Central bankers rely on the inflation-expectation hypothesis, which says that “expected inflation is a key determinant of actual inflation.” The proposition is intuitive, and it is convenient in explaining variations in other models, such as the Phillips curve, which describes the inverse correlation between unemployment and inflation rates.
