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. Empirical comparison of the price effects of the two taxes is limited. There are no previous estimates...

We examine the effects of two different types of commodity taxation, specific and ad valorem, on wages and profits. We analyze two models of wage determination, one with efficiency wage setting and one with bargaining between a union and a firm. In the former, a (locally) revenue-neutral shift...

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...
