This paper extends the methodology first proposed by Ahmad and Stern for the design of tax reforms that are optimal at the margin. The extension centers on a sharper approximation of welfare measures. The original approach and its variant are illustrated in the case of the current Mexican tax...

The combined use of specific and ad valorem taxation as a policy response to the welfare losses caused by international oligopoly is explored. With Nash competition between countries, taxation is inferior to quantity control. In contrast, when countries cooperate production control and taxation...

Standard economic analysis assumes the sets of public and private goods to be exogenously given. Yet societies very often choose the public-private mix, using resources to convert seemingly private goods into ones with public goods characteristics and vice versa. In practice, we see a...

This paper compares the technical efficiency of Brazilian public and private companies in water supply. To measure efficiency a stochastic production frontier model is estimated using two competitive distributions for the inefficiency error component: truncated normal and exponential. The...

This note considers the provision of incentives in public organizations that face the following three constraints. First, no lateral entry is possible. Second, the outside opportunities of bureaucrats are independent of their performance. Third, the organization cannot design incentive schemes...
