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.
Price inflation occurs when average prices are rising above this low and predictable rate, and price deflation occurs when average prices are falling. In both cases, the effects are potentially extremely harmful to a countryâs economic performance and to the welfare of its citizens.
