Alcohol regulation: economists would do it better

/23 Comments/in , /by

The NZ Law Commission is on the way to cutting back on the availability of alcohol. Their justification is twofold:

  1. The contribution that excessive use of alcohol led to law and order problems in the country.
  2. The serious health and injury effects from alcohol consumption, as well as a list of other social harms.

And the principle they used to weigh these issues: harm minimisation. What, you say: What about weighing the benefits? What indeed! Eric Crampton takes to the second point of the report thoroughly:

The study counts as costs reduced labour productivity. … If we only count costs, then these get included: costs to society via lost output and costs to the government via reduced tax revenues. But if we worry about NET costs rather than gross costs, these have to disappear. Why? Because if I decide to drink and be less productive at work, I’m less likely to get a promotion or a salary increase. My productivity affects my wages. If I decide to be less productive and have a lower expected salary path, that’s between me and my employer: I’m bearing the costs. If I decide to do it, that’s prima facie evidence that I weigh the benefits as greater than the costs.

Not only do they miscount costs, but they also fail to take into account any net benefits: the enjoyment of drinking, or the higher salaries that come with it. Read more

Framing farts

/1 Comment/in /by

Cognitive Daily reports that the study of framing is alive and well, although possibly in the running for an IgNobel Prize:

A team led by Simone Schnall asked students walking outside on a college campus to answer questions about scenarios like this, rating them on a scale of 1 (extremely immoral) to 7 (perfectly okay). The catch was that they had rigged a trash can near the experimenters’ desk with fart spray. Some respondents read and rated the stories in the presence of a mild stink (four sprays of fart scent), some had a strong scent (eight sprays), and a lucky third group completed the experiment with no scent at all. Here are the results:

Scary fact(oid) of the day

/7 Comments/in /by

OK, so this sounds a little incredible to me, but it’s in The Guardian so it must be true, right 😛

Shipping by numbers

The world’s biggest container ships have 109,000 horsepower engines which weigh 2,300 tons.

Each ship expects to operate 24hrs a day for about 280 days a year

There are 90,000 ocean-going cargo ships

Shipping is responsible for 18-30% of all the world’s nitrogen oxide (NOx) pollution and 9% of the global sulphur oxide (SOx) pollution.

One large ship can generate about 5,000 tonnes of sulphur oxide (SOx) pollution in a year

70% of all ship emissions are within 400km of land.

85% of all ship pollution is in the northern hemisphere.

Shipping is responsible for 3.5% to 4% of all climate change emissions

Whoah!!! So, if countries start introducing carbon trading, will the ships be covered? Unless the oil producing nations sign up I guess that they’ll still be able to get untaxed fuel and they can always sail under the flag of a country that doesn’t care. Can anything be done about them (presuming stuff gets done about any climate change)?

It’s just hype

/1 Comment/in /by

I used to be a fan of The Hype Machine, but then I started to feel like the music on it was more hype than substance. People often wonder about how much of the talk about current music ‘sensations’ is hype and how much truth there is to there brilliance. So I was fascinated to read Gene Expression’s analysis of hype vs worth for artists and classical composers. Apparently Monet and Brahms are waaaaaay over-hyped and actually their chops aren’t that great! It turns out that composers are pretty decently valued according to their accomplishments, but some artists are over-hyped. The data also shows that we have a love affair with late 19th century art and music that scholars just don’t understand. Check out the posts cos it’s fascinating stuff if you’re a data geek 🙂

Hangovers, Nurofen and product differentiation

/17 Comments/in /by

In my horribly hungover state, the first thing I did when I got to work this morning was go looking for pain relief. Excellent, I thought, there is some Nurofen in the cupboard. My initial exuberance was soon allayed as I saw we only had Nurofen ‘Back Pain’ medication, not what I was after, while the Nurofen ‘Migraine Pain’ packet was cruelly empty. A closer inspection of the packets, however, revealed the two contained exactly the same ingredients!

More quality quotes from the civil service

/1 Comment/in , /by

As if they were inspired by yesterday’s post – some civil servants from Housing New Zealand dropped this train of thought:

The submission said listing housing projects as nationally significant would help prevent the delays and extra costs caused by objections from neighbours – “a situation commonly referred to as NIMBY [not in my backyard] opposition”.

So the government should be able to force projects through without regards to the impacts on individuals they aren’t interested in – doesn’t sound like social welfare maximising policy to me.

At least National came out and said this was a bridge too far. Seriously though – where the hell do some of these people get off talking like this. Do they not listen to what they say …
