First and third column show the coefficient of variation with respect to average establishments wages of every cohort in the year of birth, both for the full sample of entering establishments (first column) and for those entering establishments that survived at least 10 years (third column). Second and fourth column show the difference between the coefficient of variation after 10 years and the coefficient of variation in the birth year, again for both samples
