Sometimes people are willing to behave cooperatively, without having a narrowly perceived economic incentive. An example is people's participation in recycling programs or the fact that people often consider greenhouse gas emissions an essential factor when buying a new car. In these cases, what is considered to be the 'correct thing to do' is an important factor in their decision. In this context, I introduced a model of cooperation, where the players partially follow Kant's Categorical Imperative (see the paper 'A Model for Partial Kantian Cooperation'). This kind of research is theoretically (or even philosophically) interesting, but can also have practical applications when trying to coordinate people's actions.
