The paper generalizes the natural projection approach introduced by Balasko (1988) to production economies with uncertainty. It explores the equilibrium structure of the long run and short run private ownership production model. It is shown that qualitative equilibrium properties of the...

This paper shows that the inverse image of the natural projection defines a ramified covering with finite layers. Finiteness of equilibria for regular two period production economies with uncertainty follows from this property.

This paper considers the financing of production in a two period general equilibrium model with incomplete markets. This requires a model where the efficient boundary of the production set available to a producer in period two in every state of the world is not independent of the financial...

Short and long run production is introduced in a two period general equilibrium model with incomplete markets, where firms are profit maximizers. They maximize profits in the long run, which implies profit maximization over both periods. The sequential structure of the model is such that, firms...
