Essentials of Economics: Standalone book- 10th Edition
Every decision in the economic world revolves around opportunity cost. There are no sure deals that many services or products will be provided at a very low-cost if something else crucial is foregone. Such problems affect the social, political and the economic spheres in the long run. These problems have to be addressed in conjunction with the micro problems. The traditional classroom way of teaching has already ended; teachers have to teach with the current economic examples because it is the reality.
