The traditional Phillips curve story starts with a wage Phillips Curve, of the sort described by Phillips himself. This describes the rate of growth of money wages ( gW ). Here and below, the operator g is the equivalent of "the percentage rate of growth of" the variable that follows.
The dynamic AS curve slopes upward, reflecting the mechanisms of the Phillips curve: Other things equal, higher levels of activity reflect higher increases in wages and other marginal costs of production, causing higher inflation through the firms' price-setting mechanisms [3]: 263 [5]: 409 as they induce firms to raise their prices at a higher ...
Aggregate supply curve showing the three ranges: Keynesian, Intermediate, and Classical. In the Classical range, the economy is producing at full employment. In economics , aggregate supply ( AS ) or domestic final supply ( DFS ) is the total supply of goods and services that firms in a national economy plan on selling during a specific time ...
Phillips Machine in the Science Museum, London. The Phillips Machine, also known as the MONIAC (Monetary National Income Analogue Computer), Phillips Hydraulic Computer and the Financephalograph, is an analogue computer which uses fluidic logic to model the workings of an economy.
William Phillips, an economist and creator of the Phillips curve, invented the MONIAC, a hydraulic computer which simulated the British economy. [3] [4] [5] This is the inspiration for the term. Even earlier, in 1891, Irving Fisher built a hydraulic machine for calculating equilibrium prices. [6]
The rationale behind Lucas's supply theory centers on how suppliers get information. Lucas claimed that suppliers had to respond to a "signal extraction" problem when making decisions based on prices; the firms had to determine what portion of price changes in their respective industries reflected a general change in nominal prices (inflation) and what portion reflected a change in real prices ...
The MP curve displays a positive relationship, upward-sloping curve, where the real interest rate is located on the vertical axis and inflation rate on the horizontal axis. Shifts on the MP curve are produced by actions of the Federal Reserve .
The aggregate demand curve is plotted with real output on the horizontal axis and the price level on the vertical axis. While it is theorized to be downward sloping, the Sonnenschein–Mantel–Debreu results show that the slope of the curve cannot be mathematically derived from assumptions about individual rational behavior.
