How Divestitures Affect Bargaining Power

This paper studies how bargaining power is affected by merger and divestiture policies. I provide a new empirical framework to compute bounds on brand-level bargaining weights using widely available sales data. Next, I exploit the variation in brand ownership caused by a large merger, cleared conditional on divestiture, in the U.S. deodorant market, to quantify the extent to which divestitures...

What is the Right Geographic Market Definition?

What is the “right” geographic definition of relevant markets? We study how unexpected and exogenous increases in excise duties in petroleum products were passed-through to retail prices in the Athens region and examine how the degree of the pass-through varies across different geographic relevant markets. Using various definitions of the relevant geographic market, we find that the most...

When Competition is not Desired: the Case of Antibiotic Prescribing

Antibiotics are effective in treating bacterial infections. However, the excessive usage of antibiotics leads to the development of antibiotic resistant bacteria, which significantly reduces their effectiveness. Current strategies to address antibiotic resistance mainly target primary care physicians, who serve as the gatekeepers of antibiotic prescriptions in many countries. Therefore, it is...

Government Ownership and Competition: Evidence from the European Airline Industry

This paper empirically analyses the impact of government ownership on competition in monopoly and duopoly markets. We use the European Airline Industry as a laboratory. In our empirical strategy we exploit two sources of exogenous variations that allow us to cleanly filter out the effect of government ownership on the likelihood of exit. First, we study government ownership that was triggered by a...

Free Allocation and Exports

The European Emissions Trading System (EU-ETS) is the key policy tool of the EU to reduce GHG emissions. To prevent carbon leakage, most of the emission permits have been allocated for free in the industrial sector. A carbon border adjustment mechanism (CBAM) will be introduced end of 2023 as an alternative carbon leakage protection instrument. However, the CBAM will only gradually replace free...

Competition and VAT Pass-Through

We examine how competition affects VAT pass-through in isolated oligopolistic markets as defined by the Greek islands. Using daily gasoline prices and a difference-in-differences methodology, we study how changes in VAT rates are passed through to consumers in islands with different number of retailers. We show that pass-through increases with competition, going from 50% in monopoly to around 80%...

Are M&As Spurring or Stifling Innovation? - Evidence from Antidiabetic Drug Development

The innovation impact of acquisitions of small targets with products close to launch by large product market incumbents is currently debated, weighing whether incumbents might preemptively terminate or “kill” the innovative projects of these targets. This paper provides empirical evidence on which M&A deals spur and which stifle innovation. To this end, we not only look at the product market...
