Over the last three decades the supply of economic statistics has vastly improved. Unfortunately, statistics on regional price levels (sub-national purchasing power parities) have been exempt from this positive trend, even though they are indispensable for meaningful spatial comparisons of...

The present paper shows that product-specific regional price dispersion usually causes the Country-Product-Dummy (CPD) method to be biased. In cases where it is not, this index number method is still inefficient and inference is invalid. In view of this, a nonlinear generalization of the CPD...

We show that exchange rate pass-through to consumer prices varies not only across countries, but also over time. Previous literature has highlighted the role of an economy's "structure" - such as its inflation volatility, inflation rate, use of foreign currency invoicing, and openness - in...

Spatial price comparisons rely to a high degree on the quality of the underlying price data that are collected within or across countries. Below the basic heading level, these price data often exhibit large gaps. Therefore, stochastic index number methods like the CPDmethod and the GEKS method...

This paper analyses the effects of the creation or removal of borders on firms' profits and their optimal location in an autarkic region. A firm chooses a position close to a border if a crucial degree of openness is achieved. Furthermore, the positive effect of removal of borders decreases in...

Our research, based on the ZEW-Foundation Panel East, examines whether high-tech start-ups are mainly founded in scientific and infrastructural well suited regions or not. Estimation results on the level of postcode areas confirm the hypothesis that specific human capital, knowledge spillovers...

In the paper we analyze the convergence process of the West German Laender from 1970 to 1995 using descriptive tools as well as panel estimation methods. Although there have been some winners in this process, the main finding is that convergence was insufficient in the sense that no gains have...

This paper is devoted to a new estimation of the non-accelerating inflation rate of unemployment (NAIRU) for the West German Economy 1980 to 1998. The novelty of the paper is the estimation of a time-varying NAIRU for West Germany employing the Kalman method together with confidence intervals...

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,...

Using detailed establishment-level micro data, this paper analyzes for the German case the hypothesis by Aghion, Bergeaud, Boppart, Klenow, and Li (2019), stating that officially published figures for real output growth would be systematically understated. The effect rests on overstated...
