Public Policy Modeling and Applications 2021

As editors, we are glad to publish “Public Policy Modeling and Applications 2021” as an extended effort that builds upon the original Special Issue [1]. Indeed, policymakers continue to face the difficulties and intricacies of tackling complex societal issues [2]. The magnitude, heterogeneity, and idiosyncrasies of societal problems make modelling purposeful questions a hard, wicked task [3,4]. Moreover, translating quantitative and computational methodologies, along with their uncertainties and embedded assumptions, into simple—at times one-page—narratives for policymakers’ consumption may prove to be challenging [5]. Besides, only trying might already be informative [6].
