In an interview on YLE's breakfast TV show, Kanniainen said that, with its own currency, Greece would be able to improve its competitiveness.
According to the professor, history shows that economic growth has often followed the introduction of a country’s own currency.
Kanniainen pointed out that the Greek budget deficit is going to remain around 8 percent this year.
He noted that the country’s new property tax, which is designed to raise two billion euros, will not do much to resolve the debt crisis.
