The Race for Polluting Permits
International markets for tradable emission permits (TEP) co-exist with national energy taxation. A firm trading emission permits in the international market also pays energy taxes in its host country, thus creating an interaction between the international TEP-market and national energy taxes. In this paper we model that interaction in a framework of a perfectly competitive international TEP-ma...
متن کاملNon-polluting Automobiles
The advantages/disadvantages of energy storage devices, which can provide nonpolluting automobile systems are discussed. Four types of storage devices are identified: electro-chemical (batteries) hydrogen electro-mechanical (flywheels) Molten salt heat storage A high speed flywheel with a small permanent magnet motor/generator has more advantages than any of the other systems and might become a...

متن کاملOptimal consumption of polluting and non-polluting goods: The role of habits
We present a basic exogenous growth model with two consumption goods that differ as regards their contributions to environmental pollution. Allowing for habit formation of the polluting good, we show under which conditions habit formation raises the consumption of the clean good relative to the dirty one in the competitive economy. Further, we demonstrate when habit formation generates a lower ...
متن کاملThe Environmental Performance of Polluting Plants: A Spatial Econometric Approach
This paper uses plant-level data from EPA and Census databases to incorporate spatial components in models of the environmental performance (compliance and emissions) of manufacturing plants. The spatial approaches include creating explanatory variables based on information related to the plant’s location and the location of nearby plants, testing for spatial autocorrelation in environmental pe...
