We establish the asymptotic sampling distribution of general functions of quantile-based estimators computed from samples that are not necessarily independent. The results provide the statistical framework within which to assess the progressivity of taxes and benefits, their horizontal inequity, and the change in the inequality of income which they cause. By the same token, these findings chara...

The effect of taxes and benefits on the poor is usually measured using standard poverty and inequality indicators, stochastic dominance tests, and measures of progressivity and horizontal inequity. However, these measures can fail to capture an important aspect: that some of the poor are made poorer (or some of the non-poor made poor) by the tax-benefit system. We call this impoverishment and f...

This paper uses two methods to compare the impact of health care payments under insurance and user fees. Concentration indices for insured and uninsured groups are computed following the indirect standardisation method to evaluate horizontal inequity in utilisation of basic health care services. The minimum standard approach analyses the extent to which out-of-pocket health spending contributed...

Wealth-related inequity in the use of maternal healthcare services continues to be a substantial problem in most low- and middle-income countries. One strategic approach to increase the use of appropriate maternal healthcare services is to encourage the expansion of the role of the private sector. However, critics of such an approach argue that increasing the role of the private sector will lea...

This paper explores whether the principles of horizontal and vertical equity in healthcare are met by the Spanish national health system in the case of the Roma and general populations. The 2011/2012 Spanish National Health Survey (n = 21,650) and the 2014 National Health Survey of the Spanish Roma Population (n = 1167) were analyzed. Use of healthcare services was measured in terms of visits t...

BACKGROUND Inequity in use of physician services has been detected even within health care systems with universal coverage of the population through public insurance schemes. In this study we analyse and compare inequity in use of physician visits (GP and specialists) in Norway based on data from the Surveys of Living Conditions for the years 2000, 2002 and 2005. A patient list system was intro...

INTRODUCTION This study assesses trends in horizontal equity in the utilization of healthcare services from 1998 to 2008--a period of major economic and social change in Brazil. METHODS Data are from nationally representative surveys repeated in 1998, 2003, and 2008. We apply established methods for assessing horizontal inequity in healthcare access (the principle that people with the same he...

BACKGROUND One strategic approach available to policy makers to improve the availability of reproductive and child health care supplies and services as well as the sustainability of programs is to expand the role of the private sector in providing these services. However, critics of this approach argue that increased reliance on the private sector will not serve the needs of the poor, and could...

OBJECTIVE This study sought to examine the sources of inequity in health examination service utilization by women from underdeveloped areas in western China. METHODS Based on data from the 5th National Health Service Survey in Shaanxi province, women's utilization of health examination services was examined according to gynecological, cervical smear, and breast examination rates. The equity o...
