If economics was made more relatable, it would be easier to understand.

Justin Wolfers says we should start by teaching it differently.

He says that although the guiding principles have largely remained, they need to be pulled apart and used in everyday decision-making to be useful.

And if you don't want to study at university, there are some great resources to guide you through say, a pandemic.

Justin Wolfers is a professor of economics and public policy at the University of Michigan and a senior fellow at the Peterson Institute for International Economics.

He co-authored (with Betsey Stevenson) Principles of Economics.
