|July 2019||Minimum Wage Employment Effects and Labor Market Concentration|
with José Azar, Ioana Marinescu, Bledi Taska, Till von Wachter: w26101
Why is the employment effect of the minimum wage frequently found to be close to zero? Theory tells us that when wages are below marginal productivity, as with monopsony, employers are able to increase wages without laying off workers, but systematic evidence directly supporting this explanation is lacking. In this paper, we provide empirical support for the monopsony explanation by studying a key low-wage retail sector and using data on labor market concentration that covers the entirety of the United States with fine spatial variation at the occupation-level. We find that more concentrated labor markets – where wages are more likely to be below marginal productivity – experience significantly more positive employment effects from the minimum wage. While increases in the minimum wage are ...
|May 2018||Livestreaming Pollution: A New Form of Public Disclosure and a Catalyst for Citizen Engagement?|
with Nicholas Muller, Yen-Chia Hsu: w24664
Most environmental policy assumes the form of standards and enforcement. Scarce public budgets motivate the use of disclosure laws. This study explores a new form of pollution disclosure: real-time visual evidence of emissions provided on a free, public website. The paper tests whether the disclosure of visual evidence of emissions affects the nature and frequency of phone calls to the local air quality regulator. First, we test whether the presence of the camera affects the frequency of calls to the local air quality regulator about the facility monitored by the camera. Second, we test the relationship between the camera being active and the number of complaints about facilities other than the plant recorded by the camera. Our empirical results suggest that the camera did not affect the f...
