It is commonly found that the markets for long-term government bonds of Economic and Monetary Union (EMU) countries were integrated prior to the EMU debt crisis.

Has the Euro created a more competitive market? Using a staggered difference-in-differences design we find that the Euro has increased firm-level market power between 23% and 30% after its adoption. This happens because deepening economic integration creates a stronger competitive environment...

Under the Single Supervisory Mechanism (SSM), introduced in 2014, systemically important euro area banks with combined assets of about 21,000 billion euros are directly supervised by the ECB. We examine from a static and a dynamic perspective how this fundamental shift to unified supervision...
