We provide three alternative characterizations of the proportional solution defined on <i>compact</i> and <i>comprehensive</i> bargaining problems with claims that are not necessarily convex. One characterization result is obtained by using, together with other standard axioms, two solidarity axioms. Another...

This paper investigates the existence of pure strategy, dominant-strategy, and mixed strategy Nash equilibria in discontinuous and nonconvex games. We introduce a new notion of very weak continuity, called weak transfer continuity, which holds in a large class of discontinuous economic games and...

This paper characterizes the existence of equilibria in minimax inequalities without assuming any form of quasi-concavity of functions and convexity or compactness of choice sets. A new condition, called “local dominatedness property”, is shown to be necessary and further, under some mild...

In production economies, the extent to which non-equilibria are blocked depends on specific rules that allocate authority among shareholders, because a blocking coalition's resources are affected by the firms it jointly owns with outsiders. Based on a notion of stochastic blocking, we extend...

The objective of this paper is to investigate if and how capital adjustment departs from the smooth pattern implied by standard model based on convex adjustment costs. Using Norwegian micro data, we start by documenting various aspects of the distribution of investment rates. We then present two...

In this paper we relax the convexity condition in some classical results on the existence of maximal elements in binary relations in order to generalize them. To do this, we replace the linear segments in the usual convexity with a family of previously fixed paths joining up each two points....
