How to Use the Z.TEST Function in Excel

Hypothesis tests are one of the major topics in the area of inferential statistics. There are multiple steps to conduct a hypothesis test and many of these require statistical calculations. Statistical software, such as Excel, can be used to perform hypothesis tests. We will see how the Excel function Z.TEST tests hypotheses about an unknown population mean. Conditions and Assumptions We begin by stating the assumptions and conditions for this type of hypothesis test. For inference about the mean we must have the following simple conditions: The sample is a simple random sample.The sample is small in size relative to the population. Typically this means that the population size is more than 20 times the size of the sample.The variable being studied is normally distributed.The population standard deviation is known.The population mean is unknown. All of these conditions are unlikely to be met in practice. However, these simple conditions and the corresponding hypothesis test are sometimes encountered early in a statistics class. After learning the process of a hypothesis test, these conditions are relaxed in order to work in a more realistic setting. Structure of the Hypothesis Test The particular hypothesis test we consider has the following form: State the null and alternative hypotheses.Calculate the test statistic, which is a z-score.Calculate the p-value by using the normal distribution. In this case the p-value is the probability of obtaining at least as extreme as the observed test statistic, assuming the null hypothesis is true.Compare the p-value with the level of significance to determine whether to reject or fail to reject the null hypothesis. We see that steps two and three are computationally intensive compared two steps one and four. The Z.TEST function will perform these calculations for us. Z.TEST Function The Z.TEST function does all of the calculations from steps two and three above. It does a majority of the number crunching for our test and returns a p-value. There are three arguments to enter into the function, each of which is separated by a comma. The following explains the three types of arguments for this function. The first argument for this function is an array of sample data. We must enter a range of cells that corresponds to the location of the sample data in our spreadsheet.The second argument is the value of  ÃŽ ¼ that we are testing in our hypotheses. So if our null hypothesis is H0:  ÃŽ ¼ 5, then we would enter a 5 for the second argument.The third argument is the value of the known population standard deviation. Excel treats this as an optional argument Notes and Warnings There are a few things that should be noted about this function: The p-value that is output from the function is one-sided. If we are conducting a two-sided test, then this value must be doubled.The one-sided p-value output from the function assumes that the sample mean is greater than the value of  ÃŽ ¼ we are testing against. If the sample mean is less than the value of the second argument, then we must subtract the output of the function from 1 to get the true p-value of our test.The final argument for the population standard deviation is optional. If this is not entered, then this value is automatically replaced in Excel’s calculations by the sample standard deviation. When this is done, theoretically a t-test should be used instead. Example We suppose that the following data are from a simple random sample of a normally distributed population of unknown mean and standard deviation of 3: 1, 2, 3, 3, 4, 4, 8, 10, 12 With a 10% level of significance we wish to test the hypothesis that the sample data are from a population with mean greater than 5. More formally, we have the following hypotheses: H0: ÃŽ ¼ 5Ha:  ÃŽ ¼ 5 We use Z.TEST in Excel to find the p-value for this hypothesis test. Enter the data into a column in Excel. Suppose this is from cell A1 to A9Into another cell enter Z.TEST(A1:A9,5,3)The result is 0.41207.Since our p-value exceeds 10%, we fail to reject the null hypothesis. The Z.TEST function can be used for lower tailed tests and two tailed tests as well. However the result is not as automatic as it was in this case. Please see here for other examples of using this function.

The Syrian Refugee Crisis Is An Outcome Of The Civil War

POLICY MEMORANDUM #1 To: Dr. Ban Ki-moon, United Nations Secretary General From: Dr. Amena Al-Diri, Strategic Advisor to OCHA-Syria Subject: Proposal to solve the Syrian civil war in the UN Security Council Date: 09/22/2015 _____________________________________________________________________________ Executive Summary The Syrian refugee crisis is an outcome of the civil war that has suffered this country over four years. Therefore, a solution to this conflict is urgently needed to stop the humanitarian tragedy and the flood of refugees. In Syria’s civil war, the critical mass participation of local and international actors, with different priorities, perceptions and interests, has dramatically reduced the likelihood of a negotiated or military solution. In this context, the United Nation Security Council is the most suitable and pragmatic space to lead and seek for a multilateral solution, instead of continuing with these failed unilateral or bilateral military interventions that have taken place in Syria. The UN Security Council should promote a converging and problem-solving approach between Russia, the United States and other regional powers involved in Syria’s crisis, like Saudi Arabia and Iran; and then try to negotiate with the Government, rebels and paramilitary groups, as wel l as define an international strategy to defeat Jihadists.

