supply problem in Jakarta. Based on the issues above, this study tries in the first place to highlight the causes of the water paradox in Jakarta, taking into account an historical trajectory of the way the water supplying system evolved in Jakarta. Secondly, field surveys within the Jakartan community, according to the different socio-spatial categories, were conducted to see how the inhabitants understand the disparity of the water supply, as they face this phenomenon day to day. It can affect their perceptions and behaviors concerning water. Finally, since the Province of Jakarta is populated with 9.7 million people, water savings seem important. The approach borrowed from the marketing domain, “social marketing” appears to hold potential to convince and persuade the community to preserve water. A case study of Unilever’s program, “Gerakan Molto Ultra Sekali Bilas”, will be analyzed in order to justify the potential of social marketing.
