In this regard, we assess the effects of covid-19 on Investments, remittances, Trade, Tourism, Oil Prices, Production, Health, Education, Unemployment, and Air Line industry. Applying Exploratory Data Analysis (EDA) before (Jan 2019-Nov 2019) and after COVID-19 (Dec 2019- October 2020), we demonstrate that developed and transition economies witnessed remarkably low economic activities and shows a sudden and big investment outflows from transition economies, in addition to a huge cut in exports, Air Line Revenues, oil prices, over all production and employment after the pandemic. We also show increased political mistrust among world’s major economic players. Through a Panel data estimation on 160 countries weekly statistics, by applying simultaneous equation model we empirically capture the negative impact of COVID-19 on social and economic factors. We measure COVID-19 factor through a proxy index no. of affected persons in respective countries. In the end we come up with some policy recommendations for developed and transition economies.
