Economic growth Essay

Economic harvest-tide refers to the extend in the levels of a countrys wealth and capital as a solvent of positive swap in the levels of production of goods and armed services during a certain(prenominal) period of clip. 1 Economic proceeds is normally ignited by technological feelers and positive external wads. Economic result can be measured either in terms of nominal exploitation or documentary harvest. Nominal harvest-tide takes inflation into account and then demonst desexualize ups scotch harvest-feast as Net Domestic Product while real harvest does non account for inflation and thus demonstrates frugalalal outgrowth as Gross Domestic Product.Economic growth is usually obstinate by levels of Gross Domestic Product (gross domestic product). gross domestic product is the preferred path of measuring economic growth because increase or decrease in the GDP levels in a country reflects the real the standards of living of its population. GDP is the total m arket esteem of all final examination products of all final goods and services explicated in a country in a presumption up yr expressed in m unmatchabley grade. 2 GDP of a country equals total consumer enthronements and government spending, plus the value of exports, minus the value of imports. As such, GDP can be summarised as follows GDP = expending + gross Investment + Government Spending + (Exports-Imports) or simply GDP = C+I+G+(X-M). However, it must be noted that economic growth entails more than just mere change over of collection plate of economic magnitudes. By its precise own personality, growth modifies economic structures at that placeby adjusting the commonplace technological and hearty dynamics in a country. Bourguignon points out(a) that economic growth may modify the firmamental structure of an economic unit, track to close plenty of firms in one sector and trigger of stark naked firms in another.3 Bourguignon further notes that growth modifies the structure of prices, thus affecting the standard of living in households in a expressive style that depends on their consumption preferences. 4 Moreover, economic growth calls for change magnitude technological innovations which in turn increases the necessity for change magnitude technological knowlight-emitting diodege and skills, a situation that would require increase investment in education and give away remuneration for holders of such important skills.The final and roughly important evaluate of economic growth is that it reduces the abundant availability of public goods such as adequate water supply and clean air due to increase pollution. Consequently, this may call for intervention and preventive measures in order to keep adequate supply of the environmental goods. Therefore, economic growth impacts on the frugality, social structures and environmental factors of a country. Therefore, people, as the human factors of economic growth stick roughly very importan t components of economic growth. piece economic growth is primarily driven by asseverate dynamics and machinery, the interactions within the societal material bear consequential impact on the manner in which economic growth may either be beneficial or bruising to the semipermanent interest of the people. 5 Therefore, the pursuit of economic growth presents as much benefits as threats to the long-term interests of the people. The different principles and models of economic growth ar best demonstrated by different existing theories of economic growth. 1. J.

Helpman, The mystery of economic growth, Cambridge Harvard University, 2004, p. 7 Theoretic al background Although there argon many theories and models of economic growth, the exogenic possibility of economic growth and the endogenous supposition of economic growth provide the most acute theoretical background on issues concerning economic growth.The exogenous scheme was innovative by the neo-classical theorists while the endogenous theory was advanced by the red-brick economic theorists. The exogenous theory of economic growth was advanced by Robert Solow and Trevor Swan. The theory states that long-run rate of growth of a system is fit(p) by guides outside the system. 6The main prediction of this theory is that an economy pull up stakes of all time converge towards a steady state of growth which depends absolutely on the rate of technological progress and growth of get the picture.The theory is based on a series of equations which demonstrate the relationship in the midst of labour, time, capital goods, output and investments. The main argument of the exogenous growth theory is based on the assumption that capital expansion is subject to diminish returns. Therefore, given a fixed amount of labour force, the impact on the output of the last unit of capital accumulated bequeath always be less than the impact on the preceding units. 7 This wheel around continues to a point where new amounts of technological progress and labour force adds no new value to capital produced.New technological innovations and labour force output but serve to replenish the loss of value to existing capital due to depreciation. Solow and Swan refer to this as unchanging state of growth. Modern theorists such as Barro, Ormerod, and Romer disagreed with the idea of static state of growth subject to diminishing returns as advanced by the exogenous theorists. They therefore developed a more relevant and realistic theory that came to be referred to as the endogenous theory.Proponents of endogenous growth theory beseech that comparisons mingled with trends of produ ction in industrialised countries today and before industrialization reveal that growth was generated and sustained by forces within as foreign to forces outside the countries. The endogenous theory states that economic growth is generated from within a system as a direct result of internal processes. 8 according to the endogenous theorists, improvement in productivity can be linked to a faster pace of innovation and committed investment in human capital.The theory notes that the enhancement of a nations human capital will convey to economic growth by means of the cultivation of new form of technology that will lead to efficient and sufficient means of production. 9 The main digest of the endogenous theorists lies on the need for both government and private sector institutions to nurture innovations through incentives that will encourage individuals to be innovative. As Romer points out, the rate of technological progress should not be taken given in a growth model, but rather, appropriate government policies fuddle to be applied in order to raise a countrys growth rate.10Such policies should positionly be targeted towards creating in high spiritser levels of competition in markets and greater innovation initiatives among individuals. Endogenous theorists identify private investment in research and development as universe the key driving force for technical progress. Furthermore, protection of property rights and patents can provide the incentive to take over in research and development. 6. R. M.

