I use a stochastic production frontier to model energy efficiency trends in 85 countries over a 37-year period. Differences in energy efficiency across countries are modeled as a stochastic function of explanatory variables and I estimate the model using the cross-section of time-averaged data,...

This study uses a stochastic production frontier to model trends in energy efficiency over time in a panel of 85 countries. No a priori structure is imposed on technological change over time though differences in the level of technology across countries are modeled as a stochastic function of...

The expansion in the supply of energy services over the last couple of centuries has reduced the apparent importance of energy in economic growth despite energy being an essential production input. We demonstrate this by developing a simple extension of the Solow growth model, which we use to...

The aim is to measure and understand the long-term factors behind trends in energy and carbon intensity in different economies and how improvements in energy efficiency diffuse globally. Of particular interest is the rate of diffusion from developed to developing countries and the factors that...

The aim of this study is to measure and understand the long-term factors behind trends in energy and carbon intensity in different economies. It also looks at how improvements in energy efficiency are spread to countries around the world. Of particular interest is the rate at which efficiency...

Households may imperfectly implement energy saving measures. This study identifies two factors resulting in imperfect use of energy-saving technology by households. First, households often continue to use old technologies alongside new ones, and, second, technologies have shorter actual...

The 2020 COVID-19 driven recession saw a sharp drop in carbon dioxide emissions as transportation and some other energy uses were curtailed. This was an unusual recession as it was driven by a pandemic. Previous research shows that when GDP declines carbon emissions fall faster relative to GDP...

There has been extensive analysis of the drivers of carbon dioxide emissions from fossil fuel combustion and cement production, which constituted only 55% of global greenhouse gas (GHG) emissions in 1970 and 65% in 2010. But there has been much less analysis of the drivers of greenhouse gases in...
