Increased business capital expenditures, or “capex,” remain one of the most important pieces for improving the long-term growth trajectory of the U.S. economy. Capital expenditures help increase productivity, and improved productivity is the foundation for sustainable higher growth for developed economies. Both survey and hard data continue to confirm that we might be seeing a rebound in capex, but how can we know it’s sustainable? The answer may be in our beach reading. Like the veteran detective in a favorite page-turner, we look for means, motive, and opportunity. For capex spending, means translates to additional sources of funding for projects, motive comes from increased business confidence and tight labor markets, and opportunity from fiscal incentives and global growth.
