In the later part of the 20th century, a pioneering group of economists started shaking up their academic field.

These “behavioural economists” used findings from experimental psychology and everyday life to challenge the prevailing view that human beings were rational decision makers – acting in predictable ways to maximize their wealth.

One of those pioneers was Richard Thaler, who noted down some of these “anomalies” in a column in the 1980s, which was turned into a book - The Winner’s Curse - first published in 1992. His work also won him the Nobel memorial prize in economics in 2017.

More than 30 years on, he has returned to that book, publishing a new, updated version with co-author Alex Imas, which looks at whether those anomalies in rational thinking have stood the test of time.

Tim asks him to set out two of his most famous ideas – the winner’s curse itself, and the idea of “mental accounting”.

For months, the share prices of tech companies have marched seemingly-ever upward, driven by fevered excitement about the potential of Artificial Intelligence. But many are now voicing fears that this surge might turn out to be a bubble, which could burst with damaging effects.

So do we have to rely on vibes? Or can we use data to tell us about the risk that AI might go pop?

The US Health Secretary Robert F. Kennedy Jr is on a mission to make America healthy again.

Vlad III Dracula, the Wallachian Prince who became Bram Stokers inspiration behind his famous vampire 'Count Dracula,' was a brutal ruler. So brutal that history dubbed him 'Vlad the Impaler' due to his penchant for that particularly gruesome form of execution. Which, without going into too much detail, involved driving a large stake or pole through someone's body - often vertically.

Chroniclers and historians claim that he impaled over 20,000 people during his reigns which, if true is a very, very big number. But is it true? We speak to Historian Dénes Harai whose paper: 'Counting the Stakes: A Reassessment of Vlad III Dracula’s Practice of Collective Impalements in Fifteenth-Century South-eastern Europe' attempts to set the record straight.

Let's travel back to 1431 to separate the math's from the myth.

Do you ever have fights with your partner about who does more of the housework and whether it’s fair? Well data might have the answer.

Corinne Low is an associate professor at the Wharton School at the University of Pennsylvania. She analyses surveys of how people spend their time, particularly in terms of “home production” - that is things like cooking and cleaning, and “market work”, that is, paid work.

If you’re the male half of a heterosexual couple, then she’s got some stats you should hear.

Tim sat down to talk it all over while Corinne was in the UK to promote her new book on the subject - titled Femonomics in the UK, and Having It All in the US.

Joel Mokyr, Philippe Aghion and Peter Howitt have been awarded this year’s Nobel Memorial Prize in Economic Sciences.

The three are sharing 11 million Swedish kronor, over a million dollars, after being recognised for their work in the area of “innovation-driven economic growth”. But why does this area matter and what did the three economists actually do?

Tim Harford investigates some of the numbers in the news. This week:

The Conservative party conference has been told that millions of people are getting free cars from the government because they have ADHD and anxiety. Is that right?

The chair of the Labour party says that only 3% of farmers will be affected by proposed changes to inheritance tax. Is that true?

The charity Movember claim that two in five men die too young. What does that really mean?

And Tim’s mid-life crisis has manifested itself in a marathon run. We ask a scientist if data can help him finish faster.

In a recent speech to the UN, US president Donald Trump set out some remarkable figures on the proportion of inmates in European prisons who were foreign nationals.

Citing statistics from the Council of Europe, he references Greece, Germany and Austria, as having rates around 50%.

“In Switzerland, beautiful Switzerland,” he said “72% of the people in prisons are from outside of Switzerland.”

Tim Harford speaks to Professor Marcelo Aebi, a criminologist from the University of Lausanne, who wrote the prisons report for the Council of Europe.
