We define two types of natural mechanisms, quantity and price-quantity types, in convex production economies, and characterize the class of Pareto subsolutions doubly implementable in Nash and strong Nash equilibria by these mechanisms respectively. First, we show that there is a class of Pareto...

This paper discusses issues of axiomatic bargaining problems over opportunity assignments. The fair arbitrator uses the principle of "equal opportunity" for all players to make the recommendation on resource allocations. A framework in such a context is developed and several classical solutions...

We study the general equilibrium effects of localised technical progress à la Atkinson-Stiglitz on income distribution in economies in which capital is a vector of reproducible and heterogeneous goods. We show that there is no obvious relation between ex-ante profitable innovations and the...

In the standard Okishio-Morishima approach, the existence of profits is proved to be equivalent to the exploitation of labour. Yet, it can also be proved that the existence of profits is equivalent to the ‘exploitation’ of any good. Labour and commodity exploitation are just different...

This paper provides a novel axiomatic analysis of exploitation as the unequal exchange of labour in economies with heterogeneous opti-mising agents endowed with unequal amounts of physical and human capital. A de.nition of exploitation is proposed, which emphasises the relational nature of...
