Price Elasticity of Demand : Framework to determine scalable and robust price elasticity model with large variety of price range

Pricing strategy is an important facet for pricing managers in retail. An optimal price quote of items in store keeps balance between revenue and customer satisfaction level in the business. One of the critical factors in building an effective pricing strategy is to understand the responsiveness of demand to price changes, referred to as Price Elasticity of Demand.

Apart from price, additional factors like promotion, holidays, weather etc also impact the demand. Sometimes, we can observe different price-demand relationship for diverse geolocation features. Another important distinguishing driver for price elasticity is price ranges of items inside a specific item hierarchy. In such cases, it is effective to build different price elasticity model frameworks for different segments of price fluctuations.

The aim of this talk will be to show how an efficient machine learning model is built to determine item-location level price elasticity. Topics include:

  1. Regularized linear models are built on demand considering relevant external factor along with price of items.
  2. Parallel computation is applied to make the solution more time efficient.
  3. Parameters for the model are trained separately for items belonging to different price range clusters.
  4. Finally conclude with how this robust and scalable method has improved forecasting accuracy and can be used as a foundational solution for any market and domain.
