Mind Your Margins: Lessons From Behavioral Economics
Price reductions are a frequent tactic to increase sales and, hopefully, profit. Whether the price reduction increases profit depends on just how much unit sales increase. M anagers often use a mental shortcut, believing sales must increase by the same percentage as the price reduction in order to maintain the same level of gross profit. That is, many managers would intuitively respond that a 10% price reduction requires a 10% increase in unit sales to maintain the same level of gross profit. This is incorrect. A small reduction in price can dra ma tically reduce the unit margin. T he unit sales increase needed to maintain the same level of profit is often much larger than expected. This error is explained by several cognitive processes identified by behavioral economics. A. Base-rate neglect causes decision-makers to focus on the percentage change in price while ignoring the “base” of the original margin (Tversky & Kahneman, 1974). B. A ttribute substitution lead...
