BERLIN — Throughout the crisis in the euro zone, as governments have fallen, debt burdens have mounted and economies have stagnated or shrunk, Germany has floated above the fray. While its economy has hummed along nicely, its leaders have steadfastly insisted that the path to redemption for the debtors lies in austerity and suffering.

When Chancellor Angela Merkel on Monday described the debt crisis as Europe’s “most difficult hours since World War II,” she was describing something most Germans had only read about in newspapers or watched on television. The German economy once again surprised experts on Tuesday, growing an unexpectedly healthy 0.5 percent in the third quarter and 2.5 percent higher than the year before.

While there were ominous signs that Europe’s slowdown would also strike Germany, its biggest economy — particularly worrisome was a sharp drop in industrial production in September — the pain that euro zone partners have been feeling has yet to arrive here.

With German consumers spending freely, unemployment has reached the lowest level since German reunification more than two decades ago, and it continued falling in October. Tax receipts consistently beat government projections, to the point that Mrs. Merkel’s coalition even has plans to cut taxes by more than $8 billion.
