Assume a machine that has a useful life of only one year costs $2,000. Assume, also, that net of such operating costs as power, taxes, and so forth, the additional revenue from the output of this machine is expected to be $2,200. The expected rate of return on this machine is Multiple Choice O 10 percent. O 20 percent O 30 percent. O 2 percent.If the MPC is 0.5 and the equilibrium GDP is $40 billion below the full-employment GDP, then the size of the recessionary expenditure gap is Multiple Choice $20 billion. O $40 billion. O $60 billion. O $80 billion.If the MPC in an economy is 0.75 and aggregate expenditures increase by $8 billion, then equilibrium GDP will increase by Multiple Choice O $32 billion. O $2.75 billion. O $6 billion. O $40 billion.If the MPC in an economy is 0.75, government could close a recessionary expenditure gap of $300 billion by cutting taxes by Multiple Choice O $400 billion. O $300 billion. O $75 billion. O $225 billion.If inyeatmerrt decreases by $8 billion and the economy's MPC is 0.6. the aggregate demand curve will shift Multiple Choice 0 leftward by $20 billion at each price level. rightward by $8 billion at each price level. leftward by $4 billion at each price level. 0 rightward by $20 billion at each price level. If the multiplier in an economy is 3, a $10 billion increase in net exports will Multiple Choice O increase GDP by $30 billion. O reduce GDP by $6 billion. O decrease GDP by $30 billion. O increase GDP by $10 billion.Suppose that an economy produces 3,000 units of output, employing 100 units of input, and the price of the input is $30 per unit. The level of productivity in this economy is Multiple Choice O 30. O 10. O 20. O 40.If investment increases by $20 billion and the economy's MPC is 0.75, the aggregate demand curve will shift Multiple Choice O rightward by $80 billion at each price level. O rightward by $20 billion at each price level. O leftward by $80 billion at each price level. O leftward by $60 billion at each price level.Input Quantity Real Domestic Output 100 200 150 300 200 400 The table gives information about the relationship between input quantities and real domestic output in a hypothetical economy. If the price of each input is $3, the per-unit cost of production in the economy is Multiple Choice O $1.50. O $0.65. O $0.30.If a lumpsum income tax of $35 billion is levied and the MP8 is 0.4, the consumption schedule will shift Multiple Choice 0 downward by $21 billion. upward by $21 billion. downward by $14 billion. 0 downward by $35 billion. Suppose that real domestic output in an economy is 144 units, the quantity of inputs is 12, and the price of each input is $4. The level of productivity is Multiple Choice O 12. O 144. O 10. O 24.Suppose that an economy produces 500 units of output. It takes 10 units of labor at $15 a unit and 2 units of capital at $50 a unit to produce this amount of output. The per unit cost of production is Multiple Choice O $0.50. O $2.00. O $1.00. O $0.20.If the inflation rate is 5 percent and the real interest rate is 6 percent, the nominal interest rate is Multiple Choice O 11 percent. O 1 percent. O 0 percent. O 5 percent
