Cost Benefit Analysis Economics Essay

Cost Benefit Analysis Economics EssayIntroductionCost Benefit Analysis (CBA) is a technique which seeks to bring greater objectiveness into the decision making. It is a well known evaluation technique that is extensively engaged by both public and private organisations to support the decision making process. It can be useful to almost any kind of decision in any kind of field. It is helpful to identify all the relevant benefits and woo of a limited scheme and to quantify them in m wizardtary terms. The practice arrived in the unite Kingdom in 1960s for use in the deportation sector. CBA techniques were extended to cover a wide range of coats, such as water resource management, motorways, nationalized industries, airport locations, forestry, recreational facilities and a wide range of urban investment draws (Paul, 2000).Private sector, direct financial costs and benefits determines the profitability and increases the output and investment. All costs and benefits in public sect or, affected by an investment must(prenominal) be evaluated in some other way. Welf be economics helps to resolve such issues as how to assess costs and benefits of a non-monetary environment how to assess the association benefits when no charge made for public facility and how to fiddle with the market failure.Cost Benefit AnalysisCBA rests on the recognition of a potential Pareto development. The reason for this is the proposition that, a decision is justified if those who benefit from it could compensate by those who lose by it. Compensation needs not really occur. What is essential is that the expenses of a policy to those who suffer the costs are exceeded by the value that beneficiaries place on it. This whitethorn still re main(prenominal) on an adequate basis for apprehension because CBA attempts to as certain(a) whether the resources are being used efficiently. It will often be the case that the occurrence of costs and benefits, i.e. who bears them, will moreover be ver y important. CBA whitethorn provide a framework designed to identify accurately where the costs and benefits fall, so that a governmental judgement may be completed as to their satisfactoriness.CBA is a widely used technique which evaluates public spending and aims to avoid inappropriate distribution of public resources. In theory, it helps public decision-makers to invest only in the projects that produce more profitability from the viewpoint of the community.To function perfectly, the CBA procedure needs to be engaged prior to the decision is made, so that the potential of the range of project proposals can be compared and evaluated. It aims to evaluate the set of direct and indirect effects of a project, its financial and non- financial effects on the set of economic agents refer with the investment. These effects are then synthesized, subsequently monetary evaluation, to assure a socio-economic balance which establishes the return on the investment, with this return being es timated on the basis of item indicators (Auzannet, 1997).According to Boardman et al. (2006) the major steps in CBA are as followsSpecify the set of choice projectsDecide whose benefits and cost countCatalogue the impacts and select measuring rod indicatorsPredict the impacts quantitatively over the life of the projectMonetize (attach dollar values to) all impactsDiscount benefits and costs to obtain present values practice sensitivity analysisMake a recommendationHistory and Uses of CBAAt present, CBA is being used in both government and international organization. While certain concepts of the technique oriented from Europe in 1840s, the use of CBA in environmental economics is relatively a new incidence which is becoming recognized after patterns were set by the US government. And this made the use of CBA compulsory in the 1930s (E.J. Mishan and Euston, 2007). It was used to generate a solution toward the problems of water provision. After domain of a function War II, there w as pressure towards the skill in government and the search was on for ways to make sure that the public funds were efficiently utilize in major public investments. This resulted in the beginnings of the fusion of the new welfare economics, which was essentially a Cost-Benefit Analysis and practical decision-making. This particular process arrived in the United Kingdom in 1960s in support of the transportation sector. It was applied to the construction of M1 motorway and the Victoria line on the belowground (Economic Labour trade Review, December 2008). In recent years, it is recognised as the major appraisal technique for public investments and public policy.Principles of CBAThere are eight basic principles under this CBA ((S.L. Kirama, 2010). These areThere must be a common unit of measurementCBA valuations should represent consumers or producers valuations as revealed by their actual behaviour.Benefits are commonly measured by market choicesSome measurements of benefits requ ire the valuation of human lifeThe analysis of project should involve a with or without comparisonCBA involves particular study areaDouble counting of benefits or costs must be avoidedDecision criteria projectsEmergence of CBACBA allows different projects to be ranked correspond to highest pass judgment net gains in social public assistance. This gives important limitations of government spending. The main stages in CBA approaches are (Geoff Riley, 2006),Calculation of social costs and benefits. This includes direct costs, indirect costs and the benefits predisposition analysis of event occurringDiscounting the future value of benefitsComparing the costs and benefitsComparing the net rate of benefitsThe Application of CBAIn the private sector, financial CBA is used to prune equipment and technology investment, measure life cycle costs, meet regulations cost-effectively and quantify hidden costs and intangible benefits. It is also useful to demonstrate how outsourcing and leasing can result in cost savings and how quality improvements can affect returns. Social CBA is being used to evaluate the social merit of projects or policies.In practice CBA deepen between countries and sectors within countries. The main differences include the qualitys of impacts that are being included as costs and benefits within the assessment procedure. This is an extent to which the impacts are expressed in monetary terms and difference in discount rate between countries. The public CBA may also vary from private CBA (S.L. Kirama, 2010). CBA is likely to have its main impost within the public sector where (J. Harve and E. Jowsey, 2004)Price signals are insufficient to guide investment decisionsSpill-over benefits and costs are important owing to the