Why are changes in inventories included as part of investment spending? Suppose inventories declined by $1 billion during 2008. How would this affect the size of gross private domestic investment and gross domestic product in 2008? Explain.
In an economy of a specific country, the economy's consumption schedule is given in the table below. GDP=DI C 6500 6680 6800 6840 7000 7000 7200 7160 7400 7320 7600 7480 7800 7640 8000 7800 Use the above table information to answer the questions of part 1: Part 1: 1. If disposable income were $7800, how much would be saved? 2. What is the "break-even" level of disposable income? 3. What is this economy's marginal propensity to consume? 4. What is the average propensity to consume when disposable income is $7000? When disposable income is $8000? Part 2: 5. Suppose a $100 increase in desired investment spending ultimately results in a $300 increase in real GDP. What is the size of the multiplier? 6. If the MPS is .4, what is the multiplier? 7. If the MPC is .75, what is the multiplier? 8. Suppose investment spending initially increases by $50 billion in an economy whose MPC is 2/3. By how much will this ultimately change real GDP?
