α: calibrated so average coauthorship-adjusted count equals average raw count
In this paper, we prove the existence of a stationary equilibrium in an intergenerational stochastic game with non-paternalistic altruism as defined by Ray (1987). Our approach is based on the assumption that the transition probabilities are non-atomic. The utility function of each generation has a very general form including many special cases studied in the literature.
