Does Demand Create Supply? | Mises Institute

By popular thinking, increases in demand cause economic growth. According to such thought, whenever the economy falls into a recession what is required is to strengthen demand. Since government is seen as an important part of total demand, what is then required is to increase government outlays, thereby lifting overall demand and hence increasing economic growth.

According to the popular view, it is also possible to strengthen overall demand through the inflationary increases in money supply. With more money in their possession, and for given prices, the so-called real balances will increase and this, in turn, will strengthen individuals’ expenditure on goods and services. This allegedly will strengthen the economy’s overall demand and will strengthen economic growth. A decline in the prices for a given money supply will also boost the real balances and thus the economic growth. But does it make sense that demand is the key driver of the economy?

In the free market economy, wealth-generators do not produce everything for their own consumption. Part of their production is used to exchange for the products of other producers. Hence, in the free market economy, production precedes consumption. This means that something is exchanged for something else. This also means that an increase in the production of goods and services sets in motion an increase in the demand for goods and services. According to David Ricardo,

No man produces but with a view to consume or sell, and he never sells but with an intention to purchase some other commodity, which may be immediately useful to him, or which may contribute to future production. By producing, then, he necessarily becomes either the consumer of his own goods, or the purchaser and consumer of the goods of some other person.

An individual’s demand is constrained by his ability to produce goods demanded by others. The more goods that an individual can produce, the more goods he can demand.

Expanding Private Savings: Key to Economic Growth

Without the expansion and the enhancement of the production structure, it is difficult to increase the supply of goods and services. The expansion and enhancement of the production structure hinges on the expansion of production, private saving, and capital investment. Saving supports individuals in the various stages of production. It supports individuals that are employed in the enhancement and the expansion of the production structure. Hence, what matters for economic growth is not just tools, machinery, and labor, but saving and investment in capital goods.

Government Is Not a Wealth-Generator

Contrary to popular thinking, the government does not produce any wealth. Increases in government spending cannot grow the economy. By nature, the government must take from the private, productive economy to facilitate any of its actions. By doing this, the government weakens the wealth-generating process and undermines prospects for economic recovery during a downturn. According to Rothbard,

Since genuine demand only comes from the supply of products, and since the government is not productive, it follows that government spending cannot truly increase demand.

Likewise, an increase in money supply only sets in motion an exchange of nothing for something. This means a weakening in the process of wealth formation and leads to economic impoverishment.

An important factor that makes the fiscal and monetary stimulus appear to “work” is if the amount of private savings is large enough to support non-wealth generating activities while still permitting a growth rate in the activities of wealth generators. It also gives the appearance of wealth as new sectors are stimulated. Additionally, if funded by inflation, the benefits of inflation appear early and are only realized later.

If, however, voluntary saving is declining, then, regardless of any increase in government spending and inflation by the central bank, overall economic activity cannot be revived. In this case, the more the government spends, and the more the central bank inflates, the more will be taken from wealth-generators, thereby weakening any prospect for a recovery. Additionally, these measures will further distort the economy.

As one can see, not only does the increase in the expansionary fiscal and monetary policies not raise overall output, but, on the contrary, it leads to a weakening in the process of wealth generation in general. According to Say,

. . .the only real consumers are those who produce on their part, because they alone can buy the produce of others, [while]. . .barren consumers can buy nothing except by the means of value created by producers.

Conclusion

By popular thinking, increases in government spending and central bank inflation strengthens the economy’s overall demand. This, in turn, sets in motion increases in the production of goods and services. What we have here is a claim that “demand creates supply.” However, to be able to exchange something for goods and services, individuals must first have something that others want. This means that, in order to demand goods and services, individuals must produce something useful first. Hence, supply drives demand and not the other way around. Governments, by nature, must take from the private, productive sector in order to fund their activities. Increases in government spending and the money supply growth rate results in the diversion of savings from the wealth-generators to non-wealth-generators, thus undermining the wealth generating process.
