Capital investment activity at non-corporate businesses has been declining for the past decade, data from the Federal Reserve\u2019s Flow of Funds report shows. Between 2000 and 2011, the latest year data are available, the average non-corporate non-financial business reduced its gross fixed capital formation by one-third, when measured in inflation-adjusted terms. This decline is troubling. Investment in machines, office equipment, vehicles, software, and other fixed assets helps companies to boost their productive capacity. A lower average level of investment means that businesses are investing less in plant and equipment than they used to. Gross fixed capital formation measures the change in the value of fixed assets \u2013 nonresidential equipment, structures, software, research and development and entertainment, literary and artistic originals \u2013 before adjustment for consumption or depreciation of the assets. While the measure isn\u2019t the same as total investment \u2013 it excludes money put into financial assets and land, as well as additions to inventories and other non-fixed assets \u2013 gross fixed capital formation does capture the willingness of businesses to purchase capital goods that are used for productive purposes. The Federal Reserve measures the gross fixed capital formation of non-corporate, non-financial companies separately from that of corporations. Because non-corporate, non-financial businesses include all non-farm entities set up as sole proprietorships or partnerships, it\u2019s a good proxy for small businesses. The figure above\u00a0plots the inflation-adjusted average amount of gross fixed capital formation for non-farm partnerships and sole proprietorships from 1980 to 2010, measured in inflation-adjusted dollars. Two patterns emerge clearly from the data. First, the average amount that non-corporate, non-financial businesses invested in fixed assets trended upward from 1992 to 2000, and then reversed course between 2000 and 2011, with the most precipitous decline occurring during the Great Recession. Second, the average non-financial, non-farm, non-corporate business invests far less in fixed assets now than it did in the 1980s. When measured in inflation-adjusted terms, the amount that the average business invested in gross fixed capital declined from $22,560 per year (in 2010 dollars) in 1980 to $9,390 (in 2010 dollars) in 2011. In short, small businesses are not investing in capital assets to the extent that they once did. That\u2019s not a positive sign for the future productive capacity of the small business sector.
