A fооd delivery plаtfоrm аllows а small group of restaurants to offer a “Free Dessert with Every Order” promotion as a pilot test. These restaurants experience a significant increase in order volume compared to other restaurants on the platform. Based on these results, the platform decides to roll out the promotion to all restaurants. Explain why a market effect might lead to a much smaller increase in order volume when the promotion is implemented across all restaurants. Is this an internal or external validity issue? Hint: Consider how scale might change the competitive landscape. If it is an internal validity issue, explain why the estimated effect is biased. If it is an external validity issue, explain why the results may not be generalizable.
