1 Historical growth modelling
Rostowâs âtake-offâ and Rosenstein-Rodanâs âbig pushâ

1.1 Introduction
Of the development economists of the 1950s and 1960s Walter Rostow (1916â2003) stands out as one who built an historical-based model in order to identify the stages of development of economic systems and, in particular, to identify the main factors which can explain the transformation of an undeveloped country to a developed country. In Rostowâs âstages of economic growthâ model there are five evolutionary stages of possible economic development, as based on his study of the historical patterns of development of the advanced nations up to 1960. The critical stage, and indeed, the most contentious, in Rostowâs model, is the âtake-offâ stage, which characterizes the period when an economy experiences a transformation decisive in putting it on the path to sustained growth and development and becoming an economically advanced nation. This âtake-offâ notion has subsequently been employed by some economic historians and development economists. In connection to this model Rostow endeavoured to develop a theoretical apparatus â âa systemâ â for interpreting economic history and identifying the main forces in society which explained the take-off of economies. This attempt by Rostow to bring together theory and history to explain economic growth is itself of great interest.
Another to develop a model in post-war development economics was Paul Rosenstein-Rodan (1902â1985) with his âbig pushâ model. Different from the historical-based model of Rostow, this model was instead developed by Rosenstein-Rodan from theoretical principles to rationalize a policy of large-scale co-ordinated investment that would provide the momentum â a âbig pushâ â to the development of undeveloped regions.
There is an affinity between these two models in the sense that Rosenstein-Rodanâs big push can be seen as an economic strategy to achieve Rostowâs take-off. Indeed, consistent with Rosenstein-Rodanâs model, Rostow argued that the crucial take-off stage of economic development involved a marked acceleration in the growth of investment which embodied rapid technical progress.1
This chapter will critically examine the models of these two development economists and appraise their contemporary significance to explaining growth and proposing policies which promote economic development. In section 1.2 we examine Rostowâs historically-based âstages of economic growthâ model. Then, in section 1.3, we examine the theoretical apparatus developed by Rostow, principally to explain the take-off growth stage. In section 1.4 we consider Rosenstein-Rodanâs âbig pushâ model and his grand policy to promote economic development. Our conclusion in section 1.5 critically appraises these two models, showing that their insights can be better appreciated by reference to a coherent theoretical framework provided by the demand-led approach to explaining growth.
1.2 Rostowâs âstages of economic growthâ model
The âstages of economic growthâ model began with the notion of the âtake-offâ first articulated by Rostow in The Process of Economic Growth, published in 1952: âThe process of take-off may be defined as an increase in the volume and productivity of investment in a society, such that a sustained increase in per capita real income resultsâ.2
This notion was considerably elaborated by Rostow in terms of the history of economic development in the article, âThe Take-off into Sustained Growthâ, published in the Economic Journal in 1956. In this article Rostow formulated a three-stages model of the growth process, consisting of âpreconditions for take-offâ, âthe take-offâ, and âwhen growth becomes normal and relatively automaticâ.3 It was in the article âThe Stages of Economic Growthâ, published in The Economic History Review in 1959, that Rostow first articulated his âstages of economic growthâ model, consisting of five historical stages of development.4 The most comprehensive account of the model was then subsequently given in his book, The Stages of Economic Growth: A non-Communist Manifesto, first published in 1960.5 This book included a global geo-political outlook, a repudiation of Marx and Marxism and a rationalization of the emergence of communism in the twentieth century with reference to the Cold War. In this connection Rostow was quite explicit that a major motive for promoting global economic development was to staunch the spread of communism. Indeed, Rostow proposed his model â understood in conjunction with his theoretical apparatus â as a superior alternative to that which he attributed to Marx and the âMarxistsâ.6 But, as indicated above, Rostowâs model was fundamentally developed out of a desire to explain the growth process from an historical perspective. Hence, in the opening sentence of his book Rostow writes: âThis book presents an economic historianâs way of generalizing the sweep of modern history. The form of this generalization is a set of stages-of-growthâ.7
The five stages of Rostowâs model consists of (1) âthe traditional societyâ, (2) âpreconditions for take-offâ, (3) âthe take-offâ, (4) âthe drive to maturityâ and (5) âthe age of high mass consumptionâ. According to Rostow each country can be categorized as being in one of these stages of economic development and in which only the most advanced countries have historically evolved through all five stages. Hence, the advanced nations, led by the United States and including Britain, France, Germany and Japan, are considered to have reached the fifth stage of growth; whereas, for example, Turkey, Argentina, China and India, were judged to be only in the take-off stage.8 On the basis of this model Rostow estimated timelines for when countries in his study evolved through each of the historical stages of development from the take-off stage onwards. Thus, for example, Rostow estimated that for Britain, the first nation to take-off, the take-off occurred in the period 1783â1802, the drive to maturity occurred in the period 1803â1850 and the economy entered the stage of mass consumption from the early 1930s.9 Each of the five evolutionary stages in Rostowâs model are defined by certain economic, social and political characteristics considered important to comprehending the general pattern of development in modern history.
1.2.1 Traditional society
The most economically backward stage, âthe traditional societyâ, is defined by Rostow as âone in whose structure is developed within limited production functions, based on pre-Newtonian science and technology, and on pre-Newtonian attitudes towards the physical worldâ where âNewton is here used as a symbol for that watershed in history when men came widely to believe that the external world was subject to few knowable laws, and was systematically capable of productive manipulationâ.10 This stage is characterized by technological backwardness with an incapacity for systematic technological progress thereby placing a limit âon the level of attainable output per headâ.11 For Rostow the economy is overwhelmingly based on agriculture. It is a society characterized by a âhierarchical social structureâ in which there is limited social and economic mobility and in which âfamily and clan connexions played a large role in social organizationâ.12
Whilst Rostow does not use the term feudalism to describe this historical stage he writes that it is often characterized by âcentral political ruleâ but in which the âcentre of gravity of political power generally lay in the regions, in the hands of those who owned or controlled the landâ.13 In the contemporary âpost-Newtonianâ world the traditional society is one in which there is the possibility for technological progress but it remains âuntouched or unmoved by manâs new capability for regularly manipulating his environment to his economic advantagesâ.14 Nevertheless, the meaning of âthe traditional societyâ in Rostowâs model is obscure, essentially capturing all those economically backward societies which have yet to evolve into the next historical stage of establishing the preconditions for take-off.
1.2.2 The pre-conditions for take-off
The second stage of growth in Rostowâs model is one in the process of transition from tradition society to the take-off stage in which the preconditions for take-off are developed. It is a period characterized by society exploiting âthe fruits of modern science, to fend off diminishing returnsâ and in which âthe insights of modern scienceâ are âtranslated into new production functions in both agriculture and industryâ.15 The historical reference for this âpreconditions of take-offâ stage appear to be âWestern Europe of the late seventeenth and early eighteenth centuriesâ which he associates with modernity and th...
