  3. Economic Growth & Development • Economic Growth • In strictly economic terms, economic growth occurs when an economy achieves an increase in its national income, measured by GNP, in excess of its rte of population growth. This will lead to an increase in GNP per capita. • For a long time it was assumed that the existence of poverty in many of the world’s poorer economies could be eradicated if these countries managed to sustain economic growth over a period of time. • As a result economic growth was seen as synonymous with economic development. If economies grew they would also experience development.

  4. Economic Growth & Development • Economic Growth • It was assumed that increased availability of goods and services in an economy would lead to a ‘trickle down’ effect with an impact upon all, including the poorer members of society, in terms of jobs and other economic benefits. • In reality, however, although many developing countries have achieved quite high growth rates in recent years, and although economic growth has resulted in benefits for poorer members of society in some countries, in others the level of living of the mass of the population remained unchanged. In some cases this level may even have deteriorated. • A definition of economic development, related to, but distinct from economic growth, is now accepted

  6. Economic Growth & Development Economic Growth Using measures of economic performance in terms of the value of income, expenditure & output GDP – Gross Domestic Product The value of output produced within a country during a time period GNP – Gross National Product The value of output produced within a country plus net property income from abroad GDP/GNP per head/per capita Takes account of the size of the population Real GDP/GNP Accounts for differences in price levels in different countries

  7. Economic Growth & Development Economic Growth - High economic growth fuelled through capital spending can hide a number of underlying economic problems – how is the income and wealth distributed?

  8. National Income – Problems with using GDP/GNP Reliability of data? How accurate is the data that is collected? Distribution of income? How is the income distributed – does a small proportion of the population earn a high percentage of the income or is income more evenly spread?

  9. National Income – Problems with using GDP/GNP Quality of life? Can changes in economic growth measure changes in the quality of life? Does additional earnings power bring with it additional stress, increases in working hours, increased health and family problems? Impact of exchange rate? Difference in exchange rates can distort the comparisons – need to express in one currency, but which one and at what value?

  10. National Income – Problems with using GDP/GNP Black/informal economy? Some economic activity not recorded – subsistence farming and barter activity, for example Some economic activity is carried out illegally – building work ‘cash in hand’, drug dealing, etc. Work of the non-paid may not be considered but may contribute to welfare – charity work, housework, etc. It might not be pleasant, but what he finds among the refuse could be all he has.

  11. Economic Growth & Development • Economic Development • Economic growth is important but higher income in itself is not sufficient to ensure that there is a rise in the quality of life for the citizens of a country. • Economic development is a much broader view of development than one confined purely to increases in GNP. It provides a different focus for those responsible for development policy planning, and moves away from measures designed purely to increase and maintain an economic growth target.

  12. Economic Growth & Development • Economic Development • According to Todaro and others the movement to a better life can be analyzed and measured against three core values: • SUSTENANCE: The ability to meet basic needs • SELF-ESTEEM: To be a person • FREEDOM FROM SERVITUDE: To be able to choose

Economic Growth & Development Growth versus Development Economic growth may be one aspect of economic development but is not the same Economic growth: A measure of the value of output of goods and services within a time period Economic Development: A measure of the welfare of humans in a society

  20. Indicators of Comparative Development • Classification according to levels of income • The simplest way in which economies can be classified is according to the value of GNP per capita. • Every economy can be classified as low income, middle income (subdivided into lower and upper middle), or high income. • Low-income and middle-income economies are sometimes known as developing economies. • The thresholds btw the categories are updated each year to account for international rates of inflation. While the thresholds are constant in real terms over time.

  21. Indicators of Comparative Development • Classification according to levels of income • Classifying economies in this way is convenient, but it can also be misleading if it is assumed that all countries classed as ‘developing’ are the same stage of development. • In fact economies grouped together in terms of income may well be at completely different development stages. • Nevertheless, categorising economies according to their levels of income provides a simple and measurable way of grouping economies.

