Research Talk by Prof. Sunil Mithas Post


From a healthcare pandemic (e.g., Covid19) to a military conflict (e.g., Ukraine war), geopolitical and economic uncertainties are all too common in retailing. Although retailers are investing in digital technologies to secure their businesses, such investments are infrequent, heterogeneous, and difficult to track, complicating the assessment of retailers’ ability to build digital resilience. Information provided in financial reports such as 10-Ks may be effectively used to measure the level of digital resilience, i.e., the extent of preparedness through digital capabilities building over time to tackle uncertainties. In this study, we use textual information from 10-Ks to effectively assess digital resilience. Using a dataset of 10-Ks from 2005 to 2020, we use human coders and neural word embeddings to develop a digital resilience dictionary specifically crafted to identify features relevant to risks, assets, customer relationship management, and operations management. The use of the dictionary provides a novel way to explain retailers’ performance based on the extent of features that are relevant to risks-assets and customer relationship management-operations management. To the extent that 10-Ks offer some visibility into the digital resilience of retailers, we argue that features related to risks and operation management explain low retailer performance while features related to assets and operation management explain high retailer performance. Moreover, we posit that features related to risks and customer relationship management mitigate the effect of risks-operation management on retailer performance while features related to assets and customer relationship amplify the effect of assets- operation management on retailer performance. Our work provides a novel approach for investors and policymakers to assess the digital resilience of retailers through the appropriate use of financial reports.
