Graphical Representation of the Aggregate Demand Function

Autonomous Demand

In a simplified economic model, total planned spending (aggregate demand, AD) is the sum of consumption (C) and planned investment (I). If the consumption function is given by the equation C = 250 + 0.6Y, where Y is income, and planned investment is fixed at a value of 150, which of the following equations correctly represents the aggregate demand function for this economy?

Analyzing Components of Aggregate Demand

Calculating Total Planned Spending

In a simplified economic model where total planned spending is the sum of consumption and a fixed amount of investment, the resulting aggregate demand (AD) function is given by the equation: $AD = c_0 + c_1Y + I$. Match each component from the equation to its correct economic description.

Comparing Economic Behavior via Aggregate Demand Functions

In a simplified economy, total planned spending (aggregate demand, AD) is the sum of consumption (C) and planned investment (I). The aggregate demand function is given by the equation AD = 500 + 0.75Y, where Y is income. If planned investment is a fixed amount of 200, which of the following equations correctly represents the consumption function for this economy?

Critique of the Simplified Aggregate Demand Model

In a simplified economy where total planned spending is the sum of consumption and planned investment, the consumption function is given by C = 100 + 0.8Y and planned investment (I) is a fixed amount of 50. If the current level of income (Y) is 1,000, the portion of total planned spending that is induced by income is ____.
