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 »

Reserves

The deposits and currency created by the Federal Reserve are the reserves of the modern system. It would seem that if the Fed could control the amount of these reserves, it could thereby limit the ability of banks to lend, and thus control their ability to create deposits. By controlling reserves, the Fed could control the total quantity of money. As we saw earlier, real reserves did constrain banks. It has seemed plausible, and monetarists everywhere have believed, that modern, nominal reserves could provide a similar constraint. But central banks all around the world, including the Federal Reserve, have tried to exercise such control, most recently in the late 1970s and early 1980s, and, in virtually every case, their attempts have failed.

Suppose, for example, that the GDP growth rate exceeds the interest rate by five percentage points. Then the steady-state deficit-to-GDP ratio will be 5 per cent of the debt-to-GDP ratio. If the debt-to-GDP ratio is at, for example, 60 per cent, then the primary deficit-to-GDP ratio can be permanently maintained at 3 per cent. Incidentally, these figures are the same as those stipulated in the European Union Maastricht Treaty as ‘convergence criteria’ for debt and deficit. Note that if the GDP growth rate exceeds the interest rate by five percentage points, then no less than one-fifth of the public sector in our ’small government‘ example, and one-tenth of the ‘big government‘ example, can be permanently financed by allowing the government debt to grow continuously. Taxpayers would be relieved accordingly. Read the rest of this entry »
