How do income and education affect health inequality: evidence from four developing countries

Using household survey data from four countries ? Albania, Nepal, Tajikistan and Tanzania ? this article calculates income-related inequality in health care utilization. We measure health disparity separately for generally and chronically ill individuals by constructing two models: one for the probability of a visit to a physician and another for the number of visits. Following model-based measurements, we decompose inequality into two major parts: one accounted for by identity-related factors and another by socioeconomic and other factors such as education, geography and distance to a clinic. We propose a new method to quantify the effect of changes in income and education on health disparity. One of our important findings suggests that health disparity is pro-rich in all our sample countries. The pro-rich disparity is prevalent among generally ill as well as chronically ill patients, in both visit probability and visit frequency models. Health inequality seems primarily driven by income differences followed by nonidentity factors. Further, the principle of equal treatment for equal need is not fulfilled in any of our countries. Among policy implications, increasing average income and education in a way that also reduces disparity in income and education, respectively, will substantially shrink inequality in health care utilization.     

Labour mobility and wage inequality in the presence of endogenous foreign investment

This paper examines the impact of labour mobility and increased competition on skilled–unskilled wage inequality and foreign investment. Unlike the existing literature this paper considers a model where foreign investment is endogenously determined. The paper shows that in the shortrun, inflow of either skilled or unskilled labour has no effect on wage inequality but increased competition increases wage inequality. Inflow of either type of labour increases foreign investment but the impact of increased competition on foreign investment cannot be unambiguously determined. Inflow of skilled labour increases wage inequality in the longrun and its effect on foreign investment is positive. Increased competition in the longrun increases wage inequality, foreign investment and welfare.     

How to promote R&D-based growth? Public education expenditure on scientists and engineers versus R&D subsidies

This paper compares the positive and normative implications of two alternative measures to promote R&D-based growth: R&D subsidies to firms and publicly provided education targeted to the development of science and engineering (S&E) skills. The model accounts for the specificity of S&E skills, where individuals with heterogeneous ability choose their type of education. Although intertemporal knowledge spillovers are the only R&D externality, the analysis suggests that R&D subsidies may be detrimental to both productivity growth and welfare. Moreover, they raise earnings inequality. In contrast to R&D subsidies, publicly provided education targeted to S&E skills are found to be unambiguously growth-promoting and neutral with respect to the earnings distribution.     

EARNINGS INEQUALITY, LABOUR SUPPLY AND SCHOOLING IN HUSBAND–WIFE FAMILIES

This paper describes the association between market work and earnings inequality across families over the life cycle and over calendar time with special attention to the different experiences of college‐educated and high‐school‐educated people. A concise and effective accounting framework is developed that allows for an assessment of the effect of the growing market employment of married women on family earnings inequality. Applying this framework to pseudo‐panel data from successive Current Population Surveys indicates that the increase in wives' employment has diminished the growth in family earnings inequality especially for well‐educated couples. Inferences about the level and change in earnings inequality depend on the degree of labor market attachment of the people studied especially in the case of wives.
