Abstract: In this paper we characterize the optimal steady state and dynamics of an intertemporal economy in presence of endogenous fertility. For doing this we propose a new version of Critical Level Utilitarianism (CLU) a là Blackorby et al (1995), that we call Relative CLU, which is shown to be axiomatically founded and allows for time-varying critical level. In particular, we show that under such social preferences both the short and the long run effects of technological shocks on the optimal population growth are non-trivial, depending on the characteristics of both preferences and production technology. However, we show that the negative relationship between fertility and technological development emerges under a broad class of preferences, which is typically found in empirical research.
