Abstract: Economists have long conceptualized and modeled the inherent interdependent relationships among different sectors of the economy. This concept paved the way for input‐output modeling, a methodology that accounts for sector interdependencies governing the magnitude and extent of ripple effects due to changes in the economic structure of a region or nation. Recent extensions to input‐output modeling have enhanced the model's capabilities to account for the impact of an economic perturbation; two such examples are the inoperability input‐output model(1,2) and the dynamic inoperability input‐output model (DIIM).(3) These models introduced sector inoperability, or the inability to satisfy as‐planned production levels, into input‐output modeling. While these models provide insights for understanding the impacts of inoperability, there are several aspects of the current formulation that do not account for complexities associated with certain disasters, such as a pandemic. This article proposes further enhancements to the DIIM to account for economic productivity losses resulting primarily from workforce disruptions. A pandemic is a unique disaster because the majority of its direct impacts are workforce related. The article develops a modeling framework to account for workforce inoperability and recovery factors. The proposed workforce‐explicit enhancements to the DIIM are demonstrated in a case study to simulate a pandemic scenario in the Commonwealth of Virginia.
