risk based analysis and policy implications for renewable energy investments in greece significant renewable energy re investments have to be implemented in order to achieve the ambitious re targets set in the eu for 2020 and beyond moreover a great amount of capital has to be leveraged as these projects are followed by high investment and financing costs main aim of this paper is the provision of a comprehensive assessment of the existing risk elements of re investments in relation to the respective policies and the evaluation of their impact on the weighted average cost of capital wacc in greece a consultation procedure with key national energy stakeholders took also place including policy makers project developers investors equity providers bankers and energy analysts in the greek re market in order to provide a validation of the respective results it has been concluded that the policy design risk represents the risk element with the greatest impact on the cost of capital and thus the level of re investments deployment ased on the cost of capital valuation process followed the wacc was estimated to reach approximately 12 for onshore wind and little lower values for solar pv projects in greece

externality and literacy a note abstract kaushik basu and james foster 1998 have opened up an interesting approach to the measurement of literacy in which the phenomenon of externality has an important role to play the externality these authors examine is what one may call a material externality and they demonstrate that reckoning such an externality in the measurement of literacy provides an instrumental justification for horizontal equity the present note elucidates this link through a specific formulation of the basu foster thesis it also suggests that apart from a material externality there is also a psychic externality to be considered the psychic externality runs in a direction somewhat orthogonal to that of the material externality postulated by basu and foster and it is shown that reckoning such an externality in the measurement of literacy provides an instrumental justification for being sensitive to levels of literacy attainment in comparisons of literacy improvements in a broad sense the note suggests

measurement of welfare applications to australia abstract this paper is concerned with the measurement of welfare which takes into account both the size and distribution of income an alternative approach to measuring welfare which captures the sense of envy felt by individuals when they compare their incomes with each other is considered this methodology is then used to analyse the extent and nature of welfare in australia the main objective of the empirical investigation is to measure the direct impact of australian personal taxes and government cash transfers on the distribution of economic welfare by the size of income and by other household characteristics the household expenditure survey 1975 1976 forms the basis of the present study

optimizing the level of renewable electric r d expenditures using real options analysis abstract one of the primary objectives of the united states federal non hydro renewable electric r d program is to promote the development of technologies that have the potential to provide consumers with stable and secure energy supplies in order to quantify the benefits provided by continued federal renewable electric r d this paper uses real option pricing techniques to estimate the value of renewable electric technologies in the face of uncertain fossil fuel prices within the real options analysis framework the current value of expected future supply from renewable electric technologies net of federal r d expenditures is estimated to be 30 6 billion of this value 86 can be attributed to past federal r d efforts and 14 can be attributed to future federal r d efforts assuming continued federal r d funding at 300 million yr in addition real options analysis shows that the value of renewable electric technologies increases as current and future r d funding levels increase this indicates that the current level of federal renewable electric r d funding is sub optimal

comment on the relative deprivation curve and its applications the article by kakwani 1984 introduced a measure of inequality that is weighted to take account of a sense of deprivation an individual may feel on seeing others who are better off in the second part of the article kakwani presented estimates of deprivation using australian data i would like first to comment on the welfare implications of the measure of relative deprivation proposed in the article and second to point out some crucial assumptions underlying the use of household incomes in the empirical work the measure of relative deprivation is based on a utility function for the representative individual of the form w u y x with uy x uy 0 for y o where x is own income and y denotes the incomes of other individuals the condition uy x is interpreted as the deprivation an individual suffers with an increment in the income of any individual who is better off the conditions on uy introduce a crucial asymmetry in the individual s utility function the individual suffers deprivation on observing incomes above x but derives no sense of satisfaction from observing individuals on incomes below x under this condition a social welfare function of the form w u w u o does not necessarily satisfy the pareto criterion it may be possible to increase social welfare by making some people worse off without making anyone better off in particular it may be possible to increase social welfare by reducing incomes of individuals just above x who may be relatively poor if x is sufficiently low clearly this is the case when the utility function is specified as

multivariate measures of well being and an analysis of inequality in the michigan data we demonstrate a multidimensional approach for combining several indicators of well being including the traditional money income indicators this methodology avoids the difficult and much criticized task of computing imputed incomes for such indicators as net worth and schooling inequality in the proposed composite measures is computed using relative inequality indexes that permit simple analysis of both the contribution of each welfare indicator and its factor components and within and between components of total inequality when the population is grouped by income levels age gender or any other criteria the analysis is performed on u s data using the michigan survey of income dynamics

