Understanding Coronanomics: The economic implications of the coronavirus (COVID-19) pandemic

The globalization of COVID-19 pandemic and its economic impacts is set to run havoc across all economies in the world, throwing many into recession and possibly economic depression. As the numbers of infected and death cases rise sharply and recovery from the pandemic remains uncertain even in developed countries, evidence of shocks across economies including China, the Europe, and the US are already emerging. The aim of this paper is to provide an overall understanding of the likely macroeconomic shocks of the pandemic, covering economic activities or areas including demand, supply, supply chain, trade, investment, price level, exchange rates, and financial stability and risk, economic growth, and international cooperation. The paper first presents a general and theoretical mapping of the likely macroeconomic impacts of the pandemic on an affected economy and then reviews the emerging evidence in relation to the impact mapping to understand the nature of the impacts. The paper then illustrates the likely impacts using a standard macroeconomic AD-AS model and outlines some necessary features that needs to be considered while designing policy responses by governments and international institutions in mitigating the economic shocks. Assessments of this paper are broadly in line with the limited studies available on the economics of COVID-19.