magnitude of the schemesThe wellbeing of unborn generations has to be allowedKey Concepts in CBAThere are some key concepts in CBA. There are present value, discount rates, opportunity costs, cost and benefits, discounting, net pre sent value, shadow prices, etc. (J. Harve and E. Jowsey, 2004).Government Decision- makingGovernment may take the form of regulation such as building regulation to reduce fire hazards, taxes or subsides or providing goods and services. The main difficulty in many public-sectors is that the goods are provided free of charge or below the market price. So they are forced to focus on short-term special effects of the financial system and the long-standing sustainability of the public finances.Government decisions depend on subjective political considerations. For example, obtaining a social mix council housing may be providing an expensive residential area. However, public investments have serious defects.The one-man, one-vote principle does not weight votes according to the intensity of welfare gain or lost. Therefore, majority of the decision allow two voters marginally in favour of a scheme to outvote one who strongly opposes it in spite of the fact that the sum of their benefits is less than the costs impose on the single opponent.Political decisions are important one-sided. Economic efficiency in resource allocation requires that objective criteria should be used as far as it is feasible.The extension of government involvement in the economy has increase the weight and complexity of decisions which needs to be made at government level. Many argument says that decentralisation of decision-making is desirable.Application to Construction IndustryGovernment is fundamentally responsible for roads, bridges, airports, parks, amenity land, new urban areas and housing. CBA is normally being favoured by many transportation economists. It assesses the entire benefits and costs associated with highway project, including both capital and exploiter costs. In this case, project requires less cost but provides more benefits right through the analysis period which are chosen first. CBA estimates the costs in monetary terms. Traditionally, a benefit-cost ratio, net present v alue or internal rate of return is being used. Recent research suggests that the net present value (NPV) may provide the best project selection measure if the transportation program is under financial constraints (Reed and Rutherford, 1997).The Use of Cost-Benefit Analysis in dose SectorTransportation policy and scheduling decisions often engage tradeoffs between conflicting objectives. Most highway cost allocation and investment evaluation studies are primarily refer with direct market costs, such as road construction and maintenance, travel time, vehicle operating costs and crash damages. These vary depending on vehicle type and roadway conditions. They assume that the total amount of vehicle travel does not change, so were unconcerned with vehicle ownership and parking costs. Other types of studies incorporate environmental impacts, primarily air pollution, but sometimes it also includes noise and water pollution, and various other categories of land usage impact. Some studies have only considered foreign costs avoiding the internal ones.CBA is extensively used within the transportation segment. CBA of transportation investment projects tend to neglect long-term environmental consequences and needs among the community class with a low ability to pay. It has been emerged as one of the most used tools in deciding the viability of proposed infrastructure projects. The predictions regarding the impact of such projects are often bad uncertain. The transport modelling tools are used in order to estimate positive as well as the negative impacts.Case Study Heathrow concluding 5In this case, the British Airport Authority (BAA) planning to build terminal 5 the cost is approximately around 4 billion. Planning application was submitted in February 1993 (Heathrow T5, October 2005). They were considering the following benefits, such asEconomic growth Demand for air travel in south-east England is forecasted to be doubled in the adjoining 20 years, making the r efinement seems to be essential within the Air travel industry. This in turn might create thousands of jobs and businesses depending on the Heathrow airport expansion in order to provide sufficient supply capacity to meet the growing demand. An increase in the capacity of Heathrow will make maximum usage of airports existing infrastructure and land.The economy and trade if it does not meet demand, UK will lose its airlines and foreign investments within the other European regions. The benefits of a world-beating industry would be reduced. Therefore, many sectors of our aviation industry will have a comparative advantage and might add huge sums to our balance of payments.Jobs This project will create job opportunities which are estimated to be around 16,500. And it may also create 6,000 construction jobs during the building phase. This will have multiplier effects on the local / regional and national economy.Transport The terminal will be the centre of a world-class transport exchan ge, with new Tube and rail links. Car affair would rise only slightly. The social costs of increased traffic congestion have been exaggerated by the environmentalists.Environment The site which has been allocated for terminal 5 is shortly a disused sludge works. And any displace wildlife and plant life will be carefully relocated. The noise climate around Heathrow Airport has been astir(p) for many years, even despite the fact that the number of aircraft movements has increased considerably partly due to the phasing out of older, nosier aircraft.Noise and night flight BAA promises no increase in boilersuit noise levels or in night flights. The number of flights will be increased by 8%.(Source http//tutor2u.net/economics/revision-notes/a2-micro-cost-benefit-analysis.html)Objections are being raised against this project but those were not enough to refuse the planning permission.ConclusionCBA provides a rational technique for the evaluation of projects where market information is e ither non-existent or deficient. But it should not make false claims for objectivity by dealing in precise sums. However it is helpful for decision-making purposes, it is not an alternative for it. Further, CBA is potentially a useful aid towards planning decisions and it does not avoid the need to make value judgements in the evaluation of intangible arising from different projects. The overall conclusions are to be drawn from the assessment of costs and benefits. However, such value judgements are made clear in the evaluation decision making process.
