On-demand labor platforms make up a large part of the “gig economy.” We quantify the extent of monopsony power in one of the largest on-demand labor platforms, Amazon Mechanical Turk (MTurk), by measuring the elasticity of labor supply facing the requester (employer) using both observational...

Does foreign military assistance strengthen or further weaken fragile states facing internal conflict? We address this question by estimating how U.S. military aid affects violence and electoral participation in Colombia. We exploit the allocation of U.S. military aid to Colombian military...

We show that administrative hourly wage data exhibits considerable bunching at round numbers that cannot be explained by rounding of survey respondents. We consider two explanations--worker left-digit bias and employer optimization frictions. We experimentally rule out left-bunching by...

We provide new estimates of the separations elasticity, a proximate determinant of the labor supply facing a firm with respect to hourly wage, using matched Oregon employer-employee data. Existing estimates using individual wage variation may be biased by mismeasured wages and use of wage...
