The general price level is a hypothetical measure of overall prices for some set of goods and services (the consumer basket ), in an economy or monetary union during a given interval (generally one day), normalized relative to some base set. Typically, the general price level is approximated with a daily price index , normally the Daily CPI . The general price level can change more than once per day during hyperinflation .ContentsTheoretical foundation[ edit ]
The classical dichotomy is the assumption that there is a relatively clean distinction between overall increases or decreases in prices and underlying, “nominal” economic variables. Thus, if prices overall increase or decrease, it is assumed that this change can be decomposed as follows:
Given a set of goods and services, the total value of transactions in at time is∑∈⋅∑∈⋅⋅⋅∑∈⋅
whererepresents the quantity of at time represents the prevailing price of at time represents the “real” price of at time is the price level at time
The general price level is distinguished from a price index in that the existence of the former depends upon the classical dichotomy, while the latter is simply a computation, and many such will be possible regardless of whether they are meaningful.Significance[ edit ]
If, indeed, a general price level component could be distinguished, then it would be possible to measure the difference in overall prices between two regions or intervals. For example, the inflation rate could be measured as−− edit ]
Applicable indices are the consumer price index (CPI), Default Price Deflator, and the Producer Price Index.
