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 ...

Large-scale socio-economic panel studies aim to document societal trends and public opinions using representative population samples. Despite the profound impact of artificial intelligence (AI) on public and private life across diverse contexts, these studies have rarely addressed the use and evaluation of AI for individual respondents. Therefore, a standardized assessment instrument is introduced ...

What kind of earnings mobility regime defines our society? Are individuals’ earnings trajectories primarily shaped by their social class position, or do trajectories vary within them? These unresolved questions lie at the heart of debates on social class and labor market rewards. To address them, we leverage employment relations theory and data from the German Socio-Economic Panel. We use mixed effects ...

Research has conceptualized system justification as an overall perception of legitimacy of the status quo. However, there is mixed evidence to determine whether individuals construe political systems and values that uphold them as part of such status quo. We reasoned that if individuals construe the status quo as encompassing the political system and its values in the United States, system justification ...

Using long running panel data spanning at least 15 years from Australia, Germany and the UK, this study investigates longitudinal age–wellbeing trajectories by the Big Five personality traits. We estimate within person (fixed effects) models separately for each country and for low/high trait subgroups, producing 30 distinct trajectories. Across all subgroups, we found the same ageing pattern: a decline ...

In 2001, Germany abolished public occupational disability insurance (ODI)—the second tier of its public DI system—for cohorts born after 1960. Using administrative data, we first document that, in the long run, overall DI inflows declined by roughly one-third. Second, using representative survey data, we document at best modest ODI insurance take-up responses in the private individual, risk-rated market, ...

We study the role of social image in influencing lying behavior through a pre-registered within-subject experiment embedded in the 2020 wave of the German Socio-Economic Panel Innovation Sample (SOEP-IS). By exogenously manipulating the observability of lying across two tasks, we explore how individuals respond to increased image costs of lying. By exploiting the rich comprehensive socio-demographic ...

Job-related relocations are common. Standard economic models typically treat workers as isolated individuals, while most workers live and move as part of a couple. Using a dynamic event study with synthetic comparison groups and German data, we show that women within couples frequently become “tied movers”: following relocation, male partners experience substantial earnings gains (as both hourly wages ...
