Where can I find economics theories to learn about? I'm a beginner to economics so I do not have much knowledge. However, I enjoy learning new economics theories. For now, I normally search for economics theories by looking at those that won nobel prize. Do you know where can I find a list of other economics (particularly microeconomics) theories that don't win the nobel prize?
Thank you very much.
You should read the fundamentals. I strongly suggest two textbooks for microeconomics:

Hal Varian - Microeconomics
Snyder, Nicholson - Microeconomic Theory

If your read any of the two and find it confusing, I suggest you go for:

Mankiw, Taylor - Economics
