Unlike previous analyses, we consider (i) that IT may affect productivity growth both directly and indirectly, through human capital interactions, and (ii) possible externalities in the use of IT. Examining, hypothetically, the statistical consequences of erroneously disregarding (i) and (ii) we...

Unlike previous analysis, we consider (i) possible externalities in the use of IT and (ii) IT and human capital interactions. Examining, hypothetically, the statistical consequences of erroneously disregarding (i) and (ii) we shed light on the small or negative growth effects found in early...

Investigating the robustness of the skill-biased technical change hypothesis, this analysis incorporates two novel features. First, effective labor is modeled as the product of a quantity measure - number of employees with a given level of education - and a quality index, depending on, i.a.,...

Register data are described, in general terms and in specific terms, focusing on informational content from an educational science perspective. Arguments are provided for why educational scientists can benefit from register data. It is concluded that register data contain lots of information...

In Europe, accounting standards prevent larger expenditures on employer-sponsored training from being treated as investments. Using Sweden as example, we discuss two consequences for training. First, the timing: training will be conducted when income is large enough for training costs to be...

A regression model is considered where earnings are explained by schooling and ability. It is assumed that schooling is measured with error and that there are no data on ability. Regressing earnings on observed schooling then yields an estimate of the return to schooling that is subject to...

Using a Difference-in-Differences approach we evaluate the effects of a 10 percentage points reduction in the payroll tax introduced in 2002 for firms in the northern part of Sweden. We find no employment effects for existing firms and can rule out that a 1 percentage point payroll tax reduction...
