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 »

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.

The government budget tends to move counter-cyclically. In a slump, incomes will be reduced and spending curtailed, so tax collections will fall, but welfare and related spending to support the unemployed will tend to rise. Other government budget items are likely to be unaffected. Hence, the overall effect will be to throw the budget into deficit. By contrast, in a boom, tax collections will rise and welfare spending will tend to decline, so a surplus will tend to emerge. In short, in an economy with demand-based cyclical fluctuations, the central government budget will tend to move in a counter-cyclical fashion.

Now consider the monetary implications of deficits and surpluses. A deficit arises when the government spends more than it receives in taxes; this means a net increase in money in the system. Such money will appear as excess reserves in the banking system. If allowed to remain, it will drive down interest rates. Looked at another way, it will drive up security prices. A surplus is just the opposite; it arises when the government spends less than it takes in, and it creates a reserve deficiency, tending to force interest rates up. Read the rest of this entry »

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 »

William Vickrey (1996: 10) argued, ‘The “deficit” is not an economic sin but an economic necessity. Its most important function is to be the means whereby purchasing power not spent on consumption, nor recycled into income by the private creation of net capital, is recycled into purchasing power by government borrowing and spending. Purchasing power not so recycled becomes non-purchase, non-sales, non-production and unemployment.’ In an endogenous money world, there can be no crowding out unless the monetary authority stops lending.

The recent Asian financial troubles and IMF intervention have once again given credence to the view that increasing levels of debt will eventually lead to lenders refusing to take up further public borrowing. Usually this is cast in terms of countries with low levels of capital that have major private debt denominated in a foreign currency used to finance imports. Crises occur when the export revenue, which services the debt, falls for one reason or another. But none of these countries would have any trouble issuing debt in its own currency.

The International Labour Office (1999) argues:

[A]ny strategy for full employment must be based on a sound macroeconomic framework. To achieve this, unsustainable current account imbalances, or foreign debt accumulation, must be reduced and low rates of inflation achieved. This requires the continuous adjustment of policies, a realistic exchange rate, fiscal discipline and wage moderation (wage increases in line with labor productivity). But in times of global deflation this is not necessarily sufficient as a guide to policy, and a boost to demand may be needed, perhaps going so far as to generate expectations of inflation, in addition to the accepted policy of balancing budgets over the business cycle as a whole (International Labour Office, 1999).
