In the last decade, with the publication of his Complete Works, there has been renewed interest in Walras’s methodology, mostly in the French economic literature. In particular, some scholars have argued that Walras characteristically confused positive and normative statements, a mistake all the more surprising given his impressive knowledge of philosophy (the so-called ‘Walras paradox’). This ...

The paper studies the core-Walras equivalence problem in the commodity space framework of Banach spaces, allocations being defined as Pettis integrable functions. In particular, a core-Walras equivalence result for a certain class of commodity spaces is established, without requiring that the commodity space be separable. The class covered by this result includes the Lp(μ) spaces, 1 ≤ p < ∞, μ ...

Aiyagari (1992) shows that equilibria are nonoptimal for an overlapping generations economy if and only if Walras’ Law fails. We demonstrate that this failure represents an earnings opportunity exploitable by unsecured debt issue. When unsecured debt is issued, Walras’ Law holds. JEL Classification: D5, D6, D9

In this paper, we respecify à la Cournot-Walras the mixed version of a model of noncooperative exchange, originally proposed by Lloyd S. Shapley. We first show that this respecification has a Cournot-Walras equilibrium allocation, which does not correspond to any CournotNash equilibrium of the mixed version of the original Shapley’s model. As this is due to the intrinsic two-stage nature of the...

This text is to appear in a volume produced at the occasion of the 100th anniversary of Léon Walras death. The first part (introduction) answers one initial demand (to the solicited authors), i.e the evaluation of Walras influence on their own research and more generally on contemporary research. The second part “Between the Capitol Hill and the Tarpeian Rock ? ” goes further into the discussio...

In this paper, in an exchange economy with atoms and an atomless part, we analyze the relationship between the set of the Cournot-Nash equilibrium allocations of a strategic market game and the set of the Walras equilibrium allocations of the exchange economy with which it is associated. In an example, we show that, even when atoms are countably infinite, Cournot-Nash equilibria yield different...

The author of this article draws special attention to two particular claims the free bankers concerning supposed working characteristics a fractional-reserve banking system which may strike reader as questionable. first these relates alleged absence real-balance effect under banking. second bankers’ reference Walras’ Law providing rationale for system’s «offsetting» actions when confronted with...
