The purpose of this paper is to clarify the answers given in a number of seminal public finance articles to the following questions :
a) What is a proportional tax structure and when is it optimal ?
b) What is the difference between the optimality conditions for optimal public sector pricing and for optimal taxation?
These issues were along with several others considered in three articles that appeared concomitantly: Lerner (1970), Baumol and Bradford (1970) and Dixit (1970), The articles were subsequently commented upon by Ng (1972), Bradford and Baumol (1972) and Sandmo (1974).
I wish to thank Torben M. Andersen, Tony Atkinson, Avinash Dixit, Agnar Sandmo and John Weymark for helpful comments on earlier drafts of this paper.
