Abstract

This paper aims to analyse how the European Union (EU) energy policy has merged social policy concepts with energy efficiency policy. Energy efficiency has increasingly become understood through social policy concepts such as energy poverty, energy inequality, and lack of cohesion. Previous research has shown how the social aspects of energy efficiency have been highlighted by the European Commission when discussing the multiple benefits of increased energy efficiency efforts, such as building renovations.

Using a mixed-method approach with material from the European Commission, the Council of the European Union, and the European Parliament, we review energy policy from a social policy perspective. The analysis is conducted in two steps. First, we identify which EU institutions acted as agenda-setters in introducing the social aspects of energy efficiency. Second, we describe and analyse the framing process through which social concepts are merged with energy policy.

The study combines qualitative and quantitative analyses of EU policy documents. A set of key words is used in the quantitative analysis to explore the links between social policy and energy policy.

We conclude that social aspects were first connected to the energy policy field by the European Parliament. This connection was later reinforced by the European Commission through the inclusion of social policy elements, particularly in policies addressing the transition to energy efficiency and zero-carbon buildings, where concepts such as energy poverty have become central.

Abstract

This study investigates the relationship between the urban wage premium and employer concentration using Swedish full population employer-employee data. Departing from an AKM modeling framework to distinguish worker from firm specific heterogeneity – a measure of rent-sharing – we then measure the urban wage premium using differences in the estimated firm fixed effects at the level of local industries, nested within local labor markets. Our results suggest that labor market employer concentration, as calculated using the Hirschman-Herfindahl index and a leave-one-out instrumental variable design, can account for a significant share of the estimated urban wage premium (UWP). Addressing city-level wage income inequality by applying our model to different segments of the local labor market income distribution, we find that while the UWP pertains to all income segments, it is largest for top-income levels (above the 90th percentile), and within this segment employer concentration also has the largest explanatory power. Thus, while being an important explanatory factor for all percentiles of the local income distribution, a relatively lower employer concentration within larger cities, and vice versa, higher concentration within smaller cities, primarily help explain the variance of top wages within these cities/labor markets.

Ratio Working Paper No. 374: The Impact of High-Skilled Migration on Productivity in Swedish Firms

Abstract

The migration of highly skilled labor has received increasing attention due to its role in fostering innovation and productivity. This study explores the impact of foreign experts on the productivity of Swedish companies. Utilizing a difference-in-difference model with comprehensive register data from 1996 to 2015, the analysis reveals that Swedish companies hiring foreign experts experience a significant productivity increase of 6 to 11 percent within two to three years post-hiring. This effect is particularly pronounced in small and medium-sized enterprises and is slightly enhanced when excluding returning Swedish-born experts. Additionally, the study finds that both labor and capital productivity rise, along with a modest increase in wage incomes for other employees, estimated at 1.5 to 2 percent. However, the wage effects are less robust compared to productivity impacts. The findings underscore the importance of attracting foreign talent to bolster productivity. This research fills a crucial gap in the literature by focusing on the specific effects of foreign experts on total factor productivity in a small, knowledge-oriented economy like Sweden’s.
