Comment on “Geographic Diversification of the Supply Chains of Japanese Firms”

Problem definition: This paper provides empirical evidence on the effect of the 2011 Great East Japan Earthquake (GEJE) on the financial performance of firms. Academic/practical relevance: The GEJE was characterized as the most significant disruption ever for global supply chains. In its aftermath, there was a great deal of debate about the risks and vulnerabilities of global supply chains, and there were calls to redesign and restructure supply chains. Methodology: We empirically estimate the effect of the GEJE on the stock prices of firms. Our analyses are based on a global sample of 470 firms collected from articles and announcements in the business press that identify affected firms, as well as 382 firms that are not mentioned in the business press but are in industries potentially subject to contagion or competitive effects. Results: We estimate that firms experiencing supply chain disruptions as a result of the GEJE lost on average 5.21% of their shareholder value during the one-month period after the GEJE. For Japanese firms, the effect was much more severe with an average 9.32% loss in shareholder value. Non-Japanese firms averaged a 3.73% loss in shareholder value. We also find that upstream and downstream supply chain propagation effects from the GEJE are negative, and the contagion effect on firms related to the nuclear industry is very negative. For firms in the rebuilding industries or competitors to firms affected by the GEJE, the competitive effect from the GEJE is positive. Managerial implications: The loss suffered by both Japanese firms and non-Japanese firms experiencing supply chain disruptions as a result of the GEJE is economically significant. Although the loss is more severe for firms whose operations were directly affected by the GEJE, it is also significant for firms who experienced indirect effects from their upstream and downstream supply chain partners, further confirming the importance of supply chain risk mitigation strategies.

Codes Of Conduct

Insbesondere in komplexen Supply Chains ist es heute üblich, dass Kunden ihre Lieferanten über Selbstverpflichtungserklärungen (Codes of Conduct) steuern. Forschungen aus anderen Industrien zeigen die Möglichkeiten, aber auch Grenzen der Arbeit mit diesem Instrument des Lieferantenmanagements. Davon können auch Krankenhauseinkäufer profitieren.
