Guillermo Calvo, who foresaw the financial crisis that followed the devaluationn of Mexico's peso, has spent much of his career thinking beyond the conventional wisdom. In a quiet and understated way, Calvo has made seminal contributions to several major research areas in macroeconomics, particularly monetary policy, exchange rates, public debt, and stabilization in Latin America and post-communist countries. Money, Exchange Rates, and Output brings together these contributions in a broad selection of the author's work over the past two decades. There are introductions to each section, and an introduction to the entire collection that outlines the connections throughout and survey the current state of macroeconomic theory. . Specific issues covered are predetermined exchange rates, currency substitution, domestic public debt and seigniorage, and stabilizing transition economics.
