This paper tests the internal consistency of time trade-off utilities. We find significant violations of consistency in the direction predicted by loss aversion. The violations disappear for higher gauge durations. We show that loss aversion can also explain that for short gauge durations time...

This paper studies two important reasons why people violate procedure invariance, loss aversion and scale compatibility. The paper extends previous research on loss aversion and scale compatibility by studying loss aversion and scale compatibility simultaneously, by looking at a new decision...

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...

The Person Trade-Off (PTO) is a methodology aimed at measuring the social value of health states. The rest of methodologies would measure individual utility and would be less appropriate for taking resource allocation decisions. However few studies have been conducted to test the validity of the...

Expected utility theory (EUT) has been challenged as a descriptive theory in many contexts. The medical decision analysis context is not an exception. Several researchers have suggested that rank dependent utility theory (RDUT) may accurately describe how people evaluate alternative medical...

In this paper we address the importance of distributive effects in the social valuation of QALY's. We propose a social welfare function that generalises the functions traditionally used in the health economic literature. The novelty is that, depending on the individual health gains, our function...

The general issues of equity and efficiency are placed at the center of the analysis of resource allocation problems in health care. We examine them using axiomatic bargaining theory. We study different solutions that have been proposed and relate them to previous literature on health care...

In cost-effectiveness analysis (CEA) it is usually assumed that a QALY is of equal value to everybody, irrespective of the patient's age. However, it is possible that society assigns different social values to a QALY according to who gets it. In this paper we discuss the possibility of weighting...