working life well being and welfare reform motivation and institutions revisited summary this article revisits the relation between economic institutions and motives to work it proposes moving away from a dominant polemical focus on the impact of a single source of security income support towards a multi factorial analysis based on control over working life as a source of well being and motivation to work drawing on surveys of two urban constituencies in sao paulo brazil it is found that income security supports an aristotelian principle of work motivation as individual development however labour market institutions and opportunity levels affect this link implications include a need to consider the distribution of economic control as a key aspect of both human and economic development

stature and the standard of living research on the standard of living now emphasizes alternatives or supplements to the national income accounts this paper reviews the results of two decades of research using stature as a measure of health aspects of human welfare after comparing and contrasting stature with per capita income i consider height patterns discovered by economic historians that challenge traditional beliefs about the past including long term trends cycles in heights and the dreadfully small stature of slave children that was followed by catch up growth the paper concludes with comparisons to work in development economics and suggestions for research

return on capital of brazilian electricity distributors a comparative analysis abstract this paper analyzes the electricity distribution segment in brazil from 1998 to 2005 after the conclusion of privatization process trying to assess whether the return on capital invested was in line with the risk required in the segment it concludes that the return on equity in brazil was systematically negative until 2003 only in 2005 did the distribution segment really begin to recover showing profitability consistent with the estimated cost of equity comparisons with argentine chilean and american companies reveal that firms in the latter two countries generally managed to reward shareholders according to the opportunity cost of capital estimates are that to sustain annual growth of roughly 3 7 for the next decade the entire electricity sector will demand us 7 billion in capital expenditures a year for the next decade 67 for generation 16 for transmission and 17 for distribution in order to stimulate private capital investment it is fundamental for the regulator in the tariff revision processes to consistently assure a rate of return on capital in line with the segment s real opportunity cost and therefore maintain the health of all the three segments without the burden of subsidies

integrating financial theory and methods in electricity resource planning decision makers throughout the world are introducing risk and market forces in the electric power industry to lower costs and improve services incentive based regulation ibr which replaces cost of service ratemaking with an approach that divorces costs from revenues exposes the utility to the risk of profits or losses depending on their performance regulators also are allowing for competition within the industry most notably in the wholesale market and possibly in the retail market two financial approaches that incorporate risk in resource planning are evaluated risk adjusted discount rates radr and options theory ot these two complementary approaches are an improvement over the standard present value revenue requirement pvrr however each method has some important limitations by correctly using radr and ot and understanding their limitations decision makers can improve their ability to value risk properly in power plant projects and integrated resource plans

capability failure and group disparities some evidence from india for the 1980s this paper advances a particular measure of deprivation called the capability failure ratio cfr on the dimensions of longevity knowledge and income and suggests how an inequality adjusted version of the cfr may be derived these measurement concerns are explored in the context of relevant state wise data for the indian union the paper thus makes an attempt to enrich the analysis of human predicament by sensitising measures of central tendency to distributional concerns

large cash transfers to the elderly in south africa we examine the social pension in south africa where large cash sums about twice the median per capita income of african households are paid to people qualified by age but irrespective of previous contributions we present the history of the scheme and use a 1993 nationally representative survey to investigate the redistributive consequences of the transfers documenting who receive the pensions their levels of living and those of their families we also look at behavioural effects particularly the effects of the cash receipts on the allocation of income to food schooling transfers and savings in south africa a large social pension about twice the median per capita income of african households is paid in cash to people qualified by age irrespective of previous contributions we present the history of the scheme and explain how such large transfers could come about in an economy in which the recipients were not only politically weak but without any political representation whatsoever we then use a 1993 nationally representative survey to investigate the redistributive consequences of the transfers documenting who receive the pensions their levels of living and those of their families we also look at behavioural effects particularly the effects of the cash receipts on the allocation of income to food schooling transfers and savings the pressing policy issue for south africans is whether it makes sense to target seven billion rand nearly 2 billion of social expenditure through the current pension schemes our analysis contributes to the discussion by documenting the redistributive and behavioural effects of the transfers we find that at least as far as immediate incidence is concerned and without allowance for behavioural effects the social pension is an effective tool of redistribution and that the households it reaches are predominantly poor because so many of the elderly among south africa s african population live with children the social pension is also effective in putting money into house

