The walras algorithm calculates competitive equilibria via a distributed tatonnement-like process, in which agents submit single-good demand functions to market-clearing auctions. The algorithm is asynchronous and decentralized with respect to both agents and markets, making it suitable for distributed implementation. We present a formal description of this algorithm, and prove that it converge...
Recent literature shows that learning in oligopoly games might in the long run result in the Cournot or in the Walras equilibrium. Which outcome is achieved seems to depend on the underlying learning dynamics. This paper analyzes the forces behind the learning mechanisms determining the long run outcome. Apart from the fact that there is a difference between social and individual learning, the ...
In 1973 Economica devoted its February issue to celebrating Sir John Hicks. On that occasion, Hicks’s famous monograph Value and Capital (1939) was hailed as “the book that transformed economic theory” (p. 1). Nowadays Value and Capital (henceforth VC) is viewed as the starting point of the so-called neo-Walrasian research programme. From at least the 1970s Hicks himself endorsed that qualifica...
We consider a pure exchange economy with finitely many indivisible commodities that are available only in integer quantities. We prove that in such an economy with a sufficiently large number of agents, but finitely many agents, the strong core coincides with the set of cost-minimized Walras allocations. Because of the indivisibility, the preference maximization does not imply the cost minimiza...

In this paper, we study three prototypical models of noncooperative oligopoly in markets with a continuum of traders: the model of Cournot-Walras equilibrium of Codognato and Gabszewicz (1991), the model of Cournot-Nash equilibrium of Lloyd S. Shapley, and the model of Cournot-Walras equilibrium of Busetto et al. (2008). We argue that these models are all distinct and only the Shapley’s model w...
