In the mid-twentieth century, economist A.W. Phillips identified a persistent inverse relationship between unemployment and inflation, suggesting that efforts to reduce joblessness tended to accelerate price increases. This empirical observation, later formalized as the Phillips Curve, appeared to provide policymakers with a manageable tradeoff: lower unemployment could be achieved at the expense of higher inflation, and vice versa. During the 1960s, this framework gained wide acceptance, informing expansionary fiscal and monetary strategies across several advanced economies.
The phenomenon of stagflation in the 1970s- when high inflation coexisted with high unemployment- posed a direct challenge to this view. Economists such as Milton Friedman and Edmund Phelps argued that the original formulation neglected the role of expectations. If households and firms come to anticipate inflation, they adjust wages and prices accordingly, negating any sustained employment gains from expansionary policy. The oil shocks of that decade, which sharply increased production costs across industries, further illustrated how supply-side disturbances could simultaneously drive inflation and unemployment, undermining the presumed stability of the curve. Consequently, the tradeoff between inflation and unemployment was understood to exist only in the short run.
Subsequent research has sought to reconcile these insights by incorporating expectations, productivity trends, and supply shocks into a more dynamic model. The modern interpretation treats the Phillips Curve not as a stable empirical law but as a conditional relationship whose slope and position shift over time. Thus, while the curve remains conceptually significant, its predictive and policy relevance have diminished as economists recognize the economy’s adaptive complexity.
Based on the passage, which of the following would a government that accepted the Phillips Curve framework in the 1960s most likely have done?
A. Maintained a fixed monetary supply to prevent expectations of inflation from developing
B. Anticipated an increase in unemployment levels as a result of increase in inflation levels
C. Allowed inflation to rise temporarily, believing it would keep output from falling and unemployment from climbing later.
D. Lowered interest rates even at the risk of higher inflation to reduce unemployment
E. Incorporated household and business expectations, productivity trends, and supply shocks to create a rounded fiscal policy
