Abstract:
Given the intensifying debates on whether governments should promote particular renewable energy technologies, the main objective of this study is to investigate the long-and short-run effects of policy-induced expansion of renewable solar and wind technologies on economic growth and employment in 15 European Union (EU) member states during 1990-2013 by using panel-data time-series econometric techniques. Instead of relying on renewable energy consumption or generation as commonly done in the literature, we focus on the capacity for solar and wind power generation, which is largely a consequence of the EU's renewable energy policies. In summary, we find that, to date, renewable energy policy-induced wind and solar power capacity promotes growth and/or employment in the short run, but these capacity increases do not stimulate economic growth in the long run in the EU-15 region. In fact, our results tend to support the opposite relationship: increases in wind and solar power capacity are associated with negative economic growth, at least at the total economy level.

Abstract:
In this study, using hourly data from a representative sample of Swedish households on standard tariffs, we investigate the welfare and emission implications of moving to a mandatory dynamic pricing scheme. We allow demand during different hours of a day to affect utility differently, and account for the derived nature of electricity demand by explicitly accounting for the services (end-use demands) that drive hourly electricity demand. We use the flexible Exact Affine Stone Index (EASI) demand system, which accommodates both observed and unobserved heterogeneity in preferences, to understand changes in load consequent to hourly retail pricing. Our findings suggest that, following hourly retail pricing, changes in load patterns across hours are relatively small: total load changes by less than one percent. There are correspondingly small reductions in welfare and carbon emissions, of less than 0.2 percent and 0.47 percent, respectively. Overall, in the context of a decentralized, competitive retail electricity market-setting, our results suggest that the benefits to ensuring that the retail price of electricity reflects the hourly marginal cost is small, at least in the short run.
