Coal, then oil and gas, have driven the mechanization and industrialisation responsible for lifting billions out of agrarian poverty, and all in the space of little more than a century. As a band of miserable misanthropes would have it, oil, coal and gas are an unadulterated evil to be driven back to the earthly depths […]
Penrith, Western Sydney 46C today. CSIRO/BoM projections below show rise in days per year over 40C under scenario consistent with current Aus Gov climate policies (red), compared to cutting fossil fuel emissions to reach 1.5 degree target (green) #auspolhttps://t.co/mjnoLcAhWCpic.twitter.com/sNj4x6GxX6
That comes with no surprise to anyone vaguely familiar with business conditions and the level of official corruption in the former Soviet Union. Russia is a more honest place to do business.
Carbon traders who buy from the Ukraine are not buying an inspection good. An inspection good is a good whose quality you can ascertain before purchase.
They are not buying an experience good. An experience good is a good whose quality is ascertained after purchase in the course of consumption.
What these carbon traders in New Zealand are doing is buying credence goods from the Ukraine. The credence goods are the carbon credits, which the Morgan Foundation and others have found often to be fraudulent.
A credence good is a good whose value is difficult or impossible for the consumer to ascertain. A classic example of a credence good is motor vehicle repairs.
You must trust the seller and their advice as to how much you need to buy of a credence good. Many forms of medical treatment also require you to trust the seller as to how much you need.
Carbon credits are such a credence good. You know there is corruption in the Ukraine and many other countries that supply them. You may never know at any reasonable cost whether the specific carbon credits you buy were legitimate.
The reason why carbon credits are purchased from such an unreliable source is expressive voting. As is common with expressive politics, what matters is whether the voters cheer or boo the policy. The fact whether it works or not does not matter too much.
The Greens are upset about this corruption in carbon trading. They did not mention the corruption in international carbon trading and climate aid when they welcomed the recent Paris treaty on global warming but that is for another day.
Co-ordinated international action on global warming is rather pointless if some of the key countries with carbon emission caps are corrupt, which they are.
As Geoff Brennan has argued, CO2 reduction actions will be limited to modest unilateral reductions of a largely token character. There are many expressive voting concerns that politicians must balance to stay in office and the environment is but one of these.
Once climate change policies start to actually become costly to swinging voters, expressive voting support for these policies will fall away, and it has.
One way to stem that fading support is to buy carbon credits on the cheap and there is plenty of disreputable suppliers of cheap carbon credits. Buying dodgy carbon credits as a way of doing something on global warming without it costing more than expressive voters will pay.
One of the predictions of the adverse selection literature is that if consumers cannot differentiate good and bad goods from each other, such as with used cars, the market will contract sharply or even collapse because buyers cannot trust what is on offer. This risk of adverse selection undermining a market applies with clarity to carbon trading.
