Inventors‘ Personal Experience of Natural Disasters and Green Innovation

We show that inventors' personal experiences of natural disasters lead to increased green innovation through changes in their higher-order beliefs about consumer preferences. We match patent records of French and German inventors and a survey of inventive firms to detailed information on natural disasters. This allows us to exploit exogenous variation in inventors’ exposure to natural disasters....

Trump’s tariffs: What escalating trade tensions with the US imply for EU exporters and supply chains

US trade policy has taken a sharp turn away from multilateralism, with sweeping new tariffs posing a serious threat to global supply chains.

Trade Barriers and Market Power: Evidence from Argentina’s Discretionary Import Restrictions

Companies may have financial incentives to steer users toward search results or products in a conversation in ways that are unnoticeable...

The Impact of Governmental Regulations on Housing Market: Findings of a Meta-Study of Empirical Literature

Is Russian Gas Still Needed in the European Union? Model-Based Analysis of Long-Term Scenarios

Aligned with the war in Ukraine, Russia has significantly withheld natural gas exports to Europe since 2021. As there are no EU-wide sanctions on imports of Russian natural gas, the Ukraine transit as well as imports via Turkey and LNG have remained active during 2022–24. However, the Russian-Ukrainian transit agreement expires at the end of 2024 and discussions about new sanctions on natural gas as ...
