Abstract: Electricity markets are increasingly shaped by uncertainty in residual demand due to renewable expansion. This weakens the disciplining role of forward markets and amplifies the potential for market power in spot pricing. Understanding this mechanism is essential for informed market design in the context of growing intermittency and structural transformation of energy systems.
This work presents a multi-stage stochastic optimization model to analyze price dynamics and reliability of supply in a 100% renewable power system. The stochastic framework captures uncertainty arising from the intermittency of weather-dependent renewable energy sources and compares three market design options for a future fully renewable German electricity market: an energy-only market without...
This paper identifies a risk-hedging mechanism we coin the "dirty self-hedge" and analyzes how it affects financing costs of green industrial investments. The dirty self-hedge occurs in basic materials production when exclusively conventional, emission-intensive producers can pass on input price shocks to final product prices. They thus have a natural hedge for their profit margins against input...
The open science movement has gained significant momentum over the past decade, with pre-registration and the use of pre-analysis plans being central to ongoing debates. Combining observational evidence on trends in adoption with survey data from 519 researchers, this study examines the adoption of pre-registration in experimental economics. Pooling statistics from 19 leading journals published between ...

Die Nutzung sozialer Medien durch Kinder und Jugendliche wird zunehmend kontrovers diskutiert. Im Fokus stehen dabei Risiken, Chancen und mögliche Regulierungen. Mittlerweile zeigen sich Politiker*innen aller relevanten Parteien offen für ein Social-Media-Verbot bis zu einem bestimmten Alter; das Bundesfamilienministerium hat eine Expert*innenkommission eingesetzt. Auf Basis einer Kurzbefragung im ...
