Entry Models Applied to Churches: Could Protestants use a Catholic Bishop to Solve Excess Entry?
研究了天主教和新教教堂在不同城镇的进入数量差异，发现新教教堂的分散化进入导致数量过多，而天主教由主教集中控制进入则数量较少，模拟表明集中化可减少新教教堂的过度进入。
This paper studies the entry behavior of churches of different religious denominations. In a given town, there tend to be fewer Catholic churches (with more members) than there are Protestant churches. Entry of Catholic churches can be considered centralized, since entry is controlled by a bishop; whereas, the entry of Protestant churches is rather decentralized. I estimate an entry game for Protestants, then conduct counterfactuals looking at how entry would change if it were centralized. I find that a large portion of the differences in entry between Catholic and Protestant churches is explained by this difference in entry regulation.
