Facoltà di Economia

Dear all,

I have uploaded a pdf file (here) with the marks you have obtained at the exam plus the extra points you earned for participating in the experiments. Let me know if everything is correct.

If you see a star/asterisk near your mark, it means that the mark is conditional on whether you fill out the preliminary survey I have circulated some time ago (here). So, please, do this by this Saturday, so that I can proceed to register the marks on Delphi.

Best,

LC

Dear all,

this is to inform you that I have uploaded the solutions to the Practice we solved on March 26 and a Mock Exam (here) intended to give you an idea of the kind of questions and exercises I might propose you with, and the general structure of the exam.

I also remind you that the material in the slides' appendices is NOT mandatory, but just intended to assist you in your studies, and that auctions are excluded from the topics that can be asked you in this session.

See you tomorrow,

LC

This is intended only for students who will not be able to join the experimental session of today.

Dear students,

I am considering organizing a short online experiment for those that are unable to attend the session of today, which unfortunately is lab-only (unfortunately that software does not allow otherwise).

Interested students, please send me an email and I'll see how and when to organize it.

LC

Dear all,

apologies for this second email, but here is some important information about the experimental session of wednesday 27 held by Prof. Papa (and me) in S2.

In short: rejoyce greedy selfish payoff maximizers! This time, you will be paid monetarily based on the decisions you make in the experiment. All you need is a PayPal account (amount transferred max in 1 week).

To do that, before or after the experiment, you will have to:
1) show your Identity card number;
2) provide the email associated with the PayPal account;
3) sign a document authorizing the use of your data.

For this reason, if you can*, please come 5 minutes before 4pm (at least to complete these steps).

Note also that you might be subvidided into two shifts (16-17 and 17-18) based on how many of you show up (due to lab max capacity) and also on individual time constraints (e.g., you cannot leave after 18 for some prior commitment). This will be discussed beforehand on wednesday, so no worries.

Thank you.

LC

*How likely it is in your opinion that the lecture prior to mine ends at 16 or before? Can some of you send me an email to share your thoughts/beliefs on the matter? Thank you

Dear all,

this is to give you some indications on the upcoming experimental sessions (25/3 and 27/3) and the payoff structure for your participation in the activies, so read it carefully.

First of all, I kindly ask you to fill out this preparatory survey before the experiment of monday 25:

https://forms.gle/tDe1e79HbrBoj9oS6

The survey lasts around 15min and asks you about your personal characteristics and preferences, and also your matriculation number, which I will need to track attendance.

Second, there are two experiments scheduled, one on monday 25 in S4 and one on wednesday 27 in S2, at lecture time.

The experiment of monday 25 is open also to students attending on remote. I simply ask them to log on Teams around 4pm, as they would normally do for the lectures. Students attending in presence will join me in S4 at 4/4.15pm.

The payoff structure is as follows:

• survey completion + experiment of monday 25: +1 point
• survey completion + experiment of wednesday 27: +1point

Thank you. If you have any questions about the survey or the sessions, just let me know.

Have a nice weekend,

LC

TL;DR: today no frontal lecture, but we practice on some exercises and questions

Dear all,

apparently it is now spring and we are also nearing the end of the course. I have realized that I have covered much of what I wanted to teach you, and thus I believe that today we can slow down a little and simply revisit together some exercises and topics.

So here is the proposal for today: I have uploaded a pdf ("Practice", available here) with some questions and exercises that we will solve together "live". I would like you to solve each exercise on your own, with guidance on my part or on the part of your colleagues; we could consider also the idea of having volunteers solving them at the blackboard.

Sounds good?

I also remind you that on March 25 and 27 there will be experimental sessions in S2/S4, and that on the 26 I might schedule another practice session and/or comment on the results on the experiment of the 25. In simple words, I will not add any further topics for the exam, and you can use the time left to prepare for it.

