The assumption of positive time preference is seldom challenged in analyses of intertemporal choices, despite considerable evidence of zero and negative discount rates. In this study, the majority of respondents have positive discount rates, but a substantial number have negative or zero...

This paper models the costs of collecting whole blood in the north of Scotland in order to investigate strategies whereby the annual collection target can be met at lower cost. Data on the costs of the individual sessions held in 1993-1995 are analyzed using multilevel analysis. A new technique,...

This paper compares three models of intertemporal choice concerning saving future lives: the constant discounting model, the proportional discounting model and the hyperbolic discounting model. The three models were investigated using data collected from the general public. Since these data have...

It has been suggested that individuals employ simple decision heuristics when answering stated preference questions. Evidence from discrete choice experiments of individuals failing to trade may indicate that they employ simple decision making heuristics. However, individuals might not trade...

Multilevel models (MLMs) have been recommended for estimating incremental net benefits (INBs) in multicentre cost-effectiveness analysis (CEA). However, these models have assumed that the INBs are exchangeable and that there is a common variance across all centres. This paper examines the...

Purpose: To study the willingness-to-pay (WTP) for a proposed community-based health insurance (CBI) scheme in order to provide information about the relationship between the premium that is required to cover the costs of the scheme and expected insurance enrolment levels. In addition, factors...
