Research question
How do 90-ending prices function as psychological price endings in retail markets?
Data
The study analyzes more than 107 million retail-price observations from 104 food stores.
Main finding
- The public abstract reports that 90-ending prices are approximately 54% higher on average than comparable non-90-ending prices.
Interpretation and limits
The reported difference is an association. It should not be interpreted as evidence that the price ending causes higher prices or as proof of consumer deception.
