Consider the following "informational robustness" question: what can we say about the set of outcomes that may arise in equilibrium of a Bayesian game if players may observe some additional information? This set of outcomes will correspond to a solution concept that is weaker than equilibrium,...

We propose an incomplete information analogue of rationalizability. An action is said to be belief-free rationalizable if it survives the following iterated deletion process. At each stage, we delete actions for a type of a player that are not a best response to some conjecture that puts weight...

Recently a variety of link-based stability concepts have emerged in the literature on game theoretic models of social network formation. We investigate two basic formation properties that establish equivalence between some well known types of stable networks and their natural extensions. These...

Using language game notions and the equivalence between games, this document studies John Nash's decision of not playing the coalitional game proposed by John von Neumann. The key point is that Nash suggested hypothetical worlds that are incompatible with the kind proposed by von Neumann. And,...

The ultimatum heuristic is a decision-making tendency discernible in graphical plots of mixed-motive noncooperative games. As such, it can serve also as a solution approach, backsolving, predicting and explaining outcomes better than the mainstay Nash equilibrium concept whenever data for the...

In Hawk-Dove games with mulitiplicity of equilibria, we study which equilibria are selected using various equilibrium selection methods. Using a uniform price auction as an illustrative example, we apply the tracing procedure method of Harsanyi and Selten (1988), the robustness to strategic...

We consider a two-stage serial supply chain with capacity limits, where each installation is operated by managers attempting to minimize their own costs. A multiple-period model is necessitated by the multiple stages, capacity limits, stochastic demand, and the explicit consideration of...

This paper creates a game theoretic model to determine how pendulum arbitration or baseball arbitration impacts the incentives of litigants. Pendulum arbitration is when both parties submit competing proposals and the arbitrator chooses only one of the bids, in its entirety, to be binding on...

This research addresses incentive principles that drive information sharing and affect database value. Many real world centralization and standardization efforts have failed, typically because departments lacked incentives or needed greater local autonomy. While intangible factors such as...

Zero-Knowledge Proof-of-Identity from trusted public certificates (e.g., national identity cards and/or ePassports; eSIM) is introduced here to permissionless blockchains in order to remove the inefficiencies of Sybil-resistant mechanisms such as Proof-of-Work (i.e., high energy and...
