    　View Summary

    2021年度は、まず2020年度に行った調査の結果をとりまとめ、政策立案者や関心の近い研究者が集まる研究会において2回報告する機会を得た。（2021年10月経済産業省プラットフォームエコノミクス研究会、小樽商科大学土曜研究会・SWEO）いずれの報告の場においても、デジタルプラットフォームのマルチホーミングの実態を計測したデータとその分析の新奇性に対して、研究者、政策立案者双方からの強い関心を得た。また、本研究が行っている消費者に対する調査の継続の必要性も強く指摘された。
    また2021年度は、前年度に実施した調査から得られた仮説をもとに、新たに分野横断的に事業展開をしているプラットフォーム企業に焦点を当てた調査を実施した。1つの企業グループが、旅行予約、フリーマーケット、決済等、全20前後の複数分野のプラットフォーム市場で事業展開を行っており、それらが共通ポイント付与（数量割引の一種）や、アカウントの共通化などの連携を広く展開している。調査では、当該グループのサービスの利用割合が他サービスの利用状況によってどのような影響を受けるのか、また、当該市場におけるシングルホーミング・マルチホーミングどちらの割合が高まるのかに着目して分析を行った。このような分野横断的な調査はこれまで大規模に調査されておらず、プラットフォーム市場のより一層の理解に大きな貢献ができると考えている。例えばグループ内事業複数利用のドライバーとなるような事業を見極めるための分析を行うなど、様々な視点から分析を行っている。
    理論研究では、1本の論文の公刊と2回の学会報告を行うことができた。これらの理論モデルをデータから得られた示唆を盛り込む形で拡張する作業に取り組んでいる。

  • Research on Establishment of Statistics of Cashless Payment and its Impact on Economy

    Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), FUJIWARA KENYA, Grant-in-Aid for Scientific Research (B), No Setting

    　View Summary

    In this project, regarding cashless payment, one of the government's KPIs (Key Performance Indicators), we ① developed various statistics and databases, and ② conducted theoretical and empirical research on the impact of cashless payment on the financial and economic system in terms of consumer behavior, impact on the store, impact on the payment platform, and impact on macroeconomic policy management. In order to evaluate the benefits and challenges of cashless society, it is important to accumulate basic statistics and data-based research.

  • Sources of complementarities among firms and policy design

    2022.03

    Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Early-Career Scientists, Wakamori Naoki, Grant-in-Aid for Early-Career Scientists, Principal investigator

    　View Summary

    This project aims to seek sources of synergies when firms merge or forming coalition to work on the same project and examine the impacts of such synergies on firms' behaviors. Understanding sources of synergies is important for better designing policies. To this end, using unique data from the Pre-WWII Japanese electricity industry, I found that firms could enjoy cost synergies when merging with firms with greater differences in production asset composition and reachable customers. However, these synergies did not affect the merger decisions; instead of cost synergies, geographical proximity increased the likelihood of mergers, which might result in higher market power for the merged firms. These results illuminate the importance of competition policy.
