Sleep Soundly
Money illusion is just about the most venerable of all of the behavioural biases that afflict people’s financial good sense. It was recognised back in the early part of the twentieth century, was an integral part of financial theories from thereon and spawned a range of measures that are more or usually less useful to us in everyday life.

Which led to various predictable, albeit unpleasant, consequences such as believing “you can’t go wrong with property” or that storing cash in your mattress equates to sensible financial planning.

In fact, in the case of the euro it almost certainly isn’t what it was when you started reading this. This fact, however, doesn’t stop us from almost exclusively focussing on how much money we have today rather than what it can purchase for us:…
