Dominant Smart Contracts Based on Major Bargaining Solutions
We consider a situation in which two parties have concluded an efficient contract corresponding to one major bargaining solution. After the parties have agreed on one particular contract, an unanticipated shock may change the contract outcomes in a way that benefits one party but harms the other party. If this happens, they have the option to either stay with the original exchange contract or adjust some contract parameters such as the price. We …
Confidence and Outcome Expectations in Bilateral Negotiations–A Dynamic Model
This work proposes and studies a dynamic model of two bargaining parties exchanging offers over time, considering their confidence about the share of the “pie” they obtain, which translates into expectations regarding the outcome of the bargaining process. The model predicts the sequence of offers as well as the final agreement for given confidence parameters. A mathematical analysis of the model shows the outcome is an Asymmetric Nash Bargaining…
Two-Person Fair Division with Additive Valuations
In the literature, many desirable properties for allocations of indivisible goods have been proposed, including envy-freeness, Pareto optimality, and maximization of either the total welfare of all agents, the welfare of the worst-off agent, or the Nash product of agents’ welfares. In the two-person context, we study relationships among these properties using both analytical models and simulation in a setting where individual preferences are give…

Two-party Bargaining Processes Based on Subjective Expectations
This work presents a model for a two-party bargaining process in which multiple offers are exchanged as the negotiation goes on, under a risk of breakdown. Typical game theoretical analyses of such settings assume the breakdown risk is known and the parties are able to calculate an initial offer that is immediately accepted by the other party, ending the negotiation. Aiming to develop a model that is closer to real-life situations, in which parti…
Testing Fairness Principles for Public Environmental Infrastructure Decisions
Public infrastructure decisions affect many stakeholders with various benefits and costs. For public decisions, it is crucial that decision-making processes and outcomes are fair. Fairness concepts have rarely been explored in public infrastructure planning. We close this gap for a global issue of growing importance: replacing sewer-based, centralized by decentralized wastewater systems. We empirically study fairness principles in this policy-rel…
Is there more than one ratio bias? If so, why
The ratio bias refers to decision makers' propensity to overestimate probabilities that are specified as ratios of large numbers in comparison to a ratio of smaller numbers (e.g., 9:100 vs. 1:10). To reconcile conflicting findings about this bias, we study such deviations in a more general setting allowing for deviations in both directions, irrational indifference, and inability to decide. We find that the predominant direction of deviations depe…

National Cultural Differences in the Use and Perception of Internet-based NSS
In this article, we apply an extended technology acceptance model (TAM) to explore whether national culture influences a user's perception and use of Internet-based negotiation support systems (NSS). In particular, we are interested in whether different preferences for communication patterns, as we find them for low-context and high-context cultures, influence the use and perception of different NSS support tools. The Web-based system Inspire, wh…
