Here in Mexico you can have two main kinds of economics in undergrad. If you are majoring in Economics, then you have one type of econ courses that begin with a term using Samuelson or Fischer/Dornbusch or something similar. Then you get on twwo streams: micro wwith Varian (intermediate then Analysis) and macro with whoever (lately starting with (I dont remember the name, he is very famous now, best selling in textbooks) and maybe going to Sargent's Macroeconomics or even Blanchard/Fischer, etc.). If you are not going into economics for a living, then you stay at the Samuelson or similar level. I just wrote a book (a year from now) for this kind of courses trying to cover three issues: a) Including most perspectives: neoclassical, keynesian, empirical issues, obviously at a introductory level. b) That the book could be read with joy (it has some jokes on it), c) That mexicans learn about the mexican economy as well as some theoretical issues, all the examples in the book (most I should say) come from Mexico or Latin American countries. The book is doing well, about 8000 sold, which for Mexico is a very big number. There is still another line of thought here. Most public universities became invaded by Marxism in the 70s. Some of them have not change by now, so they still read "Das Kapital", some sovietic manuals and similar things. Nevertheless, this is fading out. If the question goes about different schools of though like post-keynesian, neo-ricardian, institutional, neoclassical, etc. Forget it. Neoclassical covers almost everything. In undergraduate, all.
