Common ownership - when an investor holds shares in two or more companies - has recently attracted significant attention from policy-makers and researchers, studying mainly US firms. European firms, however, are different as top investors with large stakes, like governments, founding families and foundations are much more prevalent. This paper takes a well-known common ownership with micro-economic ...

The transition to low-carbon economies requires massive investments into renewable energies, which are commonly supported through regulatory frameworks. Yet, governments can have incentives – and the ability – to deviate from previously announced support policies once those investments have been made, which can deter investments. We analyze a renewable energy dynamic regulation game and derive under ...

We use the prolonged Greek crisis as a case study to understand how a lasting economic shock affects the innovation strategies of firms in economies with moderate innovation activities. Adopting the 3-stage CDM model, we explore the link between R&D, innovation, and productivity for different size groups of Greek manufacturing firms during the prolonged crisis. At the first stage, we find that the ...

DIW Weekly Report 32/33/34 / 2022
According to Socio-Economic Panel (SOEP) data, inequality in gross monthly earnings in Germany increased significantly between 1993 and 2003 and has been stagnating at a high level since 2008. As this Weekly Report shows, the increase is not being driven by higher hourly wage inequality, but rather by working hours: In recent years, employees with a high hourly wage work more than previously compared ...

DIW Discussion Papers 2014 / 2022
The purpose of this study is to identify whether an innovative company’s likelihood of facing financial constraints is different when the company possesses a public procurement contract (PP). 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 and apply extended ...

In this article, we provide the results of a simple quantitative analysis of the potential remedies to reduce the supply gap in Germany that arises if Russia stops delivering natural gas. We take into account the supply potential of other suppliers, and combine this with an analysis of the additional supply potential by stopping electricity generation from natural gas. Moreover, we investigate the ...

The use of green hydrogen can support the decarbonization of sectors which are difficult to electrify, such as industry or heavy transport. Yet, the wider power sector effects of providing green hydrogen are not well understood so far. We use an open-source electricity sector model to investigate potential power sector interactions of three alternative supply chains for green hydrogen in Germany in ...

The current governance process to plan the German energy system omits two options to substitute grid expansion: First, placing renewables closer to demand instead of where site conditions are best. Second, utilizing storage instead of additional transmission infrastructure to prevent grid congestion. In the paper, we apply a comprehensive capacity expansion model based on the AnyMOD modeling framework ...

The COVID-19 pandemic and related closures of day care centres and schools significantly increased the amount of care work done by parents. There has been much speculation over whether the pandemic increased or decreased gender equality in parental care work. Based on representative data for Germany from spring 2020 and winter 2021 we present an empirical analysis that shows that although gender inequality ...
