\f(b) [25 points] Real GDP (at chained PPPs), Y PP, measures a country's GDP at international prices (common across countries) instead of national prices, making these measures of GDP comparable across countries. Compute real GDP (at Y, PPP chained PPPs) per capita, y, as: y PPP _ Pt for each country. Compute output per capita in country i relative to that of PPP the US as Rely VPPP = yt.i ,PPP yt,USA b.1. Plot relative output per capita for country i, Rely, PP. The graph should have time on the x-axis and Rely on the y- axis. Submit this graph (you don't need to submit any data). b.2. Briefly relate the behavior of Rely to the basic development observations discussed in class
