The Profit Problem

Over at naked capitalism Philip Pilkington has a post on profits in a capitalist economy:

We imagine an island. On this island we find a capitalist (or an ‘entrepreneur’ to use more politically correct language), a bank, ten workers and a government. Five of the workers are bakers and five of them are builders. We assume that the capitalist does not consume anything and that there are no input costs apart from the cost of labour. In addition to this capital goods (machines etc.) do not depreciate in value (wear down etc.). Finally, the workers do not save. In other words: they consume all that they earn.

(This seems silly but we can include these variables in more complex models, some of which will be dealt with in more condensed form later. For now let us just say that all this occurs because the island is magic and a wizard created it…).

The capitalist must pay the workers at least $1 a day as the government has a minimum wage law in place. So, the capitalist hires five workers (the builders) to build a bread factory – spending $5. He then hires the other five workers (bakers) to make bread in the factory – spending an additional $5. All of this money is raised from the local bank which charges him a rate of $1 interest a day. The capitalist ends up with a giant loaf of bread which he sells to the workers for all their wages – the bread thus sells for $10 and each worker gets a 10% share.

We must stop here for a moment to highlight an important fact. Note that the overall amount of spending power in the economy – that is, the workers’ aggregate wages – determines the price of the bread. The bread is divided into ten because there are ten workers, but it is the amount they are paid that sets the price of the bread. More on this in a moment, for now we get back to our fairytale.

At this point, the capitalist has a brand new bread factory and his $10 back which, after paying making his interest payment for the day, totals $9. He then hires his five bakers once more at $1 each and bakes another giant loaf. If this loaf were allowed to go directly to market a deflation would result and he would only get $5 for the loaf – with each worker getting a 20% share. This is because the same capitalist, since he already has his factory built, no longer needs to hire the five builders and so only the five bakers are employed. If there were no other actors in the economy these builders would remain unemployed and the aforementioned deflation would result. However, Roosevelt II has just been elected and, being the clever president that he is, he deficit spends to hire the builders to build a road in front of the bread factory – paying the minimum rate of $1 per worker.

At the end of the working day, the builders once more join the bakers at the factory door and, since everyone has received their wages, the bread sells at its previous rate – the capitalist gets $10 (after interest payments he has $9), the workers all get a 10% share of the giant loaf and there is no deflation. This time, however, the capitalist ends up with a tangible profit because the government has taken over the task of investment.

I take the post as an argument that, when you have a fiat currency (as we do), the government shouldn’t borrow the money that it spends in excess of revenues but should simply conjure it out of thin air. That has its own problems but they may well be less significant than those that face us now, largely for doing exactly what he suggests.

As I see it his model has a number of problems:

  • It has internal inconsistencies. For example rather than “a government” the island should have “a king” or “a bureaucrat”. That makes a difference: kings and bureaucrats need to be paid, too.
  • The capitalist never seeks to increase his profits by expanding, making his operations more efficient, or expanding into other areas. Like Scrooge McDuck he just piles his money up in a vault.
  • It ignores deadweight loss.
  • The government has no revenues and has no costs of finance. The only explanation I have for that is that the government is creating the money it spends.
  • Why don’t the builders become bakers?
  • He assumes some of the most contentious issues, e.g. sticky wages.

Ultimately, the most damning thing about his model is that it’s just too steady-state. At every step after the second step (when “the government” steps in to ensure that the builders remain builders but nonetheless don’t starve) nothing ever changes. There are no variable input costs. Every new infrastructure program has exactly the same value as the first. The government bureaucrat, who is now doing more work administering all of those spending programs, never demands a larger share, and so on. It’s a lovely Brussels-hued world.

In the real world, however, roads in front of the bakery are more valuable, whether viewed economically or socially, than bridges to nowhere, there is no particular reason to have the same number of builders forever, capitalists and bureaucrats both consume, too, and governments that overextend themselves whether by borrowing too much, by minting too much money, or by building infrastructure that isn’t really necessary lose the confidence of the people and the whole shebang comes crashing to a halt.

I look forward to criticisms of the model in comments from those better informed than I.

  • I’m not better informed, but IMO that “model” isn’t much better than the underpants gnome model.

  • It ignores the fact that unemployed resources are also an opportunity. This economy has just one good…forever. Why don’t the builders, or some of them, start raising cows. Others making milk into cheese. And so on? New goods and services come, and go, all the time. Why are bakers stuck being bakers and builders builders? Is there some autocratic policy that says, “You are a builder, and can never do anything else, ever…on the pain of death?”

    This is why growth models have depreciation, population growth, and treat the “consumption good” as really being a composite good for all the things we like to consume.

    However, in the steady state in a deterministic growth model yes, you might end up with 5% unemployment, or whatever level, and it will never go away. Ever. You are in the steady state after all. Of course, this raises the question, do we live in a deterministic world? Or one that is better captured by stochastic events? Technology shocks, supply shocks, demand shocks, and even changes in preferences over time?

    Over time after studying economics a great deal, I’ve come to the conclusion that the mechanistic approach to much of economics, while sometimes useful, also misses an important point: the economy is more like a living organism. Seems reasonable to me in that it is comprised, when you get right down to it, of living organisms. This is why I’ve been fascinated with evolutionary game theory in recent years.

    (This seems silly but we can include these variables in more complex models, some of which will be dealt with in more condensed form later. For now let us just say that all this occurs because the island is magic and a wizard created it…).

    TL;DR–For now let us just say the model is stupid.

    Why he had to right all that other verbiage, I don’t know. Maybe he wanted to sound erudite.

    I’d call Pilkington an idiot, but he left himself maneuvering room with his “fairy tale” proviso.

    “Ultimately, the most damning thing about his model is that it’s just too steady-state. ”

    Well, uh, yeah. That’s what the price mechanism is all about. This is usually the point where the left comes in with their horror examples and says “that’s all academic” and wants government intervention for this or that……..without ever realizing its almost always government intervention that disrupts the price mechanism. They don’t want to hear that.

    “Over time after studying economics a great deal, I’ve come to the conclusion that the mechanistic approach to much of economics, while sometimes useful, also misses an important point: the economy is more like a living organism.”

    Exactly. And so what mechanism is it that reflects the constant and inevitable changes in this organism? Wizards in Washington? Their regulations, dictating winners and such? I don’t think so. A bazillion market transactions out there in the good old US of A – pricing.

    BTW – How’s the Chevy Dolt, er Volt, doing?
