What can cause an economy to rise and fall is loss of confidence by consumers; when consumers lose confidence they will stop demanding , and a decrease in demand means that there will be a fall. When Consumers stop investing in businesses in a particular country and when those businesses start to fall, the economy of the country starts to fall because consumers (or should I say investors?) are moving their demands elsewhere.

There are so many things that can lead to these loss of interest and confidence to happen and it can be things like deregulation, poor management, deflation, and the rest of them.
