This paper analyzes the effects of specific and ad valorem taxation in an industry with downstream and upstream oligopoly. We find that in the short run, i.e. when the number of firms in both markets is exogenous, the results concerning tax incidence tend to be qualitatively similar to models...

To determine the full effects of taxation on income distribution, policymakers need to consider the impacts of tax evasion. In the standard analysis of tax evasion, all the benefits are assumed to accrue to tax evaders. But tax evasion has other impacts that determine its true effects. As...

It is often argued that the quantity which is traded on the market is independent of the side of the market which is taxed. However, this assertion need not hold, especially in imperfectly competitive markets like that for labour. Taking an efficiency wage economy as an example, it is shown that...

Since gasoline has a relatively inelastic demand, raising government revenue via gasoline taxes could appear appropriate as it entails a relatively small deadweight loss. However, gasoline retail is generally a highly concentrated market, hence the assumption of perfect competition when...

Recent theoretical work has shown that the incidence of ad valorem and specific taxes may differ and each may be over or under-shifted onto consumers in the presence of imperfect competition. These results are used to derive a method of estimating market power and conduct. An application is made...
