The Impact of Public Procurement on Financial Barriers to General and Green Innovation

This study investigates whether public procurement mitigates or exacerbates innovative enterprises’ financial constraints. We distinguish between general and environmentally beneficial innovative enterprises. Theory suggests that the treatment effects of public procurement, particularly when mediated by the demand-pull effect, may lower a company’s funding constraints for innovation. We test this theory ...

The Effectiveness of FX Interventions: A Meta-Analysis

There is ample empirical literature centering on the effectiveness of foreign exchange intervention (FXI). Given the mix of objectives and country-heterogeneity, the general lack of consensus thus far is no surprise. We shed light on this debate by conducting the first comprehensive meta-analysis in the FXI literature, with 279 reported effects that stem from 74 distinct empirical studies. We cover ...

Infection Rates Matter – Especially for People from Lower Social Class: A Large-Scale Investigation of the Impact of the COVID-19 Pandemic on Mental Health

The COVID-19 pandemic was a long-lasting and stressful event that had enormous psychological, economic, and social consequences. This study extends prior research by examining the relationship between infection rates and mental health as well as its dependency on social class. Therefore, we used large-scale data from a nationwide sample (N = 5,742) across two time periods in the COVID-19 pandemic in ...

Gravity Models for Potential Spatial Healthcare Access Measurement: a Systematic Methodological Review

Background Quantifying spatial access to care—the interplay of accessibility and availability—is vital for healthcare planning and understanding implications of services (mal-)distribution. A plethora of methods aims to measure potential spatial access to healthcare services. The current study conducts a systematic review to identify and assess gravity model-type methods for spatial healthcare access ...

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 ...

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 ...

Cohort Profile: Genetic Data in the German Socio-Economic Panel Innovation Sample (SOEP-G)

The German Socio-Economic Panel (SOEP) serves a global research community by providing representative annual longitudinal data of respondents living in private households in Germany. The dataset offers a valuable life course panorama, encompassing living conditions, socioeconomic status, familial connections, personality traits, values, preferences, health, and well-being. To amplify research opportunities ...

Why Investing in New Nuclear Plants Is Bad for the Climate: Commentary

New Coal Mines in the Australian Galilee Basin Are Not Economically Viable and Are Prone to Become Stranded Assets

To limit the effects of climate change, we must significantly curtail the trading and use of coal as an energy source. Although the rise of renewable energy sources has already led to a reduction in the demand for and use of coal, new export-oriented coal mine projects are still being approved, and they often receive strong political support. However, whether these projects are economically viable ...

Geographical Balancing of Wind Power Decreases Storage Needs in a 100% Renewable European Power Sector

To reduce greenhouse gas emissions, many countries plan to massively expand wind power and solar photovoltaic capacities. These variable renewable energy sources require additional flexibility in the power sector. Both geographical balancing enabled by interconnection and electricity storage can provide such flexibility. In a 100% renewable energy scenario of twelve central European countries, we investigate ...
