TITLE: Reference for Mathematical Economics
QUESTION [17 upvotes]: I'm looking for a good introduction to basic economics from a mathematically solid(or, even better, rigorous) perspective. I know just about nothing about economics, but I've picked up bits and pieces in the course of teaching Calculus for business and social sciences, and I'd like to know more, both for my personal culture and to incorporate into my courses. My Platonic ideal of such a book would be along the lines of T W Körner's Naive Decision Making, but I'll take what I can get.

REPLY [9 votes]: Let me first tell you that there are three types of economic theory:

price theory
general equilibrium
game theory

Nowadays, the last type of theory is by far the most popular, but maybe you need some familiarity with the other two to appreciate game theory as an economist does. I guess you could say the mathematics is very easy judged from what mathematicians are used to. What is difficult is the economic interpretation. For that you need a bit economic intuition and a bit of culture about classic economic models.
My recommendations for a mathematically mature neophyte would be:

george stigler's price theory for the first
debreu's classic for general equilibrium; there is also a book by JWS Cassels
Fudenberg & Tirole or Vega Redondo for game theory