Romer p. 81 wherefore the pursuit of economic growth is not in peoples long-term interest Concerns to the effect that the pursuit of economic growth is not in peoples long-term interest are very much valida ted by the current worrying trends of economic growth. While proponents of economic growth cite many benefits associated with economic growth, such benefits only stand to serve peoples short-term interests.It is increasingly beseeming apparent that just like the past, the current economic growth initiatives are being undertaken with little regard to long-term repercussions of such initiatives. One of the most important long-term interests that economic growth should guarantee is the safety and saving of the ecosystem, which will in turn guarantee peoples long-term interests. To the contrary, the aspects of the safety of natural resources and the environmental preservation are the most treat by economic growth.Yet, the gradual destruction of the environment harbours the risk of ultimate destruction of the planet earth. Without action on climate change, economic growth and development are likely to generate levels of greenhouse hired gun firing offs that would be very damaging. 11 Economic growth is evidently increasing the take away for fossil-fuel talent, thus the failure to implement appropriate international collective actions will allow manufacturers and consumers to continue with their risky energy consumption behaviours, thereby be greater threats of adverse climatic change.Adequate supply of the environmental goods is liner continuous challenges as economic growth continues to wreck havoc on the environment. The female genital organ Review Report on the Economics of Climate spay (2006) identified that the world ecosystem is facing threats of eminent destruction due to increased levels of greenhouse emissions to the atmosphere. According to the low aliveness Report, greenhouse-gas submergings in the atmosphere stood at around 430 CO2 equivalents as of 2006, compared to 280ppm before industrial revolution.12The whelm pollution is as a result of combined forces of emissions of toxic gases from the power sectors, transport sectors, mental syn thesis sectors, industry sectors, land use sectors and land use sectors throughout the world. Indeed, these particular sectors represent the key driving forces of economic growth. As pointed out in the turd Report emissions tolerate been driven by economic development. coke dioxide emissions have strongly been correlated with GDP per head across time and countries.North America and Europe have produced around 70% of atomic number 6 dioxide emissions from energy production since 1850, while developing countries account for less than one quarter of cumulative emissions. 13 Annual emissions are increasing at constant rates year after year. Between 1950 and the year 2000, emission of Carbon dioxide which accounts for the largest share of green house gases, grew by 2. 5% annually. 14The Stern Report further warns that without action to combat climate change, atmospheric concentration of green house gases will continue to rise.In a credible business as usual scenario, they will reach 555ppm CO2e by the year 2035. 15 Moreover, total emissions are define to increase more cursorily than emissions per head in tandem with the projections that planetary population will bear on positive until 2050. 11. Stern Review continue on economics of change, opposition of climate change on growth and development, November 2006, p. 169 12. Greenhouse gases are usually converted to a common unit, CO2 equivalent, which measures the amount of carbon dioxide that would produce the same global warming potential (GWP) over a given period as the total amount of greenhouse gas in question.13. Stern Review report on economics of change 14. Stern Review report on economics of change 15. Stern Review report on economics of change These are the most imposing revelations concerning the gradual and unabated destruction that economic growth is imposing on the environment The approaching generations remain exposed to the risks of frequent disasters that are associated with global warming. Such risks include food and water shortages, increase air pollution, increased desert cover, rise in sea levels as surface as increased frequencies of tornadoes and tsunamis.Obviously, such threats of climatic change will impact negatively on population growth and living conditions for the people in future. confuse 1 demonstrates a variety of experiences across different countries of the world. The EU and the economies in transition reported considerable reduction in carbon military posture during the period. However, India went against the grain and substantively increased carbon emissions during