Students have asked these similar questions
C is consumer expenditure
T is tax revenue
Y is aggregate output
I is investment expenditure
r is interest rate
G is government expenditure
L is money demand
M is money supply
Derive the relevant matrix inverse (do not use Cramer's rule) to solve for the equilibrium level of income in
terms of government expenditure (G). At what level of public spending does the government balance its
budget? (Hint: the endogenous variables are Y and r).
C = 450 + 0.4Y
I = 350
G = 150
X = 70
Z = 35 + 0.1Y
T = 0.15Y
Yf = 1550
Calculate the tax revenue to the government of this country when the economy remains in equilibrium.
Calculate what the new equilibrium income should be if the government of this country decides to cancel all taxes, implying the tax rate would now be 0%.
Before the government decreased the tax rate, how much of government
spending was required to bring the economy to full employment?
Suppose that the consumer’s consumption demand function is given by Cd = 0.8(Y−T)+10. Investment is Id = 20, government expenditure is G = 10, and tax is T = 10.
What is the equilibrium GDP (income)?
Suppose that government expenditure increases by 10 units while tax is unchanged. How will GDP change? What is the multiplier?
Suppose that government expenditure increases by 10 units while tax also increases by 10 units. How will GDP change? What is the multiplier?

The Research Director of the Ministry brought you the following data on Nigeria’s for the previous fiscal year, 2021. An examination of the data reveals that, during the fiscal year 2021, households in Nigeria saved 20% of their disposable income (Yd) and spent the rest on consumption. In addition, ₦5,000.00 was spent on Consumption expenditure (C), which is independent of income and Gross Private Investment (I) was ₦ 7,000.00. Total Government expenditure (G) which stood at ₦8,000.00 was supposed to be financed by a lump sum tax of ₦2,000.00 (independent of income) and a proportional tax rate of 25% of national income. Exports (X) stood at ₦2,500.00. In addition, the country’s import (M) during the previous fiscal year comprises of ₦1,000.00 which was independent of the country’s national income and 10% which was dependent of the country’s national income.
