After a boat rescues everyone else from Gilligan's Island, the Professor and Gilligan remain behind, afraid of getting shipwrecked again with the same bunch of people. The Professor grows coconuts and catches fish. Last year he harvested 1,250 coconuts and caught 1,750 fish. He values one fish as worth two coconuts. The Professor gave 250 coconuts to Gilligan in exchange for help in the harvest, and he gave Gilligan 175 fish in exchange for collecting worms for use in fishing. Gilligan consumed all his coconuts and fish. In terms of fish, the GDP of Gilligan's Island =

2,375 GDP is the value of all final goods and services produced during the year. The items to be included in GDP are the coconuts the Professor grows plus the amount of fish he catches, where the coconuts must be translated into units of fish at the rate of 2 coconuts per fish. GDP equals 1,250/2 +1,750 =2,375.

Consumption accounts for _______ of the GDP in the US

By Marks buys a one-year German government bond (called a bund) for $400. He receives principal and interest totaling $436 one year later. During the year the CPI rose from 150 to 162, but he had thought the CPI would be at 159 by the end of the year. By Marks had expected the real interest rate to be ________, but it actually turned out to be ________.

3%; 1%

If the expected inflation rate was 2.5%, the expected real interest rate was 4.0%, and the actual inflation rate turned out to be 3.2%, then the real interest rate equals

3.3%

If the expected inflation rate was 2.5%, the expected real interest rate was 4.0%, and the actual inflation rate turned out to be 3.2%, then the real interest rate equals

3.3% 2.5+4.0= 6.5- 3.2%= 3.3%

Nominal GDP in 1970 was $1,035.6 billion, and in 1980 it was $2,784.2 billion. The GDP price index was 30.6 for 1970 and 60.4 for 1980, where 1992 was the base year. Calculate the percent change in real GDP in the decade from 1970 to 1980. Round off to the nearest percentage point.

36% Real GDP= Nominal GDP/ GDP price index

Nominal government purchases were $2226.2 billion in 2008 and rose to $2372.8 billion in 2009. Real government purchases were $1940.6 for 2008 and $1958.0 for 2009, where 2005 was the base year. Calculate the percent change in the chain-weight price index for government purchases (rounded to the nearest percentage point) from 2008 to 2009.

Monica grows coconuts and catches fish. Last year she harvested 1500 coconuts and 600 fish. She values one fish as having a worth of three coconuts. She gave Rachel 300 coconuts and 100 fish for helping her to harvest coconuts and catch fish, all of which were consumed by Rachel. In terms of fish, Monica's income would equal

900 fish

Which of the following is included in U.S. GDP?

A newly constructed house.

Loretta agrees to lend Ted $500,000 to buy computers for his consulting firm. They agree to a nominal interest rate of 8%. Both expect the inflation rate to be 2%. (a) Calculate the expected real interest rate. (b) If inflation turns out to be 3% over the life of the loan, what is the real interest rate? Who gains from unexpectedly high inflation, Loretta or Ted? (c) If inflation turns out to be 1% over the life of the loan, what is the real interest rate? Who gains from unexpectedly low inflation, Loretta or Ted?

Answer: (a) 8% - 2% = 6%. (b) 8% - 3% = 5%. Ted gains from unexpectedly high inflation, because he repays the loan with dollars that aren't worth as much as was expected. (c) 8% - 1% = 7%. Loretta gains from unexpectedly low inflation, because she gets repaid with dollars that are worth more than was expected.

Which of the following is included in U.S. GDP? A. The purchase of a watch from a Swiss company. B. A newly constructed house. C. The sale of a new car from a manufacturer's inventory. D. The sale of a used car.

In terms of fish, the income of the Professor is ___, and the income of Gilligan is ___

Gilligan's income is easily calculated, as long as you convert to fish. It equals 250/2 + 175 =300. To find the Professor's income, be sure to remember that anything he pays Gilligan is not his income. So the Professor's income = (1,250−250)/2 +(1,750−175) = 2,075. Remember that wages paid and other inputs to production can't be part of the Professor's income.

Which of the following equations describes the government deficit?

G + TR + INT − T

Which of the following is not a category of consumption spending in the national income accounts?

In the country of Kwaki, people produce canoes, fish for salmon, and grow corn. In one year they produced 5000 canoes using labor and natural materials only, but sold only 4000, as the economy entered a recession. The cost of producing each canoe was $1000, but the ones that sold were priced at $1250. They fished $30 million worth of salmon. They used $3 million of the salmon as fertilizer for corn. They grew and ate $55 million of corn. What was Kwaki's GDP for the year?

Inventories are valued at the cost of production, so the 1000 canoes in inventory were valued at $1000 each, for a total of $1 million. Four thousand canoes at $1250 each totaled $5 million. Salmon as a final good were worth $27 million (the other $3 million were used up as an intermediate good), and corn worth $55 million was grown. So total GDP (in millions) was $1 + $5 + $27 + $55 = $88 million.

It is discovered that businesses bought $6 billion more furniture than previously thought. This furniture was manufactured in North Carolina during the current year.

GDP deflator=

Nominal GDP/ Real GDP

What is the difference between nominal and real economic variables? Why do economists tend to concentrate on changes in real magnitudes?

Nominal variables are in units of money, while real variables are in physical quantities of output. We measure nominal variables using current market prices and real variables using market prices in a given base year. Nominal variables may increase, but you don't know if the increase is due to higher prices and the same quantity, or a higher quantity with unchanged prices; real variables reflect just quantity changes. For the most part, real variables (consumption, investment, and the capital stock) affect each other in the economy, with lesser roles played by nominal variables (money supply, and price level).

to what extent are homemaking and child-rearing accounted for in the government's GDP accounts?

Only to the extent that they are provided for pay

The percentage change in nominal GDP is calculated as [(current nominal GDP minus− base year GDP)/base-year GDP] times × 100%

Real interest rate formula

The real interest rate equals the difference between the nominal interest rate and the actual rate of inflation nominal-actual= real
