Take the following as truth: And if you look at any major textbook in international economics--such as the perennial best seller by Krugman and Maurice Obstfeld--you still find that the monetary half of the book is very largely based on the papers Mundell wrote in the early 1960s.
Then the following statement: "Mundell wrote some papers about economics that are now featured in textbooks." is true, false, or inconclusive?
Answer: Inconclusive
