How Long is Going to Take a Full Economic Recovery of the World Economy from COVID-19?

Abstract

This research attempts to evaluate how long the world economy takes for its economic recovery from the Post-COVID-19 period under the application of two new indicators called "COVID-19 Waves Oscillations (µ) and COVID-19 Openness Behaviour (ϔ)." The main objective is to evaluate the world economy recovery time framework from COVID-19, respectively. Firstly, the calculation of COVID-19 waves oscillation requests a holistic mathematical approach under the creation of a simple formula. This formula uses the interval of COVID-19 cases daily to elaborate a series of waves from Nano-Waves until Mega-Waves. At the same time, we will demonstrate how the COVID-19 waves oscillation can significantly impact COVID-19 openness behaviour (full business and financial activities reactivation in a month). Finally, we can elaborate on many simulations to evaluate how long it can take the world economy to full economic recovery from COVID-19.
