The results data from my recent paper in Energy Economics are now up on my data page.
Data is presented in terms of distances and log distances relative to a stochastic frontier estimated with the between estimator for the 1971-2007 period. A distance of one (or log of zero) implies that a country is just on this frontier. But the frontier moves over time as world best practice improves. Countries can have time series values below zero (or a distance of less than one) because they may reach levels of energy efficiency greater than the the average best practice for the whole period. This is especially the case in the later years. The file also gives income per capita in PPP terms from the Penn World Table. Click here for more posts explaining this project.
