Modeling Inflation Dynamics: A Critical Review of Recent Research

In recent years, a broad academic consensus has arisen that favors using rational expectations sticky‐price models to capture inflation dynamics. We review the principal conclusions of this literature concerning: (1) the ability of these models to fit the data; (2) the importance of rational forward‐looking expectations in price setting; and (3) the appropriate measure of inflationary pressures. We argue that existing models fail to provide a useful empirical description of the inflation process.
