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.
Inflation Theory goes by several other names, including: 1  cosmological inflation. 2  cosmic inflation. 3  inflation. 4  old inflation (Guth's original, 1980 version of the theory) 5  new inflation theory (name for the version with the bubble problem fixed) 6  slow-roll inflation (name for the version with the bubble problem fixed)
