It helps to know basic supply and demand (25, 4, 7 and 21, 2, 10) and the idea of substitute goods (28, 1, 17 and 26, 3, 3) but are there other economics concepts that appear on LR?

I know we don't have to know the specifics but familiarity with them would definitely help non-econ majors like me

would appreciate any help!
