Socio-economic drivers - WITNESS
The socio- economic drivers of WITNESS encompasses Population and Social acceptability (the later not yet integrated in the mainstream stable version).
Population is an endogenous model in WITNESS. The model is based on McIsaac (2017)1 with some modifications. First, the model is run on a one year time step instead of a five year time. Then, the population is divided in one year age groups instead of five year age range groups. Lastly, the birth rate equation has been modified by adding the influence of education on the number of children. (see specific documentation).
Economic activity is directly processed in the Macro-economy model (see specific documentation), with the Net Productivity (function of capital, energy, labor and minored by damages) minus Investments (including investments for energy production, carbon capture…) define Consumptions (all what is produced and not used for investment is consumed).
For regional aspects, the GDP distribution model is a predictive model developed to estimate the distribution of Gross Domestic Product (GDP) adjusted to Purchasing Power Parity (PPP) among different countries over time.
The Macro-Economy model is that way aiming to provide insights into the future GDP-PPP adjusted distribution based on the computed GDP-PPP adjusted in the macroeconomics discipline.
