Regional sorting of human capital : the choice of location among young adults in Sweden
- 2014
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Migration rates are highest among young adults, especially students, and their location choices affect the regional distribution of human capital, growth and local public sector budgets. Using Swedish register data on young adults, the choice of whether to enroll in education and the choice of location are estimated jointly. The results indicate a systematic selection into investment in further education based on school grades and associated preferences for locations with higher per capita tax bases. For students, the estimates indicate lower preferences for locations with higher shares of older people. The importance of family networks for the choice of location is confirmed.

Amyloid fibrils as dispersing agents for oligothiophenes: control of photophysical properties through nanoscale templating and flow induced fibril alignment

- Herein we report that protein fibrils formed from aggregated proteins, so called amyloid fibrils, serve as an excellent dispersing agent for hydrophobic oligothiophenes such as alpha-sexithiophene (6T). Furthermore, the protein fibrils are capable of orienting 6T along the fibril long axis, as demonstrated by flow-aligned linear dichroism spectroscopy and polarized fluorescence microscopy. The materials are prepared by solid state mixing of 6T with a protein capable of self-assembly. This results in a water soluble composite material that upon heating in aqueous acid undergoes self-assembly into protein fibrils non-covalently functionalized with 6T, with a typical diameter of 5-10 nm and lengths in the micrometre range. The resulting aqueous fibril dispersions are a readily available source of oligothiophenes that can be processed from aqueous solvent, and we demonstrate the fabrication of macroscopic structures consisting of aligned 6T functionalized protein fibrils. Due to the fibril induced ordering of 6T these structures exhibit polarized light emission.

All in the Family : self Selection and Migration by Couples

- This paper examines determinants of couple migration in a model that accounts for self-selection of migrant couples. The study is based on a sample of married couples from the Swedish population. The model incorporates controls for earnings of both spouses preceding the move, and explicitly addresses unmeasured heterogeneity in the family decision to migrate. Two statistical formulations are presented. In the first version, migration is measured as a dichotomous move/stay decision. A second formulation replaces the dichotomous indicator with the distance moved by migrants. Results suggest that family migration is selective of relatively low earning wives with unmeasured potential for strong earnings.

Tidskriftsartikel (refereegranskat)abstract
- This paper addresses the impact of active labor market programs on interregional migration in Sweden. The purpose of the study is to determine the extent to which the programs, which provide training and labor market assistance to jobless individuals, induce participants to migrate. Analysis is based on data registers compiled in 1994 and 1995 by Statistics Sweden and the Labor Market Board of Sweden. The paper specifies and estimates a two-equation model of participation and subsequent migration. The model, which is estimated by the method of maximum simulated likelihood, accounts for the role of program participation as an endogenous choice variable in the decision to migrate. In an attempt to capture the effect of migrant self-selection, the estimation approach also controls for unobserved heterogeneity in the participation and migration equations. Results of the study indicate a significant positive impact of participation on subsequent mobility for males. This result is robust with respect to alternative specifications of the migration equation and alternative formulations of the model for program participation. For females, the evidence of program impacts is mixed and it appears to be sensitive to the statistical formulation of the model.

Is your commute killing you? : On the mortality risks of long-distance commuting
- 2014

Tidskriftsartikel (refereegranskat)abstract
- There is a general belief that expanding labour-market regions, triggered by increased commuting, have positive economic effects on individuals, firms, and society. Recently, however, scholars have reported possible negative outcomes related to health and well-being. Based on these findings, this study addresses the association between long-distance commuting, and mortality. Using longitudinal individual data from between 1985 and 2008, focusing on 55-year-olds in 1994, we model mortality through propensity score matching and Kaplan–Meyer estimates of survival among long-distance commuters and matched controls from the population travelling short distances to work. The results indicate that women who have experienced long-distance commuting face a significantly higher mortality risk compared with women with short commutes to work. This seems to be driven by variations in income and education: for example, for women with long-distance commuting experience, substantially lower survival rates are found among those with low education and low income. A very different picture emerges for men, for whom mortality risks do not seem to be associated with long-distance commuting. Our findings suggest that men and women are subject to different mechanisms regarding the nexus between commuting and mortality.

Can adult education delay retirement from the Labour Market?
- 2012

-
Tidskriftsartikel (refereegranskat)abstract
- We examine whether adult education delays retirement to potentially increase labour force participation among the elderly, a mechanism suggested in the OECD strategy for “active ageing” and the “Lisbon strategy” of the EU. Using register data from Sweden, we analyse transcripts from adult education for the period 1979–2004 and annual earnings 1982–2004. We match samples of treated individuals, in adult education 1986–1989, and untreated on the propensity score. The timing of exit from the workforce is assessed by non-parametric estimation of survival rates in the labour force. The results indicate no effects of adult education on the timing of retirement.

Does formal education for older workers increase earnings? : evidence based on rich data and long-term follow up
- 2014

Tidskriftsartikel (refereegranskat)abstract
- Governments in Europe, Canada and the US have expressed an ambition to stimulate education of older. In this paper, we analyze if there are effects on annual earnings of formal education for participants aged 42-55 at the time of enrolment in 1994-1995. The analysis explores longitudinal population register data stretching from 1982 to 2007. The method used is difference-in-differences propensity score matching based on a rich set of covariates, including indicators of health and labor market marginalization. Our findings underline the importance of long follow up periods and imply positive effects for females, especially so for women with children, and no significant average earnings effects for males. These results differ from earlier studies but are stable to several alternative assumptions regarding unobservable characteristics. Data further indicate that the gender gap in our estimates may stem from differences in underlying reasons for enrolment.
