David Hasselhoff’s status as Germany’s favorite American appears safe, from Paul Krugman at least.

Princeton University Prof. Krugman caused a stir in Germany this week with a stinging critique of Bundesbank President Axel Weber, who is considered a frontrunner to succeed Jean-Claude Trichet as head of the European Central Bank when Trichet’s term expires in October 2011.

“If you are looking for someone who is aiming for zero inflation while unemployment is rising to 13%, then Weber is definitely the right guy,” Krugman said in an interview published in German with the business daily Handelsblatt.

“Weber is concerned about inflation, when there is no inflation. I would rather see an ECB President who gives more weight to deflation risks and the risk of a protracted stagnation,” Krugman said, adding that he doesn’t know Weber personally. Before joining the Bundesbank Weber was an economics professor in Germany and fairly well known in U.S. academic circles.

Krugman also criticized Weber’s opposition to the ECB’s purchase of the government bonds of vulnerable countries like Greece and Portugal. The Bundesbank chief touched off controversy in Europe last month when he publicly declared his opposition to buying bonds, breaking a longstanding ECB taboo against airing disagreements in public.

Krugman seems only to have bolstered Weber’s clout among Germans, who wear their anti-inflation obsession as a badge of honor. Germans often say that whereas the Great Depression dominates U.S. economic thinking, Germany’s experience with hyperinflation in the 1920s is its defining economic period of the 20th century, and one that must be avoided at all costs, even if it means slower economic growth.

Dennis Snower, who heads the Kiel Institute for the World Economy, defended Weber, telling Handelsblatt: “He has all it takes to be a fantastic president. He has great sense of responsibility, a strong knowledge base and he knows how important it is to keep inflation expectations stable.”

Krugman didn’t stop with Weber. He has taken on Germany’s plans to rein in its budget deficit, which is already considerably smaller than the U.S.’s as a share of GDP. “German austerity will worsen the crisis in the euro area, making it that much harder for Spain and other troubled economies to recover,” he wrote in his New York Times column.

German politicians, he wrote, “seem determined to prove their strength by imposing suffering — and politicians around the world are following their lead.”

Krugman also told Handelsblatt he wouldn’t rule out sanctions against Germany if it continued to rely on its export-driven model. “If the euro falls to parity with the dollar, the Europeans are going to be surprised by the demands that will come out of the U.S. Congress, and I would support that,” he said.

That fiscal and economic policy critique probably won’t gain any more traction in Germany than his monetary policy one. Germans see their government finances and trade competitiveness as an example to be followed by Greece, Portugal and other troubled countries in Europe. And they clearly don’t see the U.S. model as one worth chasing.

Wolfgang Franz, who heads the German government’s economic advisory panel known as the Wise Men, tore into Krugman — and the US — in an op-ed in the German business daily Wednesday, titled “How about some facts, Mr. Krugman?”

“Where did the financial crisis begin? Which central bank conducted monetary policy that was too loose? Which country went down the wrong path of social policy by encouraging low income households to take on mortgage loans that they can never pay back? Who in the year 2000 weakened regulations limiting investment bank leverage ratios, let Lehman Brothers collapse in 2008 and thereby tipped world financial markets into chaos?” he wrote.

So if Krugman really wants to keep Weber from the ECB presidency, or at least cool some of his support in Germany, he might want to consider damning the Bundesbank chief with praise instead.
