As I drove through France and Spain on my holiday, I thought about the tolls one must pay (on most) motorways. I was thinking how do they set the prices of these tolls? Of course, public infrastructure like motorways is often now financed by a combination of public and private investment. Regardless of the investment type, can you imagine how tricky it is to pitch a price for a motorway toll. If it’s too high, less will use it (M6 Toll in the UK) and costs take much longer to be recouped. Set it too cheap and it floods with traffic, which in turn eventually results in less users, and that equals less money. Should the price be set with future investment and on-going maintenance in mind. Should it be a social good with a very low price – but then where will the money come from for re-investment? Lots of questions here, but I hope you can see a lot of management accounting is behind these decisions. I would imagine getting the initial price correct is the toughest part. Nowadays though, I am sure there are plenty of modelling tools to help toll operators and governments.
According to an article in Time (April 18, 2011), a lot of money can be saved by retro-fitting old buildings. I have written a few posts already about this, but this article gives some really good examples of the kind of money that can be saved from some relatively simple initiatives. According to the article, older skyscrapers are one of the worst type of buildings in terms of energy efficiency. Some investment in lighting, heating and insulation can make a huge difference to costs and energy efficiency. For example, the Empire State building spent $13m in 2010 on a retrofit. The result is a 38% decrease in utility bills and a payback period of less than three years. Another example is a re-fit of a federal building in Cleveland, which saves $600,000 per annum. The city of Melbourne, Australia is also mentioned. The city’s Lord Mayor sums up well – “this is not some feel-good environmental initiative. It is a hard-headed economic business decision.
