In 2022, Germany introduced a temporary 9-euro monthly ticket for unlimited local and regional public transport. We investigate its impact on mobility patterns, including increased public transport usage, reduced car traffic, and rail network congestion. Using difference-in-difference and...

Pricing greenhouse gases is widely understood as the most efficient approach for mitigating climate change, yet distributional effects hamper political acceptance. These distributional effects are especially important in transport, the fastest growing sector for greenhouse gas emissions. Using...

A national-champions-related industrial policy has become (again) en vogue among European politicians. Against this background, our work orders different types of national champions along the industry lifecycle. Different types of locally bound externalities appear along the lifecycle. In a...

Abatement can be performed by measures that have an impact on present emissions, but no lasting effect, and by long-lived infrastructure investments. We study the optimal combination of short and long-lived options for reducing greenhouse gas (GHG) emissions, by specifying abatement cost...

When regulated firms are offered compensation to prevent them from relocating, efficiency requires that payments be distributed across firms so as to equalize marginal relocation probabilities, weighted by the damage caused by relocation. We formalize this fundamental economic logic and apply it...

We evaluate the impact of a major European state aid programme for broadband deployment applied to rural areas in the German state of Bavaria in the years 2010 and 2011. Using matched difference-in-differences estimation strategies, we find that aided municipalities have - depending on broadband...

We quantify general equilibrium effects of place-based policies in a multi-region framework with mobility, trade and agglomeration economies. Using detailed data on EU transfers, we infer the local effects of different transfer types on productivity, income and transportation cost. Based on...

In this paper we employ survey information on more than 10,000 Southern and Eastern European firms and panel data methods to assess the effects of the COVID-19-related lockdown and government support policies on the business operations of enterprises. Our findings reveal considerable size- and...
