It is well known that the analysis of efficient specialization in Ricardian production with many countries and many commodities cannot be broken down to the simple case of two countries and two commodities. By drawing on some recent results of convex geometry and the theory of cephoids, this...

Assuming isoelastic returns to education and an endogenous supply of qualified and nonqualified labour, it is shown to be second-best efficient not to distort the choice of education. Furthermore, taxation should set incentives so that qualified labour is substituted for nonqualified labour. As...

Assuming a two-period model with endogenous choices of labour, education, and saving, it is shown to be second-best efficient to deviate from Ramsey's Rule and to distort qualified labour less than nonqualified labour. Furthermore, if the earnings function displays constant elasticity, the...

The planning of health care capacities is in practice constrained by sectoral and regional boundaries and it remains difficult to ensure an adequate and even access to health care. Moreover, standard planning approaches lack the choice-theoretic grounding necessary for making reliable statements...
