In the circular flow of income, which of the following is classified as an injection into the economy?

In the circular flow of income, if an economy's total injections (\(I + G + X\)) are less than its total withdrawals (\(S + T + M\)), which of the following is the most likely outcome?

In an open economy with a government sector, the marginal propensity to consume (\(MPC\)) is \(0.8\), the marginal propensity to tax (\(MPT\)) is \(0.1\), and the marginal propensity to import (\(MPM\)) is \(0.1\). Calculate the value of the multiplier.

According to the Keynesian view of the Long-Run Aggregate Supply (LRAS) curve, what happens when Aggregate Demand (AD) increases while the economy is operating in the horizontal section of the curve?

The following data represents an economy's circular flow (in \(\$bn\)):
Savings (S) = \(40\)
Taxation (T) = \(60\)
Imports (M) = \(50\)
Investment (I) = \(35\)
Government Expenditure (G) = \(75\)
Exports (X) = \(45\)
Based on this data, what is the net impact on the level of national income?

Define the term national wealth and distinguish it from national income.

Calculate the value of the multiplier (\(k\)) if the marginal propensity to save (MPS) is \(0.15\), the marginal propensity to tax (MPT) is \(0.2\), and the marginal propensity to import (MPM) is \(0.05\).

In the circular flow of income for an economy, money flows between different sectors.
(a) Distinguish between income and wealth.
(b) Explain the impact on the equilibrium level of national income when the value of total injections is greater than the value of total withdrawals.
