Economics plays a vital role in making modern civilization function, so studying economics helps experts learn how to prevent problems. Studying economics also helps when running or managing a business. Economics is often viewed as a scientific field.
In many ways, modern civilization is based on money. Countries need money to pay for the work they need done, and businesses and governments, which fuel economies, need money to make investments and provide goods and services. The study of economics prepared people for filling these roles, and its study covers a broad range of skills needed to work effectively.
Economics can seem deceptively simple at first, but it is a multidisciplinary field that requires a number of different skills. At the heart of economics is mathematics. Calculating how much a product or service is worth is important, and knowing how interest rates affect prices is critical as well. Economists need to rely on calculus for a wide range of problems.
However, many economists believe that the field is primarily about psychology and human behavior. Effective economic work requires knowing how people will react and learning what they are interested in purchasing. Economists can make accurate predictions in certain areas; in others, modern economics provides little guidance.
