"Effects of Macroeconomic Policy on Air Quality: Evidence from the US," MPRA Paper 62001, University Library of Munich, Germany.

In the existing literature much attention has been given to the toolbox of regulatory policy instruments at the disposal of policy makers for addressing environmental concerns. Microeconomic treatment of environmental policy considers the optimal allocation of a given scale of resource flow within the economy, but neglects the scale and composition of economic activity relative to the ecosystem that supports it. An ecological approach to macroeconomics requires the appreciation of physical constraints to economic growth.
