As the US unemployment rate has risen to 9.5 per cent from 8.1 per cent since the $787bn fiscal stimulus package was enacted in February, many Democrats have become very nervous. They say that another large stimulus may be needed to keep unemployment from rising well beyond the 10 per cent rate that President Barack Obama has predicted will be reached this year.

Another stimulus would be a grave mistake. The first one was justified by extraordinary circumstances. But it must be given time to work. People should not allow their impatience to lead to the adoption of policies that will not only fail to reduce unemployment this year, but could stoke inflation in the not-too-distant future.
