    A Collective Blueprint, Not a Crystal Ball: How Expectations and Participation Shape Long-Term Energy Scenarios

    The development of energy systems is not a technocratic process but equally shaped by societal and cultural forces. Key instruments in this process are model-based scenarios describing a future energy system. Applying the concept of fictional expectations from social economics, we show how energy scenarios are tools to channel political, economic, and academic efforts into a common direction. To impact ...

    Have the Effects of Shocks to Oil Price Expectations Changed? Evidence from Heteroskedastic Proxy Vector Autoregressions

    Studies of the crude oil market based on structural vector autoregressive (VAR) models typically assume a time-invariant model and transmission of shocks or they consider a time-varying model and shock transmission. We assume a heteroskedastic reduced-form VAR model with time-invariant slope coefficients and test for time-varying impulse responses in a model for the global crude oil market that includes ...

    Stranded Nations? Transition Risks and Opportunities towards a Clean Economy

    The transition away from a fossil-fuel powered economy towards a cleaner production system will create winners and losers in the global trade system. We compile a list of 'brown' traded products whose use is highly likely to decline if the world is to mitigate climate change, and explore which countries are most at risk of seeing their productive capabilities 'stranded'. Using methods from economic ...

    Replacing Gas Boilers with Heat Pumps Is the Fastest Way to Cut German Gas Consumption

    The supply security of fossil gas has been disrupted by the Russo-Ukrainian War. Decisions to relocate the production and transport of gas have become so urgent that new long-term contracts are imminent that undermine the Paris Climate Agreement. Here, we simulate how quickly the addition of renewable electricity and the installation of heat pumps can substitute enough gas to reduce supply risk, while ...

    The Price of Natural Gas Dependency: Price Shocks, Inequality, and Public Policy

    The 2022 natural gas price spikes across Europe raised concerns regarding their distributional consequences. This paper investigates the distributional effect of price increases between and, in particular, within different income groups in Germany, accounting for different determinants of gas expenditures. The study finds that low-income households are affected the most by the gas price increase. Low-income ...

    The Energy-Price Channel of (European) Monetary Policy

    This study examines whether central banks can combat inflation that is caused by rising energy prices. By using a high-frequency event study and a Structural Vector Autoregression, we find evidence that the European Central Bank (ECB) and the Federal Reserve (Fed) are capable of doing so by affecting domestic and global energy prices. This “energy-price channel” of monetary policy plays an important ...

    And Yet They Move: Energy Prices Fall When Key Interest Rates Increase, Despite Countervailing Effects

    Energy prices have risen sharply as a result of the coronavirus pandemic as well as the Russian attack on Ukraine in February 2022. The resulting consumer price inflation is forcing the European Central Bank (ECB) to act in accordance with its mandate. However, the ECB expresses doubts that it will be able to have an impact on the price increases. As this Weekly Report based on an analysis of structural ...

    International Partnerships for a Just Energy Transition: Findings from South Africa

    In 2021, the G7 and South Africa agreed upon the Just Energy Transition Partnership (JETP). This new instrument in international cooperation should support emerging and developing economies in a just energy transition and in phasing out coal. It is intended to facilitate equal partnerships between donors and recipients, thereby also facilitating the energy transition. An evaluation of the South African ...

    How Communication Makes the Difference between a Cartel and Tacit Collusion: A Machine Learning Approach

    This paper sheds new light on the role of communication for cartel formation. Using machine learning to evaluate free-form chat communication among firms in a laboratory experiment, we identify typical communication patterns for both explicit cartel formation and indirect attempts to collude tacitly. We document that firms are less likely to communicate explicitly about price fixing and more likely ...

    Reducing Energy System Model Distortions from Unintended Storage Cycling through Variable Costs

    Energy system models are used for policy decisions and technology designs. If not carefully used, models give implausible outputs and mislead decision-making. One implausible effect is “unintended storage cycling”, which is observable as simultaneous storage charging and discharging. Methods to remove such misleading effects exist, but are computationally inefficient and sometimes ineffective. Through ...
