“…Lastly, this paper is also relevant to a recent and rapidly expanding literature that utilizes highly detailed data from online job vacancies to investigate various labor market issues. These include: (i) variations in job tasks and skill requirements across geographical locations, as well as between and within narrowly defined occupations (Atalay et al, 2023;Deming and Kahn, 2018); (ii) changes in labor and skill demand in response to minimum wage increases (Clemens et al, 2021), computerization (Dillender and Forsythe, 2022), business cycle fluctuations (Modestino et al, 2016;, and severe shocks such as the Great Recession (Hershbein and Kahn, 2018) and the Covid-19 pandemic (Chetty et al, 2020;Forsythe et al, 2020;; (iii) the role of job postings' semantic content for the process of search and matching (Marinescu and Wolthoff, 2020), also in relation to gender and age discrimination in recruitment (Card et al, 2023;Helleseter et al, 2020;Kuhn et al, 2020;Kuhn and Shen, 2013;; (iv) labor market concentration and its mediating role on the employment effects of minimum wage increases (Azar et al, 2020;; and (v) trends in the demand for AI skills, and the interplay between AI adoption and various firm and labor market outcomes (Acemoglu et al, 2022;Alekseeva et al, 2021;Babina et al, 2022a;2022b). Our contribution to this body of literature lies in providing evidence on the effects of a policy reform concerning labor contracts on the demand for labor and skills.…”
