SD.20.005 – Economic model for a sustainable planet (draft title))

Route: Sustainable development goals for inclusive global development

Cluster question: 001 How many people can the Earth sustain?

Reyer Gerlagh studies the global ‘Economics of Scale’. Increasing the number of people reduces natural resource available per person, leading researchers as Malthus 1809 and Hardin 1968 worry that the continued population growth would lead the world into poverty. On the other hand, economists such as Kuznets 1960 and Simon 1981 argued that people add to the solution of scarcity problems, by adding to the pool of ideas. Added to these grand aggregate economies of scale, there is the issue of distribution. Most of the environmental footprint is caused by a relatively small share of high-income world citizen, also living in developing countries. I would like to develop theory, empirical, and quantitative model to provide an assessment of the consequences of the current demographic patterns and policies to address concerns. I have ample experience with quantitative integrated models used for simulations and policy recommendations. I have both developed own integrated models and worked with models developed by others. I am also experienced with CGE models and empirical (econometric/statistical) models. I have contributed to policy-oriented projects, and published results of both academic and applied research in a variety of journals, from broad natural sciences journals to field journals and broad economic journals.
