For this purpose, we introduce reference-dependent utility into an OLG model of an industrial cluster where agents allocate resources between consumption and knowledge investments and where the latter spills over to the rest of the cluster. It is shown that if the agents in the cluster have altruistic preferences, they will internalize the externalities from knowledge investments and create more knowledge than if they were atomistic or considered their neighbors to be rivals.15 pages240748 bytesapplication/pdfenindustrial cluster; reference-dependent utility; knowledge spillovers; relative consumptionReportEconomics
