The carbon cost of breakfast at COP26
A French minister told people to eat fewer croissants at this year’s COP26 summit, after the menu said the carbon cost of the pastry was higher than that of a bacon roll, even if it was made without butter. Tim Harford investigates whether this claim could be true, and how the effect of food on climate change can be measured.

Same data, opposite results. Can we trust research?
When Professor Martin Schweinsberg found that he was consistently reaching different conclusions to his peers, even with the same data, he wondered if he was incompetent. So he set up an experiment.
What he found out emphasises the importance of the analyst, but calls into question the level of trust we can put into research.

The numbers behind Squid Game
Netflix has announced that South Korean survival drama Squid Game is its most popular series ever.

The prize-winning economics of migration and the minimum wage
Do immigrants drive down wages, do minimum wage increases reduce job opportunities, and do people who did well in school earn more money?
These are questions that the winners of the 2021 Nobel Memorial Prize in Economics looked to the world around them for answers to.
David Card, Joshua Angrist, and Guido Imbens developed ways of interpreting what they saw that changed the way economists think about what they see.
In this episode of More or Less, presenter-turned-guest Tim Harford explains how.
