Wealth may be transferred from country to country in the form of goods and services, but
by far the greatest transfers are made in the form of money. Just as a stable monetary
unit facilitates economic activity within a country, so international economic activity is
facilitated when there are stable relationships between one country’s currency and
another’s. It is not simply a question of the ease or difficulty of translating dollars in yen,
francs or yuans. It is a far more important question of knowing whether an investment
made in the United States, Japan, China or France today will be repaid a decade or more from now in money of the same value – whether measured in purchasing power or in the
currency originally invested.
Various attempts at stabilizing international currencies against one another have followed
the disappearance of the gold standard. Some nations have made their currencies
equivalent to a fixed number of dollars, for example. Various European nations have
created their own international currency, the Euro and the yen has been another stable
currency widely accepted in international financial transactions.
With the spread of electronic transfers of money, reactions to any national currency’s
change in reliability can be virtually instantaneous. Any government that is tempted
toward inflation knows that money can flee from their economy literally in a moment.
The discipline this imposes is different from that one imposed by a gold standard, but
whether it is equally effective will only be known when future economic pressures put
the international monetary system to a real test.
Inventory is a substitute for knowledge. Since you don’t always know just how much inventory you are actually going to need and since inventory costs money, a business enterprise must try to limit how much inventory it has on hand. Those businesses, which have the greatest amount of knowledge and come closest to the optimal size of inventory, will have their profit prospects enhanced. Just as prices in general affect the allocation of resources from one place to another at a given time, so returns on investment affect the allocation of resources from one time period to another. A high rate of return provides incentives for people to save and invest more than they would at a lower rate of return. – A higher rate of return encourages people to consume less in the present so that they may consume more in the future. It allocates resources over time. The present value of an asset is in fact nothing more than its anticipated future returns, added up and discounted for the fac...
