  abstract =	 {An economic model of trading in commodities that are
                  inherently indivisible, like houses, is investigated
                  from a game-theoretic point of view. The concepts of
                  balanced game and core are developed, and a general
                  theorem of Scarf's is applied to prove that the
                  market in question has a nonempty core, that is, at
                  least one outcome that no subset of traders can
                  improve upon. A number of examples are discussed,
                  and the final section reviews a series of other
                  models involving indivisible commodities, with
                  references to the literature.},
