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 ...
We fit CES and VES production functions to data from a numerical bottom-up optimization model of electricity supply with clean and dirty inputs. This approach allows for studying high shares of clean energy not observable today and for isolating mechanisms that impact the elasticity of substitution between clean and dirty energy. Central results show that (i) dirty inputs are not essential for production. ...
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 ...
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 ...
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 ...
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 ...
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 ...
By Wolf-Peter Schill and Alexander Roth This page provides a brief overview of the current status of all indicators included in the Ampel-Monitor Energiewende. More detailed methodological explanations and data sources can be found on the homepage of the Ampel-Monitor and in the introductory DIW Weekly Report 27/2022. All underlying data are also available in the Open Energy Tracker, where they are ...
