A Harvard Business School study argues that credit card rewards are financed indirectly by higher prices, shifting an estimated $9.2 billion a year to wealthier cardholders and about $30 billion overall from cash and debit users to credit card users. The paper links this effect to interchange fees and to the Durbin Amendment, which lowered debit fees but also reduced debit rewards and shifted costs across consumers.
