Much of my time in the field was taken up with attempts to discover the details and history of individual partnerships between individual men in moka transactions which ranged clans and whole tribes in relations with each other. From the material which I gathered it is possible to raise, and partially to answer, a number of questions: what is the extent of participation in group moka by adult men? What are the affinal and cognatic ties between the men involved? Do men exchange also with unrelated partners, as they do among the Enga? Is there heavy investment in affines by comparison with other categories of partner?

In particular, details of participation in moka can help us to assess the importance of big-men. Are the big-men more prominent as donors and recipients than others? Is there a distinction between major and minor big-men? Do big-men's partnership networks differ from those of others? That is, do they give to more partners, do they give more to unrelated partners, do they invest heavily in their affines, and so on?

The overall size of moka prestations, the numbers of partnerships activated in them, and the prominence within them of big-men vary to some extent in accordance with the political context in which they take place.
