A graph plots price and cost (dollars per unit) versus Quantity (units per week). In the graph, the horizontal axis ranges from 0 to 24 with an increment of 4 units. The vertical axis ranges from 0 to 25 with an increment of 5 units. The graph plots two slopes, two convex curves, and four closed points (4, 4), (8, 5), (8, 15), and (16, 10). The first slopes fall through (0, 25) to (10, 0) is labeled M R, and the second slope falls through (0, 25) to (20, 0) is labeled D. The first curve falls through (2, 5) to (4, 4) then rises through (8, 5) to (24, 18) is labeled M C and the second curve falls through (3, 25) to (16, 10) then rises through (20, 11) to (24, 15) is labeled A T C.

A graph plots price (dollars per jacket) versus Quantity (jacket per day). In the graph, the horizontal axis ranges from 0 to 400 with an increment of 80 units. The vertical axis ranges from 0 to 180 with an increment of 20 units. The graph plots two slopes, two convex curves, and a closed point (200, 78). The first slopes fall through (0, 120) to (400, 30) is labeled M R, and the second slope falls through (0, 120) to (400, 70) is labeled D. The first curve falls through (20, 70) to (80, 50) then rises through (160, 60) to (300, 170) is labeled M C and the second curve falls through (130, 160) to (280, 130) then rises through (320, 135) to (400, 160) is labeled A T C.

A graph plots price and cost (dollars per unit) versus Quantity (units per week). The graph points plotted on the x-axis are 100, 140, 200, 220, and 250. The vertical axis ranges from 0 to 100 with an increment of 10 units. The graph plots two convex curves, four falling curves, and six closed points (100, 70), (140, 55), (200, 80), (200, 100), (220, 90), and (250, 85). The first curve falls through (10, 35) to (40, 30) then rises through (100, 40) to (250, 100) is labeled M C, and the second curve falls through (95, 50) to (150, 55) then rises through (200, 65) to (250, 85) is labeled A T C. The first curve falls through (30, 78) to (160, 25) is labeled M R sub 2. The second curve that falls through (50, 95) to (190, 40) is labeled D sub 2. The third curve that falls through (150, 100) to (250, 70) is labeled M R sub 1. The fourth curve falls through (200, 100) to (250, 85) is labeled D sub 1.

Which of the following events occurs when one firm in monopolistic competition produces a new and improved product?

Product development is efficient if the marginal social cost of a new and improved product ________ its marginal social benefit. In monopolistic competition marginal revenue is less than price, so product development is probably ________ to its efficient level.
