Kimbers, just go back and see what the drivers of GDP per capita are/were? Ask yourself, are they/were they sustainable? Were they just (ever so slightly!) un-balanced (true in all three cases actually).
At best Iceland and Ireland are good examples of how rel. small economies can be very vulnerable to unbalanced and unsustainable growth drivers and unable to deal with the consequencies that may result. They also give different case studies on how to deal with (in effect) national bankruptcies. I would not want to wish that on Scotland but there a lessons to be learned.
But re the UK, the hit to GDP per capita has been more severe in the current recession than in previous ones for various reasons. The simplest is that population growth has been much more (@4%) than in previous recessions. As we all know the hit to average incomes has also been relatively high with a knock on effect on consumption....And inflation has also been relatively high making the hit to nominal household income even worse. There's more, but that will do for now!!!
