Parallel currency not the solution for Greece: Capital Economics

Quotes from  Capital Economics:

- The idea that Greece could introduce a parallel domestic currency to improve its competitiveness while still honouring its international debts is not the solution to the country's problems. 

- The introduction of a parallel currency would carry many of the costs of leaving the eurozone altogether, but potentially lack some of the key benefits. 

- If it happened, it would be more about saving face than anything else and would almost certainly be a stepping stone to an exit rather than an alternative to it.
