Using the Beginning Postsecondary Student Survey and Transcript Data, we find no statistically significant differential return to certificate or Associate's degrees between for-profits and not-for-profits. Point estimates suggest a slightly lower return to a for-profit certificate and a slightly...

We study roughly 11,000 loans from unlicensed moneylenders to over 1,000 borrowers in Singapore and provide basic information about this understudied market. Borrowers frequently expect to repay late. While lenders do rely on additional punishments to enforce loans, the primary cost of not...

Most integration programs transfer students between schools within districts. In this paper, we study Metco, a long-running desegregation program that sends mostly Black students out of the Boston public school district to attend schools in more affluent suburban districts. Metco increases the...

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

Efficiency wage models have been criticized because worker malfeasance can be prevented in a pareto efficient manner by requiring workers to post a bond which they lose if they are caught cheating. However, since it is costly to monitor workers and costless to demand a larger bond, firms should...

Studies of the earnings of union workers have consistently shown that they earn considerably more than nonunion workers. This paper considers whether part of this observed union/nonunion differential is due to unions organizing high paying primary sector jobs. We extend our earlier work on the...

This paper replicates and extends our earlier analysis of dual market theory. We use a technique which estimates for each worker a probability of being in the primary sector on the basis of his characteristics. We use this information to determine the occupational and industrial composition of...

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...
