Optimal consumption of polluting and non-polluting goods: The role of habits
نویسنده
چکیده
We present a basic exogenous growth model with two consumption goods that differ as regards their contributions to environmental pollution. Allowing for habit formation of the polluting good, we show under which conditions habit formation raises the consumption of the clean good relative to the dirty one in the competitive economy. Further, we demonstrate when habit formation generates a lower steady-state pollution stock compared to the situation without habits. Finally, we determine the Pigou tax rates and we illustrate that the social optimum may imply a higher steady-state pollution than the competitive economy if the habit formation is sufficiently strong.

متن کاملOptimal recycling under heterogeneous waste sources and the environmental Kuznets curve
We investigate how the relationship between economic growth and pollution is affected by the source of pollution: production or consumption. We are interested in polluting waste that cannot be naturally absorbed, but for which recycling efforts aim to avoid massive pollution accumulation with harmful consequences in the long run. We distinguish the cases where recycling efforts are capital-impr...
