Proponents of rational expectations theory argued that, in the most extreme case, if policymakers are credibly committed to reducing inflation and rational people understand that commitment and quickly lower their inflation expectations, the sacrifice ratio could be as small as_____________

The Sacrifice Rate is the loss of output due to the fight against inflation, and can be expressed as how much product is lost to reduce inflation by 1 percentage point.

Therefore, the social cost of fighting inflation is a reduction in GDP and an increase in the unemployment rate.
