Pricing Decision — Technical Summary
1. Purpose
The difficulty of pricing under uncertainty is not estimating demand, but deciding which price can be safely deployed.
Prices that maximize expected profit often expose unacceptable downside risk, leading to reversals, overrides, and erosion of trust in pricing decisions.
This system addresses the technical question:
How should prices be selected when profit distributions—not point estimates—matter?
2. Data Basis
Two operating modes are supported:
Synthetic Mode
- controlled elasticity parameter
- additive demand noise
- known cost structure
- fully reproducible
Used to demonstrate idealized pricing behavior.
Observational Retail Mode (UCI, local only)
- transactional retail data
- time-varying prices
- non-randomized price changes
- aggregated per period
Elasticity estimates in this mode are observational, not causal.
3. Model Structure
Demand is modeled using a log–log specification. Parameter uncertainty is captured via bootstrap resampling.
The objective is distributional robustness, not causal identification.
4. Profit Evaluation
For each candidate price:
- profit distributions are computed
- median profit represents expected outcome
- downside quantiles (q10 or q5) represent risk exposure
All profit values are expressed per aggregation period.
5. Decision Logic
Candidate prices are evaluated within a constrained grid around the current median price.
Decisions follow explicit governance rules:
- Feasibility: at least one price must yield positive median and downside profit
- Leverage: price must materially affect profit
- Risk: downside exposure must remain within relative and absolute caps
Violations trigger HOLD or NO-GO outcomes.
6. Output
The system produces:
- decision state (OPTIMIZE / HOLD / NO-GO)
- recommended deploy price
- profit distribution diagnostics
- traceable justification metrics
This design prioritizes auditability, explainability, and governance over model complexity.
Closing Position
Pricing under uncertainty is a decision problem, not a curve-fitting exercise.
This system converts uncertain demand response into deployable pricing actions that remain defensible under review, volatility, and downside exposure.
