Notes: Data for all series in panels B and D come from CPS outgoing monthly rotation group microdata. Data for panel A comes from all CPS monthly microdata (NBER extracts). The dots in panel C are calculated from Census 5% microdata extract (from IPUMS). For panel A the dotted line is the fraction of 16-17 year olds enrolled in June July and August and the sample is only those who have observations in these three months that can be matched in the CPS; matching was not possible for 1985. For panel D teen jobs are everything in the retail food service and other personal services industries in addition to the following occupations: janitor cashier child care worker farm laborer gardener usher bellhop stock handler construction laborer.

Note: Each line plots the change in the share of adults (25+) employed in occupations that were at the given percentile of the adult (25+) wage distribution in 1984-1986. Lines are smoothed using the "lowess" function of Stata with a bandwidth of .8. All statistics are computed from CPS outgoing rotation group microdata.

Note: Counterfactual employment-population rates predict the change in the emp-pop rate for 16-24 year olds from a regression of the change in emp-pop on three lags of the change in the CBO's estimate of the GDP gap the change in emp-pop for 24-54 year olds and the interaction of the changes in the GDP gap and lags and the change in adult emp-pop. The predicted change in emp-pop for 16-24 year olds is applied to the level of the emp-pop in 1990 to form the counterfactual emp-pop. The counterfactual emp-pop for 16+ uses the counterfactual emp-pop for 16-24 and the actual emp-pop for 25+.
