Adaptive expectations & Rational expectations

Question:

Compare and contrast 'adaptive expectations' (Hubbard uses adaptive expectations)  and 'rational expectations' in modeling expectations.

Answer:

Adaptive expectations theory assumes that people expect the inflation rate next year to be equal to the inflation rate last year. The rational expectation hypothesis, on the other hand, assumes that economic agents use all the available information to make an expectation about the next year's inflation rate. So the rational expectation approach make the inflation expectation to be more information based and not merely by observing the last year's inflation and expect it to persist next year.
