Еще про рациональность в экономике

Another research paper, “Paying Not to Go to the Gym,” published in the American Economic Review in 2006 and co-authored with Berkeley Economics Professor Stefano DellaVigna, shows that people with monthly gym memberships tend to use their membership far too infrequently to justify the monthly dues – paying per visit would be much cheaper. Regardless, they tend to stay enrolled rather than cancelling it. Odean says, “For a gym member to actually end their membership is to admit that they won’t exercise—that they give up. From an economist point of view, this is interesting because it is expensive to maintain this membership and to get no value out of the membership.”

Ходить в тренажерку поразово выходит дешевле из-за пропусков, однако не мотивирует.
