Some countries economy are constant and some economy rise and fall, from my understanding I suggest that is because of government,and population of the country. What is your suggestion
Rise and fall is a common trend of every economy of the world. There is no economy in the world which goes only for rising or falling. There are different factors for this cause. The main factors are international business policy and relation, natural disaster, political situation, epidemic, govt. policy, export and import, economic and social condition, availability of factors of production etc. There are different stages of this business cycle of the economy like expansion, peak, recession, great depression etc. Economy is not stable, It always fluctuates within the cycle.
