Eliminating the Dual Function of Money

In the previous post, we explored the dual function of money and why financial and economic stability can only truly be attained by using commodities themselves, instead of money, as the store of economic value. Once commodity-based valuation is agreed, the question arises: Since commodities have different values, how can a universal valuation be attained for use in trade? Adam Smith asked the same question over 200 years ago and came up with an answer:

Labour.. is the only universal and the only accurate measure of value, or the only standard by which we can compare the values of different commodities at all times and at all places. We cannot estimate.. the real value of different commodities from century to century by the quantities of silver which were given for them. We cannot estimate it from year to year by the quantities of corn. By the quantities of labour we can, with the greatest accuracy, estimate it both from century to century and from year to year. From century to century, corn is a better measure than silver, because, from century to century, equal quantities of corn will command the same quantity of labour more nearly than equal quantities of silver. From year to year, on the contrary, silver is a better measure than corn, because equal quantities of it will more nearly command the same quantity of labour.

Wealth of Nations

In other words, the benchmark commodity depends on the length of time of the transaction. The values involved in a very short term trade such as purchasing bread for the day's consumption can be based on money, which in turn is based on a gold standard. The values in a very long term trade such as the non-speculative purchase of land, however, should be based on a more stable commodity such as wheat. This prevents the price inflation of land which affects all other commodities.

Is wheat really stable?


Adam Smith advocated wheat as the universal measure of long-term value because of its stability. The chart below shows that long term prices of grain are more stable than those of oil or gold. Of the major commodities, oil has the highest price extremes while gold has the most volatile prices:


Adam Smith explained that the relative stability of grains over oil and metals is due to the fact that grains can be grown and known by more people than other commodities. The drilling of oil and the prospecting for gold, in contrast, can only be known and done by people who have the required capital and expertise.

..it may sometimes be of use to compare the different real values of a particular commodity at different times and places... We must in this case compare, not so much the different quantities of silver for which it was commonly sold, as the different quantities of labour which those different quantities of silver could have purchased. But the current prices of labour at distant times and places can scarce ever be known with any degree of exactness. Those of corn, though they have in few places been regularly recorded, are in general better known.. We must generally, therefore, content ourselves with them..

The stability of long term wheat prices is the major reason why Smith advocated land (or at least land rent) to be valued in wheat. Since all economies rely on land, the stability or fairness in the valuation of land will, in turn, lead to more stability in all other commodities, helping to prevent the severity of bubbles and crashes.
