The general price level is a hypothetical daily 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. == Theoretical foundation == 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 : where : represents 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Price level」の詳細全文を読む スポンサード リンク
