Circular cumulative causation is a theory developed by Swedish economist Gunnar Myrdal in the year 1956. It is a multi-causal approach where the core variables and their linkages are delineated. The idea behind it is that a change in one form of an institution will lead to successive changes in other institutions. These changes are circular in that they continue in a cycle, many times in a negative way, in which there is no end, and cumulative in that they persist in each round. The change does not occur all at once as that would lead to chaos, rather the changes occur gradually. Gunnar Myrdal developed the concept from Knut Wicksell and developed it with Nicholas Kaldor when they worked together at the United Nations Economic Commission for Europe. Myrdal concentrated on the social provisioning aspect of development, while Kaldor concentrated on demand-supply relationships to the manufacturing sector. == Dynamics == In the characteristics that are relevant to the development process of an economy Myrdal mentioned the availability of natural resources, the historical traditions of production activity, national cohesion, religions and ideologies, economic,social and political leadership. Myrdal stated that the immediate effect of closing down certain lines of production in a community is the reduction of employment, income and demand. Through the analysis of the multiplier he pointed out that other sectors of the economy are also affected. Then he argued that the contraction of the markets in that area tends to have a depressing effect on new investments, which in turn causes a further reduction of income and demand and, if nothing happens to modify the trend, there is a net movement of enterprises and workers towards other areas. Among the further results of these events, fewer local taxes are collected in a time when more social services is required and a vicious downward cumulative cycle is started and a trend towards a lower level of development will be further reinforced. A status of non-equilibrium is shaped, or as he writes: About Economic Theory and Underdeveloped Regions Myrdal wrote that ‘the argument moves on a general and methodological plane in the sense that the theory is discussed as a complex of broad structures of thought’ (His aim was to submit ‘broad generalisations, as a ‘theory’ is permitted to be, (in order to) grasp the social facts as they organize themselves into a pattern when viewed under a bird’s-eye perspective Into this general vision, the specific characteristic. source:(Myrdal, G. 1957, Economic Theory and Underdeveloped Regions, London: University Paperbacks, Methuen)) Myrdal developed further the circular cumulative causation concept and stated that it makes different assumptions from that of stable equilibrium on what can be considered the most important forces guiding the evolution of social processes. These forces characterise the dynamics of these processes in two diverse ways. Yet, the provision of data or other information regarding single economies was beyond the scope of his work.He claimed that in the normal case there is no such a tendency towards automatic self-stabilisation in the social system.The system is by itself not moving towards any sort of balance between forces,but is constantly on the move away from such a situation Myrdal used the expressions ‘approach’, ‘theory’ and ‘general theory’ as synonyms. In his subsequent writings, however, he mainly referred to ‘approach’, defining it as something containing, among other things, theories. He wrote that by this term he meant a collection of devices,like ‘the concepts, models,and theories we use, and the way in which we select and arrange observations and present the results of our research’. In the preface to his Economic Theory and Underdeveloped Regions Myrdal wrote that Myrdal called for economists to proceed by confronting the ‘facts of life’ with theories.The relation between theory and facts is however not simple. 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「Circular cumulative causation」の詳細全文を読む スポンサード リンク
