As a consequence of changes in energy prices and new environmental policies, a wealth of historical experience has accumulated over the past two decades. Interpreted within the framework of the neoclassical theory of economic growth, this experience provides essential guidelines for future policy formation. Volume 2: Energy, the Environment, and Economic Growth presents a new econometric general equilibrium model of the United States that captures the dynamic mechanisms underlying growth trends and responses to energy and environmental policies. Jorgenson uses the model to analyze the impacts of environmental regulations on US economic growth and tax policies for controlling U.S. emissions of carbon dioxide.
