Wrongful Conviction, Persuasion and Loss Aversion

When can a prosecutor persuade a loss-averse judge to increase her rate of conviction? Motivated by empirical evidence, I study a model of persuasion in which the loss a judge incurs from wrongful conviction looms larger than the gain from a just verdict. I show that, surprisingly, the prosecutor benefits from persuasion even when the judge is extremely loss-averse. However, a necessary condition is that the prosecutor does not underestimate the judge’s loss aversion. I draw on experimental findings to quantify the effectiveness of persuasion under loss aversion.
