Answer:
a. negative cost-push inflation
b. Phillips Curve will shift right
Explanation:
a. Cost push inflation occurs when the costs of inputs such as wages and material costs increases. This leads to an increase in prices because producers will have to increase prices to make a profit.
In this scenario, material prices dropped instead of increasing. A negative cost-push inflation will therefore happen.
b. This will lead to a shift right in the Phillips curve to reflect that inflation has fallen. It will increase the output gap between Potential and Actual GDP because a lower inflation means more unemployment which means the economy is shrinking.