solar feed in tariffs in a post grid parity world the role of risk investor diversity and business models over the past decade feed in tariffs have spurred significant deployment of solar photovoltaics in germany and other countries with recent cost trends several countries are approaching retail grid parity some policymakers conclude that now is the time to remove feed in tariffs as grid parity creates a self sustaining market where economically rational investors will invest even in the absence of government incentives recent experience in key european solar markets however shows that with the advent of grid parity and the reduction of feed in tariffs investment in new solar capacity has decreased rather than increased making it questionable whether low carbon energy policy targets will be reached we conduct a cross case study analysis of three pv markets germany italy and switzerland to investigate the role of feed in tariffs for the near and post grid parity stages of diffusion accounting for investor diversity and distinguishing between implications for revenue based and savings based business models we find that recent market trends are strongly driven by increased levels of risk especially policy risk and exposure to revenue risk we therefore suggest that relatively frugal but stable policy environments may be conducive to further growth of investment in photovoltaics and minimize cost to society

growth rates of per capita income and aggregate welfare an international comparison this paper is concerned with the measurement of aggregate growth rates where the aggregation is over time the paper demonstrates that any mechanical procedures for computing aggregate growth rate

deprivation and social exclusion social exclusion manifests itself in the persistent relative lack of an individual s access to functionings compared with other members of society and we model it as being in a state of deprivation over time we view deprivation as having two basic determinants the lack of identification with other members of society and the aggregate alienation experienced by an agent with respect to those having fewer functioning failures using an axiomatic approach we characterize new individual and aggregate measures of deprivation and social exclusion the aggregate measures are then applied to eu data for the period 1994 2001

targeting the poor in mexico an evaluation of the selection of households into progresa abstract in this paper we conduct an evaluation of the targeting method used by health education and nutrition program progresa of mexico to identify beneficiary households we address two key questions a how well does progresa s targeting perform and b how does the program perform in terms of its impact on poverty alleviation relative to other feasible methods and transfer schemes the first question is accomplished by comparing progresa s method to an alternative selection method based on household consumption which is our preferred measure of welfare we employ the concepts of undercoverage and leakage and find that progresa selection method is more effective in identifying the extremely poor localities or households but less so when it comes to distinguishing among localities or households in the middle of the scale to address the second question we compare the potential impact of progresa on poverty alleviation against uniform transfers that involve no targeting at all targeting based on consumption and geographic targeting i e targeting at the locality level rather than at the household level we find that progresa s method of targeting households outperforms uniform coverage and targeting at the locality level in terms of reducing the poverty gap and severity of poverty indices even after taking into account the economic costs of targeting but the closeness of progresa s performance to what could be achieved by geographic targeting alone raises some serious questions about the costs and benefits associated with the practice of household targeting within poor localities

inference tests for gini based tax progressivity indexes distribution free statistical inference procedures for changes in lorenz and gini based indexes of tax progressivity are developed and applied related but distinct tests for the reynolds smolensky index of residual progression and the kakwani index of liability progression are provided the inference procedures are illustrated by applying them to luxembourg income study microdata for sweden the united kingdom and the united states before and after periods of tax reform in each country a finding of significant change depends on the choice among progressivity indexes no single index exhibits a consistent pattern of significant change in all countries across time

electricity markets volatility estimates regularities and risk management applications the recent deregulation of the market for electric power in many parts of the us and canada has expanded the set of potential tools for managing the types of risks faced by both generators and consumers of electric power in particular manufacturing and other firms whose operations are powered by electricity now face on a continuing basis the engineering management decisions concerning whether they should buy or produce electricity and if they are to buy or sell electricity what types of contracts are optimum these types of risk management decisions typically involve futures forwards options and other financial derivatives the price and volatility of electric power are known to play an essential role in determining which of these instruments should be used however electricity as a commodity possesses certain special features not shared by other commodities and hence its risk properties are not yet well understood in this paper we consider and test certain hypotheses about the properties of electricity price using recent market data we find that electricity prices possess certain volatility and other systematic properties that can be characterized by the type and method of delivery of electricity these properties can be used by firms in formulating their optimal demand and supply schedules of electric power

the gini coefficient majority voting and social welfare majority voting and social evaluation functions are the main alternatives proposed in the literature for aggregating individual preferences despite these being very different this paper shows that the ranking of income distributions symmetric under the same transformation by s gini consistent social evaluation functions and majority voting coincide if and only if the inequality index under consideration is the gini coefficient in this case we show that the equally distributed equivalent income is equal to the median of the distribution in addition we find that the gini coefficient is just an affine function of the median mean ratio

