Hispanics in the U.S. labor force are the subject of the studies in this volume. After an introduction by George J. Borjas and Marta Tienda, the first three papers focus on the same issue: the determination of wage rates for Hispanics and comparison of Hispanic and non-Hispanic wage rates. Cordelia Reimers compares the situation for Black, White, and Hispanic males; John Abowd and Mark Killingsworth examine the situation in the Federal and non-Federal sectors; and Steven Myers and Randall King look at youth wage rates. In subsequent papers, Gregory de Freitas examines differences in both the incidence and duration of unemployment among Hispanic men and between Hispanic and non-Hispanic Whites; Stanley Stephenson, Jr., focuses on how individual and market characteristics influence the unemployment rates of Hispanic youth; Neil Fligstein and Roberto Fernandez compare the determinants of high school completion for Mexican-Americans and Whites; and Frank Bean, Gray Swicegood, and Allan King consider how the high fertility rate of Hispanic women influences their labor market behavior and whether nationality produces different patterns of fertility-labor market relationships among Mexican, Puerto Rican, and Cuban-origin women. Finally, Harley Browning and Nestor Rodriguez deal with the process by which undocumented Mexican workers integrate themselves into U.S. society and its labor market. (CMG)
