pollution without subsidy what is the environmental performance index overlooking abstract agriculture is heavily subsidized in most organization for economic cooperation and development oecd countries and environmental externalities can occur due to pollution caused by protectionist policies this study examines the structure of agricultural protection in oecd countries from a chronological and comparative perspective in addition the policy environment interaction is scrutinized to better explain the environmental implications of agricultural policies in the era of globalization this paper critically evaluates the environmental performance index and recommends that this index includes polluting inputs in future calculations

measuring food security in africa conceptual empirical and policy issues the definition of food security has broadened since the term first came to prominence at the 1975 world food conference discussions of food security in the midand late 1970s were strongly influenced by the shortfall in world food production and run up in prices early in that decade initially food security meant avoiding transitory shortfalls in the aggregate supply of food by the early 1980s however the world food supply situation had evolved markedly the famines striking africa took place in a world awash in grain clearly inadequate levels of global food supply were not the cause of hunger sen s work focused attention on the lack of access by households and individuals to food because of low incomes entitlements as a cause of food insecurity and other research has shown that for most of the hungry in the world this lack of access is chronic not transitory thus the conceptual understanding of food insecurity has gradually evolved over the past fifteen years to include not only transitory problems of inadequate supply at the national level but also chronic problems of inadequate access and unequal distribution at the household level d spite a broader understanding of the complexity of food insecurity policy makers must still look for easily measured indicators to design programs to reach the food insecure often these indicators are measures of regional or national food supply or its correlates such as rainfall as current information on household or individual entitlements to food is usually lacking s me policy makers may think of supply shortfalls or the lack of domestic food self suffi

inequality aversion and the natural rate of subjective inequality abstract this paper analyzes inequality aversion across countries and identifies factors which explain the empirical heterogeneity observed across these countries we do this by hypothesizing a natural rate of subjective inequality across countries and solving for the explicit country specific value of the inequality aversion parameter that is consistent with the hypothesized natural rate we present evidence consistent with the existence of a natural rate of subjective inequality by verifying that countries with low high tolerance for inequality have low high inequality as measured by the gini coefficient as well finally we explore the socio economic factors that are consistent with observed differences in inequality aversion across these countries finding important effects of female empowerment public education expenditures per capita income economic growth and population size

strikes free riders and social customs in recent years there has been a growing literature on the role of social customs in the labour market marsden 1986 for example has emphasised the importance of group norms and social custom in various labour market contexts jones 1984 develops an economic model of conformist behaviour in which an individual s work effort is determined partly by tradition and by the behaviour of other workers a central theme of the literature is that a rational economic agent does not inhabit a social vacuum and hence that individual behaviour is influenced to some extent by the actions of others the approach promises the possibility of an escape from the free riders problem which as we shall investigate might have a number of labour market applications such a potential has been suggested by a number of writers in different fields eiser 1978 writing from a socio psychological perspective has stressed the role of social norms in producing cooperative outcomes in the theoretical context of the prisoner s dilemma such an emphasis is consistent with sen s 1977 argument that the concept of commitment might offer a solution to the free rider problems

on the principle of equal sacrifice in income taxation abstract in an influential article by young journal of economic theory 1988 44 321 335 it is shown that the traditional equal sacrifice principles in taxation can be justified from a non utilitarian perspective by proving that equal sacrifice is in fact a consequence of more primitive concepts of distributive justice this result is obtained in a distribution theoretic setting where total revenue to be raised is fixed the present paper studies the same question in a setting where the basic problem is to determine a tax function without any reference to the total tax revenue a setting which is familiar from the theory of progressive taxation and shows that i there exists a utility function which is continuous and strictly increasing relative to which all agents sacrifice equally if and only if the tax function is incentive preserving and ii any convex hence progressive and incentive preserving tax function equalizes sacrifice relative to a utility function which is continuous strictly increasing and concave

on the equitability of progressive taxation abstract we propose the principle of equal sacrifice to determine the class of vertically inequitable progressive taxes a necessary condition for an income tax function to be equal sacrifice is formulated and hence a subclass of progressive taxes which cannot inflict the same sacrifice upon all individuals relative toanystrictly increasing and concave utility function is determined conversely it is shown in a general framework that any convex thus progressive tax function satisfies the principle of equal sacrifice our findings point to the fact that equal sacrifice under progressive income taxation depends heavily upon the degree of marginal rate as opposed to average rate progressivity journal of economic literatureclassification numbers d63 h20

