Cumulative process

Cumulative process is a contribution to the economic theory of interest, proposed in Knut Wicksell's 1898 work, Interest and Prices. Wicksell made a key distinction between the natural rate of interest and the money rate of interest. The money rate of interest, to Wicksell, is the interest rate seen in the capital market; the natural rate of interest is the interest rate at which supply and demand in the market for goods are in equilibrium – as though there were no need for capital markets.There is a certain rate of interest on loans which is neutral in respect to commodity prices, and tends neither to raise nor to lower them. This is necessarily the same as the rate of interest which would be determined by supply and demand if no use were made of money and all lending were effected in the form of real capital goods. It comes to much the same thing to describe it as the current value of the natural rate of interest on capital.' Cumulative process is a contribution to the economic theory of interest, proposed in Knut Wicksell's 1898 work, Interest and Prices. Wicksell made a key distinction between the natural rate of interest and the money rate of interest. The money rate of interest, to Wicksell, is the interest rate seen in the capital market; the natural rate of interest is the interest rate at which supply and demand in the market for goods are in equilibrium – as though there were no need for capital markets. According to the idea of cumulative process, if the natural rate of interest was not equal to the market rate, demand for investment and quantity of savings would not be equal. If the market rate is beneath the natural rate, an economic expansion occurs and prices rise. The resulting inflation depresses the real interest rate and causes further expansion and further price increases. The theory of the cumulative process of inflation is an early decisive swing at the idea of money as a 'veil'. Wicksell's process was much in line with the ideas of Henry Thornton's earlier work. Wicksell's theory claims, that increases in the supply of money lead to rises in price levels, but the original increase is endogenous, created by the conditions of the financial and real sectors.