Is the Life-Span Approach Essential to Human Development

Human development has been a subject of interest among modern researchers. The most prominent theory in human development is the life-span approach which is made up of various concepts. This essay aims to show the importance of the life-span approach by analysing some of the concepts that make up this approach, such as multi-directionality historical location and contexualism among others. This essay will critically analyse some of the assumptions of the life-span approach. It will also examine arguments against the lifespan approach as well as other theories of human development such as Freud’s psychoanalytic theory with the aim of showing that this approach is essential for understanding human development. One of the major assumptions†¦show more content†¦In southafrica research shows that black children who lived during the apatheid era ended up in sqatter camps without any aducation, with poor sanitation no recreation facilities and high health risks, this forced some to join ganges.

It has also been brought to attention that the research methods used by life-span researchers are to some extent unreliable and may produce inaccurate information.

The direct effects of Johnes disease Free Essays

Introduction Mycobacterium avium races paratuberculosis ( MAP ) is the causative agent of an incurable, infective, chronic, granulomatous enteritis in ruminants, called Johne ‘s disease or paratuberculosis. The direct effects of Johne ‘s disease on animate being public assistance and productiveness may look insignificant and are frequently masked by the mostly subclinical character of the disease in domesticated farm animal ( incubation period prior to the oncoming of clinical marks by and large ranges from 2 to 10 old ages ) { { 1 Lepper, A.W. We will write a custom essay sample on The direct effects of Johnes disease or any similar topic only for you Order Now 1989 } } { { 2 Chiodini, R.J. 1984 } } .The economic impact of JohneA?s on dairy cowss industries is significant. Estimated costs as a consequence of reduced weight addition, milk production loss, premature culling and decreased carcase value add up to an one-year sum of $ 250 million ( USD ) in the United States industry entirely { { 3 Ott, S.L. 1999 } } . More recent in-depth estimations indicate a important relationship being between Johne ‘s disease position and decreased milk production { { 51 Smith, R.L. 2009 } } , increased hazard of being culled { { 40 Smith, R.L. 2010 } } and a reduced calving rate in high sloughing animate beings. The on-going contention refering the possible function of MAP in Crohn ‘s disease ( human inflammatory intestine disease ) suggests that MAP itself might be of great public wellness significance { { 17 Hermon-Taylor, J. 2000 } } . 1.2. Transmission of MAP Cattles are most susceptible to infection as calves from birth to a few months of age { { 27 Taylor, A.W. 1953 ; 55 Windsor, P.A. 2010 } } , but can besides be infected as grownups { { 28 Doyle, T.M. 1951 } } .Transmission of MAP can happen by a assortment of paths in dairy cowss ; horizontally by consumption of MAP from the environment, or vertically from dike to calf. Evidence of intrauterine transmittal and sloughing of MAP in milk and foremilk has been reported by several surveies { { 5 Nielsen, S.S. 2008 ; 25 Seitz, S.E. 1989 ; 24 Sweeney, R.W. 1992 } } . Although calf-to-calf transmittal has besides been demonstrated in several experimental scenes where calves are being housed together { { 52 RANKIN, J.D. 1961 ; 53 new wave Roermund, H.J. 2007 } } horizontal infection from cattles to calves and perpendicular infection from dike to calf are believed to be the most common and most of import infection paths in dairy cowss. Previous surveies besides describe that calves born from positive tested dikes were at a significantly higher hazard of going Map infected than calves without this risk-profile. Besides calves turning up with a future high spiller and calves being born shortly following the freshening of an septic dike were at higher hazard being infected { { 29 Benedictus, A. 2008 } } . 