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.
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...
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...
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...
This paper examines how firms' CO2 emission intensity (CEI) responds to trade shocks. Changes in market conditions, such as trade shocks, are believed to drive specialization toward core products, foster innovation, improve productivity, and influence abatement choices. I develop a unified framework that decomposes within-firm changes in CEI into within- and between-product components and...
We discuss with experts from academia, politics and industry how the Carbon Border Adjustment Mechanism (CBAM) for sectors with complex value chains can be further developed or reformed in order to create reliable investment framework for climate-neutral raw material production while effectively limiting carbon leakage risks. In particular, we discussed an EU ETS and CBAM reform for materials...
In this article, we introduce the command beyondpareto, which estimates the extreme-value index for distributions that are Pareto-like, that is, whose upper tails are regularly varying and eventually become Pareto. The estimation is based on rank-size regressions, and the threshold value for the upper-order statistics included in the final regression is determined optimally by minimizing the asymptotic ...
