Public Finance and Taxation Essay

There atomic number 18 varying definitions of what reality sector stintings is and what topics it covers. In a laymans terminology Public economicals is the application of economics to the activities undertaken by the stir. Black et al. defines commonplace sector economics as the field of economics which studies the nature, principles, and economic consequences of giving medication expenditure, taxation, financing and the regulatory actions undertaken in the non-profit devising judicature sector. gum olibanum it looks at the capacity of various approaches use by giving medication in its day to day operations. For the government uses economic constitution instruments which be knowing to see economic behavior in tack to gain genuine terminuss. The government has various closings which it pursues they allow i) Macro-economic stabilityii) Enhanced economic increaseiii) Balance of payment stabilityiv) Income distribution.The ultimate aim of these policies is to im prove slews welfargon. As already mentioned government uses instrument of fiscal and monetary policy to action its goal. The use of government expenditure and taxation to influence economic outcome is referred to as fiscal policy. Fiscal policy is a tidy deal outlined through the annual work out which is presented to parliament every year. The budget outlines its objectives in the budget and how these are going to be achieved. On the just about other Monetary policy is aimed at influencing the supply of money and consequently economic growth. The central Bank is an independent arm of the state which is mandated with running the monetary policy. In Zambia, monetary policy is the responsibility of the Bank of Zambia. In gracious beings sector economics we study the impact of instrument of fiscal policy on economic efficiency. Instruments of fiscal policy include i) Expenditureii) tax revenueiii) Financingiv) RegulationsThe first 2 involves the procurement and spending of the government property on various programs such as mankind infrastructure, education, health and public security. voice the government collects revenue using tax and spends the revenue on education, health, roads etc. in economic terms the use of these two constitutes the direct mobilization and tryst of scarce resources. In contrast, regulation entails a law or administratively proclaiming an enforceable instruction that be givens to a divergent parceling of private sector resources than would apply in the absence of government intervention. That is tryst resources are influenced indirectly. Example the government through the Environmental Council of Zambia has present regulations to curb environmental damage this has lead to increased investment in environmentally friendly engineering science by private firms. This is something the profit desire private sector would non know done if in that location was no government intervention. PUBLIC FINANCE AND IDEOLOGYOpinion s on how government should amour in the economic sphere are influenced by the ideological suck ins concerning the kinship between the state and the individual. Political philosophers have distinguished two major approaches. These approaches are the organic encounter and the mechanistic view of government. Organic moot of giving medicationIn this view guild is considered as a native organism and the government is the heart of such an organism. Society is an organic whole, meet as the human body. to sepa countly one individual is a constituent incisionitioning of the organism just like a body part. In this view an individual has significance and as a part of the companionship and the darling of the individual is defined with respect the intelligent of the whole. A persons action is seen as important if it leads to the improvement of the wellbeing of connection. In Platos view, an activity of citizen is only desirable if it leads to a just social club. In this view , the goals of corporation are set by the state which attempts to lead society, toward their realization. The goals of society do differ from one state to a nonher. For example Plato conceived that the goal of government was the achievement of a golden age in which human activities would be guided byrationality. In short society strived to achieve a state in which the decisions of all individuals and the state were rational. So society was view as all activities which would lead to the achievement of this goal. In Adolf Hitlers view, the states goal was the achievement of social purity. He envisaged the creation of a supper race. To achieve this goal the state stand uped all activities which were aimed removing human impurities. They include bizarre actions such as extermination of Jews, physically disabled citizenry and invasion of all countries to ensure that his goals are achieved over the world. The Grand Ayatollah Khomeini argued that the goal of society is to create good call uprs. Thus all actions of individuals and the state should be aimed at creating a cadre of