This paper seeks to compare income distributions from the opportunity advantage viewpoint. That is a measure of how likely it is for a representative individual of one society to receive a higher income than a representative individual of another. Opportunity advantage tries to measure the income opportunities a society offers to an individual, rel...

This paper presents an evaluation protocol that permits evaluating the relative performance of a set of populations in a multidimensional context when outcomes are measured in terms of categorical variables. This problem appears in many different fields, such as Medicine, Social Sciences, or Engineering. The key ingredient for this evaluation is co...
Article
This paper presents an evaluation protocol that transforms a collection of rankings, defined over a set of alternatives, into a complete, transitive, and cardinal assessment. It combines the ideas of Borda and Condorcet by computing the support that each alternative receives on average when confronted with any other. The protocol evaluates those al...

We present in this paper an indicator that approaches the impact of COVID-19 on the community’s health, at this early stage of the pandemic. It consists of the product of the extent (ratio of those affected over the population) and a measure of severity (the intensity of the disease on those affected). We concentrate on the population of those seri...

This paper proposes a new approach to the comparison of income distributions based on the notion of opportunity advantage. This is a measure of how likely is that a representative individual of a society gets a higher income than that of another. Opportunity advantage can be regarded as the evaluation of the income opportunities that a society offe...

Technical Report
Full-text available
The GEP Measurement Framework, in its current version, proposes a method for measuring progress that monitors changes in key variables, taking into account global thresholds that should not be surpassed and utilizing achievable targets selected to help countries to move in the right direction through policy intervention. These components are critic...
Article
This paper focuses on the evaluation of research institutions in terms of size-independent indicators. There are well-known procedures in this context, such as what we call additive rules, which provide an evaluation of the impact of any research unit in a scientific field based upon a partition of the field citations into ordered categories, along...
Article
Full-text available
This paper refers to some social evaluation problems when equity matters. We propose here a way of assessing the equality of opportunity that is applicable to categorical data. It consists of dividing society into groups with similar characteristics and to measure the dispersion of outcomes within those groups, from the distribution of the populati...

There are many different evaluation problems that involve several groups (societies, firms or institutions) whose members can be classified into ordered categories, pursuant to their characteristics or their achievements. This paper addresses these types of problems and provides an evaluation criterion based on the distribution of the agents across...
Article
Full-text available
This paper analyses the evaluation of the relative performance of a set of groups when their outcomes are defined in terms of categorical data and the groups’ members are heterogeneous. This type of problem has been dealt with in Herrero and Villar (2012) for the case of a homogenous population. Here we expand their model controlling for heterogene...

Full-text available
We propose a new Human Development Index that involves a number of changes with respect to the present one, even though it keeps the basic structure of the index (namely, preserving “health”, “education” and “material wellbeing” as the three basic dimensions of human development). The first change refers to the substitution of the arithmetic mean b...

The purpose of this paper is to extend the Rights Egalitarian solution (Herrero, Maschler & Villar, 1999) to the context of non-transferable utility sharing problems. Such an extension is not unique. Depending on the kind of properties we want to preserve we obtain two different generalizations. One is the "proportional solution", that corresponds...

This paper reports an experimental study on three well-known solutions for problems of adjudicating con icting claims: the constrained equal-awards, the proportional, and the constrained equal-losses rules. We first let subjects play three games designed such that the unique equilibrium allocation coincides with the recommendation of one of these t...
Article
We propose a method for calculating the production costs of an intervention in a manner that accounts for differences in productive 'effort.' This method could be used within a cost-effectiveness analysis framework in the evaluation of new medical technologies, pharmaceuticals, treatment programs, or public health interventions. We apply it to show...

We consider allocation problems with indivisible goods when agents' preferences are single-peaked. We propose natural rules (called up methods) to solve such a class of problems. We analyzed the properties those methods satisfy and we provide a characterization of them. We also prove that these methods can be interpreted as extensions to the indivi...

Article
Measures of disability and health-related quality of life are becoming essential parameters in the evaluation of treatment and prevention strategies for reducing the burden of injury. When computing the effectiveness of such measures in health terms, it is frequent to consider pre-injury status as perfect health, as well as the injury status as a c...

This paper provides an axiomatic foundation of a multiplicative human development index, as an alternative to the standard additive one. There are three key advantages that derive from our multiplicative formulation: One, that it is a theoretically well founded measure. Two, that it does no impose the restriction of a constant rate of substitution...
Article
We study claims problems in which a certain amount of indivisible units (of an homogeneous good) has to be distributed among a group of agents, when this amount is not enough to fully satisfy agents' demands. We are interested in finding solutions satisfying robustness and fairness properties. To do that, we define the M-down methods, which are the...

We consider allocation problems with indivisible goods when agents’ preferences are single-peaked. Two natural procedures (up methods and temporary satisfaction methods) are proposed to solve these problems. They are constructed by using priority methods on the cartesian product of agents and integer numbers, interpreted either as peaks or opposite...

