Deregulatory moves, both actual and anticipated, have been hailed as spurring business fixed investment. Is there content to this assertion? A glance at nonresidential fixed investment seems to be supportive.

However, the standard investment series reported in the NIPA tables pertain to gross investment spending, i.e., not taking into account depreciation. As capital expenditures have skewed more toward information and communication technology (ICT) equipment and software, the pace of capital depreciation has accelerated. As a consequence, the net and gross series have deviated more profoundly over time. Plotting net investment and gross investment (on a log scale) provides a fairly surprising picture.

The figure makes clear, despite the recent acceleration in investment, net investment has not re-attained levels achieved in 2014Q3 (let alone on the eve of the last recession).
Moreover, because GDP has grown over time, the (log) ratio of investment to GDP has declined. The same is true for log(I/K). [Note: I don’t show I/K or I/GDP because all series expressed in Chained dollars, and ratios of such are not meaningful.)
