Is Risk the Fuel of the Business Cycle? Financial Frictions and Oil Market Disturbances
Christoph Schult
IWH Discussion Papers,
Nr. 4,
2024
Abstract
I estimate a dynamic stochastic general equilibrium (DSGE) model for the United States that incorporates oil market shocks and risk shocks working through credit market frictions. The findings of this analysis indicate that risk shocks play a crucial role during the Great Recession and the Dot-Com bubble but not during other economic downturns. Credit market frictions do not amplify persistent oil market shocks. This result holds as long as entry and exit rates of entrepreneurs are independent of the business cycle.

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.

The Income Elasticity of Mortgage Loan Demand

Special Issue: 2016 Portsmouth – Fordham Conferenc

Abstract
One explanation for the emergence of the housing market bubble and the subprime crisis is that increases in individuals’ income led to higher increases in the amount of mortgage loans demanded, especially for the middle class. This hypothesis translates to an increase in the income elasticity of mortgage loan demand before 2007. Using applicant‐level data, we test this hypothesis and find that the income elasticity of mortgage loan demand in fact declines in the years before 2007, especially for the mid‐ and lower‐middle income groups. Our finding implies that increases in house prices were not matched by increases in loan applicants’ income.

Agrarrohstoffpreise und Lebensmittelpreise in armen Ländern
Oliver Holtemöller
Wirtschaft im Wandel,
Nr. 1,
2016
Abstract
In der Politik und in den Medien wird darüber diskutiert, ob spekulativer Handel mit Agrarrohstoffen den Hunger in der Welt vermehrt. In diesem Aufsatz wird untersucht, in welchem Umfang sich Schwankungen von Agrarrohstoffpreisen auf nationale Verbraucherpreise für Lebensmittel in Indien als einem großen Land mit einem großen Anteil an armen Menschen übertragen. Es wird gezeigt, dass Agrarrohstoffpreisschwankungen mit einem Quartal Verzögerung signifikante Effekte auf die Verbraucherpreisinflation für Lebensmittel und die Verbraucherpreisinflation insgesamt in Indien haben. Quantitativ bedeutend waren diese Effekte etwa 2007/2008 und 2010/2011. Aufgrund der restriktiven Reaktion der indischen Zentralbank auf einen Anstieg der Verbraucherpreisinflation kommt es zusätzlich zu negativen Auswirkungen auf die Konjunktur. Allerdings sind andere Faktoren für die Schwankungen der Lebensmittelpreise in Indien wesentlich bedeutender.

Efficiency in the UK Commercial Property Market: A Long-run Perspective
Steven Devaney, Oliver Holtemöller, R. Schulz
IWH Discussion Papers,
Nr. 15,
2012
Abstract
Informationally efficient prices are a necessary requirement for optimal resource allocation in the real estate market. Prices are informationally efficient if they reflect buildings’ benefit to marginal buyers, thereby taking account of all available information on future market development. Prices that do not reflect available information may lead to over- or undersupply if developers react to these inefficient prices. In this study, we examine the efficiency of the UK commercial property market and the interaction between prices, construction costs, and new supply. We collated a unique data set covering the years 1920 onwards, which we employ in our study. First, we assess if real estate prices were in accordance with present values, thereby testing for informational efficiency. By comparing prices and estimated present values, we can measure informational inefficiency. Second, we assess if developers reacted correctly to price signals. Development (or the lack thereof) should be triggered by deviations between present values and cost; if prices do not reflect present values, then they should have no impact on development decisions.

Investor Rationality and House Price Bubbles: The Case of Berlin and the German Reunification
Oliver Holtemöller, R. Schulz
German Economic Review,
2010
Abstract
We analyze the behavior of investors in the Berlin rental apartment house market over the years 1980–2004. Using constant-quality multipliers (price–rent ratios), we reject the hypothesis that multipliers in the market were set in a rational manner. Supported by narrative evidence, we conjecture that investors misjudged the economic effects of the German reunification. To examine this, we employ a stylized structural economic model and analyze the effects of shocks on rational multipliers. It seems that investors confused the reunification with a permanent supply side shock to the economy. By basing their investment decisions on this misjudgement, investors behaved irrationally, but in a very uncertain and unprecedented environment.
