Friday's fourth-quarter GDP numbers offered more evidence that the economy is picking up steam, but one of the biggest obstacles to the recovery remains the stubbornly high unemployment rate. We'll find out whether there's been any movement on that front when employment data for January comes out this week. The Challenger Job-Cut report and ADP employment data are due Wednesday, and the government's unemployment rate on Friday. Another mild increase in jobs is expected, in line with the three-month average, but not enough to significantly reduce the unemployment rate.

Also look for the ISM manufacturing and nonmanufacturing indexes this week, as well as the Chicago PMI and the New York NAPM index. And Fed Chairman Ben Bernanke will speak to the National Press Club on Thursday.

A decline in revenues is forcing hotels into foreclosure. The aggressive deals being used to lure guests onto a property is helping to bring in some revenue, but it may not be enough. Occupancy is down 10%, which has sent hotel mortgages into delinquency faster than the rest of the commercial real estate industry.

And it could get worse next year. An oversupply of guestrooms could keep room rates low, making 2010 a high-risk year for hotel foreclosures. Demand should gain 1.6%, according to hotel research firm STR Global, but average room rates are likely to fall 3.4%. The result would be the greatest spread between demand and rates in the 20 years STR Global has been collecting data.
