The following graph shows its demand curve, marginal revenue (MR) curve, marginal cost (MC) curve, and average total cost (ATC) curve. Place a black point (plus symbol) on the graph to indicate the long-run monopolistically competitive equilibrium price and quantity for this firm.

The graph below shows the demand curve for a perfectly competitive firm. Suppose that firms in this industry discover a way to differentiate their products. Using the line drawing tool, show how the firm's demand curve would be likely to change. Label the new demand curve 'd,'. Carefully follow the instructions above, and only draw the required objects. Since the demand curve is downward sloping, the monopolistically competitive firm will set a price OA. that is less than marginal cost. B. that is unrelated to marginal cost. OC. that is equal to marginal cost. D. that is greater than marginal cost. Price 10- Q Q Output 10

Consider the model with monopolistic competition and full symmetry between the firms (internal returns to scale) in a single integrated market. Now assume that a new technology becomes available that reduces a firm's marginal cost of production by a given amount but requires a larger fixed-cost investment to implement. Suppose that all fırms adopt the new technology. How does this impact the equilibrium number of varieties and the equilibrium price? Show your work. Edit View Insert Format Tools Table
