Karl Smith is the director of economic research at the Niskanen Center. He joins the show to discuss his thoughts on increasing market power (the ability of firms to influence prices) in the United States. Karl argues that this is at least partially due to what he calls the \u201cGreat Variation,\u201d the desire many Americans have had for more individualized consumer goods since the 1960s. Finally, Karl also shares his thoughts on some of President Trump\u2019s choices for Federal Reserve chair.
