Five Essays in Macroeconomics

Heterogeneous-Agent New Keynesian models (HANK)---which replace the representative household by a whole distribution of households---are the about to become the new state-off-the-art model of modern monetary economics because they allow for more realistic consumption patterns of households and a rich description of income and wealth distributions. This PhD thesis contributes to the ongoing advancements ...

(Re)Integrating Radioactive Materials and Waste into a Global Sustainable Development Context

The 17 Sustainable Development Goals (SDGs) of the United Nations, established in 2015, aim to achieve global sustainability by 2030 through the improvement of environmental, social, and economic parameters. However, unlike earlier concepts such as the Agenda 21 of 1992, the SDGs overlook radioactive waste management and related challenges of radiation itself. First, we investigate the historic consideration ...

Measuring the Dunkelflaute: How (not) to Analyze Variable Renewable Energy Shortage

As variable renewable energy (VRE) sources increasingly gain importance in global energy systems, there is a growing interest in understanding periods of VRE shortage ('Dunkelflauten'). Defining, quantifying, and comparing such shortage events across different renewable generation technologies and locations presents a surprisingly intricate challenge. Various methodological approaches exist in different ...

Paying Income Tax after a Natural Disaster

We investigate the effects of a climatic shock on individuals’ tax deduction and tax payable patterns, alongside their income dynamics. Using individual-level annual tax return data and exploiting the 2010–2011 Queensland Floods in Australia as a natural experiment, we find that the floods affect different income groups differently. They also lead to persistent higher tax deductions for high-income ...

Revisiting Investment Costs for Green Steel: Capital Expenditures, Firm Level Impacts, and Policy Implications

The transition of the steel sector to carbon neutrality requires significant investment. In this study, we aim to better understand the scale of investment required for a transition to hydrogen-based steelmaking and the ability of listed steelmakers to finance this investment. First, we analyze how capital expenditures are estimated in the academic literature and compare them with reported investment ...

Questioning Nuclear Scale-up Propositions: Availability and Economic Prospects of Light Water, Small Modular and Advanced Reactor Technologies

This paper addresses the pressing need for rapid decarbonization of energy systems by examining the role of nuclear power in future energy scenarios collected in the IPCC database. Despite their explorative character, energy scenarios can influence decision-makers or might be used to promote certain technology developments. They are increasingly subject to the integration into real-world settings and ...

Avoid, Shift or Improve Passenger Transport? Impacts on the Energy System

New Trade Models, Same Old Emissions?

This paper investigates the elusive role of productivity heterogeneity in new trade models in the trade and environment nexus. We contrast the Eaton-Kortum and the Melitz models with firm heterogeneity to the Armington and Krugman models without heterogeneity. We show that if firms have a constant emission share in terms of sales — as they do in a wide range of trade and environment models — the three ...

Heat Transition: Municipalities Need Federal Support in Decommissioning Natural Gas Networks

Large parts of the existing natural gas distribution networks must be decommissioned due to the decarbonization of the heat supply. However, there are neither regulatory nor economic incentives for the gas network operators to do so and delaying the decommissioning could be expensive for the remaining customers. This Weekly Report analyzes to what extent municipalities can partially decommission the ...

Exploring the Interdependence of Climate, Finance, Energy, and Geopolitics: A Conceptual Framework for Systemic Risks Amidst Multiple Crises

Navigating the transition toward a zero-emission and just future amidst multiple crises requires a nuanced understanding of potential hindrances to investments and energy transitions. As current approaches hardly consider the big picture of interacting crises, this study offers a framework to analyze the dynamics and risk channels between 1) the climate crisis, 2) financial (in)stability, 3) the geopolitical ...