Best,

LC

Dear all,

I have uploaded the slides for the next two lectures (https://economia.uniroma2.it/corso/asset/YTo0OntzOjI6ImlkIjtzOjQ6IjIyNDciO3M6MzoiaWRhIjtzOjU6IjcxODQxIjtzOjI6ImVtIjtiOjE7czoxOiJjIjtzOjU6IjhjYzVhIjt9).

The slides for the lecture of wednesday will be provided soon.

Note also that I have uploaded the exercises on social preferences and bayesian games (the topic of this week).

See you later,

LC

I know you were waiting for it, so here it is: the exercise handout volume III!

Available in teaching material section and at the links below.

Enjoy,

LC

PS: for any issues do not hesitate to send me an email or tell me in class. By the way, thanks again for your numerous participation in the experimental activity!

Dear all,

as anticipated in class, there are currently two experimental sessions scheduled:

1. Thursday 7/3 at 9.30am in S2, i.e. the computer room at the second floor of building A (or in any case the teaching building, I still haven't learned which letter denotes which one); this is what in the lecture section of the course page is labeled "pratice" (or "Esercitazione" for italians).

2. Wednesday 27/3 at 4pm (last lecture), in lab S2 again.

The participation to each will be rewarded with +1 point on the exam.

If you cannot attend one or both (and this is relevant for students that cannot attend in person but do so on remote), fear not: I am scheduling an activity that can be joined also on remote. Details will follow; all I can say for now is that it will likely take place on the 26/3 (my penultimate lecture), but I have still to finalize the organization with the administration.

That is all. See you tomorrow and possibly on Thursday.

LC

Dear all,

I have just uploaded the slides for this week in the Teaching Material section:

Dear all,

the second part of your favorite exercise handout has just been published (in the teaching material session; link below). If you find any typos or mistakes, or if you have doubts, please let me know via email or in class. I will upload the slides for the next week by monday morning at most.

Have a nice weekend,

Yours truly,

Handout P2: https://economia.uniroma2.it/corso/asset/YTo0OntzOjI6ImlkIjtzOjQ6IjIyNDciO3M6MzoiaWRhIjtzOjU6IjcxMzcxIjtzOjI6ImVtIjtiOjE7czoxOiJjIjtzOjU6ImQ0YTI2Ijt9

Handout P2 (solved):

Dear all,

I have added a short topic to the slides pack for this week, i.e. a variant of the Grim Trigger strategy, which I will present to you today. You find the new version of the slides in the teaching material (https://economia.uniroma2.it/corso/asset/YTo0OntzOjI6ImlkIjtzOjQ6IjIyNDciO3M6MzoiaWRhIjtzOjU6IjcxMjA1IjtzOjI6ImVtIjtiOjE7czoxOiJjIjtzOjU6IjA4M2QwIjt9).

I am also going to solve with you 1-2 exercises for each of the topics we have covered this week, so that you can see the full process and confidently solve this type of exercises on your own in preparation for the exam.

Finally, mind that we have decided to start each lecture by default at 4.15pm. Do not worry, I will still finish my lecture at 5.30pm; to do that, I simply shift the final part of each lecture, devoted to solving the exercises, to the last lecture of the week (as I will do today).

See you later,

LC

Dear all,

I have uploaded the slides for this week on the course webpage, in the Teaching Material session

https://economia.uniroma2.it/corso/asset/YTo0OntzOjI6ImlkIjtzOjQ6IjIyNDciO3M6MzoiaWRhIjtzOjU6IjcxMjA1IjtzOjI6ImVtIjtiOjE7czoxOiJjIjtzOjU6IjA4M2QwIjt9

See you this afternoon,

LC

Dear students,

as anticipated, I have just uploaded the first part of the exercises handout on the topics of the course (GT23-24 Exercises Handout - Part I). I have also attached the version with the solutions.

I hope this offers you an opportunity to practice on what we have studied so far as well as to spend a nice alternative weekend (it might also give you an excuse to decline an invitation or date request from a non-significant other).

By the way, the handout also includes some exercises on Bertrand's model, which we have not covered yet. But if you want to try on your own, go ahead: I am confident you can do it!

See you on monday,

LC

Dear students,
