"For business economists, this book offers important insight into the use of experiments for organizations and their leadership. The benefits of experiments to an organization are the ability to test ideas, understand tradeoffs, and evaluate existing products and procedures. Experiments can also be a tool for discovery, with or without a theory to test. Leadership can use experiments to learn what they do not know, then adapt and grow their organizations with informed decisions."

“'The Power of Experiments' is a terrific overview of how organizations, especially online companies but also government and other groups, can use A/B testing to optimize their results. Luca and Bazerman also discuss issues of ethics and consent that affect these efforts, perhaps limiting what some parties can or should do...an excellent book for managers and executives who oversee online marketing or other behavioral elements of an operation. While most professional marketers will be familiar with the concepts and examples presented in the book, Luca and Bazerman's easy style and approachable writing provide an excellent introduction or refresher for non-specialists at all levels. Highly recommended.”
