In the past few decades, economic analysis of law has been challenged by a growing body of experimental and empirical studies that attest to prevalent and systematic deviations from the assumptions of economic rationality. While the findings on bounded rationality and heuristics and biases were...

Building on Kahneman and Tversky's Prospect Theory, this paper presents a series of experiments designed to reveal people's preferences regarding attorneys' fees. Contrary to common economic wisdom, it demonstrates that loss aversion (rather than risk aversion or incentivizing the lawyer to win...

This is the first chapter of a forthcoming book. It provides a systematic, up-to-date overview of the psychological phenomenon of loss aversion (LA), including a brief historical account, description of Prospect Theory and its critique, empirical evidence of LA, and the role of emotions in LA....

Welfare economics—the normative branch of economics—is a consequentialist moral theory. Unlike deontological morality, at least in its basic form it attributes no intrinsic value to prohibitions on active or intentional harming of other people, lying, or promise breaking, and does not allow...
