In economics, adaptive expectations is a hypothesized process by which people form their expectations about what will happen in the future based on what has happened in the past. For example, if people want to create an expectation of the inflation rate in the future, they can refer to past inflation rates to infer some consistencies and could ...

Jan 1, 2017 · The adaptive expectations hypothesis may be stated most succinctly in the form of the equation: $$ {E}_t {x}_ {t+1}=\sum_ {i=0}^ {\infty}\lambda {\left (1-\lambda \right)}^i {x}_ {t- i;} 0<\lambda <1 $$. where E denotes an expectation, x is the variable whose expectation is being calculated and t indexes time.
Adaptive expectations played a prominent role in macroeconomics in the 1960s and 1970s. For example, inflation expectations were often modeled adaptively in the analysis of the expectations augmented Phillips curve. View chapter Explore book.
