Abstract
We consider marriage markets with externalities. We focus on weak externalities, that is, markets in which each agent is primarily concerned about her partner. We formalize and prove the claim that weak externalities are not so significant in the marriage market: in this case, the ω-core and the α-core coincide and are both nonempty. In addition, we show that, if we allow agents to block matchings without changing their mate, the results do not longer hold.
期刊介绍：
The Bulletin of Economic Research is an international journal publishing articles across the entire field of economics, econometrics and economic history. The Bulletin contains original theoretical, applied and empirical work which makes a substantial contribution to the subject and is of broad interest to economists. We welcome submissions in all fields and, with the Bulletin expanding in new areas, we particularly encourage submissions in the fields of experimental economics, financial econometrics and health economics. In addition to full-length articles the Bulletin publishes refereed shorter articles, notes and comments; authoritative survey articles in all areas of economics and special themed issues.
