- An
Analysis of the Earnings of Skilled
Foreign-Born Females: Do Skilled Immigrant Women Experience an
Double Earnings Penalty?
Abstract.
Although a large literature exists on the U.S. labor market
experiences of low-skilled immigrant men, relatively few studies
have examined the labor market position of highly skilled immigrant
women. Census data indicate that between 1990 and 2000, the
percentage of foreign-born women with a Bachelor’s degree or higher
increased by 43.1 percent, compared to an increase of just 21.6
percent among foreign-born men. In addition, in 2000, highly skilled
immigrant women earned 32 percent less than highly skilled immigrant
men, 30 percent less than highly skilled native men, but 9 percent
more than highly skilled native women. The current study explores
the issue of labor market discrimination and examines the extent to
which highly skilled immigrant women experience an earnings
disadvantage as a result of both gender status and nativity status
(U.S. born or foreign-born). Relying on the 2000 Decennial Census
5-percent Public Use Microdata Sample, this study uses an augmented
Oaxaca decomposition technique to decompose the earnings
differential between highly skilled immigrant women and highly
skilled native men into the portion that is attributed to
differences in endowments and the portions that are attributed to
gender status and nativity status. Controlling for sample selection
bias, the decomposition results suggest that highly skilled
immigrant women do experience a double earnings penalty. In
addition, the findings suggest that nativity status explains a
larger portion of the double earnings penalty than nativity status.

High-Skill Immigrants in the U.S. Economy: An Analysis of the Impact
of High-Skill Immigrants on Native Earnings
Abstract. A
large literature exists on the labor market experiences and economic
impacts of less skilled immigrants. With the primary emphasis on
less skilled immigrants, high-skill immigrants are a less studied
segment of the foreign-born population. However, as global
competition for the “best and the brightest” workers continues to
remain strong and developed countries continue to adjust their
immigration admission policies to accommodate talented and skilled
foreign students and workers, further analysis of the economic costs
and benefits of increased global migration of the highly skilled is
warrant. For host countries, at issue is whether skilled immigrants
are a greater source of talent that contributes to innovation and
productivity, or a greater source of competition that creates
displacement and adverse wage impacts for native workers. This study
contributes to the growing literature on the labor market impacts
and experiences of high-skill immigrants by examining the extent to
which high-skill immigrants have an impact on the earnings of
high-skill U.S. natives across occupations. Drawing on pooled,
cross-sectional data from the 1995-2002 Current Population Survey
(CPS) Annual Social and Economic Supplements (ASES) (formerly the
Annual Demographic Survey Supplement) and using both OLS and IV
approaches, the findings suggest a positive impact of high-skill
immigrants on native earnings with the largest positive impact
coming from foreign-born non-U.S. citizens. A 10-percent increase in
the number of high-skill immigrants results in a 2.2 percent
increase in the earnings of U.S. natives and a 10-percent increase
in the number of foreign-born, non-U.S. citizens results in a 7.6
percent increase in native earnings.
- Incorporating Service Learning
into
Economics Courses
Abstract.
Economists have long regarded the “talk and chalk”
method to be the most efficient way to teach economics to
undergraduate students. However, research on active-learning
pedagogies suggests that most students comprehend and retain
economic concepts better when they encounter them or use them
actively, as in classroom debates, role-playing scenarios,
experiments, and data-based problem solving exercises. A promising
but seldom used active-learning technique for the economics
classroom is service-learning. Service-learning courses provide
students the opportunity to apply and relate economic concepts and
theories to real-world experiences within the community and to
reflect on the relationship between theory and practice. One form of
service learning is student-based instruction, which involves
college students teaching economics in the neighboring community,
such as to high school or middle school students or community
residents. This paper provides a detailed application of the
student-based instruction form of service-learning to an Economics
of Race and Gender course taught at Occidental College in spring
2006. The student-based instruction project required Occidental
students to team-teach a topic covered in the course to students at
a local high school. Upon completion of the project, students
completed a survey about their learning experiences. The results
indicated that service-learning enhanced learning and created a more
enriching course experience.
- Formal Citizenship or Cultural
Citizenship?:
The Case of Mexican Immigrants in Los Angeles
County (with Dolores Trevizo)
Abstract. Using
mixed methods, we explore the meaning and economic impact of legal
status among Mexican immigrants in Los Angeles County. On the basis
of a qualitative analysis of the recent nativist backlash against
Mexicans immigrants, we argue that cultural citizenship does not
have the power to constitute real membership into the community.
Because norms and attitudes vary with time, place, and social actor,
we argue that culture is too fluid and contradictory to constitute
the kind of real membership implied in the concept “cultural
citizenship”. Further, we show that non-naturalized immigrants
living in poverty make below the legal minimum wage despite L. A.
County’s historic inclusivity of Mexicans. With U.S. Census data we
demonstrate that the lack of citizenship status carries an earnings
penalty for immigrants, even when holding constant human capital and
other observable characteristics. Those who naturalized, in
contrast, earned a wage above their true market value, all else
being equal. It follows that formal citizenship has the power to
protect immigrants in their everyday lives in more consistent a way
than cultural citizenship.
