Course Overview
The course aims to provide students with a grounding in the main areas of behavioral economics,
by focusing on behavioral implications of theoretical models and on experimental evidence in
economics. These main areas include bounded rationality, decision-making under risk and uncertainty, other regarding preferences, intertemporal decision-making, behavioral game theory,
emotions and libertarian paternalism. For each area, the focus will be on three points: (i) review of standard economic models and evidence that indicates that such models do not capture
some important behavioral aspects or anomalies; (ii) study of the behavioral models that have
been developed to capture these aspects; (iii) application of these models to different economic
fields, especially with respect to more recent contributions. In particular, lectures will deal with
the first two points, while the third one will be developed by means of assignments over the
semester.
Preparatory and General Readings
By and large, the course will be based on academic papers (which are available online) and
lecture notes (slides). However, besides the assigned reading list, there are some books that you
may find useful, if you are interested in getting a deeper knowledge about behavioral and experimental economics. The first is ’Advances in Behavioral Economics’ (2004) by Colin Camerer,
George Loewenstein and Matthew Rabin. The second is ’An Introduction to Behavioral Economics’ (2012) by Nick Wilkinson and Klaes. The third is ’Behavioral Game Theory’ (2003) by
Colin Camerer. Finally there is ’Handbook of Experimental Economics’ (1995) by John Kagel
and Alvin Roth.
Here you can also find the suggestion of some interesting readings: ’Gut Feelings’ (2008) by
Gerd Gigerenzer, ’Nudge’ (2009) by Richard Thaler and Cass Sustein, ’Predictably Irrational’
(2009) by Dan Ariely, ’The Upside of Irrationality’ (2010) by Dan Ariely, ’The Honest Truth
about Dishonesty’ (2013) by Dan Ariely, ’Thinking, Fast and Slow’ (2011) by Daniel Kahneman,
’The Power of Habit’ (2012) by Charles Duhigg, and ‘Foundations of Behavioral Economic
Analysis’ (2015) by Sanjit Dhami.

Course Requirements and Assessment Method
Students will be expected to be familiar with Mathematics, Statistics, Microeconomics, and
Game Theory.
Assessment for Master Students
There will be a final written exam. The final grade will depend also on a classroom presentation
on one of the covered topics.
Assessment for PhD Students
There will be a final written exam. The final grade will depend also on homeworks: indeed,
students are expected to hand in an assignment (more details will be provided during the
course), and a research proposal. Such a proposal should include a brief and clear review of the
existing (and also recent) literature, a description of the novelty of the proposed work, research
questions, and research methodology. Proposals can be organized in groups.

Papers marked with # are compulsory readings: they are the required readings for PhD
and Class-Only master students. You are expected to read these papers. The rest of the
list includes recommended readings, which will not explicitly required for exam preparation.
The shorter reading list for Take-Home master students will be published in a
separate document (which will be available on Comunità Online as well). Anyhow, it will be a
