Differences in community colleges’ missions: Evidence from California

Using data for 108 colleges in the California Community College System, this paper poses two questions. First, do California community colleges differ in their missions? Second, if they do, can inter-college differences in missions be explained? We address the first question by developing college-specific measures of curriculum mix, which we use to characterize colleges as to their curriculum emphases and specializations. We find that colleges differ in the extent to which they offer a transfer specialization or a nontransferable voc-ed specialization. Turning to the second question, we attempt to explain inter-college differences in curriculum emphasis and specialization with institutional variables including student demographics, labor market characteristics, and community characteristics. While not strong, we view our results as suggesting that curriculum emphases and specializations are related to student demographics and community needs.     

The over-education of UK immigrants and minority ethnic groups: Evidence from the Labour Force Survey

The paper explores the incidence of over and under education and the effect on earnings for immigrants and natives who hold UK qualifications, drawn from the Quarterly Labour Force Survey 1993–2003. The paper also compares earnings penalties associated with over and under education across immigrant and minority ethnic groups for men and women. The results show that compared to Whites, Black African, Other Non-White and Indian men are more likely to be over-educated, whilst for women it is Indian and Pakistani/Bangladeshi's who are more likely to be over-educated. Estimating earnings equations shows significantly large over-education penalties for South Asian immigrant and native men, as well as White immigrant men, Black women and White UK born women. However, there are large returns to occupational skills for some minority ethnic and immigrant groups, over and above the returns to qualifications. It is suggested that these groups may therefore find it easier to find a suitable job for their UK education level if higher or further education programmes for immigrants were combined with occupational specific training.     

Overqualification: Major or minor mismatch?

A proportion of employees are overqualified for their work. This generates a wage premium relative to the job but a penalty relative to the qualification, and is therefore. A puzzle for human capital theory. A part of this derives from the use of measures of time spent in education for the calculation of overqualification. Analysing data from four European countries, we split years of education into two components, one reflecting certification, another reflecting time. While a qualification higher than required mostly generates a wage premium, time does not. The result is that the combination of time with excess (or deficit) qualification may make overqualification either a major or a minor mismatch. The probability of either outcome varies with the institutional arrangements of different countries’ educational systems.     

Effort allocation in tournaments: The effect of gender on academic performance in Italian universities

We consider the academic performance of Italian university graduates and their labor market position 3 years after graduation. Our data confirm the common finding that female students outperform male students in academia but are overcome in the labor market. Assuming that academic competition is fair and that individual talent is equally distributed by gender, we suggest that the gender gap evident in degree scores is endogenously due to the greater effort exerted by female students. We find that females face a greater increase in labor market returns from signalling through academic performance. This higher prize explains the greater effort exerted by females and the higher probability of winning the academic competition.     

Non-formal basic education as a development priority: Evidence from Nicaragua

Almost 900m adolescents and adults are illiterate in the developing world, yet most policy discussions focus on the educational circumstances of primary aged children. As a result non-formal educational programs for adolescents and adults are given very little support, and this group is virtually ignored in international agreements such as the millennium declaration. This article presents the first serious attempt at evaluating the impact of a non-formal education program. Results show significant learning achievement over the academic year, as well as strong development impacts of the program in non-learning dimensions of participants’ lives. These positive impacts, plus the significantly lower unit costs and self-targeted nature of the program provide strong evidence that this type of program can be an important part of the poverty reduction and human capital enhancement strategy of developing countries with large illiterate adult populations.     

Am I still too Black for you?: Schooling and secular change in skin tone effects

Analysts disagree about whether the Civil Rights/Black Power eras lessened the influence of skin tone on education. The paper finds that, holding family background constant, the educational disadvantages of dark and very dark blacks persisted between younger and older age cohorts. On the other hand, younger medium skin blacks no longer achieved less schooling than their lighter skin counterparts. This paper implies that, without the decline in skin tone effects for medium brown blacks, the racial gap between age cohorts would have remained larger.     

Teenage dropouts and drug use: Does the specification of peer group structure matter?

Four alternative structures of peer groups are compared in an empirical analysis of teenage dropouts and recent drug use. In general, individual-specific covariates remain robust regardless of group structure specification in dropout models, but lose significance in models of drug-use. Estimates of correlated school effects depend on the specification of group structure. Contextual group effects have no influence on the probability that an individual uses drugs, but demonstrate some statistical significance, albeit ambiguous and strongly dependent on the specification of group structure. Endogenous peer effects do not influence the probability of dropping-out of school, but exhibit positive complementarities with respect to recent drug-use. Modeling the probabilities of leaving school and recent drug-use within a jointly distributed empirical framework indicates that unobserved attributes bridging the two types of behavior demonstrate positive correlation.     

Monetary returns to academic ability in the public teacher labor market

Previous research has established the returns to academic ability in the general labor market, and this paper investigates such returns in the teacher labor market. Using a nationally representative sample of public school teachers, I find that teachers who graduate from the most selective undergraduate institutions have salaries that are between 7% and 14% higher than those who graduate from the least selective colleges. An empirical investigation of the source of these returns reveals that the majority of this difference is due to high-ability teachers sorting into higher paying districts, though a non-trivial amount arises from within-district deviations from the salary schedule.
