As these losses have become increasingly apparent, policy makers have significantly expanded resources for retraining, much of which takes place in regular community college classes. To analyze the effectiveness of such training, we link administrative earnings records with the community college transcript records of workers displaced from jobs during the first half of the 1990s in Washington State. We explore several issues of statistical specification for regression models quantifying the impact of community college credits on earnings. These include (i) how to allow for a transition period immediately after the end of workers' schooling when their earnings may be temporarily depressed, (ii) whether earnings gains are strictly proportional to credits earned, and (iii) how to model worker-specific unobserved heterogeneity. In our preferred specification, we find that the equivalent of an academic year of community college schooling raises the long-term earnings of displaced workers by an average of about 9 percent for men and about 13 percent for women. However, these average returns mask substantial variation in the returns associated with different types of courses. On the one hand, we estimate that an academic year of more technically oriented vocational and academic math and science courses raise earnings by about 14 percent for men and 29 percent for women. On the other hand, we estimate that less technically oriented courses yield very low and possibly zero returns. About one third of the increase in earnings associated with more technically oriented vocational and academic math and science courses is estimated to be due to increases in wage rates, with the remainder attributable to increased hours of work.JEL Classification: J31

The authors estimate the returns to retraining for older displaced workersthose 35 or older-by estimating the impact of community college schooling on earnings. The analysis relies on longitudinal administrative records covering workers displaced from jobs in Washington State during the early 1990s. The authors find that older displaced workers participated in community college schooling at lower rates than younger workers. Among those who participated, however, the impact on quarterly earnings was similar across the two age groups.One academic year of community college schooling is estimated to have increased long-term earnings by about 7% for older men and by about 10% for older women. Although these percentages are consistent with those reported in the schooling literature, estimates of the social internal rates of return from this retraining may differ substantially among older and younger workers because of differences in their work lives and their opportunity costs of retraining. uring the past decade there has been uring rising interest in policies that foster human capital investment in young chil-dren.' Proponents of these policies point to evidence that such investments produce impressive returns, even though much of the social benefit is not apparent until adolescence or young adulthood. Even as this evidence has been accumulating, policymakers have directed more of their work force development expenditures toward

This paper estimates the returns to retraining for older displaced workers--those 35 or older--by estimating the impact that community college schooling has on their subsequent earnings. Our analysis relies on longitudinal administrative data covering workers who were displaced from jobs in Washington State during the first half of the 1990s and who subsequently remained attached to the state's work force. Our database contains displaced workers' quarterly earnings records covering 14 years matched to the records of 25 of the state's community colleges.We find that older displaced workers participate in community college schooling at significantly lower rates than younger displaced workers. However, among those who participate in retraining, the per-period impact for older and younger displaced workers is similar. We estimate that one academic year of such schooling increases the long-term earnings by about 8 percent for older males and by about 10 percent for older females. These per-period impacts are in line with those reported in the schooling literature.These percentages do not necessarily imply that retraining older workers is a sound social investment. We find that the social internal rates of return from investments in older displaced workers' retraining are less than for younger displaced workers and likely less than those reported for schooling of children. However, our internal rate of return estimates are very sensitive to how we measure the opportunity cost of retraining. If we assume that these opportunity costs are zero, the internal rate of return from retraining older displaced workers is about 11 percent. By contrast, if we rely on our estimates of the opportunity cost of retraining, the internal rate of return may be less than 2 percent for older men and as low as 4 percent for older women.
