Socio-economic drivers - WITNESS

The socio- economic drivers of WITNESS encompasses Population and Social acceptability (not yet integrated in the mainstream stable version).

Population is an endogenous model in WITNESS (see specific documentation).

Economic activity is directly processed in the Macro-economy model (see specific documentation).

Net productivity (function of capital, energy, labor and damages) minus Investments (including investments for energy production, carbon capture…) define Consumptions (all what is produced and not used for invesment 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.

Note: The documentation of WITNESS is 'in preparation' and is not yet 'published'!
