A landmark practical guide from the twenty-first-century pioneer in economics. Experimental economics—generating and interpreting data to understand human decisions, motivations, and outcomes—is today all but synonymous with economics as a discipline. The advantages of the experimental method for understanding causal effects make it the gold standard for an increasingly empirical field. But until now the discipline has lacked comprehensive and definitive guidance for how to optimally design and conduct economic experiments. For more than 30 years, John A. List has been at the forefront of using experiments to advance economic knowledge, expanding the domain of economic experiments from the lab to the real-world. Experimental Economics is his A-to-Z compendium for students and researchers on the ground floor of designing, conducting, analyzing, and interpreting data that they generate. List seeks not only to guide readers on how to develop and implement their experimental projects—everything from design to administrative and ethical considerations—but to help them avoid all the mistakes he’s made in his career, too. Experimental Economics codifies its author’s refined approach to the design, execution, and analysis of laboratory and field experiments. It is a milestone work poised to become the definitive reference for the next century of economics (and economists).
