Job Polarization and Task-Biased Technological Change: Sweden, 1975–2005
This paper investigates the connection between the Swedish wage profile of net job creation and Autor, Levy, and Murnane’s (2003) proposed substitutability between routine tasks and technology. We first show that between 1975 and 2005, Sweden exhibited a pattern of job polarization with expansions of the highest and lowest paid jobs compared to middle-wage jobs. We then use cross-sectional and longitudinal analyses of job-specific employment to map out the importance of routine versus nonroutine tasks for these changes. Results are consistent with substitutability between routine tasks and technology as an important explanation for the observed job polarization during the 1990s and 2000s, but not during the 1970s and 1980s. In particular, the overrepresentation of routine tasks in middle-wage jobs can potentially explain 44 percent of the growth of low-wage jobs relative to middle-wage jobs after 1990 but largely lacks explanatory power in earlier years.Inequality; Job Mobility; Skill Demand; Skill-Biased Technological Change
Institutions and Practices for Restoring and Maintaining Public Order
The implementation of a copyright protection reform in Sweden in April 2009 suddenly increased the risk of being caught and punished for illegal file sharing. This paper investigates the impact of the reform on illegal file sharing and music sales using a difference-in-differences approach with Norway and Finland as control groups. We find that the reform decreased Internet traffic by 16% and increased music sales by 36% during the first six months. Pirated music therefore seems to be a strong substitute to legal music. However, the reform effects disappeared almost completely after six months, likely because of the weak enforcement of the law
Piracy, Music and Movies: A Natural Experiment
This paper investigates the effects of illegal file sharing (piracy) on music and movie sales. The Swedish implementation of the European Union directive IPRED on April 1, 2009 suddenly increased the risk of being caught and prosecuted for file sharing. We investigate the subsequent drop in piracy as approximated by the drop in Swedish Internet traffic and the effects on music and movie sales in Sweden. We find that the reform decreased Internet traffic by 18 percent during the subsequent six months. It also increased sales of physical music by 27 percent and digital music by 48 percent. Furthermore, it had no significant effects on the sales of theater tickets or DVD movies. The results indicate that pirated music is a strong substitute for legal music whereas the substitutability is less for movies.Copyright protection; Piracy; File sharing; Music; Movies; IPRED; Natural experiment
Har illegal fildelning orsakat minskad skivförsäljning i Sverige? : En empirisk studie
I denna uppsats genomförs en empirisk analys av den svenska skivmarknaden och den nedgång i skivförsäljningen som skett under senare år. Fokus ligger på att undersöka om nedgången orsakats av illegal fildelning, eller om andra faktorer kan ligga bakom. Analysen sker genom en genomgång av relevanta aggregerade data för skivförsäljning, videoförsäljning, internetanvändande m.m. En enkel ekonometrisk analys görs också, och sammantaget visar resultaten att den växande konkurrensen från DVD-film troligen är en viktig orsak till den minskade skivförsäljningen. Inga tydliga bevis för att fildelningen haft en signifikant påverkan hittas. Brist på detaljdata gör dock att alla slutsatser måste tolkas försiktigt
Intergenerational wealth mobility and the role of inheritance: Evidence from multiple generations
This study estimates intergenerational correlations in mid-life wealth across three generations, and a young fourth generation, and examines how much of the parent-child association that can be explained by inheritances. Using a Swedish data set we find parent-child rank correlations of 0.3–0.4 and grandparents-grandchild rank correlations of 0.1–0.2. Conditional on parents’ wealth, grandparents’ wealth is weakly positively associated with grandchild’s wealth and the parent-child correlation is basically
unchanged if we control for grandparents’ wealth. Bequests and gifts strikingly account for at least 50 per cent of the parent-child wealth correlation while earnings and education are only able to explain 25 per cent.JEL: D31, J6

Gig-jobs : Stepping stones or dead ends?
How useful is work experience from the gig economy for labor market entrants searching for traditional wage jobs? We conducted a correspondence study in Sweden, comparing callback rates for recent high school graduates with (i) gig-experience, (ii) traditional experience, and (iii) unemployment history. We also study heterogeneous responses with respect to perceived foreign background. Our findings suggest that gig-experience is more valuable than unemployment, but less useful than traditional experience for majority applicants. Strikingly however, no form of labor market experience increases the callback rate for minority workers
