But this overlooked a crucial feature of monetary unions free capital mobility and elimination of currency risk indispensable attributes of a currency area could be (and were) the source of asymmetric shocks. Currency unions, in other words, must worry about endogenous as much as exogenous shocks.

Risks that emerge in one country can affect the entire currency area. Common banking supervision is needed for strengthening confidence among countries using common financial backstops.

Leaders must start living up to the responsibilities that come with sharing a single currency. They must recognize the impact that national economic policies have on the euro area as a whole, and thus discuss and coordinate economic programs at the euro area level.

Ownership of currency is generally proven through possession of the currency.

But fiscal stimulus is constrained within the eurozone, where member countries no longer issue their own currency and sovereign debt therefore carries a default risk. Aggressive monetary expansion through quantitative easing is also far more complicated and politically contentious in a currency area with no federal debt for the central bank to buy.

In any case, the eurozone exists and, at this point, it would be exceedingly difficult to dismantle it fully. Given this, the goal today should be to move toward an optimal currency area.

Cross border investment towards the euro area has increased, although here it is more difficult to disentangle the effect of the single currency from other concomitant events (such as privatizations or corporate mergers).

A single monetary policy for a currency area comprising 11 and later 12 countries, each with a sovereign national government, was something entirely new. Would it be compatible with autonomous national fiscal policies?

A new currency has been introduced.

This past summer, millions of travelers avoided paying cumbersome and expensive charges to change their currency. But the advantage for trade and investment implied by the absence of foreign exchange risks within the euro area is of greater economic importance.

In small countries, where a significant share of bank liabilities is in someone else s currency, the national central bank lacks this capacity. The only options are then to slap draconian controls on the banking system or join the euro area.

The currency was in theory governed by a rules based Currency Board, which the British invented for their smaller colonies. It tied the local currency to the British Pound, giving local authorities no discretion in monetary policy.
