50 Things That Made the Modern Economy

Gyroscope Apr 08, 2019

Show notes

When the HMS Victory sank in 1744, with it went an inventor named John Serson and a device he’d dreamed up. He called it the “whirling speculum”, but we now know the basic idea as a gyroscope. Serson thought it could help sailors to navigate when they couldn’t see the horizon. Nowadays gyroscopes are tiny and, as Tim Harford describes, they are used to guide everything from submarines to satellites, from rovers on Mars to the phone in your pocket. They are also integral to drones – a technology that some believe could transform how we do our shopping. But for that, they’ll need to work in all weathers.

Cellophane Apr 01, 2019

Show notes

Plastic food packaging often seems obviously wasteful. But when Jacques Brandenberger invented cellophane, consumers loved it. It helped supermarkets go self-service, and it was so popular Cole Porter put it in a song lyric. Nowadays, people worry that plastic doesn’t get recycled enough but there are two sides to this story. Plastic packaging can protect food from being damaged in transit, and help it stay fresh for longer. Should we care more about plastic waste or food waste? As Tim Harford explains, it isn’t obvious and the issue is complicated enough that our choices at the checkout may accidentally do more harm than good.

Langstroth Hive Mar 25, 2019

Show notes

Humans have valued bees for their honey for thousands of years – and economists have long admired bees for their cooperative work ethic, too. But few of us, whether economists, honey-lovers, or both, have quite appreciated just how much the honey bee has been industrialised – and the simple yet radical invention that made that industrialisation possible. As Tim Harford explains, it is a sign of just how far the modern market economy has penetrated that it now reaches deep into the heart of the beehive.

Index Fund Jan 17, 2019

Show notes

Warren Buffett is the world’s most successful investor. In a letter he wrote to his wife, advising her how to invest after he dies, he offers some clear advice: put almost everything into “a very low-cost S&P 500 index fund”. Index funds passively track the market as a whole by buying a little of everything, rather than trying to beat the market with clever stock picks – the kind of clever stock picks that Warren Buffett himself has been making for more than half a century. Index funds now seem completely natural. But as recently as 1976 they didn’t exist. And, as Tim Harford explains, they have become very important indeed – and not only to Mrs Buffett.
