Framing effects describe situations in which the same set of options lead to different choices and behaviors due to how the problem is presented. Specifically, for this research, I analyze situations with people interaction (hence, social preferences / prosocial behavior) over the same set of options but presented in different ways. These ways might be, for example, different market structures, the use of suggestions, or various explicit incentives. Such analysis is used to understand different contexts. For example: the power of recommendations (how people are affected by simple suggestions that do not change the original task). The role of social labels (how people adjust their behavior by naming their role in different ways?). Or the crowding out of intrinsic motivation (how the use of explicit incentives influences people's perception and might deteriorate their social responsibility).