  22. Indicators of Comparative Development • Classification according to indebtedness levels • To classify developing economies according to the degree of their indebtedness. • These categories are: severely (or highly) indebted, moderately indebted and less indebted. • The categorisation depends upon a number of measures of international indebtedness, the most important which is the proportion of GNP which is devoted to servicing the debt. • Such a categrorisation is a reflection of the extent to which international indebtedness is an obstacle to economic development.

  23. Characteristics of Developing Economies • The terms ‘developing economies’ is used to describe a great variety of different countries with many differences. • It is wrong to think of them as a distinct group with same characteristics. • Very often the differences which exist between them are related to he geographical area in which the countries are located. Developing countries located in the same region are usually affected by the same type of problem. • There is no ‘typical developing country’, and policies to foster economic development may need to be country specific. The policies appropriate for one may not e appropriate for all.

  24. Characteristics of Developing Economies • Nevertheless, for some purposes it is necessary to treat developing countries as a group and it is useful to indentify their shared characteristics. • Very often the characteristics that they share generate the similar problems that they have to face. • Recognising the differences between developing countries while identifying the characteristics that they have in common can be charaterised as ‘UNITY IN DIVERSITY’

  25. Characteristics of Developing Economies • ‘UNITY IN DIVERSITY’ • Economic Structure • Population Growth and Population Strucuture • Income Distribution • Employment • External Trade • Urbanisation • Technology

  26. Characteristics of Developing Economies • Economic Structure • Economic activity can be placed in three sectors: • The Primary Sector - agriculture and extractive industries, such as coal mining and oil extraction • The Secondary Sector – all manufacturing industries and the construction sector • The Tertiary Sector – service sector • Developing countries typically have a high dependency upon the primary sector. • In those low-income economies, agriculture contributed 30%-60% of output in 1990s • High dependency on agricultural output makes developing countries vulnerable to forces of nature. • In high-income economies the average figure for agricultural production was only 5% or less of GDP.

  27. Characteristics of Developing Economies • Population Growth and Population Structure • More than 95% of world population growth is taking place in developing countries • The theories of Malthus can be applied to the current population problems of developing countries • The essence of Reverend Thomas Malthus’s view as that a country’s population had a tendency to grow in geometric progression over time. • However, food supplies had a tendency to increase only in arithmetic progression because the quantity of land was in relatively fixed supply, and as increasing quantities of ever-more readily available labour were added in production, diminishing returns would set in.

  28. Characteristics of Developing Economies • Population Growth and Population Structure • The tendency over time therefore was that population increases would outstrip increases in food supplies. This would cause a number of ‘checks’ to population growth so that the population would fall to a level sustainable by the available food supplies. • Population grows in geometric progression 1,2,4,8,16,32,64…. • Food supplies grow in arithmetic progression 1,2,3,4,5,6,7…. • These checks included famines brought on by the overpopulation, diseases and epidemics caused by malnourishment, and wars as countries, increasingly desperate to feed their growing populations, fight over dwindling resources

  29. Characteristics of Developing Economies • Population Growth and Population Structure • Comments on Malthusian view of population growth • The main weakness is that Malthusian view fails to recognise the impact of changes in technology on food production and distribution. These changes mean food supplies have increased to be capable of supporting a much higher level of world population. • Nevertheless, malnourishment and famine remain depressing features of many developing countries. • However, these problems are more likely to be caused by a wider range of factors than overall Malthusian analysis would suggest, such as the uneven world distribution of resources, poor management of agricultural sectors, vulnerability to sudden shocks, such as floods and drought , and an inability to respond to these.

  30. Characteristics of Developing Economies • Population Growth and Population Structure • Comments on Malthusian view of population growth • The crippling impact of international debt in developing countries also creates conditions in which human miseries, including hunger and famines, can flourish. • The fact that developing countries have much higher birth rates than the developed economies does not only lead to greater increases in the total population of developing countries but all the attendant problems which this brings. It also has a impact upon the population structure of these countries.

  31. Characteristics of Developing Economies • Population Growth and Population Structure • Dependency ratio=the proportion of dependent, non-productive members in the total population • These developing countries tend to have a large number of very young people considering the age composition. This creates a high dependency ratio. • A proportionally small working population has to produce enough goods and services to sustain not only themselves but also a large number of young people who are economically dependent upon them. • This will give rise to the conditions of poverty and create pressures to force the young into the workforce and cause child labour problems.

