This paper measures excess labor supply in equilibrium. We examine hiring shocks--which employ 24% of the labor force in external month-long jobs--in Indian local labor markets. In peak months, wages increase instantaneously and local aggregate employment declines. In lean months, consistent...

We evaluate a large-scale set of interventions to increase demand for immunization in Haryana, India. The policies under consideration include the two most frequently discussed tools--reminders and incentives--as well as an intervention inspired by the networks literature. We cross-randomize...

Social norms have the potential to alter the functioning of economic markets. We test whether norms shape the aggregate labor supply curve by leading decentralized individuals to maintain wage floors in their local labor markets. We partner with existing employers who create new jobs for workers...

We test whether increasing cash-on-hand raises the productivity of poor workers. Our motivation is psychological. Concerns about money can create mental burdens such as worry, stress, or sadness. These in turn could interfere with the ability to work effectively. We empirically test for this...

Formal financial institutions can have far-reaching and long-lasting impacts on informal lending and information networks. We first study 75 villages in Karnataka, 43 of which were exposed to microfinance after we first collected detailed network data. Networks shrink more in exposed villages....

This paper uses household survey data form several developing countries to investigate whether the poor (defined as those living under $1 or $2 dollars a day at PPP) and the non poor have different mortality rates in old age. We construct a proxy measure of longevity, which is the probability...

The idea that worker utility is affected by co-worker wages has potentially broad labor market implications. In a month-long experiment with Indian manufacturing workers, we randomize whether co-workers within production units receive the same flat daily wage or different wages (according to...

This paper tests for downward nominal wage rigidity by examining transitory shifts in labor demand, generated by rainfall shocks, in 600 Indian districts from 1956-2009. Nominal wages rise in response to positive shocks but do not fall during droughts. In addition, transitory positive shocks...

Schooling may build human capital not only by teaching academic skills, but by expanding the capacity for cognition itself. We focus specifically on cognitive endurance: the ability to sustain effortful mental activity over a continuous stretch of time. As motivation, we document that globally...
