This week, investors will be keeping an eye out for another batch of retail earnings, and Federal Reserve Chair Janet Yellen’s comments at the Fed’s Kansas City’s conference on the economy and monetary policy in Jackson Hole, Wyo. Here’s what you need to know about in business news today.

1. More intrigue in the dollar store world

Who’d have thunk that dollar stores could provide so much drama? This morning Dollar General bid $9.7 billion to buy Family Dollar, topping the bid of $8.5 million from Dollar Tree, the third major player in the space.

2. Urban Outfitters on the earnings catwalk

Weak earnings are expected to come from the retailer. Analysts expect a 5% dip from a year ago. This is driven largely by a downturn in sales from the namesake chain, while sales at Free People and Anthropologie are actually up.

3. Housing index numbers in focus

4. Global markets are up

U.S. stock futures are up sharply this morning, pointing to a positive start to the week. They are following gains in Europe and recovering from losses on Wall Street Friday. A significant factor in the Monday gains: receding fears about warfare in Ukraine.
