The Weird Economics of Cellular Calling Plans

Yesterday’s New York Times has an amusing article about the complexities of cell phone pricing (ht: Carolyn):

Let’s go to the video:

I should emphasize that the message is not that economists are bow-tie-wearing geeks who should be sprayed with garden hoses. That may be true, but it isn’t CZJ’s message to policymakers.

No, the special message of the T-Mobile ad is that …  Continue reading “Catherine Zeta-Jones & Consumer Finance”
