Pilot-, test- and demonstration-projects (PTDs) are a prominent tool to promote the diffusion of green technologies by activating the ‘quadruple helix', i.e. a collaboration of industry, academia, government and civil society. However, as technology diffusion is heavily dependent on individual...

Home energy storage (HES) poses a promising option to foster flexible electricity demand and grid-stabilising self-supply. Understanding the characteristics of potential storage adopters and their motives for adopting is essential to enable targeted measures to promote diffusion. This paper...

Starting in 2004/2005, the German state Baden-Wurttemberg reduced academic track duration from nine to eight years, leaving cumulative instruction time mostly unchanged. I use this change in schooling policy to identify the effect of schooling intensity on student well-being in life and school,...

A large literature aims to establish a causal link between education and health using changes in compulsory schooling laws. It is however unclear how well more education is operationalized by marginal increases in school years. We shed a new light on this discussion by analyzing the health...

Are there skill differentials in young children's competence levels by their self-regulation abilities and do such early life differences mark the onset of increasing disparities in competence development? We add to previous research by investigating the relationship between preschoolers'...

Are there differentials in children's competence levels by their self-regulation and do they imply differences in competence development? We investigate the relationship between preschoolers' self-regulation and their mathematical competence and its development using data from the German...
