摘要：The theory of equalising differences recognises that wage differentials may be required to equalise the attractiveness of alternative occupations. We examine this theory using the Conley/Wooders 'crowding types'' model. The crowding types model distinguishes between the tastes of a player and his crowding type, those attributes of the player that directly effect the well-being of other players in the same club - a player''s skill, productivity or personality are examples. A club can be interpreted as firm in which the job attributes are the club goods thus, the crowding types model, with its distinction between tastes and crowding types, provides a natural environment in which to study equalising differences. In contrast to results for earlier models, we demonstrate that even when small groups of players are strictly effective in a strong sense, an increase in the abundance of players of one crowding type can increase the core payoffs to players of that crowding type.
