The endogenous determination of the interest rate

In a boom, banks will lend more and will seek to create new deposits or issue additional notes. To support these activities, they will have to attract additional reserves. This will lead them to bid up interest rates, as they seek to attract idle reserves from one another and from hoards. In a slump, they will issue less and lend less, and will seek to shed reserves, lowering interest rates. In other words, while long-term average rates are determined by costs and competition, current interest rates reflect the balance of supply and demand in the market. They move pro-cyclically.

This is illustrated by a simple model. On the one hand, the rate of interest (in relation to the rate of profit), is likely to affect investment inversely, and investment, in turn, will have an impact on prices and employment. Changes in prices and employment will call for changes in reserves. Read the rest of this entry »

In its earliest and simplest forms, the gold standard meant that the money in circulation, including the money the government minted, consisted of gold coins. When the US officially joined the gold standard in 1879, the value of the dollar was set as equal to the value of 23.22 fine grains of gold, where 480 fine grains made a fine troy ounce. This was equivalent to $20.67 per ounce.

Under the gold standard, the constraint on the creation of bank money posed by reserves is critical. Bank money consists of notes issued as claims to real money, that is, to gold or silver coins, money with intrinsic value. But at any time, most of the public would prefer to use the more convenient paper money, provided they are confident that they can convert the (intrinsically worthless) paper to gold at a moment’s notice. For this purpose, reserves are kept in proportion to the note issue. Read the rest of this entry »

A ‘transformational growth’ perspective (Nell, 1998a) would suggest that these principles are connected in an evolutionary pattern: as technology developed, production and employment took on new forms, and came to require different kinds of financing (Nell, 1998b). To keep pace, the monetary system also had to adapt and develop in new ways.

This took place in several stages. In the first instance, as transactions became more complex, metallic money proved inconvenient. Paper claims to gold could be used more easily, and came to replace gold. But bankers noticed very early that a given supply of gold could support a larger amount of circulating paper, since only a fraction would be presented for conversion at any given time. Convertible paper based on a fractional reserve, however, is fiduciary money. It is based on the trust the public has in the banks. Read the rest of this entry »
