13. Essence of Studying Economics
 To understand the world better
Applying the tools of economics can help you understand
global and cataclysmic events such as wars, famines,
epidemics, and depressions. Economics has the power to help
us understand these phenomena because they result from the
choices we make under the condition of scarcity.
 To gain self-confidence and become wise decisions makers
Mastery of economics will help you to understand how things
work in your society thereby “feeling equipped”
TheYoungIndianEconomists

14.  To achieve social change and contribute to National Development
Economics can help us understand the origins of serious social
problems such as: unemployment, hunger, poverty, disease,
child abuse, drug addiction, violent crime. It will also explain
why previous efforts to solve these problems have failed, and
help us to design new, more effective solutions.
 To help prepare for other careers
Economics has long been a popular college major for
individuals who are intending to work in business. But it has
also been popular among those planning careers in politics,
international relations, law, medicines, engineering, etc. This
is for good reason because practitioners in each of these fields
often find themselves confronting economic issues.
