Figure 6
The vertical axis is labeled “Bacterial Cross-Resistance (phi)” and ranges from 0 to 2 with increments of 0.2. The horizontal axis is labeled “Entry Costs (R)” and ranges from 0 to approximately 6 with increments of 1. A solid downward sloping curve starts near the top left, around phi equals 2 and R equals 0.8, and decreases toward the point near R equals approximately 3.6 and phi equals 1. From this point, a vertical line drops straight down to the horizontal axis at approximately R equals 3.6. A dashed curve starts just to the right of the solid curve and decreases linearly to the horizontal axis just to the right of 6.5. Both curves intersect at (3.6, 1). The graph is divided into regions labeled directly on the plot. The region to the left of the solid curve is labeled “accommodation”. The region to the right of the dashed curve is labeled “blocked entry”. The region between both curves, above the intersection point, is labeled “deterrence - incumbent overproduces”. The region between both curves, below the intersection point, is labeled “deterrence - incumbent underproduces”. A text box in the upper right lists parameter values: “alpha equals 10”, “theta equals 2”, “beta equals 2”, and “c equals 2”. All numerical values are approximated.Effects of bacterial cross-resistance and entry costs on incumbent’s optimal strategy. Source(s): Figure by author
