We extend our validated system dynamics models that we deployed 11 years ago during the credit crisis to model the production lockdown caused by the Covid-19 crisis. We estimate the supply chain dynamics that we may see unfold over the next few months. Our results suggest that inventory dynamics...

When the COVID-19 pandemic began in 2020, the medical product industry faced an unprecedented demand shock for personal protective equipment (PPE), including face masks, face shields, disinfectants, and gowns. Companies from various industries responded to the urgent need for these potentially...
