A typical profit-maximizizng firm in a perfectly competitive constant-cost industry is earning a positive economic profit. a) is the market price greater than, less than, or equal to the firm's price? explan.
the market price is equal to the firms price because in a perfecly competitive market, firms are price takers
State what will happen to the market equilibrium price and quantity of corn in the long run. explain.
the market quantity will increase and price will decrease. new farmers will enter the market which increases the market supply curve
Soybeans are produced in a perfectly competitive market. Assume farmers can grow wither corn or soybeans on the same land. What happens to the price of soybeans in the next planting season if the price of corn increases? Explain
the price of sybeans will increase because if more corn farmers (suppliers) enter the market than there will not be as many producing soybeans. there for soybean price increases.

Now suppose the market is in long-run equilibrium. The government gives a lump-sum subsidy to each firm producing in the industry. Indicate whether each of the following will increase, decrease, or remain the same. (ii) The market price and quantity in the long run. Explain.