melioration a theory of distributed choice in this paper we develop a theory of individual choice called melioration which implies that choices distributed over a period of time may be reliably and predictably suboptimal in terms of the person s own preferences consider some typical examples of distributed choices the expenditure rate on various non durables frequency of athletic exercise rate of work in free lance type occupations allocation of leisure time rate of savings or dissavings expenditures on lottery tickets and other forms of gambling when people express dissatisfaction about their choices their discontent seems clustered around these sorts of distributed choices for example complaints that one is working too hard or not hard enough exercising too little or too much wasting time overeating overspending and so on are commonplace the next two sections of the paper spell out the basic theory we are proposing the following section then applies the theory to pathological consumption patterns and shows that one should find a general underinvestment in those activities that exhibit increasing average returns to rate of consumption and an overinvestment in activities that have an addiction like interaction between value and rate the final section compares the theory with other approaches to suboptimal choice

proximity sensitive individual deprivation measures we characterize a generalization of the linear index of individual deprivation our class allows for an income increase of a higher income individual to have a stronger impact the closer they occur to the income of the person under consideration

implications of applying solar industry best practice resource estimation on project financing abstract solar resource estimation risk is one of the main solar pv project risks that influences lender s decision in providing financing and in determining the cost of capital more recently a number of measures have emerged to mitigate this risk the study focuses on solar industry s best practice energy resource estimation and assesses its financing implications to the 27 mwp solar pv project study in brunei darussalam the best practice in resource estimation uses multiple data sources through the measure correlate predict mcp technique as compared with the standard practice that rely solely on modelled data source the best practice case generates resource data with lower uncertainty and yields superior high confidence energy production estimate than the standard practice case using project financial parameters in brunei darussalam for project financing and adopting the international debt service coverage ratio dscr benchmark rates the best practice case yields dscrs that surpass the target rates while those of standard practice case stay below the reference rates the best practice case could also accommodate higher debt share and have lower levelized cost of electricity lcoe while the standard practice case would require a lower debt share but having a higher lcoe

welfare measures an international comparison abstract based on previous work by sen and the author alternative welfare measures are proposed that take into account both the level and distribution of income an empirical application shows that there are substantial differences among countries with respect to the level of welfare even among subgroups such as mature capitalist economies

the impact of globalization on the poor in latin america this paper consists of four parts following an introduction section 2 analyzes and describes the main channels transmission mechanisms through which the process of globalization affects poverty directly and indirectly section 3 reviews the major effects of globalization on the latin american economy keeping in mind that few generalizations can be made with much assurance section 4 focuses on 13 case studies of the impact of globalization within different latin american settings undertaken under the auspices of a unu wider project directed by the authors these case studies reveal clearly how the effects of different manifestations of globalization on poverty tend to be context specific in general the main globalization channels appeared not to have been able to reduce overall poverty in the region between 1981 and 2004 growth was anemic and its pattern was not pro poor instead bringing about greater income inequality the transfer of technology tended to benefit the skilled workers and hurt the unskilled the one ray of hope in an otherwise bleak picture consists of the safety nets and social protection schemes implemented in an innovative fashion by some of the larger countries in the region

scaling up finance for off grid renewable energy the role of aggregation and spatial diversification in derisking investments in mini grids for rural electrification in india abstract today about 1 1 billion people lack access to electricity worldwide it is estimated that annual investments of 48 billion usd are required to meet the target of the sustainable development goals of providing universal electricity access by 2030 the need for private investments to meet this target is evident but small scale electrification projects are often unattractive for private investors due to unfavourable risk return profiles and small investment volumes both issues can potentially be addressed by aggregating projects into diversified portfolios an approach commonly used by investors in several contexts but little investigated in the context of rural electrification this paper addresses the question of how spatial diversity in a portfolio can be used to reduce investment risks and increase investment volumes through a mixed method approach involving three steps i identification and classification of investment risks for renewable energy mini grid projects ii qualitative analysis of the correlations between investment risks for different projects through interviews and iii quantitative estimation of the cost of capital and derisking effects of spatial diversification strategies for an experimental portfolio in india we discuss the implications for policymakers in promoting and facilitating the ability of private sector investors to aggregate small scale electrification investments

revisiting the techno economic analysis process for building mounted grid connected solar photovoltaic systems part two application part one in this two part paper identified monte carlo analysis as an improved approach over traditional deterministic techno economic methods for solar pv prosumers in deregulated markets in this

