Returns contracts incentivize accurate demand forecasting more effectively than rebate contracts.
Retailers are more motivated to invest in improving demand forecasts when they can return unsold inventory than when they receive rebates for sold items.
Management Science · 2009
Key Findings
- 01Returns contracts are superior to rebates contracts in incentivizing retailers to improve demand forecasting.
- 02Under rebate contracts, a retailer with inferior forecasting technology can sometimes benefit the entire system, which is not observed with returns contracts.
- 03The 'insurance' provided by returns contracts does not necessarily discourage forecasting; in fact, it leads to better outcomes.
Application
Design takeaway
When designing supply chain agreements, prioritize contract structures that directly incentivize accurate demand forecasting, such as product returns, over those that reward sales volume alone.
How to apply
When negotiating terms with suppliers or distributors, evaluate whether a returns policy or a rebate system would better drive the desired level of forecasting accuracy and inventory management.
Project actions
- 01When exploring supply chain strategies, consider the impact of different contractual agreements on information flow.
- 02Analyze how risk is distributed between partners in a supply chain and how this influences decision-making.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Provides a rigorous analytical framework for comparing contract types.
- +Offers counter-intuitive but well-supported conclusions about the effectiveness of returns.
Limitations
The simplified nature of the models might not reflect real-world complexities such as competition between retailers or fluctuating production costs.
Reliability & validity
The analytical nature of the study provides strong internal validity within its model. External validity depends on how well the model's assumptions map to real-world scenarios.
Think critically
Could there be situations where rebate contracts are preferable, perhaps due to manufacturer risk aversion or specific product characteristics?
Design Principles
"Incentivize desired behaviour by aligning contractual terms with the strategic goals of accurate information sharing and risk mitigation."
The choice of contractual agreement between manufacturers and retailers significantly impacts the accuracy of demand forecasting. This, in turn, affects inventory management, production planning, and overall supply chain efficiency.
What This Means for Your Design
It's better for a company to let stores send back unsold items than to just pay them for what they sell if you want them to guess demand more accurately.

Paragraph starter
Research by Taylor and Xiao (2009) in Management Science highlights that returns contracts are superior to rebate contracts in incentivizing retailers to improve demand forecasting accuracy. This suggests that when designing supply chain agreements, prioritizing mechanisms that allow for the return of unsold inventory can lead to more reliable demand information and better overall system performance compared to contracts solely focused on sales rebates.

- What were the main findings?
- Returns contracts are superior to rebates contracts in incentivizing retailers to improve demand forecasting.. Under rebate contracts, a retailer with inferior forecasting technology can sometimes benefit the entire system, which is not observed with returns contracts.. The 'insurance' provided by returns contracts does not necessarily discourage forecasting; in fact, it leads to better outcomes.
- What research method was used?
- Analytical modelling and game theory..
- How strong is the evidence?
- Evidence strength is rated Strong effect, based on a 2009 journal from Management Science.
- What should I do differently in my next project?
- When negotiating terms with suppliers or distributors, evaluate whether a returns policy or a rebate system would better drive the desired level of forecasting accuracy and inventory management.
- What are the limitations?
- The model assumes a 'newsvendor' retailer and a single manufacturer, and may not fully capture the complexities of multi-echelon supply chains or diverse market dynamics.
- Is there evidence that demand forecasting affects design outcomes?
- The study found that allowing retailers to return unsold products is a more effective strategy for encouraging accurate demand forecasting than offering rebates on sold products. This leads to better overall supply chain performance. The choice of contractual agreement between manufacturers and retailers significantly Source: Management Science (2009).
- Where does this accurate demand research apply?
- Supply chain management, specifically the relationship between manufacturers and retailers in industries with uncertain demand. It sits within commercial production research on designdex.org.
