TY - GEN A1 - Hoffmann, Christin A1 - Stephan, Gunter T1 - Regional Flood Impacts and Adaptation in a Federal Setting: A spatial computable general equilibrium analysis for Switzerland T2 - Climate Change Economics N2 - Climate change, a growing population and inappropriate land use may lead to a significant increase in the frequency, intensity and the duration of water-related extreme events. We aim (1) to gain a better understanding of the direct and indirect economic impacts of floods, (2) to analyze the issue of efficient flood adaption as well as the issue of financing adaptation in a federalist system, where local and national governmental authorities interplay in the provision of local public good adaptation. Our numerical thought experiments are based on a dynamic, spatial differentiated Ramsey type Computable General Equilibrium Model. Regions are determined by exposure and vulnerability to floods and are not identical with territorial units. Our results indicate: (1) general equilibrium effects caused by flood damages in vulnerable regions lead in regions of low vulnerability also to considerable welfare and GDP losses. (2) Providing local public good adaptation can at low economic costs significantly reduce negative impacts on welfare, GDP as well as the allocation of resources between regions and sectors. (3) Funding adaptation by imposing a regional land tax should be preferred to a national output tax or a combination of both with transfers from national to regional governments.

The Pace of Life approaches an individual’s exposure to time and is an intensively studied concept in the evolutionary biology research. Albeit overall rarely, it is increasingly used to understand human behavior and may fulfill many criteria of a personal trait. In a controlled laboratory environment, we measured the participants’ Pace of Life, as well as their performance on a real-effort task. In the real-effort task, the participants had to encode words, whereby each word encoded correctly was associated with a monetary reward. We found that individuals with a faster Pace of Life accomplished more tasks in total. At the same time, they were less accurate and made more mistakes (in absolute terms) than those with a slower Pace of Life. Thus, the Pace of Life seems to be useful to identify an individual’s stance on the speed-accuracy continuum. In our specific task, placing more weight on speed instead of accuracy paid off: Individuals with a faster Pace of Life were ultimately more successful (with regard to their monetary revenue).

Social acceptance of these investments is required in order to implement hydrogen technologies as fast and efficiently as possible. This study investigates which benefits associated with green hydrogen foster its social acceptance. Using a between-subject design, we implement two different treatments. Both treatments have in common that the participants experience the transformation into a hydrogen economy in a virtual reality scenario. In "Info Security of Supply", we provide the participants information about the benefits of green hydrogen regarding the security of energy supply and climate protection. In Control, we inform them only about the benefits of climate protection. Subsequently, the participants decide about the financial support of a hydrogen project. Our preliminary results show a higher support if the focus is solely on the positive impact of green hydrogen for climate protection.

Using a Differences-in-Differences approach, we find that (1) wind turbines reduce prices significantly, (2) solar fields have no significant impact, and (3) conventional plants over 1 km away show positive net effects. We set out to explain this result by disentangling the positive local external effects of energy generation, which we measure in terms of local purchasing power and tax revenues. Our results show that the commissioning of conventional power stations results in a significant increase in both purchasing power and business tax income in the vicinity. We thus conclude that significant financial participation of the local public in the development of renewable energy projects, especially wind turbines, could be key to increasing their acceptance and accelerating their expansion.

We interpret a causal impact of bioenergy plant commissioning on housing prices in their vicinity as the average net external effects for residents. We utilize bioenergy plant construction data in Germany between 2007 and 2022 as a quasi-experiment with naturally occurring control groups in their vicinity and apply recently improved difference-in-difference estimation procedures to analyze instantaneous and heterogeneous treatment effects. We find a significant and negative impact on housing prices if plants use gaseous biofuel, generate electricity on-site, and are medium-sized. The magnitude of the effect is comparable to those for solar fields. In contrast, we find no impact for small and large bioenergy plants and those that use solid or liquid biofuels.

Evidence from a field experiment T2 - Journal of Economic Behavior & Organization N2 - Giving performance feedback to increase employee productivity has shown ambiguous results: Many laboratory studies have demonstrated a statistically significant effect of feedback on performance, but the effect is less evident in the field. In addition, the effects of digital feedback are not well understood. This feedback differs from other types of feedback as it is personalized, but not generated and provided by another human, e.g., the supervisor, but by a machine. We conducted a field experiment in which we introduced digital feedback to improve truck drivers' performance by enhancing their energy-efficient driving behavior. Our results show that digital feedback led to a statistically significant but small overall improvement in energy efficiency and performance that is driven by the improvement of initially very good- and very bad-performing drivers. This effect is robust, even when considering the differences in the room for improvement relative to the initial performance.