the same period. Developing countries registered significant growth in populations as well as growth in GDP per head.Equally notable is the tremendous decrease in the energy intensity of output in India and China. This table clearly demonstrates that despite the high levels of emissions, many countries undertook important economic reforms in the 1990s, a move that led to marked impro vements in utilisation of energy, with many countries registering significant reductions in wasteful use of energy. Risks posed by economic growth are set to reduce with increased adoption of energy efficient production strategies that will underwrite environmental conservation while not hurting long-term growth rate targets.Why the pursuit of economic growth is in peoples long-term interest Despite the many reservations that opponents of economic growth have, there exists a general consensus that economic growth is a prerequisite requirement for the well being of the current and future generations. The future can only be secures through persistent creation of wealth and capital. Industrial revolution is credited for having ignited economic growth and ultimate improvement of living standards.The significance of industrial revolution is best captured by the Malthusian theory of economic growth which argues that industrial revolution and advancement in medicine translated to increas ed life expectancy and reduced baby mortality. 15 15. R. Lucas, lectures on economic growth, Cambridge, Harvard University Press, 2002, p. 49 According to the Malthusian theory, this industrial revolution culminated to increased income and population growth and eventual increase in income per capita in industrialised counties, and lasted for many years thereafter.16Therefore, economic growth remains a very important component sustained development of both current and future generations. Conclusion It is evident that economic growth also corresponds to processes of rapid replacement and reorganisation of human activities as well as natural resources, all in the spirit of investment and maximation of returns. As such, this realisation of the exponential abilities of the human race, as facilitated by self-organised life support and cultural systems, is a hinderance of the creative and flexible nature of human beings which however, is highly unpredictable in many ways.17 environmental threats posed by economic growth not withstanding, economic growth remains an important transition that this world must undergo. Therefore, the challenges posed by economic growth can best be tackled through creation of a balance between the conflicting concepts economic growth and mitigation of risks posed by economic growth. Economic growth is a saying of technological change. Yet the essence of technological modernity is non-stationery many scholars have acknowledged that technological change has become self propelled and autocatalytic, whereby change feeds on change.Thus unlike other form of growths, technology is not bound from above. Inventions have become a norm thus are unbeatable by forces of any nature. 18 The stern Report acknowledges that the relationship between economic growth and CO2 emissions is not immutable. There are functional examples where change in energy technologies, the structure of economies and the pattern of demand have reduced the responsiveness of emissions to income growth, particularly in the richest countries. Strong deliberate form _or_ system of government choices will be needed, however, to decarbonise both developing countries on the scale required for climate stabilisation.19 This is in itself a confirmation that effective protection and conservation of the environmental goods can be achieved tremendously through the adoption of energy efficient production strategies that will ensure environmental conservation while not hurting long-term growth rate targets. However, wide reaching strategies should be employed in the stately cause of environmental protection. Strategies that are over reliant on reduction of fossil fuels may not be enough to stop the overwhelming emissions of poisonous gases.Other strategies such as radical shift shifts towards service based economies have proved effective in slowing down or reversing the increase in emissions of poisonous gases to the atmosphere. 20There should also be increased l obbying for the adoption of the Kyoto Protocol of Climate Change by all countries in the world, including the United States. Being the worlds largest economy, the United States releases the highest amounts of toxic gas emissions to the atmosphere, yet the country has refused to recognise the Kyoto protocol which seeks to protect the world from being further exposed to the threat of climatic change.16.
