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.

Abstract. This paper analyses the emergence of public sector international joint laboratories as an increasingly important new phenomenon in the internationalisation of public sector research. Using a survey and interview-based qualitative methodology, it explores the trends in the establishment of such laboratories, the aims for which they are established and the extent to which these aims are met. We find a considerable degree of organisational diversity among them in terms of size, structure, resources and legal status.

Abstract. We estimate the effects of highways on the suburbanization of Spanish cities.

Abstract. Investment in transport infrastructure reduces the cost of distance and enables firms to establish contacts over larger distances. Using data from a panel of Spanish manufacturing firms and geographic information system techniques, this article studies the impact of domestic transport cost reductions on firms’ export market participation, taking into account the role of entry costs and other firm characteristics.

Abstract. This paper analyzes the main determinants influencing environmental innovators (i.e. firms developing or adopting environmental innovations) in Spain with respect to non-environmental innovators. Similarly to other contributions in the literature, our results show that Spanish environmental innovators respond to regulatory stimulus in the form of demand-pull and technology-push instruments. They have a high internal technological capability and combine internal and external information sources, mostly in cooperation with knowledge institutions.

Abstract. Policies increasingly come in complex packages and understanding the nature of design criteria for such portfolios is increasingly important. However, existing studies of policy mixes fail to carefully define the dependent variable of the inquiry. As a result, theorization of policy design has lagged, the cumulative impact of empirical studies has not been great and understanding of the phenomena, despite many observations of its significance in policy studies, has not improved significantly over the past three decades.
