European Real Estate Prices

Michael Koetter, Felix Noth
IWH Technical Reports, No. 3, 2022
Abstract

Real estate markets are pivotal to financial stability given their dual role as the underlying asset of crucial financial products in financial systems, such as mortgage loans and asset-backed securities, and the primary source of household wealth alike. As such, they also play traditionally a crucial role for the transmission of monetary policy. Imbalances and sudden corrections in real estate markets have been the root cause of many financial crises over the last decades. But whereas some national, often survey-based indicators of real estate prices are provided by central banks and statistical offices, a comprehensive collection of purchase prices, rents, and proxies for the liquidity of European real estate markets is lacking. The IWH European Real Estate Index (EREI) seeks to fill this void for residential property. This technical report describes the gathering and processing of sale and rental prices for properties in 18 European countries. We provide the general scrapeing step in the section before describing country-specific details for each country in separated sub-sections.

IWH-Tarif-Check: Trotz kräftig steigender Tariflöhne in der Metall- und Elektroindustrie realer Netto-Lohnverlust im Jahr 2023

Oliver Holtemöller, Birgit Schultz
IWH-Tarif-Check, No. 1, 2022
Abstract
Nach mehrjähriger pandemiebedingter Pause wieder reguläre Tariflohnerhöhungen für die Beschäftigten in der Metall- und Elektroindustrie Die Tarifvertragsparteien in der Metall- und Elektroindustrie haben sich erstmalig seit der Corona-Pandemie auf eine Stufenerhöhung der Tariflöhne in Höhe von 5,2% ab Juni 2023 und von 3,3% ab Mai 2024 geeinigt. Zusätzlich wurden zwei lohnsteuer- und sozialversicherungsabgabenfreie Inflationsausgleichsprämien von jeweils 1 500 Euro vereinbart, die zu Beginn des Jahres 2023 und 2024 gezahlt werden. Der Tarifvertrag läuft bis Ende September 2024. Auch gibt es ab dem Jahr 2023 einen Anstieg des bereits früher vereinbarten jährlich gezahlten Zusatzentgelts.

Automation with Heterogeneous Agents: The Effect on Consumption Inequality

Tommaso Santini
IWH Discussion Papers, No. 28, 2022
Abstract
In this paper, I study technological change as a candidate for the observed increase in consumption inequality in the United States. I build an incomplete market model with educational choice combined with a task-based model on the production side. I consider two channels through which technology affects inequality: the skill that an agent can supply in the labor market and the level of capital she owns. In a quantitative analysis, I show that (i) the model replicates the increase in consumption inequality between 1981 and 2008 in the US (ii) educational choice and the return to wealth are quantitatively important in explaining the increase in consumption inequality.

Where to Go? High-skilled Individuals’ Regional Preferences

Sabrina Jeworrek, Matthias Brachert
IWH Discussion Papers, No. 27, 2022
Abstract
We conduct a discrete choice experiment to investigate how the location of a firm in a rural or urban region affects job attractiveness and contributes to the spatial sorting of university students and graduates. We characterize the attractiveness of a location based on several dimensions (social life, public infrastructure, connectivity) and combine this information with an urban or rural attribution. We also vary job design as well as contractual characteristics of the job. We find that job offers from companies in rural areas are generally considered less attractive. This is true regardless of the attractiveness of the region. The negative perception is particularly pronounced among persons with urban origin and singles. These persons rate job offers from rural regions significantly worse. In contrast, high-skilled individuals who originate from rural areas as well as individuals with partners and kids have no specific preference for jobs in urban or rural areas.

