This module develops mathematical models of collective decision making that form the standard corpus of modern political economy frameworks and applies them to study the rational behaviour of voters, politicians, and government officials.
The module first introduces the students to the theory of social choice, analysing various ways of aggregating individual preferences into a coherent collective decision, and demonstrates the fundamental trade-offs any democratic mechanism faces. Next, game-theoretic models of political competition in elections are covered in details. The module then moves on to analyse 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 political institutions.
Principal Learning Outcomes
Subject Knowledge and Understanding :...demonstrate knowledge and understanding of: Political economy: the decision-making behaviour of voters, politicians and government officials from the perspective of economic theory. The teaching and learning methods that enable students to achieve this and all other learning outcome are: Lectures, seminars, problem sets, and background reading. The summative assessment methods that measure the achievement of this and other learning outcomes are: Midterm and Final Examination.
Cognitive skills:...demonstrate capacity of: Abstraction and Problem solving. Applying critical analysis to the topics of the module, formulating concepts and hypotheses, and showing how they are tested in relevant literature.
Cognitive skills:...demonstrate capacity of: Critical, creative and strategic thinking.
Key Skills:...demonstrate proficiency in study and research skills such as: reviewing the relevant literature and evidence.
Key Skills:...demonstrate proficiency in study and research skills such as: communicating their knowledge and understanding to others, verbally and in writing.

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.
