Inflation During the Pandemic in the OECD

Inflation is definitely here. The latest CPI release puts the annual inflation rate in the US at 8.5% over the past 12 months, the highest 12-month period since May 1981. That’s bad, especially because wages for many workers aren’t keeping up with the price increases (and that’s true in other countries too).

But what about other countries? Many countries are experiencing record inflation too. The same day the US announced the latest CPI data, Germany announced that they also had the highest annual inflation since 1981.

Using data from the OECD, we can make some comparisons across countries during the pandemic. I’ll use data through February 2022, which excludes the most recent (very high!) months for places like the US and Germany, but most countries haven’t released March 2022 data quite yet.

Let’s compare inflation rates and GDP growth (in real terms, also from the OECD), using the end of 2019 as a baseline. We’ll compare the US, the other G-7 countries, and several broad groups of countries (OECD, OECD European countries, and the Euro area). The chart below uses “core inflation,” which excludes food and energy (below I will use total inflation — the basic picture doesn’t change much).

The Justice Dividend

While I was listening to The New Bazaar and enjoying an episode with Tim Harford, I was reminded that economists don’t just have the job of understanding the world. We have a responsibility to our fellow man of keeping fallacy and economic misunderstanding at bay (a Sisyphean task).  That doesn’t mean that we just teach economic theory. We can and should advocate for good economic policy ideas and try to think up some policy alternatives that fit our political climate.

Here I was sitting, being grumpy at the US Federal deficit, when an idea came to me. I am full of ideas. Especially unpopular ones. So, I especially like ideas that make political sense to me given that the political parties care about their policy values and re-election. Asserting that people in congress actually care about policy apart from re-election is kind of a pie-in-the-sky assertion. But, here we go none the less.

Mancur Olson liked to emphasize the role of concentrated benefits and diffused costs in political decision making. Economists point to it and explain the billion-dollar federal subsidies that go to interest groups. A favorite example is Sugar subsidies. As of 2018 there were $4 billion in subsidies and sugar growers earned $200k on average. The typical family of four pays about $50 more in subsidies each year as a result. The additional tax burden of higher sugar prices is also relatively small. Therefore, says the economist, the few sugar beet and sugar cane farmers have a large incentive to ensure the subsidy’s survival while others pay a relatively small cost to maintain it. That small cost means that there is little money saved and little gain for any individual who might try to fight the applicable legislation.

That’s the standard story. But it’s so much worse than a story of concentrated benefits and diffused costs. The laity don’t know how the world works in two important ways. First, many people will simply say that they are happy to protect American producers for an additional $50 per year. That’s a small price to pay for ensuring the employment and production of our fellow Americans, they say. An economist might reply, in a manner that so automatic that it appears smug, that that $50 would instead go to producers of other goods and that our economy would be more productive if the sugar-producing resources were diverted elsewhere. This is Bastiat’s seen and unseen. Honestly, I suspect that neither economists nor non-economists can adopt the idea without a little bit of faith.

Secondly, people don’t know what causes a particular price to change. Hayek painted this characteristic as a feature of the price system. We are able to communicate information about value and scarcity without evaluating the values of others or the actual quantity of an available resource. However, lacking causal knowledge of prices makes for some bad policies. Say that the subsidies and protections subsided and the price of US sugar declined. The consumer would likely not know anything about the subsidies in the first place, much less that they were rescinded. Further, the world is a complicated place and people are apt to thank/blame irrelevant causes otherwise (corporate greed, anyone?).

When economists blame concentrated benefits and diffused costs, they often assume that there is perfect information. THERE ISN’T. People don’t know how the world works well enough to predict with confidence what will happen in an alternate version of reality without subsidies. Nor do they understand the particular determinants of prices in our current world. Half the battle is a lack of knowledge about the functioning of the world – not just that the costs and benefits fail to provide a strong enough incentive for legislative change.
