Introduction to Computational Social Choice
1 Introduction to Computational Social Choice Felix Brandta, Vincent Conitzerb, Ulle Endrissc, J´er^omeLangd, and Ariel D. Procacciae 1.1 Computational Social Choice at a Glance Social choice theory is the field of scientific inquiry that studies the aggregation of individual preferences towards a collective choice. For example, social choice theorists|who hail from a range of different disciplines, including mathematics, economics, and political science|are interested in the design and theoretical evalu- ation of voting rules. Questions of social choice have stimulated intellectual thought for centuries. Over time the topic has fascinated many a great mind, from the Mar- quis de Condorcet and Pierre-Simon de Laplace, through Charles Dodgson (better known as Lewis Carroll, the author of Alice in Wonderland), to Nobel Laureates such as Kenneth Arrow, Amartya Sen, and Lloyd Shapley. Computational social choice (COMSOC), by comparison, is a very young field that formed only in the early 2000s. There were, however, a few precursors. For instance, David Gale and Lloyd Shapley's algorithm for finding stable matchings between two groups of people with preferences over each other, dating back to 1962, truly had a computational flavor. And in the late 1980s, a series of papers by John Bartholdi, Craig Tovey, and Michael Trick showed that, on the one hand, computational complexity, as studied in theoretical computer science, can serve as a barrier against strategic manipulation in elections, but on the other hand, it can also prevent the efficient use of some voting rules altogether. Around the same time, a research group around Bernard Monjardet and Olivier Hudry also started to study the computational complexity of preference aggregation procedures. -

Stable Matching: Theory, Evidence, and Practical Design
THE PRIZE IN ECONOMIC SCIENCES 2012 INFORMATION FOR THE PUBLIC Stable matching: Theory, evidence, and practical design This year’s Prize to Lloyd Shapley and Alvin Roth extends from abstract theory developed in the 1960s, over empirical work in the 1980s, to ongoing efforts to fnd practical solutions to real-world prob- lems. Examples include the assignment of new doctors to hospitals, students to schools, and human organs for transplant to recipients. Lloyd Shapley made the early theoretical contributions, which were unexpectedly adopted two decades later when Alvin Roth investigated the market for U.S. doctors. His fndings generated further analytical developments, as well as practical design of market institutions. Traditional economic analysis studies markets where prices adjust so that supply equals demand. Both theory and practice show that markets function well in many cases. But in some situations, the standard market mechanism encounters problems, and there are cases where prices cannot be used at all to allocate resources. For example, many schools and universities are prevented from charging tuition fees and, in the case of human organs for transplants, monetary payments are ruled out on ethical grounds. Yet, in these – and many other – cases, an allocation has to be made. How do such processes actually work, and when is the outcome efcient? Matching theory The Gale-Shapley algorithm Analysis of allocation mechanisms relies on a rather abstract idea. If rational people – who know their best interests and behave accordingly – simply engage in unrestricted mutual trade, then the outcome should be efcient. If it is not, some individuals would devise new trades that made them better of. -

Received: February 10, 2020 Accepted: February 28, 2020 Online Published: March 4, 2020 doi:10.5539/mas.v14n4p1 URL: https://doi.org/10.5539/mas.v14n4p1 Abstract Game theory approach is used in this study that involves two types of games which are noncooperative and cooperative. Noncooperative game is used to get the equilibrium solutions from each payoff matrix. From the solutions, the values then be used as characteristic functions of Shapley value solution concept in cooperative game. In this paper, the sectors are divided into three groups where each sector will have three different stocks for the game. This study used the companies that listed in Bursa Malaysia and the prices of each stock listed in this research obtained from Datastream. The rate of return of stocks are considered as an input to get the payoff from each stock and its coalition sectors. The value of game for each sector is obtained using Shapley value solution concepts formula to find the optimal increase of the returns. The Shapley optimal portfolio, naive diversification portfolio and market portfolio performances have been calculated by using Sharpe ratio. -

The Neumann Lecture (By Prof. Glenn C. Loury, Brown University)*
The Neumann Lecture (by Prof. Glenn C. Loury, Brown University)* My lecture tonight will be about race and racial inequality in the United States. I will try to give you some idea of what I think I'm contributing to the study of this subject in my work. In order to do that I need to give some background, to create something of an intellectual context into which my work will fit. Indeed, I will begin by describing some aspects of the work of last year's von Neumann laureate – the renowned economist Gary S. Becker of the University of Chicago, who has addressed himself over the past few decades to related questions. Then I will try to convince you that my ideas extend and amplify and deepen Becker’s work. But I don't think it will be enough just to talk about my ideas. I think one also has to talk about what might be done about this situation – about the politics and the morality, the social morality, the social ethics that are raised by this question of social division, of “race,” within a society. I am aware that here in Hungary you know something about this question. I spent some time just today with the Minister of Equal Opportunities and her staff discussing the Roma question, and nationalities questions, and inequality questions that pertain to Hungary. I don't know very much about those things and I won't be speaking about those things directly here. I will be talking about the United States, which is the case that I know best. -

