Objective. Although various economic and social factors increased the incen
tives for limited-English-proficient (LEP) populations to acquire English f
luency in the 1980s, little empirical work explores whether LEP individuals
reacted to these growing incentives by enhancing their English skills duri
ng this rime. Methods. We address this research void by analyzing changes i
n the English proficiency of Hispanic adults, using synthetic cohorts from
the 1980 and 1990 Public Use Microdata Samples. Results. Our results show t
hat many Hispanics invested in additional English fluency during the 1980s.
Socioeconomic characteristics also appear to influence the accumulation of
English skills; the relative effects of these characteristics correspond t
o the neoclassical reasoning of weighing the marginal costs and marginal be
nefits associated with skill investment. Conclusions. These findings indica
te the potential for enhanced socioeconomic outcomes for Hispanics, and sho
uld ease some concern about the linguistic polarization of American society
.
