P. Zaleski et C. Zech, THE OPTIMAL SIZE OF A RELIGIOUS CONGREGATION - AN ECONOMIC-THEORY OF CLUBS ANALYSIS, The American journal of economics and sociology, 54(4), 1995, pp. 439-453
The economic theory of clubs model is applied to determine the optimal
size of a religious congregation. The optimal size is specified to be
where total contributions are maximized. This occurs where the margin
al benefits of adding a new member (in terms of contributions gained f
rom that new member) equal the marginal costs of that new member (in t
erms of contributions lost from existing members). Benefits from addin
g members include enhanced fellowship opportunities and the spreading
of fixed costs across a broader base. Costs include the congestion of
facilities and a greater tendency to free ride. The model is empirical
ly tested for four denominations. The average Catholic parish is found
to be much larger than its optimal size, while the average Episcopali
an, Lutheran, and Methodist congregations are all found to be smaller
than their optimal size.
