Despite extensive use of bargaining models in economics and despite Becker's insistence on the importance of altruism in families, the theoretical literature on bargaining ignores altruism and assumes that everyone is an egoist. This paper shows that incorporating altruism into cooperative...

We assess size and scope-related economies in the global advertising and marketing services business. A translog cost function is employed wherein a firm's costs vary according to its scale and two dimensions of the scope of its operations. Parameters of the model are estimated via three stage...
