Long-Term Gains of Graduating in a Recession for Low Educated Entrants

Economic conditions at time of labor market entry have been shown to have large negative effects on labor market outcomes for an extended period of time. The immediate effects have been shown to be worse for lower educated entrants. In the long run, the effects may be very different as low and high educated have different possibilities to accommodate this negative shock, high educated entrants can...

Declining Effective Tax Rates of Multinationals: The Hidden Role of Tax Base Reforms

This paper documents the rise of corporate tax-base narrowing measures in the EU using a novel dataset covering both tax rate and tax base reforms implemented between 2014 and 2022. Our findings indicate a shift away from the ’cut rate – broaden base’ approach, as governments increasingly align corporate taxation with industrial policy objectives. We show that EU tax competition exerts downward pressure ...

Taxonomy Disclosure in the EU: A Useful Framework, Despite Current Challenges

The EU Taxonomy is a classification system for sustainable economic activities and a framework for various regulatory initiatives. Its primary objectives are to enhance transparency, to reduce greenwashing and ultimately to redirect capital toward more sustainable activities. However, since its introduction, market participants have raised concerns about whether the benefits justify the costs. This ...

Contracts in Crisis: The War in Ukraine and Long-Term Contracts in Energy Markets

We examine the impact of the war in Ukraine on long-term contracts in energy markets. We find that traded contract volumes fall by 65 percent in the first months of the war. A collapse in bilateral trading contributes most to this decline. To protect themselves from price shocks, firms increasingly turned to long-term contracts already before the war. In sum, our results show that the market continued ...

Optimal Discounts in Green Public Procurement

We provide an auction-theoretical analysis of Green Public Procurement (GPP) as a preferential program aimed at stimulating investment in green technologies. We find that GPP incentivizes more competitive firms to invest. We also show that GPP can be an optimal mechanism for a procurer who cares about minimizing the purchasing price while triggering green investment.

Public Communication and Collusion: New Screening Tools for Competition Authorities

Competition authorities increasingly rely on economic screening tools to identify markets where firms deviate from competitive norms. Traditional screening methods assume that collusion occurs through secret agreements. However, recent research highlights that firms can use public announcements to coordinate decisions, reducing competition while avoiding detection. We propose a novel approach to...

What is the “Right” Geographic Market Definition?

This paper examines the “right” geographic definition of relevant markets by analysing how excise tax pass-through varies with local competition in the retail gasoline market of Athens, Greece. Using a natural experiment from three unanticipated and exogenous fuel tax hikes in 2010 and detailed station-level price data, we show that average pass-through is almost complete and invariant to the...

On the road to net zero: Enhancing transition risk assessment with bank transition plans?

Bank transition plans (TPs) are becoming vital tools for assessing financial institutions' climate resilience and readiness for a sustainable economy. The EU’s 2024 Capital Requirements Directive 6 mandates that banks develop TPs for prudential oversight, with supervisors required to evaluate them. In response, the European Banking Authority (EBA) has issued guidelines to support banks in...
