System-Wide Impacts of Hospital Payment Reforms : Evidence from Central and Eastern Europe and Central Asia
TL;DR: Of the two methods, only PBP appears to have had any beneficial effect on "amenable mortality", but it is found that FFS and PBP both increased national health spending, including private (i.e. out-of-pocket) spending.

TL;DR: In this paper, the authors decompose the redistributive effect of personal income taxes (PITs) of twelve OECD countries into four components: (i) an average rate effect, (ii) a departure from proportionality or progressivity, (iii) a horizontal equity effect and (iv) a reranking effect.
Journal ArticleDOI
Estimating efficiency in the hospital sector: a comparison of three statistical cost frontier models
TL;DR: In this paper, the authors compared three cost frontier models: deterministic cost frontier, a cross-section stochastic cost frontier and a panel-data cost frontier in which inefficiency is assumed to remain constant over time.
BookDOI
Inequalities in health in developing countries - swimming against the tide?
TL;DR: The author identifies four approaches that can shed light on the impacts of anti-inequality policies on health inequalities: cross-country comparative studies, country-based before-and-after studies with controls, benefit-incidence analysis, and decomposition analysis.
Journal ArticleDOI
The concentration index of a binary outcome revisited.
TL;DR: It is argued that while the binary variable has some unusual properties, it shares many of the properties of the ratio-scale variable and hence lends itself to both relative and absolute inequality analyses, albeit with some qualifications.