1.3. Treatment A ; control Presently, there is no satisfactory intervention for the disease. No disinfectants are approved for the intervention of Johne ‘s disease because of their deficiency of efficiency and their failure to supply bacteriological remedy. A vaccinum for Johne ‘s disease exists but is non really normally used because it interferes with the reading of the current TB tegument trial and its inability to wholly forestall infection { { 44 Muskens, J. 2002 } } . Consequently JohneA?s disease is presently controlled via control plans that implement a assortment of production patterns. The most cost-efficient option for cut downing the prevalence of MAP infection in herds is application of hazard direction steps to interrupt known transmittal paths { { 6 Groenendaal, H. 2003 ; 16 Kudahl, A.B. 2009 } } . Current MAP control plans are risk-based. Management-wise, animate beings are divided into high and low hazard animate beings, by looking at the consequences of 4 one-year showings that test all lactating cattles for MAP specific antibodies in the milk { { 47 Nielsen, S.S. 2011 } } . Particular production pattern recommendations are provided for pull offing bad animate beings and these recommendations chiefly focus on within-herd MAP transmittal { { 46 Nielsen, S.S. 2007 } } .According to recent surveies, implementing patterns that can minimise the exposure of MAP to newborn calves should take precedence in control plans { { 45 Pillars, R.B. 20 11 } } . However, control steps are really expensive and non cost-effective. Current control steps do non take into history that MAP can be transmitted vertically and ignores the possibility that there is familial fluctuation in cowss associated with differential susceptibleness to Johne ‘s doing girls of septic dikes more likely to be infected even if hygiene steps are implemented absolutely at birth. 1.4. Heritability of susceptibleness Considerable work on linkage between genetic sciences and the opposition, tolerance or susceptibleness to Mycobacterium avium races paratuberculosis. Heritability of susceptibleness to infection with MAP has been estimated from 0.06 to 0.159 { { 18 Koets, A.P. 2000 ; 31 Mortensen, H. 2004 ; 37 Hinger, M. 2008 ; 38 Attalla, S.A. 2010 } } . The broad fluctuation in these extimates can be explained by differences in definition of infection and nosologies ( blood or milk ELISA, faecal civilizations, tissue civilizations ) , sample sizes, survey population ( breed ) and statistical theoretical accounts ( assorted animate being theoretical account, beget theoretical account ) used. Two genome-wide surveies have identified venue for resistence or susceptibleness to infection by MAP utilizing Illumina Bovine SNP50 assay { { 32 Settles, M. 2009 ; 33 Minozzi, G. 2010 } } . A SNP on chromosome 9 ( BTA9 ) is associated with casting ( being faecal civilization positive ) when genuinely infected ( tissue civilization positive { { 32 Settles, M. 2009 } } and being ELISA positive { { 33 Minozzi, G. 2010 } } . Zanella et Al. performed an association survey on the same dataset as Settles et Al. and found BTA6 to be associated with tolerence to paratuberculosis { { 43 Zanella, R. 2011 } } . Several campaigner cistrons identified by these genome-wide surveies have been examined for farther association with infection. Attempts to turn up cistrons associated with susceptibleness or opposition to paratuberculosis hold had limited success. Pinedo et al 2009 identified an association of caspase enlisting sphere 15 ( CARD15 ) with infection { { 34 Pinedo, P.J. 2009 } } , while a separate comparative analysis of bovine, murine, and human CARD15 transcripts suggest no important associations between fluctuation in the CARD15 and disease position { { 41 Taylor, K.H. 2006 } } .Toll-like receptor 4 ( TLR4 ) was associated with infection