Real estate investment dynamics

Investitionsdynamik im Immobiliensektor
Authors: Gruber, Johannes;

Real estate investment dynamics

Abstract

Ausgangspunkt dieser Dissertation ist das steigende Interesse an der Beziehung zwischen dem Immobiliensektor und der Gesamtwirtschaft, wobei der Fokus auf die Dynamik der allgemeinen Investitionstätigkeit gerichtet wird. Seit der durch das Platzen der U.S.-amerikanischen Immobilienblase 2006 ausgelösten „Subprime Krise“ einschließlich des darauf folgenden Beinahe-Kollapses des US-Finanzsystems wird der Dynamik von Investitionen im Immobiliensektor besonderes Augenmerk geschenkt. Um die Entwicklung von Immobilieninvestitionen und deren Beziehung zur Gesamtökonomie zu untersuchen, wird im ersten Teil meiner Dissertation ein dynamisches stochastisches generelles Gleichgewichtsmodell mit einem Geschäfts- und einem Immobiliensektor vorgestellt. Der Immobiliensektor zeichnet sich durch eine Investitionsrestriktion in Form einer Errichtungsphase für Gebäude aus. Anhand von U.S. Quartalsdaten für den Zeitraum 1970 - 2007 wird überprüft, ob das Modell verschiedene stilisierte Fakten des U.S.- amerikanischen Immobilienmarktes und der U.S. Wirtschaft allgemein nachbilden kann. Ein anderes viel diskutiertes Thema im Zusammenhang mit der "Subprime Krise" ist die Beziehung von Bankkrediten, Immobilienpreisen und der Gesamtökonomie. Im zweiten Teil meiner Dissertation gehe ich daher der Frage nach, welche Effekte makroökonomische Schocks und Veränderungen in der Kreditvergabepolitik auf den deutschen Immobiliensektor haben. Mittels einer strukturellen Vektorautoregression (SVAR) wird der dynamische Zusammenhang zwischen den Preisen von Geschäftsimmobilen, Krediten an die Bauindustrie, Bauinvestitionen und dem gesamtwirtschaftlichen Output analysiert. Die SVAR Schätzungen werden mit aggregierte Daten für Gesamt-Deutschland und für die Länder Bayern und Nordrhein-Westfalen im Zeitraum 1975 - 2004 durchgeführt.

This thesis is motivated by the steadily increasing interest in the dynamic relationship between the macro-economy and the real estate sector. One of the main issues in this respect is to study the investment dynamics. Since the bursting of the U.S. housing bubble in 2006 is identified as the point of origin of the so called subprime crises, which led to the collapse of the U.S. financial system, the dynamics of real estate investments is of particular interest. In the first part of my thesis I investigate the dynamics of residential investment and its relationship to the overall economy by the means of a dynamic stochastic general equilibrium (DSGE) model in which a consumption good sector and a housing sector are incorporated. Residential investment is characterized in this model by a time-to-build restriction. The model is brought to U.S. quarterly data - in the period 1970 - 2007 - in order to evaluate whether it can account for stylized facts of the U.S. housing economy as well as the U.S. Macro - economy. Another much talked real estate topic with respect to the subprime crisis is the relationship between bank lending, property prices and economic activity. To that end, the second part of my thesis examines the potential effects of macro-policy and bank lending shocks on the German real estate sector. In particular, the importance of macroeconomic factors like credit to real estate construction, residential investment, and gross domestic product for the dynamics of German commercial real estate prices are analyzed by the means of a structural Vector-Autoregression (SVAR). The SVAR estimation is conduct for both, aggregate Germany and the largest regional states of Bavaria and Nordrhein-Westfalen for the period 1975 to 2004.
