Economics
How people, firms and countries choose when they can't have everything, and how to tell what actually caused what.
For: anyone starting the degree, anyone who reads the economic news and wants to see under it, anyone who has wondered why prices rise.
Shaped by the cores of MIT's Course 14-1 (principles, intermediate theory, statistics and econometrics) and the LSE and Chicago programmes.
