Real Estate Transaction Taxes and Credit Supply
Michael Koetter, Philipp Marek, Antonios Mavropoulos
IWH Discussion Papers,
Nr. 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.

Kommentar: Immobilienbesitz in Inflationszeiten: Ein Damoklesschwert über der Finanzstabilität?
Michael Koetter
Wirtschaft im Wandel,
Nr. 3,
2022
Abstract
Zu Beginn meines Studiums bot sich mir überall das gleiche Schauspiel: lange Warteschlangen anderer „Frischlinge“ vor dem neu renovierten WG-Zimmer samt modernstem 56k-Modem, fußläufig zu Uni und Lieblings-Café gelegen, mit happiger Miete zwar, aber irgendwie noch im finanziellen Lösungsraum. Eifrig bereitete ich tolle Argumente vor, warum gerade ich der optimale WG-Zuwachs sei, bevor ich mich einreihte. Schade, dass es dann meist jemand anderes wurde, aber nur kein Neid! Schade aber auch, dass die Suche nach einem Dach über dem Kopf für viele Menschen auch später frustrierend bleibt. Ein bezahlbares Zuhause zu suchen bleibt vielerorts ein von der Spaßsteuer befreites Unterfangen, ob nun für Berufseinsteiger oder die vierköpfige Familie, ob nun in Leipzig oder Köln.

Explaining Regional Disparities in Housing Prices Across German Districts
Lars Brausewetter, Stephan L. Thomsen, Johannes Trunzer
IWH Discussion Papers,
Nr. 13,
2022
Abstract
Over the last decade, German housing prices have increased unprecedentedly. Drawing on quality-adjusted housing price data at the district level, we document large and increasing regional disparities: Growth rates were higher in 1) the largest seven cities, 2) districts located in the south, and 3) districts with higher initial price levels. Indications of price bubbles are concentrated in the largest cities and in the purchasing market. Prices seem to be driven by the demand side: Increasing population density, higher shares of academically educated employees and increasing purchasing power explain our findings, while supply remained relatively constrained in the short term.

Political Cycles in Bank Lending to the Government
Michael Koetter, Alexander Popov
Review of Financial Studies,
Nr. 6,
2021
Abstract
We study how political party turnover after German state elections affects banks’ lending to the regional government. We find that between 1992 and 2018, party turnover at the state level leads to a sharp and substantial increase in lending by local savings banks to their home-state government. This effect is accompanied by an equivalent reduction in private lending. A statistical association between political party turnover and government lending is absent for comparable cooperative banks that exhibit a similar regional organization and business model. Our results suggest that political frictions may interfere with government-owned banks’ local development objectives.

To Rent or not to Rent: A Household Finance Perspective on Berlin's Short-term Rental Regulation
Antonios Mavropoulos
IWH Discussion Papers,
Nr. 1,
2021
Abstract
With the increasing concerns that accompany the rising trends of house sharing economies, regulators impose new laws to counteract housing supply scarcity. In this paper, I investigate whether the ban on short-term entire house listings activated in Berlin in May 2016 had any adverse effects from a household finance perspective. More specifically, I derive short-term rental income and counter-factually compare it with long-term rental income to find that the ban, by decreasing the supply of short-term housing, accelerated short-term rental income but did not have any direct effect on long-term rental income. Commercial home-owners therefore would find renting on the short-term market to be financially advantageous.
