A little while ago, Vice President Joe Biden had the audacity to say,   “Every economist, as I’ve said, from conservative to liberal, acknowledges that direct government spending on a direct program now is the best way to infuse economic growth and create jobs.

Well, the McClatchy wire carried this headline today: “Will the stimulus actually stimulate? Economists say no.” From the story:

“I think (doing) nothing would have been better,” said Ed Yardeni, an investment analyst who’s usually an optimist, in an interview with McClatchy. He argued that the plan fails to provide the right incentives to spur spending.

Another reason that some analysts frown on the stimulus is the social spending it includes on things such as the Head Start program for disadvantaged children and aid to NASA for climate-change research. Both may be worthy efforts, but they aren’t aimed at delivering short-term boosts to economic activity.

Even some proponents of a stimulus are disappointed, however. Harvard University economist Martin Feldstein, a former adviser to President Ronald Reagan, was an early supporter. He said that government is now the only engine left to spark economic activity, but he said that the compromise falls short of what’s needed.

“If the choice is between the current bill and an improved bill, I would say wait and improve the bill,” Feldstein told CNBC on Wednesday after the compromise was announced. “I am disappointed with the structure of this bill.”

Like Yardeni and other analysts, Feldstein wanted more incentives for consumers to make big purchases that have ripple effects across the economy. When a car is purchased, it helps not only the carmaker, but its suppliers, the trucking companies and railroads that transport cars, the states that issue license plates and so on.
