The wage curve [1] is the negative relationship between the levels of unemployment and wages that arises when these variables are expressed in local terms. According to David Blanchflower and Andrew Oswald (1994, p. 5), the wage curve summarizes the fact that "A worker who is employed in an area of high unemployment earns less than an identical individual who works in a region with low ...
The labour supply curve shows how changes in real wage rates might affect the number of hours worked by employees.. In economics, a backward-bending supply curve of labour, or backward-bending labour supply curve, is a graphical device showing a situation in which as real (inflation-corrected) wages increase beyond a certain level, people will substitute time previously devoted for paid work ...
w is the wage rate a is labour productivity n is the labour force. which are all functions of time (although the time subscripts have been suppressed for convenience) and the constants α is the rate of growth of labour productivity β is the rate of growth of the labour force γ is used to define the real wage change curve
From a Marxist perspective, a labour supply is a core requirement in a capitalist society.To avoid labour shortage and ensure a labour supply, a large portion of the population must not possess sources of self-provisioning, which would let them be independent—and they must instead, to survive, be compelled to sell their labour for a subsistence wage.
The term "wage-price spiral" appeared in a 1937 New York Times article about the Little Steel strike. In the 1970s, US President Richard Nixon attempted to break what he saw as a "spiral" of prices and costs, by imposing a price freeze, with little effect. [2] Some sources distinguish between wage-price spirals and price-wage spirals. [3]
The graph depicts an increase (that is, right-shift) in demand from D 1 to D 2 along with the consequent increase in price and quantity required to reach a new equilibrium point on the supply curve (S). A common and specific example is the supply-and-demand graph shown at right.

In the diagram, the long-run Phillips curve is the vertical red line. The NAIRU theory says that when unemployment is at the rate defined by this line, inflation will be stable. However, in the short-run policymakers will face an inflation-unemployment rate trade-off marked by the "Initial Short-Run Phillips Curve" in the graph.
