Young job seekers commonly misperceive training returns; we test whether these beliefs misalign choices between two widely offered tracks—job-skills and business-skills training for young women in Liberia. We reassign 30 percent of the applicants from an oversubscribed job-skills program to business-skills and compare them to applicants who remain in their preferred track. In the short run, reassigned ...

Large-scale socio-economic panel studies aim to document societal trends and public opinions using representative population samples. Despite the profound impact of artificial intelligence (AI) on public and private life across diverse contexts, these studies have rarely addressed the use and evaluation of AI for individual respondents. Therefore, a standardized assessment instrument is introduced ...

What kind of earnings mobility regime defines our society? Are individuals’ earnings trajectories primarily shaped by their social class position, or do trajectories vary within them? These unresolved questions lie at the heart of debates on social class and labor market rewards.

This paper examines the “right” geographic definition of relevant markets by analyzing how excise tax pass-through varies with local competition in the retail gasoline market of a large metropolitan city. Using a natural experiment from three unanticipated and exogenous fuel tax hikes and detailed station-level price data, we show that average pass-through is invariant to the number of nearby competitors ...

We combine US bills of lading records with ship registry and AIS-based port call data to document new stylized facts on vessel deployment, including switching patterns across ships, country ...
