Continuous time in models where a common property resource stock is exploited simultaneously by N agents, and in particular their Stationary Markov perfect Nash equilibria, have been widely studied in literature under diﬀerent sets of hypotheses. Here we treat the case of a resource which is distributed in space and mobile through the entire territory (such as a ﬁsh population or a transboundary oil deposit). As a spatial support we consider a generic ﬁnite simple graph, where we specify productivity at each node. We also assume that the diﬀusion process follows Fick’s ﬁrst law among connected nodes, and we specify for each arc the “intensity” of the connection. We characterize internal linear Markov Nash equilibria for the dynamic game of N symmetric players having the same isoelastic utility. We show how they depend on the structure of the graph and we describe the eﬃciency of the related spatial public policies.
