What is the Government Spending Func, In Macroland, autonomous consumption equals 100, the marginal propensity to consume equals 0.75, net taxes are fixed at 40, planned investment is fixed at 50, government purchases are fixed at 150, and net exports are fixed at 20. (Round your answers to 4 decimal places.) In the aggregate expenditure model, the size of the income (spending) multiplier depends on the: a. $1,000 $1,500 For the economy as a whole, macroeconomic equilibrium occurs where total spending, or aggregate expenditure, equals total production, or GDP: Aggregate Expenditure = GDP. To know more check the A) Write the mathematical expression of the consumption function. Annual Cost What is the consumption, Suppose a closed economy has an aggregate consumption function given by C = 300 + 0.75Yd and generates $2000 output and income in equilibrium. While there are many things that can influence the level of investment in the economy other than the real interest rate, we will discuss only three. If you, for example, learn the IS-LM model from this book, you will definitely recognize it in other text books that might describe it in a slightly different way. $1,000 At what level of income is savin, Suppose you are given the following consumption and income data: |Consumption |100 |190| 280| 370 |460 |550 |Income| 0 |100 |200 |300| 400 |500 Obtain an equation for the consumption function. the Keynesian spending multiplier is? $1,000b.
