Geographies of Intergenerational Immigrant Labour Markets International Population Geographies Conference University of Liverpool June 2006 Jamie Goodwin-White Division of Social Statistics School of Social Sciences University of Southampton
Theoretical Background Concern with how immigrants and their children are doing over time and across generations Spatial dimensions of immigrant economic progress (Waldinger, Clark, Ellis, Zhou 2001) Local contexts of labor market inequality (McCall 2001, Bound and Freeman 1992)
Questions Does the geography of immigrants matter for estimating wages and wage gaps?
Questions Does the geography of immigrants matter for estimating wages and wage gaps? Is there a selectivity to internal migration that relates to wage outcomes? Is it different for immigrants and natives? How?
Models 1: Geographically Weighted Regression Does the geography of immigrants matter for estimating wages and wage gaps? How to weight population to account for different spatial distributions
Geo-weighted Regressions: Data and Methodology year-old men from 5% PUMS (currently employed, and with positive wages and hours data) Split into immigrant Mexicans and native-born whites
Covariates and weights Ln(hourly wage) Age, education (+ fb interactions), married, years of experience (age-5-educ), arrival cohort (for fb) Model iterations with 1) pweight and 2) mexweight mexweight: proportion of fb mex (by metro) used to weight regression
Findings Geoweighted models show: 1) 1) higher wages for both groups 2) 2) wage penalty to immigrants increases slightly General models predicted logged hourly wage: pweightmexweight nbw2.31 ($10.15)2.40 ($10.98) fbm-.18 ($8.51)-.21 ($8.94)
Additional findings: covariates Significant and dramatic wage penalty to recent arrivals in geoweighted models
Additional findings: covariates Significant and dramatic wage penalty to recent arrivals in geoweighted models Significantly reduced wage penalty to those native whites with less than college education
Additional findings: covariates Significant and dramatic wage penalty to recent arrivals in geoweighted models Significantly reduced wage penalty to those native whites with less than college education Large returns to BA increase sizably in geoweighted models - especially for immigrants
Summary: Distinctive Contexts of Immigrant Geographies Does the geography of immigrants matter for estimating wages and wage gaps? Yes, areas where immigrant (Mexicans) live are higher waged but more unequal But much of this penalty is for recent arrivals Payoffs to higher education, especially for immigrants - and fewer penalties for least-educated when recent arrivals taken into account
Models 2: Heckman Selectivity Models Is there a selectivity to internal migration that relates to wage outcomes? Is it different for immigrants, their second generation adult children and natives? How? In other words, are those who move likely to be those who expect to benefit from the move?
Models 2: Heckman Selectivity Models Two-step models: Probit on instrumental variable migration (moved at metro level last 5 years) Selectivity parameter (lambda or inverse mills ratio) comes from taking unmeasured variance from this model and using as covariate in OLS wage model
Heckman Migration-Selectivity Models: Data and Methodology year-old men from 2000 PUMS (currently employed, and with near full-time full-year data) Split into immigrants, natives, and 1.5 generation
Two-stage covariate selection Wage models include: race(white,black, asian,hispanic, other), age, education (BA), lambda Migration models also include: family size, new employment growth, and percent immigrant
Findings Initial OLS: age, education, race generally work as expected. Immigrant Hispanics and native Blacks fare particularly poorly. 1.5 Generation Hispanics, whites, Blacks fare better then native-born counterparts. Wages have very slight negative relationship to move Heckman selectivity-corrected models show strong positive selectivity effect of migration on wages =0.42 (native-born), ~ =.20 (immigrants and 1.5 generation)
Changes due to migration selectivity controls BA degree effect stronger still in Heckman models - underestimated without migration selectivity controls (especially for immigrants) Much of penalty to being Hispanic ( for immigrants, and 1.5 generation only) abated by controlling for migration selectivity =0.42 (native-born), ~ =.20 (immigrants and 1.5 generation)
Changes due to migration selectivity controls BA degree effect stronger still in Heckman models - underestimated without migration selectivity controls (especially for immigrants) Much of penalty to being Hispanic ( for immigrants, and 1.5 generation only) abated by controlling for migration selectivity =0.42 (native-born), ~ =.20 (immigrants and 1.5 generation) Immigrant concentration has slight negative effect on wages, but not for native-born
Summary Is there a selectivity effect on how migration effects wages? Yes - and a strongly significant one. It is stronger (more efficient for natives than the foreign-stock). Uncorrected wage regression models show negative bias to migration’s effect on wages. Migration is a way in which immigrant and 1.5 generation Hispanics attenuate severe wage penalties relative to the native- born. Or not. Strong payoffs to BA, especially for immigrants, indicate that internal migration could also be an intergenerational labor market strategy.
Conclusions It is critical to understand immigrant and second generation geographies when assessing immigrant economic incorporation. Internal migration and different group’s selectivity thereof is part and parcel of this. Proximity to co-ethnics or other immigrants is only part of the equation on immigrants’ residential patterns and labor market outcomes - especially over time and for the second generation.
