Title: Interest rates and backward-bending investment
Description: "This paper shows that interest rate reductions do not necessarily stimulate investment in an environment with uncertainty and adjustment costs.  When firms making lumpy investment decisions can acquire information about profitability by delaying, aggregate investment demand is always a backward-bending function of the interest rate.  An interest rate increase is more likely to stimulate investment when the potential to learn is larger and in the short run rather than the long run.  The average observed profit rate is also a backward-bending function of the interest rate when firms learn over time"--National Bureau of Economic Research web site.
