This dissertation consists of three essays in Labor Economics. The first chapter estimates the costs for establishments of hires and separations for a panel of German establishments. The panel records the start and the termination of the employment of all employees in the surveyed establishments, allowing estimation of adjustment costs under different assumptions of how frequently establishments revise their labor demand. Under the assumption that establishments revise their labor demand every month, estimates suggest hiring costs per employee of approximately 5,000 Euros, and costs of separations of 1,000 Euros. Hiring costs vary considerably between skilled (8,000 to 28,000 Euros per hire) and unskilled (4,000 to 8,000 Euros) labor. Spatial aggregation (large establishments) is associated with lower cost estimates, and only monthly adjustment frequencies yield estimates consistent with theoretical predictions. The second chapter analyzes the role of regional ethnic capital - defined as the average years of schooling of ethnic groups - in the educational attainment of young second generation immigrants in Germany using information on naturalization and country of birth in a nationally representative survey. I find evidence for externalities of ethnic capital for ethnic groups. A higher average education of ethnics makes attendance of higher-quality secondary schools more likely. Moreover, the effect is mainly mediated through the ethnic concentration in the region. However, if higher than regional aggregates are used for the measurement of ethnic capital, no externalities are detected. The third chapter analyzes the impact of regional own-ethnic concentration on the language proficiency of immigrants in Germany. It solves the endogeneity of immigrants' location choices by exploiting the fact that guest-workers in Germany after WWII were initially placed by firms and labor agencies. We find a robust negative effect of ethnic concentration on immigrants' language ability. Simulation results of a simultaneous location and learning choice model confirm the presence of the effect and show how immigrants with high learning cost select into ethnic enclaves. Under the counterfactual scenario of a regionally equal distribution of immigrants the share of German-speakers increases only modestly. / text

Much of the public policy discourse about immigration in the UK has drawn on the experiences of post-war immigrants from the former British colonies. The volume and composition of immigration flows has changed significantly in recent years with substantial increases in the number of immigrants, particularly from countries without links to the UK, and as a result of the large scale immigration from the EU Accession countries in Central and Eastern Europe. Immigration remains a contested issue with public and political debates focusing on the nature and impact of immigration and its perceived negative effects on employment, public services and social cohesion. In spite of the growing number of studies examining the experiences of new immigrants in local neighbourhoods and labour markets there is a lack of comprehensive evidence about how these experiences differ across immigrant groups and the role of place in shaping the experiences and outcomes of new immigration. This research draws on a variety of data from the census, national surveys, administrative sources and qualitative interviews to explore the settlement patterns, labour market outcomes and neighbourhood experiences of new immigrants. The findings show that new immigrants are more likely to locate in ethnically diverse and socially deprived neighbourhoods upon arrival although there is variation in the factors determining immigrant settlement by world area of origin in line with differences in migration motives and entitlements in the UK. The findings from the qualitative interviews highlight the range of motivations and constraints that shape immigrant settlement patterns and how these change over time with secondary migration and family formation. Analysis of the labour market position of immigrants defined by country of origin and ethnicity shows the persistence of ethnic penalties in the labour market. Immigrants from ethnic minority groups both from established and new immigrant groups are found to be more disadvantaged in the labour market than white immigrants and the White British. The neighbourhood context, specifically neighbourhood deprivation and ethnic diversity, is associated with poorer employment outcomes, with the relationship between area deprivation and employment shown to depend on ethnicity. The qualitative evidence highlights the role of social networks and a range of other factors in facilitating and hindering the socio-economic integration of new immigrants. The findings, particularly in relation to immigrant social networks, access to welfare, settlement intentions and housing aspirations, challenge common perceptions about new immigrants living in deprived areas in the UK. The research evidence contributes to a better understanding of the settlement patterns and experiences of new immigration and has implications for national and local policies.

From the moment children are born, they begin a lifetime journey of learning about themselves and their surroundings. With the establishment of the No Child Left Behind Act of 2001, it mandates that all children receive a high-quality education in a positive school climate. Regardless of the school the child attends or the neighborhood in which the child lives, proper and quality education and resources must be provided and made available in order for the child to be academically successful. The purpose of this ex post facto study was to investigate the relationship between the FCAT 2.0 mathematics scores of public middle school students in Miami-Dade County, Florida and the concentrations of a school’s racial and ethnic make-up (Whites, Blacks, and Hispanics), English for Speakers of other Languages (ESOL) population, socio-economic status (SES), and school climate. The research question of this study was: Is there a significant relationship between the FCAT 2.0 Mathematics scores and racial and ethnic concentration of public middle school students in Miami-Dade County when controlling SES, ESOL student population, and school climate for the 2010-2011 school year? The instruments used to collect the data were the FCAT 2.0 and Miami-Dade County Public Schools (M-DCPS) School Climate Survey. The study found that Economically Disadvantaged (SES) students socio-economic status had the strongest correlation with the FCAT 2.0 mathematics scores (r = -.830). The next strongest correlation was with the number of students who agreed that their school climate was positive and helped them learn (r = .741) and the third strongest correlation was a school percentage of White students (r = .668). The study concluded that the FCAT 2.0 mathematics scores of M-DCPS middle school students have a significant relationship with socio-economic status, school climate, and racial concentration.
