Competitive equilibrium with equal income (CEEI) is considered one of the best mechanisms to allocate a set of items among agents fairly and efficiently. In this paper, we study the computation of CEEI when items are chores that are disliked (negatively valued) by agents, under 1-homogeneous and concave utility functions which includes linear functions as a subcase. It is well-known that, even with linear utilities, the set of CEEI may be non-convex and disconnected, and the problem is PPAD… Expand

This paper considers the case of mixed manna under linear utilities where some items are positive goods liked by all agents, some are bads that no one likes, and remaining some agents like and others dislike, and proposes a polynomial-time algorithm for computing a CE of mixedManna when the number of agents or items is constant.

It is shown that for general (non-separable) PLC utilities, an exact equilibrium can be found in polynomial time provided the number of goods is constant, and if the utilities are separable piece-wise linear concave (PLC) functions, then it is shown they can be computed in poynomial time. Expand
