De Econometrist
De Econometrist takes a statistical look at the world.
A crash course in general equilibrium theory
I have always had a weakness for history lessons. Although very different from the standard optimal control problems and differential equations I am solving in my studies, I find that the lessons we can learn from great previous minds are both insightful and...
The Coming Recession – Why There Will Probably Be a Recession Next Year
We are living in economically tumultuous times, with high inflation, rapid interest rate rises, and an energy and climate crisis interfering with the economy. Many economic institutions talk of the imminence of a global recession. This fact gives rise to the question:...
Why do cities often have a poor east side?
London, New York, Paris, Toronto, Manchester: all cities where poverty tends to gather in the east. For each of these cities, one could think of explanations for this on an individual basis. In London for example, the river Thames flowed eastwards. Since in the past...
Van Gogh – not just a painter
Van Gogh is undoubtedly one of the most famous painters of all time, but perhaps it’s time to consider him a mathematician. Starry Night is one of Van Gogh’s most renowned paintings, depicting just that: a starry night. With a bright moon on the right, and Venus in...
How to read a QR code without your phone
You can see them almost everywhere nowadays: QR codes. They can be used for all kinds of things: showing you the menu in a restaurant, getting wifi and even paying for something via a ‘Tikkie’. The first time I saw such a QR code, I wondered immediately how it works,...
A triangle that changed the world
When you think of mathematics you imagine a sea of numbers, formulae and relationships. This is of course, as we know, quite often the case. However, mathematics hides quite interesting relationships you might have not yet thought of before. One of the most common...
How many beers are consumed on the average VESTING Social?
Note: This article is part of a multi-part series called ‘Berke Revisits’ in which Berke looks back at old articles that he has written, and sheds some perspicacity on ideas, thoughts, and concepts of the old articles, all wrapped in a nice, easy to read, format. You...
Winning in Martial Arts: A Data-Driven Strategy
As a martial arts practitioner and fan, I have recently become more interested in the applications of data science to the fields of martial arts. As you may know, during a fight, data is collected in the form of video and observations. This data is used to determine...
Bayesian Statistical Inference
Statistical inference is the use of data analysis to say something about the probability distribution of the underlying data. A very common tool to say something about the likely distribution of data is the method of maximum likelihood. Here we make an assumption of...
Why all horses have the same colour
What if I told you that all horses have the same colour? And that 2 = 1? And, to top it off, that I could prove it? You would probably say I’m delusional and that my proof must contain a mistake. However, there are proofs that do not contain mistakes which conclude...
Eating your cake the right way
For some reason I always have a hard time making inter-temporal decisions. Should I drink a few more beers tonight, taking into account that I have a lecture at 9 am tomorrow? Should I buy that new piece of clothing or save to accumulate some (possibly negative)...
Are we alone in the Universe?
Since the beginning of civilization, humans have looked up into the sky and wondered whether we are alone in the Universe. Since then our technology has come quite a way and it feels like we can make a better-educated guess to this question. We currently estimate that...
The Ewing Theory
What happens if your team’s best player goes down with an injury, leaves for another team or retires? Your team should be less successful, right? Well, as it turns out, this is not necessarily always true. Sometimes, a team can inexplicably flourish without their...
Why your Dobble cards always match
Dobble: a game played by kids, but still very popular among adults. In the game, you have to draw two random cards and place them face-up on the table between all the players. Then, you have to look for the identical symbol between the two cards. Between every two...
