What is the course about? Social Choice – the name captures all … and nothing. It is about choice in society. How Societies should choose. How Societies could choose. How societies can choose. How Societies do choose. It is an enormous topic and you are not expected to memorise all the detail in all its complexity. We want you to get an overview. Do not read and memorise … think and generalise.

The organisation of the course We have some lectures. We have some debates. We have some experiments. We have some discussions. There is a problem in that there are lots of students on the course. This creates organisational difficulties. We are happy if the uncommitted students drop out. We only want committed students who will take an active role and interact with us and the other students.

The website Please look at this frequently: choice/

Lectures All the lectures will be available via the site. We recommend that you look at them both before and after the lectures… … so that you come prepared. You are not expected to memorise the lectures but instead understand the theme of the lectures and be able to take away general conclusions. There will be some reading recommended but you are not expected to memorise the content.

The other activities: experiments, debates, discussions, exercise classes With such a large number of students we are not quite sure yet how we are going to organise these other activities. But we expect students to take an active role. We may have to split up the group into smaller groups in some way. We may run some experiments in the CESARE laboratory which is at Viale Pola. We will be asking for volunteers to take part in the debates.

Assessment We know that this is not important to you, but there are two methods of assessment: A conventional examination. Assessment by Group Project in which a self-appointed group of students write a project on a self-chosen topic approved by us. Some titles from last year: Berlusconi and Italian Politics: Why Italians Chose a Business Man Named Silvio Berlusconi? Ill and Poor: Better it to be in the UK or in France? Is it better to live in a dictatorship or in a democracy? The Value of the Vote Mind the Gap! How come Israel had a woman prime minister and Italy not (yet!)? Social Order: How is social order sustained in human societies? Voting Systems and Fairness: Two railway tracks: Parallel as in reality or converging as if seen in perspective? In Sickness and in Health – better to be British or French? If we decide to establish a new nation, which legal system would we choose?
