This paper proposes a setting that allows for technological cooperation in the cost sharing model. Dealing with discrete demands, we study two properties: Additivity and Dummy. We show that these properties are insuffcient to guarantee a unit-flow representation similar to that of Wang (1999)....

In the cost sharing model with technological cooperation, we investigate the implications of a number of consistency requirements. In a context where the enforcing authority cannot prevent agents from splitting or merging their demands (in order to reduce their cost shares), the methods used...
