Answer:
a. short-run aggregate supply left.
Step-by-step explanation:
Aggregate Supply is the total quantity of goods & services, all the sellers in economy are planning to sell, in an economy during a period of time. Short Run Aggregate Supply is upward sloping, as supply is directly related to price level.
If there is future pessimism in economy; due to corporate scandal, international tensions, and loss of confidence in policymakers. Then, producers will be apprehensive about their products sale, will also feel price vulnerable. This would imply that the short run aggregate supply would decrease, the SRAS curve would shift leftwards.
