3. Managerial Economics Lecture 1: Introduction  Microeconomics provides a set of tools for understanding how people behave  as consumers  as workers  as business managers  and in a variety of other roles.  These tools are helpful in designing and evaluating public policies  but they are never the whole story.

4. Managerial Economics Lecture 1: Introduction  Microeconomics is a new way of thinking.  But it is logical and anyone who tries can figure it out.  The key is practice.  If you are having trouble, do as many problems as you can!  Learn to be patient: Go step by step.

5. Managerial Economics Lecture 1: Introduction  Some people think economics is too technical:  How can one shed light on policy issues with tools that are beyond the reach of elected officials?!  But the main insights of economics are often simple and logical.  We will not go beyond graphs and simple algebra.
