Uncertainties in Estimating Production Costs of Future Nuclear Technologies: A Model-based Analysis of Small Modular Reactors

Predicting future costs of technologies not yet developed is a complex exercise that includes many uncertain parameters and functional forms. In that context, small modular reactor (SMR) concepts that are in a rather early development stage claim to have cost advantages through learning effects, standardized design, modularization, co-siting economies, and other factors, such as better time-to-market ...

Bidirectional Coupling of the Long-term Integrated Assessment Model REgional Model of INvestments and Development (REMIND) v3.0.0 with the Hourly Power Sector Model Dispatch and Investment Evaluation Tool with Endogenous Renewables (DIETER) v1.0.2

Integrated assessment models (IAMs) are a central tool for the quantitative analysis of climate change mitigation strategies. However, due to their global, cross-sectoral and centennial scope, IAMs cannot explicitly represent the temporal and spatial details required to properly analyze the key role of variable renewable energy (VRE) in decarbonizing the power sector and enabling emission reductions ...

Using Within-Person Change in Three Large Panel Studies to Estimate Personality Age Trajectories

How does personality change when people get older? Numerous studies have investigated this question, overall supporting the idea of so-called personality maturation. However, heterogeneous findings have left open questions, such as whether maturation continues in old age and how large the effects are. We suggest that the heterogeneity is partly rooted in methodological issues. First, studies may have ...

Competition and Moral Behavior: A Meta-Analysis of Forty-Five Crowd-Sourced Experimental Designs

Does competition affect moral behavior? This fundamental question has been debated among leading scholars for centuries, and more recently, it has been tested in experimental studies yielding a body of rather inconclusive empirical evidence. A potential source of ambivalent empirical results on the same hypothesis is design heterogeneity—variation in true effect sizes across various reasonable experimental ...

Hours Risk and Wage Risk: Repercussions over the Life Cycle

We decompose earnings risk into contributions from hours and wage shocks. To distinguish between hours shocks, modeled as innovations to the marginal disutility of work, and labor supply reactions to wage shocks, we formulate a life-cycle model of consumption and labor supply. For estimation, we use data on married American men from the Panel Study of Income Dynamics. Permanent wage shocks explain ...

Kompromiss zur Kindergrundsicherung ist eine verpasste Chance

Income-Based Family Typology and Child Development: Evidence from the UK

Our paper contributes to the literature studying how household conditions can influence children’s development, focusing on the type of family model where children grow up, defined on the basis of parental employment status and relative earnings. The traditional “male-breadwinner” model is no longer the only type of family that has been observed throughout recent decades; the “dual-breadwinner” family ...

Fünf Mythen zu Kinderarmut und Kindergrundsicherung

Finanzminister Christian Lindner bringt neue Argumente gegen die Kindergrundsicherung in den Diskurs ein. Doch sie beruhen auf Missverständnissen. Zeit, sie auszuräumen. Im öffentlichen Diskurs über die Kindergrundsicherung nennt Bundesfinanzminister Christian Lindner zwei neue Argumente: Die Entwicklung der Kinderarmut in Deutschland seit 2015 sei dahingehend positiv, dass viele "ursprünglich deutsche ...
