I’ve enjoyed reading and learning from Paul Krugman’s educational, clear and honest editorials in the New York Times for decades. Wanting still more, I spent the last ten months reading this excellent fourth edition of his textbook, coauthored with Robin Wells and published in 2015. It’s filled with very relevant, real world, illustrative examples from current events, especially the 2008 Great Depression. My copy’s title page was stamped by a high school in Minneapolis, and I think that’s the right level. Beginning Algebra is all the math you will need to understand the analysis of supply and demand, macroeconomics and exchange rates. Despite the modest difficulty level, there is much to learn from the book’s thirty-four chapters. The four chapters on taxes, Externalities, Public Goods, Common Resources and the welfare state are exceptionally clear and, despite Krugman’s reputation as a progressive, very fairly argued. I found the sixteen chapters of the second half of the book, on Macroeconomics, more interesting, probably because I am quite familiar with the microeconomic topics of the first half, having been in the engineering labor force for forty years. Highly recommended.
