This is kind of tangential to the submission, but I just read through the "Israeli day-care" paper[1], and thought it was quite interesting. The existence of the fine clearly shifted the equilibrium, but I wonder whether or not the introduction of the fine partway through the start of the year contributed anything to the increase of late parents. Redoing the experiment with the addition of a third group of daycare centers, where the fine is specifically laid out at the beginning of the year, might shed some insight into that?
