Abstract
|
Before
We conduct a survey-based experiment to examine health insurance demand and overconfidence in health among married individuals. The aim is to provide direct evidence that individuals are overconfident about their own and their spouse's health risks and that they believe they are healthier than their spouses. Additionally, we will investigate how individuals update health-related information about themselves compared to their spouses. The questionnaire comprises six parts. The first part is for collecting basic information about the subjects and their spouses, including age and gender. The second part focuses on the subjects' perceptions of their own and their spouses' health risk. The third part explores how they update health-related information about themselves and their spouses. The fourth part collects health information for both the subjects and their spouses. The fifth part collects information on the subjects' and their spouses' occupation, education level, lifestyle habits, risk preferences, and commercial insurance purchases. Finally, the sixth part focuses on the potential effect of the experimenter's demand. We expect that the results of the experiment will provide valuable insights into health insurance demand and overconfidence among married individuals, shedding light on how they update and perceive health-related information about themselves and their spouses.

We conduct a survey-based experiment to examine health insurance demand and overconfidence in health among married individuals. The aim is to provide direct evidence that individuals are overconfident about their own and their spouse's health risks and that they believe they are healthier than their spouses. Additionally, we will investigate how individuals update health-related information about themselves compared to their spouses. The questionnaire comprises six parts. The first module aims to collect basic demographic data from respondents, including their gender, number of children, and weekly exercise time, as well as the same information about their spouses. The second module aims to elicit respondents' perceptions of the health risks. We ask respondents to compare their own health risks with those of their spouses, their own health risks with those of average people in their age and gender group, and their spouses' health risks with those of average people in their spouses' age and gender group. The third module introduces a survey experiment on belief updating. The fourth module collects health information on both respondents and their spouses. The fifth module gathers data on respondents' education levels, lifestyle habits, risk preferences, and private insurance purchases. Finally, the sixth module addresses potential experimenter demand effects; and we inquire whether the respondents trust the cancer news presented in the survey experiment and the extent to which they find others' health information helpful in shaping their beliefs about their own and their spouses' health risks.
