Consider an economy described by the following equations: Y = C+I+G C = 150 + 0.6 x (Y - T) I = 500 – 50 x r G = 200 T = 150 where Y is GDP, C is consumption, I is investment, G is government purchases, T is taxes, and r is the interest rate. If the economy were at fl employment (that is, at the natural rate of output), GDP would be $1,400. Identify the equation(s) each of the following statements describes. Check all that apply. Statement C T It is an autonomous amount, independent of other factors. It is a function of disposable income. It depends on the interest rate. The marginal propensity to consume in this economy is Suppose the central bank's policy is to adjust the money supply to maintain the interest rate at 2%, so r = 2. When the interest rate is 2%, GDP is S GDP at an interest rate of 2% is the full-employment level.

What is the relationship of the GDP deflator to real GDP? To make comparisons across time or across borders, one must use the notion of a GDP deflator to convert nominal GDP into real GDP for comparisons. Nominal variables are in current dollars and have price level changes such as inflation and deflation included in them. Real variables are in constant dollars due to the factoring out of price level changes using a base year and a deflator. What is the current nominal GDP for the US economy? What is the current real GDP for the US economy?
The following table contains data for a hypothetical closed economy that uses the dollar as its currency. Suppose GDP in this country is $1,540 million. Enter the amount for government purchases. National Income Account Value (Millions of dollars) Government Purchases (GG) Taxes minus Transfer Payments (TT) 455 Consumption (CC) 700 Investment (II) 490 Complete the following table by using national income accounting identities to calculate national saving. In your calculations, use data from the preceding table. National Saving (S)National Saving (S) = = (y-t-g, g-t, y-c, y-c-g) = = (C,G,Y,I) $ ______million
Which of the following is true about the components of GDP? When we buy stocks, this is economic investment. Net exports must always be a negative number. Government purchases make up the largest part of GDP. A refrigerator is a durable consumption good.
The following graph shows the market for loanable funds in a closed economy. The upward-sloping orange line represents the supply of loanable funds, and the downward-sloping blue line represents the demand for loanable funds. Supply 5 Demand 1 100 200 300 400 500 600 LOANABLE FUNDS (Billions of dollars) is the source of the supply of loanable funds. As the interest rate falls, the quantity of loanable funds supplied Suppose the interest rate is 3.5%. Based on the previous graph, the quantity of loanable funds supplied is than the quantity of loans ▼ of loanable funds. This would encourage lenders to the interest rates they charge, thereby demanded, resulting in a the quantity of loanable funds supplied and the quantity of loanable funds demanded, moving the market toward 0% the equilibrium interest rate of INTEREST RATE (Percent)
In the first quarter of 2020, US real GDP declined about 9%, due to the economics shocks from the Covid 19 virus. If prices were completely flexible, and this means all prices, both inputs (such as labor), as well as output prices, what would you think would have been the drop in GDP? If prices are completely fixed, would the drop in GDP be greater or less than the flexible case? Why? If the Expenditure method of accounting for GDP, has to equal the Income Side, and the economy overproduces a particular item, say automobiles, the income side will also be higher, workers will buy the extra cars with extra income and the economy can gyrate indefinitely higher? Why or why not?
