A fundamental assumption for economic analysis is that economic agents, be it an individual, a household or a firm/business, tend to make choices and select alternatives rationally. The rational economic choice (decision) implies that people are driven by the rational pursuit of self-interest, and engaged in economic decisions to maximize this self-interest. By rational economic choice , economists mean that people try to make the best choice they can, given the available resources at their disposals (money, time, etc.) and information. Self-interest is when individuals make economic decisions that are in their own best interest. On the other hand, s ocial interest is when choices are made that benefit society as a whole. Economists argue that social interest can be attained by individual decision makers acting in their own self-interest. This process is what Adam Smith called the invisible hand , which has been the foundation of the market economy. Create an example to demonstrate how an individual or firm acting out of self-interest to maximize profits by offering goods or services in economic markets benefit consumers – even if they do not care about them. In other words, how does self-interest help achieve society’s economic goals? What is the relationship between self-interest and social interest in the economic decision (economic choice) process? Is there a conflict between the two in the economic world .
