50 Things That Made the Modern Economy - Limited Liability Company

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. Producer: Ben Crighton Editors: Richard Knight and Richard Vadon (Image: LLC. Credit: Getty Images)

50 Things That Made the Modern Economy - Dynamo

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.

50 Things That Made the Modern Economy - Leaded Petrol

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.

50 Things That Made the Modern Economy - Department Store

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.” Producer: Ben Crighton Editors: Richard Knight and Richard Vadon (Images: Selfridges Christmas shop window, Credit: Stuart C.

Undiscovered - Mouse’s Vineyard

Martha’s Vineyard has a Lyme disease problem. Now a scientist is coming to town with a possible fix: genetically engineered mice.

An island associated with summer rest and relaxation is gaining a reputation for something else: Lyme disease. Martha’s Vineyard has one of the highest rates of Lyme in the country. Now MIT geneticist Kevin Esvelt is coming to the island with a potential long-term fix. The catch: It involves releasing up to a few hundred thousand genetically modified mice onto the island. Are Vineyarders ready?

50 Things That Made the Modern Economy - Barbed Wire

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.

Undiscovered - Kurt Vonnegut and the Rainmakers

In the mid 1940s, no one would publish Kurt Vonnegut’s stories. But when he gets hired as a press writer at General Electric, the company’s fantastical science inspires some of his most iconic--and best-selling--novels.

Imagine the Earth has been turned into a frozen wasteland. The culprit? Ice-nine. With a crystalline structure that makes it solid at room temperature, ice-nine freezes every drop of water it comes into contact with, and (predictably) ends up destroying the world. This is the fantastical plot of Kurt Vonnegut’s 1963 novel, Cat’s Cradle. But the science that inspired the fiction came from the real-life research his older brother and team of scientists at General Electric conducted just after World War II.

General Electric might be best known for manufacturing refrigerators and light bulbs, but in the 1940s, the GE scientists joined forces with the military and set their sights on a loftier project: controlling the weather.

Controlling the weather could mean putting an end to droughts and raining out forest fires. But the GE scientists’ military collaborators have more aggressive plans in mind. Kurt, a pacifist, closely watches GE’s saga unfold, and in his stories, he demands an answer to one of science’s greatest ethical questions: are scientists responsible for the pursuit of knowledge alone, or are they also responsible for the consequences of that knowledge?
