He also refers to his earlier researches (Chow 1989 and 2007, cited in Chow 2011) that also provide strong empirical evidence on the coherence of adaptive expectations with reality. Chow also conducts an econometric study in order to support his arguments, which shows the consistency of the model based on adaptive expectations with real data. Economic models and assumptions that they are based on should stay as simple as possible as long as they bring satisfactory results. The understanding and the role of expectations evolved over time.
