“…To obtain information about employees and their dates of employment, we use Denmark's Integrated Database for Labor Market Research (IDAN), an economy‐wide employer‐employee‐matched administrative database. Thus, rather than using survey data, job postings (e.g., Gutiérrez et al., 2020) or employees’ self‐reported LinkedIn profiles (Agrawal et al., 2021; Li et al., 2022), we can count the actual annual number of employees arriving and departing for a significant proportion of Danish limited liability firms across the period of 1998−2016. The data also provide information on salary, position within the firm, tenure, age, gender and education, data that allow us to control for (and condition on) various factors not found in most other settings.…”
