This talk was given at a local TEDx event, produced independently of the TED Conferences. Para más charlas de TEDxCordoba: http://www.tedxcordoba.com.ar + Martín Tetaz. Economista y autor de “Psychonomics: la economía está en tu mente”. La Plata, Buenos Aires. + In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
