Demography and pollution

In this paper, we consider an OG model with endogenous fertility and pollution externalities. We assume that pollution lowers the productivity. In the long run, under dominant income (substitution) effects, a raise in the cost of rearing children, increases (decreases) consumption and decreases (increases) pollution. In the short run, under dominant income effects, a sufficiently low pollution elasticity of labor productivity promotes deterministic cycles through a Hopf bifurcation jointly with expectations-driven fluctuations.
