The impact of post-COVID-19 on economic growth is obviously substantial, but measuring such impact to get a sense of the intensity of its effects on inflation and unemployment is subject to a great deal of uncertainty. As such, this paper primarily attempts to close this gap by introducing the COVIDECONOMICS-19-Simulator (COVIDECONOMICS-19-Simulator), a new economic instrument that could be used to evaluate the impact of post-COVID-19 on inflation and unemployment. Based on five key indicators, the COVIDECONOMICS-19-Simulator considers and draws its assessment from different focuses of analysis to evaluate the post-COVID-19 economic damage anywhere and anytime. Hence, in this article, the world economy was used to illuminate and illustrate the applicability of the COVIDECONOMICS-19-Simulator from where analyses provide a coherent evaluation of the degree to which post-COVID-19 negative economic effects on the world inflation and unemployment.
