WASHINGTON — Consumers opened their wallets and pocketbooks a bit more in June, increasing their spending for the second straight month while saving less, even as incomes fell sharply.

Consumer spending is closely watched because it accounts for about 70 percent of total economic activity. Many economists warned that despite the slight increase in June, falling wages and rising unemployment likely will keep spending sluggish for the rest of this year.

Still, the housing market continued to show signs of life as pending U.S. home sales rose in June for the fifth straight month, according to the National Association of Realtors. The group's pending home sales index rose more than expected to 94.6, from an upwardly revised reading of 91.3 in May. The last time there were five straight monthly gains was July 2003.

The Commerce Department said today consumers boosted their spending 0.4 percent in June, slightly ahead of analysts' estimates. That comes after spending rose 0.1 percent in May.

Incomes benefited in May from a one-time payment of $250 that was mailed to 50 million Americans receiving Social Security and other government benefits, as part of the Obama administration's $787 billion stimulus package.

Excluding the impact of the stimulus, personal income would have fallen 0.1 percent in June after a flat reading in May, the department said.