in recent work by Mucha et Al. 2009 but was non associated with infection in a coincident independent analysis { { 49 Pinedo, P.J. 2009 } } . Tendency towards association between infection and variant allelomorphs of the SLC11A1gene ( once NRAMP1 ) { { 34 Pinedo, P.J. 2009 } } is consistent with a population-based familial association survey carried out by Ruiz-Larranaga et Al. { { 42 Ruiz-Larranaga, O. 2010 } } , but conflicting consequences were presented by a population ba sed association survey by Hinger et Al. 2007 { { 39 Hinger, M. 2007 } } . Hinger et Al. and Minozzi used ELISA-tests as a diagnostic step to sort animate beings as septic whereas Pinedo et Al. used a combination of ELISA and faecal civilization to specify infection and Settles et Al used faecal and tissue civilization. The complexness of the intracellular infective disease Mycobacterium avium races paratuberculosis causes suggests engagement of many different cistrons that perchance interact with one another and with external factors from the environment. In add-on, the different procedures involved in early disease and late disease are yet ill-defined and may besides be reflected in the different venue found to be associated with the categorization of the type of infection. Particularly because pathogenesis of the disease is non to the full understood and sensitiveness of ELISA trials is rather low in latent or low casting animate beings { { 10 McKenna, S.L. 2006 ; 54 Eamens, G.J. 2000 } } { { 50 Nielsen, S.S. 2008 } } , case-control association surveies that use chiefly tissue and fecal nosologies in order to find the true infection position of the cow present the most dependable consequences. 1.5. Vertical transmittal To look into the importance of perpendicular transmittal, old surveies tried to find the prevalence of foetal infection in cowss and estimated the incidence of calves infected via in utero transmittal. On norm, approximately 9 % of foetuss from subclinically infected cattles ( faecal civilization positive ) and 39 % from clinical cattles were infected with MAP prior to deliver { { 4 Whittington, R.J. 2009 } } . Harmonizing to Whittington and Windsor { { 4 Whittington, R.J. 2009 } } existent prevalence of foetal MAP infection would be higher than reported because some of the methods and protocols used in these surveies to handle and prove samples have really low specificity { { 54 Eamens, G.J. 2000 } } . The estimated incidence of calf infection derived via the in utero path depends on within-herd prevalence and the ratio of sub-clinical to clinical instances among septic cattles. The mean perpendicular infection rates mentioned above are derived from the consequence of five independent surveies published between 1980 and 2003. 1.6 Strain typewriting Current developments in molecular genetic sciences make it possible to disciminate Mycobacterium avium paratuberculosis strains with different fingerprinting techniques { { 36 Motiwala, A.S. 2006 } } . These techniques can besides be used as a tool to look into the possibility of perpendicular transmittal by comparing strains carried by the dike with strains carried by the girl. When comparing different MAP fingerprinting techniques, the Multi Locus Short Sequence Repeat technique utilizing all 11 venues selected by Amonsin et Al. 2004 has the highest prejudiced power with a Simpsons diverseness index of 0.967 { { 36 Motiwala, A.S. 2006 } } . Harris et Al. 2006 used four of these identified repetitions ( locus 1, venue 2, locus 8 and locus 9 ) to distinguish MAP strains { { 21 Harris, N.B. 2006 } } . To analyze diverseness of the selected MAP isolates we used these same four venue for MLSSR analysis and added venue 3, venue 5, venue 6, locus 10 and locus 11 in order to observe more diverity among dam and daughter isolates. Strain typing methods to longitudinal datasets can now supply us with extra penetration into within herd infection kineticss, including the transmittal of MAP from dikes to girls.

