Why Equivalent Metrics Lead to Different Decisions

Managers rely on efficiency metrics to guide decisions across marketing, finance, and strategy, yet seemingly equivalent metrics can produce dramatically different judgments and choices.


This webinar explores new research showing how reciprocal efficiency ratios, such as ROAS (return on advertising spend) versus ACOS (advertising cost of sales), systematically influence willingness to incur costs, despite conveying mathematically identical information. More broadly, the session examines how the framing of quantitative information, including percentages versus dollar amounts, shapes managerial and consumer decision-making across contexts.


Attendees will gain insights into the psychology of metrics and learn how measurement and presentation choices can subtly influence business decisions, resource allocation, and strategic outcomes.
