We assume consumption function takes the linear form: » (a) the change of consumption when income increases from 3 million to 4 million. • (b) the change of consumption when income increases from 20 million to 21 million. Question: Is (a) equal to (b)?

Suppose that an economy consists of only two individuals. Jeremy has $1150 available to spend on goods. He decides to purchase $750 worth of produce from Michele in the current month. No other economic activity takes place during the current month. Using this information, answer the questions. For the current month, what is the economy's income? $ For the current month, what is the economy's expenditure? $ In an economy, how are income and expenditure related? O Income is less than expenditure. Income is greater than expenditure. They are unrelated. O They are equal.

The letters Y, C, S, and /are used to represent real GDP, consumption, saving, and Investment, respectively. The equation representing the Investment schedule for the economy is O Multiple Choice 1=0.3Y /= 80-03Y =30+0.1Y 10-30

(a) Assume Consumption (C) is given by the equation C = 500 + 0.6(Y – T). Taxes (T) are equal to 600. Government spending is equal to 1,000. Investment is given by the equation I = 2,160 – 100r, where r = the real interest rate = 13 percent. In this case, what is the equilibrium Gross Domestic Product (GDP)/Total output (Y)/Total income? How does the equilibrium income change if government designs and executes expansionary fiscal policy? Show graphically and mathematically.