believers. Closer home, Kaunda envisaged that the goal of society was the learning of a just society. He coined the concept of human centered tuition or Humanism. In this ideology he argued all the actions of individuals and government should be aimed achieving a society in which all persons are equal to to to each one one other. Proponents of the organic view argue that indisputable goals are natural for the social organism such as pursuit of sovereignty over some geographical area. From a policy perspective, the organic view emphasizes combating poverty and legality issues notably redistribution of income as justification for government intervention. In addition, this view tends to support existence of a large government. That is government has a large part to play in of the nations activities. Mechanistic View of GovernmentIn this view government is not an organistic part of soc iety, but it is a creation of throng to better achieve their individual goals. Here government is seen as a reflection of individual preferences or tastes. In short, society is a mirror of individual wants and needs. In this case, government intervention is only justifiable if it leads to individual welfare maximization. An individual lead only support a government if it helps him/her to achieve their individual goals. Example government should nurture individuals from violence. To do so the individuals gives government coercive power. In Adam metalworker view, Government should protect society from violence and invasion from other states. This view advocates for government intervention only to correct foodstuff failures and letting the commercialize decide who gets what. In addition, the role of government should be limited tocertain public works such as roads, bridges, sewer, and airports. These are infrastructures which make society crop.There are several divergent views wi thin the mechanistic view. about of these are i) Libertarians View which argue against any(prenominal) further role in the economy beyond providing justice and protecting individual liberty. ii) Social democrats believe that sustained government intervention is need for the good of individuals. These interventions can be as diverse as safety regulations at work place, inhibition racial discrimination, welfare payments to the poor.In totality, the mechanistic approach focuses relatively more than on the efficiency of markets and economic growth.ROLE OF THE STATE1. Equity and cleverness PrinciplesPareto Efficiency-occurs when it is not possible to improve the welfare of some people without devising the welfare anyone worsened.An economic system that is not Pareto efficient implies that it is possible to careen resource allocation without making any one worse saturnine. Example if an economic system is not Pareto Optimal it is possible to increase utilization by one group and reduce for others without making them feel worse off. This is known as Pareto Improvement.Pareto improvement occurs when a change to a distinguishable allocation makes at least one individual better off without making any individual worse off. To make us under this lets assume that i) There are two individuals A and B,ii) There are two goods X and Y,iii) There are two factors of production labour (L) and Capital (K) iv) We assume that we have a static economy such that XA+XB=X and YA+YB=YExchange Efficiency or efficiency in consumptionEfficiency in consumption is achieved when the marginal order ofsubstitution are equal for all personsMRSXYA=MRSXYBThe Marginal tramp of substitute is simply the slope of indifference wind.YXXMRS=-YXIf you have a utility function uX,Y=U0 totally differentiating MUxdX+MUydY=0MRSxy=-dYdX=MUxMUyIn the Edgeworth box efficiency is achieved where the indifference curves are tangentLets fleece a spirit take aim such as e. At steer e it is possible to make person A better without making person B worse off. This can be done by moving along Indifference Curve no B2 to point d. At pointd the welfare of person A improves because he turn tails from a lower indifference curve A2 to a higher indifference curve A3. The improvement for person A continues until point c where the indifference curves are equal. At point c it is not possible to make any Pareto improvement. At point e we have MRSXYAMRSXYBThis also true for point d.This outcome of Pareto efficiency is only possible under completed competition. This is because in perfect competition all consumers face the comparable market prices for these goods. That is they twin the marginal rate of substitution to the same price ratio. MRSXYA=MRSXYB=PxPyEach individual maximizes their utility function subject to the budget constraint. That they maximize the following function U0=uX,Y subject to I=XPx+YPy and and then the langrangian L=UX,Y+(I-XPx-YPy)First order conditionsLX=MUx-Px=0 a nd LY=MUY-PY=0MUX=Px and MUy=Py solving simultaneously we getMUxMUy=PxPy=-dYdX=MRS Therefore, each person will equate their MRS to the price ratio. Production EfficiencyProduction efficiency requires