This work aims to identify and quantify the biases behind the anomalous behavior of people when they deal with the Three Doors dilemma, which is a really simple but counterintuitive game. Carrying out an artefactual field experiment and proposing eight different treatments to isolate the anomalies, we provide new interesting experimental evidence on the reasons why subjects fail to take the optimal decision. According to the experimental results, we can quantify the size and the impact of three main biases that explain the anomalous behavior of participants: Bayesian updating, illusion of control, and status quo bias.

This study presents an analysis of hypothetical bias in WTA valuation connected with a bargaining game setting, in a field experiment context. The field of the experiment is the History Channel television "Pawn Stars". We collected a unique dataset that allowed us to analyze not only the gap between real and hypothetical WTA but also how they affect the bargaining game and vice versa. The general aim of this paper is to study the hypothetical bias related to subjects' WTA, and the factors that mostly affect it. The main results, of our paper, show that the hypothetical bias is positive, and it depends mainly on the price range and the type of good.
