Analyzing Economic Downturn With The Global Pandemic Timeline In Order To Improve The Sustainability Of B40 And M40 Groups

Rational speculative bubbles are a factor that has often led to the collapse of the
economy. In this study, the size of rational speculative bubble from the first cycle to the fifth
cycle are identified by using a generalised Johansen-Ledoit-Sornette Model. This study
also discussed the effects of the burst of the rational speculative bubble also known as the
financial bubble. Then, the economic performance of the countries that pioneered the world
economy will be analysed along with the stock prices, the performance of Gross Domestic
Product (GDP) and the timeline of the global pandemic. Lastly, this paper discussed the
effects of the existence of financial bubble and the presence of pandemics towards the
sustainability of the living standards for the B40 and M40 household groups in Malaysia.
