How do the equilibrium price and the quantity of a commodity change when the price of input used in its production changes?
The change in the price of input price of input alters the cost of production of a commodity. Let us analyze the two different cases.
1. Increase in input price If the input price of a firm increases, the cost of production will also increase which will discourage the firm’s incentive to produce and supply the commodity. This will lead to a left upward shift of the marginal cost curve which further will lead to a leftward parallel shift of an individual firms supply curve and finally a leftward shift of the market supply curve. The demand curve remaining the same, the new equilibrium will occur at E2 with higher equilibrium price (P2) and lower quantity of output (q2).
2. Decrease in input price If an input price of a firm decreases, then the cost of production will also decrease. This will shift the marginal cost curve rightward, which implies that the firms supply curve will also shift rightward. Consequently, the market supply curve will shift rightward parallelly from S1S1 to S2S2. Demand curve remaining the same, the new equilibrium will occur at E2 with lower equilibrium price (P2) and higher quantity level of output (q2).

Suppose the price at which the equilibrium is attained in exercise 5 is above the minimum average cost of the firms constituting the market. Now if we allow for free entry and exit of firms, how will the market price adjust to it?
When do we say that there is an excess demand for a commodity in the market?
