Shifts in the WS and PS Curves

Interpreting Labor Market Equilibrium

An economy's labor market is described by a wage-setting (WS) and price-setting (PS) model. For the past decade, the unemployment rate has fluctuated between 4% and 6%, but has averaged 5%. The intersection of the current WS and PS curves also indicates an equilibrium unemployment rate of 5%. Which of the following statements provides the best interpretation of this situation?

In an economy described by the wage-setting and price-setting model, the actual observed unemployment rate will consistently and precisely match the equilibrium unemployment rate determined by the intersection of the two curves at all points in time, assuming the underlying determinants of the curves are stable.
