The contribution of this paper is to show that a simple nonlinear tax can achieve a long-run socially optimal level of pollution without the regulator knowing marginal abatement costs. Firms are charged their differential contribution to total damages, evaluated at the upper margin of current...

Policy discussions on global warming are focused on mitigation and adaptation. Here the role of ex post compensation as a substitute for ex ante mitigation is considered. In a simple 2-period model the salient features of the global warming problem suggest mitigation is difficult to motivate. A...

This paper argues that policies based on economic instruments are preferable to command and control approaches for effectively protecting biological diversity. This is due to sources of inefficiencies because of informational asymmetries between the regulator and private land users. We propose a...

Regulations (such as pollution standards) are frequently expressed as a uniform ratio between a target variable and a base variable. The efficient form of such regulations is firm-specific. When firms are very different in size, large firms typically should face a relatively more stringent...

Annual global CO2 emission forecasts at 2100 span 10 to 40 billion tonnes. Modeling work over the past decade has not narrowed this range nor provided much guidance about probabilities. We examine the time-series properties of historical per capita CO2 emissions and conclude that per capita...

The Stern Review, described as the most comprehensive review ever carried out on the economics of climate change, was published on 30 October 2006. The twin papers from a combined team of scientists and economists present a critique in two parts of the Stern Review. Part I focuses on scientific...

This paper applies principal component analysis to investigate the linkages, or dominant co-fluctuation patterns, of per capita carbon dioxide emissions across countries for the time period 1950–2000. Energy resource world markets are investigated as an offsetting mechanism possibly...
