BBC: Paris speed limit falls to 30km/h

Article published: 30 Aug,  2021

IB Economics syllabus: Microeconomics (market failure, externalities, government intervention)

The speed limit has been reduced to 30km/h in most of Paris among other French cities in an attempt to reduce “accidents, and reduce noise and pollution.” This is a great article to use for market failure and a government response, as cars lead to negative consumption externalities and hence can be considered demerit goods. The key concept can be sustainability, change and even intervention. The policy has a lot of pros and cons so it’s relatively easy to produce a great evaluation too.
