Answer:
1) supply will decrease
Step-by-step explanation:
When both supplier and consumer expectations change because a price change is anticipated, their supply and demand curves shift.
When suppliers expect an increase in the price of key inputs, the supply curve will shift to the left, reducing the quantity supplied ad every price level. Inversely, when consumers expect an increase in future prices, the current demand curve will shift to the right, increasing the quantity demanded at every price level.
Both shifts in the supply curve and demand curve have one thing in common, they will increase the equilibrium price.
