This paper considers a model in which bidders in an auction are faced with uncertainty as to their final valuation of the auctioned object. This uncertainty is resolved after the auction has taken place. It is argued that the inclusion of a cooling-off right raises the expected revenue to the...

This study applies conjoint analysis (CA) to estimate the marginal willingness-to-pay (MWTP) of elderly individuals for a reduction of the risk of fracture of the femur. The good in question are hypothetical hip protectors which lower the risk of a fracture by different amounts. Other attributes...

This paper examines experimental evidence relating to herd behaviour in situations when subjects can learn from each other, and can delay their decision. Subject acted rationally, gaining from observational learning, despite penalties for delay. Cascades were ubiquitous and reverse-cascades...

This paper explores the effects of group identity and gender in a public goods experiment. We compare the behavior of participants who can be expected to have a pre-existing sense of group identity to that of randomly selected participants, and to that of participants who have undertaken...

Sample attrition is a potential source of selection bias in experimental as well as non-experimental programme evaluation. For labour market outcomes such as employment status and earnings, missing data problems caused by attrition can be circumvented by collection of follow-up data from...

Goods are said to be combinatorial when the value of a bundle of goods is not equal to the sum of the values of the same goods unbundled. Investigations of combinatorial allocation problems should recognize that there are two separate aspects of such problems: an environmental distinction...

Establishing causal relationships in social policy evaluation is important, but difficult due to sample selection. To evaluate the performance of estimators designed to handle sample selection bias we analyse data from a Norwegian rehabilitation project with a randomised experimental design. The...
