The Impact of Employment on Parental Coresidence
利用1998-2012年美国健康与退休研究数据，发现成年儿子从全职转为非就业会使与父母同住的概率提高1.5个百分点，转为兼职则提高2个百分点；收入弹性为-1.1（儿子）和-0.5（女儿）。
Abstract We examine the extent to which parents use housing and shared living arrangements as a form of risk‐sharing for their adult children, using detailed data on children and parents in the Health and Retirement Study for 1998–2012. On average, a young man moving from full‐time to nonemployment raises the likelihood of coresiding with a parent by 1.5 percentage points; moving from full‐time employment to being part‐time employed raises the likelihood of coresiding with a parent by 2 percentage points. The implied elasticity of parental coresidence with respect to the son's income is ‐1.1; for daughters, the elasticity is ‐0.5.
