Fact Boxes that Inform Individual Decisions May Contribute to a More Positive Evaluation of COVID-19 Vaccinations at the Population Level

ObjectiveFor an effective control of the SARS-CoV-2 pandemic with vaccines, most people in a population need to be vaccinated. It is thus important to know how to inform the public with reference to individual preferences–while also acknowledging the societal preference to encourage vaccinations. According to the health care standard of informed decision-making, a comparison of the benefits and harms ...

Carbon Contracts-for-difference: How to De-risk Innovative Investments for a Low-carbon Industry?

The shift to climate neutrality requires new process technologies for energy-intensive industries, such as steel, chemicals, or cement. A variety of technology options exist – but they face the challenges of (i) first-of-kind costs, (ii) higher operation and investment costs, and (iii) insufficient and uncertain carbon prices, which partly stem from political uncertainty. Existing innovation policy ...

The Assessment of Substitution through Event Studies: An Application to Supply-Side Substitution in Berlin’s Rental Market

The Expansion of Natural Gas Infrastructure Puts Energy Transitions at Risk

Whether additional natural gas infrastructure is needed or would be detrimental to achieving climate protection goals is currently highly controversial. Here we combine five perspectives to argue why expansion of the natural gas infrastructure hinders a renewable energy future and is no bridge technology. We highlight that natural gas is a fossil fuel with a significantly underestimated climate impact ...

Overcoming the Disconnect between Energy System and Climate Modeling

Do Words Hurt More than Actions? The Impact of Trade Tensions on Financial Markets

We use machine learning techniques to quantify trade tensions between the United States and China. Our measure matches well-known events in the US-China trade dispute and is exogenous to the developments on global financial markets. Local projections show that rising trade tensions leave US markets largely unaffected, except for firms that are more exposed to China, while negatively impacting stock ...

Centre-Based Care and Parenting Activities

We examine the relationship between parenting activities and centre-based care using time diary and survey data for mothers in Germany. While mothers using centre-based care spend significantly less time in the presence of their child, we find that differences in the time spent on specific activities such as reading, talking, and playing with the child are relatively small or zero. The pattern of results ...

Does Green Public Procurement Trigger Environmental Innovations?

Green public procurement has gained high political priority and is argued to be an effective demand-side policy to trigger environmental innovations. However, the empirical evidence on its innovation impact is limited. We construct a novel firm-level dataset to investigate the effect of winning public procurement tenders with additional environmental award criteria on firms’ introduction of environmental ...
