In this paper we show that the recent model by Duranton (AER, 2007) performs remarkably well in replicating the city size distribution of West Germany, much better than the simple rank-size rule known as Zipf's law. The main mechanism of this theoretical framework is the churning of industries...

The salient rank-size rule known as Zipf's law is not only satisfied for Germany's national urban hierarchy, but also for the city size distributions in single German regions. To analyze this phenomenon, we build on the insights by Gabaix (1999) that Zipf's law follows from a stochastic growth...

We analyze interaction effects of birth weight and the business cycle at birth on individual cardiovascular (CV) mortality later in life. In addition, we examine to what extent these long-run effects run by way of cognitive ability and education and to what extent those mitigate the long-run...

We analyze the impact of family-friendly policies on women?s career breaks due to childbirth in Denmark and Sweden. In both countries, the labour force attachment of mothers is high, and more than 90% of the women return to work after childbirth. Sweden and Denmark are culturally similar and...

This paper discusses the evaluation problem using observational data when the timing of treatment is an outcome of a stochastic process. We show that the duration framework in discrete time provides a fertile ground for effect evaluations. We suggest easy-to-use nonparametric survival function...

We study immigrants in temporary employment agencies in Sweden using a unique data set that covers all aged 16-64 who were employed by temporary employment agencies (TEAs) in Sweden in November 1999, with information on their employment status in 1998 and 2000. We find that young people, women,...

Immigrants have a weak position in the labour market in most European countries. Many have difficulties in establishing themselves in the labour market, the employment rate is low and the hourly wages are generally lower than what could be expected from characteristics (age, gender, education)....

In most industrialized countries the majority of employed people are full-time employees with a non-temporary job and work at a workplace of the company in which they are employed. They are making careers at the employer they are employed by and most work-place changes are to other jobs of the...

We explore the adoption data approach to estimating causal effects of parental education and income on the same outcomes of their children. Thanks to a data set drawn from Swedish population registers with detailed information on biological background and history of adoptees, we can test basic...

It is well known that children reared in non-intact families on average have less favorable educational outcomes than children reared in two-parent families. Evidence from the United States and Sweden indicates that living in a non-intact family is correlated with lower educational attainment....
