Some countries economy are constant and some economy rise and fall, from my understanding I suggest that is because of the government, and population of the country. What is your suggestion
Both population and government make the economy rise and fall, the leadership of the government will decide their economic status and if their population is following all of the rules of the country. The relationship of the country to other country is also good for having a good economy, if your country is globalized then for sure your economy is high as well because of so many good transactions to other countries, good export and import are needed to gain strong globalization which result of a good economy.
