Aight Dave, it’s your turn:
So it would seem that our discussion comes down to two issues: Say’s law and the efficacy or lack thereof of government policy in theory (neither of us denies that in practice it’s gonna f*** up)
Say’s Law
Now forgive me, because this is going to be a bit of a tangent, however it may clarify my position.
In Human Action three very important things that Ludwig Von Mises talks about are:
A: The tendency of classical economists to conflate the functioning of the barter and money economies. They act similarly in some ways, but differently in others.
B: (As an extension of this) The ability of changes in the money supply to have real affects on the economy. For instance much of the work Mises does with inflation in the book deals with how the creation of money does alter business behavior and does redistribute wealth and spending in the long run.
C: The need to incorporate real factors into praxeological theorems. If we apply this to Keynes then we can interpret Keynes’ work as trying to take economic theory away from some unrealistic classical assumptions. This is why I sympathize with Keynes even though I disagree with him, and much of my sympathy comes from the spirit Mises is embodying above. Indeed in this same vein the following quote from that part of the general theory I read really stuck out to me:
“Obviously, however, if the classical theory is only applicable to the case of full employment, it is fallacious to apply it to the problems of involuntary unemployment—if there be such a thing (and who will deny it?). The classical theorists resemble Euclidean geometers in a non-Euclidean world who, discovering that in experience straight lines apparently parallel often meet, rebuke the lines for not keeping straight—as the only remedy for the unfortunate collisions which are occurring. Yet, in truth, there is no remedy except to throw over the axiom of parallels and to work out a non- Euclidean geometry. Something similar is required to-day in economics. We need to throw over the second postulate of the classical doctrine and to work out the behaviour of a system in which involuntary unemployment in the strict sense is possible.”
Now I have heard from multiple sources that Keynes stramanned Say’s law, and from what I have read of his opinion on that subject it would appear to be the case if only because he grazed over the issue, however, it would appear that this isn’t necessary. Let’s apply Mises’ own insights outlined above to some of the defenses made for Say’s Law above.
“The same principle leads to the conclusion, that the encouragement of mere consumption is no benefit to commerce; for the difficulty lies in supplying the means, not in stimulating the desire of consumption; and we have seen that production alone, furnishes those means. Thus, it is the aim of good government to stimulate production, of bad government to encourage consumption.”
Now once again, the fundamental issue concerning Say’s law is this: Can monetary demand cause an increase in production? To me the answer would seem to be a resounding “yes”. This is ultimately because, as we both agree, businesses run and labor works to make money. If the goods aren’t there to immediately back up the money then firms make profits in the short run and will increase output if they can. Just as a brief example, let’s say that a hot commodity that a lot of people by is Snood. We increase the money supply and give some people a lot of money. Well the demand for Snood has just gone up. Because the prices of inputs won’t rise until demand has increased, there is a brief period during which Snood can buy more inputs and increase production. Thusly an increase in demand, unbacked by an immediate increase in production, will spur production. Do you believe that the laborers making Snood will refuse the increase in their paycheck because production hasn’t increased? In the short term their real buying power increases because all prices in the economy haven’t adjusted yet.
What is the problem with what I am saying?
So for instance when you state
“So if we are to tackle the problem of lack of demand, we must do it by making it possible for people who cannot demand now to be productive so that they can demand.”
All that is needed for one to demand in the moneyed economy is for one to have money. So if we give him money then he can indeed demand.
“Say’s law proves that there cannot ever be a surplus of demand over production. Even Keynes admits that. His only quibble was that demand might be less than production in the aggregate, or so he thought.”
Once again, I don’t understand this. If we increase the money supply then demand for goods in general rises, if only nominally. So long as prices don’t rise immediately there will be a real increase in demand. What do firms do when demand rises ceteris paribus? They produce more. If resources are relatively well employed then bidding between firms will quickly bid up prices and production in general will end up approximately back where it started. If resources are relatively unemployed, however, then a sustainable increase in output is possible.
Part of the reason I bring up barter is this: In the barter economy you must produce before you can consume exactly because you trade good for good. There is no way to spur demand without spurring consumption, however in the moneyed economy demand exists as a result of money, therefore money demand can be stimulated by increasing the availability o money.