is trade good or bad for the environment sorting out the causality we seek to contribute to the debate over globalization and the environment by asking what is the effect of trade on a country s environment for a given level of gdp we take specific account of the endogeneity of trade using exogenous geographic determinants of trade as instrumental variables we find that trade tends to reduce three measures of air pollution statistical significance is high for concentrations of so2 moderate for no2 and lacking for particulate matter although results for other environmental measures are not as encouraging there is little evidence that trade has a detrimental effect on the environment

linking namea and input output for consumption vs production perspective analyses evidence on emission efficiency and aggregation biases using the italian and spanish environmental accounts we integrate input output and namea tables for spain and italy in 1995 2000 and 2005 in order to address the hot policy issue of sustainable consumption and production a comparison of production and consumption perspectives may have relevant policy implications we deal with the domestic technology assumption and primarily the aggregation bias that may result when calculating indirect emission using different sector aggregations in the analyses e g 16 30 50 extended input output analysis provides analyses of the emissions embodied in domestic consumption and domestic production by considering the structure of intermediate inputs and environmental efficiency in each production sector our empirical findings show that different sectoral aggregation significantly biases the amount of emissions for the consumption perspective though differently in the two countries italy surprisingly show consumption production ratios around or lower than one but in line with some major work at eu level our results thus suggest that special attention must be paid when interpreting the ee ioa of country estimated amounts of embodied emissions both in domestic final demand and those directly associated with the production sectors when the sectoral aggregation level has a low definition as considered in some recent similar studies

measuring attitudes towards inequality individuals attitudes to inequality aversion are measured using survey data based on the leaky bucket experiment for several groups of students in australia and israel three forms of social welfare function are estimated it is found that measures of inequality aversion can be obtained with some precision and that these estimates are substantially lower than the values typically used by those measuring inequality and examining optimal tax structures furthermore a welfare function based on the gini inequality measure is generally found to give a better fit than forms based on constant relative or constant absolute inequality aversion jel classification c91 d63

food security strategies under extremely adverse conditions the determinants of household income and consumption in rural mozambique abstract this paper uses household survey data from war torn northern mozambique to examine the factors associated with higher incomes and improved rural household food security incomes and calorie consumption were found to be low and variable in each district and both are highly correlated with land holdings the central role of land holdings is largely a result of serious market failure food market participation rates and the proportion of net buyers are lower than in other sub saharan africa ssa research purchased food as a percentage of total caloric intake and off farm income as a percentage of total income are both very low by ssa standards in short surveyed smallholders have adopted a strategy of marked reliance on farm based own production to ensure their survival it is suggested that land holdings will continue to be key determinants of household income and consumption for the foreseeable future broad based rural development efforts possibly organized around existing cotton growing enterprises may offer one way out of the poverty trap for smallholders

a note on the natural rate of subjective inequality hypothesis and the approximate relationship between the gini coefficient and the atkinson index abstract in a recent paper in this journal lambert et al j public econ 87 2003 1061 sought to establish the natural rate of subjective inequality nrsi hypothesis their statistical analysis however may have simply identified a relationship between the gini coefficient and the atkinson index rather than confirm the existence of a nrsi in this note an approximate relationship between the gini coefficient and atkinson index is identified using simulation analysis this finding does not appear to overturn the nrsi hypothesis and indicates the need for further investigation of this insightful and potentially far reaching hypothesis

who wants to redistribute the tunnel effect in 1990s russia abstract support for governmental redistribution tended to be greater for the poor than the rich in a representative sample of russian adults in 1996 however support for redistribution is higher amongst those who expect their welfare to fall and this effect is strongest amongst the currently well off a rising trajectory inhibits demand for redistribution support is also stronger in rural areas amongst those with less schooling those who fear losing their job the elderly and amongst women our results are consistent with albert hirschman s idea of a tunnel effect whereby prospects of mobility in both directions influence demand for governmental redistribution

neoclassical growth the j curve for abatement and the inverted u curve for pollution abstract this paper reexamines the neoclassical environmental growth model of forster to gain insights into the dynamic relationships among pollution abatement effort and economic development whereas the model has heretofore been used to examine steady state levels of capital consumption and environmental quality it also provides a theoretical basis for recent empirical research on j curves for abatement effort and inverted u curves for pollution

unequal societies income distribution and the social contract this paper develops a theory of inequality and the social contract aiming to explain how countries with similar economic and political fundamentals can sustain such different systems of social insurance fiscal redistribution and education finance as those of the united states and western europe with imperfect credit and insurance markets some redistributive policies can improve ex ante welfare and this implies that their political support tends to decrease with inequality conversely with credit constraints lower redistribution translates into more persistent inequality hence the potential for multiple steady states with mutually reinforcing high inequality and low redistribution or vice versa

