Twins-based estimates of the return to schooling feature prominently in the labor economics literature. The validity of such estimates hinges critically on the assumption that within-pair variation in schooling is explained by factors which are unrelated to wage earning ability. This paper...

Ex post mitigation of hypothetical bias using follow up certainty questions typically takes one of two forms: (1) two options, "definitely sure" and "probably sure", or (2) a 10-point scale with 10 very certain. While both have been successful in eliminating hypothetical bias from estimates of...

In this study we report an attempt to measure the value adult Swedes impute to an increased survival probability at high ages. A rating scale between the worst possible quality of life (=3D1) and the best possible quality of life (=3D10) is used to indicate the quality of life a person expects...

This study reports an attempt to measure the value of an increased survival probability at high ages. It turns out that the average willingness to pay for a programme which would increase the expected length of life by one year, conditional on having survived to the age of 75 years, is lower...

In this study we report an attempt to measure the WTP of car owners for a reduction of the probability of being killed in a traffic accident. One group of respondents is offered a safety device to be installed in their car, while another group is offered a public safety program (improved road...

In this study, one group of respondents is offered to purchase a safety device to be installed in their car, while another group is offered a public safety program (improved road quality) which results in the same size risk reduction. In terms of the value of a statistical life, our results are...

We analyze the computational reproducibility of more than 1,000 empirical answers to six research questions in finance provided by 168 international research teams. Surprisingly, neither researcher seniority, nor the quality of the research paper seem related to the level of reproducibility....
