Despite the growth of underemployment in the United States, relatively
little theoretical or empirical attention has been paid to this pheno
menon. This article presents a multidimensional conceptualization of u
nderemployment in terms of education, work duties, field of employment
, wages, and permanence of the job. The article then presents testable
propositions on both the hypothesized antecedents of underemployment
(e.g., economic factors, job characteristics, career history, job sear
ch strategies, and demographics) and on the hypothesized consequences
of underemployment (e.g., job attitudes, overall psychological well-be
ing, career attitudes, job behaviors, and marital, family, and social
relationships). Directions for future theory development, research met
hodology, and institutional assistance programs for the underemployed
are discussed as well.
