Business Administration
Business administration is the study of how businesses function, and gives a broad introduction to the various areas of a business. These areas include marketing, finance, accounting, human resources and business development. A bachelor's degree in business administration is a special degree shortened to BBA. While business administration incorporates many economic ideas, a business administration degree tailors itself more narrowly than economics by focusing on how individual businesses run.

Economics
Economics studies the production and consumption of goods in society. It is a social science like anthropology or sociology. Economists may study how individuals in aggregate make decisions in a greater economy, called microeconomics, or how the economy works as a whole, called macroeconomics. While economics involves business, economists do not study how an individual business runs or could improve. Economics focuses on the broader implications of what many individual businesses choose to do.
