9. The per capita real GDP is usually a better measure of the economic well-being in a country than the real GDP itself. If the real GDP of an economy grows by 6% and the population grows by 2%, the per capital real GDP will grow approximately by (a) 2% (b) 3% (c) 4% (d) 8% 10. When consumers substitute cheaper goods for those that have risen in price, (a) the GDP deflator overstates the inflation. (b) the GDP deflator understates the inflation. (c) the CPI overstates the inflation. (d) the CPI understates the inflation. 11. Suppose that during a year a significant portion of the consumption basket of the typical consumer in an economy consists of goods that were produced in the previous year. In calculating the inflation rate using the CPI versus the GDP deflator, (a) the CPI approach overstates the inflation rate compared to the GDP deflator ap- proach. (b) the CPI approach understates the inflation rate compared to the GDP deflator approach. (c) the CPI approach and the GDP deflator approach give the same measure of inflation rate. (d) the CPI approach and the GDP deflator approach give different measures of infla- tion rate, but we cannot tell without further information which one overstates or understates the other
