California Gets Carbon Tax Horribly Wrong

Unfortunately, I need to explain some economics before understanding why this California politician is clueless.

A market externality is a cost of a good or service that is not included in the price. For instance, I am a power plant and do not figure in the cost of acid rain when I burn coal to generate electricity (luckily we have ways to remove the sulfur from the emissions now, but think back to the 80s). The cost of the acid rain is the market externality.

A social cost or a social good is part of the market externality. In the example above, acid rain is a social cost. Since the cost of the acid rain isn't figured into the price, the difference is borne by everyone affected -- hence the social cost. A social good is similar, but a desired result. For instance, a well-educated population is a social good even for those who did not pay tuition.

A pigovian tax is a "tax" added to the price of a good or service which has an external component. Or think of it as having a social cost. The pigovian tax is meant to bring the price in line with the true price -- it attempts to internalize the externality. The result is two-fold: (1) the behavior causing a social cost is disincentivized, so less social cost and (2) the price now reflects the true price which increases market efficiency.

When it comes to carbon emissions, market externalities are the true problem. The actual cost of emitting carbon (via climate change mainly) is ignored. Gas is cheaper than its true price would be. It's impossible to know exactly what the true price would be, but that doesn't mean it doesn't exist. So the best way to solve carbon emissions that contribute to climate change is through a pigovian tax. More on this in the forthcoming issue of the Journal of Lutheran Ethics.

So when I saw an article about carbon tax in California I thought they were on the right track. But then I read the full headline: "California senate leader: Carbon tax would return revenue to poor, transit." A pigovian tax can't be treated like a sales tax or income tax. It can't simply be thrown into the revenue barrel and allowed to be porked out like the rest. The whole point of a pigovian tax is to bring the externality into the market and reduce social costs to equal or less than zero. Simply doling out this revenue to the poorest Californians does nothing to mitigate climate change. The proceeds should be used for the social goods that help neutralize carbon emissions. While I doubt California is interested in paying Brazil not to cut down the rainforest (a truly important measure to take), I think they would be interested in a research grant for tech companies to look into artificial carbon sinks. The revenue from this tax could help fund such a grant. While they also mention public transit, I just hope they do it the right way in order to reduce traffic instead of increase it. See David Owen's great books which cover, among other topics, induced traffic.

Martin Luther Was Not Against Capitalism

I've recently read more than one article that paints Martin Luther as anti-capitalist. They offer quotes from Luther's writings pointing to his critique of (what they call) free markets.Granted, the articles at times used "emerging" and other such nuances.  This still irked me. Not because I am in love with our current flavor of capitalism (I am not), but because it shows how many Christian ethicists need a better background in economics.

Martin Luther died in 1546. That's the first reason why Luther never wrote against capitalism. It simply didn't exist during his lifetime. I'll grant that pinning a birthdate on an emergent economic order is impossible, but 1546 is nowhere close. Adam Smith's Wealth of Nations was published in 1776. Again, you can't date an emergent order on a book's publishing, but Wealth of Nations had such an effect on economic practice that it is difficult to ignore. So Luther died a full 230 years before Wealth of Nations.

But surely the emergent order that Smith described was in an inchoate form for many years preceding Wealth of Nations? Most assuredly. So let's look at exactly what these articles have used to portray Luther as anti-capitalist. The main quote I'd like to address is here:

“Daily the poor are defrauded. New burdens and high prices are imposed. Everyone misuses the market in his own willful, conceited, arrogant way, as if it were his right and privilege to sell his goods as dearly as he pleases without a word of criticism.”

This sounds like a resounding critique of free markets. Except that would require an anachronistic stretch. Free markets did not exist in Luther's time. Markets certainly did, but they weren't free. They were plagued by cartels, price fixing, collusion, and similar activities that would now be considered fraud (though given the lack of prosecutions from the financial crisis, they were probably to this day get off scot free). The economy of Luther's time and place was dominated by the Fuggers. Monopoly does not make for free markets either. So we can't read Luther's comments to mean he was against free markets or capitalism. We can certainly say he was against exploitation of the poor, though. That would be a great anchor on which to base an article. But it wasn't.

Luther is certainly critiquing a market, but not a capitalist free market. He's critiquing the market of his day and region. We would be silly to universalize these comments as a critique of capitalism or free markets in general.

This bias, though, isn't limited to Christian ethicists writing about economics. I see similar problems in what economists are writing about Uber -- the surge pricing taxi service. Economists are praising uber like it's the best thing since comparative advantage. Yet they don't realize that Uber, by itself, is not a free market tool. It is a monopoly. My state representative recently tweeted:

To which I replied:
If the question is "What would Martin Luther think of our contemporary flavor of capitalism?" the best answer is "I don't know." I would presume to put words into his mouth. I'm pretty sure he wouldn't like it. But it would be for different reasons than those given in the articles mentioned.
