This paper investigates the association between relative mobile broadband penetration and carbon dioxide (CO2) emissions globally. The study is based on 181 countries for the period 2002-2020. The results indicate an initial increase in CO2 emissions for a country at an average emission level once mobile broadband is introduced. Possible explanations might be initial investment in network infrastructure and increased consumption of electricity. However, on average for the period 2002-2020 the continuous relationship between mobile broadband (defined as speeds of at least 256 kbps) and CO2 is significantly negative, i.e. emissions at a country level significantly reduce as mobile broadband penetration increase. Based on a two-stage model and controlling for fixed broadband and four addition control variables (i.e. population density, electricity consumption from fossil fuel, industry as a share of GDP and a regulation index), we are able to conclude that on average a 10 percentage points increase in mobile broadband penetration causes a 7 percent reduction of CO2 emissions per capita (given that the instrumental variable strategy, as assumed, identifies causal effects). Thus, the results show that investments in mobile infrastructure over longer periods of time can contribute to mitigating climate change.

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 mid-1990s value added has grown faster in the Swedish business sector than in the business sector of most other OECD countries. We investigate the association between ICT and R&D capital and value added in the Swedish non-farm business sector. By estimating neoclassical production function models 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. When controlling for economic shocks the results show that on average, if ICT capital increases by 10 percent, value added increases by 1.8 percent. 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. One possible explanation could be that all industries invest in hardware, but only the ones that successfully invest in and implement software enjoy positive effects from ICT.

The Swedish economy has developed rapidly since the mid-1990s relative to most comparable countries, in particular relative to almost all other EU-15 countries. We investigate two policy areas that are believed to have been important for the strong economic development in Sweden during the last two decades, namely product market reforms and incentives to innovate. The paper provides a short description of the policy changes that have taken place within these areas since the early 1990s and offers ideas for additional policy reforms that would pave the way for continued successful economic development.

Since the mid 1990s labor productivity growth in Sweden has been high compared to Japan, the US and the western EU-countries. While productivity growth has been rapid in manufacturing, it has been much slower in the service sector. Paradoxically, all employment growth since the mid 1990s has been created in business services. The two traditional explanations of this pattern are Baumol’s disease and outsourcing. This paper puts forward an additional explanation, based on the observation that manufacturing industries have invested heavily in intangible assets such as R&D and vocational training. In 2005–2006, intangible investment was 25 percent of value added in manufacturing, while the corresponding figure for the service sector was 11 percent. Moreover, calculations based on the growth accounting framework at the industry level in 2000–2006 show that intangible investment accounted for almost 30 percent of labor productivity growth in manufacturing. Thus, investments in intangibles that mostly are knowledge intensive services have contributed considerable to productivity growth in Swedish manufacturing since 1995.

In this paper I attempt to replicate for Sweden the Corrado, Hulten and Sichel (2006) and Marrano and Haskel (2006) working papers on spending on intangible assets in the US and the UK. Based on their measurement methods the total spending on intangibles in Sweden in 2004 was 277 billion SEK or 10.6 percent of total GDP. Based on total spending it can be estimated that total investment in intangibles was 227 billion or approximately two-thirds of the total investment in fixed capital in 2004. Thus, investment in intangibles was considerable in 2004. The corresponding figures for the UK and the US were 10.9 and 13.1 percent, respectively. Even though the measurement methods of intangibles must be further developed, it could be argued that intangibles in the future should be included in the Swedish national accounts.

Rapid price decreases for ICT-products in the 1990s have been largely attributed to the introduction of hedonic price indexes. Would hedonic price indexing also have large effects on measured price and productivity during other technological breakthroughs? This paper investigates the impact of hedonic and matched model methods on historical data for electric motors in Sweden 1900–35. The results show that during the productivity boom of the 1920s, the constant prices for electric motors decreased by 9.7 and 8.1 percent per year depending on whether hedonic or matched model price indexes were used. This indicates high productivity growth in the industry producing electric motors 1920–29. In contrast to Sweden, the US annual total factor productivity was only, according to current best estimates, 3.5 percent in Electric machinery compared to 5.3 percent in manufacturing 1920–29. However, hedonic price indexes were not used to calculate US productivity. Moreover, in comparison to the matched model, the hedonic price index on average overestimates price decreases when prices are decreasing and overestimates price increases when prices are increasing. However, the total effect of the two different price indexes remains approximately the same in 1900–35. Finally, it is shown that the price decreases for electric motors in the 1920s are not in par with the price decreases for ICT-equipment in the 1990s, even if hedonic indexing is used.

