📓 Understanding economic concepts often depends on an adequate understanding of the prior concepts on which subsequent concepts rest. This book tries to present the most basic economic concepts in easy-to-understand descriptions, in order to offer the best possible preparation for future study of microeconomics, macroeconomics, and international economics. Furthermore, the authors would contend that understanding these basic economic concepts is not only important for those planning further study, but also important for all consumers regardless of academic interest.
