All Questions (12)

According to the provided text, what are the primary drivers of the fluctuations in aggregate output and employment known as business cycles?

A) Changes in the natural rate of unemployment

B) The difference between actual and potential output

C) Changes in aggregate supply and/or aggregate demand

D) The regular occurrence of peaks and troughs

Correct Answer: C

The content explicitly states that 'Business cycles are fluctuations in aggregate output and employment because of changes in aggregate supply and/or aggregate demand.'

Which of the following pairs correctly identifies the two main phases of a business cycle?

A) Peak and Trough

B) Recession and Expansion

C) Output Gap and Potential Output

D) Aggregate Supply and Aggregate Demand

Correct Answer: B

The provided text directly states: 'The phases of a business cycle are recession and expansion.'

The points in a business cycle where the economy changes direction from expansion to recession or vice versa are known as what?

A) Phases

B) Output gaps

C) Full-employment points

D) Turning points

Correct Answer: D

The content identifies 'peak and trough' as the 'turning points of a business cycle.' These are the points where the economy's direction changes.

What is the term for the level of GDP where the unemployment rate is equal to the natural rate of unemployment?

A) Actual output

B) Peak output

C) Potential output

D) Trough output

Correct Answer: C

The content defines potential output as 'the level of GDP where unemployment is equal to the natural rate of unemployment.' It is also called full-employment output.

The 'output gap' is defined as the difference between which two economic measures?

A) The peak and the trough of a business cycle

B) Aggregate demand and aggregate supply

C) The current unemployment rate and the natural rate of unemployment

D) Actual output and potential output

Correct Answer: D

The text provides a direct definition: 'The difference between actual output and potential output is the output gap.'

An economy has just experienced the turning point known as a 'peak'. Which phase of the business cycle will immediately follow?

A) Expansion

B) Trough

C) Recession

D) Full employment

Correct Answer: C

A peak is the turning point that marks the end of an expansion and the beginning of a recession, which is a period of declining aggregate output.

After a prolonged period of economic decline, an economy reaches a 'trough'. What is the subsequent phase in the business cycle?

A) A second recession

B) A peak

C) Expansion

D) A larger output gap

Correct Answer: C

A trough is the turning point at the bottom of a recession. It is followed by a period of rising aggregate output, which is defined as the expansion phase.

During a recession, what is the most likely relationship between actual output and potential output?

A) Actual output is greater than potential output.

B) Actual output is less than potential output.

C) Actual output is equal to potential output.

D) Potential output decreases to match actual output.

Correct Answer: B

A recession is a phase of declining aggregate output. During this time, the economy is producing below its full-employment capability, meaning actual output is less than potential output, resulting in a negative output gap.

According to the provided text, 'full-employment output' is another name for which concept?

A) The output gap

B) Peak output

C) Actual output

D) Potential output

Correct Answer: D

The content explicitly states: 'Potential output is also called full-employment output.'

If an economy's actual output is currently higher than its full-employment output, which of the following must be true?

A) The economy is in a recession.

B) The unemployment rate is higher than the natural rate of unemployment.

C) The economy is in an expansionary phase.

D) The output gap is negative.

Correct Answer: C

When actual output exceeds full-employment (potential) output, the economy is producing at an unsustainable level. This occurs during a strong expansion, often leading up to a peak. This situation corresponds to a positive output gap and an unemployment rate below the natural rate.

On a graph illustrating the business cycle, the turning point that represents the end of an expansion is called the:

A) Trough

B) Recession

C) Peak

D) Output gap

Correct Answer: C

The peak is defined as the highest turning point of a business cycle, marking the end of the expansion phase and the beginning of a recession.

Which of the following is true when an economy's output gap is zero?

A) The economy is at the peak of the business cycle.

B) The unemployment rate is equal to the natural rate of unemployment.

C) The economy is experiencing a recession.

D) Aggregate demand has permanently stopped fluctuating.

Correct Answer: B

An output gap of zero means that actual output is equal to potential output. By definition, potential output (or full-employment output) is the level of GDP where the unemployment rate is equal to the natural rate of unemployment.
