December 2019Older Workers Need Not Apply? Ageist Language in Job Ads and Age Discrimination in Hiring
with Ian Burn, Patrick Button, David Neumark: w26552
We study the relationships between ageist stereotypes – as reflected in the language used in job ads – and age discrimination in hiring, exploiting the text of job ads and differences in callbacks to older and younger job applicants from a resume (correspondence study) field experiment (Neumark, Burn, and Button, 2019). Our analysis uses methods from computational linguistics and machine learning to directly identify, in a field-experiment setting, ageist stereotypes that underlie age discrimination in hiring. The methods we develop provide a framework for applied researchers analyzing textual data, highlighting the usefulness of various computer science techniques for empirical economics research. We find evidence that language related to stereotypes of older workers sometimes predicts di...
November 2019Do Minimum Wages Reduce Employment in Developing Countries? A Survey and Exploration of Conflicting Evidence
with David Neumark: w26462
Evidence from studies of the employment effects of minimum wages in developing countries is mixed. One interpretation is that there is simply no clear evidence of disemployment effects in developing countries. Instead, however, we find evidence that the heterogeneity is systematic, with estimated effects more consistently negative in studies with relatively more features for which institutional factors and the competitive model more strongly predict negative effects – studies covering vulnerable workers, in the formal sector, when minimum wage laws are strong, and when minimum wages are binding.
