Measuring Skill level integrating Administratrive Dataset and National Collective Agreement Archive

Given the group job classification and collective agreement identification code, we extracted from the national bargaining archive the skill level definition and we created a skill grades classification for the workers. We added this information to Workers History Italian Panel -Whip-, and we created a new variable which allow us to identify whether a worker is skilled or unskilled. The new skill level variable increase the possibility for a better comprehension of labour market issues as well as for new studies in the field of job risk evaluation. The sections are organized as follow: 1. creation of skill level classification from national collective agreements archive; 2. short explanation of Whip archives; 3. adding informations to Whip archives; 4. checking the consistency and coverage of the skill level variable in Whip; 5. a first interpretation of the resulting skill distribution.
