No full textPretty biased? : how physical appearance shapes patterns of ethno-religious discrimination
Full text linkHumans make lasting impressions of others based on physical appearance. While this is often benign, appearance can also signal membership in various social groups. Each of these groups may be associated with stereotypes, which can lead people to act in discriminatory ways. In this dissertation, I explore the intersection of physical attractiveness and cues of ethno-religious identity related to three primary outcomes: wage setting, hiring, and trustworthiness perceptions. By studying the effects of appearance at the level of interpersonal beliefs, perceptions, and expectations, this dissertation aims to identify possible mechanisms that drive group-level inequalities
Essays in monetary economics
Full text linkMonetary policy plays a central role in stabilizing inflation, mitigating business cycle fluctuations, and responding to financial crises. Its effectiveness derives from the broad influence of nominal interest rates on aggregate economic activity. However, different regions within a country or currency union may react differently to the same monetary policy impulse due to regional heterogeneities. A strong form of regional heterogeneities can be found in housing markets. Furthermore, it is well known that expectations about asset prices, and house
prices in particular, violate the rational expectations hypothesis. Instead, a large empirical literature has documented that asset price expectations. experience extrapolative dynamics. In this thesis, I make progress in understanding the transmission and conduct of monetary policy in the presence of regional heterogeneities and extrapolative house price expectations
Policy support for electrolytic hydrogen: Impact of alternative carbon accounting rules
Full text linkGovernments worldwide have recently launched policy support programs for hydrogen, where the level of support is to be tied to the carbon intensity of the hydrogen produced. Here we analyze the impact of alternative accounting rules for assessing the carbon intensity of electrolytic hydrogen on the financial and emission performance of Power-to-Gas (PtG) systems. We initially calibrate our model to reference plants eligible for the production tax credit specified under the Inflation Reduction Act in the United States. Contrary to
common beliefs, we find that more stringent accounting rules provide investors with sufficient incentives to invest in PtG systems today. Yet, they can still lead to life-cycle average carbon intensity levels close to those for hydrogen produced from natural gas with carbon capture. Less stringent rules generally entail higher investment incentives but also significantly higher emissions. Overall, our findings reflect the incentives for investors to utilize capacity by procuring additional, carbon-intensive electricity from the general grid

Chat groups as local civic infrastructure: A case study of “Solidary neighborhood help” Telegram groups during the COVID-19 pandemic in Germany
Full text linkMessaging groups are emerging as “meso-spaces”—digital environments that enable sustained dialogue and collective action through their distinct affordances. We examine how such spaces facilitate civic self-organization through their hybrid online/offline, public/private, and local/global dynamics and how they function as local civic infrastructure during times of crisis. Using a mixed-methods analytical approach, we examined 47 public Telegram groups from Germany during the COVID-19 pandemic. We identified a fundamental tension between political discussion and practical help in these spaces, resolvable through active horizontal participation (including norm negotiation and self-moderation), or strict vertical moderation. Additional challenges included a lack of access to vulnerable groups and limited outreach to local civil society actors, both of which hindered group activity and structural connections within local civic infrastructure. Despite these challenges, our study highlights the potential of local chat groups for self-organization, albeit primarily among privileged urban individuals. We discuss the implications for democratic theory and practice
