The marginal utility of birthdays

No BERL economists were invited to Mr Pink's birthday party last night, and it was probably just as well. They would have been shocked at the zero-function drinking that went on, and Internal Affairs might have had something to say about the marathon poker game that it fuelled. It was the first time I've had a glass of port since Labour put that ludicrous tariff on it many years ago. Nevertheless, no-one was hospitalised, skipped work or went home and beat their wives.
