Query: Why is the Kindle Version More Costly Than Paperback

I cannot understand how a publisher can justify charging more for the Kindle version than paperback. It leads me to believe that as e-readers dominate the market place publishers are opting to gouge us with higher prices. It makes no sense when you consider they do not need to print or transport the books. So why the higher rate? Pure greed that ultimately hurts the authors because readers like myself refuse to buy the book.
