Circular Flow of Income

In a four-sector open economy, national income equilibrium is maintained when total leakages (withdrawals) equal total injections. If savings ($S$) is \$150 million, taxation ($ T $) is \$100 million, imports ($ M $) are \$80 million, investment ($ I $) is \$180 million, and government expenditure ($ G $) is \$110 million, what is the required value of exports ($ X$) to maintain equilibrium?

Match each national economic transaction with its correct flow classification within the open four-sector circular flow of income model.

In a closed three-sector economy consisting of households, business firms, and the government, planned household savings ($S$) is $\$65\text{ billion}$, net government tax revenue ($T$) is $\$35\text{ billion}$, and private investment expenditure ($I$) is $\$45\text{ billion}$. For the circular flow of income to be in equilibrium, what must be the level of government expenditure ($G$)?

In an open four-sector economy, the circular flow of income is in equilibrium when total leakages (withdrawals) equal total injections. If planned savings ($S$) is $\$80\text{ million}$, imports ($M$) are $\$45\text{ million}$, planned investment ($I$) is $\$95\text{ million}$, government expenditure ($G$) is $\$60\text{ million}$, and exports ($X$) are $\$40\text{ million}$, what is the required value of government tax revenue ($T$) in millions of dollars?

Match each circular flow component or stream in a four-sector economy with its correct economic description.

In a four-sector open economy, circular flow equilibrium requires that total leakages ($S + T + M$) equal total injections ($I + G + X$). If domestic investment ($I$) increases by $\$40\text{ billion}$, government spending ($G$) decreases by $\$15\text{ billion}$, exports ($X$) rise by $\$25\text{ billion}$, tax revenues ($T$) increase by $\$20\text{ billion}$, and imports ($M$) remain constant, what change in household savings ($S$) is required to maintain equilibrium?

In the circular flow of income model for a simple two-sector economy comprising households and firms, interactions generate both real flows and money flows between the two sectors. Which of the following correctly identifies a real flow directed from households to firms?

Match each market component or sector flow in the circular flow of income with its correct functional economic description.

In a closed three-sector economy comprising households, business enterprises, and the government, national income is in equilibrium when total leakages equal total injections. If private household savings ($S$) stand at $\text{N}55\text{ billion}$, tax revenue ($T$) equals $\text{N}25\text{ billion}$, and private capital investment ($I$) is $\text{N}50\text{ billion}$, what level of government expenditure ($G$) is required to maintain circular flow equilibrium?
