Topic 6 Part 1 Flashcards
What is a business cycle?
The repeated sequence of economic expansion giving way to temporary decline followed by recovery
What are economists concerned with in terms of business cycles? (2)
(1) what causes business cycles and
(2) how policymakers should respond to them
Where did business cycle research start?
National Bureau of Economic Research (NBER)
Are business cycles recurrent or periodic?
Recurrent
What is the book that outlines perfectly how business cycles work?
Measuring Business Cycles by A. Burns and W. Mitchell (1946)
What are the 5 main points that Burns and Mitchell touch upon in their book?
✓Aggregate economic activity
✓Expansions and contractions
✓Comovement
✓The business cycle is recurrent, but not periodic
✓The business cycle is persistent
What did Burns and Mitchell say about aggregate economic activity? (2)
Real GDP measures most closely aggregate economic activity.
However, it is important to look at other indicators of activity such as employment and financial market variables.
What did Burns and Mitchell say about expansions and contractions?
Aggregate economic activity declines in a contraction or recession until it reaches a trough.
After a trough, activity increases in an expansion or boom until it reaches a peak.
The sequence from one peak to the next, or from one trough to the next, is a business cycle.
What is a severe depression called?
A depression
What does comovement mean?
The correlated or similar movement of two or more entities.
The tendency of many economic variables to move together in a predictable way over the
business cycle is called comovement
What do Burns and Mitchell say about comovement?
Business cycles do not occur in just a few sectors or in just a few economic variables.
Instead, expansions and contractions occur at about the same time in many economic activities.
What do Burns and Mitchell mean when they say the business cycle is recurrent, but not periodic?
Recurrent means the pattern of contraction–trough–expansion–peak occurs again and again.
Not being periodic means that it doesn’t occur at regular, predictable intervals.
What do Burns and Mitchell mean when they say the business cycle is persistent?
The duration of a complete business cycle can vary greatly from a year to more than a decade and predicting it is difficult.
However, declines are followed by further declines; growth is followed by more growth
What does procyclical mean?
An economic variable that moves in the same direction as aggregate economic activity.
What does countercylical mean?
A variable that moves in the opposite direction to aggregate economic activity.
What does acyclical mean?
Variables that do not display a clear pattern over the business cycle.
