We present the results from a natural experiment in which single mothers on welfare were stimulated to find a job. Two policy instruments were introduced: an earnings disregard and job creation. The experiment was performed at the level of municipalities in The Netherlands, a country with...

This study presents an overview of modern field experiments and their usage in economics. Our discussion focuses on three distinct periods of field experimentation that have influenced the economics literature.

This paper presents evidence from a field experiment, which aims to identify the two sources of workers' pro-social motivation that have been considered in the literature: action-oriented altruism and output-oriented altruism. To this end we employ an experimental design that first measures the...

This study designs a natural field experiment linked to a controlled labo- ratory experiment to examine the effectiveness of matching gifts and challenge gifts, two popular strategies used to secure a portion of the $200 billion annually given to charities. We find evidence that challenge gifts...
