Research Objectives and Key Topics

The primary aim of this thesis is to critically evaluate whether the current price development in the German real estate market exhibits characteristics of a speculative bubble. By applying Robert J. Shiller's concept of "irrational exuberance" and utilizing the Case Shiller home price index (CS HPI) as an analytical indicator, the research investigates whether findings from the US market regarding speculative dynamics can be meaningfully transferred to the German context, while accounting for structural market differences.

• Structural characteristics and financing mechanisms of the German real estate market.
• Deep analysis of the concept of "irrational exuberance" and its psychological drivers in financial markets.
• Methodological discussion and historical context of the Case Shiller home price index.
• Application of international real estate bubble indicators to identify potential market overheating in Germany.
• Evaluation of the role of interest rates and media influence on investor sentiment and asset valuations.

Frequently Asked Questions

What is the core subject of this thesis?

This thesis examines the risk of speculative housing price bubbles in the German real estate market, utilizing Robert J. Shiller’s framework of "irrational exuberance" to analyze current trends.

The work covers structural market analysis, the psychological foundations of financial speculation, the history and utility of the Case Shiller home price index, and the impact of macroeconomic factors like monetary policy on property prices.

What is the main research objective?

The goal is to determine if the German residential real estate market exhibits bubble-like characteristics by assessing its price development against concepts of "irrational exuberance" and established valuation indices.

Which scientific methodology is applied?

The thesis utilizes a literature-based conceptual analysis, combining economic data from the German market with Shiller’s theoretical and qualitative frameworks on speculative market behaviors.

What topics are discussed in the main chapters?

The chapters address market structure, the psychological drivers and amplifiers of speculative bubbles (such as media influence and herd behavior), the mechanics of price indices, and the specific application of these theories to the German metropolitan landscape.

Which keywords best describe this research?

The research is best characterized by terms such as irrational exuberance, real estate market, behavioural finance, asset bubble, and market efficiency.

How does the author evaluate the transferability of the US-developed index to Germany?
