Nonresidential fixed investment grew 2.1 percent in the first quarter of this year, with 3 percent growth in equipment and software investments partially offset by a 0.3 percent decrease in investment in structures, according to the April 26 report by the Commerce Department on gross domestic product (GDP) and an analysis by the Associated Builders and Contractors (ABC).

In contrast, residential fixed investment increased 12.6 percent in the first quarter of 2013, following a 17.6 percent jump in the fourth quarter of 2012, according to the report.

Personal consumption expenditures advanced 3.2 percent in the first quarter with spending on goods increasing 3.3 percent and spending on services increasing 3.1 percent. The growth in real private inventories added 1 percentage point to GDP growth for the quarter after subtracting 1.5 percent from the fourth quarter.

Federal government spending fell 8.4 percent in the first quarter with national defense spending dipping 11.5 percent and nondefense spending slipping 2 percent. State and local government spending decreased 1.2 percent for the quarter following a 1.5 percent decrease in the prior quarter.

Real final sales of domestically produced output—minus changes in private inventories—increased 1.5 percent for the quarter following a revised 1.9 percent increase during the fourth quarter. Gross domestic purchases—purchases by U.S. residents of goods and services wherever produced—increased 2.9 percent in first quarter after going unchanged in the fourth quarter.

Overall, the nation’s GDP grew at an annual rate of 2.5 percent in the first quarter of 2013; far short of the 3 percent economists were predicting, but higher than the 0.4 percent posted in the fourth quarter of 2012.

“Today’s GDP report is evidence that the nation’s economic growth continues to be disproportionately motivated by consumer purchases,” says ABC chief economist Anirban Basu. “To the extent that businesses are participating, much of the buying momentum is not related to construction, but is more closely related to equipment and software purchases.

“Investment in nonresidential structures actually declined in the quarter, a reflection of the fact that the nation’s recovery, to date, has been unable to support a sustained nonresidential construction recovery,” adds Basu.

He continues, “This also implies that the nonresidential construction recovery will remain moderate. While ABC expects that nonresidential construction spending will advance over the balance of the year, the rate of improvement will continue to be constrained by an economy that still refuses to mount an aggressive expansion.”
