Mohammed Dore, a co-editor of this volume, did his doctoral studies at Oxford University. He is Professor of Economics at Brock University and has published three other books and a number of articles. His current research interests are global environmental change and its distributional consequences on the rich and the poor. He leads an Inter-American team of researchers from South, Central and North America on the role of forests in mitigating global warming. His research has been funded by the Social Sciences and Humanities Research Council of Canada, the National Science Foundation of the USA, the Inter American Institute of Global Change Research (which is now based in Brazil) and also the National Science Foundation of Brazil. He is also a member of NEPAMA, an international consortium of research, based at the University of Brasilia. Tim Mount received his PhD from the University of California, Berkeley (1970). His research and teaching interests are econometric modeling and policy analysis relating to the demand for fuels and electricity and to environmental policies. Currently, research is being conducted on the implications for long-run planning of incorporating the costs of environmental damage from emissions of sulfur dioxide, nitrogen oxides and carbon dioxide, and the selection of economically efficient strategies for meeting ozone standards and stabilizing emissions of greenhouse gases.
