Societies prohibit many transactions considered morally repugnant, although potentially efficiency-enhancing. We conducted an online choice experiment to characterize preferences for the morality and efficiency of payments to kidney donors. Preferences were heterogeneous, ranging from...

Early studies often found that offering economic incentives for undertaking prosocial and intrinsically motivated activities can crowd out motivation to perform these activities. More recent work highlights nuanced and important features related to whether crowding out (or substitution) is...

This paper models the optimal provision of incentives to corporate scientists, within an environment where effort is multidimensional, firms compete on the product market, knowledge spills over across companies, and scientists have both monetary and non-monetary motivations. The simultaneous...

We study the interplay between scientific progress and culture through text analysis on a corpus of about eight million books, with the use of techniques and algorithms from machine learning. We focus on a specific scientific breakthrough, the theory of evolution through natural selection by...

The growing demand for plasma, especially for the manufacture of therapeutic products, creates an urgent need for a careful discussion on the relative merits of different procurement and allocation systems in a way that addresses the increasing demand while abiding by the prevailing moral values...

The growing demand for plasma, especially for the manufacture of therapeutic products, prompts discussions on the merits of different procurement systems. We conducted a randomized survey experiment with a representative sample of 826 Canadian residents to assess attitudes toward legalizing...

Using longitudinal data on the entire population of blood donors in an Italian town, we examine how donors respond to an award scheme which rewards them with medals when they reach certain donation quotas. Our results indicate that donors significantly increase the frequency of their donations...

This paper analyzes the effects of a legislative provision that grants a one-day paid leave of absence to blood donors who are employees in Italy. The analysis is based on a unique dataset with the complete donation histories of the blood donors in an Italian town. The cross-sectional variation...

We examine how economic incentives affect pro-social behavior through the analysis of a unique dataset with information on more than 14,000 American Red Cross blood drives. Our findings are consistent with blood donors responding to incentives in a standard way; offering donors economic...
