Digital platforms operate in multisided markets providing services through the internet to two or more distinct groups of users, between which there are indirect network effects. Direct network effects are frequently present within each group. Therefore, online platforms usually present both...

This paper considers the integration of competition policy and innovation policy in the context of R&D cooperation. An explicit comparison of the welfare losses under ex-ante and ex-post R&D cooperation reveals differing incentives to undertake R&D in both regimes. The strength of these...

I develop a model of R&D cooperation with uncertain research outcomes. In this model asymmetric outcomes of R&D competition emerge naturally. Therefore ex-ante and ex-post R&D cooperation can be studied as alternatives for firms. Using this model I compare welfare losses under ex-ante and...

Information asymmetries can severely limit cross-border border expansion of banks. When a bank enters a new market, it has incomplete information about potential new clients. Such asymmetries are reduced by credit registers, which distribute financial data on bank clients. We investigate the...

This paper tests for the existence of market power in banking, using data on demand deposit rates of households and corresponding market rates in five euro area countries. An implicit measure for market power is based on a partial adjustment model that also allows for an asymmetric response of...

We quantify the impact that central bank refinancing operations and funding facilities had at reducing the banking sector’s intrinsic fragility in the euro area in 2014-2019. We do so by constructing, estimating and calibrating a micro-structural model of imperfect competition in the banking...

The present paper explores issues surrounding multilateral interchange fees (MIFs) in payment card markets from various angles. The Eurosystem’s public stance on interchange fees is neutral. However, the Eurosystem takes a keen interest in facilitating a constructive dialogue among the...

The European market has been served by regulated and licensed e-money tokens (EMTs) since 2019, contradicting the claim that legal clarity is needed for EMTs. Despite the well-functioning e-money legislation, the EU Parliament will vote on a new regulation specifically for EMTs as part of the...

Minimum capital requirement regulation forces banks to refund a substantial amount of their investments with equity. This creates a buffer against losses, but also in- creases the cost of funding. If higher refunding costs translate into higher loan interest rates, then borrowers are likely to...
