Equilibrium Discovery and Preopening Mechanisms in an Experimental Market

We experimentally analyze equilibrium discovery in i) a pure call auction, ii) a call auction preceded by a nonbinding preopening period, and iii) a call auction preceded by a binding preopening period. We examine whether a preopening period can facilitate coordination on the Pareto dominant equilibrium. During the nonbinding preopening period, traders tend to place manipulative orders. After observing such orders, participants learn to distrust cheap talk and coordinate less on Pareto dominant outcomes. In contrast, we find that, when preopening orders are binding, they improve the ability to coordinate on high gains from trade.

Non-exclusive contracts, collateralized trade, and a theory of an exchange

Liquid markets where agents have limited capacity to sign exclusive contracts may permit agents to promise the same asset to multiple counterparties and subsequently default. I show that in such markets an exchange can arise as an intermediary whose only role is to set limits on the number of contracts that agents can report voluntarily. In some cases, these limits must be non-binding in equilibrium, and reported trades must not be made public. A (costly) alternative to an exchange is collateralized trade, and the gains from an exchange increase when agents have more intangible capital (e.g., reputation) or when markets are more liquid. ; Superseded by Working Paper 10-28R: Inducing agents to report hidden trades: a theory of an intermediary.Contracts ; Trade

Nonbinding Suggestions: The Relative Effects of Focal Points versus Uncertainty Reduction on Bargaining Outcomes

This paper focuses on the effects of nonbinding recommendations on bargaining outcomes. Recommendations are theorized to have two effects: they can create a focal point for final bargaining positions, and they can decrease outcome uncertainty should dispute persist. While the focal point effect may help lower dispute rates, the uncertainty reduction effect is predicted to do the opposite for risk-averse bargainers. Which of these effects dominates is of critical importance in the optimal design of alternative dispute resolution (ADR) procedures, which are becoming increasingly utilized to help resolve disputes in a variety of settings. We theoretically examine the effects of recommendations on the bargaining contract zone. Our theoretical framework, which allows bargainers’ final positions to influence a binding outcome should negotiations fail, provides for a more stringent test of focal points than previously considered. We also present data from controlled laboratory bargaining experiments that are consistent with our model of recommendation effects. Recommendations are empirically shown to influence final bargaining positions and negotiated settlement values. Furthermore, dispute rates are significantly lower when one includes recommendations, even where the recommendation is completely ignored in final-stage arbitration. This highlights a potentially significant role for the use of nonbinding procedures, such as mediation, as a preliminary stage in developing more efficient ADR procedures.

Non-binding signals: are they effective or ineffectual?

Companies often send non-binding messages to their competitors, to consumers, to channel members and to various other recipients. When such messages are in the form of price signals, they tend to make antitrust authorities uneasy since it is widely believed that price signaling can and does serve as a collusion facilitating mechanism. We conducted experimental posted-offer markets with multiple competitive equilibria, and found that contrary to expectations, markets in which sellers could engage in cheap talk had lower contract prices than markets without cheap talk opportunities.posted-offer markets

Lawyers in the Shadow of the Regulatory State: Transnational Governance on Business and Human Rights

Lawyers are beginning to play an important role in strengthening the system of transnational governance that regulates business and human rights. In setting the background to our discussion of lawyers’ role in this context, Part I of this Article provides a general overview of the emergence of the transnational governance regime. Part II then describes some of the governance instruments that attempt to prevent and rectify the adverse human rights impacts of business activities. Part III discusses the extent to which lawyers are advising their business clients on human rights issues, the factors that may inhibit or encourage the provision of such advice, and how the lawyers who are raising these issues are framing these discussions with their clients. Finally, Part IV suggests further areas of inquiry that may enrich our understanding of the role that lawyers can play in helping construct a transnational governance regime on business and human rights

Nonbinding Voting for Shareholder Proposals

Shareholder proposals are a common form of shareholder activism. Voting for shareholder proposals, however, is nonbinding since management has the authority to reject the proposal even if it received majority support from shareholders. We analyze whether nonbinding voting is an effective mechanism for conveying shareholder expectations. We show that, unlike binding voting, nonbinding voting generally fails to convey shareholder views when manager and shareholder interests are not aligned. Surprisingly, the presence of an activist investor who can discipline the manager may enhance the advisory role of nonbinding voting only if conflicts of interest between shareholders and the activist are substantial

COORDINATING COLLECTIVE RESISTANCE THROUGH COMMUNICATION AND REPEATED INTERACTION

This paper presents a laboratory collective resistance (CR) game to study how different forms of repeated interactions, with and without communication, can help coordinate subordinates' collective resistance to a ???divide-and-conquer??? transgression against their personal interests. In the one-shot CR game, a first???mover (the ???leader???) decides whether to transgress against two responders. Successful transgression increases the payoff of the leader at the expense of the victim(s) of transgression. The two responders then simultaneously decide whether to challenge the leader. The subordinates face a coordination problem in that their challenge against the leader's transgression will only succeed if both of them incur the cost to do so. The outcome without transgression can occur in equilibrium with standard money-maximizing preferences with repeated interactions, but this outcome is not an equilibrium with standard preferences when adding non-binding subordinate ???cheap talk??? communication in the one-shot game. Nevertheless, we find that communication (in the one-shot game) is at least as effective as repetition (with no communication) in reducing the transgression rate. Moreover, communication is better than repetition in coordinating resistance, because it makes it easier for subordinates to identify others who have social preferences and are willing to incur the cost to punish a violation of social norms.Communication, Cheap Talk, Collective Resistance, Divide-and-Conquer, Laboratory Experiment, Repeated Games, Social Preferences

How do coalitions get built - Evidence from an extensive form coalition game with renegotiation & externalities

We investigate a three-person coalition game in which one bargainer, the builder, can propose and build a coalition over two stages. In equilibrium, coalition building ends with an efficient grand coalition, while the equilibrium path is contingent on the values of the two-person coalitions and associated externality payoffs. Considering relative payoffs need not change the equilibrium path. Nevertheless, outcomes in the experiment are often inefficient. One explanation is that bargainers have difficulties anticipating the future actions of other bargainers. This problem might be mitigated by allowing bargainers to communicate prior to each stage. A test finds that communication does in fact increase efficiency, although unevenly, and at the cost of the builder. The study implies that the nature and pattern of communication among bargainers is a critical factor in efficient coalition building.coalitional bargaining, communication, game theory, experiment
