Understanding Declining Mobility and Inter-Household Transfers among East African Pastoralists
22 Pages Posted: 27 Apr 2009
We model inter-household transfers between nomadic livestock herders as the state-dependent consequence of individuals' strategic interdependence, resulting from the existence of multiple, opposing externalitiesmore specifically, a public-good security externality among individuals sharing a social (e.g. ethnic) identity in a potentially hostile environment, and a resource appropriation externality related to the use of common property grazing lands. Our model augments the extant literature on transfers, and is more consistent with the limited available empirical evidence on heterogeneous and changing transfers' patterns among east African pastoralists. The core principles of our model possibly apply more broadly, for example to long-distance migrants or even foot soldiers in street gangs.
