题目：Information Asymmetry, Ability, and Age at First Marriage
论文摘要： We build a simple model that integrates two types of contrary hypotheses on the relationship between wage and age at first marriage to explore how individuals make marriage decisions under information asymmetry. Using a Chinese adult twins data set, we employ the difference between identical and non-identical twins to identify the entire ability effect, and then utilize the different compositions of ability effects between wedding-time wages and current wages to distinguish ability income effect from ability revelation effect. Our empirical results provide several insights into the secret of age at first marriage. First, with information asymmetry, an individual with high realized wages marry early, whereas an advantageous-prospect individual will marry late; consistently, individuals obtaining a high wage growth rate at their young ages marry early, while individuals expecting a rapid wage growth in the future will marry late. Second, ability positively and negatively influences age at first marriage by wages and by channels other than wages, respectively; this suggests that information asymmetry exists in the labor market and people can accurately differentiate the marriage quality of an individual by observing his/her performances in addition to wages. Finally, a strong relationship exists between wages and men's age at first marriage; however, such a relationship is weak for females.
