Subsistence fund the heart of economic growth


What characterizes the modern economy is its complex structure of production that seemingly generates an endless amount and a variety of goods.  It seems that the production structure has, as it were, a self-generating mechanism (i.e. it has a life of its own). Careful examination, however, shows that without a key ingredient, the entire infrastructure could not have emerged. The ingredient that makes it all possible is the subsistence fund. The following simplified example will allow us to ascertain the essence of this fund.

The basics of the subsistence fund

To maintain life and wellbeing, man must have at his disposal an adequate amount of final consumer goods. These goods, however, are not readily available – they have to be extracted from nature. Without tools at his disposal, man can only secure from nature very few goods for his survival.


For instance, take an individual John, stranded in a forest. In order to stay alive, he can only pick up some apples from an apple tree. Apples are the only good available to him that can sustain him. Let us say that by working 20 hours a day, he manages to secure 20 apples, which keep him alive. The 20 apples that John has secured from nature is his subsistence fund, which sustains him.


Being a sophisticated individual, John realizes that if he had a special tool this would allow him to become more productive. His daily production of apples could be 40 apples (i.e. double his current production). The problem, however, is that the tool is not available – it must be made. To make the special tool requires two days of work. If John were to decide to make the tool, he would have a problem. By spending his time on making the tool, he would not be able to pick up the apples that are required to keep him alive.


The only way out of this predicament is for John to put aside an apple a day for the next forty days. By saving an apple out of his daily production and enduring hunger, after forty days he will have an adequate stock of apples that will sustain him while he is busy making the tool. (We make the unrealistic assumption here that apples can be preserved in edible form for forty days to illustrate the importance of saving). Thus, after forty days, John’s subsistence fund will be comprised of 40 apples, which will see him through while he is making the special stick. We can see here that the saved or unconsumed 40 apples enable the making of the tool, which raises the production of apples and lifts John’s living standard.


Let us slightly alter the previous example and introduce an individual Rob who specializes in making these tools. Because he is an expert in tool making, it takes him only one day to make the special tool that John requires. Rob also has to have 20 apples a day to keep him going. Note that rather than saving 40 apples John needs to save only 20 apples now, which will enable him to hire the services of Rob.


Observe that John’s saved 20 apples sustain Rob the toolmaker, while John is maintained by the current daily production of apples, which is also 20 apples.


Note that the making of the tool is a burden – John has to make a sacrifice and save 20 apples thereby endangering his health and wellbeing. However, after 20 days he will be able to use the tool, which will allow him to double his production of apples. If he continues to consume 20 apples a day, this will allow John to increase his subsistence fund.


Thus on the first day, his subsistence fund will be 40 apples, of which 20 are allocated for consumption and 20 are saved. On the second day, his fund will comprise of 20 saved apples + 40 apples from current production i.e. his fund is 60 apples of which 20 is consumed and 40 are saved. On the third day, his fund will be 80 apples (i.e. 40 apples from the daily production and 40 from savings). Out of this John consumes 20 apples and saves 60 apples etc. As the subsistence fund expands, this allows John to hire the services of other individuals that can maintain and enhance his production structure, and thereby raise further the production of apples.


The state of the subsistence fund determines the quality and the quantity of various tools that can be made. If the fund is only sufficient to support one day of work, then the making of a tool that requires two days of work cannot be undertaken. The size of the fund sets the limit on the projects that can be implemented. It also means that the size of the fund determines so-called economic growth. (As the fund increases this permits a greater production of apples).


On this, Richard von Strigl wrote:

Let us assume that in some country production must be completely rebuilt. The only factors of production available to the population besides labourers are those factors of production provided by nature. Now, if production is to be carried out by a roundabout method, let us assume of one year’s duration, then it is self-evident that production can only begin if, in addition to these originary factors of production, a subsistence fund is available to the population which will secure their nourishment and any other needs for a period of one year……..The greater this fund, the longer is the roundabout factor of production that can be undertaken, and the greater the output will be. It is clear that under these conditions the “correct” length of the roundabout method of production is determined by the size of the subsistence fund or the period of time for which this fund suffices.[1]

The essence of the subsistence fund, which we have established with respect to an individual, John, can be widened to include many individuals that trade with each other. John, who produces apples, can now secure meat and clothing from other individuals. This means that the subsistence fund now comprises of a greater variety of final goods ready for human consumption. According to Bohm-Bawerk:

The entire wealth of the economical community serves as a subsistence fund, or advances fund, and, from this, society draws its subsistence during the period of production customary in the community.[2]

Note again that the improvement in the infrastructure is what sets in motion economic growth. The improvement in the infrastructure in turn can take place only as a result of the increase in the subsistence fund. Hence, anything that weakens the subsistence fund undermines the prospects for economic growth.





The subsistence fund and money

The introduction of money does not alter the essence of what the subsistence fund is. Various producers who have exchanged their produce for money can now exchange their money for various consumer goods i.e. they can access the subsistence fund whenever they deem this to be necessary. Observe, when an individual exchanges his money for goods, all that we have here is an act of an exchange and not an act of payment – money is just the medium of exchange.


Payment is always done by means of various goods and services. For instance, a baker pays for shoes by means of the bread he produced, while the shoemaker pays for the bread by means of the shoes he made. (Both shoes and bread are part of the subsistence fund as they are final consumer goods).  When the baker exchanges his money for shoes, he has already paid for the shoes, so to speak, with the bread that he produced prior to this exchange.


