Economics applies the concepts and methodologies of the natural sciences and mathematics to problems in business, the social sciences and the humanities. With the major changes that have taken place in the world of work, the rapid changes in technology and globalization, it is not uncommon for individuals to make several career changes during their lives. Today's hot specialized degree has often become tomorrow's target for downsizing. Companies that were relatively unchallenged in the domestic market have suffered as a result of global competition. As a result, experts in career development recommend that one seriously consider a flexible degree such as economics. Economics is a discipline in which you learn a unique way of thinking. This unique way of thinking is a primary reason that economics is also a flexible degree.
