Document Summary

The overall increase in prices overtime o prices increase either slowly over time, or rapidly in a period of economic trouble: hyperinflation is when the price increases substantially ex: zimbabwe"s prices increase by 24,000% The level of prices and the value of money. Supply and demand for money determines its value o demand for money reflects how much wealth people want to hold in liquid form or. Canada which is high: price would have to go up in order to this issue and bring equilibrium. When the bank of canada injects more money into the economy by buying bonds, money supply increases, the price level also increases which makes each dollar less valuable lomoarcpsd| 2151316. The quantity theory of money states that the quantity of money available determines the price level, and growth in such quantity determines the inflation rate: thus when money supply grows, the value of money decreases.
