Understanding Expectations in Economics Flashcards
(68 cards)
What does the adaptive expectations hypothesis suggest?
Individuals form their expectations of future inflation based on past trends.
How do individuals expect future inflation if it has been consistently high?
They expect it to remain high.
How do individuals expect future inflation if it has been low?
They anticipate it will stay low.
What type of approach does the adaptive expectations hypothesis represent?
A backward-looking approach.
What economic concept was widely used before the development of rational expectations?
Adaptive expectations.
What significant economic event in the 1970s is associated with the breakdown of the Phillips Curve?
Stagflation.
What policy mistake did governments make during the 1970s regarding inflation and unemployment?
They believed that increasing inflation could reduce unemployment.
What was the consequence of workers and firms adapting their expectations to persistently high inflation?
They demanded higher wages, leading to a wage-price spiral.
What is a wage-price spiral?
A situation where rising wages lead to higher prices, which in turn leads to further wage demands.
Fill in the blank: The adaptive expectations hypothesis was used before the development of _______.
[rational expectations].
True or False: The adaptive expectations hypothesis is a forward-looking approach to inflation.
False.
What is a strength of Adaptive Expectations?
Simplicity → Useful for explaining short-term behavior.
Adaptive Expectations provide a straightforward framework for understanding immediate responses in economic behavior.
What is a limitation of Adaptive Expectations in volatile economies?
Fails in volatile economies → Does not account for sudden shifts in economic policy or external shocks.
This limitation indicates that Adaptive Expectations may not accurately predict behavior during times of economic instability.
In what type of environments is Adaptive Expectations considered empirically weak?
Empirically weak in high-information environments → Agents do not always rely on past trends when they have access to better data.
High-information environments allow agents to make more informed decisions, reducing reliance on historical data.
What is the rational expectations hypothesis?
Individuals use all available information to make optimal predictions about the future.
Developed by Robert Lucas and John Muth.
According to the rational expectations hypothesis, how are expectations generally formed?
On average, expectations are correct, though individual errors may occur.
Who was the Chair of the Federal Reserve during the 1980s Volcker Shock?
Paul Volcker.
What action did Paul Volcker take to combat high inflation in the early 1980s?
Aggressively raised interest rates.
What was a consequence of the aggressive interest rate hikes during the 1981-1982 period?
A severe recession.
What occurred once economic agents were convinced that the Fed was committed to reducing inflation?
Expectations adjusted, and inflation fell sharply.
Fill in the blank: The rational expectations hypothesis suggests that economic agents use _______ to make predictions.
[all available information].
True or False: The rational expectations hypothesis states that individual expectations are always correct.
False.
What does the example of the 1980s Volcker Shock illustrate about rational expectations?
Rational expectations can make disinflation faster and less costly than previously believed.
What is the main theoretical implication of rational expectations?
Explains why anticipated policies often have limited effects
For example, monetary policy is less effective if it is expected.
