  • What is Behavioural Economics?

    Behavioural economics is one of the major intellectual developments of the past 50 years. This scientific field became popular thanks to the work of the psychologists Daniel Kahneman and Amos Tversky who managed to identify and analyse many of the core biases in human cognition. However, the richest precedent for behavioural economics is in the works of ancient Greek philosophers. Almost 2,500 years before the current vogue for behavioural economics, Plato was identifying and seeking to understand the predictable irrationalities of the human mind.

  • Are these masterclasses available now?

    Some of them are so you can start learning today. There are more coming up, where you can pre-enroll and take advantage of special offers.

  • Are there any seniority pre-requisites?

    No. We believe that everyone can benefit from these courses. However, more senior professionals (Directors and Department Heads) tend to gain more value as 1)the courses challenge what they have learned and 2)they are in position to implement what they learn and see results straight away.

  • Do I get a discount for more users?

    Yes. If you are interested in getting 5 or more enrolled, we will send you a special coupon. Just send us an email at

  • How much time do I have to complete each course?

    A month or a lifetime! Masterclasses take 3-4 weeks to complete. However, we believe that knowledge is something you will come back again and again for inspiration. For this reason, we have also created a lifetime access. In this case, you will take advantage of any extra material we may add in the future, at no extra charge.

  • How do I pay for the courses?

    You can pay using your credit card or through Paypal, receiving a receipt immediately (keep in mind that this is an educational activity so no VAT is applied). If this way does not suit you, feel free to contact us at +30.210.7243001 or
