TL;DR: This report adopts an economic perspective on the problem of choosing the optimal portfolio of programs that can be afforded from a limited national healthcare budget and finds that treatment of such political economy perspectives is the least well-developed aspect of the priority setting literature.
Abstract: This report provides a review of the literature on priority setting in healthcare. It adopts an economic perspective on the problem of choosing the optimal portfolio of programs that can be afforded from a limited national healthcare budget. The traditional economic approach, proposes maximizing health gain (however measured) subject to a budget constraint, which implies ranking programs according to their cost-effectiveness ratio. However, our critical review suggests that this traditional approach is subject to three important difficulties: limitations in economic evaluation methodology, incorporating equity principles, and practical constraints. These suggest a need for a fundamental rethink of the role of cost-effectiveness analysis in priority setting. Methodological concerns include identifying whose perspective to adopt, the generalizability of results to multiple settings, the treatment of uncertainty and timing, and the treatment of interactions between programs. Most equity considerations can be captured in two broad headings: equity related to some concept of need and equity related to access to services. In principle equity concerns can be incorporated into an economic approach to priority setting with relative ease. However we find that many contributions to the debate on equity concepts are theoretical and remote from practical implementation issues. The traditional cost-effectiveness approach generally ignores the numerous practical constraints arising from the political, institutional, and environmental context in which priority setting takes place. These include the influence of interest groups, the transaction costs associated with policy changes, and the interactions between the provision and financing of health services. We find that treatment of such political economy perspectives is the least well-developed aspect of the priority setting literature and suggest some rudimentary models that could serve as a starting point for analysis

TL;DR: In this article, a general method for building parametric-functional families of Lorenz curves, generated from an initial Lorenz curve (which satisfies some regularity conditions) is presented, and the results are very robust across data sources.

TL;DR: The authors developed a method to decompose differences across distributions of household income, based on counterfactual distributions that 'lie between' the actually observed distributions, and found that most of Brazil's excess inequality is accounted for by underlying inequalities in the distributions of education and of non-labor income, notably pensions.
Abstract: This paper develops a method to decompose differences across distributions of household income, based on counterfactual distributions that 'lie between' the actually observed distributions. Our approach decomposes differences between any two income distributions (or functionals such as inequality or poverty measures) into shares due to price effects; occupational structure effects; and endowment effects. Comparing the household income distributions of the USA and Brazil in 1999, we find that most of Brazil's excess inequality (of 13 Gini points) is accounted for by underlying inequalities in the distributions of education and of non-labor income, notably pensions (between four and six Gini points each). Steeper returns to education in Brazil also make an important contribution (of two to five points). Differences in occupational structure and in racial and demographic composition are much less important.

TL;DR: In this article, a measure of risk aversion in the small, the risk premium or insurance premium for an arbitrary risk, and a natural concept of decreasing risk aversion are discussed and related to one another.
Abstract: This paper concerns utility functions for money. A measure of risk aversion in the small, the risk premium or insurance premium for an arbitrary risk, and a natural concept of decreasing risk aversion are discussed and related to one another. Risks are also considered as a proportion of total assets.

TL;DR: In this paper, an analysis of the first step of the decision-making process of an individual decision maker among alternative risky ventures is presented, in terms of a single dimension such as money, both for the utility functions and for the probability distributions.
Abstract: Publisher Summary The choice of an individual decision maker among alternative risky ventures may be regarded as a two-step procedure. The decision maker chooses an efficient set among all available portfolios, independently of his tastes or preferences. Then, the decision maker applies individual preferences to this set to choose the desired portfolio. The subject of this chapter is the analysis of the first step. It deals with optimal selection rules that minimize the efficient set by discarding any portfolio that is inefficient in the sense that it is inferior to a member of the efficient set, from point of view of each and every individual, when all individuals' utility functions are assumed to be of a given general class of admissible functions. The analysis presented in the chapter is carried out in terms of a single dimension such as money, both for the utility functions and for the probability distributions. However, the results may easily be extended, with minor changes in the theorems and the proofs, to the multivariate case. The chapter explains a necessary and sufficient condition for efficiency, when no further restrictions are imposed on the utility functions. It presents proofs of the optimal efficiency criterion in the presence of general risk aversion, that is, for concave utility functions.
