Description Political actors often interact spatially, and move around. However, with a few
exceptions, existing political research has analyzed spatial dependence among actors
with fixed geographic locations. Focusing on fixated geographic units prevents us
from probing dependencies in spatial interaction between spatially dynamic actors,
which are common in some areas of political science, such as sub-national conflict
studies. In this note, we propose a method to account for spatial dependence in
dyadic interactions between moving actors. Our method uses the spatiotemporal
histories of dyadic interactions to project locations of future interactions—projected
actor locations (PALs). PALs can, in turn, be used to model the likelihood of future
dyadic interactions. In a replication and extension of a recent study of subnational
conflict, we find that using PALs improves the predictive performance of the model
and indicates that there is a clear relationship between actors’ past conflict locations
and the likelihood of future conflicts.
