Competition
Developing an effective pricing strategy for Hoppiness also requires considering the prices for Bud. The best way to do this is by price comparisons.
Therefore, you define a new variable price.ratio indicating the ratio of PRICE.HOP to PRICE.BUD. You also take the log() to ensure that the price ratio of Hoppiness to Bud has the same magnitude as the price ratio of Bud to Hoppiness. To better understand the new price.ratio variable, you compare its values to the original PRICE.HOP and PRICE.BUD values.
