CPM, which stands for Cost-Per-Mille (Mille is Latin for âthousandâ), is when the price is based on 1,000 impressions.
What causes inflation is also a key argument in economic theory. Some economists believe that there are different types of inflation â cost-push and demand-pull inflation. Cost-push inflation is supposed to be a type of inflation caused by rising prices in goods or services with no suitable alternatives. An oft-cited example of this inflation is the oil crisis of the 1970s.
To combat the negative impact of inflation, returns on some types of fixed income securities are linked to changes in inflation: 1  Floating-rate notes offer coupons that rise and fall with key interest rates. 2  Inflation-linked bonds issued by many federal governments are explicitly tied to changes in inflation.
