The relevance of microeconomics shown through real-world business examples One of the challenges of teaching principles of microeconomics is fostering interest in concepts that may not seem applicable to students lives.

With ever-changing US and world economies, the 7th Edition has been updated with the latest developments using new real-world business and policy examples. Regardless of their future career path -- opening an art studio, trading on Wall Street, or bartending at the local pub, students will benefit from understanding the economic forces behind their work.
