Green shoots are bursting out. Or so we are told. But before concluding that the recession will soon be over, we must ask what history tells us. It is among the guides we have to our present predicament. Fortunately, we do have the data. Unfortunately, the story they tell is an unhappy one.

Two economic historians, Barry Eichengreen of the University of California at Berkeley and Kevin O'Rourke of Trinity College, Dublin, have provided pictures worth more than a thousand words (see charts).* In their paper, Profs Eichengreen and O'Rourke date the beginning of the current global recession to April 2008 and that of the Great Depression to June 1929. So what are their conclusions on where we are a little over a year into the recession? The bad news is that this recession fully matches the early part of the Great Depression. The good news is that the worst can still be averted.
