A Class of N-Player Colonel Blotto Games with Multidimensional Private Information
University of Zurich Department of Economics Working Paper Series ISSN 1664-7041 (print) ISSN 1664-705X (online) Working Paper No. 336 A Class of N-Player Colonel Blotto Games with Multidimensional Private Information Christian Ewerhart and Dan Kovenock Revised version, February 2021 A Class of N-Player Colonel Blotto Games With Multidimensional Private Information Christian Ewerhart Dan Kovenocky Department of Economics Economic Science Institute University of Zurich Chapman University Revised version: February 1, 2021 Abstract. In this paper, we study N-player Colonel Blotto games with incomplete information about battlefield valuations. Such games arise in job markets, research and development, electoral competition, security analysis, and conflict resolution. For M N + 1 battlefields, we identify a Bayes-Nash equilibrium in which the resource ≥ allocation to a given battlefield is strictly monotone in the valuation of that battlefield. We also explore extensions such as heterogeneous budgets, the case M N, full-support ≤ type distributions, and network games. Keywords.

The player that deploys the largest amount of the resource to a given battlefield scores a win and enjoys a gain in utility equivalent to her valuation of that battlefield. Thus, a player’s utility corresponds to the sum of the valuations of all battlefields won by the player. -

They may discuss the answers in the groups and report back to you as the instructor. Write down the answers to these questions and compile a working definition. Try to lead the youth so that they do not name a specific game but keep in mind various games that they know and use specific attributes of them to make generalizations. · What is a game? · Are there different types of games? · What make something a game and something else not a game? · What is a board game? · How is it different from other types of games? · Do you always know what your opponent (other player) is doing during the game, can they be sneaky? · Do all of games have the same qualities as the games definition that we just made? Why or why not? Game history: The earliest known board games are thought of to be either ‘Go’ from China (which we are about to learn a variation of), or Senet and Mehen from Egypt (a country in Africa) or Mancala. -
Understanding Emotions in Electronic Auctions: Insights from Neurophysiology
Understanding Emotions in Electronic Auctions: Insights from Neurophysiology Marc T. P. Adam and Jan Krämer Abstract The design of electronic auction platforms is an important field of electronic commerce research. It requires not only a profound understanding of the role of human cognition in human bidding behavior but also of the role of human affect. In this chapter, we focus specifically on the emotional aspects of human bidding behavior and the results of empirical studies that have employed neurophysiological measurements in this regard. By synthesizing the results of these studies, we are able to provide a coherent picture of the role of affective processes in human bidding behavior along four distinct theoretical pathways. 1 Introduction Electronic auctions (i.e., electronic auction marketplaces) are information systems that facilitate and structure the exchange of products and services between several potential buyers and sellers. In practice, electronic auctions have been employed for a wide range of goods and services, such as commodities (e.g., Internet consumer auction markets, such as eBay.com), perishable goods (e.g., Dutch flower markets, such as by Royal FloraHolland), consumer services (e.g., procurement auction markets, such as myhammer.com), or property rights (e.g., financial double auction markets such as NASDAQ). In this vein, a large share of our private and commercial economic activity is being organized through electronic auctions today (Adam et al. 2017;Kuetal.2005). Previous research in information systems, economics, and psychology has shown that the design of electronic auctions has a tremendous impact on the auction M. T. P.

The course starts by examining the motivations for and challenges of forming political states and institutions, and how the structure and workings of political institutions a ect economic outcomes and societal welfare. Topics include: the origins of states, anarchy and the social contract, liberalism, wars and arms races, constitutional design, federalism, models of strategic voting behavior, asymme- tries of information and voting behavior, agenda formation and control, logrolling, lobbying, vote-buying and political in uence, nomination processes, and the politics of federations of states. Prerequisite: Economics 220. Requirements: You will be continuing the work on the projects that you began in Economics 220. This will involve re ning a model and producing some results if the problem you proposed in 220 was theoretical in nature, and if the work is empirical, then you should begin or continue your analysis of data. There will be several di erent due dates of updates on the project. The projects will be judged based on the progress made past what was completed in 220. In the latter part of the course, there will also be student presentations and discussions of some of the papers. A note on the readings and class discussions: Reading the papers before class is critical to the course, as much of the emphasis of the course will not only be on \what" the papers tell us, but also on \why" these are interesting issues and \how" the research was conducted. -
Generalizations on the Colonel Blotto Game
Generalizations on the Colonel Blotto Game Dan Kovenock∗and Brian Robersony Abstract In this paper we characterize the equilibrium in a relaxed version of the Colonel Blotto game in which battlefield valuations maybe heterogeneous across battlefields and asymmetric across players and the, possibly asymmetric, budget constraints hold only on average, and then show how this characterization partially extends to the full Colonel Blotto game, in which the budget constraints must be satisfied with probability one. For the non-constant-sum generalization of the Colonel Blotto game examined, we find that there exist non-pathological parameter configurations with multiple, payoff inequivalent, equilibria. ∗Dan Kovenock, Economic Science Institute, Argyros School of Business and Economics, Chapman Uni- versity, One University Drive, Orange, CA 92866 USA t:714-628-7226 E-mail: [email protected] yBrian Roberson, Purdue University, Department of Economics, Krannert School of Management, 403 W. State Street, West Lafayette, IN 47907 USA t: 765-494-4531 E-mail: [email protected] (Correspondent) 1 1 Introduction The Colonel Blotto game is a two-player resource allocation game in which each player is endowed with a level of resources to allocate across a set of battlefields, within each battlefield the player that allocates the higher level of resources wins the battlefield, and each player's payoff is the sum of the valuations of the battlefields won. This simple game, that originates with Borel (1921), illustrates the fundamental strategic considerations that arise in multi- dimensional resource allocation competition such as: political campaign resource allocation, research and development competition where innovation involves obtaining a collection of interrelated patents, attack and defense of a collection of targets, etc. -
Faster and Simpler Algorithm for Optimal Strategies of Blotto Game
Faster and Simpler Algorithm for Optimal Strategies of Blotto Game Soheil Behnezhad∗, Sina Dehghani∗, Mahsa Derakhshan∗, MohammadTaghi HajiAghayi∗, Saeed Seddighin∗ Department of Computer Science, University of Maryland fsoheil, dehghani, mahsaa, hajiagha, [email protected] Abstract In the Colonel Blotto game, which was initially introduced by Borel in 1921, two colonels simultaneously distribute their troops across different battlefields. The winner of each battlefield is determined independently by a winner-take-all rule. The ultimate payoff of each colonel is the number of battlefields he wins. The Colonel Blotto game is commonly used for analyzing a wide range of applications from the U.S presidential election, to innovative technology competitions, to advertisement, to sports, and to politics. There has been persistent efforts for finding the optimal strategies for the Colonel Blotto game. After almost a century Ahmadinejad, Dehghani, Hajiaghayi, Lucier, Mahini, and Seddighin [2] provided an algorithm for finding the optimal strategies in polynomial time. Ahmadinejad et al. [2] first model the problem by a Linear Program (LP) with both an expo- nential number of variables and an exponential number of constraints which makes the problem intractable. Then they project their solution to another space to obtain another exponential-size LP, for which they can use Ellipsoid method. However, despite the theoretical importance of their algorithm, it is highly impractical. In general, even Simplex method (despite its exponen- tial running time in practice) performs better than Ellipsoid method in practice. In this paper, we provide the first polynomial-size LP formulation of the optimal strategies for the Colonel Blotto game. We use linear extension techniques. -
