Notes: The main sample includes workers who transitioned to the labor market in 1982 or later (for NLSY79) and 2000 or later (for NLSY97). Experience is years since the transition began. The task measures refer to the current or most recent job. The Table 3 sample is the same but restricts to those with zero to two years of experience.
