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
If we are talking about rise and fall of economy during this exact year - it depends heavily on two factors:
1. structure of economy (US economy is based on high liquidity thats why they can't afford being in quarantine anymore, Switzerland economy is way more passive so they didn't feel the same as US)
2. decisions of government (if one country doesn't want to start a lockdown because they don't feel it as necessity - they are going to lose a lot of people and wealth only because of their decision)
There are some governments who did right decisions, but people simply ignored them - thats whole another deal
