Selection, Socialization, and Risk Preferences in the Finance Industry: Longitudinal Evidence for German Finance Professionals

The financial sector plays a crucial role in society. Consequently, prior research has examined the preferences of professionals working in finance. However, these studies have tended to be cross-sectional and have neglected the dynamic roles played by (self-)selection and socialization. This paper uses longitudinal data from Germany to examine how individuals’ financial risk preferences affect their ...

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 ...

Heizenergiebedarf, Heizenergiepreise und Heizausgaben in Zwei- und Mehrparteienhäusern 2020–2022, nach Raumordnungsregionen (interaktive Grafik)

Das DIW Berlin berechnet jährlich auf Basis von Daten des Immobiliendienstleisters ista den temperaturbereinigten Heizenergiebedarf, die Heizenergiepreise und die Heizausgaben in privaten Zwei- und Mehrparteienhäusern in Deutschland. Grundlage der Berechnungen sind gebäudespezifische Heizkostenabrechnungen von knapp 300 000 Zwei- und Mehrparteienhäusern (über 2 Millionen Wohnungen), klimabezogene Gewichtungsfaktoren ...

Zukünftige Altersarmut und Rentenreformen

In diesem Bericht werden verschiedene Reform- und Arbeitsmarktszenarien hinsichtlich ihrer Wirkung auf die Altersarmut im Zeitraum bis zum Jahr 2045 analysiert. Dabei handelt es sich um Änderungen der Untergrenze für das Sicherungsniveau in der GRV (Haltelinien), der Rentenanpassungsregel, ein höheres Renteneintrittsalter, eine großzügige Freibetragsregelung für Renteneinkommen aus der GRV bei der...

The effect of pension reforms on old age poverty

This project analyses various reform and labour market scenarios with regard to their impact on old-age poverty in the period up to 2045. These are changes to the lower limit for the level of protection in the GRV (holding lines), the pension adjustment rule, a higher retirement age, a generous exemption scheme for pension income from the GRV for basic security, and increased gainful employment at...
