For the past several years I have been studying economics. First I read N. Gregory Mankiw’s elementary text “Principles of Macroeconomics”. After reading several elementary texts and popular accounts I began to build my own model economy, and eventually lectured about the model at the Midwest Dynamical Systems Conference at the University of Michigan. Carl Simon, who teaches mathematical economics at Michigan was in the audience and he told me what I was doing had already been done, and that I should read some graduate economics texts.
My next step was to attend Martin Boileau’s graduate course in macroeconomics at the University of ŷڱƵ (fall 2005) using David Romer’s “Advanced Macroeconomics” text. Next I attended Anna Rubinchik’s advanced graduate course in microeconomics using “Microeconomic Theory” by Mas-Colell, Whinston, and Green. In 2006-2007 I audited courses in international macroeconomics using “Foundations of International Macroeconomics” by Obstfeld and Rogoff, and a course in international trade by James Markusen using his lecture notes. In 2007-2008 I attended the graduate environmental economics courses taught in the fall by Nick Flores and in the spring by Randy Walsh. I also attended an econometrics class taught by Don Waldman using the text “Econometric Analysis” by W. H. Greene. In the fall 2013 I audited nonparametric statistics taught by Carlos Martins-Filho.
