The Marshallian Macroeconomic Model in Zellner and Israilevich (2005) provides a novel way to examine sectoral dynamics through the introduction of a dynamic entry/exit equation in addition to the usual demand and supply functions found in models of this class. In this paper we examine the...

Investors in financial markets face several restrictions apart from wealth constraints. The first attempt to understand these restrictions in a general competitive equilibrium framework can be traced back to Radner (1972). Here these restrictions are assumed to be given exogenously, as first...

We consider a multiperiod financial exchange economy with nominal assets and restricted participation, where each agent's portfolio choice is restricted to a closed, convex set containing zero, as in Siconolfi (1989). Using an approach that dates back to Cass (1984, 2006) in the unconstrained...

This paper considers an exchange economy with a measure space of agents and consumption externalities, which take into account two possible external eects in consumers¡¯ preferences: the dependence upon prices and other agents¡¯ consumptions, respectively, as in Greenberg et al. [12] and...

We consider the model of a stochastic financial exchange economy where time and uncertainty are represented by a finite event-tree of length T. We provide a general existence result of financial equilibria, which allows to cover several important cases of financial structures considered in the...

It is shown that, in the framework of Gelfand integrable mappings, the Fatou-type lemma for integrably bounded mappings, due to Cornet?Medecin [14] and the Fatou-type lemma for uniformly integrable mappings due to Balder [9], can be generalized to mean norm bounded integrable mappings

In a financial economy with asymmetric information and incomplete markets, we study how agents, having no model of how equilibrium prices are determined, may still refine their information by eliminating sequentially ¡°arbitrage state(s)¡±, namely, the state(s) which would grant the agent an...

This paper deals with the existence of marginal pricing equilibria when it is defined by using a new and tighter normal cone introducedby B. Cornet and M.O. Czarnecki. The main interest of this new definition of the marginal pricing rule comes from the fact that it is more precise in the sense...
