Ratio Working Paper No. 219. Migrationsflöden och regional attraktivitet

Abstract

I denna studie testas två hypoteser kring potentiella effekter av inhemsk och internationell migration avseende löneskillnader. En hypotes behandlar lönekonkurrens och den andra fasta startkostnader och odelbarhet för olika typer av branscher på den lokala arbetsmarknaden. Med hjälp av detaljerad information om den svenska arbetsmarknaden, som härrör från befolkningsdata för 1993 och 2003, uppskattas en panelmodell vad gäller förändringar i ojämlikhet (procent). Efter att kontrollerat för fixa effekter på lokal nivå samt andra konkurrerande förklaringar, tyder resultaten på att en positiv nettomigration kan påverka ökad inkomstspridning oavsett eventuell negativ lönekonkurrens.

Abstract

Using geo-coded full-population grid-level data for the three largest metropolitan areas in Sweden, 1993-2016, this paper i) estimates the level and pace of ethnic segregation, ii) examines possible tipping points in this development, and iii) gauges the importance of several mitigating or exacerbating factors (such as the mix of housing area tenure type, different types of amenities, and crime). We use OLS and 2SLS to estimate outcomes at two different geographic levels; 250 x 250 square meter grids and SAMS areas (roughly equivalent to US census tracts), respectively. On average, we find that for every 1 percentage point increase in immigration, native growth is reduced by around -0.3 percentage points. Crime levels exacerbate developments and factors such as housing area tenure-type mix and access to various amenities slows it down, but only marginally so. Using repeated and single random sampling for cross-validation, and the twin common methodological approaches as suggested in the literature, we estimate possible tipping points in these segregation developments. In contrast to most other studies in the literature, none of our potential tipping points are however statistically significant when probing their relevance in explaining factual population developments, suggesting a rather more continuous – albeit steeply so – segregation process rather than a structural brake. In terms of tipping point methodology, our main findings are that fixed-point estimation is less robust than R-square maximization for small geographical units, and that the former consistently selects for lower tipping-point candidates than the latter.

Abstract

We use full-population data to study trends in intergenerational absolute income mobility, measured as the ratio of children earning more than their parents, for 11 Swedish cohorts born 1972-1983. Absolute mobility during this period increases from 72% to 84% for men and from 76% to 86% for women-higher figures than in most other countries studied. To explain these results, we outline a novel decomposition strategy that accounts for cohort variation in parent-generation income inequality. All else equal, if income inequality is higher in the parent generation, more economic growth is required to achieve any given level of absolute mobility. We discuss implications for comparative research in intergenerational income mobility.

Abstract

The Covid-19 pandemic has made it clear that the labour market situation can change
extremely rapidly when there is an unexpected exogenous shock to the economy. Even
though the transformation of the labour market as a result of the development of ICT
(Information Communication Technology) industries facilitates more-flexible
conditions, it is now more important than ever for EU Member States to improve the
functioning of their labour markets. Member States need to increase possibilities for
training and retraining throughout peoples’ working lives in order to smooth the
transformation into a digital world of work.
