The German Residential Real Estate Market and the Presence of a Bubble Buchkatalog

Masterarbeit aus dem Jahr 2022 im Fachbereich VWL - Sonstiges, Note: 1, 7, Fachhochschule Kufstein Tirol (International Business Studies), Sprache: Deutsch, Abstract: The starting point for this thesis and the associated question were price developments observable on the residential property market as well as increased media reporting. Against this background, the following question was examined with scientific methods within the framework of this work: Is a bubble formation recognisable on the German real estate market and what regional differences can be identified in answering this question? As a first step, price-influencing factors were examined in more detail and the price development relative to annual rent ratio, income and construction costs was examined. In order to be able to identify price bubbles on the residential property market in a measurable and comprehensible way, the price development was analysed in a second step with the mathematical procedure according to Diba and Grossmann, which uses the Augmented Dickey Fuller Test. The procedure is based on the premise that the price of a good is related to its fundamental value. To examine the price development in the residential property market, the fundamental value used for comparison purposes is derived from the development of the rent price index, the index of average gross monthly earnings and the construction cost index. The house price index was used as a price indicator for residential property. With the help of the Augmented-Dickey-Fuller Test, the development of the various indices was examined and compared with regard to their degree of stationarity. This investigation was carried out for the overall German residential real estate market in the observation period 2010-2021 in order to obtain an up-to-date picture.
