| Outline of Research at the Start |
We aim to study: (1) How much the end-of-life medical cost can account for the total medical spending for elderlies? Who are the high-medical-cost population, and how many are at the end-of-life? Any health insurance reform can slowdown the rising cost? (2) How much is by institutional factors, e.g., information and communication issues? (3) Comparing Japan with the US and Taiwan, what are the policy implications for aging population?

| Outline of Final Research Achievements |
We published one peer-reviewed paper in the top field journal (Journal of Labor Economics) using this research grant. Furthermore, we attended several international conferences and got invited by prestigious institutes for presentations. We found that over-use and under-use coexist in end-stage cancer treatments, with no survival benefits. Physician-patients use less surgery, radiation, or checkups but more targeted therapy and drugs; they enjoy higher survival and spend less on coinsurance. Knowledge mechanisms play a role because the network effect explains some, but not all, patterns. For less informed physician-patients, possessing a network is equivalent to reducing knowledge. The IZA (the Institute of Labor Economics) working paper series, a high-quality research network, has recognized our paper. This study uses unique administrative data from Taiwan's National Health Insurance database. This research grant has made these research achievements possible.
