Today there is depressing news on business confidence. It is, according to one survey, at a twenty year low.
Business confidence is by far the most important determinant of investment. It outweighs the influence of interest rates significantly.
If the outlook of firms improves and they start to expect better business prospects they will invest. If the invest then Aggregate Demand will rise and probably by a multiplied amount. And so the recovery will be formed.
But the survey says that business confidence is falling not improving. And so the dreaded double dip continues.