the possibility of social choice the subject of social choice includes within its capacious frame various problems with the common feature of relating social judgments and group decisions to the views and interests of the individuals who make up the society or the group some challenges and foundational problems faced by social choice theory as a discipline are discussed social choice theory is a subject in which formal and mathematical techniques have been very extensively used voting based procedures are entirely natural for some kinds of social choice problems such as elections referendums or committee decisions they are however altogether unsuitable for many other problems of social choice impossibility results in social choice theory led by the pioneering work of arrow 1951 have often been interpreted as being thoroughly destructive of the possibility of reasoned and democratic social choice including welfare economics that view is argued against

quantifying the impact of r d on pv project financing costs abstract energy technology research and development r d typically focuses on advancing the performance and reducing equipment and installation costs however such r d can also have significant indirect impacts on other factors incorporating the impact that r d activities have on financing costs can provide a more complete picture of the consequences of these decisions and may allow policymakers to make better decisions in this paper we discuss some historical examples of r d impacting financing costs in the solar energy sector summarize the areas of r d that can impact financing and describe methodological approaches that can be used to quantify the impact of r d on financing costs and as a result the levelized cost of energy lcoe we estimate that r d driven reductions in financing costs in the solar sector from current levels to low risk levels could reduce lcoe approximately 25 alternatively without the r d advances needed to prevent future risks and complications financing costs in the solar sector could increase by as much as 115

evaluating the causes of cost reduction in photovoltaic modules abstract photovoltaic pv module costs have declined rapidly over forty years but the reasons remain elusive here we advance a conceptual framework and quantitative method for quantifying the causes of cost changes in a technology and apply it to pv modules our method begins with a cost model that breaks down cost into variables that changed over time cost change equations are then derived to quantify each variable s contribution we distinguish between changes observed in variables of the cost model which we term low level mechanisms of cost reduction and research and development learning by doing and scale economies which we refer to as high level mechanisms we find that increased module efficiency was the leading low level cause of cost reduction in 1980 2012 contributing almost 25 of the decline government funded and private r d was the most important high level mechanism over this period after 2001 however scale economies became a more significant cause of cost reduction approaching r d in importance policies that stimulate market growth have played a key role in enabling pv s cost reduction through privately funded r d and scale economies and to a lesser extent learning by doing the method presented here can be adapted to retrospectively or prospectively study many technologies and performance metrics besides cost

deconstructing the law of effect abstract do the consequences of past behavior alter future policy as the law of effect assumes or are behavioral policies based on behaviorally produced information about the state of the world but not themselves subject to change in the first case stable policies are equilibria discovered by trial and error so adjustments to abrupt changes in the environment must proceed slowly in the second adjustments can be as abrupt as the environmental changes matching behavior is the robust tendency of subjects to match the relative time and effort they invest in different foraging options to the relative incomes derived from them measurement of the time course of adjustments to step changes in the reward scheduling environment show that adjustments can be as abrupt as the changes that drive them and can occur with the minimum possible latency broader implications for theories about the role of experience in behavior are discussed

linkages between pro poor growth social programmes and labour market the recent brazilian experience summary this paper analyzes the relationship between growth patterns poverty and inequality in brazil during its globalization process focusing on the role played by the labor market and social programs methodologically the paper makes two contributions to the literature one is the proposal of a new measure of pro poor growth which links growth rates in mean income and in income inequality the other contribution is a decomposition methodology that explores linkages between three dimensions growth patterns labor market performances and social policies the proposed methodologies are then applied to the brazilian national household survey covering the period 1995 2004

composite indices of physical quality of life basic needs fulfilment and income a principal component representation abstract in the context of international comparisons the multivariate method of principal components is suggested for computing composite indices of economic development that capture per capita income basic needs fulfilment and other possible indicators of well being the method is conceptually appealing easy to apply and seems promising in several directions two illustrative applications are given one develops a composite index based on the three pqli constituents and per capita gnp for 147 countries in the other a composite index of basic needs fulfilment is first computed for 82 countries and then a more inclusive measure that also takes account of per capita gnp is derived

the inequality adjusted human development index a constructive proposal abstract this paper proposes a method to incorporate a concern for distributional inequalities of income education and longevity into the framework of the human development index hdi as it is presently designed by the united nations development programme the paper constructs gini coefficients for a set of 20 developing countries measuring inequalities in annual income educational attainment and life span attainment these calculations are combined with data from the hdi to produce an inequality adjusted human development index iahdi the implications of this proposed index for evaluating and promoting development are considered

