Thus,if concerns about labor-market competition are critical determinants of immigration preferences,given the large gap in average skills between immi- grants from richer and poorer countries,we should expect that respondent skill levels should have a substantially different effect on answers to the ESS questions about immigration from richer and poorer countries.Respondent skill levels should have a large and positive effect on support for immigration from poorer countries, since these are predominantly low-skilled immigrants who compete for jobs with low-skilled natives.This is in line with the proposition tested in previous studies. But respondent skill levels should have a substantially smaller,and perhaps even a negative,effect on support for immigration from richer countries,since these are predominantly high-skilled immigrants who are substitutes(rather than com- plements)to native workers with high skills.In Table 1 we have reported educa- tion levels of natives(the ESS sample)to compare with those of different types of immigrants.By this simple measure,immigrants from poorer countries(both from within and outside Europe)are,on average,less skilled than the ESS natives,while immigrants from richer countries are more highly skilled than natives.While these relationships can vary according to the education levels of natives within each particular ESS country,the large skill gap between immigrants from richer versus 39.These categories match the EDUCATIONAL ATTAINMENT measure in the ESS data that we employ below with the exception that van Tubergen also includes PHDs in the high education category rather than coding them separately. 40.This supplement is available at the authors'Web site at (http://www.people.fas.harvard.edu/ ~jhainm/research.htmI).It provides a detailed breakdown of education levels in each ESS country and compares these with education levels of immigrants to ESS countries using the van Tubergen data

Asummary of the ESS data on immigration preferences is reported in Table 2.41 On average,survey respondents prefer European immigrants to non-Europeans (holding wealth constant),as perhaps we might expect,and they prefer immi- grants from richer countries to those from poorer countries (holding "European- ness"constant).42 The most preferred immigrants are thus those from richer European nations;the least preferred are from poorer countries outside Europe.

Labor-Market Competition and Anti-Immigration Views? Benchmark Model To provide a basic test of the conventional labor-market competition argument, we estimate a series of probit models for the dichotomous dependent variables described above (indicating support for immigration from different types of source countries).We employ the two indicators of individual levels of education that have been applied as proxy measures of individual skill levels in previous studies: the first measure,YEARS OF SCHOOLING,simply counts the total number of years of full-time education completed by the respondent;the second measure,which we label EDUCATIONAL ATTAINMENT,is a categorical indicator of the highest level of education attained by the respondent,adjusted by the ESS to allow for differ- ences between the various European educational systems so that the results are comparable across countries.43(See Table Al,p.438 for complete descriptive sta- tistics for all variables described here and used in the analysis). We include the standard socioeconomic and demographic control variables in an otherwise streamlined "benchmark"model.These variables include the respondent's AGE (in years),GENDER (1 female,0=male),and INCOME (mea- sured on a categorical scale from 1 to 12).44 We include whether the respondent is a NATIVE of his or her country of residence (1 born in country;0=foreign born),for obvious reasons.To account for "neighborhood"effects,we include a 43.The coding is:0=not completed primary education;1 completed primary or first stage of basic education;2=completed lower secondary or second stage of basic education;3 completed upper secondary;4=postsecondary,nontertiary:5=first stage of tertiary;and 6=completed second stage of tertiary education. 44.Since individual income is correlated with education,one could make the case for excluding it from the benchmark model when assessing aggregate effects of educational attainment on attitudes toward immigrants.Mayda 2006;and Scheve and Slaughter 2001a estimated models with and without an income control.We report estimations including income here but have replicated all the analysis after excluding the income variable-the results (available from the authors)are virtually identical. The coding for income is:1=less than€150 monthly;2=€150-30;3=300-500;4=500-1000; 5=1000-1500:6=1500-2000:7=2000-2500:8=2500-3000:9=3000-5000:10=5000-7500: 11=7500-10000:12=>10000
