Resumen de Portfolio Allocation within Parties: The Role of Regional Party Branches

Laurenz P. Ennser-Jedenastik

• One of the most persistent findings in coalition research is the proportionality rule (‘Gamson's Law’) that guides the allocation of portfolios between parties. This article tests the assumption that a similar rule is at work within parties. More specifically, it examines the allocation of ministerial posts to regional party branches in 25 post-war cabinets in Austria between 1945 and 2008. Drawing on the literature on party organisations, three types of resources (membership, vote and population shares) are identified, all of which account for a substantial part of the variation in the shares of cabinet seats awarded to each party branch. The analysis thus bears out the proportionality proposition to a significant degree. Furthermore, it is shown that there is considerable cross-party variation in the allocation patterns, which reflects differences in the organisational structure of the parties.
