We show that the empirical process of the squared residuals of an ARCH(p) sequence converges in distribution to a Gaussian process B (F(t)) + tf(t)E , where F is the distribution function of the squared innovations, f its derivative, {B(t), 0= t = 1} a Brownian bridge and E a normal random...

This paper provides necessary and sufficient conditions for input (or output) aggregation of efficiency indices. As such it parallels earlier arguments in the capital aggregation literature. The resulting quantity-dependent indices provide a rationalisation of the Debreu/Farrell efficiency...

We consider a two-period overlapping generations economy in which individuals work in both periods and acquire skills when young through both learning-by-doing and formal education. We characterise the unique saddle-path stable steady state of this economy and show that individuals spend too...

The paper proposes a simple mechanism, also applicable to certain models of internal bargaining, that induces firms to eliminate practically all efficiency losses and to react normally to changes in exogeneous variables.

This paper studies the theoretical effects of public policies on growth by stressing the major incidence of both the tax structure and the public education supply. Given an education supply, an increase in the progressivity of income taxation shortens the educational effort since the benefits to...

We present a new extension of the Shapley value for games with communication structure,only pairwise meetings can occur when some of them are not permitted.The present extension is a new one and in particular it is di .erent from the Myerson value,from the position value,and from a previous...

L'objet de ce travail est de s'interroger sur l'aptitude de la fonction de gains de Mincer a saisir efficacement la relation Education-Salaire. Cette fonction a tres largement ete utilisee comme outil de mesure des rendements des investissements educatifs. Pourtant, elle repose sur des...
