In the early 1990s the Swedish economy experienced a severe economic and financial crisis which resulted in a substantial GDP decrease. Even though the crisis was not a complete surprise for many economists, almost no one expected that the Swedish economy would be prospering with booming productivity growth only a few years later. Economists have presented three explanations for the fast recovery and productivity growth in 1995–2006: market reforms, crisis recovery, and the impact of ICT. This paper offers an alternative view, emphasizing instead firms' substantial investment in intangible assets such as R&D, design, and advertising. Based on the growth accounting framework, intangible capital accounted for more than 30 percent of the labor productivity growth in the Swedish business sector from 1995 to 2006. Thus, Swedish TFP growth, one of the highest among OECD countries, is reduced substantially when investment in intangibles is included in the growth accounting analysis.

Abstract We analyze the effect of ICT and R&D on total factor productivity (TFP) growth across different industries in Sweden. R&D alone is significantly associated with contemporaneous TFP growth, thus exhibiting spillover effects. Although there is no significant short-run association between ICT and TFP, we find a positive association with a lag of seven to eight years. Thus, spillovers from R&D affect TFP much faster than spillovers from ICTinvestments. We also divide ICT capital into hardware and software capital. To our knowledge, this distinction has not been made in any previous study analyzing TFP at the industry level. The results show that lagged hardware capital services growth is significantly associated with TFP growth. Hence, investments complementary to hardware are needed to reap the long-run TFP effects from reorganizing production. Terms of use: Documents in EconStor mayJEL Codes: L16, O33, O47.

Terms of use: Documents in Forthcoming in: Research in Economic HistoryAbstract:This study consists of an examination of productivity growth following three major technological breakthroughs: the steam power revolution, electrification and the ICT revolution. The distinction between sectors producing and sectors using the new technology is emphasized. A major finding for all breakthroughs is that there is a long lag from the time of the original invention until a substantial increase in the rate of productivity growth can be observed. There is also strong evidence of rapid price decreases for steam engines, electricity, electric motors and ICT products. However, there is no persuasive direct evidence that the steam engine producing industry and electric machinery had particularly high productivity growth rates. For the ICT revolution the highest productivity growth rates are found in the ICT-producing industries. We suggest that one explanation could be that hedonic price indexes are not used for the steam engine and the electric motor. Still, it is likely that the rate of technological development has been much more rapid during the ICT revolution compared to any of the previous breakthroughs.

We investigate to what extent ICT and R&D capital is associated with value added growth in the Swedish business sector. By estimating output elasticities based on data for 47 different industries for the period 1993-2012 we show that ICT and R&D capital are significantly associated with value added for most specifications. We also divide ICT capital into hardware and software capital. To our knowledge, this distinction has not been made in any previous study at the industry level. In this case only the estimated elasticity of software is significantly different from zero. Finally, we use the growth accounting framework to compare the contribution from ICT and R&D to value added growth when output elasticities are based on either income shares or weighted least squares (WLS) estimates. The contribution of ICT to value added growth increases from 0.9 to 1.5 percentage points when WLS estimates are used instead of income shares.

Since the beginning of the 21 st century mobile broadband has diffused very rapidly in many countries around the world. This paper investigates to what extent the diffusion of mobile broadband has impacted economic development in terms of GDP. The results show that there is a significant effect from mobile broadband on GDP both when mobile broadband is first introduced and gradually as mobile broadband diffuses throughout different economies. Based on a two stage model we are able to conclude that on average a 10 percent increase of mobile broadband adoption causes a 0.6-2.8 percent increase in economic growth depending on the model specifications.
