The United States economy continued to expand from early October through mid-November with little inflation as retail sales, real estate markets and business service firms saw rising activity, a Federal Reserve survey showed.

The central bank's Beige Book economic report, which was based on information collected on or before Nov. 18 by regional Fed banks, said "outlooks were mainly positive" with half of the 12 districts "expecting moderate growth."

"A tightening in labor market conditions was reported by seven districts, with modest employment growth on balance," according to the Beige Book, released Wednesday in Washington. "Districts noted slight upward pressure on overall prices."

The job market is getting so competitive in the Chicago region that "it is getting more and more difficult to fill positions at any skill level," the report said, citing local business contacts. Construction work was delayed because of difficulties in finding workers, it said.

There were several references to the Nov. 8 U.S. presidential election scattered throughout the regional summary. The Richmond and St. Louis district contacts said softer vehicle sales "might be attributed to uncertainty surrounding the presidential election." Cleveland contacts reported that election "jitters" contributed to a decline in job openings and placements.

U.S. central bankers next meet Dec. 13-14. Futures traders have priced in a 100 percent probability of at least a quarter-point hike as the economy gets closer to the central bank's mandate of full employment and stable prices.

The Beige Book is a collection of anecdotes and information about economic conditions gathered by the regional Fed banks in their districts. This Beige Book was written by the Federal Reserve Bank of Cleveland.

The Fed's preferred price measure, the personal consumption expenditures price index, rose 1.7 percent for the year ending October, minus food and energy. The Fed has a 2 percent target for the full index, which increased 1.4 percent. The unemployment rate in October stood at 4.9 percent.
