Conventional wisdom argues that environmental policy is less costly if environmental policy induces the development of cleaner technologies. In contrast to this argument, we show that the cost of environmental policy (a reduction in emissions) may be larger with induced technical change than...

We analyze the efficiency of urbanization patterns in a stylized dynamic model of urban growth with three sectors of production. Pollution, as a force that discourages agglomeration, is caused by domestic production. We show that cities are too large and too few in number in uncoordinated...

While fossil energy dependency has declined and energy supply has grown in the postwar world economy, future resource scarcity could cast its shadow on world economic growth soon if energy markets are forward looking. We develop an endogenous growth model that reconciles the current aggregate...

Unintended consequences of a pre-announced climate policy have been studied in a variety of situations. We show that early announcement of a carbon tax gives rise to a “Green-Paradox,” in that it increases polluting emissions in the interim period (between announcement and actual...