paths to success the relationship between human development and economic growth summary this paper explores the two way relationship between economic growth eg and human development hd we develop panel data strategies to estimate the strength of these relationships and find that hd plays an essential role in determining growth trajectories our measure of sustained growth not only is hd a final product in the sense that it measures basic human well being but it is also a critical input into eg our findings illustrate the empirical relevance of endogenous growth and are consistent with threshold effect models our results imply that successful policy requires an early focus on hd not only because of its direct impact but also because of its feedback effect on sustaining eg

evaluating energy efficiency investments accounting for risk in the discounting process a prominent feature of the literature regarding the economics of energy conservation is the debate over the existence and nature of the so called efficiency gap a frequent subject of debate is whether consumers apply a reasonable discount rate when evaluating the future benefits of energy efficiency measures a key aspect of the discounting debate is the manner in which consumer attitudes toward risk are accounted for when discounting this paper suggests that an appropriate approach to incorporating risk into the evaluation of energy efficiency projects would yield higher net benefits to such projects than standard evaluation techniques we argue that analysing the purchase of fuel saving capital as though it were a standard investment in a physical asset obscures an important feature of the decision rather than deciding whether or not to invest in an asset with an uncertain future benefit stream the consumer is actually choosing between two future cost streams each of which is uncertain this seemingly minor change in perspective has important implications for how the risk associated with fuel saving capital should be brought into the discounting process an example based on lighting technologies is used to illustrate the principles discussed

a real option based simulation model to evaluate investments in pump storage plants investments in pump storage plants are expected to grow especially due to their ability to store an excess of supply from wind power plants in order to evaluate these investments correctly the peculiarities of pump storage plants and the characteristics of liberalized power markets have to be considered the main characteristics of power markets are the strong power price volatility and the occurrence of prices spikes in this article a valuation model is developed capturing these aspects using power price simulation optimization of unit commitment and capital market theory this valuation model is able to value a future price based unit commitment planning that corresponds to future scope of actions also called real options the resulting real option value for the pump storage plant is compared with the traditional net present value approach because this approach is not able to evaluate scope of actions correctly it results in strongly smaller investment values and forces wrong investment decisions

measuring pro poor growth in non income dimensions current concepts and measurement of pro poor growth is entirely focused on the income dimension of well being this neglects non income dimensions of poverty and the multidimensionality of poverty and wellbeing in this paper we introduce the multidimensionality of poverty into the measurement of pro poor growth measurement by applying the growth incidence curve to non income indicators we develop growth incidence curves and calculate the associated ravallion chen pro poor growth measures for a range of non income indicators such as education mortality vaccinations stunting and a multidimensional wellbeing measure and are thereby able to study improvements in these dimensions of well being at various points of the distribution of those indicators as well as at various points of the income distribution this way we can determine whether improvements in non income indicators were pro poor in an absolute or relative sense we illustrate this empirically for bolivia between 1989 and 1998 and find that growth was relatively pro poor in the non income dimension results for absolute improvements are less clear

explaining international and intertemporal variations in income inequality this paper explores the propositions that income inequality is relatively stable within countries and that it varies significantly among countries a new and expanded data set provides broad support for both propositions drawing on a political economy and capital market imperfection arguments to explain the intertemporal and international variation in inequality the empirical analysis shows that the predicted variables associated with the first argument a measure of civil liberties and the initial level of secondary schooling and the second argument a measure of financial depth and the initial distribution of land are indeed important determinants of inequality this paper explores two propositions regarding income inequality they are first income inequality is relatively stable within countries and second it varies significantly across countries to illustrate note that the gini coefficient in india remained almost constant for forty years 1951 92 with mean 32 6 and standard deviation 2 0 2 in contrast the variation in gini coefficients across countries is large 61 9 in honduras in 1968 compared with 17 8 in bulgaria in 1976 if substantiated these propositions have potentially significant implications for poverty the significance of the first is obvious barring any fundamental socio political change poverty reduction will depend crucially on the rate of economic growth given this the significance of the second is that in inegalitarian economies the poor will enjoy a smaller share of any national increment in income than in more egalitarian ones drawing on a new and expanded data set on inequality deininger and squire 1996a the first of the paper s three sections conducts standard statistical tests of the two propositions the sample comprises 573 observations on the most common measure of inequality the gini coefficient for 49 developed and developing countries covering the period 1947 94 the results broadly confirm our two propositions specifically analysis of variance anova shows that about 90 of the total variance in the gini coefficients

the relative deprivation curve and its applications this article introduces the relative deprivation curve to represent the size distribution of income and wealth the curve has many useful applications in the measurement of poverty and inequality which are explored the methodology developed is then applied to the data obtained from the australian household expenditure survey 1975 1976
