Alberto Alesina of Harvard has surveyed the history of debt reduction. He’s found that, in many cases, large and decisive deficit reduction policies were followed by increases in growth, not recessions. Countries that reduced debt viewed the future with more confidence. The political leaders who ordered the painful cuts were often returned to office. As Alesina put it in a recent paper, “in several episodes, spending cuts adopted to reduce deficits have been associated with economic expansions rather than recessions.”
This was true in Europe and the U.S. in the 1990s, and in many other cases before. In a separate study, Italian economists Francesco Giavazzi and Marco Pagano looked at the way Ireland and Denmark sharply cut debt in the 1980s. Once again, lower deficits led to higher growth.
"During the period of consolidation, in other words, the government will have to spend less, but target better. That will require enormous dexterity and intelligence from a political system that has recently shown neither."
