Ms Shelton called on the Fed to “think about whether they are doing more harm than good”. If appointed to the board, she would be “asking tough questions” about its most basic mission, she said. “How can a dozen, slightly less than a dozen, people meeting eight times a year, decide what the cost of capital should be versus some kind of organically, market supply determined rate? The Fed is not omniscient. They don’t know what the right rate should be. How could anyone?” Ms Shelton said.
