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.
A closely linked phenomenon to inflation is deflation, sometimes called negative inflation. Deflation occurs when there is a decreasing change in the price of goods and services. Inflation and deflation affect how a consumer can buy goods and the value of debt. Inflation can occur in wages or prices.
