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...

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...

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. As the US remains the EU’s largest export market for goods, these measures carry significant repercussions for the bloc. Exports to the US are heavily reliant on a small number of companies and high-value business relationships—making the EU particularly...

Targeting Viewers’ Heterogeneous Ad Aversion: Evidence from a Two-Sided Market

This paper studies the role of viewers’ heterogeneous ad aversion on media content demand and advertisers’ willingness to pay. High-frequency individual-level data on broadcast media content allows us to track viewers’ minute-by-minute choices within the set of available alternatives. We first illustrate the potential selection biases that arise when using aggregated market-level data to estimate...

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

Countries are increasingly turning to non-tariff barriers that are hard to measure and often illegal under WTO rules. What are the impacts of these policies, and what do they reveal about market power in international trade? We study a comprehensive system of discretionary import licenses imposed by Argentina, where we observe the universe of transaction-level requests and approval decisions...

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

Housing markets are affected by a large variety of factors. Among them, governmental regulations play an important role. Besides desired effects, all these policies exert a number of side effects, some of which can even offset the desired effects. In addition, different policies can cancel out each other. Therefore, it is important to be aware of the effects of individual policies and the composite ...
