Demand for renewable resources
Full text linkIn the first paper, we show that a lower importance of catch in recreational fishing may result in higher catches. While this effect also holds under first-best management, it may destabilize open-access recreational fisheries to the point of stock collapse. The second paper analyzes the political economy of resource management. We show that resource users (the processing industry, consumers) and factor owners (capital and labor employed in resource harvesting) may favor inefficiently high harvest rates up to open-access levels. This may explain why public resource management is often very inefficient. The third paper models trade in renewable resources as stipulated not only by autarky price differences, but also by consumers' love of variety. We show that the love-of-variety effect enables welfare gains from trade even if total consumption decreases. Total consumption may decrease because the love of variety weakens the link between resource scarcity and demand
Studies and Experiments on Information Asymmetries and the Intergenerational Free Rider Problem in Climate Change
Full text linkClimate change presents critical economic and environmental challenges, exacerbated by information asymmetries and intergenerational free-rider problems. This dissertation explores these issues through theoretical analysis and experimental research. The first part examines the difficulties firms face in accurately reporting greenhouse gas (GHG) emissions, particularly Scope 3 emissions, and how primary data sharing can enhance transparency, reduce carbon risks, and improve investment decisions. The second part presents experimental studies testing the effectiveness of (self-)verification mechanisms in overcoming information asymmetries in risky investment contexts. The findings suggest that these mechanisms can enhance trust and efficiency in sustainability-related investments. Lastly, the thesis investigates how communication and punishment strategies influence intergenerational cooperation, providing insights into behavioral and institutional solutions for long-term climate action. The research contributes to a better understanding of market failures in climate policy and offers practical tools to enhance sustainability governance and investment strategies
Optimal global carbon management withocean sequestration
Full text linkThe papers in this cumulative thesis deals with questions which arise from the inclusion of the oceanic carbon sink into economic analyses about climate change. First, what is an appropriate description of the global carbon cycle, in particular with respect to the oceanic carbon sink in economic models? Second, since natural forces transport carbon into the deep ocean where it affects society less adversely than in the atmosphere, the logical question is: Which carbon removal measures can be applied to accelerate the process of downward carbon transfer? Third, to integrate these measures into economic optimization, how can the carbon uptake be measured and verified, how can carbon credits be assigned, and how to deal with carbon that it is only temporarily stored and expected to leak back into the atmosphere at some point in the future? Fourth, what are the critical costs and critical carbon amounts to be removed from the atmosphere in order to provide an option for climate change mitigation in comparison to existing options? Fifth, what is the dynamic optimal application of such measures in climate change policy? The papers in this cumulative thesis provide answers to these questions by investigating the role of CDR measures in relation to RM measures, by considering accounting and market requirements to one specific oceanic CDR measure, ocean iron fertilization, and by deriving the dynamic optimal carbon sequestration strategy for various climate policies
Factor input constraints in resource dynamics
Full text linkThis cumulative doctoral thesis consists of four individual research articles. It contributes to different strands of literature, in particular resource, development and energy economics. Research in economics aims to contribute to improved living conditions for the people on this planet. One important question to achieve this addresses the extraction of natural resources over time. First, it is important to assess the welfare society derives from a natural resource in the current state and to see how the availability of other factors of production impacts these benefits. As will be shown in chapter 1, a fishery can generate rents even under open access, if production factors are supplied locally. Second, this assessment should include future benefits' development given environmental and economic changes (chapter 2). Chapters 3 and 4 show that the inter-temporal aspect increases in complexity when factors of production are not flexibly adaptable over time, or when learning-by-doing occurs, such that today's production affects productivity in the future. In summary, numerous constraints affect resource use and production now and in the future. This dissertation addresses some of these constraints in order to help to improve resource management
Optimal Methane Hydrate Exploitation and Repercussions on Climate
Full text linkDiese Arbeit untersucht anhand dreier verschiedener wirtschaftstheoretischer Modelle optimale Abbaustrategien der unkonventionellen Erdgasquelle Methan- oder Gashydrat, die aufgrund der dort vorherrschenden Druck-Temperatur-Verhältnisse vorrangig an den Kontinentalrändern der Ozeane auftritt und dort im Porenraum submariner Sedimente die Bodenfestigkeit erhöht. Die Verbrennung des in den Hydraten gebundenen Gases trägt durch CO2-Ausstoß zur Akkumulation von Treibhausgasen bei, Leckagen aufgrund sogenannter Blow-Outs durch CH4-Emissionen. Eine zweite Externalität tritt auf, da die Entfernung der festen Gashydrate aus den Sedimenten die Kontinentalhänge destabilisiert und das Risiko submariner Hangrutschungen birgt. Kapitel 3 bindet diese beiden Externalitäten wie auch den selbstständigen Abbau der Gashydrate, der aufgrund durch die globale Erwärmung veränderter Umweltbedingungen auftritt und CH4 freisetzt, in ein Modell zur optimalen Nutzung nicht-erneuerbarer fossiler Brennstoffe ein, welches die gesellschaftlichen Schäden infolge erhöhter Treibhausgasbestände in Form einer konvexen Schadensfunktion berücksichtigt. Kapitel 4 untersucht ebenfalls die optimalen dynamischen Abbaupfade eines einzelnen endlichen Ressourcenbestands mit den Eigenschaften von Gashydrat, wobei an die Stelle der konvexen Schadensfunktion hier eine exogen gegebene Beschränkung der atmosphärischen Konzentration von Treibhausgasen tritt. Ein besonderes Augenmerk liegt dabei auf der isoliert betrachteten Wirkung der einzelnen abgebildeten Eigenschaften des Gashydrats und der durch die Obergrenze auferlegten Restriktion. Kapitel 5 untersucht eine mögliche Rolle der Gashydrate im optimalen Energiemix anhand eines Modells, in dem unter Vernachlässigung von Kostenfragen und der zweiten beschriebenen Externalität drei Energiequellen verfügbar sind, deren optimale Reihenfolge der Ausbeutung und deren Abbaupfade bestimmt werden. Es handelt sich um zwei fossile Brennstoffe, Gashydrat und Kohle, die anhand ihrer CO2-Intensität und des selbstständigen Abbaus unterschieden werden, sowie eine emissionsfreie alternative Energieform

Essays on Sustainable Consumer Behavior and the Interaction of Risk and Time Preferences
Full text linkThis dissertation contains five papers on economic behavior that primarily focus on decision-making in the present with consequences for the future. The papers are methodologically diverse and can be subdivided into two independent parts. The first part is focused on two established strands of the behavioral economics literature: time and risk preferences - specifically on their interaction. As contributions to the behavioral economics literature, the three papers in the first part are theory-driven. Specifically, one paper contains an axiomatic analysis of a class of intertemporal risk preferences, and two empirical papers test properties and predictions of said class. Methodologically, the empirical contributions follow the experimental economics convention and are based on laboratory experiments with a specific focus on incentivizing behavior. The second part of this dissertation focuses on consumer decision-making and takes a more psychological approach. This part contains two empirical papers investigating preferences for sustainable consumption, i.e., consumer behavior influencing future resources. The two papers consider physiological influences on consumer behavior, specifically, the influences of hunger and ambient temperatures on decision-making. Methodologically, the two reported lab experiments focus on unincentivized choice behavior and put a focus on the physiological treatment manipulations and the reliability and validity of the measurements of psychological variables
