Abstract
Diversified sourcing has traditionally been a popular approach for managing supply risk compared to disruption prevention. However, COVID-19 crisis has emphasized the critical importanceof disruption prevention. Additionally, the economic fears arising from the crisis have led managers to adopt a more risk-averse stance. Despite the growing importance of risk aversion, existing studies have primarily focused on examining the impact of risk aversion on a specific approach, disregarding its influence on the selection of different approaches. As companies recognized the importance of investing in reliability to prevent disruptions, this research aims to investigate how risk aversion affects the selection of approaches to mitigate supply disruptions. Within a framework where both diversified sourcing and disruption prevention offer equivalent payoffs for risk-neutral buyers, our study unveils that risk-averse buyers, particularly when the level of disruption risk is relatively low and their risk aversion is relatively high, prefer to ‘‘mitigate but retain the risk of disruption" through diversified sourcing or partial prevention. This stands in contrast to risk-neutral buyers who consistently make choices between completely avoiding risk or accepting all risk through sole sourcing or no/complete prevention. More interestingly, the adoption of diversified sourcing and partial prevention yields distinct payoffs for risk-averse buyers.
