Do Higher Electricity Prices Induce Innovation? An Empirical Analysis

Sammanfattning

Green innovation is an important part of combating climate change, and therefore, it is importantto examine what stimulates innovation, especially in innovation-forward countries, such as Sweden.Sweden’s electricity pricing system is also interesting to study. This thesis has examined the effectof electricity prices on both total R&D expenditure and the probability that firms invest in energyor CO2-reducing innovation in Sweden. To study the probability of if a firm invests in energy- orCO2-reducing innovation, a logit random-effects is used. To study the effect of electricity priceson total R&D expenditure, a fractional fixed effects logit model is used. The results indicate that,in the short run, electricity prices have no significant effect on whether firms invest in energy- orCO2-reducing innovation in Sweden. However, the results are not robust. Furthermore, the previousyear’s electricity price is found to affect on a firm’s total R&D expenditure in the next year in Sweden.The effects of electricity price on R&D expenditure are found to have some heterogeneous effectsand are sensitive to which electricity price measurement is used to study the relationship. While therelationship between electricity prices and innovation in Sweden would benefit from further studies,this thesis provides knowledge on the effect of electricity prices on induced innovation in Sweden,which has not previously been studied, as previous research has examined electricity prices andinnovation in China and Germany. 11Acknowledgments: First, I want to thank the Swedish Agency for Growth Analysis for the opportunity to write my thesis incollaboration with them.
