Effective responses to the COVID-19 pandemic require integrating behavioral factors such as risk-driven contact reduction, improved treatment, and adherence fatigue with asymptomatic transmission, disease acuity, and hospital capacity. We build one such model and estimate it for all 92 nations...

Essay 1- Effects of Feedback Delay on Learning. Learning figures prominently in many theories of organizations. Understanding barriers to learning is therefore central to understanding firms' performance. This essay investigates the role of time delays between taking an action and observing the...

Purpose – The purpose of this paper is to introduce econo-political risks (EPRs) to supply chains (SCs). Based on case data from an automotive SC, this research identifies the mechanisms through which a subset of EPRs influences SC operations and outcomes. Design/methodology/approach – An...

With so many possible choices, why do managers adopt the strategies they do? We identify delays between adopting a strategy and observing the full implications of that choice as a critical factor influencing strategic choices. Using a realistic simulation of a service firm, we conduct a...

When is it better to use agent based (AB) models, and when should differential equation (DE) models be used? Where DE models assume homogeneity and perfect mixing within compartments, AB models can capture heterogeneity in agent attributes and in the network of interactions among them. Using...

Projecting the course of infectious diseases and assessing the likely impact of policies to contain them require reliable estimates of the parameters in dynamic models of disease transmission. However, such estimation is difficult, especially for emerging diseases such as COVID-19, due to...