Evidence Based Decision Making Administrators and Professionals

Questions: 1. How readily can the concepts of evidence-based decision making be applied in the strategic decision making of health service management executives? Justify your arguments. 2.What leadership style(s) is/are most suitable to manage strategic changes in health care? Justify your answer which includes providing examples of strategic health changes. Answers: 1. Evidence based decision making process can be implemented with the strategic decision making in a health care organisation, with objective of maintaining work continuity and achieving effectiveness in care delivery (Lgar, 2014). Health care executives, administrators and professionals uses the evidence from various researches to implement their opinion, knowledge, and perspectives within their decision-making process of routine care delivery. This concept of clinical services has become an integral part of health care centres all over the world, owing to the fact of proven efficacies in care outcomes, which has been further explained with an example, that can provide clear understanding. Use of evidence-based decision making helps the managers to make strategic planning about how to organise, deliver and operate the health services (Lgar, 2014). For instance, the Australian government uses demographic information, population dynamics, incidence of diseases, and effectiveness of medication (post-marketing surveillance) within the pharmaceutical companies, which allows easy access of the prescribed medicines for community. The measure is also effective in terms that it makes the medication production, cost effective (due to presumed market demand) (Alonso-Coello, 2016). Another example illustrates Australian childhood immunization register which uses the evidence based vaccination policy. According to their earlier statistics, the estimated cost for the vaccination for childhood immunization was supposed to increase from $6 million annually to around $60 million. Here in this case population based observational information was used in determining the increased profit, in conjunction to the expanded vaccination policy (Barry Edgman-Levitan, 2012). The above-mentioned example thus illustrates how the evidence based decision making process renders cost effective solution to manage the health requirement of Australian community, thereby also offering access to medication and immunisation requirements. Similarly, in another case of Australian medical care related to optometrists, the above technique of evidence-based decision making has been used. This clinical practice here includes the diagnosis, analysis, and supervision of dry eye. The Australian optometrists mostly used the phenol red test and tear osmolality test based on the research evidence data of dry eye (Alonso-Coello, 2016). These primary sources of evidence further helped the optometrist practitioners in their routine clinical services that in turn is reflective with optimal standards in managing care delivery of commonwealth. A statistical analysis was done on Australian women suffering from polycystic ovary syndrome (PCOS) based on the evidence based guidelines, which was subsidized by the Government of Australia (Department of health and ageing). According to the evidence, about 21% of the Australian reproductive-age are facing PCOS, and mostly who are weighty. Thus, in the year 2003, a conclusion was made on PCOS by the Rotterdam consensus workshop based on the guideline and according to it, ultrasound of either oligo or anovulation and polycystic ovaries is implemented as an effective diagnostic tool. Similarly, another such instance was seen in the year 2003, where the national health and research council of Australia provided the evidence based guidelines for the acute low back pain (LBP) to every Australian practitioner. According to the evidence the practitioners supported either of the two methods, that is conducting x-ray if fracture is detected and another is providing appropriate treatment. While it should be noted that practitioners should not implement these evidences blindly, rather they should do proper research and study before implementation in routine services (Melnyk, Gallagher?Ford, Long Fineout?Overholt, 2014). Thus, these examples, explain how the evidence-based decision making is helpful in managing the standards of care delivery and managing customer satisfaction. 2. Change is the key to success for every organisation, especially the health care organisation, where strategic changes have potential to manage the effectiveness and brings positive outcomes. The change can be in the form of structure of the health care departments or in the selection of the treatment procedure, or in the treatment instruments. In this regard, it is noteworthy to mention that the implementation of the change or the innovation might not work properly, because of the wrong implementation procedure (Daly, Jackson, Mannix Hutchinson, 2014). Thus, in a health care organisation proper management and implementation of the change is a matter of key concern which needs to be handled effectively by the medical leaders. For a successful strategic health change management, the medical leader has to properly evaluate, plan and implement the necessary actions and strategies needed. Additionally, the proper coordination of medical leaders and other health care staffs is requisit e to implement the change successfully. The various leadership qualities needed for efficient strategic change management are: Charismatic leadership- In a health care management, a medical leader should be charismatic in order to drive transformation among the medical staffs to successfully implement change in the department. They give new strategic view and preview its positive outcomes to gain maximum support from the staffs (Fulop Mark, 2013). They identify their staffs needs, which includes doctors, nurses, technicians, pharmacists and other employees and bring the change accordingly. Notably, in some cases the patients also disagree to implement the change in the health care system to avoid the risk factor. Thus, a charismatic leader can only direct them towards the change with the use of communication, mentor relationship, and visionary for long term benefits. Visionary leadership- A visionary medical leader has the potential to change the vision of implementation into reality. This leadership style helps in proper evaluation, analysis of the outcomes, and manages the results from the change implementation into visionary objective. Notably, the visionary leader has characteristics of making use of evidences in strategic change plans and also have effective communication skills to convince others (Hurley Hutchinson, 2013). Transformational leadership- The transformational medical leader will always try to initiate change in the health care system by virtue of their perspectives, wisdom, evidence, and justified rationale. They motivate the medical staffs, the senior management and the patients to follow and implement the change in the medical procedure, which in turn is always effective in managing the standards of outcomes (Sebastian, 2014). They use challenging steps to get the higher result in course of time, which marks their attitude of strategic decision making distinct from other leaders. Strategic leadership- A strategic leader within health care settings is generally the head of the organisation, who is always willing to provide change in the research, procedures and medicines. The leaders should provide proper medical training to the doctors and nurses to adopt the new procedures. Note that strategic leader always make use of evidence in the process of strategic planning (Hurley Hutchinson, 2013). Likewise, they also put emphasis on the training and education related framework to bring optimal competency level in their employees. Correspondingly, they also make rationalised usage of evaluation and monitoring framework to achieve efficacy in their implemented strategic changes. References: Alonso-Coello, P., Schnemann, H.

