“The question was always, ‘Would the economy hang on by its fingernails?’ ” said Ethan Harris, the chief United States economist at Lehman Brothers. Based on the employment report, Mr. Harris said, “there’s a very high probability that we’re in a recession now.”  Even the one apparent piece of good news in the employment report was a mirage. The unemployment rate fell to 4.8 percent, from 4.9 percent in January, but only because more people stopped looking for work and thus were not counted as unemployed by the government.  Over the last year, the number of officially unemployed has risen by 500,000, while the number of people outside the labor force — neither working nor looking for a job — has risen by 1.3 million.  Employment has risen by 100,000, but even that comes with a caveat: there are also 600,000 more people who are working part time because they could not find full-time work, according to the Labor Department.  “The decline in the unemployment rate,” said Joshua Shapiro, an economist at MFR, a research firm in New York, “should not be viewed as good news.”  Much of the economic stimulus put in place by the government will begin to take effect in the next few months, which does leave open the possibility that the country can still escape a recession. Policy makers have reacted quite quickly to this slowdown, relative to previous ones.  The Treasury Department will begin sending out rebate checks — of up to $1,200 for couples, plus $300 per child — in May, as part of the stimulus package negotiated by President Bush and Democratic leaders in Congress. The Fed has already cut its benchmark short-term interest rate five times since September, and such reductions typically take six months or more to wash through the economy.  White House officials have predicted in recent weeks that the economy would avoid recession, but after the release of the jobs report, they offered a subtly different forecast. At the White House on Friday, Edward P. Lazear, the chairman of Mr. Bush’s Council of Economic Advisers, parried reporters’ questions about whether he now thought the economy would slip into a recession.  Instead, he said, “I’m still not saying that there is a recession.”  The administration does expect growth in the current quarter to be slower than it had previously thought, before accelerating this summer. “Obviously, we are concerned,” Mr. Lazear said. But he added that he remained hopeful that “growth will pick up, and pick up quickly.”  The most commonly cited arbiter of recessions is the National Bureau of Economic Research, a group of academic economists that is based in Cambridge, Mass. (Mr. Lazear referred to the group at his briefing, saying it would not be clear whether there had been a recession until the bureau had made an announcement.)  The seven economists who sit on the bureau’s recession-dating committee began exchanging e-mail messages late last year about whether the economy was on the verge of a recession. But committee members said Friday that it remained too early to know.  The bureau defines a recession as a significant, protracted decline in activity that cuts across the economy, affecting measures like income, employment, retail sales and industrial production.  “Given that definition, the committee can’t possibly call a recession until it has been going on for a while,” said Christina D. Romer, an economics professor at the University of California, Berkeley. “There is no way to know if the downturn will be sufficiently long-lasting until it has lasted for a while.”  The committee did not announce the end of the last recession — which came in November 2001 — until more than a year-and a half later. Robert J. Gordon, a Northwestern University economist on the committee, said any announcement about the start of a new recession was unlikely before the last few months of 2008 at the earliest.  Recent recessions have inevitably brought inflation-adjusted income declines for most families, which would be particularly painful given what has happened over the last decade. For a variety of reasons that economists only partly understand — including technological change and global trade — many workers have received only modest raises in recent years, despite healthy economic growth.  The median household earned $48,201 in 2006, down from $49,244 in 1999, according to the Census Bureau. It now looks as if a full decade may pass before most Americans receive a raise.

If history is a reliable guide, a dismal jobs report suggests that the recession of 2008 is now unavoidable.
