Fill in the third blank.
Italy is a relatively rich country with per-capita GDP of $28,000. India is a relatively poor with per-capita GDP of only $3,500. However, India is growing rapidly at a growth rate of 5% per year. We want to find how many years it will take for India’s per capita GDP to equal Italy’s current per-capita GDP of $28,000.
How many times must India's per-capita GDP double in order to reach Italy's per-capita GDP?
India's per-capita GDP must double __________ times.
Use the rule of 70 to find how many years it will take for India's per-capita GDP to double once at a 5% growth rate.
Doubling time: ______________________ years

According to World Bank data, in 1985, Japan’s GDP was $3.67 trillion, and its annual growth rate was 6.33 percent. The GDP in this problem is in constant 2010 dollars. Assuming an exponential annual growth rate of 6.33 percent, calculate Japan’s projected GDP in 2010. In fact, Japan’s 2010 GDP was $5.7 trillion. What could explain any discrepancy between this number and your answer to part (a)?arrow_forwardWhich of the following is a true statement? Multiple Choice Economists who support economic growth say that it is the most practical route to the higher standards of living that the vast majority of people desire. Most economists believe that the recent rise in the average rate of productivity growth implies an end to the business cycle. Most economists believe that increases in real GDP actually produce decreases in overall economic well-being because of spillover costs. Mainstream economists disagree as to whether the rate of productivity growth was higher between 1995 and 2012 or between 1973 and 1995.arrow_forward
