In this paper we show that corporate taxes are likely to have considerable
implications for rent-seeking activity. We find that corporate taxation ten
ds to significantly reduce rent-seeking, and that it favors rent-seeking by
established firms and discriminates against new and zero profit firms. Ind
eed, we show that corporate tax regulations may completely block rent-seeki
ng by new corporations, and that rent-seeking competitions may be character
ized by an equilibrium that features a small number of profitable and well
established firms. Tax regulations may therefore impart an oligopolistic te
ndency to rent-seeking markets. Moreover, our results may have significant
implications for the effects of corporate taxes on patent races, tournament
s, and other first-past-the-post competitions.
