Economics can be defined as the study how scarce resources can be used to satisfy human wants or needs. Economics is a discipline which studies man’s endeavor to satisfy his unlimited wants out of the given scarce resources. Economics deals with how people allocate finite resources. There is a tendency to act by fulfilling their own interests that result into selfishness, greed among other undesirable traits. In a bid to satisfy his needs, man tries to allocate resources in an efficient manner.
