WARSAW  With its drab, Soviet-era boulevards and standard-issue glass-and-steel office buildings, Warsaw does not look much like green, elegant Dublin. But there are some striking similarities between Poland today and Ireland in the 1990s.

Like the Irish a couple of decades ago, the Poles are a hardy people battered by history but on the verge of prosperity. Foreign capital is pouring in and investment banks are opening offices, lured by resilient growth and 38.5 million people who are close to shedding the “emerging market” label.

And Poland now, like Ireland then, has its own currency. Being outside the euro zone is working to Poland’s economic advantage.

That is not the only reason Poland is currently that rare species: a financially vibrant member of the European Union. But it is to Poland’s benefit not to be bound by a common currency, at a time when euro zone countries like Ireland will have trouble using cheap exports to grow their way out of trouble.
