The study develops a labor market success model of young male inner-city Hispanics and examines several variables influencing labor market success. A sample of inner-city Puerto Ricans who attended the eighth grade in two schools in Wilmington, Delaware, in the 1966-1971 period was chosen and interviewed. Small control groups of blacks and whites were used also. Two multiple regression models of success are developed; one uses highest wage and the other uses the wage adjusted for job stability and type of job as dependent variables. The significant major determinants of success are years of school, number of children, and race. Attitude toward work, extent of career planning, and years lived in Puerto Rico also can influence success. Puerto Rican young men do worse than blacks and much worse than whites in the labor market. Other forms of human capital investment, including job training, do not seem to matter. Unemployment is high but is voluntary. The young man sees racial discrimination hindering his labor market progress. To raise the success level, public policy should focus on making schools and job training more effective, provide better counseling and market information, and expand the availability of "good jobs." Present macro-economic job programs are of little value. (Author)