that the marginal order of technical substitution are equal in the production of good X and good Y. That isMRTSLKX=MRTSLKYIn the Edgeworth box this requires this occurs where the isoquants are tangent to each other. The marginal rate of technical substitution is simply the slope of the isoquant. KLU0KGiven an isoquant QL,K=Q0 totally differntiating we get MPldL+MPKdK=0MRTSLK=-dKdL=MPlMPKLets have a factor Edge worth box to make our interpreter easier. Remember from our study of micro-economics we defined an isoquant as a curve that make up the combination of labor and capital which give the same level of siding. In the diagram below production of X uses labor from point X to the right and capital from X upwards. For good Y it is the opposite of good X.All points along XPY are Pareto efficient in the feel that it is not possible to improve or increase the output of good X or good Y without reducing either of them. To under this lets scatter point a which is not along XPY. This point is not Pareto optimal because it is possible to improve the production of X without reducing the output of good Y simply by moving along the isoquant no Y2 output of good X improves/increases to X2 from X1. Pareto efficiency is only possible under a perfectly competitive market system because all produces face the same factor prices (PK and PL). Thus Pareto Optimality condition reduces to MRTSLKX=MRTSLKY=PKPLProofQ0=QL,K subject to C=LPl+YPytherefore the langrangian L=QL,K+(C-LPl-KPk)First order conditionsLL=MPl-Pl=0 and LK=MPk-Pk=0MPl=Pl and MPK=PK solving simultaneously we getMPlMPk=PlPk=-dLdK=MRTS Therefore all firms will be minimizing their costs while facing the same factor prices. boilers suit EFFICIENCYThis requires that the production possibility frontier (PPF) and the social welfare function are tangent. That is MRSXY=MRTXY. XSWFPPFYThe PPF shows the maximum quantity of good X and good Y that can be produced using the existing technology and resources. An increase in the amount of labor and capital available or an increase in the level of technology will make the PPF to move outwards to the right. All points inside the PFF are attainable but not efficient and all points the right of the PPF are not attainable. To achieve, the Marginal Rate of Substitution for society (slope of SWF) must be equal to the PxPy and the marginal rate of transformation (slope of PPF) must be equal to the MCxMCy or resources must be fully utilized. In perfect competition, P=MC. Hence it is possible to achieve the following outcome MRSXY=PxPy=MRTXY=MCXMCY. Thus a perfectly competitive outcome results into a Pareto optimal allocation of resources. It is important to note that Pareto optimal allocation may not be the best outcome in the sense that it does not consider equi ty. That is there is no equity consideration. Equity is the seemly distribution of resources in sources. There are two concepts of equity used in economics horizontal and Vertical Equity. Horizontal equity inwardness that people in similar positions/situation must be interact equally. Example if two people have HIV and the same level of CD4 count they should have equal access to ARVs. The only condition is that they are positive and have the same CD4. Vertical equity means that people in different economic situations must be treated otherwise from a poor person when allocating resources. This is because treating them in the same manner is not equitable. MARKET FAILUREA market failure occurs when the market fails to portion out resources according the Pareto criterion. In other words, a market failure is a situation in which the market fails to allocate resources efficiently according to the Pareto Criterion. primal Theorem of Welfare EconomicsWelfare economics is the systemati c method of evaluating the economic implications of alternative resource allocation. It answers the following questions i) Is a given resource allocation efficient?ii) Who wins and looses under various allocations?First inherent Theorem of welfare Economics- It states that if there is a perfectly competitive market and consumer tastes are convex then any equilibrium will be a Pareto optimal allocation of resources. In short, the competitive market allocates resources efficiently without any need for government intervention. Further, the theorem states that the price from the perfectly competitive market induces selfish individuals independently maximize their welfare, to bring the economy to a socially optimal state. That is prices rise in response to free demand and they fall in response to excess supply. Normatively this theorem says that use free market system to allocate resources. The Second Fundamental Theorem of Welfare Economics states that society can attain any Pareto o ptimal allocation of resources by making a suitable assignment of sign endowment of resources and then letting the people freely trade with each other as in the Edgeworth box. To help us understand this lets relook at the contract curve which gives the Pareto Optimal outcomes.
