老人是否持有不動產與獨居之聯合決策分析─ 並由居住滿意度分析老人獨居之性質The Joint Decision Making of Holding Real Assets and Living Alone among Elderly People in Taiwan – And Understanding the Nature of Living Alone through the Satisfaction Level of Elderly People
Elderly people account for more than 10% of the total population in Taiwan. Among the issues related to elderly people, the increasing probability of living alone is attracting more and more attention from the whole of society. In this paper, we first establish a conceptual model to explain the causal relationships among holding assets, living alone and the level of satisfaction with living arrangements of elderly people. The data used in the empirical study are obtained from “The Survey of Health and Living Status of the Near Elderly and Elderly in Taiwan” for 1996 and 2007, which is conducted by the Department of Health. In the empirical study, a bivariate probit model is used first to estimate the joint decision making of holding assets and living alone. Then an ordered logistic regression is used for the satisfaction with living model. By combining the different findings from the empirical results, we note that aged people who hold real assets have a higher probability of living alone relative to those not holding any real assets. This is probably owing to the fact that they are not able to adapt to a new environment and decide to stay in their original residence alone. In other words, they live alone involuntarily, and hence have a lower level of satisfaction than those who hold assets and do not live alone.
Key words: elderly, living alone, real assets, level of satisfaction with living arrangements, bivariate probit model
