Economists' Mathematical Manual, 4th Edition

This volume presents mathematical formulas and theorems commonly used in economics. It includes both formulas like Roy's identity that are peculiar to economics and formulas like Leibniz's rule that are common to many areas of applied mathematics. The volume is meant to be a reference work, to be used by students in conjunction with a textbook and by researchers in need of exact statements of mathematical results. The volume is the first grouping of this material for a specifically economist audience.
