Expectation and Anticipation

"[Expectation] refers to a state of mind, whereas the latter [anticipation] refers to actual behaviour. To expect something means simply to believe with greater or less confidence that it will occur, whereas to anticipate something means both to expect it and to act upon this expectation. ... To redistribute income, inflation must therefore be unanticipated." R.E. Rowthorn (1977, p.215).
