What makes people anxious about life after the age of 65? Evidence from international survey research in Japan, the United States, China, and India
No full textJune 2012. Revised August 2013.Secondly Revised September 2015.This study investigated the causes of people’s anxieties about life after the age of 65 years, using household data from countries with different social contexts: Japan, the United States, China, and India. This research added contextual aspects to the literature on social security and precautionary savings. An ordered probit model was used to establish the causes of anxiety and a generalized structural equation model was used to check the robustness of the results. This study uncovered three major findings. First, anxiety levels about life at an older age partly depend on people’s views of the future. Second, high financial status lessens people’s anxiety levels only if prices are stable. Third, living with a child, contrary to expectations, does not necessarily lessen people’s concerns about life after 65
Revealed Preference Test and Shortest Path Problem; Graph Theoretic Structure of the Rationalizability Test
Get PDF* Revised： [15-17, 2015]* Revised： [15-17-Rev, 2015]This paper presents some substantial relationships between the revealed preference test for a data set and the shortest path problem of a weighted graph. We give a unified perspective of several forms of rationalizability tests based on the shortest path problem and an additional graph theoretic structure, which we call the shortest path problem with weight adjustment. Furthermore, the proposed structure is used to extend the result of Quah (2014), which sharpened the classical Afriat’s Theorem-type result
