Eurobonds have returned to the forefront of the euro debate. There are many varieties of eurobonds. Some have been designed to mitigate the moral hazard risks that concern German officials (and many others). The euro-nomics group (of which I am a member) have been advocating the concept of “European Safe Bonds” (ESBies) that does not involve joint and several liability, while other proposals have also been made.
Shahin Vallee recently made a presentation to the European Parliament comparing the main alternatives – the presentation file is here.
