Economics is all about the dynamics of interactions between people, resources, and the environment.

To understand how change works, you need to see it in action. Interactive Economics lets you do just that. Click, drag, type, and see what happens.

    Measuring Inequality

    Economic inequality is a defining issue of our time. In this module, we explore how inequality can be measured in ways that allow for comparisons across time and space.

    Many economic decisions involve time. In this module, we look at how people can transfer purchasing power from one period to another and the role played by interest rates.

Interactive Economics is part teaching tool, part playground.

We created Interactive Economics because students struggle to see how a static graph or equation explains the dynamic world they live in. When they ask ‘But what if?’, they should have a way to see the answer for themselves.

Interactive Economics does not replace your current textbook. It’s a free resource that helps you broaden the way you teach or learn. Each module covers an important concept in economics, like measuring inequality or output and inflation, and takes you through it step by step. At each step along the way, you get to play with data or models.
