Take the following as truth: Figure 6 shows the curves for a situation where the discount and cross elasticities are zero, Figure 7 for when the discount elasticities are doubled, and Figure 8 for when the discount elasticities are doubled and the two no-shift elasticities are equal to -0.
Then the following statement: "Elasticities can be doubled as shown in figure 7." is true, false, or inconclusive?
Answer: True
