The example that provides the best defense for the unemployment and inflation tradeoff theory is that B. When inflation decreases, employers have more money to higher a larger percentage of the labor force, resulting in a decrease in unemployment.
Short-term trade-offs between unemployment and inflation must be made by society. Policymakers can reduce unemployment by increasing aggregate demand, but only at the expense of increased inflation. They can reduce inflation by reducing aggregate demand, but doing so will temporarily increase unemployment.
