ON THE LIVING ARRANGEMENTS OF ELDERLY WIDOWS*
利用1970年美国数据，估计了老年寡妇与子女同住或独居的经济模型，发现收入变化解释了1970-1990年间独居寡妇数量增长的约四分之三。
Between 1970 and 1990, the share of elderly widows living alone grew by 23.2% in the United States, whereas those living with their children decreased by a similar amount. We pose a variety of models for determining the living arrangements in which living together increases consumption because of economies of scale and may also provide utility directly. We estimate these models using the 1970 data and obtain an excellent fit. The estimated models predict that changes in the incomes of both the widow and her offspring generate three‐quarters of the increase in the number of widows living alone.
