This paper analyzes tax-policy measures within a two-sector endogenous
ly-growing economy with elastic labor supply. Pollution is either mode
led as a side product of physical capital used as a production factor
in the find-good sector or as a side product of production. The framew
ork allows us to analyze the consequences of isolated tax changes or o
f a revenue-neutral environmental tax reform for economic growth. Alth
ough pollution does not directly affect production processes, it can b
e shown that a higher pollution tax as well as a revenue-neutral envir
onmental tax reform boost economic growth, whereas a tax on capital, c
onsumption, or labor reduces the long-term growth rate of the economy.
