"Intra-EU knowledge flows in the renewable energy sector : A patent citation analysis"

Maria Luisa Mancusi (Catholic University Milan and CRIOS, Bocconi University) joint with Chiara Conti, Francesca Sanna-Randaccio, Roberta Sestini and Elena Verdolini

Abstract :

We test whether demand-pull environmental measures, introduced with the 1997 Commission White Paper and following Directives, had an impact on the fragmentation of EU research and innovation effort in the strategic field of renewable energy. By focusing on knowledge spillovers, we study the pattern and evolution of knowledge flows within the EU and between the EU and two frontier innovators : the United States and Japan. This research question is motivated by increased concern that the fragmentation of EU renewable energy research and innovation systems may hamper the ability to address climate challenges at socially acceptable costs. Following a well-established tradition, we measure the intensity and the direction of knowledge flows by looking at patent citations. Our results suggest that after 1997 Member States’ national innovation systems have evolved towards a more integrated innovation space at the EU level. Furthermore, environmental policies seem to have pushed the EU to become a frontier innovator, since the EU15’s role as a source of knowledge for the US increased. However, innovative activity at EU level is still poorly integrated if compared to the American and Japanese systems.

"Evaluating the trade-off between hydropower revenues and ecosystem integrity : a case study in Southern France"

Anna Cretì (U. Paris Dauphine Leda-CGEMP and Ecole Polytechnique) joint with Marc Joëts and Federico Pontoni

Abstract :

In the coming years, France will renew hydroelectric concessions through beauty contests. Bidders will present offers for technical and environmental improvements, as well as a revenue sharing percentage for local authorities. This framework generates a potential trade-off between revenue sharing and environmental improvement, which we have investigated in this paper using a discrete choice experiment (DCE). The experiment has been conducted on a representative sample living in the Aspe valley, one catchment where concessions are active for a total of almost 100 MW. Our DCE is innovative because we package the revenue sharing as an immediate rebate on electricity bills while maintaining a willingness to pay (WTP) approach. Respondents could choose between higher rebates with lower ecosystem improvements or lower (or no) rebate with higher ecosystem improvements. From a methodological standpoint, we use (i) the standard approach to preference space, in which distributions of the coefficients are estimated and WTP is derived from the ratio of two coefficients ; and (ii) the WTP space approach, in which we specify the distribution of WTP directly at the estimation stage. According to the experiment results, the highest compensating surplus is above € 1,225 per household per year. Individual marginal WTP for a satisfactory fish stock reaches 277 €/year, which is three times the maximum rebate offered. Finally, all environmental attributes are significant and worth a monetary effort. We then argue that hydroelectric concession bidders should give clear priority to environmental factors.