Fuel Tax Essay Example

Fuel Tax Essay Example Fuel Tax Essay Fuel Tax Essay Do you just want cheaper fuel to increase your income? To become a popular Government? Squeeze more profit for your firm? Protect the environment? Break car dependence? These questions are a sign of the ever-increasing pressure for and against a reduction in fuel tax. The governments reluctance to openly discuss its policy has caused a real clouding of the arguments causing a general sense of frustration. This essay addresses both sides of the arena in the pursuit of bringing clarity and reason to an emotional topic. This essay uses the term petrol as defined to be a flammable fuel used in internal combustion engines(Oxford Con Dic, 1989: 425), thus including diesel, as well as unleaded vehicles. The issues that are covered are externalities, tax, public transport, who the tax effects, and utility. The arguments are ordered against a reduction then for a reduction. Over the last 30 years, with the rise of environmental awareness, the externalities connected with the use of motor vehicles have caused major concern to society and has presented a strong argument against a reduction in petrol tax. Pigovian taxes are the best way to correct for the negative impact of externalities by taking into account the social costs of using petrol to such a great extent. These social costs: health, congestion, environmental breakdown and accidents all need correcting. Every time you burn petrol you generate pollution in the atmosphere with carbon dioxide, thus increasing global warming and health problems e.g. asthma, bronchitis, and other respiratory disorders. Congestion causes lost opportunity costs from unproductive time wasted. Accidents cannot be measured accurately as the loss of intellectual productivity cannot account for future possibilities. The best way is to allocate efficiency with social cost added to the pricing model. : As we see in figure 1: The marginal private cost curve is MPC. D is also the marginal benefit curve. Marginal cost exceeds MPC. In a competitive market, output is Qo, price is Po. When a Pigovian tax is imposed to show the social costs, then MSC becomes the MC for suppliers decisions. The price rises to P1 and the quantity falls to Q1: the point of allocation efficiency (Parkin, King 1995: 527). With the market failure and the externalities addressed the government can gather the tax revenue and tackle the social costs with revenue generated, which brings the price into alignment with their external costs. To look closer at the nature of tax and its winners and losers will reveal that all the tax is past onto the consumer in accordance with its inelastic properties. As the rules of tax state, with the fall in quantity demanded being smaller than the price reduction (in percentages). The consumer will be saddled with the larger cut of tax in the short run and all the tax in the long run. Therefore, the consumer is paying for all the externalities and the firm that profits from supplying petrol: pays nothing. As seen above in figure 1, there is a dead weight loss, which is caused from the reduction in the quantity demanded. This welfare loss has been minimized, however, this shows the petrol sectors ability to sustain large tax increases. The lack of response by motorists to the increases in the price of petrol causes the tax to become very appealing for revenue generation. The quantity demanded does not drop much after a tax increase. This shows how large amounts of money can be raised easily. In 1999/2000, fuel duties (excluding VAT) raised à ¯Ã‚ ¿Ã‚ ½22.3 billion, which is 6% of the total governments revenue (HM Treasury 46: 2000). The market for fuel is able the bear a large tax charge and the extent of the market is sizable too. Six pence on all road fuel duties raises as much money as one penny on the basic rate of income tax (HM Treasury 44: 1999). The suppliers and the government are seen to raise huge amounts of revenue from highly taxed petrol. In response to the argument for a reduction in petrol tax as the large amounts of revenue generate seem excessive and appear to be public and private profiteering. With the revenue being re-invested in infrastructure as the government is committed to doing. In the Chancellors Pre-Budget Speech in November 1999, [we] are now in a position instead of the pre-announced 6 per cent escalator-to make our decisions Budget by Budget with the following