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.
Reflation, which can be considered a form of inflation (increase in the price level), is contrasted with inflation (narrowly speaking) in that bad inflation is inflation above the long-term trend line, while reflation is a recovery of the price level when it has fallen below the trend line.
