WASHINGTON (Reuters) - U.S. retail sales rose more than expected in July as households boosted purchases of motor vehicles and clothing, suggesting the economy remained strong early in the third quarter.
Other data on Wednesday showed worker productivity growing at its fastest pace in more than three years in the second quarter, but a drop in labor costs pointed to moderate wage inflation. Strong domestic demand supports expectations the Federal Reserve will raise interest rates in September for the third time this year.
The Commerce Department said retail sales increased 0.5 percent last month. But data for June was revised lower to show sales gaining 0.2 percent instead of the previously reported 0.5 percent rise. Economists polled by Reuters had forecast retail sales nudging up 0.1 percent in July. Retail sales in July increased 6.4 percent from a year ago.
Excluding automobiles, gasoline, building materials and food services, retail sales advanced 0.5 percent last month after a downwardly revised 0.1 percent dip in June. These so-called core retail sales correspond most closely with the consumer spending component of gross domestic product.
Core retail sales were previously reported to have been unchanged in June. Consumer spending is being supported by a tightening labor market, which is steadily pushing up wages. Tax cuts and higher savings are also underpinning consumption.

July's increase in core retail sales suggested the economy started the third quarter on solid footing after logging its best performance in nearly four years in the second quarter.
Gross domestic product surged at a 4.1 percent annualized rate in the April-June period, almost double the 2.2 percent pace in the first quarter. While the economy is unlikely to repeat the second quarter's robust performance, growth in the July-September period is expected to top a 3.0 percent rate.
The Fed increased borrowing costs in June and forecast two more interest rate hikes by December.
Prices of U.S. Treasuries fell and the U.S. dollar added slightly to gains immediately after the release of the data. U.S. stock index futures were trading lower.
PRODUCTIVITY RISES
Last month, auto sales rose 0.2 percent after edging up 0.1 percent in June. Sales at clothing stores rebounded 1.3 percent after declining 1.6 percent in June. Receipts at service stations increased 0.8 percent.
Online and mail-order retail sales increased 0.8 percent, likely boosted by Amazon.com Inc's "Prime Day" promotion. That followed a 0.7 percent rise in June. Americans spent more at restaurants and bars, lifting sales 1.3 percent.
But receipts at furniture stores fell 0.5 percent and sales at building material stores were unchanged last month. Spending at hobby, musical instrument and book stores declined further in July, falling 1.7 percent.
In a separate report on Wednesday, the Labor Department said nonfarm productivity, which measures hourly output per worker, rose at a 2.9 percent annualized rate in the April-June quarter. That was the strongest rate since the first quarter of 2015.
Data for the first quarter was revised lower to show productivity increasing at a 0.3 percent pace instead of the previously reported 0.4 percent rate. Economists had forecast productivity growing at a 2.3 percent rate in the second quarter. Compared to the second quarter of 2017, productivity increased at a rate of 1.3 percent.
The government also revised data going back to 1947, which did not materially change the picture of lackluster productivity growth, though unit labor costs were stronger than previously estimated in 2017 because of upward revisions to hourly compensation.
The annual rate of productivity growth from 2007 to 2017 was revised up 0.1 percentage point to a rate of 1.3 percent.
Unit labor costs, the price of labor per single unit of output, fell at a 0.9 percent pace in the second quarter. That was the weakest pace since the third quarter of 2014. First-quarter growth in unit labor costs was revised up to a 3.4 percent rate from the previously reported 2.9 percent pace.
Labor costs increased at a 1.9 percent rate compared to the second quarter of 2017, pointing to moderate wage inflation.
