Getting grey hairs in the labour market. An alternative experiment on age discrimination

This study presents a new field experimental approach for measuring age discrimination in hiring. In addition to the classical approach in which candidates' ages are randomly assigned within pairs of fictitious résumés that are sent to real vacancies, we randomly assign between these pairs the activities undertaken by the older candidates during their additional post-educational years. When applying this design to the case of Belgium, we find that age discrimination depends fundamentally on the older candidates' career patterns. Older age only robustly affects call-back if the older candidate was employed in an out-of-field job during his or her extra post-educational years.
