Factors that affect work outcomes of high school youth and effects of the characteristics of the school that a youth attends on employer demand were studied. It was hypothesized that employers use the quality of the school as a proxy for accurate information about likely productivity of prospective employees. Four dependent variables were examined--hours of work per week, labor force participation, wage rate, and unemployment. A model of hours worked and labor force participation was derived from utility theory of labor supply. Data from 28,000 secondary and postsecondary seniors showed that wage and nonwage benefits of work tended to increase the supply of hours of teenage youth attending school. Commitment to schooling tended to reduce the hours worked. Empirical tests of the school-effects hypotheses failed to support them. These results may have been due to the relatively homogeneous quality of high schools within the geographical limits from which employers typically hire teenage workers. Findings regarding the effects of other school variables were that attending a vocational or private school increases one's wages, cooperative education and work study tend to improve one's experience in the part-time youth labor market, and black students experience higher unemployment.
