    <description>Title: Institutional reform and depositors' portfolio choice evidence from bank account data
Authors: Berlemann, Michael; Luik, Marc-André
Abstract: In this paper we employ the natural experiment of German Division and Reunification in order to study the effect of institutional reform on the decision to hold risky assets. We present empirical evidence indicating that even 16 years after German Reunification risky portfolios of East and West German bank customers differed systematically, even after controlling for wealth and other socio-demographic factors. While these differences are especially pronounced for bank customers with experiences in the former communist system, even the younger generation of East Germans still differs remarkably from their West German counterparts in terms of risky asset choice. Thus, informal institutions tend to have long-lasting effects on portfolio behavior.</description>

    <description>Title: On Bremen's industrial transformation: The role of hydrogen in production
Authors: Sacht, Stephen; Wedemeier, Jan
Abstract: Hydrogen serves as an energy source and represents an important cornerstone for achieving the goal of maintaining a level of zero-carbon-dioxide emissions in industry production processes. Our analysis is based on the computable general equilibrium framework and focuses on a partial switch to hydrogen used in production in northern Germany, particularly in the Bremen region. The simulation results indicate that Bremen's chemical, steel, and copper industries could replace up to 1.5, 15, and 35%, respectively, of petroleum and natural gas with hydrogen, without negative effects on overall production, until 2032. The share of electricity based on renewable sources in the production of hydrogen amounts to approximately 74%. This step can be seen as required for the production of green hydrogen, i.e., in the absence of fossil energy sources.</description>

    <description>Title: Not in my postcode? Wind turbines and U.S. presidential approval
Authors: Eurich, Marina
Abstract: The expansion of wind power has the potential to make a major contribution to the mitigation of climate change. While wind power generates positive externalities at the global level by reducing carbon dioxide, it also generates negative externalities at the local level, such as noise pollution from sound emissions. This paper analyses whether sound emissions from wind turbines have an effect on the popularity of the incumbent government. It thereby exploits the exogenous temporal and spatial variation in wind speed as a measure of sound emissions from wind turbines and combines it with high-frequency zip-code-level survey data for the United States. The results demonstrate that sound emissions from wind turbines lead to a decrease in the popularity of the (pro-renewables) President Barack Obama. This effect is temporal, diminishes with distance from wind turbines, and is driven exclusively by individuals identifying as Democrats. Furthermore, individuals who are older, have lower levels of education, or live in rural areas and small towns exhibit a more negative reaction. In order to maintain public support for the energy transition, it is essential that policymakers take these local impacts into account.</description>

    <description>Title: Moment matching for Bayesian inference in the baseline New-Keynesian model
Authors: Jang, Tae-Seok; Sacht, Stephen
Abstract: Contrary to claims in studies on financial economics, a sparse database often obscures the identification of parameters in macroeconomic models. These identification problems originate from the poorly defined mapping between a structural model and reduced-form parameters. Hence, researchers rely on prominent estimation methods, such as Bayesian approaches, which require sound knowledge of prior distributions on parameters. These approaches, however, are characterized by a flat likelihood and/or a posterior distribution driven mainly by prior information. To alleviate identification issues, we apply approximate Bayesian computation combined with the choice of specific moment conditions. This estimation approach not only allows for circumventing high dimensional likelihood functions but also avoids parameter identification problems given the use of a bootstrap method. Our estimation method is successfully applied to a hybrid version of the New Keynesian model.</description>
