The definitive source in the field of micro- and macroeconomics.
Economics is essentially the study of a process we find in all human societies - "the" economic problem is simply the process of providing for the material well-being of society. In its simplest terms - economics is the study of how man earns his daily bread.
I used this textbook in college; since I got an A in the class, I can say that the book explains economics very well.
