Multivariate mixed proportional hazard modelling of the joint retirement of married couples
使用丹麦数据，通过多元混合比例风险模型分析夫妻退休时间的相互影响，发现夫妻休闲时间互补性强，个人低收入和健康不佳会促使个人提前退休，而高财富和低收入则推动夫妻同时退休。
Abstract We analyse the joint distribution of the durations until retirement of Danish husbands and wives. We estimate a multivariate mixed proportional hazards model that allows for interdependence in the times to retirement of spouses. We find evidence of strong complementarities in leisure times. Symmetrically for husband and wife, low own income and poor health are found to induce individual retirement (prior to spouse's retirement), whereas low spousal income is not, and neither party is found likely to substitute own for purchased care when the spouse is in poor health. Furthermore, high wealth and low income are found to spur joint (simultaneous) retirement. Copyright © 2004 John Wiley & Sons, Ltd.
