How much does quality adjustment matter in measuring consumer price inflation? To address this question, we use different sources of micro and macro price data for Germany and the euro area. For Germany, we find that quality adjustment applies to a large range of goods and services but, on...

Using CPI micro data for 11 euro area countries covering about 60% of the euro area consumption basket over the period 2010-2019, we document new findings on consumer price rigidity in the euro area: (i) each month on average 12.3% of prices change, which compares with 19.3% in the United...

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...

We study how millions of highly granular and weekly household scanner data combined with novel machine learning techniques can help to improve the nowcast of monthly German inflation in real time. Our nowcasting exercise targets three hierarchy levels of the official consumer price index. First,...

We use a simple macroeconomic model proposed by Bernanke and Blanchard (2023) to investigate the reasons for the recent sharp rise in inflation. Applied to Germany and the euro area, the model suggests that the surge in inflation has mainly been caused by commodity price shocks and supply...

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...

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...

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...

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...
