The purpose of this paper is to survey the theoretical literature on wealth transfer taxation. The focus is normative: we are looking at the design of an optimal tax structure from the standpoint of both equity and efficiency. The gist of this survey is that the optimal design closely depends on...

This paper incorporates tax evasion into the analysis of optimal linear income taxation. Tax evaders can influence the probability of being caught, if audited, through expenditures on concealment. It is proved that tax evasion can make a given tax system more as well as less progressive...

The authors introduce commodity taxation into a vertical differentiation model with endogenous product selection. They show that a uniform ad valorem tax lowers both qualities, distorts the allocation of consumers between firms, and lowers the consumer prices of both variants. A small uniform...

In many countries elderly workers are subject to a double distortion when they consider prolonging their activity: the payroll tax and a reduction in their pension rights. It is often argued that such a double burden would not be socially desirable. We consider a setting where it would be...

This paper studies the optimal linear pension scheme when society consists of rational and myopic individuals. Myopic individuals have, ex ante, a strong preference for the present even though, ex post, they would regret not to have saved enough. While rational and myopic persons share the same...

It is often argued that the observed trend towards early retirement is due mainly to the implicit tax imposed on continued activity of elderly workers. We study the relevance of such a distortion in a political economy model with endogenous age of retirement. The setting is a two-period...

We consider a repeated electoral competition game between two parties, each representing a constituent with a given income level. Parties are unable to commit to any policy before the election; they choose a non-linear income tax schedule once elected. In each period, citizens cast a vote either...

Postal regulators set price controls in order to simultaneously ensure the provision of the universal service, promote competition and equity. We study the associated price control procedures in a model where the universal service provider offers both a single piece product and a business mail...
