   Sammanfattning : Chapter 1: Impact of School Peers from the Same Region-of-Origin on Endogamy and Work Segregation: Evidence from Sweden This study estimates how the quasi-random variation in the proportion of school peers from the same Region-of-Origin (ROO) affects the probability for an individual to have a partner from the same ROO (endogamy) and the proportion of colleagues from the same ROO in the same workplace later in life (work segregation). This is answered by a fixed effect regression model, together with a unique dataset that merges different register databases from Sweden. LÄS MER

   Sammanfattning : Policy makers often spend considerable amounts of money to attract IKEA to their region despite not having any empirical measurements on its expected contribution to the local economy. As such, an empirical study of the economic and social impact of new IKEA stores can aid political decision making, and contribute to the literature regarding how big-box retail entry affects the regions where they enter.

The testing followed Baron and Kenny s (1986) causal step approach. LÄS MER
