Economic Theory and Global Warming

Professor Uzawa constructs a theoretical framework in which three major problems concerning global warming and other environmental hazards may effectively be addressed. First, all phenomena involved with global environmental issues exhibit externalities of one kind or another. Secondly, global environmental issues involve international and intergenerational equity and justice. Thirdly, global environmental issues concern the management of the atmosphere, the oceans, water, soil, and other natural resources that have to be decided by a consensus of all affected countries.
