Consider a setting in which individual strict preferences need to be aggregated into a social strict preference relation. For two alternatives and an odd number of agents, it follows from May's Theorem that the majority aggregation rule is the only one satisfying anonymity, neutrality, and strategy-proofness (SP). For more than two alternatives, anonymity and neutrality are incompatible in many instances and we explore this tradeoff for strategy-proof rules. The notion of SP that we employ is Kemeny-SP (K- SP), which is based on the Kemeny distance between social orderings and strengthens previously used concepts in an intuitive manner. Dropping anonymity and keeping neutrality, we identify and analyze the first known nontrivial family of K-SP rules, namely semi-dictator rules. For two agents, semi-dictator rules are characterized by local unanimity, neutrality, and K-SP. For an arbitrary number of agents, we generalize semi-dictator rules to allow for committees and show that they retain their desirable properties. Dropping neutrality and keeping anonymity, we establish possibility results for three alternatives. We provide a computer-aided solution to the existence of a locally unanimous, anonymous, and K-SP rule for two agents and four alternatives. Finally, we show that there is no K-SP and anonymous rule which always chooses one of the agents' preferences.

Computational social choice is concerned with the design and analysis of methods for collective decision making. It is a research area that is located at the interface of computer science and economics. The central question studied in computational social choice is that of how best to aggregate the individual points of view of several agents, so as to arrive at a reasonable compromise. Examples include tallying the votes cast in an election, aggregating the professional opinions of several experts, and finding a fair manner of dividing a set of resources amongst the members of a group -- Back cover.

The rapidly growing field of computational social choice, at the intersection of computer science and economics, deals with the computational aspects of collective decision making. This handbook, written by thirty-six prominent members of the computational social choice community, covers the field comprehensively. Chapters devoted to each of the field's major themes offer detailed introductions. Topics include voting theory (such as the computational complexity of winner determination and manipulation in elections), fair allocation (such as algorithms for dividing divisible and indivisible goods), coalition formation (such as matching and hedonic games), and many more. Graduate students, researchers, and professionals in computer science, economics, mathematics, political science, and philosophy will benefit from this accessible and self-contained book.

Models in Microeconomic Theory covers basic models in current microeconomic theory. Part I (Chapters 1-7) presents models of an economic agent, discussing abstract models of preferences, choice, and decision making under uncertainty, before turning to models of the consumer, the producer, and monopoly. Part II (Chapters 8-14) introduces the concept of equilibrium, beginning, unconventionally, with the models of the jungle and an economy with indivisible goods, and continuing with models of an exchange economy, equilibrium with rational expectations, and an economy with asymmetric information. Part III (Chapters 15-16) provides an introduction to game theory, covering strategic and extensive games and the concepts of Nash equilibrium and subgame perfect equilibrium. Part IV (Chapters 17-20) gives a taste of the topics of mechanism design, matching, the axiomatic analysis of economic systems, and social choice. The book focuses on the concepts of model and equilibrium. It states models and results precisely, and provides proofs for all results. It uses only elementary mathematics (with almost no calculus), although many of the proofs involve sustained logical arguments. It includes about 150 exercises. With its formal but accessible style, this textbook is designed for undergraduate students of microeconomics at intermediate and advanced levels.

Daniel Solove presents a startling revelation of how digital dossiers are created, usually without the knowledge of the subject, & argues that we must rethink our understanding of what privacy is & what it means in the digital age before addressing the need to reform the laws that regulate it.

Making, amending, and interpreting constitutions is a political game that can yield widespread suffering or secure a nation's liberty and prosperity. Given these high stakes, Robert Cooter argues that constitutional theory should trouble itself less with literary analysis and arguments over founders' intentions and focus much more on the real-world consequences of various constitutional provisions and choices. Pooling the best available theories from economics and political science, particularly those developed from game theory, Cooter's economic analysis of constitutions fundamentally recasts a field of growing interest and dramatic international importance. By uncovering the constitutional incentives that influence citizens, politicians, administrators, and judges, Cooter exposes fault lines in alternative forms of democracy: unitary versus federal states, deep administration versus many elections, parliamentary versus presidential systems, unicameral versus bicameral legislatures, common versus civil law, and liberty versus equality rights. Cooter applies an efficiency test to these alternatives, asking how far they satisfy the preferences of citizens for laws and public goods. To answer Cooter contrasts two types of democracy, which he defines as competitive government. The center of the political spectrum defeats the extremes in "median democracy," whereas representatives of all the citizens bargain over laws and public goods in "bargain democracy." Bargaining can realize all the gains from political trades, or bargaining can collapse into an unstable contest of redistribution. States plagued by instability and contests over redistribution should move towards median democracy by increasing transaction costs and reducing the power of the extremes. Specifically, promoting median versus bargain democracy involves promoting winner-take-all elections versus proportional representation, two parties versus multiple parties, referenda versus representative democracy, and special governments versus comprehensive governments. This innovative theory will have ramifications felt across national and disciplinary borders, and will be debated by a large audience, including the growing pool of economists interested in how law and politics shape economic policy, political scientists using game theory or specializing in constitutional law, and academic lawyers. The approach will also garner attention from students of political science, law, and economics, as well as policy makers working in and with new democracies where constitutions are being written and refined.

Judgment aggregation is a mathematical theory of collective decision-making. It concerns the methods whereby individual opinions about logically interconnected issues of interest can, or cannot, be aggregated into one collective stance. Aggregation problems have traditionally been of interest for disciplines like economics and the political sciences, as well as philosophy, where judgment aggregation itself originates from, but have recently captured the attention of disciplines like computer science, artificial intelligence and multi-agent systems. Judgment aggregation has emerged in the last decade as a unifying paradigm for the formalization and understanding of aggregation problems. Still, no comprehensive presentation of the theory is available to date. This Synthesis Lecture aims at filling this gap presenting the key motivations, results, abstractions and techniques underpinning it.
