From standard portfolio-choice theory, it is well-understood that background risk, primarily due to wage risk, is one of the central determinants of individuals’ portfolio composition: higher background risk reduces risky investments. However, if background risk is negatively correlated with financial market risk, higher background risk implies a more risky investment. We quantify the influence of ...

In a case study for Germany, this work investigates to which extent price spikes can be attributed to changes in upstream commodity prices, and to which degree strategic behavior by generators may have contributed to the situation. Electricity markets are more prone to the effects of such behavior if ...

Sweden is at the forefront of the transition of its energy sector to low-carbon technologies with profound consequences for both energy generation and its distribution. However, the impact of this transition on the performance of Electricity Distribution System Operators (DSOs) has not been thoroughly studied. The article addresses this gap by using a novel approach and detailed georeferenced firm-level, ...

The advent of cloud computing promises to improve the way firms use IT solutions. Firms are expected to replace large and inflexible fixed-cost investments in IT with more targeted, variable spending on cloud solutions. This is also expected to increase firms' productivity by allowing them to quickly adapt their IT infrastructure to their specific needs. We assess this claim using firm-level data provided ...

Aligned with the war in Ukraine, Russia has significantly withheld natural gas exports to Europe since 2021. As there are no EU-wide sanctions on imports of Russian natural gas, the Ukraine transit as well as imports via Turkey and LNG have remained active during 2022–24. However, the Russian-Ukrainian transit agreement expires at the end of 2024 and discussions about new sanctions on natural gas as ...

By the end of the Second World War, an estimated 20% of the West German housing stock had been destroyed. Building on a theoretical life-cycle model, this paper examines the persistent consequences of the war for individual wealth across generations. As our empirical basis, we link a unique historical dataset on the levels of wartime destruction in 1739 West German cities with micro data on individual ...

There is growing interest in understanding how gender influences the accumulation of wealth. While prior studies focused on labor-related determinants, our research focuses on inheritances and gifts. Using unique survey data that oversamples the top 1% of wealth holders in Germany, we show that the gender wealth gap is small for individuals up to age 40, then widens, and declines for those past retirement ...

Based on a panel dataset of GPS-tracked trips collected before and during the price intervention from a representative sample of 276 individuals, ...
