Start from the beginning. Assume that this is a constant-cost industry. Suppose that the demand for this product decreases by 1,200 units and stays at this new lower level for ever. Then, in the short run, the equilibrium price of the product will equal there will be dollars per unit, the equilibrium quantity units, and firms in the industry each making an economic profit of dollars. Then, in the long run, the equilibrium price of the product will equal dollars per unit, the equilibrium quantity units, and there will be firms in the industry each making an economic profit of dollars.
