Led by higher prices for energy goods, prices at the producer level rose dramatically in November.
The Labor Department's Producer Price Index (PPI) for finished goods increased 2% last month, following declines of 1.6% in October and 1.3% in September.
The increase in the so-called core PPI was not as dramatic, although it was substantial. In November the core PPI increased 1.3%, compared to a nine-tenths percent decrease in October.
