Barcelona Meeting, 16-18 October 2013

On this page you find practical information regarding the MC/WG Meeting of COST Action IC1205 on Computational Social Choice at the Institute for Economic Analysis (CSIC), Bellaterra (Barcelona) on 16-18 October 2013. The Institute for Economic Analysis is located at the campus of the Universitat Autònoma de Barcelona (UAB), which is a 30 minutes train ride from downtown Barcelona. Péter Biró and Jérôme Lang are the scientific organizers. The local organizer is Flip Klijn.

Registration and Program

The meeting starts on October 16, 15:00, ends on October 18, 14:00 and includes coffee breaks on all three days, lunch on Thursday and Friday, and dinner on Thursday. We invite all participants to also attend a seminar (October 16, 13:50-15:00) that precedes the meeting and which is given by Annick Laruelle at the Faculty of Economics and Business Studies (UAB). The Department of Economics and Economic History (UAB) kindly provides a light lunch right before the seminar.

The meeting is open for both members and non-members of the COST Action. There is no fee for attendance. The two lunches, all coffee breaks, and the dinner will be free of charge for all participants that register (member and non-members of the COST action) by sending an email to before September 30, 2013.

The program has been put together by Péter Biró, Jérôme Lang, and Ulle Endriss. There are two main themes: judgment aggregation (WG3) and matching (WG4). For the rump session, the idea is that anyone who's interested can give a 5-minute talk on the spot (please consider participating!; there will be a list for you to sign up in the meeting room). After lunch on Friday, there's the option to stick around for informal meetings.

Barcelona is both a very popular tourist destination and the venue of many conferences and meetings throughout the year. We have reserved 40 rooms at Hotel Catalonia Diagonal Centro (approximately 117 euros per night, including breakfast). This hotel is very conveniently located next to a station of the train (Provença) to the workshop venue  and within walking distance to popular sites in downtown Barcelona. To reserve a room in this hotel (first come, first served), you can contact Eliseo Palomar (, providing the following information:

Name, affiliation, country, email, day of arrival, day of departure, comments (e.g., dietary restrictions).

In the event that you would prefer to stay elsewhere in Barcelona, here is a small list of suggestions for accommodation. You would need to book these yourself. Please find the contact persons of the suggested hotels. Below you will find a map with the suggested locations:

Venue of Meeting and Travel

The meeting will take place at the Institute for Economic Analysis, Bellaterra.

  Information on how to travel from the airport to downtown Barcelona:

  • By Barcelona Express Shuttle Service (Aerobus): Aerobus A1 from terminal 1 (T1) and Aerobus A2 from terminal 2 (T2). You will find them outside each of the terminals. Tickets can be bought directly from the driver (approximately 6).
  • By taxi: It will cost you around 25-30. Not all taxis accept credit cards, so ask the driver first if necessary.

Information on how to travel from the airport to the workshop venue:

  • By taxi: It may be the fastest, but also the most expensive way to come to the workshop venue which is situated at the Universitat Autonoma de Barcelona Campus (UAB). You can reach UAB by taking the motorway C-58, direction Sabadell-Terrassa, exit "Universitat Autonoma" (see map). It will cost you around 50. Not all taxis accept credit cards, so ask the driver first if necessary.

Information on how to travel from downtown Barcelona to the workshop venue:

Tickets can be bought from the automatic vending machines inside the stations. Downtown Barcelona is in "zone 1" and the UAB campus is in "zone 2", so you will need to buy a single 2 zones ticket. However, you have also the option to buy a multi-person travel card valid for 10 journeys, called T10. The train journey takes approximately 30 minutes and there is a train every 10 minutes. More information on how to reach the workshop venue from downtown Barcelona is available here.

  • Get to the nearest Ferrocarrils de la Generalitat de Catalunya (FGC) Ferrocarrils station (Provença, Plaça Catalunya, Gracia). Line: Barcelona - Vallès.
  • Take any train signalled with "SabadellS2 (S2) or "Universitat Autònoma" (S55).
  • Get off the train at "Universitat Autònoma".
  • Use the following map to walk to the Institute (5 minutes).
