We present results from a study on the economic performances of a public mass transit firm. Measures of productive efficiency as well as of adequacy between supply and demand (effectiveness) are computed monthly. We observe a clear positive trend for technical performances but less favorable...

This paper characterizes the outcome of tax competition between autonomous fiscal authorities. It treats the case of a two-region economy, where an origin-based commodity tax is levied by each region on a private good to finance a local public good. A second private good is untaxed. We describe...

When environmental externalities are international - i.e. transfrontier - they most often are multilateral and embody public good characteristics. Improving upon inefficient laissez-faire equilibria requires voluntary cooperation for which the game-theoretic core concept provides optimal...

The goal of this study is to propose a method for determining the limits of the Brussels urban agglomeration. The method is inspired by a review of the criteria used by national statistical institutes in several countries and based on a limited set of simple and easily available statistical...
