Entrepreneurs tend to be risk tolerant but is higher risk tolerance always better? In a sample of about 2100 small businesses, we find an inverted U-shaped relation between risk tolerance and profitability. This relationship holds in a simple bilateral regression, and even after controlling for a large set of individual and business characteristics. Apparently, one major transmission goes from risk ...

Background The harmful mental health effects of perceived discrimination for migrant populations are well established. The potential buffering effect of regional-level social capital, however, has not previously been explored. Methods Using data from the German Socio-Economic Panel (SOEP; 2009–2018) we apply multilevel models to assess the effect of frequent or infrequent perceived discrimination on ...

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, ...

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 ...

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 ...

This study analyses travellers’ behavioural responses to two temporal measures implemented by the German government: the reduction in public transport prices, making it almost fare-free, and a decrease in fuel taxes to the minimum level permitted by European law. Based on a panel dataset of GPS-tracked trips collected before and during the price intervention from a representative sample of 276 individuals, ...

We employ a control function methodology, complemented by various identification strategies, to causally estimate the heterogeneous effects of broadband availability on firms’ total factor productivity (TFP) across 46 two-digit manufacturing and service industries in Germany from 2010 to 2015. Throughout this period, the availability of broadband, defined as access to transmission rates of at least ...

During the 2022 energy crisis, electricity prices across Europe have risen to unprecedented heights. 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 ...

Theory suggests that corporate and sovereign bonds are fundamentally different, also because sovereign debt has no bankruptcy mechanism and is hard to enforce. We show empirically that the two assets are more similar than you think, at least when it comes to high-yield bonds over the past 20 years. We use rich new data to compare high-yield US corporate (“junk”) bonds to high-yield emerging market ...
