Answer:
For tax: Increases equilibrium price
II. Reduces equilibrium quantity
For subsidy: Reduces equilibrium price
Increases equilibrium quantity
Explanation:
Tax increases the price of a good or service or cost of production which makes the good more expensive. This discourages demand / supply and demand or supply falls. This leads to a fall in equilibrium quantity.
A subsidy is an amount given by the government to encourage production or consumption of a certain good. Subsidy given to producers reduces the cost of production, makes equilibrium price fall and encourages supply. This leads to an increase in supply so equilibrium quantity rises.
