Wharton's Peter Fader and Syracuse's Amanda Nicholson discuss Whole Foods' recent sales slump.

Organic food has become more popular among consumers, and it’s now easier to find in many grocery stores. But that’s not good news for Whole Foods, which once had a corner on the market. The retail chain recently announced its sixth consecutive quarter of same-store sales declines. During an earnings call on February 8, Whole Foods also said it will close nine stores in the second quarter of this year.

Wharton marketing professor Peter Fader and Syracuse University professor Amanda Nicholson recently appeared on the Knowledge at Wharton show on Wharton Business Radio on SiriusXM channel 111 to discuss the factors contributing to Whole Foods’ challenges, and how the chain can turn the tide.
