This paper examines the effect of health on labour force participation using the Household, Income and Labour Dynamics in Australia (HILDA) Survey. The potential endogeneity of health, especially self-assessed health, in the labour force participation equation is addressed by estimating the health equation and the labour force participation equation simultaneously. Taking into account the correlation between the error terms in the two equations, the estimation is conducted separately for males aged 15-49, males aged 50-64, females aged 15-49 and females aged 50-60. The results indicate that better health increases the probability of labour force participation for all four groups. However, the effect is larger for the older groups and for women. As for the feedback effect, it is found that labour force participation has a significant positive impact on older females' health, and a significant negative effect on younger males' health. For younger females and older males, the impact of labour force participation on health is not significant. The null-hypothesis of exogeneity of health to labour force participation is rejected for all groups.
本文利用澳大利亚家庭、收入与劳动力动态调查(HILDA)研究了健康状况对劳动力参与率的影响。通过同时估计健康方程和劳动力参与方程,解决了劳动力参与方程中健康状况(尤其是自我评估健康状况)可能存在的内生性问题。考虑到两个方程误差项之间的相关性,分别对15 - 49岁男性、50 - 64岁男性、15 - 49岁女性以及50 - 60岁女性进行了估计。结果表明,健康状况改善会增加所有这四组人群劳动力参与的概率。然而,对年龄较大的群体和女性来说,这种影响更大。至于反馈效应,研究发现劳动力参与对老年女性的健康有显著的积极影响,而对年轻男性的健康有显著的负面影响。对于年轻女性和老年男性,劳动力参与对健康的影响并不显著。所有群体的健康状况对劳动力参与的外生性原假设均被拒绝。
