Toward a Theory of Membership Association Finance
本文比较了收入组合理论与福利理论，利用新数据库发现协会收入受会员福利与社会福利平衡的约束，而非追求多样化。
This article explores patterns in membership associations’ portfolios. It compares and contrasts portfolio theory, which predicts variety in revenue portfolios, with a newer benefits theory, which postulates that revenue options are constrained by the balance between the member benefits and societal benefits they produce. The research makes use of a new database that more accurately measures dues and program service revenue of associations than other databases. The weight of the evidence supports benefits theory more strongly than revenue portfolio theory. This research incidentally finds that revenue concentration increases with size and decreases with real estate ownership. The article introduces the concepts of one-off entry and exit costs on members (tariffs), which tend to reduce members’ sensitivity to the level of dues. Indeed, dues are often dominant among the associations having presumptively high tariffs, such as trade unions and certain recreational clubs.
