Historic GDP growth rates and projections until 2017 are taken from the IMF (International Monetary Fund World Economic Outlook Database). The database provides data for all the model countries and the exogenous countries Algeria, Belarus, Russia and Ukraine. For YU (the countries of former Yugoslavia) the average of Serbia and Croatia has been used, and for ROW (rest of the world) the growth in GDP for the rest of the world.
Historic GDP growth rates from 2009 to 2012 and projections from 2012 to 2017 are used. For 2018 to 2030 World Bank projections for GDP growth have been used for all countries. From 2030 to 2050 World Bank projections of population growth are used, along with an assumption of a gradual reduction in GDP per capita growth rates towards 1% p.a. from 2030 to 2050.
