Temporary vs. Permanent Trade-off in the Phillips Curve

US Economic Data (1966 onwards) as Evidence for a Shifting Phillips Curve

Friedman's Argument: How Adaptive Expectations Fuel Accelerating Inflation

A country's policymakers successfully use economic stimulus to keep the unemployment rate below its long-run sustainable level for several consecutive years. According to the economic theory that argues the inverse relationship between unemployment and inflation is only a short-term phenomenon, what is the most likely outcome for the inflation rate during this period?

Policy Dilemma and Inflation Expectations

The Dynamics of Inflation Expectations

According to the economic theory that challenges the stability of the unemployment-inflation trade-off, a government can permanently maintain a lower-than-natural rate of unemployment as long as it is willing to accept a consistently high, but stable, rate of inflation.

A government implements policies to maintain an unemployment rate below the level consistent with stable prices. According to the theory that challenges the long-run stability of the inflation-unemployment trade-off, this leads to accelerating inflation. Arrange the following events in the causal sequence that explains this phenomenon.

The Disappearing Trade-off

An economic theory suggests that the trade-off between inflation and unemployment is not stable. Match each component of this theory with its correct description.

According to the economic theory that challenges the long-run stability of the unemployment-inflation trade-off, the trade-off itself will disappear if policymakers attempt to maintain unemployment below its sustainable rate for an extended period. The theory posits that this happens because the entire curve representing the trade-off shifts upward, driven by changes in ____.
