Why Taxes Trump Subsidies

My last post explored the inefficiencies in the primary objective of the Clean Energy and Security Act bill, mainly carbon-offsetting. This post will focus on the other provisions in the bill, mainly, subsidies in the form of tax credits and business grants for those entities choosing to use clean energy technologies.

I must preface that though I am criticizing the abilities of this bill, it is a monumental legislative step in the right direction; though it must still pass in the senate. A friend of mine who does not believe in global warming has even expressed admiration for the bill and its intentions, though agrees with my assessment of its planned execution of those intentions.

The US government has long suffered from control issues. This bill provides subsidies and tax credits for those people who choose to use energy efficient technologies. To understand why this is not a great idea, we must look at the effect subsidies have on decision-making and rationality. In economics, we assume that people are rational agents acting on perfect information, among other things. If information is perfect, then prices represent the actual cost of the goods produced. By subsidizing clean energy technologies through business grants or tax credits the government is essentially creating prices that do not reflect the true social value of the good. Therefore, more is consumed of these goods than would otherwise be optimal and creates a higher social net cost without the same social net benefit that would have occurred if the prices were representative of the value of the good.

So what would be the solution? Instead of making it cheaper to consume certain energy sources, make it more expensive to consume the bad energy technologies. This may seem to achieve the same objective of having consumers substitute good energy with bad but this results in a more socially optimal solution.

Bad energy goods are labeled “bad” because they create an externality and further, this externality is not internalized in the price. This means that the cost to society of using this good is higher than the price being charged by firms because the firms are not held responsible for the negative effects the result from production and use of the good. By increasing the cost of these bad energy goods we can internalize the externality caused by the goods.

Why is this better? This gives consumers perfect information by way of prices so that they are able to choose the socially optimal level of consumption of both, or just one, good(s). The problem with subsidizing goods is that it gives signals to the consumer that the good creates a positive externality, i.e. it increases social welfare. While clean energy technologies trample less heavily on the earth, solar panels and wind turbines must still be produced by a firm using hazardous materials and non-renewable energy. One cannot argue that using such technologies reverse damage in the atmosphere, they only damage it less; therefore, they do not create a positive externality and should not be subsidized.
