Plastic Aug 12, 2017

Show notes

A couple of decades after Leo Baekeland invented the first fully synthetic plastic – Bakelite – plastics were pouring out of labs around the world. There was polystyrene, often used for packaging; nylon, popularised by stockings; polyethylene, the stuff of plastic bags. As the Second World War stretched natural resources, production of plastics ramped up to fill the gap. And when the war ended, exciting new products like Tupperware hit the consumer market. These days, plastics are everywhere. We make so much plastic, it takes about eight percent of oil production – half for raw material, half for energy. And despite its image problem, and growing evidence of environmental problems, plastic production is set to double in the next 20 years.

Seller Feedback Aug 05, 2017

Show notes

Why should we get into a stranger’s car – or buy a stranger’s laser pointer? In 1997, eBay introduced a feature that helped solve the problem: Seller Feedback. Jim Griffith was eBay’s first customer service representative; at the time, he says “no-one had ever seen anything like [it]”. The idea of both parties rating each other after a transaction has now become ubiquitous. You buy something online – you rate the seller, the seller rates you. Or you use a ride-sharing service, like Uber – you rate the driver, the driver rates you. And a few positive reviews set our mind at ease about a stranger. Jim Griffith is not sure eBay would have grown without it. Online matching platforms would still exist, of course – but perhaps they’d be more like hitch-hiking today: a niche pursuit for the unusually adventurous, not a mainstream activity that’s transforming whole sectors of the economy.

Paper Money Jul 29, 2017

Show notes

A young Venetian merchant named Marco Polo wrote a remarkable book chronicling his travels in China around 750 years ago. The Book of the Marvels of the World was full of strange foreign customs Marco claimed to have seen. One, in particular, was so extraordinary, Mr Polo could barely contain himself: “tell it how I might,” he wrote, “you never would be satisfied that I was keeping within truth and reason”. Marco Polo was one of the first Europeans to witness an invention that remains at the very foundation of the modern economy: paper money. Tim Harford tells the gripping story of one of the most successful, and important, innovations of all human history: currency which derives value not from the preciousness of the substance of which it is made, but trust in the government which issues it.

Limited Liability Company Jul 22, 2017

Show notes

Nicholas Murray Butler was one of the great thinkers of his age: philosopher; Nobel Peace Prize-winner; president of Columbia University. When in 1911 Butler was asked to name the most important innovation of the industrial era, his answer was somewhat surprising. “The greatest single discovery of modern times,” he said, “is the limited liability corporation”. Tim Harford explains why Nicholas Murray Butler might well have been right.

Dynamo Jul 15, 2017

Show notes

You might think electricity had an immediate and transformative impact on economic productivity. But you would be wrong. Thirty years after the invention of the useable light bulb, almost all American factories still relied on steam. Factory owners simply couldn’t see the advantage of electric power when their steam systems – in which they had invested a great deal of capital – worked just fine. Simply replacing a steam engine with an electric dynamo did little to improve efficiency. But the thing about a revolutionary technology is that it changes everything. And changing everything takes imagination. Instead of replacing their steam engines with electric dynamos, company bosses needed to re-design the whole factory. Only then would electric power leave steam behind. As Tim Harford explains, the same lag has applied to subsequent technological leaps – including computers. That revolution might be just beginning.

Leaded Petrol Jul 08, 2017

Show notes

In the 1920s lead was added to petrol. It made cars more powerful and was, according to its advocates, a “gift”. But lead is a gift which poisons people; something figured out as long ago as Roman times. There’s some evidence that as countries get richer, they tend initially to get dirtier and later clean up. Economists call this the “environmental Kuznets curve”. It took the United States until the 1970s to tax lead in petrol, then finally ban it, as the country moved down the far side of the environmental Kuznets curve. But as Tim Harford explains in this astonishing story, the consequences of the Kuznets curve aren’t always only economic.

Department Store Jul 01, 2017

Show notes

Flamboyant American retailer Harry Gordon Selfridge introduced Londoners to a whole new shopping experience, one honed in the department stores of late-19th century America. He swept away previous shopkeepers’ customs of keeping shopper and merchandise apart to one where “just looking” was positively encouraged. In the full-page newspaper adverts Selfridge took out when his eponymous department store opened in London in the early 1900s, he compared the “pleasures of shopping” to those of “sight-seeing”. He installed the largest plate glass windows in the world – and created, behind them, the most sumptuous shop window displays. His adverts pointedly made clear that the “whole British public” would be welcome – “no cards of admission are required”. Recognising that his female customers offered profitable opportunities that competitors were neglecting, one of his quietly revolutionary moves was the introduction of a ladies’ lavatory. Selfridge saw that women might want to stay in town all day, without having to use an insalubrious public convenience or retreat to a respectable hotel for tea whenever they wanted to relieve themselves. As Tim Harford explains, one of Selfridge’s biographers even thinks he “could justifiably claim to have helped emancipate women.”

Barbed Wire Jun 24, 2017

Show notes

In 1876 John Warne Gates described the new product he hoped to sell as “lighter than air, stronger than whiskey, cheaper than dust”. We simply call it barbed wire. The advertisements of the time touted it this fence as “The Greatest Discovery Of The Age”. That might seem hyperbolic, even making allowances for the fact that the advertisers didn’t know that Alexander Graham Bell was just about to be awarded a patent for the telephone. But – as Tim Harford explains – while modern minds naturally think of the telephone as transformative, barbed wire wreaked huge changes in America, and much more quickly.

Tax Havens Jun 17, 2017

Show notes

The economist Gabriel Zucman is the inventor of an ingenious way to estimate the amount of wealth hidden in the offshore banking system. In theory, if you add up the assets and liabilities reported by every global financial centre, the books should balance. But they don’t. Each individual centre tends to report more liabilities than assets. Zucman crunched the numbers and found that, globally, total liabilities were eight percent higher than total assets. That suggests at least eight percent of the world’s wealth is illegally unreported. Other methods have come up with even higher estimates. As Tim Harford explains, that makes the tax haven a very significant feature of the modern economy.

Infant Formula Jun 10, 2017

Show notes

Not every baby has a mother who can breastfeed. Indeed, not every baby has a mother. In the early 1800s, only two in three babies who weren’t breastfed lived to see their first birthday. Many were given “pap”, a bread-and-water mush, from hard-to-clean receptacles that teemed with bacteria. But in 1865 Justus von Liebig invented Soluble Food for Babies – a powder comprising cow’s milk, wheat flour, malt flour and potassium bicarbonate. It was the first commercial substitute for breastmilk and, as Tim Harford explains, it has helped shape the modern workplace.
