 A note on the Drèze’s criterion for large capitalist firmsJean-Marc Bonnisseau and Oussama Lachiri () Cahiers de la Maison des Sciences Economiques from Université Panthéon-Sorbonne (Paris 1) Abstract: The paper extends the Drèze's Criterion [Investment under private ownership: optimality, equilibrium and stability, in «Allocation under Uncertainty; Equilibrium and Optimality», Wiley, New York, 1974, p.129] for firms to non-smooth and non-convex technologies and to non-ordered preferences for the consumers. Technically, the proofs follow the lines of Guesnerie [Pareto Optimality in Non-convex Economies, in Econometrica, 43, p.1-31, (1975)]. Using recent tools of non-smooth analysis, we exhibit the first-order-necessary conditions for constrained Pareto optimal allocations. The Drèze's criterion for firms is recovered, but the profit maximization is replaced by a first-order- necessary condition for optimality, together with other relations between state prices and consumptions. A new stock-market equilibrium is formalized. We show that stock holders buy nothing but stocks of a firm that maximize his expected profit with respect to his own shadow price Keywords: Stock market; non-smooth analysis; present value; market value (search for similar items in EconPapers) Downloads: (external link) Related works: Export reference: BibTeX RIS (EndNote, ProCite, RefMan) HTML/Text Persistent link: https://EconPapers.repec.org/RePEc:mse:wpsorb:b04120 Access Statistics for this paper More papers in Cahiers de la Maison des Sciences Economiques from Université Panthéon-Sorbonne (Paris 1) Contact information at EDIRC. |
