Notes:
Panel (a) describes the sample selection strategy. We initially collected 249 answers to the questionnaire we sent. After discarding the answers with multiple missing values and adopting filters in terms of job and number of years of experience, we netted the sample of 76 organizations with a total of 228 observations in the period analyzed (2017–2019). Panel (b) discloses the industries of the entities belonging to the final sample. Panel (b) also reports the number of firms and the firm-year observations (FYO), for each industry, the percentage compared to the total number of FYO, and the cumulative frequency
