If players do not ob- serve the strategies chosen by their opponents (as in extensive-form games), then learning is consistent with steady states that are not Nash equilibria because players can maintain incorrect beliefs about off-path play. Beliefs can also be incorrect because of cogni- tive limitations and systematic inferential errors. -

Modeling Strategic Behavior1
Modeling Strategic Behavior1 A Graduate Introduction to Game Theory and Mechanism Design George J. Mailath Department of Economics, University of Pennsylvania Research School of Economics, Australian National University 1September 16, 2020, copyright by George J. Mailath. World Scientific Press published the November 02, 2018 version. Any significant correc- tions or changes are listed at the back. To Loretta Preface These notes are based on my lecture notes for Economics 703, a first-year graduate course that I have been teaching at the Eco- nomics Department, University of Pennsylvania, for many years. It is impossible to understand modern economics without knowl- edge of the basic tools of game theory and mechanism design. My goal in the course (and this book) is to teach those basic tools so that students can understand and appreciate the corpus of modern economic thought, and so contribute to it. A key theme in the course is the interplay between the formal development of the tools and their use in applications. At the same time, extensions of the results that are beyond the course, but im- portant for context are (briefly) discussed. While I provide more background verbally on many of the exam- ples, I assume that students have seen some undergraduate game theory (such as covered in Osborne, 2004, Tadelis, 2013, and Wat- son, 2013). In addition, some exposure to intermediate microeco- nomics and decision making under uncertainty is helpful. Since these are lecture notes for an introductory course, I have not tried to attribute every result or model described. The result is a somewhat random pattern of citations and references. -
Comparing Auction Designs Where Suppliers Have Uncertain Costs and Uncertain Pivotal Status
RAND Journal of Economics Vol. 00, No. 0, Winter 2018 pp. 1–33 Comparing auction designs where suppliers have uncertain costs and uncertain pivotal status ∗ Par¨ Holmberg and ∗∗ Frank A. Wolak We analyze how market design influences bidding in multiunit procurement auctions where suppliers have asymmetric information about production costs. Our analysis is particularly relevant to wholesale electricity markets, because it accounts for the risk that a supplier is pivotal; market demand is larger than the total production capacity of its competitors. With constant marginal costs, expected welfare improves if the auctioneer restricts offers to be flat. We identify circumstances where the competitiveness of market outcomes improves with increased market transparency. We also find that, for buyers, uniform pricing is preferable to discriminatory pricing when producers’ private signals are affiliated. 1. Introduction Multiunit auctions are used to trade commodities, securities, emission permits, and other divisible goods. This article focuses on electricity markets, where producers submit offers before the level of demand and amount of available production capacity are fully known. Due to demand shocks, unexpected outages, transmission-constraints, and intermittent output from renewable energy sources, it often arises that an electricity producer is pivotal, that is, that realized demand is larger than the realized total production capacity of its competitors. A producer that is certain to be pivotal possess a substantial ability to exercise market power because it can withhold output ∗ Research Institute of Industrial Economics (IFN), Associate Researcher of the Energy Policy Research Group (EPRG), University of Cambridge; [email protected]. ∗∗ Program on Energy and Sustainable Development (PESD) and Stanford University; [email protected]. -

Escalation Revisited: Investigating the Influence of Personality and Organizational Support on Escalation of Commitment
Escalation Revisited: Investigating the Influence of Personality and Organizational Support on Escalation of Commitment by Julia Walsh Howell A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Doctor of Philosophy Auburn, Alabama August 2, 2014 Keywords: Escalation of commitment, personality, organizational support, sunk costs Copyright 2014 by Julia Walsh Howell Approved by Daniel Svyantek, Chair, Professor and Chair, Department of Psychology Ana Franco-Watkins, Associate Professor, Department of Psychology Alejandro Lazarte, Associate Professor, Department of Psychology Alan Walker, Associate Professor, Department of Management Abstract Escalation of commitment research has been narrow in its scope of influencing factors. A goal of this study was to remedy this gap by including factors at the individual, organizational, and decision context level that affect escalation. Furthermore, to my knowledge there is no other escalation research that has included both an economic and a human resources (HR) decision scenario. A significant contribution of this study was the results showing these two types of scenarios have different, and sometimes opposing, outcomes. In the economic context, sunk costs were positively related to escalation, but the relationship was inversed in the HR context. Additionally, facets of neuroticism and openness to experience were related to escalation in the economic context, but no such relationships were present in the HR context. Openness to experience moderated the relationship between organizational support and escalation. The results in the HR context have practical implications regarding how managers select, train, promote, and terminate employees. Furthermore, the differential outcomes in the economic and HR contexts provide a first step in expanding the theoretical implications of varying contexts and their influence on escalation. -
Survey of the Computational Complexity of Finding a Nash Equilibrium
Survey of the Computational Complexity of Finding a Nash Equilibrium Valerie Ishida 22 April 2009 1 Abstract This survey reviews the complexity classes of interest for describing the problem of finding a Nash Equilibrium, the reductions that led to the conclusion that finding a Nash Equilibrium of a game in the normal form is PPAD-complete, and the reduction from a succinct game with a nice expected utility function to finding a Nash Equilibrium in a normal form game with two players. 2 Introduction 2.1 Motivation For many years it was unknown whether a Nash Equilibrium of a normal form game could be found in polynomial time. The motivation for being able to due so is to find game solutions that people are satisfied with. Consider an entertaining game that some friends are playing. If there is a set of strategies that constitutes and equilibrium each person will probably be satisfied. Likewise if financial games such as auctions could be solved in polynomial time in a way that all of the participates were satisfied that they could not do any better given the situation, then that would be great. There has been much progress made in the last fifty years toward finding the complexity of this problem. It turns out to be a hard problem unless PPAD = FP. This survey reviews the complexity classes of interest for describing the prob- lem of finding a Nash Equilibrium, the reductions that led to the conclusion that finding a Nash Equilibrium of a game in the normal form is PPAD-complete, and the reduction from a succinct game with a nice expected utility function to finding a Nash Equilibrium in a normal form game with two players. -
