You know, the total number of people deciding whether they're going to get rid of their petrol car and buy an electric car adds up to the total demand, the total increase in demand for electric cars and decrease in demand for petrol cars.

And then from that, you get from the total demand and total supply by companies bringing things to market, you get prices.

the aggregation, the bringing together of all those individual choices.

And that's the second thing that economics is about.

Firstly, it's about those individual choices.

Then it's about what all those choices add up to.

And they add up to lots of things.

They add up to interest rates.

They add up to how much the Aussie dollar is worth versus the US dollar.

They add up to inflation.

They add up to total government spending.

All of those macro things, they're interesting.

The micro of individual decisions adds up to the macro of

of exchange rates and interest rates and prices and government spending, et cetera.

And then the third thing, and it's a long answer, so I'll be briefer.

But the third thing is we're just sitting in the organizations that bring all that together.

The government, the banks, the super funds,

the companies, the unions, all of those kinds of organizations that facilitate that choice-making and all that economic activity.

We're interested in those organizations.

How do they work?
