One of the common factors observed in different exchange rate regimes, political systems, and financial markets is the occurrence of large current account deficits. This means that countries are becoming increasingly indebted to the rest of the world over time.
Carmen Reinhart of the University of Maryland talks with EconTalk host Russ Roberts about the ideas in her book This Time is Different: Eight Centuries of Financial Folly (co-authored with Kenneth Rogoff). They discuss the role of capital inflows in financial crises, the challenges of learning the right lessons, and what is generally true about financial crises over time and place. Reinhart applies these observations to the current crisis, discusses the possibility of the U.S. defaulting on its sovereign debt, and discusses the possibility of financial reforms that might make a difference.
