The Long-Term Implications of Destruction During the Second World War on Private Wealth in Germany

By the end of the Second World War, an estimated 20 percent of the West German housing stock had been destroyed. Building on a theoretical lifecycle model of wealth accumulation, this paper examines the extent to which regional differences in destruction can explain differences in wealth today” – at the beginning of the 21st century. As our empirical basis, we link a unique historical dataset on the ...

Scenario Analysis for Net Zero: The Applicability of Climate Neutrality Studies for Transitioning Firms in the German Building Sector and Energy-Intensive Industry

Various stakeholders are increasingly encouraging companies from the real economy to adopt measures facilitating their transition towards carbon neutrality. In this context, companies are expected to implement forward-looking strategies and climate-related reporting practices using scenario analysis aligned with scientific evidence and credible pathways to net zero carbon emissions. This paper examines ...

Investments in Energy-Efficient Building Renovation Are on a Downward Slide

According to the latest review report of the Council of Experts on Climate Change, the German building sector failed to meet its greenhouse gas emission reduction targets in 2022. This is in part because investments in energy-efficient building refurbishment—supported by all kinds of policy measures— has neither been low nor shown a consistently positive trend over the past ten years. Furthermore, ...

Putting MARS into Space: Non Linearities and Spatial Effects in Hedonic Models

Multivariate Adaptive Regression Spline (MARS) is a simple and powerful non-parametric machine learning algorithm that automatizes the selection of non-linear terms in regression models. In this study, we propose using MARS in a spatial regression framework to account for potential non-linearities and spatial effects in spatial regression models. Using a relatively large data set of 17,000 dwellings ...

Health Implications of Building Retrofits: Evidence from a Population-Wide Weatherization Program

What is the impact of housing upgrades on occupant health? Although economists and policymakers are certain about the health implications of housing upgrades, empirical evidence is largely missing or else only based on small-scale experiments in developing countries. This study provides the first population-representative quasi-experimental estimates based on a large-scale refurbishment program that ...

Government-Made House Price Bubbles? Austerity, Homeownership, Rental, and Credit Liberalization Policies and the “Irrational Exuberance” on Housing Markets

Housing bubbles and crashes are catastrophic events for economies, implying enormous destruction of housing wealth, financial default risks, construction unemployment, and business cycle downturns. This paper investigates whether governmental housing policies can affect economies’ propensity to build up speculative house price bubbles. Specifically, we focus on the liberalization effects of rent and ...

Accelerate Thermal Modernization of Buildings with Minimum Standards for Buildings and Binding Retrofitting Targets

The energy and climate crisis enhance the need for energy savings. In the building sector, these savings can be achieved primarily through thermal retrofitting. So far, progress in this area has been slow. To date, less than one percent of the residential building stock in Germany is retrofitted each year. The existing support programs alone offer too little reliability for the necessary investments ...

Do Rent Controls and Other Tenancy Regulations Affect New Construction? Some Answers from Long-Run Historical Evidence

Construction Boom Coming to an End; Change in Policy Strategy Needed

Following the construction boom of recent years in Germany, inflation and supply bottlenecks hit the industry hard in 2022. While nominal construction volume increased by nearly 14 percent, it decreased by two percent when adjusted for inflation. Residential construction, which is urgently needed, was particularly affected. In 2023 and 2024, it is expected that investors will show restraint and that ...
