* This is a revised version of Chapter 1 of my Ph.D. Dissertation submitted to London
University. My supervisor O. Hart and M. Gonzalez-Maestre, C. Herrero, C. Mazdn, J. Moore, J.
Segura, D. Ulph, A. Villar, X. Vives and an anonymous referee provided useful comments. The usual
caveat applies. The Fundacion del I.N.L and D.G.I.C.Y.T., under projects PB88-0289 and PB91-0756,
provided financial support in an early stage of this work. A later version of the paper was written while
visiting the Indian Statistical Institute (Delhi), with support from the Subdireccidn General de
Cooperacidn Intemacional. I thank to all these persons and institutions for their help.
