  • 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.

  • Can Green Car Taxes Restore Efficiency? Evidence from the Japanese New Car Market

    Konishi, Yoshifumi, Zhao, Meng

    Journal of the Association of Environmental and Resource Economists （Journal of the Association of Environmental and Resource Economists)  4 （ 1 ） 51 - 87 2017.03

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  23335955

    　View Summary

    © 2017 by The Association of Environmental and Resource Economists. All rights reserved. To quantify the economic impacts of Japan’s feebate policy, a random-coefficients logit model is estimated for quarterly automobile sales between 2007 and 2012 from the Japanese new car market. For identification of the structural parameters, we exploit the policy-induced variation in effective car prices and the location of product-specific vehicle taxes as instruments. The estimated demand system allows us to simulate counterfactual Bertrand-Nash equilibria in response to alternative policy scenarios. Our results indicate that Japan’s feebate policy induced a sizable increase in economic surplus, yet only a small improvement in sales-weighted average fuel efficiency, relative to the no-policy counterfactual. We also design an optimal feebate policy, which maximizes total economic surplus subject to a tax revenue constraint, by explicitly accounting for market power, product attributes, and carbon dioxide emissions rates. The policy is predicted to induce sizable improvements in both economic surplus and average fuel efficiency over Japan’s feebate policy without requiring any decrease in tax revenues.
