For several decades, the orthodox economics approach to understanding choice under risk has been to assume that each individual person maximizes some sort of personal utility function defined over purchasing power. This new volume contests that even the best wisdom from the orthodox theory has not yet been able to do better than supposedly naïve models that use rules of thumb, or that focus on the consumption possibilities and economic constraints facing the individual.

The authors assert this by first revisiting the origins of orthodox theory. They then recount decades of failed attempts to obtain meaningful empirical validation or calibration of the theory. Estimated shapes and parameters of the "curves" have varied erratically from domain to domain (e.g., individual choice versus aggregate behavior), from context to context, from one elicitation mechanism to another, and even from the same individual at different time periods, sometimes just minutes apart.

This book proposes the return to a simpler sort of scientific theory of risky choice, one that focuses not upon unobservable curves but rather upon the potentially observable opportunities and constraints facing decision makers. It argues that such an opportunities-based model offers superior possibilities for scientific advancement. At the very least, linear utility – in the presence of constraints - is a useful bar for the "curved" alternatives to clear.

Experiments. Law. Economics. Those three words taken by themselves encompass vast parts of the human intellectual experience. Even when we link them together as Experimental Law and Economics, we see a large and diverse body of inquiry over the last half century. This 21st volume of Research in Experimental Economics focuses on experimental and empirical investigations into topics about both the economic effects of the law and how economic theories can explain the behavior of individuals within a legal system.

The papers in this volume follow two long-standing traditions. Firstly, the tradition of experimental methodology that allows one to test the potential impacts of alternate institutional arrangements. Secondly, a subset of the papers in this volume, in addition to exploring institutional change, follow the tradition in experimental economics of replication and robustness studies.

Illuminating three key areas, by summarizing mechanisms to facilitate the assembly of property rights, exploring legal procedure, and replicating classic market experiments using more recent experimental methods to understand how different market rules affect market outcomes, each of these papers contributes to one of the broader areas within experimental law and economics.
