a) Use the information in the table to calculate nominal GDP, real GDP, and the GDP deflator for each year, assuming that the base year is 2012.
b) What are the growth rates of real GDP between 2012 and 2013, and between 2013 and 2014?
a) Consider the following price indexes: 90 in 2009, 100 in 2010, 110 in 2011, and 121 in 2012. Answer the following questions.
i) What is the base year? How do you know?
ii) What is the inflation rate from 2009 to 2010?
iii) What is the inflation rate from 2011 to 2012?
iv) If the cost of the consumption basket in 2010 is $2,000, what is the cost of thesame basket of goods and services in 2009? In 2012?
b) Currently, the CPI used to calculate the inflation rate is equal to 90. The general expectation throughout the economy is that next year the value of CPI will be 94.5. The current nominal interest rate is 4.75 percent. What is the real interestrate?
Question 4
India is a ‘small country' in the world car market.
a) Assume that world car price is below the price that prevails in India. Does India gain by engaging in international trade in car? Does it export or import? Draw a diagram to show the gains (or losses) from trade. Who gains and who loses?
b) Suppose that a technological advance increases the domestic supply of cars in India.What effect does this advance have on the domestic price of car? Discuss a scenario in which the direction of trade changes. Using your graph from part (a), show the effect on consumer surplus, producer surplus, and total surplus in India. Who are thewinners and losers? Does free trade provide an incentive to the domestic car makers in India to innovate?
