Real Estate Transaction Taxes and Credit Supply
Michael Koetter, Philipp Marek, Antonios Mavropoulos
IWH Discussion Papers,
No. 26,
2022
Abstract
We exploit staggered real estate transaction tax (RETT) hikes across German states to identify the effect of house price changes on mortgage credit supply. Based on approximately 33 million real estate online listings, we construct a quarterly hedonic house price index (HPI) between 2008:q1 and 2017:q4, which we instrument with state-specific RETT changes to isolate the effect on mortgage credit supply by all local German banks. First, a RETT hike by one percentage point reduces HPI by 1.2%. This effect is driven by listings in rural regions. Second, a 1% contraction of HPI induced by an increase in the RETT leads to a 1.4% decline in mortgage lending. This transmission of fiscal policy to mortgage credit supply is effective across almost the entire bank capitalization distribution.

Channeling the Iron Ore Super-cycle: The Role of Regional Bank Branch Networks in Emerging Markets
Helge Littke
IWH Discussion Papers,
No. 11,
2018
Abstract
The role of the financial system to absorb and to intermediate commodity boom induced windfall gains efficiently presents one of the most pressing issues for developing economies. Using an exogenous increase in iron ore prices in March 2005, I analyse the role of regional bank branch networks in Brazil in reallocating capital from affected to non-affected regions. For the period from March 2004 to March 2006, I find that branches directly exposed to this shock by their geographical location experience an increase in deposit growth in the post-shock period relative to non-affected branches. Given that these deposits are not reinvested locally, I further show that branches located in the non-affected region increase lending growth depending on their indirect exposure to the booming regions via their branch network. Even tough, these results provide evidence against a Dutch Disease type crowding out of the non-iron ore sector, further evidence suggests that this capital reallocation is far from being optimal.

Climate Change and Corporate Innovation Processes
Wilfried Ehrenfeld
IWH Discussion Papers,
No. 13,
2012
Abstract
Das vorliegende Diskussionspapier stellt den inhaltlichen Rahmen der kumulativen Dissertation zum Thema „Climate Change and Corporate Innovation Processes“ an der Technischen Universität Dresden dar. Diese besteht aus sechs bereits veröffentlichten Fachartikeln. Durch die gegenwärtig öffentlich geführte Diskussion zum Thema Klimawandel stehen europäische Industrieunternehmen neuen Anforderungen gegenüber. Dazu zählen vor allem neue Ansprüche, die ihr betriebliches Umfeld an sie stellt. Eine Möglichkeit, auf diese neuen Ansprüche zu reagieren, ist Anpassung durch Innovation. Das übergeordnete Ziel der Dissertation ist es deshalb zu untersuchen, wie die Wahrnehmung des Klimawandels seitens der Anspruchsgruppen (Stakeholder) betriebliche Innovations-prozesse beeinflusst. In dem Zusammenhang werden diese Fragestellungen sowohl theoretisch als auch empirisch untersucht. Die Dissertation leistet so einen Beitrag zu verschiedenen Literaturströmungen auf dem Themengebiet „unternehmerische Anpassungsstrategien an den Klimawandel“.

Climate Innovation - The Case of the Central German Chemical Industry
Wilfried Ehrenfeld
IWH Discussion Papers,
No. 2,
2012
Abstract
In this article, we describe the results of a multiple case study on the indirect corporate innovation impact of climate change in the Central German chemical industry. We investigate the demands imposed on enterprises in this context as well as the sources, outcomes and determining factors in the innovative process at the corporate level. We argue that climate change drives corporate innovations through various channels. A main finding is that rising energy prices were a key driver for incremental energy efficiency innovations in the enterprises’ production processes. For product innovation, customer requests were a main driver, though often these requests are not directly related to climate issues. The introduction or extension of environmental and energy management systems as well as the certification of these are the most common forms of organizational innovations. For marketing purposes, the topic of climate change was hardly utilized so far. As the most important determinants for corporate climate innovations, corporate structure and flexibility of the product portfolio, political asymmetry regarding environmental regulation and governmental funding were identified.

Currency Crises and the Stock Market: Empirical Evidence for Another Type of Twin Crisis
Stefan Eichler, Dominik Maltritz
Applied Economics,
No. 29,
2011
Abstract
We explore the dependency between currency crises and the stock market in emerging economies. Our focus is two-fold. First, the risk of a currency crisis rises as the foreign stake in the domestic stock market increases. Successful economies with high capital flows into their booming stock markets especially are prone to stock market-induced currency crises. Second, we apply the dividend growth model to show that stock markets crash in the run-up to a currency crisis. This new type of twin crisis is empirically tested by employing a logit framework using quarterly data for 33 emerging economies for 1994Q1–2007Q4.