Cooperation in a Peer Production Economy Experimental Evidence from Wikipedia*
Cooperation in a Peer Production Economy Experimental Evidence from Wikipedia* Yann Algan† Yochai Benkler‡ Mayo Fuster Morell§ Jérôme Hergueux¶ July 2013 Abstract The impressive success of peer production – a large-scale collaborative model of production primarily based on voluntary contributions – is difficult to explain through the assumptions of standard economic theory. The aim of this paper is to study the prosocial foundations of cooperation in this new peer production economy. We provide the first field test of existing economic theories of prosocial motives for contributing to real-world public goods. We use an online experiment coupled with observational data to elicit social preferences within a diverse sample of 850 Wikipedia contributors, and seek to use to those measures to predict subjects’ field contributions to the Wikipedia project. We find that subjects’ field contributions to Wikipedia are strongly related to their level of reciprocity in a conditional Public Goods game and in a Trust game and to their revealed preference for social image within the Wikipedia community, but not to their level of altruism either in a standard or in a directed Dictator game. Our results have important theoretical and practical implications, as we show that reciprocity and social image are both strong motives for sustaining cooperation in peer production environments, while altruism is not.

An Experimental Investigation of Electoral Delegation and the Provision of Public Goods
An Experimental Investigation of Electoral Delegation and the Provision of Public Goods John R. Hamman Florida State University Roberto A. Weber University of Zurich Jonathan Woon University of Pittsburgh How effectively do democratic institutions provide public goods? Despite the incentives an elected leader has to free ride or impose majority tyranny, our experiment demonstrates that electoral delegation results in full provision of the public good. Analysis of the experimental data suggests that the result is primarily due to electoral selection: groups elect prosocial leaders and replace those who do not implement full contribution outcomes. However, we also observe outcomes in which a minimum winning coalition exploits the contributions of the remaining players. A second experiment demonstrates that when electoral delegation must be endogenously implemented, individuals voluntarily cede authority to an elected agent only when preplay communication is permitted. Our combined results demonstrate that democratic delegation helps groups overcome the free-rider problem and generally leads to outcomes that are often both efficient and equitable. ocial scientists have long recognized individuals’ to Hobbes’ ideal vision of an absolute sovereign, decision strong incentives to “free ride” on the contribu- makers in modern democratic governments wield their S tionsofotherswhenpublicgoodsareprovided power temporarily, subject to popular approval, and reg- through decentralized, voluntary institutions (Dawes ular elections give citizens the opportunity to select new 1980; Hardin 1968; Lindahl 1919; Olson 1965; Samuelson leaders. 1954).

Economic Engineering of Human Cooperation and Competition
The University of Cologne New York Office, the German Research Foundation (DFG) and the German Center for Research and Innovation (GCRI) cordially invite you to a Leibniz lecture on: Economic Engineering of Human Cooperation and Competition Tuesday, October 23, 2018 6:30 p.m. - 8:00 p.m. Prof. Dr. Axel Ockenfels Gottfried Wilhelm Leibniz Award 2005 Professor of Economics University of Cologne Location: German House, 871 United Nations Plaza, New York, NY 10017 Please RSVP by October 21. Registration is required to attend the lecture. What do climate change, shortage of organ donors, and traffic congestion have in common? They can all be addressed with behavioral economics. Join us for a lecture by Leibniz Prize recipient Professor Axel Ockenfels. Many economic and societal challenges can only be addressed with a change in human behavior. Market design can offer solutions because market rules affect our behavior in predictable ways. Traffic jams, for example, cost time, money and impact our health, while recent advances in technology would allow for the design of new markets for road use that promote cooperation and prevent congestion. Climate change is fundamentally a problem of insufficient cooperation that can be addressed if recognized as such and acted on accordingly in international climate negotiations. In his lecture, Professor Ockenfels will show how market rules can be engineered to promote cooperation and trust even in large communities and to encourage competition in small markets. Professor Ockenfels’ focus will be on human behavior in markets, which responds to market rules, but rarely in a fully rational way. He will show how market design can take on real-world challenges.
