Introductory description

This module develops mathematical models to study collective decision making and analyse the rational behaviour of voters, politicians, and government officials from the perspective of economic theory. Students are introduced to the theory of social choice, studying various ways of aggregating individual preferences into a coherent collective decision, and the fundamental trade-offs any democratic voting mechanism faces. Next, students study game-theoretic models of political competition in elections. The module moves on to look at how a group can aggregate information better (or worse) than each of its members and the problems of coordination and free-riding in competing groups of political agents. Overall, this module provides the formal basis for positive and normative analysis of many democratic institutions.

Module aims

In many economic and political environments, a group of individuals must make a decision that will affect all of its members. Examples abound, including voting in elections, juries, and corporate boards. How to aggregate individual preferences in an optimal way? How different decision-making procedures affect the collective outcomes? This module develops mathematical models to formulate and answer these questions in a precise way. It will provide students with an introduction to the theory of social choice, conventionally defined as the study of the decision-making behaviour of voters, politicians, and government officials from the perspective of economic theory. It can be considered as a bridge between economics and political science, an introduction into more advanced topics in political economy. As such the module has an important role in contributing to the achievement of the aims of the joint degrees in Philosophy, Politics and Economics (PPE) and Economics, Politics and International Studies (EPAIS). However, the module will also appeal to students taking degrees taught entirely within the Economics department, and others.

Outline syllabus

This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.

The module will typically cover some of the following topics: Voting as preference aggregation; the social choice approach. Voting rules: unanimity, simple majority. Problems of majority voting: cycling, Arrow’s impossibility theorem. Restrictions on preference profiles. The single crossing property. Gibbard-Satterthwaite Theorem, strategy-proofness. Voting with more than two alternatives: majoritarian methods, Condorcet extensions, and positional methods. The spatial model of elections. Majority rule core, global cycling, McKelvey’s chaos theorem. Game theoretic approaches; two party competition, median voter theorem. Agenda manipulation. Public choice in a representative democracy; voting over redistribution. Bargaining in legislatures. Public goods and collective action; paradox of voting. Voting with incomplete information; Condorcet Jury theorem.

Feedback on assessment

The Department of Economics is committed to providing high quality and timely feedback to students on their assessed work, to enable them to review and continuously improve their work. We are dedicated to ensuring feedback is returned to students within 20 University working days of their assessment deadline. Feedback for assignments is returned either on a standardised assessment feedback cover sheet which gives information both by tick boxes and by free comments or via free text comments on tabula, together with the annotated assignment. For tests and problem sets, students receive solutions as an important form of feedback and their marked assignment, with a breakdown of marks and comments by question and sub-question. Students are informed how to access their feedback, either by collecting from the Undergraduate Office or via tabula. Module leaders often provide generic feedback for the cohort outlining what was done well, less well, and what was expected on the assignment and any other common themes. This feedback also includes a cumulative distribution function with summary statistics so students can review their performance in relation to the cohort. This feedback is in addition to the individual-specific feedback on assessment performance.