IWH-Flash-Indikator IV. Quartal 2022 und I. Quartal 2023

Katja Heinisch, Oliver Holtemöller, Axel Lindner, Birgit Schultz
IWH-Flash-Indikator, No. 4, 2022
Abstract
Im dritten Quartal 2022 konnte die Wirtschaftsleistung in Deutschland mit 0,3% nochmals zulegen. Vor allem die privaten Haushalte waren in Sommerlaune und konsumierten großzügig; die Erholung von der Pandemie dominierte bislang die negativen Folgen der hohen Energiepreise. Jedoch dürften ab Herbst die weiter ansteigenden Verbraucherpreise und die Energieprobleme die Kauflaune der privaten Haushalte deutlich dämpfen. Zudem werden energieintensive Unternehmen des Verarbeitenden Gewerbes wegen der gestiegenen Gas- und Strompreise ihre Produktion wohl weiter einschränken. Die Lieferkettenprobleme sind zwar etwas zurückgegangen, sie sind aber nicht zuletzt aufgrund der restriktiven COVID-Maßnahmen in China nach wie vor vorhanden. Ein Ende des Krieges in der Ukraine ist nicht in Sicht. Auch deshalb gehen die Auftragseingänge weiter deutlich zurück. Dies alles dürfte dazu führen, dass das Bruttoinlandsprodukt im vierten Quartal 2022 und im ersten Quartal 2023 schrumpft und Deutschland damit in eine Rezession rutscht. Insgesamt wird die Wirtschaftsleistung laut IWH-Flash-Indikator im vierten Quartal 2022 um 0,6% und zu Beginn des nächsten Jahres um 0,3% zurückgehen (vgl. Abbildung 1).

Environmental Reputational Risk, Negative Media Attention and Financial Performance

Leonardo Becchetti, Rocco Ciciretti, Iftekhar Hasan, Gabriele La Licata
Financial Markets, Institutions and Instruments, No. 4, 2022
Abstract
Tracing negative media attention, this paper investigates the effect of reputational risk on firm value. Decomposing reputational damage into environmental, social and corporate-governance dimensions, it reports that environmental reputational risk has the most significant negative effect on price earnings, i.e., firms exposed to environmental risk are likely to be priced at a discount or charged a higher risk premium when discounting future earnings.

Real Estate Transaction Taxes and Credit Supply

Michael Koetter, Philipp Marek, Antonios Mavropoulos
IWH Discussion Papers, No. 26, 2022
published in: Journal of Financial Stability
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.

Bitcoin Flash Crash on May 19, 2021: What Did Really Happen on Binance?

Tim Baumgartner, Andre Guettler
IWH Discussion Papers, No. 25, 2022
Abstract
Bitcoin plunged by 30% on May 19, 2021. We examine the outage the largest crypto exchange Binance experienced during the crash, when it halted trading for retail clients and stopped providing transaction data. We find evidence that Binance back-filled these missing transactions with data that does not conform to Benford‘s Law. The Bitcoin futures price difference between Binance and other exchanges was seven times larger during the crash period compared to a prior reference period. Data manipulation is a plausible explanation for our findings. These actions are in line with Binance aiming to limit losses for its futures-related insurance fund.

Wirtschaftliche Folgen des Gaspreisanstiegs für die deutsche Industrie

Matthias Mertens, Steffen Müller
IWH Policy Notes, No. 2, 2022
Abstract
Diese Analyse nutzt amtliche Mikrodaten für die deutsche Industrie. Auf Ebene fein untergliederter Produkte werden der Verbrauch an Erdgas und der heimische Produktumsatz mit Daten der Vereinten Nationen zu Exporten und Importen verknüpft. Es zeigt sich, dass die 300 Produkte mit dem höchsten Gasverbrauch innerhalb der deutschen Industrie für knapp 90% des Gasverbrauchs der Industrie stehen, dass bei Gaspreiserhöhungen um das Vierfache gegenüber den Jahren 2015-2017 die Kosten für das durchschnittliche Produkt um 12 Cent pro Euro Umsatz steigen und dass ein Produktionsstopp der Produkte, die sowohl überdurchschnittlich gasintensiv sind als auch überdurchschnittlich leicht durch Importe substituiert werden können, 26% des Gesamtgasverbrauchs der Industrie einspart, aber weniger als 3% des Umsatzes der Industrie kostet.

Hedge Fund Activism and Internal Control Weaknesses

David Folsom, Iftekhar Hasan, Yinjie (Victor) Shen, Fuzhao Zhou
China Accounting and Finance Review, No. 4, 2022
Abstract
Purpose: The aim of the paper is to investigate the associations between hedge fund activism and corporate internal control weaknesses. Design/methodology/approach: In this paper, the authors identify hedge fund activism events using 13D filings and news search. After matching with internal control related information from Audit Analytics, the authors utilize ordinary least square (OLS) and propensity score matching (PSM) to analyze the data. Findings: The authors find that after hedge fund activism, target firms report additional internal control weaknesses, and these identified internal control weaknesses are remediated in subsequent years, leading to better financial-reporting quality. Originality/value: The findings indicate that both managers and activists have incentives to develop a stronger internal control environment after targeting.
