Consumption theory has always been a neglected field in Post Keynesian economics, whereas it is at the center of New Keynesian economics. This paper investigates similarities and differences between the two approaches. I will show that the newer mainstream models indeed give results that are...

The contribution of this paper is twofold. First, a thorough presentation of the state of the art of the New Keynesian Macroeconomic model is provided. A discussion of its empirical caveats follows and some recent extensions of the standard model are evaluated in more detail. Second, a key...

Building on the hypotheses of loss aversion with respect to price increases and availability of frequently bought goods, Brachinger (2006, 2008) constructs an alternative index of perceived inflation (IPI), which can reproduce the jump in the measure for perceived inflation after the Euro...

Building on Prospect Theory, we apply the concept of loss aversion to the formation of inflation perceptions and test empirically for non-linearities in the inflation-perceptions relation for a panel of 10 Euro area countries. Specifically, under the assumption of loss aversion, inflation...

This paper aims at providing macroeconomists with a detailed exposition of the New Keynesian DSGE model. Both the sticky price version and the sticky information variant are derived mathematically. Moreover, we simulate the models, also including lagged terms in the sticky price version, and...

Based on annual data for growth and inflation forecasts for Germany covering the time span from 1970 to 2007 and up to 17 different forecasts per year, we test for a possible asymmetry of the forecasters' loss function and estimate the degree of asymmetry for each forecasting institution using...
