* * * * * * Again, the growth rate of real GDP from one year to the next is the answer to this question: “How much would GDP (and hence everyone’s income) have grown if there had been zero inflation?” This is why real GDP is corrected for inflation. * * * The data in the table are for a hypothetical economy that produces two final goods, A and B. For all parts of this problem, use 2007 as the base year. If you’re running short on time, you can skip part A – it’s the least challenging. If you only have time for one of the three, you might skip A and B, as C by itself covers all of the material: it requires students to compute nominal and real GDP before they can compute the GDP deflator. * * * * Most economists, policymakers, social scientists, and businesspersons use a country’s real GDP per capita as the main indicator of the average person’s standard of living in that country. * * Very scathing words, indeed! * * Then why do we care about GDP? Because a large GDP does in fact help us to lead a good life. GDP does not measure the health of our children, but nations with larger GDP can afford better health care for their children. GDP does not measure the beauty of our poetry, but nations with larger GDP can afford to teach more of their citizens to read and enjoy poetry. GDP does not take account of our intelligence, integrity, courage, wisdom, or devotion to country, but all of these laudable attributes are easier to foster when people are less concerned about being able to afford the material necessities of life. In short, GDP does not directly measure those things that make life worthwhile, but it does measure our ability to obtain the inputs into a worthwhile life. * This figure and the two that follow are from the data in Table 3 of the textbook.
