This paper analyzes the impact of the German autobahn net on the economic performance of German regions. To address endogeneity and reverse causation problems, we use historical instrument variables, i.e. a plan of the railroad net in 1890 and a plan of the autobahn net in 1937. We find a...

We study whether commuting barriers constrain women's labor supply in urban Pakistan. We randomize offers of gender-segregated or mixed-gender commuting services at varying prices. Women-only transport more than doubles job application rates, while mixed-gender transport has minimal effects on...

This paper explores the economic effects of imperfect meritocracy in recruitment and career advancement. We compare two career promotion mechanisms: a fully meritocratic system and a "noisy" one, that allows less productive workers to advance. Our model shows that imperfect meritocracy in...

The UK Universal Credit (UC) welfare reform simplified the benefits system whilst strongly incentivising a return to sustainable employment. Exploiting a staggered roll-out, we estimate the differential effect of entering unemployment under UC versus the former system on mental health. Groups...

In 2021, the Biden Administration issued mandates requiring COVID-19 vaccinations for U.S. federal employees and contractors and for some healthcare and private sector workers. Although these mandates have been subject to legal challenges and some have been halted or delayed, rigorous appraisal...

This paper examines the economic foundations of three criteria used for evaluating the costs and benefits of social programs. Some criteria do not consider the scale of programs or address the costs associated with programs that expand or contract the total government budget. A recent addition...

In low-income communities in both rich and poor countries, redistributive transfers within kin and social networks are frequent. Such arrangements may distort labor supply—acting as a "social tax" that dampens the incentive to work. We document that across countries, from Cote d'Ivoire to the...
