Sammanfattning

The purpose of this paper is to establish if Marshallian and Jacobian knowledge spillovers affect job creation in the green energy sector. Whether these two effects exist is important for the number of jobs created in related fields and jobs pushed away in other sectors. In the analysis, the production efficiency, in terms of jobs and job spillovers, from inventions in solar, wind and energy efficiency, is explored through data envelopment analysis (DEA), based on the Malmquist productivity index, and tobit regression. A panel dataset of American and European firms over the period of 2002–2017 is used. The contribution to the literature is to show the role of the spillovers from the same technology sector (Marshallian externalities), and of the spillovers from more diversified activity (Jacobian externalities). Since previous empirical evidence concerning the innovation effects on the production efficiency is yet weak, the paper attempts to bridge this gap. The empirical findings suggest negative Marshallian externalities, while Jacobian externalities have no statistical impact on the job creation process. The findings are of strategic importance for governments who are developing industrial strategies for renewable energy.

Sammanfattning

This chapter investigates Chinese wind power development and concludes that innovation cannot be pushed by the efforts of many, and that when the state clarifies directions and objectives, these can be achieved but with severe and unexpected side effects. Two topics are explored: wind curtailment and low technological development, both examples of unproductive entrepreneurship induced by government policies. The goal of wind power capacity expansion leads to construction (i.e., generation capacity) but little electricity. Examples of failures include low grid connectivity with, some years averaging 15% of generation capacity broken or unconnected to the grid. A key lesson for Europe is that forced innovation often amounts to little and that the old saying holds up: “no plan survives contact with reality.”

Sammanfattning

The purpose of this paper is to provide an analysis of the existence and possible direction of international knowledge spillovers in the solar energy sector. Specifically, the paper investigates how the accumulation of solar energy patents and public R&D spending affected the output of domestic granted solar energy patents. The econometric analysis relies on a data set consisting of most of the OECD countries plus China and analyzes two time periods; from 1990 to 2014 and the years 2000 to 2014. To analyze the data material, a Poisson fixed-effects estimator based on the Hausman, Hall and Griliches (1984) method was used. The empirical findings suggest that the domestic accumulation of patents and R&D is important for the potential development of new ones. Indeed, early investment in specific technology can be an indicator of future leadership in that field.

Sammanfattning

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.
