WASHINGTON (AP) — Wholesale prices in the United States rose last month, remaining low but suggesting that the American economy has yet to completely vanquish inflationary pressure. Thursday's report from the Labor Department showed that its producer price index — which tracks inflation before it hits consumers — rose 0.2% from September to October, up from a 0.1% gain the month before. Compared with a year earlier, wholesale prices were up 2.4%, accelerating from a year-over-year gain 1.9% in September.
