Keynesian Cross Model Concepts

The video builds on the Keynesian Cross model, focusing on planned aggregate expenditures. It explains the consumption function as a function of disposable income and simplifies the planned expenditure equation. The video discusses equilibrium in the economy, inventory effects, and how to shift equilibrium using government spending and other variables. The multiplier effect is introduced as a key concept in understanding changes in output.

What is the primary focus of the Keynesian Cross model?

• To evaluate the impact of interest rates on investment

• To study the effects of inflation on the economy

• To understand the equilibrium between aggregate output and expenditures

• To analyze the relationship between supply and demand

In the context of the consumption function, what does 'disposable income' refer to?

• Income excluding savings

• Income including government subsidies

• Income after taxes

• Total income before taxes

Which of the following is assumed to be constant in the planned expenditure formula?

• Net exports

• Consumption

• Government spending

• Aggregate income

What does the 45-degree line in the Keynesian Cross diagram represent?

• The point where output equals expenditures

• The point where supply equals demand

• The point where taxes equal government spending

• The point where investment equals savings

What happens when actual output exceeds planned expenditures?

• Inventories decrease

• Net exports decrease

• Inventories increase

• Government spending increases

Why is the slope of the planned expenditure line less than one?

• Because government spending is variable

• Because taxes are not considered

• Because people save a portion of their income

• Because people spend more than their income

What is the significance of the intersection point in the Keynesian Cross diagram?

• It marks the lowest level of government spending

• It represents the point of highest investment

• It shows the equilibrium level of output and expenditures

• It indicates the maximum level of output

How can the equilibrium in the Keynesian Cross model be shifted?

• By changing the slope of the 45-degree line

• By altering the constant terms in the expenditure formula

• By increasing aggregate income

• By decreasing taxes

What is the effect of increasing government spending on the planned expenditure curve?

• It changes the slope of the curve

• It has no effect on the curve

• It shifts the curve upward

• It shifts the curve downward

What is the multiplier effect in the context of the Keynesian Cross?

• The increase in aggregate income resulting from an increase in autonomous spending

• The decrease in taxes leading to higher consumption

• The impact of inflation on aggregate demand

• The effect of interest rates on investment
