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

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

Dynastic human capital, inequality and intergenerational mobility

We study the importance of the extended family - or the dynasty - for the persistence in human capital inequality across generations. We use data including the entire Swedish population, linking four generations. This data structure enables us to - in addition to parents, grandparents and great grandparents - identify parents' siblings and cousins, as well as their spouses, and the spouses' siblings. We introduce and estimate a new parameter, which we call the intergenerational transmission of dynastic inequality. This parameter measures the between-dynasty variation in intergenerational transmission of human capital. We use three different measures of human capital: years of schooling, family income and an index of occupational status. Our results show that traditional parent-child estimates miss about half of the persistence across generations estimated by the extended model

Why do people file share unlawfully? A systematic review, meta-analysis and panel study

Unlawful digital media sharing is common and believed to be extremely damaging to business. Understanding unlawful file sharers’ motivations offers the opportunity to develop business models and behavioral interventions to maximize consumers’ and businesses’ benefit. This paper uses a systematic review of unlawful file sharing research, and the Theory of Planned Behavior, to motivate a large-scale panel study in which initial determinants were used to predict subsequent behavior. A meta-analysis found Attitudes, Subjective Norms and Perceived Behavioral Control were all associated with unlawful file sharing. Media type and demographic differences in the importance of Perceived Behavioral Control were found and attributed to more accurate evaluation of familiar activities, i.e., greater experience increases the influence of Perceived Behavioral Control but age does not. The panel study confirmed that greater past experience was associated with Perceived Behavioral Control and Intention. We conclude that past experience increases the efficacy of the Theory of Planned Behavior and specifically Perceived Behavioral control in predicting behavior, contrary to some widely held beliefs about the role of experience. The role of experience is therefore crucial to understanding people’s choices. Practically, improving social approval, positive evaluation and access to lawful media should reduce unlawful behavior

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
