Abstract. The aim of this paper is to provide a critical review of the literature on the econometric analyses of firm-level determinants to eco-innovation. The review reveals some gaps in knowledge. First, an integrated theoretical framework which merges the insights from different approaches is missing. Second, the influence of some variables is still unsettled (demand-pull and cost-savings), whereas others have hardly been included in previous analyses (internal and international factors).

Abstract. The deep economic crisis and the sharp rise in electricity prices have reduced electricity demand by Spanish households. This paper aims to analyse the responsiveness of household electricity demand and the welfare effects related to both factors in the 2006–2012 period by applying a demand model estimated with the quantile regression method.

Abstract. One of the main criteria to assess the success of instruments to support electricity from renewable energy sources (RES-E) is cost-effectiveness. However, a consensus on the definition of cost-effectiveness does not yet exist in the literature.

Abstract. There has been an intense debate on the quantification of the employment effects of renewable electricity deployment in the European Union. However, most studies carried out in the past have focused on specific countries and those with a European-wide scope have not provided disaggregated results per country. Furthermore, differences between importing and exporting countries have not been considered. This paper aims to cover those gaps.

Abstract. This paper analyses the determinants of household electricity demand with a panel data, partial adjustment model of the Spanish regions between 1998 and 2009. We find that electricity demand is positively and significantly related to several variables (electricity demand in the previous year, income, temperature range, penetration of electric water heating in households and the number of heating and cooling degree days).

Abstract. The aim of this paper is to review the combinations of RES-E support instruments in the European Union (EU), using different sources of data. It is shown that combinations are indeed a widespread phenomenon in the EU Member States.

Abstract. The effectiveness and cost-effectiveness of two main types of instruments (feed-in tariffs and quotas with tradable green certificates) have usually been compared in the literature on renewable electricity promotion. Due to negative past experiences with a third instrument (auctions), this instrument has been broadly dismissed in academics and, until recently, also in policy practice.

Abstract. Policy combinations and interactions have received a considerable attention in the climate and energy policy realm. However, virtually no attention has been paid to the analysis of the combination of different deployment instruments for the same renewable energy technology.

Abstract. The cost-effectiveness of support for renewable electricity is a main criterion to assess the success of policy instruments, together with effectiveness. The costs of support are also a source of significant concern for governments all over the world. However, significant confusion exists in the literature on the cost-effectiveness of public support for renewable electricity.

Abstract. The aim of this paper is to identify the factors that drive support levels for wind on-shore electricity in the Member States of the European Union (EU) with the help of econometric techniques. The econometric analysis is based on cross-section linear regressions with ordinary least squares. Four alternative specifications of the model have been estimated. The estimates comply with the basic hypotheses of the lineal model, i.e., absence of multicollinearity, accurate functional form, homokedasticity and normality in the distribution of errors.
