Using the Beginning Postsecondary Student Survey, we examine the effect on earnings of obtaining certificates/degrees from for-profit, not-for-profit, and public institutions. Students who enter certificate programs at any type of institution do not gain from earning a certificate. However,...

Although both economists and psychometricians typically treat them as interval scales, test scores are reported using ordinal scales. Using the Early Childhood Longitudinal Study and the Children of the National Longitudinal Survey, we examine the effect of order-preserving scale transformations...

Using data from three cycles of the National Survey of Family Growth, we investigate whether there were adverse consequences of teenage childbearing in the 1950s and 1960s, when most abortions were illegal, and access to the pill was limited. We find negative effects of teen motherhood on the...

We examine the effect of language acquisition on the growth of immigrants' earnings. We gathered data on recent Soviet immigrants to Israel that include retrospective questions on earnings and language ability on entry into their current job. Language acquisition is found to interact positively...

Partly in response to increased testing and accountability, states and districts have been raising the minimum school entry age, but existing studies show mixed results regarding the effects of entry age. These studies may be severely biased because they violate the monotonicity assumption...

We show that increasing the probability of obtaining a job offer through a network should raise the observed wages of workers in jobs found through formal channels relative to those in jobs found through the network. This prediction holds at all percentiles except the highest and lowest. The...

Neoclassical theory has been misrepresented in the segmented economy literature. Consequently, most tests of quot;structuralquot; vs. quot;neoclassicalquot; models are inadequate. Moreover, segmented economy theorists have concentrated on the least significant departures of segmented models from...

We develop a fairly general and tractable model of investment when workers can invest in multiple skills and different jobs put different weights on those skills. In addition to expected findings such as that younger workers are more likely than older workers to respond to a demand shock by...

Despite substantial differences in their views of the appropriate policy response to the existence of poverty, neither the proponents of dual market theory nor its critics have proposed potentially conclusive tests of the dual market hypothesis.This paper presents a test of the two central...

We examine the effect of teenage childbearing on the adult outcomes of a sample of women who gave birth, miscarried or had an abortion as teenagers. If miscarriages are (conditionally) random, then if all miscarriages occur before teenagers can obtain abortions, using the absence of a...
