Presenter Rodica Ianole-Calin Abstract This paper examines the effect of build environment regulations for facades emergency repairs and beautification implemented by Cluj-Napoca, the second biggest municipality in Romania, in 2016. The scope was to identify if and how this intervention design could be slightly modified to be more effective by encouraging pro-social behavior and minimizing homeowners’ resentment. The empirical strategy was a qualitative method, based on structured-interview data collected from the sample of 47 homeowners that underwent retrofitting works, targeted by the policy. The results point to the need for further research in the form of field experiments focused on exploring a pro-social incentive mechanism design that captures responder’s behavior patterns.
