Consider panel (b) of Figure 25-5, in which the ATC curve and associated data are the same-drawn at a slightly different scale, however-as in Figure 25-4. Suppose that the shape of the demand curve faced by the firm in panel (b) changes in such a way that it becomes tangent to the ATC curve at a price of $5 per unit. What will happen to this firm's long-run output rate and economic profits as a result?
