Not a sustainable growth
By Dr Aqdas Ali Kazmi
ECONOMIC growth is a complex phenomenon. How much growth is achieved by a country for how long, using which strategies, emerging from which sectors and is shared by whom are all inter-related questions. A review of literature on economic growth along with growth experiences across the globe suggest that the growth performance of a country can be analysed using 10 criteria of assessment: sustainability, balance, optimality, equity, self-sufficiency, diversification, externality, efficiency, stability and structuralism.
Taking the first criterion of sustainability, economic growth experienced by different countries can be classified into two categories — the sustainable and the unsustainable. The former is self-sustaining, environment-friendly and is based on the normal use of the natural and mineral resources of a country. Unsustainable growth, on the other hand, is not only erratic, it is environmentally degrading and is associated with the abnormal exploitation of natural wealth.
Economic growth in Pakistan does not meet the sustainability criteria as it is accompanied by unsustainable pressures of population and urbanisation, rapid deforestation and depreciation of physical infrastructure as well as uncontrolled pollution.
The criterion of balance helps in identifying whether economic growth experienced by a country is balanced or unbalanced. Economic growth is considered to be balanced when various regions comprising a country, its rural-urban and its male-female populations or its major sectors such as agriculture and industry are evenly and fairly developed. Unbalanced growth has the opposite characteristics reflected in wide disparities in the levels of economic development. This criterion establishes that the economy of Pakistan continuous to suffer from dualism as certain regions, sub-sectors and segments of population remain grossly under-developed while others show the opposite picture.
Coming to optimality, the private and public sectors in an economy must play their optimal roles to generate synergies of partnership and to ensure maximum level of employment and output. In the modern world, rigid adherence either to the Platonic-cum-Marxian type centralised state or the Aristotelian-cum-Smithsonian type laissez-faire economy has waned. At the same time, there is a general acceptance of economic planning as an essential tool of national development.
State intervention is at present considered to be a sine qua non for correcting a host of market failures. Given the resurgence of the philosophy of economic neo-liberalism, the fact remains that even in the most liberalised economies of the world, economic planning continues to determine numerous variables of the economy such as savings, investment, money supply, prices, exports, imports, exchange rate and GDP growth.
In the case of Pakistan, both the public and the private sectors have played a sub-optimal role in economic development and have failed to realise its full potential. Whereas the public sector has been constrained by insufficient resources, inefficiencies, wastage and corruption, the private sector has suffered from inertia. At the same time, a lack of vision and foresight has afflicted both sectors for many decades, with serious consequences for the process of economic growth.
The criterion of equity, the fourth in our analysis, focuses on the distributional and welfare aspects of growth. If economic growth leads to greater inequity in income and wealth distribution and a large portion of the population finds itself further down in the scale of living standards, such growth would be classified as anti-poor. An increase in the people’s level of sustenance is the primary goal of economic growth. For that reason, there has been widespread disillusionment with the “trickle-down” theory which stipulates that the benefits of economic growth will automatically filter down to the poorest of society.
Even the “trickle-down” effect of economic growth is neutralised if the taxation system in place is regressive. Furthermore, if economic growth synchronises with a lax monetary policy and high inflationary pressures, the poor sections of society would suffer the most. Hence the analysis of economic growth needs a holistic approach which takes into account the impact of fiscal, monetary and trade policies for assessing the overall implications of economic growth.
For evaluating the growth of a country, the fifth criterion i.e self-sufficiency is extremely relevant. Self-sufficiency in the present context refers to the level of domestic resource mobilisation to finance gross investment in the country. This is the main determinant of economic growth. If a country continues to finance its private and public investment from domestic and foreign loans, the resultant growth could be identified as the “borrowed growth”.
A large number of developing countries have been heavily dependent on external aid and are now badly caught in the debt trap. These countries need to borrow more to service their earlier debts. At the same time, external borrowing brings into the country borrowed technologies and borrowed strategies. As a consequence, the country often loses its autonomy in policymaking. The sixth criterion for assessing the growth process of a country is labelled as the criterion of diversification. In a large number of developing countries in Asia and Africa, growth is critically dependent upon the production of one or two raw products such as rubber, cotton, jute, cocoa, coffee, tea etc. In these cases, deterioration of barter and income terms of trade is universal and these countries fail to mobilise sufficient resources for long-term development.
Despite registering a growth rate of about five per cent per annum on an average basis during the last 58 years, Pakistan’s economy is not sufficiently diversified and the dictum that the cotton output has cradled Pakistan’s GDP growth, as one World Bank economist put it, holds good even today. Without diversification, Pakistan’s economy will be confronted with serious challenges of globalisation which have emerged with the signing of the Uruguay Round Agreements and that are being implemented by the World Trade Organisation.
The seventh criterion for analysing the structure of economic growth is externality. Here, the possible impact of economic growth on the external sector of the country concerned is diagnosed. This includes the sub-components of balance of payments such as exports, imports, invisibles, etc. If growth in real GDP leads to widening of the trade deficit or the current account deficit, it puts pressure on the foreign exchange reserves of the country.
In this case, assets may be created through the process of economic growth but, at the same time, the creation of external sector liabilities due to, say, excessive imports could drastically reduce the benefits of economic growth. Pakistan’s estimated trade deficit of $11 billion and the current account deficit of around $5 billion for the year 2005-06 only underline the adverse externalities of an otherwise high growth rate of 6.6 per cent achieved for the year.
The eighth criterion of growth assessment is that of efficiency. According to this criterion, different countries achieve different levels of output with the same level of factor inputs. The efficiency factor is commonly measured by the parameters of the Incremental Capital Output Ratio (ICOR) which indicates the additional investment required to generate one unit of output and labour-output ratio i.e. additional labour needed to create one unit of output.
A lower value of these parameters indicates the relative efficiency of factor use. The main determinants of efficiency are capacity utilisation, skills and training of the work force, management techniques and the nature of technology. Even though all these factors are important for enhancing efficiency of factors of production, the role of technology in augmenting the factor productivity is now considered as the most critical. Dani Rodrik, professor of international political economy at John F. Kennedy School of Government at Harvard University, in his recent research covering 140 countries has measured the relative shares of capital, labour and total factor productivity or TFP which is an indicator of the technology factor. According to his work, in industrial countries, a major contribution to economic growth comes from TFP rather than factor accumulation. In countries like Germany, UK, France, Japan, Brazil, the contribution of TFP has varied from 25 per cent to 50 per cent. In the case of Pakistan, the share of TFP has been almost negligible which suggests that Pakistan’s growth performance has not synchronised with any technological advancement.
If economic growth is volatile and excessively fluctuating, it renders policymaking extremely difficult. Therefore, the criteria of stability the ninth in our analysis, can be applied to assess the inherent variability of economic growth and its potential effects at the micro- and macro-economic levels. Another aspect of stability is the relative fluctuations occurring in the price and exchange rate levels. If high growth rates occur along with high inflation rates or large depreciation of the domestic currency, growth benefits could be neutralised.
The last criterion for evaluating the quality of economic growth can be identified as that of structuralism. The dynamics of economic growth require that the structure of economies should be changing with lower shares for agriculture and rising shares for the industrial as well as the services sectors. It is vital that economic growth should be followed by structural transformation. Without such a transformation, the economy remains weak and vulnerable to external shocks.
When evaluated against these criteria, Pakistan’s economic growth experience does not appear to be highly favourable. Despite a reasonable growth rate achieved over the last five and a half decades, the country continues to suffer from gaps in poverty, human development, trade, saving-investment and technology. It appears that it will take some time for Pakistan to reach the take-off stage.
