In the news cycle of late: lorry driver shortage threatens empty supermarket shelves.

One product so affected is apparently bottled water. I can say I have been having trouble buying the particular brand of bottled soft water I put in my coffee machine to avoid having to descale it so often.

The Road Haulage Association wrote to the Prime Minister with five causes of the shortage: covid, Brexit, retiring drivers, a driving test shortage and IR35. The first two are causing foreign drivers to return to their home countries, not to return, they say. The last two I imagine are exacerbating the first three. If you make lorry driving pay less and cost more (whether obvious monetary costs or by increasing bureaucratic hurdles) it stands to reason that supply will diminish. To get supply back to the same level, you will have to pay more. In macroeconomic terms: taxes and regulations reduce economic growth. This is how that looks in real world terms.

IR35 is particularly egregious. A driver recruitment agency writes:

The effect of the IR35 reform is to force agency workers who previously operated as Ltd Companies to pay more tax and their agencies or end clients to pay Employer NI Contributions. If we were to keep the drivers’ net income the same, it would result in an increase in employment costs of 25% to the agency.

Maybe they are exaggerating their own costs, but the exact number does not matter too much. More tax is being collected from the employment of lorry drivers: that is the point of the IR35 regulation. One way or another it will be paid for by people directly and indirectly using the services of lorry drivers. Someone might argue that prior to IR35, the haulage industry was immorally getting away without paying enough tax, but that someone must now accept the increased costs of certain goods, including to poorer people for whom such goods are a more significant portion of their income.

Increased barriers to immigration are also said to play a part here. It is undoubtedly true that increased immigration drives down wages as it increases supply, which is to say it drives down the cost of hiring lorry drivers, and drives down costs to everyone who is indirectly using their services. Quite possibly the remaining lorry drivers are happy about this shortage (although I do suspect that any thus increased earnings are just going towards the now higher taxes). Also happy are the people who want everyone to have higher wages and use terms such as “living wage”, even if (as I suspect) those people also want more freedom of movement without wanting any reduction in wages that comes with it.

In the long term, more immigration should not mean lower wages: there is no lump of labour; if there are more people then there is more work to be done. On the contrary, denser concentrations of people create efficiencies that decrease costs, which makes things cheaper, which is the same thing as increasing wages. But dynamics are often overlooked. If you suddenly reduce the supply of lorry drivers you are going to suddenly increase the price of them. All of the other effects take time. And some of those effects will be cost-cutting innovations that reduce the need for lorry drivers. So watch out, lorry drivers.

I am a computer programmer. There was a time when there were suddenly many computer programmers arriving from Europe. My wages did not go down. The increased supply of programmers meant that more projects were started, there were more interesting things to work on, more interesting people to work on them with, and in general much more opportunity. Now it is becoming harder to hire programmers. I suspect if this continues, a lot of projects will happen in places where it is not so hard to hire programmers. My wages will not go up. The equivalent problem for the lorry drivers might be that as things get more expensive, people buy less things. Everything gets less interesting. That is how economic decline looks and it will not be good for the remaining lorry drivers in the end.

I have my doubts about whether the shortage will become a real crisis. So far, supply chain crises as a result of Brexit and covid have proved remarkably short-lived, and supply chains remarkably robust. Some new equilibrium will be found. But relative costs do change, and the people who want higher taxes, more regulation, higher wages or less immigration, ought to have the downsides of their demands pointed out to them.
