Assortative Mating and Divorce: Evidence from Austrian Register Data
利用奥地利登记数据，研究发现过去四十年间年龄、民族、宗教和教育方面的同型婚配模式变化并非离婚率上升的原因，而结婚年龄推迟反而抑制了离婚率上升，移民和世俗化对离婚率无整体影响。
Summary We show that changes in assortative mating patterns along the dimensions of age, ethnicity, religion and education are not responsible for the increasing marital instability over the last four decades in Austria. Without the rise in the age at marriage, divorce rates would be considerably higher. Immigration and secularization, and the resulting supply of spouses with diverse ethnicity and religious denominations had no overall effect on divorce rates. Countervailing effects—in line with theoretical predictions–offset each other. The rise in the incidence of divorce is most probably caused by increased social acceptance of divorce.
