  • Do regulatory loopholes distort technical change? Evidence from new vehicle launches under the Japanese fuel economy regulation

    Y Konishi, S Managi

    Journal of Environmental Economics and Management, 102377 (Elsevier)  104 2020.11

    Research paper (scientific journal), Accepted,  ISSN  00950696

    　View Summary

    © 2020 The Authors Environmental regulation often creates regulatory loopholes that are not ideal in first-best settings. Such loopholes affect the marginal costs of alternative compliance strategies, leading to distortion in firm's compliance choice. We quantify the unintended effect of such loopholes on technical change in the Japanese automobile industry, using variant-level data on new vehicle launches. We employ a triple difference strategy, exploiting the two-fold treatment-control structures within each product segment, due to regulation-induced variations in the Japanese fuel economy standards over time. Our results indicate that regulation-induced differences in technical trade-offs have induced a distortion not only in product attributes but also in technical progress in fuel economy technology.

  • Retiring for Better Health? Evidence from Health Investment Behaviors in Japan

    Konishi, Yoshifumi, Meng, Zhao

    Japan and the World Economy (Elsevier Science)  42   56 - 63 2017.06

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  09221425

    　View Summary

    © 2017 Elsevier B.V. This paper examines the causal effects of retirement on health investment behavior among Japanese permanent employees. We find that the Japanese employees participate less in unhealthy habits (smoking and drinking) after retiring from their permanent employment, and after completely ceasing to work, they further increase participation in healthy life habits (regular exercise). We also find gender differences in these responses.
