ABSTRACT
Information and knowledge behave in very different ways to most products or simple services. For example, if you transfer knowledge to a client-or even many clients-you still have that knowledge, and in fact probably more than you started with. Very importantly, there is often little relationship between the cost of inputs and the value of knowledge outputs. And much attention has been paid to how knowledge is often subject to increasing returns rather than diminishing returns: it can increase in value the more it is shared.1
