In this paper, the questions of how support policies affect invention and diffusion of solar PV technology and whether the effect is heterogeneous and counteracting are investigated in order to help policy makers produce a better policy mix. The policies (and policy proxies) investigated are Feed-in-tariffs (FITs), Public R&D stock and flow, Environmental tax, and Environmental Policy Stringency Index. The policies are within the control of national government and no EU level policies are investigated. Evaluating policies on several dimensions is highly important since there is a risk that policies can promote one aspect of technological progress such as invention but derail diffusion. A Schumpeterian technological development approach is utilised on a panel dataset covering 23 European countries between 2000 and 2019. Two econometric approaches are employed, a negative binomial regression model is used to assess inventions and a panel data fixed effect regression is used for the diffusion model. The empirical findings suggest that no counteracting policy effects were present.

China is currently the world’s largest installer of wind power. However, with twice the installed wind capacity compared to the United States in 2015, the Chinese produce less power. The question is: Why is this the case? This article shows that Chinese grid connectivity is low, Chinese firms have few international patents, and that export is low even though production capacity far exceeds domestic production needs. Using the tools of Austrian economics, China’s wind power development from 1980 to 2016 is documented and analyzed from three angles: (a) planning and knowledge problems, (b) unproductive entrepreneurship, and (c) bureaucracy and government policy. From a theoretical standpoint, both a planning problem and an entrepreneurial problem are evident where governmental policies create misallocation of resources and a hampering of technological development.

Går det att förena ekonomisk tillväxt med hållbar
utveckling? Den här boken beskriver hur miljöskadliga utsläpp och användningen av naturresurser i
Sverige har förändrats över tid.
Sedan 1990 har Sveriges befolkning ökat med drygt
1,6 miljoner och ekonomin nästan fördubblats. Samtidigt har koldioxidutsläppen minskat med 27 procent mellan åren 1990 och 2018, konsumtionen av
el, vatten och energi har stått still vilket innebär att
ekonomin är nästan dubbelt så effektiv. Av de 26
luftföroreningar Naturvårdsverket mätt sedan 1990
har 24 gått ner fram till 2017. I många fall har det
skett mer än en halvering.

Ratio Working Paper


The empirical evidence concerning the job-creation impact of wind power technology through knowledge spillovers is yet poor. Our objective is to contribute to the literature and bridge this gap. Specifically, our analysis explores to what extent investments in innovation activities of one firm affect the neighbouring firms’ generation of knowledge spillovers in the same sector (intra-industry) or to different sectors (inter-industry) and how this complex knowledge diffusion process impacts the employment dynamics. The econometric analysis relies on a sector-based panel dataset for the USA, Europe, and Japan between 2002 and 2017. The empirical findings suggest that there were negative employment spillovers from the same technology sector (Marshallian externalities) while the spillovers from more diversified activity (Jacobian externalities) have a positive impact on job-creation. The findings have relevant policy implications for governments who are developing an industrial strategy for wind power technology.