  32. Characteristics of Developing Economies • Population Growth and Population Structure • Developed countries also tend to have problems with the age structure of their populations. However, the problem is different. • The birth rate is so low and below the rate required to replace the present population in developed countries. The result is that the population is actually ageing. • Dependency ratios are high because of the high number of old people who are reliant upon the productive proportion of the population for support and this brings problems too.

  33. Characteristics of Developing Economies • Population Growth and Population Structure • The concept of Optimum population. • The optimum population is said to exist when output per head is the greatest, given existing quantities of the other factors of production and the current state of technical knowledge. • As the population grows it can make better use of the stock of the other factors of production such as land and capital, because increasing returns are enjoyed as the population grows. • If as the population increases the output per head continues to grow we could consider the country to be underpopulated.

  34. Characteristics of Developing Economies • Population Growth and Population Structure • The concept of Optimum population. • As the population continues to grow we would expect the output per head to eventually peak and then decline as decreasing returns are experienced. At this stage the population has gone beyond the optimum and the country is considered to be overpopulated. • In real world, the situation is more dynamic and the state of technical knowledge is constantly improving. The quantity of the other factors also continuously changes so that the optimum population for a country is not a fixed entity. • In addition the criteria for assessing under- or overpopulation are purely economic and may be disputed by conservationists.

  35. Characteristics of Developing Economies • Income Distribution • It is a general characteristic of developing countries that income is unevenly distributed. • This is partly because income-generating assets, especially land, are owned by few • As a result there are great extremes of rich and poor. • The great extremes of rich and poor in developing economies means that deprivation is common.

  36. Characteristics of Developing Economies • Employment • Developing countries tend to suffer from higher levels of unemployment and underempolyment than developed countries • in countries with surplus populations the supply of labour tend to exceed the supply of the other factors of production. • Typically developing economies suffer from shortages in capital and entrepreneurial skills but in addition there is pressure on the supply of land suitable for the production process.

  37. Characteristics of Developing Economies • External Trade • The foreign trade of many developing countries tend to show a great reliance upon the export of primary produce. • Generally speaking developing countries depend upon primary products and developed economies depend upon manufactured goods. • When considering 45 countries included in the High Human Development category of the HDI, manufactures made up 80% of merchandise exports in 1997. • When considering 94 countries categorised as Medium Human Development, the average fell to 58% in 1997

  38. Characteristics of Developing Economies • External Trade • Very few countries categorised as Low Human Development had any significant manufacturing exports at all, since many of the population live at the margins of subsistence. • The significance of these data is that those developing countries that participate in international trade become reliant upon primary exports for foreign currency earnings. • This makes them vulnerable in their trading relationships because of the demand and supply conditions in the markets for primary products. • Demand of primary products tends to be price inelastic • Supply of primary products tends to be price inelastic.

  39. Characteristics of Developing Economies • External Trade • The supply of some are also subject to frequent shifts. • The market for primary products is subject to frequent and severe fluctuations in price. These fluctuations in price can de-stabilise the economies of developing countries. • In addition, the demand for man primary products especially foodstuffs is income inelastic,. As world incomes rise, there is little impact upon the demand for primary products as most of the higher incomes are spent on manufactured goods. • Over time there is a tendency for the terms of trade of primary goods to decline compared to manufactured goods.

  40. Characteristics of Developing Economies • External Trade • Therefore those developing countries dependent upon primary products are receiving relatively lower prices for their exports of primary products and paying relatively higher prices for imports of manufactured goods. • There has been a decline in the number of developing countries that are heavily reliant upon primary products as manufacturing sectors are established in some developing countries. • In others, principally in sub-Saharan Africa, there remains a heavy reliance upon a narrow range of primary exports.

