Acknowledgements This study was prepared for the “Final Meeting for ESRI International Collaboration Projects 2004” (February 15 and 16th, 2005 in Tokyo) sponsored by the Economic and Social Research Institute, Cabinet Office, Government of Japan. We would like to express our deep-felt thanks for the generous financial support provided by the Pfizer Health Research Foundation, the Japan Foundation Center for Global Partnership (through the Japan Center for Economic Research), the Economic and Social Research Institute of the Cabinet Office of Japan, the Health Care Financing Administration (through the California Medical Review, Inc.), and the National Institute on Aging. In addition, we are especially grateful to all the medical facilities that collaborated with us on this project. Moreover, we would also like to thank Professors Tadashi Yamada and Yasushi Iwamoto for their useful comments at the ESRI Projects. Our research project was approved by the Ethics Committee of the Department of Geriatrics, Nagoya University, and the medical facilities involved. All errors are our own.

N2 - In Japan, the use of percutaneous transluminal coronary angioplasty (PTCA) for the treatment of acute myocardial infarction (AMI) is extraordinarily frequent, resulting in large medical expenditure. Using chart-based data and exploiting regional variations, we explore what factors explain the frequent use of PTCA, employing propensity score matching to estimate the average treatment effects on hospital expenditure and hospital days. We find that the probability of receiving PTCA is affected by the density of medical resources in a region. Moreover, expenditure is higher for treated patients while there are no significant differences in hospitalization days, implying that the frequent use of PTCA is economically motivated.