This paper investigates labor productivity growth and the contribution to labor productivity growth in Swedish manufacturing during electrification and the ICT revolution. The paper distinguishes between technology-producing, intensive and less intensive technology-using industries during these technological breakthroughs. The results show that labor productivity growth and the overall contribution to labor productivity growth was considerably higher in technology-producing industries following the ICT revolution. Moreover, the results presented here show no evidence that industries that were early adopters of electric motors and ICT, on average would have contributed more to productivity growth in Swedish manufacturing.

Rapid price decreases for ICT-products in the 1990s have been largely attributed to the introduction of hedonic price indexes. Would hedonic price indexing also have large effects on measured price and productivity during earlier technological breakthroughs? This paper investigates the impact of hedonic and matched model methods on historical data for electric motors in Sweden 1900–35. The results show that during the productivity boom of the 1920s, current prices for electric motors decreased by 13.2 and 12.2 percent per year depending on whether hedonic or matched model price indexes were used. This indicates high productivity growth in the industry producing electric motors in 1920–29. In contrast to Sweden, the US annual total factor productivity growth was only, according to current best estimates, 3.5 percent in Electric machinery compared to 5.3 percent in manufacturing in 1920–29. However, hedonic price indexes were not used to calculate US productivity. Finally, it is shown that the price decreases for electric motors in the 1920s were not on par with the price decreases for ICT-equipment in the 1990s, even if hedonic indexing is used in both cases.

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.

This paper investigates the relative labor productivity level for total manufacturing in Germany, Sweden and the US for the period 1980-2001. The paper also presents estimates of labor productivity levels for 18 different manufacturing industries for the period 1993-2000. The results show that the Swedish manufacturing productivity caught up with German and US productivity in the 1990s, overtaking the German level in 1995 and coming very close to the US level by the end of the 1990s. It has been argued that much of the Swedish surge in labor productivity during the second half of the 1990s was due to the spectacular growth of the Radio, television and communication equipment (RTC) (ISIC 32) industry. However, this paper shows that since 1998 Swedish RTC productivity has been declining relative to the corresponding industry in Germany and the US. Moreover, it is shown that the productivity growth of the ICT-producing industries is very sensitive to the value added price deflators used to calculate real value added growth rates. It is also shown that intermediate input prices have a large impact on the measured real value added growth for the Swedish Radio, television and communication equipment industry. It is argued that the accuracy of the price statistics for intermediate inputs is very uncertain for the Swedish Radio, television and communication equipment industry. Therefore estimates based on the US intermediate input price deflators suggest that the productivity growth of the Swedish Radio, television and communication equipment industry during the 1990s is partly a statistical artefact. This implies that the productivity growth of total manufacturing also has been overestimated.

I boken Bortom dot.com-företagen sammanfattar Robert E. Litan och Alice Rivlin resultaten från en utvärdering som gjorts av Brookingsinstitutet. I denna slås det fast att Internet kommer att möjliggöra en 0,25 till 0,5 procentenheter högre produktivitetstillväxt per år i den amerikanska ekonomin de kommande fem åren. I denna uppsats analyserar vi huruvida Europas länder också kommer att kunna få en liknande utveckling. Fokus ligger på en analys av hur investeringar i informations- och kommunikationsteknologi (IKT) inverkar på produktivitetstillväxten. Vidare presenteras resultat från produktivitetsberäkningar på branschnivå inom tillverkningsindustrin för Finland, Frankrike, Sverige, Tyskland och USA. Resultaten visar att större delen av produktivitetstillväxten under 1990-talet i dessa fem länder har skett i de IKT-producerande branscherna, medan mycket lite tyder på att det skett någon större spridning till IKT-användande branscher inom tillverkningsindustrin. Däremot tyder USAs höga aggregerade produktivitetstillväxt på att branscher utanför tillverkningsindustrin svarat för avsevärda produktivitetsökningar. Resultaten visar också att teleproduktindustrins fenomenala tillväxt varit helt avgörande för Sveriges och Finlands kraftfulla industriella uppsving under 1990-talet. Litan och Rivlin drar slutsatsen att spelreglerna i den amerikanska ekonomin möjliggör en snabb framtida produktivitetsutveckling. Vi menar dock att det finns en risk att produktivitetsutvecklingen i Sverige och de flesta andra EU-länder kan förväntas bli lägre än i USA så länge viktiga branscher så som parti- och detaljhandel, sjukvård och byggsektorn saknar fungerande konkurrens.
