We derive the Green Golden Rule (GGR) in the Habit Formation (HF) and Anticipation
of Future Consumption (AFC) frameworks. Since consumption is the key variable of GGR,
time non-separabilities in preferences over consumption streams, given by the AFC
and HF, may have important impacts on the environment and sustainability. We demonstrate
that agents who smooth their consumption patterns, according to the HF hypothesis,
are more likely to preserve the environment than those who anticipate future consumption
or who do not so smooth consumption. (C) 2018 Elsevier B.V. All rights reserved.
