Cheap, Easy, Or Connected: The Conditions For Creating Group Coordination, Mathew D. Mccubbins, Daniel Rodriguez, Nicholas Weller

In both legal and political settings there has been a push toward adopting institutions that encourage consensus. The key feature of these institutions is that they bring interested parties together to communicate with each other. Existing research about the success or failure of particular institutions is ambiguous. Therefore, we turn our attention to understanding the general conditions when consensus is achievable, and we test experimentally three crucial factors that affect a group's ability to achieve consensus: (1) the difficulty of the problem, (2) the costs of communication, and (3) the structure of communication. Using multiple experimental approaches, we find that …

The Theory Of Minds Within The Theory Of Games, Mathew D. Mccubbins, Mark Turner, Nicholas Weller

Classical rationality as accepted by game theory assumes that a human chooser in a given moment has consistent preferences and beliefs and that actions result consistently from those preferences and beliefs, and moreover that these preferences, beliefs, and actions remain the same across equal choice moments. Since, as is widely found in prior experiments, subjects do not follow the predictions of classical rationality, behavioral game theorists have assumed consistent deviations from classical rationality by assigning to subjects certain dispositions— risk preference, cognitive abilities, social norms, etc. All of these theories are fundamentally cognitive theories, making claims about how individual human …

Networks can affect a group’s ability to solve a coordination problem. We utilize laboratory experiments to study the conditions under which groups of subjects can solve coordination games. We investigate a variety of different network structures, and we also investigate coordination games with symmetric and asymmetric payoffs. Our results show that network connections facilitate coordination in both symmetric and asymmetric games. Most significantly, we find that increases in the number of network connections encourage coordination even when payoffs are highly asymmetric. These results shed light on the conditions that may facilitate coordination in real-world networks.

To address the neurocognitive mechanisms that underlie choices made after receiving information from an anonymous individual, reaction times (Experiment 1) and event-related brain potentials (Experiment 2) were recorded as participants played 3 variants of the Coin Toss game. In this game, participants guess the outcomes of unseen coin tosses after a person in another room (dubbed “the reporter”) observes the coin toss outcomes and then sends reports (which may or may not be truthful) to participants about whether the coins landed on heads or tails. Participants knew that the reporter's interests either were aligned with their own (Common Interests), opposed …
Nothing But The Truth? Experiments On Adversarial Competition, Expert Testimony, And Decision Making, Cheryl Boudreau, Mathew D. Mccubbins
Nothing But The Truth? Experiments On Adversarial Competition, Expert Testimony, And Decision Making, Cheryl Boudreau, Mathew D. Mccubbins

Many scholars debate whether a competition between experts in legal, political, or economic contexts elicits truthful information and, in turn, enables people to make informed decisions. Thus, we analyze experimentally the conditions under which competition between experts induces the experts to make truthful statements and enables jurors listening to these statements to improve their decisions. Our results demonstrate that, contrary to game theoretic predictions and contrary to critics of our adversarial legal system, competition induces enough truth telling to allow jurors to improve their decisions. Then, when we impose additional institutions (such as penalties for lying or the threat of …
