Population - EPPA
Population is an exogenous input for EPPA. It can enter the model in two forms: total population and working age population. While the welfare measuring is based on total population, in a special version of EPPA that focuses on the health impact of air pollutants exposure, the working age population is used for air pollution health effects calculation that affects the available labor input  . For each region, the labor input is assumed to change proportional to the population, and the labor input affects the dynamics of other macroeconomic production factors (capital, energy) since the model seeks an optimal allocation of production factors. For the version 6 of EPPA, population data come from the World Population Prospects: The 2012 Revision (United Nations, 2013) .