On the matter of government and aggregate demand:
“If the problem is that the manufacturers lack purchasing power, and we have to give it to them, that can only be done by taking away purchasing power from someone else. So that aggregate purchasing power is not increased by govt taxing or spending.”
I disagree with this because if there are a large deal of idle resources then inflation won’t occur with an increase in the money supply (up to a point). As we both know the causal factors that lead to inflation include bidding over resources in response to the new nominal demand for goods.
“Maybe we are talking about some scenario where working people have just enough to buy what is made, and want it, but there is a pool of unemployed who cannot buy anything. And no one will hire them, because wages are too high and will not go down ever. This would be Keynes scenario of a frozen situation where the economy is not in equlibrium [= full employment]. So if the govt put in an order for more cheese, the cheesemakers would hire the unemployed to make cheese, even though they are asking for too much money, and every day they work is a net loss for their boss. I don’t understand how this is possible.”
You said you were tired when you were writing this. Government demand on the market is treated the same as demand by anyone else by the firms involved. If the government offered the cheesemaker enough money then he would indeed hire the unemployed and produce cheese.
“Now I think about it, if wages are sticky and too high, that means by definition of “too high” that someone who employs the unemployed at the wage they insist on will lose money every day they are working for him. How can all the taxes and govt spending in the world change that, or convince the employer to hire people so that he can lose money every day?”
In conjunction with what I said above it’s important to remember what is called the “tax multiplier” in modern macro. It’s not an unrealistic assumption that some amount of income is not spent, so if we think of Y as total spending (income=expenditures) Y=C+I+G. C=a+b(Y-T) (a can be zero and this still works) where b is the MPC and (Y-T) is disposable income then we see that, because a portion of income is saved, Y will be increased if we increase T and then move all that spending into government spending then we have effectively increased demand and overall income. I’m blanking on the exact algebra here, but it comes out to state the tax multiplier (the amount y increases as a result of an increase in taxes and a proportional increase in spending) is exactly 1. Y increases by the same amount as T and G. Let’s go back to the cheesemaker.
Now let’s say that people will spend 50 dollars on cheese if their total income equals a thousand dollars and that it doesn’t matter who recieves this income, they will in total buy 50 dollars in cheese (yea I know I’m treating people as automatons but we’re talking about AD which is a fallacious and aggregate in the first place and we’re dealing with a micro example for a macro issue). Now if the government comes along and taxes people for 100 dollars of income and then spends that income on cheese, then the demand for cheese has gone up by a hundred dollars and the cheesemaker will increase his demand for labor and inputs accordingly (once more we’re working on the idle resources/sticky wages assumption). Because the total of 100 dollars will be spread out amongst the populace over this period and their total income will rise once more to a thousand dollars, then private demand for cheese will once more be 50. Therefore we have increased demand by increasing taxes. Demand is now 150 where it was previously just 50.
Now I’m not defending the MPC, but the basic idea here should be fairly clear. Because demand increases by the amount of taxes and overall private sector income is inevitably increased back to the old amount, real AD has been stimulated by tax/spending increase. This is a simplistic model for sure, but to claim it could never function to some degree is foolish.
“I always heard that Keynes solution to sticky wages was to print money to reduce the purchasing power of the currency, and thus reduce the real wages [= purchasing power] of labor, even though they will stay the same nominally. I grant that I am not familiar with the intricacies of his proposals. Did he have some ideas of how to convince employers to lose money willingly?”
I’m in the same boat that you are in terms of a general understanding that Keynes believed this while never actually reading this. However this would not cause firms to lose money, but rather for real wages to fall. Firms would pay according to new demand, while paying workers at the old wage. It makes sense for the firms to do this ceteris paribus. The question is then; does it make sense for the workers?
I feel I answered 7. plenty of times above.
Any feedback would be appreciated. Say’s law in particular is something that I seem to be criticizing too easily to have a real grasp on it.
Also, sorry this ended up so long. My fingers tend to type freely as well. Don’t feel the need to necessarily address everything I say. My major points are
-
Increasing money income will almost always result in an increase in real demand since firms function to make money and labor to buy goods. This differs from the barter economy
-
Government can theoretically increase demand through fiscal policy because the income taken away from the private sector is put back into it while increasing demand for goods and the ability for firms to hire.
The reasons are elaborated to no end above.
