Help! Census confusion

I have been trying to figure out the latest census figures, especially for sources of population growth. Does anyone know what I am doing wrong?

I calculated the change in population using the post enumeration survey. I counted up the births and deaths from the vital statistics from Infoshare. The difference should be international net migration. In the 2001-2006 period there was a difference, but a small one.

In the latest census, the gap is really quite large. Implied net migration is around 500 people per year, compared to the data that is normally used for international migration (7,500 per year).

Does anyone know why the difference is suddenly so large? Or what I am doing wrong?

Also, sorry I have been missing in action from the blog. Work has been crazy and I was writing this book to, um, agitate people.

Population growth - between censuses

Can we justify the Easter trading laws?

Back in April, Benje Patterson decided to have a think about whether the Easter trading laws really made sense (Infometrics link).  His view was that:

Having so far failed in my search for a reasonable justification for restricting Easter trading in New Zealand, my mind then turned to a more consumer-orientated motivation that transcends religion and worker welfare.  Perhaps I am the odd one out and the majority of society want the shops to be closed at Easter simply because it allows them to enjoy a quiet day, free of temptations to hit the shops and consume.

Is this the only fair justification – and is it a reasonable justification in of itself?

Football: The injury vs pandering margin

During the World Cup, I keep seeing images like the following.


It is interesting, there is a lot of play acting in the masterful sport that is Football.  It is a pity, as if players just got on with the game we would see longer periods of amazing skill and tactical insights.

Sorry about the outage!!

Hi everyone.  I’m really sorry about the fact the site has been down over the past couple of weeks, we had issues with our old host disappearing!

NZAE 2014 is taking place at the moment, with the details here and the hashtag rolling here.  I suggest using the hashtag for everything remotely economics related for the next couple of days 😉

Next week we will be properly back in action.  If you have any suggestions about things that we haven’t covered, due to being unable to post and generally away, leave them in the comments.  I have a few ideas of my own, but always want more 🙂

On fairy tales

Dawkin’s believes that fairy tells hurt kids.  Update:  It sounds like I have been unfair, here are the reported comments.  It still makes a cool conversation, so I will leave this up for comments about the ideas 🙂

From the article:

The British scientist, known for his assaults on religion in books such as The God Delusion, has told a science festival audience that parents should ditch fairy tales in order to “foster a spirit of scepticism” in their children.

“I think it’s rather pernicious to inculcate into a child a view of the world which includes supernaturalism,” The Times reports him saying.

I find this troubling, as I have a different view on what fairy tales are:

You may note some similarities in this to how I have broadly discussed economics.

However, I’m interested in your thoughts.  Is the framework I’m using “right”, if not why, if so how can we use that to analyse the efficacy of fairy tales for helping give children knowledge (vs misleading them).  Given all this, what lessons can we take for economics!

Some links for today

Hello all.  Here are some links I’d like to do posts on, but don’t have the time.  As a result, I suggest enjoying them for yourself!
