“…In terms of laborers, workers who are subject to an occupational license often benefit from wage premiums within many industries; however, some studies have found that these licenses have also reduced aggregate economic and geographic mobility (Timmons and Thornton, 2008; Perloff, 1980; Guis, 2016; Kleiner and Park, 2010; Kleiner and Krueger, 2010, 2013; Meehan et al , 2019). In areas and industries with these wage premiums, there is also evidence of reduction in labor supply entry (Thornton and Weintraub, 1979; Hall and Pokharel, 2016; Zapletal, 2018). These wage premiums are thought to represent the additional cost of education and training, incentivize public health and safety and increase overall quality of goods and services (Akerlof, 1970; Shapiro, 1986).…”
