Joan Robinson in her book The Accumulation of Capital〔Joan Robinson, ''The Accumulation of Capital'' (London: Macmillan & Co. Ltd., 1956)〕 published in 1956, propagated a simple growth model, which reflects the working of a pure capitalist economy, also known as the "Joan Robinson's Growth Model". However, the Accumulation of Capital was a terse book and in one of her other books entitled Essays in the theory of Economic Growth,〔Joan Robinson, ''Essays in the Theory of Economic Growth'' (London: Macmillan & Co. Ltd., 1963)〕 she tried to lower the degree of abstraction. The growth model was propagated in verbal terms, where later on the mathematical formalization was put forward by Kenneth K. Kurihara. Assumptions: # There is a laissez-faire closed economy. # The factors of production are capital and labour only. # There is neutral technical progress. # There are only two classes: workers and entrepreneurs among whom the national income is distributed. # Workers save nothing and spend their wage income on consumption. # Entrepreneurs consume nothing, but save and invest their entire income for capital formation. # There is no change in the price level. # Saving is a function of profit. ==The Model== The entrepreneurs total profit and the workers total wage bill constitute the Net National Income in Joan Robinson's Growth Model. It can be mathematically expressed as pY=wN+πpK where Y is the net national income, w is the money wage rate, N the number of workers employed, K is the amount of capital utilized, p is the average price of output as well as of capital and π is the gross profit rate (including the rate). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Joan Robinson's growth model」の詳細全文を読む スポンサード リンク
