Have the stocks and flows of hunter-gatherer economies been formally analysed? A lot of work in economic anthropology seems to be about allocation mechanisms. This feeds into economic discourses about the institutions governing markets and non-market alternatives, e.g. Douglas North (1977):
Markets and Other Allocation Systems in History: The Challenge of Karl Polanyi

It is reasonable to assume that the forces that lead to the
substitution of firms for markets today may also help us to explain
the variety of forms of economic organisation in past societies.

I wonder if similar work has been done on stocks and flows, i.e. a formal economic analysis of stocks (e.g. rights to access common land, its fruits once harvested, services such as healthcare, tools, artefacts) and flows (e.g. reciprocity mechanisms, both within and between groups).
There is ample qualitative analysis, e.g. in this volume edited by John Gowdy (1997) which includes a contribution by Marshall Sahlins (Stone Age Economics, 1972):
Limited Wants, Unlimited Means: A Reader On Hunter-Gatherer Economics And The Environment
I wonder if there have been attempts to formalise the stocks and flows?
Anthropology is concerned with understanding a society in qualitative terms rather than quantitative terms. To try to understand it in these terms is to misconceive how those societies work and what anthropology is.
