Doctoral thesis (other academic/artistic)abstract
- This thesis consists of four papers summarized as follows.Do Payroll Tax Cuts Raise Youth Employment? We study whether payroll tax reductions are an effective means to raise youth employment. In 2007, the Swedish employer-paid payroll tax was cut on a large scale for young workers, substantially reducing labor costs for this group. Using the variation in payroll taxes across cohorts, we estimate a significant, but small, impact both on employment and on wages.Effects of Taxes on Youth Self-Employment and Income. I examine the link between taxes and youth self-employment. I make use of a Swedish reform that made the payroll tax and the self-employment tax vary by age. The results suggest that youth self-employment is insensitive to tax reductions, both in the short run and in the somewhat longer run. For those defined as self-employed, I find positive effects on income from self-employment, and negative effects on income from wage employment.Can Indifference Make the World Greener? We conducted a natural field experiment at a large university in Sweden to evaluate the effects of two resource conservation programs. The first intervention consisted of a campaign that actively tried to convince people to cut back on printing in general, and to use double-sided printing whenever possible. The second intervention exploited people's tendency to stick with pre-set alternatives. At random points in time we changed the printers’ default settings, from single-sided to double-sided printing. Whereas the moral appeal had no impact, the default change cut paper use by 15 percent.The Origins of Behavioral Contagion: Evidence from a Field Experiment on Facebook. We explore the micro-level foundations of behavioral contagion by running a natural field experiment on the networking site Facebook. Members of Facebook express positive support to content on the website by clicking a Like button. We show that users are more prone to support content if someone else has done so before.

Journal article (peer-reviewed)abstract
- We construct multi-country employer-employee data to examine the consequences of last-in, first-out rules. We identify the effects by comparing worker exit rates between different units of the same firms operating in Sweden and Finland, two countries that have different seniority rules. We observe a relatively lower exit rate for more senior workers in Sweden in the shrinking firms and among the low-wage workers. These empirical patterns are consistent with last-in, first-out rules in Sweden providing protection from dismissals for the more senior workers among the worker groups to whom the rules are most relevant. Similarly, we observe a steeper seniority-wage profile in Sweden, suggesting that last-in, first-out rules may also be beneficial for more senior workers in terms of compensation.

Essays on School Resources, Academic Achievement and Student Employment
- 2004

Doctoral thesis (other academic/artistic)abstract
- Essay 1 (with Tanja Kirjavainen and Roope Uusitalo) analyzes the effects of changes in school spending on changes in student performance. We use a large sample of matriculation examination scores of Finnish senior secondary school students from the years 1990–1998. We estimate fixed-effect panel data models that use the dramatic changes in the school spending caused by the 1990s' recession as identifying variation. According to the results, changes in teaching expenditure did not have a significant effect on the test scores. The grade point average in comprehensive school and the parents’ education are the strongest explanatory variables for student achievement.Essay 2 examines which factors predict academic performance at university and compares the predictive values of subject-related entrance exams and indicators of past school performance. The results show that a large fraction of students would be admitted whether the admission was based on entrance exams, past performance or a combination of these, which is the current system. In the fields of engineering, social sciences and sport sciences entrance exams predict both graduation and the number of study credits after four years better than past school performance. In education past school performance is a better predictor of graduation. Changing the admission rule to school grades would affect the average student performance negatively in engineering and social sciences but positively in education. Using only entrance exams would not signifi-cantly change the average student performance in any field.Essay 3 (with Roope Uusitalo) evaluates the changes in the times-to-degree at the Finnish universities in the 1990s. In particular, the study evaluates the effect of the 1992 student aid reform that was intended to shorten the duration of university studies. We find that the student aid reform had only a modest effect, and that this effect was limited to the fields with long median durations. Most of the decline in the observed times-to-degree can be explained by an increase in the unemployment rate that reduced student employment opportunities.Essay 4 examines how university students' employment decisions affect their labor market success after graduation. The study is based on individual level panel data of Finnish university students from the years 1987–1998. The OLS estimates show that in-school work experience is associated with higher earnings and employment after graduation. Local unemployment rate during enrollment is used as an instrument for endogenous work experience acquisition. Comparing graduates with equal times-to-degree, the IV estimates show that work experience increases earnings considerably one year after graduation. The effect is smaller and statistically insignificant in later years. Taking into account that working usually leads to longer times-to-degree, IV estimates show no significant returns to student employment.
