Online reviews are a powerful means of propagating the reputations of products, services, and even employers. However, existing research suggests that online reviews often suffer from selection bias--people with extreme opinions are more motivated to share them than people with moderate...

During the Great Recession, U.S. unemployment benefits were extended by up to 73 weeks. Theory predicts that extensions increase unemployment by discouraging job search, a partial equilibrium effect. Using data from the large job board CareerBuilder.com, I find that a 10% increase in benefit...

Does the growth of renewable energy benefit US workers, and which workers stand to benefit the most? Until now, evidence on green energy jobs has been limited due to measurement issues. We use data on nearly all jobs posted online in the US, as collected by Burning Glass Technology, and we...

Job differentiation gives employers market power, allowing them to pay workers less than their marginal productivity. We estimate a differentiated jobs model using application data from Careerbuilder.com. We find direct evidence of substantial job differentiation. Without the use of instruments...

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...

Surveys show majority U.S. support for a carbon tax. Yet none has been adopted. Why? We study two failed carbon tax initiatives in Washington State in 2016 and 2018. Using a difference-in-differences approach, we show that Washington's real-world campaigns reduced support by 20 percentage...

Electricity is a general purpose technology and the catalyst for the second industrial revolution. Developing countries are currently making huge investments in electrification, with a view to achieving structural change. What does history say about its impact on the structure of employment? We...

During the COVID-19 pandemic, the Federal Pandemic Unemployment Compensation (FPUC) increased US unemployment benefits by $600 a week. Theory predicts that FPUC will decrease job applications, and could decrease vacancy creation. We estimate the effect of FPUC on job applications and vacancy...

How does employer market power affect workers? We compute the concentration of new hires by occupation and commuting zone in France using linked employer-employee data. Using instrumental variables with worker and firm fixed effects, we find that a 10% increase in labor market concentration...

Wage inequality does not fully capture differences in job quality. Jobs also differ along other key dimensions, including the prevalence of labor rights violations. We construct novel measures of labor violation rates using data from federal agencies. Within local industries over time, a 10%...
