Descriptive analysis of the vacancy database
Given the high cost of collecting labour demand for skills information through surveys, the composition and dynamics of Colombian labour demand are relatively unknown. However, information regarding unmet labour demand can be collected from job portals with the implementation of relatively novel data mining techniques. This paper provides a descriptive analysis to start evaluating the […]
Information problem in labour market and big data: colombian case
This working paper discusses the concepts and theoretical framework to analyse the labour market, based on the information found on online job portals. Based on a model with imperfect information (which seems more appropriate to describe Colombian labour market outcomes), the first section explains how skill mismatches can arise and their consequences for informality and […]

Also, it elaborates on, for the first time in Colombia, a set of macro indicators within the vacancy database’s labour […]
