The document summarizes key factors in analyzing economic growth in BRIC countries over the past 10 years and projections for the future: 1) Labor force growth is estimated using UN projections for growth in the working age population between 15-64 years old. 2) Capital accumulation is modeled as each country investing at a constant rate over time based on starting capital proportional to output. 3) Technical progress and productivity growth is modeled as countries converging to the technological frontier, currently assumed to be the US, through a combination of potential and conditions.
