More Europe: 13 challenges—13 solutions for more convergence, stability, and competition

Around 20 DIW Berlin economists present solutions to European challenges - Uniform conditions can make the EU more resilient - Better incentive systems ensure more convergence - Europe must be united in countering global economic risks such as the US tariff dispute Growth and progress towards equal living conditions across the European Union continues, but the crises of recent years have shown that ...

Increased Instruction Time and Stress-Related Health Problems among School Children

While several studies suggest that stress-related mental health problems among school children are related to specific elements of schooling, empirical evidence on this causal relationship is scarce. We examine a German schooling reform that increased weekly instruction time and study its effects on stress-related outpatient diagnoses from the universe of health claims data of the German Social Health ...

Using the Dirichlet Process to Form Clusters of People’s Concerns in the Context of Future Party Identification

Connections between interindividual differences and people’s behavior has been widely researched in various contexts, often by using top-down group comparisons to explain interindividual differences. In contrast, in this study, we apply a bottom-up approach in which we identify meaningful clusters in people’s concerns about various areas of life (e.g., their own health, their financial situation, the ...

Flexible Electricity Generation, Grid Exchange and Storage for the Transition to a 100% Renewable Energy System in Europe

Two transition pathways towards a 100% renewable energy (RE) power sector by 2050 are simulated for Europe using the LUT Energy System Transition model. The first is a Regions scenario, whereby regions are modelled independently, and the second is an Area scenario, which has transmission interconnections between regions. Modelling is performed in hourly resolution for 5-year time intervals, from 2015 ...

EU Merger Policy Predictability Using Random Forests

I study the predictability of the EC’s merger decision procedure before and after the 2004 merger policy reform based on a dataset covering all affected markets of mergers with an official decision documented by DG Comp between 1990 and 2014. Using the highly flexible, non-parametric random forest algorithm to predict DG Comp’s assessment of competitive concerns in markets affected by a merger, I find ...

The Peer Composition of Pre-School Settings in England and Early Recorded Attainment among Low-Income Children

Evidence suggests that early education can promote children’s development and narrow attainment gaps between those from lower-income and higher-income families. However, realisation of these potential benefits depends on many factors, feasibly including peer composition. We use national census data for a year-group cohort of children in England in 2011, to answer two questions: how are low-income children ...

Simulating the Potential of Swarm Grids for Pre-Electrified Communities: A Case Study from Yemen

Swarm grids are an emerging approach to electrification in the Global South that interconnects individual household generation and storage to a small electricity network to make full use of existing generation capacities. Using a simulation tool for demand, weather, and power flows, we analyse the potential of an AC swarm grid for a large pre-electrified village in rural Yemen. Service quality and ...