Intermediate Goods

If the subsistence fund comprises of final consumer goods, how does a producer of an intermediate good, like a producer of tools & machinery contribute to this fund?  An individual who exchanges his money for the tool will employ the tool in the production of final consumer goods or in the production of intermediate goods that, in turn, will contribute to the production of final consumer goods sometime in the future.


The producer of the special tool, or a producer of any intermediate good, does not directly supply final consumer goods. However, he does offer a means to secure these goods. Additionally, he also offers time.


According to Rothbard:

Crusoe without the axe is two hundred fifty hours away from his desired house; Crusoe with the axe is only two hundred hours away. If the logs of wood had been poled up ready-made on his arrival, he would be that much closer to his objective; and if the house were there to begin with, he would achieve his desire immediately, he would be further advanced toward his goal without the necessity of further restriction of consumption.[3]


In addition, with the introduction of more advanced tools and machinery various new consumer goods can be produced, which prior to the making of these new tools were not available at all to individuals. Obviously, if the tools and equipment acquired turn out to be useless, then the savings of purchasers of these tools and equipment are squandered.


Saved final consumer goods that were transferred to the producers of tools and equipment are therefore simply consumed by them and they make no contribution to the subsistence fund.  We could also say that the production of useless tools and equipment weakens the subsistence fund.


How about services such as medical services? Or what about things like providing education or the services offered by music and other arts? Should we include them in the subsistence fund? We suggest that without the availability of final consumer goods– that sustain human beings – various services such as art and medical services cannot be generated. (Various individuals that provide these services must be also sustained).  Once, people’s living standard increases all these things become affordable to human beings.


Monetary expansion and subsistence fund

When money is created out of “thin air” it leads to a weakening of the subsistence fund. What is the reason for this? The newly created money sprang into existence out of “thin air” so to speak. The holder of the newly created money can use it to withdraw final consumer goods from the subsistence fund with no prior contribution to the fund. Hence, this act of consumption, or non-productive consumption, puts pressure on the fund. (The consumption is non-productive because the individual consumes goods without contributing to the subsistence fund).


We can infer from this that when money is generated out of “thin air” it diverts the means of sustenance away from wealth producers who have contributed to the subsistence fund towards the holders of the newly created money. For a given subsistence fund this will imply that wealth producers will discover that the purchasing power of their money has fallen since there are now less goods left in the fund.


As the pace of money creation out of “thin air” intensifies, it puts more pressure on the subsistence fund. This in turn makes it much harder to implement various projects as far as the maintenance and the improvement of the infrastructure is concerned. Consequently the flow of production of various final consumer goods weakens, which in turn makes it much harder to make provisions for savings.


All this in turn further weakens the infrastructure and so undermines further the flow of production of final consumer goods. Note that without the maintenance of the infrastructure its ability to generate final consumer goods is going to weaken.


The maintenance of the infrastructure requires the allocation of savings towards various individuals that maintain the infrastructure. In our example with the tool if John will not add more tools to his inventory at some point the tool will break and the production of apples will halve. In order to have more tools in his inventory John would have to allocate savings for this.


We can thus conclude that contrary to the popular way of thinking, monetary growth cannot produce general expansion in economic activity. On the contrary, by diverting the means of sustenance from wealth generating activities towards non-wealth generating activities monetary expansion only weakens economic growth.


Loose monetary and fiscal policies, which aim at growing the economy, are in fact achieving the exact opposite. As long as the growth rate of the subsistence fund stays positive, this can continue to sustain productive and non-productive activities. Trouble however erupts, when, on account of loose monetary and fiscal policies, a structure of production emerges that tie up much more consumer goods than the amount it releases. (The consumption of final consumer goods exceeds the production of these goods).


This excessive consumption relative to the production of consumer goods leads to a decline in the subsistence fund. This in turn weakens the support for individuals that are employed in the various stages of the production structure, resulting in the economy plunging into a slump.


Once an economy falls into a recession because of a decline in the subsistence fund, then any government or central bank attempts to revive the economy is going to fail. Not only will these attempts fail to revive the economy, they will deplete the subsistence fund further, thereby prolonging the economic slump.


The shrinking subsistence fund exposes the erroneous nature of the commonly accepted view that loose monetary and fiscal policies can grow an economy.


We suggest that the policy ineffectiveness is always relevant whenever the central authorities are attempting to “grow an economy”. The only reason why it appears that these policies “work” is because the subsistence fund is still expanding.


On this Mises wrote,

An essential point in the social philosophy of interventionism is the existence of an inexhaustible fund which can be squeezed forever. The whole system of interventionism collapses when this fountain is drained off: The Santa Claus principle liquidates itself.[4]


Summary and conclusions

Most individuals in the western world take the ample availability of goods and services for granted. Indeed, the complex structure of production gives the impression that what is required is simply the existence of demand and the rest will follow suit.


We suggest that the sophisticated structure of production, which generates seemingly unlimited goods and services, does not have a life of its own. In order that the production structure can continue to supply the great quantity and variety of goods, it requires a key ingredient, which is the subsistence fund. It is this fund, which not only maintains, but also enhances the production structure and thereby promotes people’s lives and wellbeing.