Chapter
Quality-adjusted life years (QALYs) are the most frequently used outcome measure in cost utility analysis. In cost utility analysis the benefits of health care programs are not expressed in monetary terms but rather in utility terms. They provide a straightforward procedure to combine quantity of life and quality of life into one single index measu...

This paper reports the results of an experiment in which probabilistic insurance, as proposed by Kahneman and Tversky (1979), is compared both with full insurance and no insurance. The experimental results conform to the intuitive prediction that risk-averse agents who are indifferent between full insurance and no insurance, will prefer full insura...

We show that, under some plausible assumptions, the gain in QALYs a screening program offers is a positive linear transformation of the program's sensitivity level. This result simplifies considerably the cost-utility analysis of mutually exclusive screening programs.

Full-text available
There exist congenital diseases that reduce newborns’ potential opportunities. This reduction is sometimes alleviated if the congenital disease is detected early by a newborn screening program. We propose a new outcome measurement procedure for newborn screening programs, based on the opportunity gains they offer. We show that, under plausible assu...

The economic evaluation of health care programs can be carried out from two different perspectives: the hospital’s narrow perspective and the social perspective, which includes all costs. It is well known that, depending on the perspective, the economic evaluation may lead to discrepant recommendations. In this paper we present an example of this s...
Article
Under expected utility, the individual preferences over lotteries on health profiles can be represented either by a multiplicative utility function, when mutual utility independence is claimed, or, an additive one (known as QALY), when it is claimed additive independence. In this paper, we impose a weaker condition, i.e., utility independence with...

In the management of waiting lists, point systems could be a useful mechanism to establish priorities amongst patients. In this paper we explore the possibility of using Conjoint Analysis (CA) in order to implement a point system based on social preferences. We conducted an experiment for the specific case of cataract extraction. In spite of the pi...

In this work we deal with rationing problems. In particular with claims problems with indivisible goods, that is, problems in which a certain amount of indivisible units (of an homogeneous good), has to be distributed among a group of agents, when this amount is not enough to satisfy agents' demands. We define discrete rules to solve those problems...

In this paper we explore the notion that players are decent, in the sense that their choices are bound by certain unwritten social rules. We apply thisidea to two cases: bankruptcy and bargaining in exchange economies. Wecharacterize the results that are generated by such a behavior in the cases ofbankruptcy and in two person bargaining in exchange...

Full-text available
In this paper we provide a new outcome measure for the cost-utility analyses of alternative screening programs of a particular disease. We show that for non-invasive screening programs satisfying plausible assumptions, QALYs can be replaced by a simpler outcome: the sensitivity of the program. In other words, the cost-utility analysis can be made w...

We deal with a cost allocation problem arising from sharing a medical service in the presence of queues. We use a standard queuing theory model in a context with several medical procedures, a certain demand of treatment and a maximum average waiting time guarantee set by the government. We show that sharing the use of an operating theatre to treat...

This paper focuses on bankruptcy problems and duality. By introducing the idea of dual properties, we obtain a new characterization of the Constrained Equal Losses rule by means of well-known properties. “Dual” procedures to solve discrepancies can also be used to support, noncoopera-tively, the Constrained Equal Awards and the Constrained Equal Lo...
Article
In cost-utility analysis it is assumed that health state valuations are directly comparable across individuals. Instead, health state valuations may be relative and related to people's expectations and abilities. Then health state valuations are not fully comparable across people and, consequently, cost utility analysis cannot be applied in full. T...

We face the problem of allocationg a fixed amount of a perfectly divisible good among a group of agents with single-peaked preferences. We survey the three different cases studied in the literature: the pure distribution case, the redistribution case, and the gerneral case. The so called general case provide with a natural framework to analyze the...

Most axiomatic treatments of bargaining do not give a substantive role to individually irrational points. We show in this paper that it can matter greatly whether axioms and solutions are formulated with respect to the entire feasible set or with respect to only the individually rational portion. In particular, a principle of individual monotonicit...

This paper examines optimal redistribution in a model with high and low-skilled individuals with heterogeneous tastes for labor, that either work or not. With such double heterogeneity, traditional Welfarist criteria including Utilitarianism fail to take the compensation-responsibility trade-off into account. As a response, several other criteria h...

Starting from a finite or countable set of states of health, and assuming the existence of an objective transitive preference relation on that set, we propose a way of performing interpersonal comparisons of states of health. In so doing, we first consider the population divided into types, and consider that two individuals of a different type have...

The axiom translation invariance consists in asserting the invariance of the ranking of two utility streams if one applies the same translation to both. This axiom is significant in the characterization of utilitarian criteria in finite dimension. This characterization is achieved thanks to the "weak weighted utilitarianism theorem".The objective h...
