Notes: The sample includes workers who transitioned to the labor market in 1978 or later. It therefore includes those who took the ASVAB after entering the labor market. This sample is used to estimate average career paths and the effects of layoffs on occupations and wages. Experience is years since the transition began. The task measures refer to the current or most recent job.