commitment: if there are any real term rises in road fuel duties, the revenues will go straight to a ring-fenced fund for the modernisation of roads and public transport (Smith, 2000; 8) These pledged billions give the vehicle user a real choice. The need to break car dependency and shift back the demand curve back instead of a taxing shift along the demand curve will reduce drivers by more. See figure 2: The option of substitute transport will make the driver fell they do have a choice to private vehicles. Investment of the revenue from petrol tax is a great asset. Much more than the revenue from the mandatory car tax gives. These improvements are necessary, as the infrastructure needs modernizing. This alternative will drop demand by giving a substitute drivers can rely on. The haulage industry will use it to put its freight back on the railways, if confidence were restored. A solid public transport system reduces demand without tax by using the revenue to change behaviour on petrol reliance. People are not adverse to tax increases if they know where the money is being spent. There is no way to guarantee that the money allocated to spending on roads and public transport is actually going to be spent in these areas. With the state of the rail system, the amount of congestion and the crackdown on accidents by fines, which many see as a new source of revenue, we are not seeing the benefits from the high petrol taxes: the highest in Europe. See figure 3: Unleaded petrol UK 55.47 Netherlands 44.84 Italy 42.93 Germany 40.12 Austria 32.35 Spain 28.04 Figure 3. European petrol duty and VAT, pence per litre With these high prices drivers expect to see improvements. This is the essence of their frustration. The modernization the government speaks of has not shown many tangible results. The alternative transport needed has not improved enough to encourage drivers to alter their actions and onto public transport. The cost of living taken across different household groups shows that an increase on petrol tax hits the poorest car owner, as well as, rural dwellers (Smith, 2000: 4). These are the people that need a substitute of public transport. Their incomes and budget constraints are the most susceptible to price rises. The governments lack of results in modernizing and producing a good transport alternative are just rationalizations for easy revenue. As with firms supplying homogeneous product we should be aware of the likelihood for them to maximise their profits in the event of a reduction in petrol tax. If the government were to give a 10 percent decrease in fuel tax the firms would not pass on all the savings to the customer. The small differences in price on the petrol forecourt do suggest price fixing, although illegal, it is difficult to prove. The petrol suppliers might, for example, pass on an 8 percent reduction and profit from the other 2 percent. This is a problem in a homogeneous market with few firms, indicative of the markets for natural resources. Although petrol users are also trying to increase their position by fuel tax being reduced. The Government are looking after all interests. These three groups are all willing to maximise their utility. As well as income utility there is utility as a quantitative measure of psychological satisfaction (Etrzioni, Lawrence, 1991: 86) present. The chance of promotion from mak ing more profits, getting something cheaper, or covering short falls in other public services are all difficult to value in financial terms. The inter conflict of interest will not allow for mutually beneficial trade. Rational self-interest depends in which of these groups you are, and to the same extent if you think this is an argument for or against a petrol tax reduction. In conclusion, we have seen that the taxes on petrol are in place to correct externalities by bringing adding social costs to show the real cost of vehicle use. This in turn has shown the petrol market to be one of high taxation with its inelastic nature. The revenue generated would regenerate the public transport sector to allow for alternative travel, although governments have failed to deliver. Tax affects vehicle users who need a substitute for car travel the most. And finally we saw utility maximisation pulling the debate in all directions. Tax reduction maybe a personal issue but there are rational arguments which need addressing to come to a solution in the best interests of society.
