The great economist and bon vivant, Joseph Schumpeter, described the failure of low interest rates to stimulate the animal spirits of businessmen as “PUSHING ON A STRING.” In paraphrasing this concept, high interest rates can stop an entrepreneur from borrowing but ultra-low rates cannot stimulate investment if there is no expected return higher than the cost of capital. Some pundits continue to insist that banks aren’t lending while many of the banks insist that there is no business or consumer demand. It is driving the Bernanke FED crazy that with interest rates at zero, capital investment is just not reaching levels high enough to add jobs.
