Government saving is defined as T- (G+TR+INT).

Here, G includes both govt. consumption and govt. investment. But ideally, we should not include investments while calculating savings.

But even if we do not separate the two components out of G, we get the same answer, i.e., both the definitions of uses-of-savings identity hold true. (The difference arises only because of some statistical discrepancies)

It would indicate that govt. investments are nil. Why does this happen?

A dozen eggs cost $0.88 in January 1980 and $2.11

in January 2015. The average wage for production

workers was $7.58 per hour in January 1980 and

$19.64 in January 2015.

a. By what percentage did the price of eggs rise?

b. By what percentage did the wage rise?

c. In each year, how many minutes did a worker

have to work to earn enough to buy a

dozen eggs?

d. Did workers’ purchasing power in terms of eggs

rise or fall?

The chapter explains that Social Security benefits are

increased each year in proportion to the increase in

the CPI, even though most economists believe that the

CPI overstates actual inflation.

a. If the elderly consume the same market basket

as other people, does Social Security provide the

elderly with an improvement in their standard of

living each year? Explain.

b. In fact, the elderly consume more healthcare com-

pared to younger people, and healthcare costs

have risen faster than overall inflation. What

would you do to determine whether the elderly

are actually better off from year to year?

Consider an economy with a different levels of aggregates as follows: c=0.8(1-t)Y t=0.25 I=900-50r G =800 L=0.25y-62.5r money supply: M=1000 price level :p=2 a) derive the IS and LM equation b) determine the equilibrium levels of income and interest rate c) calculate the government spending multiplier d)By how much income and interest change for a unit change in government spending? e) determine the amount of ''crowd out'' and interpret it

For the year Y, for five countries, one has the following information: GDP (X) = 850 000 currency X / GDP (Y) = 300 000 currency Y / GDP (Z) = 1 500 000 currency Z / GDP (T) = 725 000 currency T / GDP (W) = 1100000 currency W. Basket of products with identical products over the five economies - Basket of Products = 1.25*A + 3.5*B+2*C. Country X (prices in currency X) (Products: A / B / C): 14 / 19 / 21. Country Y (prices in currency Y) (Products: A / B / C) 25 / 32 / 39. Country Z (prices in currency Z) (Products: A / B / C) 8 / 13 / 19. Country T (prices in currency T) (Products: A / B / C) 11 / 16/ 23. Country W (prices in currency W) (Products: A / B / C) 17 / 19 / 26. The correct answer is:a.The value of GDP of country Y in currency X at PPP is 220847 and represents 36.10% of GDP of country X

The value of GDP of country Y in currency X at PPP is ?????? and represents ????%
