Exercise 3: Base Price Elasticity

Title Top

Exercise: Identifying Incorrect Elasticities You have been provided with a list of elasticity values from the FMCG sector. Your task is to identify which of these values do not make sense based on what you know about typical elasticity ranges.

Promo Price Elasticity Values:

  • -0.9: Reasonable, indicating moderate elasticity.
  • -1.8: Reasonable, suggesting high elasticity.
  • -3.0: Unusual, as it indicates extremely high elasticity; promo price elasticity rarely exceeds -2.
  • 1.5: Incorrect, as elasticity should be negative, reflecting the inverse relationship between price and demand.
  • -0.6: Reasonable, indicating moderate elasticity.

Base Price Elasticity Values:

  • -0.5: Reasonable, indicating inelastic demand.
  • -1.3: Reasonable, indicating elastic demand.
  • -2.5: Unusual, as it suggests very high elasticity; typically, base price elasticity ranges between -1 and -2.
  • -0.8: Reasonable, indicating inelastic demand.
  • 0.2: Incorrect, as elasticity should be negative, reflecting the inverse relationship between price and demand

Answer: The baseline is too high in the black quadrant; it should align more closely with sales when no promotion is played.

Answer: At the end of the scope, the baseline should decrease more rapidly to zero. This is a common issue encountered when reviewing the modeled baseline, and you should coordinate with your Data Analyst to address and resolve it.

Answer: The baseline is incorrectly following sales as if no promotion is occurring, which should not be the case. You need to inform your Data Analyst to address this issue.
