For an exchange economy, under assumptions which did not bring about the existence of equilibrium with dividends as yet, we prove the non-emptiness of the fuzzy rejective core. Then, via Konovalov (1998, 2005)'s equivalence result, we solve the equilibrium with dividends existence problem....

This paper develops a dynamic model of competitive equilibrium in electricity markets with thermal, hydro and intermittent power sources. Thermal generators have positive and increasing costs and use a marketable input. Hydro generators use a free and uncertain input, but one that is storable....

Despite a widespread interest in the warm glow model [Andreoni (1989,1990)], surprisingly most attention focused on the voluntary contribution equilibrium of the model, and only very little attention has been devoted to the competitive equilibrium. In this paper, we introduce the notion of...
