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 classical general equilibrium model aims to describe the economy by aggregating the behavior of individuals and firms. [1] Note that the classical general equilibrium model is unrelated to classical economics , and was instead developed within neoclassical economics beginning in the late 19th century.
Classical economics, also known as the classical school of economics, [1] or classical political economy, is a school of thought in political economy that flourished, primarily in Britain, in the late 18th and early-to-mid 19th century.
In new classical models, the macroeconomy is assumed to be at its unique equilibrium, with full employment and potential output, and that this equilibrium is assumed to always have been achieved via price and wage adjustment (market clearing).
Keynes did not lay out an explicit theory of price level. [65] Early Keynesian models assumed wage and other price levels were fixed. [66] These assumptions caused little concern in the 1950s when inflation was stable, but by the mid-1960s inflation increased and became an issue for macroeconomic models. [67]
The quantity of aggregate output supplied is highly sensitive to the price level, as seen in the flat region of the curve in the above diagram. Long-run aggregate supply (LRAS) — Over the long run, only capital, labour, and technology affect the LRAS in the macroeconomic model because at this point everything in the economy is assumed to be ...

In particular, after inflation became important in the late 1960s and 1970s, there was a need to complement the IS–LM model, which had been a dominant model for teaching purposes until that time, but assumed a constant price level, with a model that incorporated aggregate supply and consequently could provide an explanation of changes in the ...
