    Deflationary vs. inflationary expectations : a new-Keynesian perspective with heterogeneous agents and monetary believes
    (2009) Sauter, Oliver; Geiger, Felix
    We expand a standard New-Keynesian model by allowing for a special role of money in the inflation and expectations building process. Motivated by the two-pillar Phillips curve, we introduce heterogeneous expectations. Thereby a fraction of agents forms inflation expectations by observing trend money growth. We show that in the presence of these monetary believers, contractive shocks to the economy produce smoother dynamics for inflation and output. We also find that monetary policy should follow a conventional Taylor rule with contemporaneous inflation and output data, if it is uncertain about the fraction of monetary believers.

    Price stability versus full employment : the Phillips curve dilemma reconsidered
    (2016) Schwarzer, Johannes A.; Hagemann, Harald
    This dissertation focuses on different interpretations of the Phillips curve particularly from the end of the 1950s to the beginning of the 1970s. In the 1950s and 1960s the Phillips curve was mainly perceived as a “cruel dilemma”. From this perspective the curve seemed to imply that price stability and full employment (and to some extent also economic growth) are mutually conflicting policy objectives. Furthermore, the curve was usually regarded as describing disequilibrium phenomena, that is, excess demand or supply on the labour market causing a price reaction. On the other hand, particularly since the late 1960s, the Phillips curve became more and more embedded into an equilibrium approach, so that departures from a “natural rate of unemployment” are possible only by surprise inflation. Moreover, within this view, price stability and full employment are assumed to be compatible policy goals. These two different lines of thought are presented in three already published peer-reviewed journal articles which are reproduced in the first half of this Ph.D. thesis. The underlying reasons for these different views are then discussed in the remainder of the dissertation. It is shown that both lines of thought built on very different assumptions regarding the causes of inflation and the specific kind of unemployment prevailing in the economy. The discussion is then related to current economic models (such as the New Keynesian approach) which also point at a possible conflict between price stability and full employment.
