Social Science Research Network has a new paper from two economists on ring size and how long the wedding lasts:
In this paper, we evaluate the association between wedding spending and marriage duration using data from a survey of over 3,000 ever-married persons in the United States. Controlling for a number of demographic and relationship characteristics, we find evidence that marriage duration is inversely associated with spending on the engagement ring and wedding ceremony.Bigger ring and expensive wedding ceremony , the shorter marriage.
