What is a toolkit? - Economists have a particular way of looking at the world. - They see “optimizing” or “maximizing” behavior everywhere. - When individuals or businesses try to maximize, their behavior becomes predictable according to the basic models of microeconomics. - The toolkit shows you how this works so you can start working like an economist right away. - We use this toolkit all the time - If you pay careful and close attention you will notice a theme or a modus operandi running throughout nearly all of our discussions. o Set up an optimizing problem or model o Figure out how the model works and what characterizes a solution o Use the model to make predictions concerning how the players in the model react to changes in their environment o Test and/or apply the model. Maximizing Behavior - An individual or a business maximizes when it tries to do the best action possible according to a particular objective. - Usually that objective can be summarized as the difference between the total benefits and the total costs of the action. - Maximizing behavior means that one makes the difference between total benefits and total costs as big as possible.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
