This paper addresses the economic and environmental effects of three scenarios of change for the electricity sector in Spain, in line with the European Union targets: (1) to address the low trade with the rest of Europe, increasing the integration with the European network; (2) to enhance environmental sustainability, increasing the use of renewable energy sources, while decreasing the use of brown energy sources; and (3) increasing the competitiveness of the Spanish electricity sector. To this end, we develop a computable general equilibrium model, with 72 productive sectors, eleven of which are energy sectors, where electricity is disaggregated into five production technologies and transmission, distribution, commercialization, and related activities. The model is calibrated on a previously developed input-output table with this detailed disaggregation for Spain for 2013. Our results suggest potential improvements in production and trade, and reductions in CO 2 emissions in scenario 2 are also observed. • We address the effects of three policy scenarios for electricity sector in Spain. • We analyze the effects of increasing trade, renewables, and competitiveness. • We construct and disaggregate a computable general equilibrium (CGE) model. • CGE distinguishes the businesses of the sector and the production technologies. • We found improvements in production and trade and reductions in CO 2 emissions.

This paper focuses on analysis of public opinion towards European integration in Greece, Portugal and Spain, countries known for their positive attitudes toward integration. In particular, the article analyses how public attitudes towards Europe have been formed in these countries. Secondly, it examines the determining factors of citizens' positive attitudes toward integration and shows the types of variables that are essential to understanding the differences between Greeks, Spaniards and the Portuguese. It also examines traditional euro-optimism in these southern countries. The findings show the relevance of identity and the various impacts of party platforms and ideology in attitudes of support for European integration. [ABSTRACT FROM AUTHOR]
