Till Death Do Us Part or I Get My Pension? Wives' Pension Holding and Marital Dissolution in the United States
研究美国妻子持有养老金对婚姻解体的影响，发现单方程模型支持老年妻子独立性假说，但联立方程模型表明该解释可能误导。
Wives' financial independence gained from their pension may increase the risk of marital dissolution, especially when wives are approaching retirement age (the older wives' independence hypothesis). Applying single and simultaneous equations probit models to data from the Panel Study of Income Dynamics, we investigate the effect of wives' pension holding in 1984 on the risk of subsequent marital dissolution. Results from the single equation model appear to support the older wives' independence hypothesis. However, results from the simultaneous equations model suggest that interpreting the single equation results as a sign of older wives' economic independence may be misleading.
