This paper analyses the dynamics of hotel prices listed on Booking.com in the period 2014-16. This period is characterised by the most important antitrust decisions regarding the use of price parity clauses by online travel agencies (OTAs) in the EU. First, we document the dynamics of hotel...

Online platforms often impose Price Parity Clauses to prevent sellers from charging lower prices on alternative sales channels. We provide quasi-experimental evidence on the full removal of Price Parity Clauses in France in 2015 for hotels listed on Booking.com. Our analysis reveals significant...

This paper empirically assesses the effects of competition in the financial sector on credit procyclicality by estimating both an interacted panel VAR (IPVAR) model using macroeconomic data and a single-equation model with bank-level European banking data. The findings of these two empirical...

This paper empirically investigates the evolution and the sources of interest rate pass-through heterogeneity in the Eurozone for a sample of 11 euro area countries over the period 2003M1-2011M12. Considering two harmonized bank retail rates, we first estimate single equation error correction...

The ministerial proposal for a 10th amendment of the German competition law particularly addresses abuse control and seeks to tighten this pillar of competition policy against the background of the challenges from the digital economy. Next to extending the classic policy instruments of abuse...

The ubiquitous process of digitization changes economic competition on markets in several ways and leads to the emergence of new business models. The increasing roles of digital platforms as well as data-driven markets represent two relevant examples. These developments challenge competition...

Two seemingly unconnected empirical results suggest an intriguing mechanism. First, economic integration helps harmonize prices internationally, with trade being the primary channel (Rogoff 1996, Goldberg and Knetter 1997). Second, monetary union may greatly increase the amount of trade among...
