Fenner School Seminar: 12th November

I'm giving a seminar at the Fenner School on November 12th. It will be an expanded version of the presentation I'm giving at ANZSEE in Darwin. Here is the abstract:

Modelling Global Trends in Energy Efficiency

This seminar reports on ongoing research in the CERF Environmental Economics Research Hub funded project: “Modelling the Global Diffusion of Energy Efficiency and Low-Carbon Technology”. The environmental Kuznets curve has been a popular simple model of the relationship between economic growth and environmental quality. It is plagued, however, by significant econometric issues and explains relatively little about the differences in emissions between countries. The between estimator is a simple consistent estimator of long-run coefficients in panel data that avoids these issues and performs well in real world situations. I apply the between estimator to both environmental Kuznets curves for carbon and sulfur emissions and a more sophisticated production frontier model of energy efficiency. The latter model explains differences in energy efficiency across countries in terms of differences in input and output mix, climate, and differences in the level of energy efficiency technology. The residuals from this model are the underlying trends in energy efficiency technology in each country. In the final part of the presentation I will show how a social choice model can be used to explain differences in environmental technology across countries.
