Why I’m jealous of my eldest son

In his recent blog-post The pillars of tax wisdom, Tim Harford (author of The Undercover Economist) discusses “James Mirrlees — now a Nobel laureate — who tried to figure out what could be said about optimal income taxation. One of his conclusions, surprising to him as much as anyone else, was that an optimal income tax might impose flat or even falling marginal tax rates.”

Osborne’s spending review

So what do we all think?

My, and my wife’s, submissions on the NHS Agenda

Another day, another attempt to slow our government’s dismantling of everything of value in this country. Yesterday it was freedom of information, the day before it was the BBC; today it’s the NHS.

Yes. I was iterating through the keys in a HashMap to find out whether the one I wanted was there. But the whole point of a HashMap is that looking up a key is an O(1) operation.

What I should have written is:

if (map.containsKey(eventName)) {
  m.handle(eventName, data);

The moral of the story: I can be really, really dumb. (But hey, at least my code worked!)

How to measure the strength of the economy, redux

Last month, I argued the point (admittedly at rather more length than necessary) that GDP does not measure what we’re interested in. I’m currently reading Tim Harford’s fascinating book The Undercover Economist [amazon.com, amazon.co.uk] — which, by the way I highly recommend — and I was pleased to discover that he agrees with me.
