It is very simple and straightforward, but we still find it hard to explain it to students. Our hope is that the distinguished community of theoretical economists may help us solve this mystery. After all, we would find it extremely unlikely that we are the first persons to identify this paradox.</p>}, number={1}, journal={Economics and Business Letters}, author={Haugen, Kjetil and Heen, Knut P.}, year={2021}, month={Feb.}, pages={69–71} }
