ABSTRACT In the past three years, companies across the globe have witnessed significant supply chain disruptions due to the COVID-19 pandemic, which highlights the importance of managing supply risk. Supply risk has increased in the last three decades due to an increasing prevalence of concentrated supplier bases. We predict that firms with high supplier-base concentration will choose a more elastic cost structure in response to the increased supply risk. Using a unique dataset of 4,530 firm-year observations hand-collected from supplier information disclosed by Chinese-listed firms, we document a positive association between supplier-base concentration and cost elasticity. Furthermore, results from five cross-sectional tests are consistent with supply risk driving the association between supplier-base concentration and cost elasticity. Our study provides important practical implications to managers. To the extent that supplier-base concentration poses a supply risk, our study suggests that managers can respond by making the cost structure more flexible. Data Availability: Data are available from the public sources cited in the text. JEL Classifications: L23; M41.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
