Shaikh’s wrong theory of interest rates
“The interest rate is the price of finance,” Shaikh writes at the beginning of Chapter 10, “Competition, Finance, and Interest Rates.” Shaikh treats the rate of interest as fluctuating around the price of production of the “provision of finance.” Late in Chapter 10, Shaikh indicates he was confused on this subject in the 1970s and the early 1980s but brought to his current views by the Sraffrian-neo-Ricardian Italian economist Carlo Panico. Is this the correct approach to ascertaining what actually determines the rate(s) of interest? I believe it is not.
Do interest rates really fluctuate around a “price” of the provision of finance the way market prices fluctuate around prices of production? Strictly speaking, price is the value of one commodity measured in terms of the use value of the commodity that serves as the universal equivalent—money. According to this definition, interest rates are not prices at all.
It is true that we often use price in a looser sense. For example, we talk about the prices of securities that are in reality legal documents that entitle their owners to flows of income. Another example is the price of unimproved land whose owners hold titles to flows of ground rent. It would be absurd to talk about the price of production of unimproved land if only because unimproved land is a form of wealth produced by nature and not by human labor.
Some other ‘non-price’ prices
Another example of a price that is not a real price is the dollar “price” of gold. This very important economic variable is not really a price at all but instead measures the amount of gold that a dollar represents at any moment. Other examples of “non-price” prices are the “price” of one currency in terms of another—exchange rates—and the price of politicians.
