Following the lead given by new institutional economics, we shall take the transaction as our unit of analysis. For our purposes, a transaction can be thought of as any act of social exchange that depends on information flows for its accomplishment. Transactions can be as simple and brief as the purchase of a packet of cigarettes, or as complex as and extended as those which bind a Zen master to his disciples. Like institutional economists, we are interested in the relationship that can be established between different transactional characteristics and the phenomenon of institutionalization. Our use of the term transaction, however, will extend beyond that of institutional economics where the focus has tended to be primarily on transaction costs and efficiency considerations. These, to be sure, are relevant. But, as we shall see, they are not the whole story.
