video and audio clips in maths for economists
Many dozens of short tutorial videos on mathematical topics, especially calculus and algebra. Each lasts a few minutes and gives audio narration while you see the instructor's hand writing. The videos can be watched for free on YouTube.
A free archive of short broadcasts on Radio 4 in which Harford and guests critically examine statistics that are in the news, whether political, scientific, or sometimes whimsical. Questions have included "Is population density the right measure to be looking at when working out how many refugees countries should take?" "Why don’t all the opinion polls give the same results?" and "Is it true that Greece failed to collect 89% of taxes in 2010?"
Among the interviewees are Nobel laureates Angus Deaton and Al Roth. Episodes can be listened to online, and in podcasting software it is possible to subscribe and automatically download new episodes.
"A pre-sessional resource to refresh mathematical skills and techniques in preparation for an undergraduate degree in economics." Has more than eighty videos with captions, plus slides and interactive quizzes to cover seventeen topics from arithmetic and basic algebra to matrices, at each stage showing how these techniques are relevant to economics. Created with funding from the Royal Economic Society.
Web series that "crunches the numbers" about topics in the news. Each video is around 12 minutes long. The presenters are data & statistics journalists with the Financial Times.
- Is the inequality gap really widening?
- Is capitalism really ending poverty?
- Is economic growth fuelling climate change?

Five-minute animated video explaining the practice of overbooking, working through a numerical example that illustrates maximisation of a revenue function. It also discusses the randomness of customers not appearing and the binomial distribution of their number. The lesson includes a self-test quiz and links to text versions and interactive views of the calculation.
More than sixty short films explaining mathematical concepts by putting them in a real-world context, hosted by Ken Heather of the University of Portsmouth. Each video combines a live-action explanation of the idea followed by a numerical example which is worked through on-screen. Each film can be downloaded in low resolution or high-resolution Windows Media format, or viewed in YouTube. The animations can be viewed separately as Flash files that play in a web browser. The five categories are 1) Mathematical review, 2) Linear equations, 3) Mathematics of finance and growth, 4) Linear programming, and 5) Differentiation and integration.
