The Wealth of Nations_ Books 4-5 - Adam Smith [74]
The ingenious and well-informed author of the tracts upon the corn trade has shown very clearly that, since the bounty upon the exportation of corn was first established, the price of the corn exported, valued moderately enough, has exceeded that of the corn imported, valued very high, by a much greater sum than the amount of the whole bounties which have been paid during that period. This, he imagines, upon the true principles of the mercantile system, is a clear proof that this forced corn trade is beneficial to the nation; the value of the exportation exceeding that of the importation by a much greater sum than the whole extraordinary expense which the public has been at in order to get it exported. He does not consider that this extraordinary expense, or the bounty, is the smallest part of the expense which the exportation of corn really costs the society.
The capital which the farmer employed in raising it must likewise be taken into the account. Unless the price of the corn when sold in the foreign markets replaces, not only the bounty, but this capital, together with the ordinary profits of stock, the society is a loser by the difference, or the national stock is so much diminished. But the very reason for which it has been thought necessary to grant a bounty is the supposed insufficiency of the price to do this.
The average price of corn, it has been said, has fallen considerably since the establishment of the bounty. That the average price of corn began to fall somewhat towards the end of the last century, and has continued to do so during the course of the sixty-four first years of the present, I have already endeavoured to show. But this event, supposing it to be as real as I believe it to be, must have happened in spite of the bounty, and cannot possibly have happened in consequence of it. It has happened in France, as well as in England, though in France there was not only no bounty, but, till 1764, the exportation of corn was subjected to a general prohibition. This gradual fall in the average price of grain, it is probable, therefore, is ultimately owing neither to the one regulation nor to the other, but to that gradual and insensible rise in the real value of silver, which, in the first book of this discourse, I have endeavoured to show has taken place in the general market of Europe during the course of the present century. It seems to be altogether impossible that the bounty could ever contribute to lower the price of grain.
In years of plenty, it has already been observed, the bounty, by occasioning an extraordinary exportation, necessarily keeps up the price of corn in the home market above what it would naturally fall to. To do so was the avowed purpose of the institution. In years of scarcity, though the bounty is frequently suspended, yet the great exportation which it occasions in years of plenty must frequently hinder more or less the plenty of one year from relieving the scarcity of another. Both in years of plenty and in years of scarcity, therefore, the bounty necessarily tends to raise the money price of corn somewhat higher than it otherwise would be in the home market.
That, in the actual state of tillage, the bounty must necessarily have this tendency will not, I apprehend, be disputed by any reasonable person. But it has been thought by many people that it tends to encourage tillage, and that in two different ways; first, by opening a more extensive foreign market to the corn of the farmer, it tends, they imagine, to increase the demand for, and consequently
