Real Wage Index Assumption for Phillips Curve Derivation
As a simplifying step in the graphical derivation of the Phillips curve from the WS-PS model, the real wage at the initial supply-side equilibrium is set to an index value of 100. This provides a clear baseline from which to measure changes as the economy moves away from equilibrium.

Consider a graphical model of the labor market where an upward-sloping 'wage-setting' relationship determines the real wage required to motivate workers at different levels of employment, and a horizontal 'price-setting' relationship determines the real wage firms can offer while maintaining their profit margins. If the economy is operating at a level of employment above the intersection point of these two relationships, what does this imply when plotting the corresponding point on a graph with inflation on the vertical axis and employment on the horizontal axis?
A macroeconomic model explains the relationship between unemployment and inflation using two underlying relationships in the labor market: an upward-sloping 'wage-setting' relationship and a horizontal 'price-setting' relationship. Arrange the following steps to correctly describe the causal chain that traces a point on the inflation-unemployment curve when the economy moves to a level of employment above the equilibrium where the two labor market relationships intersect.
Calculating Inflation from the Labor Market
In a standard graphical derivation from a labor market model, where an upward-sloping wage-setting relationship and a horizontal price-setting relationship are used to plot an inflation-employment curve, the resulting inflation-employment curve will have the same shape as the wage-setting relationship.
Impact of Structural Changes on the Inflation-Employment Relationship
A macroeconomic model derives an inflation-employment curve from a labor market model containing a wage-setting and a price-setting relationship. Match each concept from the labor market model to its direct consequence on the derived inflation-employment curve.
Deriving the Inflation-Employment Relationship
Consider a graphical model used to derive the relationship between inflation and employment. The model's starting point is a labor market graph with an upward-sloping 'wage-setting' relationship and a horizontal 'price-setting' relationship. The 'price-setting' relationship corresponds to a real wage index of 100. At an employment level of 97%, the 'wage-setting' relationship indicates a required real wage index of 103. Based on this information, what point is plotted on the corresponding inflation-employment graph?
Consider a labor market model represented on a graph with the real wage on the vertical axis and the level of employment on the horizontal axis. In this model, an upward-sloping 'wage-setting' (WS) curve intersects a horizontal 'price-setting' (PS) curve at an equilibrium point 'A'. At a higher level of employment, a point 'B' lies on the WS curve, vertically above the PS curve. Based on the graphical derivation method where the vertical gap between the WS and PS curves determines the inflation rate, which of the following accurately describes the corresponding inflation-employment curve?
In a graphical model where an inflation-employment curve is derived from a labor market model, if the level of employment is such that the real wage on the upward-sloping 'wage-setting' relationship is lower than the real wage on the horizontal 'price-setting' relationship, the resulting vertical gap corresponds to a rate of ______ on the inflation-employment curve.

Analyzing a Baseline Assumption in a Supply-Side Model
In the graphical derivation of the relationship between inflation and unemployment from a labor market model, the real wage at the initial equilibrium is conventionally set to an index value of 100. What is the primary purpose of this step?
Setting the initial real wage to an index value of 100 when graphically deriving the relationship between unemployment and inflation is a step based on a fundamental economic law rather than a methodological choice to establish a clear baseline.
Evaluating a Modeling Assumption
Critique of a Modeling Convention
In the process of graphically deriving the relationship between unemployment and inflation from a labor market model, the real wage at the initial equilibrium is set to an index value of 100. This is done not because of an underlying economic law, but to establish a clear ______ from which to measure subsequent percentage changes.
An economist is graphically illustrating the relationship between inflation and unemployment derived from a labor market model. Instead of following the convention of setting the initial equilibrium real wage to an index value of 100, they use the actual calculated real wage of $32.50. What is the primary analytical consequence of this decision?
In a graphical model used to derive the relationship between unemployment and inflation, an economist sets the real wage at the initial supply-side equilibrium to an index value of 100. If the economy then moves to a point where the real wage index is 97, what is the most accurate interpretation of this change?
