Greg Mankiw - Paul Krugman has several posts discussing the burden of the national debt. Some readers have asked me for my take on the topic. Let me refer them to this old paper Greg Mankiw wrote with Larry Ball. It provides a nontechnical overview. Even though it is 16 years old, I think it holds up pretty well.
