Differential tax analysis

From Wikipedia, the free encyclopedia

Differential tax analysis is the analysis of the impact of different taxes, in different markets, as to achieve a given level of Government revenue. It is a branch of General equilibrium analysis, considering several different markets and the impact of a (usually) excise tax on each of them, as well as in associated markets (those of the inputs, substitutes and complements, for instance).

Most generally, the general equilibrium final results will differ little from those attained from a partial equilibrium analysis. This will not apply, however, if there are strong complementarities with markets other than the one which is being taxed.
