Improved Energy Efficiency: Vital for Energy Transition and Stimulus for Economic Growth

As part of the energy transition process, the German government has set far-reaching energy efficiency targets, including doubling the annual rate of building renovation to upgrade energy performance from one to two percent. DIW Berlin has estimated the additional energy-savings-related investment required to meet these targets and analyzed the impact this could have on the economy. In the long term, ...

Wohnsituation von Migrantenhaushalten: eine Analyse mit Blick auf den Effekt der Mietpreisbenachteiligung

In this paper a descriptive overview of the housing situation of immigrants in Germany is combined with a multivariate analysis on potential effects of rental price discrimination for specific groups of immigrants. The driving research question is, whether immigrants systematically pay higher rents for comparable flats. Utilizing data from the German Socio-economic Panel (SOEP) different variables ...

Similar Challenges - Different Responses: Housing Policy in Germany and Russia between the Two World Wars

The World War I played a key role in shaping modern housing policy. While in the pre-War time virtually no housing policy existed, the beginning of hostilities led to an almost immediate and comprehensive state intervention in the housing market, particularly among those engaged in the war. Despite initially similar conditions and challenges induced by the war, housing policy was carried out in different ...

Business Confidence and Forecasting of Housing Prices and Rents in Large German Cities

In this paper, we evaluate the forecasting ability of 115 indicators to predict the housing prices and rents in 71 German cities. Above all, we are interested in whether the local business confidence indicators can allow substantially improving the forecasts, given the local nature of the real-estate markets. The forecast accuracy of different predictors is tested in a framework of a quasi out-of-sample ...

The Residency Discount for Rents in Germany and the Tenancy Law Reform Act 2001: Evidence from Quantile Regressions

Most countries show a residency discount in rents for sitting tenants. In the wake of strong rent increases and housing shortages, Germany implemented a reform in 2001 to curtail rent increases. Based on linked housing-tenant data for Germany, this paper estimates panel OLS and quantile regressions of rents within tenancies. The results show that rents deflated by the CPI increase strongly from 1984 ...

Leisure and Housing Consumption after Retirement: New Evidence on the Life-Cycle Hypothesis

We revisit the alleged retirement consumption puzzle. According to the life-cycle theory, foreseeable income reductions such as those around retirement should not affect consumption. However, we first recall that given higher leisure endowments after retirement, the theory does predict a fall of total market consumption expenditures. In order not to mistake this predicted drop for a puzzle we focus ...

German construction industry booming despite decline in energy-efficient refurbishment

DIW Berlin’s construction volume calculations: construction industry remains a key pillar of the German economy—need for action in energy-efficient refurbishment and in accommodating refugees The construction industry remains a key pillar of the German economy: buildings worth a total of around 338 billion euros will have been constructed or modernized in Germany by the end of this year—2.7 ...

Fifty Shades of State: Quantifying Housing Market Regulations in Germany

The paper aims at measuring the rental housing market regulations in Germany between 1913 and 2015. Four classes of housing policy are considered: Rent controls, tenant protection, rationing of housing, and fostering of social housing. Based on a thorough analysis of federal and regional legislation, for each class, an index is constructed, increasing in degree of regulation. The average of class-specific ...

Small Might Be Beautiful, but Bigger Performs Better: Scale Economies in "Green" Refurbishments of Apartment Housing

The energy efficiency of the residential housing stock plays a key role in strategies to mitigate climate change and global warming. In this context, it is frequently argued that private investment and the quality of thermal upgrades are too low in the light of the challenges faced and the potential energy cost savings. While many authors address the potential barriers for investors to increase energy ...
