joan robinson model of capital accumulation
The Golden age depends upon growth ratio. Therefore = ∆K /K =π or ∆ K /K = πK/K but from equation (iii) above, we know. Welcome to EconomicsDiscussion.net! 7. However, if an increase in labour supply is not accompanied by proportionate increase in the capital supply, then it will cause unemployment in the economy. If this is done the task of generalization of the General Theory may become complete. Labour and capital are the only productive factors. In other words, the rate of growth of surplus which is HC must be able to absorb the rate of growth of labour force which is ON here. Therefore, in a Restrained Golden age, proportion of unemployment is rising due to insufficient rate of accumulation, standard of workers falls unless real wage for employed workers is not rising sufficiently or opportunities for self employment are not sufficiently favoured. In this classic work Joan Robinson goes back to the beginning and works out the basic theory that is needed for a coherent treatment of the problems that present themselves in a developing economy. Mrs. Robinson’s golden age is an era of plenty and not one of stagnation. Thus, she is interested in explaining the fundamental nature of economic growth according to the ‘capitalist rules of the game’? Therefore, the Bastard Golden Age implies that stock of capital equipment does not grow faster because of inflation barrier. If, however, ∆N/N > ∆K/K there will be unemployment in the economy and vice-versa. According to the model, there is no technical progress. The continuous decline in the level of employment is an indicator of severity of limp which, in turn, may lead to the problem of inflation and unemployment. This situation is impossible. A tangent is drawn touching at C. Now the rate of growth of capital = ∆I/I =Output- Input/ Input = Surplus/Input = HC/OW x OK =HC/WH x 1/OW (because tan β = tan β), therefore, HC /OK =HC/WH OK = WH = ON and OW = HC . there is no progress in technology. Howevcr, the appendix makes no attempt ... part in our present unclassical model of the classical proposition that capital accumulation leads idtimutely to the stationary state. Thus, any relaxation of credit would encourage to increase the stock and employment of more and more workers which means the invitation to inflation which is quite uncontrollable. Kahn, originally used the term ‘Bastard Golden Age’. The equilibrium is likely to be restored through technological improvement and the shifting of the whole production function so that the economy gets itself adjusted to a higher capital labour ratio. Her blend of theory and realism is what we all strive for in parsing modern economic problems. 9. In other words, lower rate of profit always affects the supply of capital adversely which in turn widens the gap between supply of capital and labour. Hence, a situation in which the rate of capital accumulation is low due to the threat of rising money wages an account of rise in prices, may be called as Bastard Golden Age. Joan Robinson Model Of Capital Accumulation. A constant capital-output ratio is visualised in ‘Golden Age’ and if this is so, it follows that shares of wages and profits will remain constant. Total wage bill is the product of real wage rate and number of workers. This age begins with full employment situation where the rates of accumulation and profit are very high and techniques of low capital intensity are being installed. The model is based on the closed economy but this is unreal because underdeveloped countries are open rather than closed economies in which foreign trade and aid play creditable role in increasing the growth rate. the growth rate of the economy is determined by the saving income ratios and the productivity of capital. (f) There is a laissez-faire closed economy. Total profit is the product of profit rate and amount of capital invested. The investment has to be increased continuously which tends to raise the demand for factors but their supply cannot be increased to meet the demand. 11. Let us convert it into forms consistent with Robinson’s assumptions, thus: In this figure horizontal axis measures capital-labour ratio (K/N) in quadrant I. Vertical axis measures the labour income ratio or labour productivity (Y/N). Economic analysis, which began as an inquiry into the Nature and Causes of the Wealth of Nations, got lost for nearly a hundred years in an excessive preoccupation with relative prices and outputs in a static world.
