About the New Deal’s long-run achievements: the institutions F.D.R. built have proved both durable and essential. Indeed, those institutions remain the bedrock of our nation’s economic stability. Imagine how much worse the financial crisis would be if the New Deal hadn’t insured most bank deposits. Imagine how insecure older Americans would feel right now if Republicans had managed to dismantle Social Security.

That said, F.D.R. did not, in fact, manage to engineer a full economic recovery during his first two terms. This failure is often cited as evidence against Keynesian economics, which says that increased public spending can get a stalled economy moving. But the definitive study of fiscal policy in the ’30s, by the M.I.T. economist E. Cary Brown, reached a very different conclusion: fiscal stimulus was unsuccessful “not because it does not work, but because it was not tried.”
This may seem hard to believe. The New Deal famously placed millions of Americans on the public payroll via the Works Progress Administration and the Civilian Conservation Corps. To this day we drive on W.P.A.-built roads and send our children to W.P.A.-built schools. Didn’t all these public works amount to a major fiscal stimulus?
Well, it wasn’t as major as you might think. The effects of federal public works spending were largely offset by other factors, notably a large tax increase, enacted by Herbert Hoover, whose full effects weren’t felt until his successor took office. Also, expansionary policy at the federal level was undercut by spending cuts and tax increases at the state and local level.
And F.D.R. wasn’t just reluctant to pursue an all-out fiscal expansion — he was eager to return to conservative budget principles. That eagerness almost destroyed his legacy. After winning a smashing election victory in 1936, the Roosevelt administration cut spending and raised taxes, precipitating an economic relapse that drove the unemployment rate back into double digits and led to a major defeat in the 1938 midterm elections.
What saved the economy, and the New Deal, was the enormous public works project known as World War II, which finally provided a fiscal stimulus adequate to the economy’s needs.

The economic lesson is the importance of doing enough. F.D.R. thought he was being prudent by reining in his spending plans; in reality, he was taking big risks with the economy and with his legacy. My advice to the Obama people is to figure out how much help they think the economy needs, then add 50 percent. It’s much better, in a depressed economy, to err on the side of too much stimulus than on the side of too little.
In short, Mr. Obama’s chances of leading a new New Deal depend largely on whether his short-run economic plans are sufficiently bold. Progressives can only hope that he has the necessary audacity.
