  • How do floods affect insurance demand? Evidence from flood insurance take-up in Japan

    Jie Shao, Akio Hoshino, Satoshi Nakaide

    International Journal of Disaster Risk Reduction   83  2022.12

     View Summary

    This study examines the hypothetical impact of floods on people's flood insurance purchase decisions, and how this impact may differ among people with different socioeconomic, geographic, and financial literacy characteristics. We find a significant yet short-lived (1-year) impact of floods on people's demand for flood insurance at an ecological level (prefectures). Different aspects of flood damage have different impacts on flood insurance take-up, with human casualties having the greatest impact on people's perception of flood risk. We also find that groups with different socioeconomic characteristics, such as age, education, and insurance agent density, react differently to floods concerning insurance purchases. We confirm a positive relationship between objective risk exposure and people's perception of the flood experience. Finally, an analysis of the Financial Literacy Survey demonstrates the impact of three cognitive biases (loss aversion, myopic, herding) on flood insurance take-up. These findings provide empirical evidence for various psychological and behavioral theories, and important policy references for countries aiming to develop flood insurance in the future.

     View Summary

    This study proposes a framework to explainpeople's risk preferences in a consistent manner and aims to quantitativelyevaluate risk preferences using this framework. The framework divides risk into threecategories: pure risk, speculative risk, and lottery risk. This explains theseemingly contradictory mix of risk-averse preferences for insurance andrisk-loving preferences for lotteries. The research plan is to conduct multiplesurveys over a two-year period and to measure the risk premium for each of thethree categories. This year's objectives were (1) to examinethe design of the survey, particularly the ease of understanding the survey questions by respondents,(2) to verify the validity of the method by conducting the first round of the survey,and (3) to obtain 1,000 valid responses.As of the end of March, (1) to (3) above progressedas expected. In FY2023, we plan to analyze the dataobtained from the first survey and measure the risk premium, design and conductthe second and subsequent surveys, analyze the data, and publish the results inforeign or domestic journals.