  41. Characteristics of Developing Economies • Urbanisation • Developing economies still have high proportions of their populations living in rural areas. On average ver half of the population of developing countries are classified as rural. Nevertheless developing economies show very rapid rates of rural-urban migration. • High-income countries already have the majority of their populations living in urban areas. As a result there is little growth in the urban population of developed countries. • The rural-urban migration in developing countries can cause extra pressure on resources in already overcrowded urban areas. There is pressure on the infrastructure, with housing, roads and schools incapable of coping with the extra demand.

  42. Characteristics of Developing Economies • Technology • The gap between developed and developing countries in terms of the application of new technology is deep and widening. • This covers a wide range of applications including new production techniques, new more efficient means of communication and the electronic storage and retrieval of information. Only 5 per cent of the world’s computers are located in developing countries. • Although the application of the internet to commerce will increase efficiency, especially in distribution, it will widen the technology gap for those developing countries that lack the technical skills and the infrastructure to participate effectively

  43. Characteristics of Developing Economies • Summing up the common problems that stem from these common characteristics as follows: • Widespread and chronic absolute poverty • High & rising levels of unemployment/ underemployment • Wide & growing disparities in income distribution • Low and stagnating levels of agricultural productivity • Sizeable and growing imbalances btw urban and rural levels of living and economic opportunities • Serious and worsening environmental decay • Antiquated & inappropriate educational/health systems • Severe balance of payments and international debt problems • Substantial & increasing dependence on foreign & often inappropriate technologies, institutions & value systems

  44. Economic Growth & Developing Economies • Introduction • The PPC can be used to explain changes in the actual output of goods and services and changes in the potential output of goods and services • A change in the actual output of goods and services could e achieved by the better utilisation of existing factors of production. • Assume the economy is currently producing at point X within the PPF shown. Production at this point might be caused by a lack of aggregate demand in the economy. • The movement from point X to point Y on PPC can be achieved by increasing demand through fiscal and/or monetary policy.

  45. Economic Growth & Developing Economies • Introduction • This would lead to a increase in the output of both goods and services. In turn it would certainly lead to an increase in GDP and be considered as actual economic growth. • In the long run further increases in output could only be achieved if the potential output of the economy was to grow. • This would represented by a shift in the PC itself. The shift of the curve from PPC1 to PPC2 represents a growth in the potential output of this economy. • In the long run therefore explanation of economic growth need to focus upon those factors which increase the potential output of an economy.

  46. Economic Growth & Developing Economies Quantity of goods Potential output has grown Y · · X PPC1 PPC2 Quantity of Services An increase in the potential output an economy

  47. Economic Growth & Developing Economies • Factors contributing to economic growth • The position of the PPC is determined by an economy’s production function. This shows the maximum output that can be produced by an economy given the current endowment of factors of production and the current state of technical expertise. • In order to achieve sustainable economic growth over time it is necessary to: • Increase the quantity of resources at the disposal of the economy. • Increase the quality of resources at the disposal of the economy.

  48. Economic Growth & Developing Economies • Factors contributing to economic growth • Increase the quantity of resources at the disposal of the economy. • All factors of production can potentially be increased • In developing countries the supply of labour would grow through the natural increase in population. The population will grow if there is a positive net migration as the number of immigrants exceeds the number of emigrants. • An increase in the labour force will not create a great impact upon production possibilities without an increase in the other factors.

  49. Economic Growth & Developing Economies • Factors contributing to economic growth • Increase the quantity of resources at the disposal of the economy. • Capital goods can only be increased if investment takes place. • Enterprise can be increased through training and government policies that encourage risk-taking in the economy. • Land can only really be increased through conquest. • Any land gained through reclamation schemes should be considered as a type of capital because it needs investment before it becomes available.

  50. Economic Growth & Developing Economies • Factors contributing to economic growth • Increase the quality of resources at the disposal of the economy. • Improvements in the quality of resources will increase the productivity of the factor inputs. • The quality of labour can be improved through education & training, known as investment in human capital(also can be applied to any development of the factor enterprise) • The quality of capital goods is improved through time as technology improves. The quality of capital goods used in developing countries improves as these countries participate in international trade. • The quality of land for agricultural use can be improved through the application of fertiliser, and through irrigation and drainage schemes.
