Economics 11 Q1 - AD

What does aggregate demand (AD) represent?

• Total supply of goods and services in an economy

• Total demand for all goods and services in an economy at a given price level

• The total consumption expenditure in an economy

• The demand for imports in an economy

Answer explanation

Explanation: Aggregate demand represents the total quantity of goods and services demanded in an economy at various price levels, encompassing consumption, investment, government spending, and net exports.

Which of the following is a component of aggregate demand?

• Investment

• Technology

• Labor

• Capital

Answer explanation

Explanation: Aggregate demand consists of four components: consumption (C), investment (I), government spending (G), and net exports (X - M).

Which of the following will most likely increase consumption (C) in aggregate demand?

• An increase in income tax

• A rise in interest rates

• A decrease in disposable income

• An increase in consumer confidence

Answer explanation

Explanation: An increase in consumer confidence leads people to spend more, boosting consumption, one of the key components of aggregate demand.

Which of the following would cause a rightward shift in the AD curve?

• A decrease in government spending

• A decrease in investment

• An increase in exports

• A decrease in consumer confidence

Answer explanation

Explanation: A rightward shift in the AD curve occurs when there’s an increase in any component of AD, such as a rise in exports, which increases overall demand for a country’s goods and services.

An increase in investment (I) would most likely be caused by:

• Higher interest rates

• An increase in business taxes

• An increase in expected returns on investment

• A decrease in consumer demand

Answer explanation

Explanation: When firms expect higher future profits, they are more likely to invest more, leading to an increase in investment, a key driver of aggregate demand.

What happens to aggregate demand when net exports (X - M) decrease?

• Aggregate demand increases

• Aggregate demand decreases

• Aggregate demand remains unchanged

• Aggregate demand fluctuates unpredictably

Answer explanation

Explanation: If net exports decrease (i.e., imports exceed exports), there is less demand for a country’s goods and services, leading to a fall in aggregate demand.

If the government increases spending on infrastructure projects, the likely effect on aggregate demand will be:

• A decrease in AD

• No change in AD

• An increase in AD

• A leftward shift in the AD curve

Answer explanation

Explanation: Government spending is a direct component of aggregate demand, so an increase in infrastructure projects increases aggregate demand.

A decrease in aggregate demand is most likely caused by:

• An increase in net exports

• A decrease in consumer spending

• A decrease in interest rates

• An increase in government spending

Answer explanation

Explanation: A drop in consumer spending directly reduces aggregate demand since consumption is a large part of AD.

Which of the following would cause a leftward shift in the AD curve?

• A decrease in taxes

• An increase in government subsidies

• A decrease in investment

• An increase in net exports

Answer explanation

Explanation: A reduction in investment leads to a decrease in aggregate demand, causing a leftward shift in the AD curve.

What impact does a reduction in imports (M) have on aggregate demand?

• Increases AD

• Decreases AD

• No impact on AD

• Shifts AD left

Answer explanation

Explanation: A decrease in imports implies that consumers are purchasing more domestically produced goods, which increases aggregate demand (since net exports, X - M, rise).