economic openness and green gdp since the early 1990s there have been several attempts to develop national income accounting systems which recognize the negative impacts of environmental degradation and income inequalities on economic welfare collectively these bgreenq gross domestic product gdp studies have generated a wealth of new time series data sets which can be used to reexamine the links between gdp and a host of factors commonly included in traditional economic growth models in this paper we develop models of green gdp growth and the gap between traditional and green gdp by using a panel data set from eight countries spanning 30 50 years in both the growth and gap models the effects of economic openness are tested we find strong and robust results suggesting a negative nonlinear correlation between openness and green gdp growth and a positive nonlinear correlation between openness and growth of the gap between traditional and green gdp while green gdp accounting systems are still in their infancy our paper nonetheless implies that once these more comprehensive measures are fully developed empirical models which explore factors contributing to the growth of economic welfare over time should be reexamined d 2005 elsevier b v all rights reserved

free trade and the environment development system abstract we develop a simulation model to analyze the trade environment development system that contains a number of important advances over the earlier and current theoretical models our model like other models has an income induced pollution policy allows country factor endowments to influence trade patterns and allows production factors to be mobile intersectorally unlike other theoretical models our model treats pollution stemming from both production and consumption in a way that does justice to empirical observations we model pollution policy explicitly as an abatement investment thus effectively allowing for differences in pollution intensive technology across countries in addition we allow for an internationally traded intermediate good a natural resource as a result of this novel approach we find that 1 the benefits of trade i can be either positive or negative and ii depend on country endowments and 2 the pollution effects of trade are closely tied to the benefits of trade our model generally shows higher pollution levels under free trade than autarky however our results do not support the pollution haven hypothesis i e trade causes less pollution in developed countries and more pollution in developing ones some developing countries produce more of the pollution intensive good but ultimately consume less pollution under autarky because they have higher per capita income and thus invest more heavily in environmental upgrading under autarky

embodied pollution in trade estimating the environmental load displacement of industrialised countries abstract the present paper sets out to aid in the development of environmental load displacement indicators developing the notion of the environmental memory of physical flows we estimated embodied pollution in trade of 18 industrialized countries with a the rest of the world and b developing countries from 1976 to 1994 we found that in the last years of analysis total imports of japan usa and western europe have entailed in general larger air pollutant emissions than local exports the balance of embodied emissions in trade beet seems to follow an inverted u shape across time in japan and western europe and an n shape in the us in the period of analysis japanese and european environmental terms of trade with developing countries improved from the japanese and european point of view whereas american environmental terms of trade with developing countries deteriorated over time although there is no statistical trend between income and embodied emissions in imports in a cross section analysis there does seem to be a positive relationship between both variables at a national level the results suggest that despite many shortcomings this type of assessment may shed useful insights on the international aspects of sustainable development

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource productivity

the interaction of population growth and environmental quality an important question for policy is whether holding constant per capita income and other relevant factors population pressures have a significant effect upon environmental degradation the authors examine the effect of population pressures upon deforestation in 64 developing countries in an attempt to provide relevant empirical findings data on deforestation were drawn from the food and agriculture organizations production yearbook results suggest that a relationship exists between per capita income and deforestation and that for africa rural population density shifts the relationship upward the increase in the rate of deforestation levels off as income increases the rate of growth in per capita income also has a significant negative impact upon deforestation although the magnitude of the effect is small the authors close in stressing that reducing the rate of population growth is not necessarily the best way to reduce the rate of deforestation deforestation in developing countries is really a problem of market failure since property rights are often neither defined nor enforced there is essentially no private cost of deforestation with no long term stake in the land people have no incentive to use land efficiently this situation must be addressed in conjunction with the problems of poverty and population growth

informing food security decisions in africa empirical analysis and policy dialogue discussions of economic and agricultural development in africa have focused heavily in recent years on structural adjustment i e basic policy changes aimed at allowing international and domestic markets to play a greater role in coordinating national economic activities often these structural adjustments and accompanying policies aimed at improving economic performance have been based on several implicit assumptions about how african food systems operate yet for many countries little empirical information has been available to test these assumptions hence designing policies too often becomes an exercise in planning without facts this paper argues that not only is there a need to base food security and structural adjustment policies more firmly on empirical information but that the process by which the information is obtained is as important as the information itself agricultural economists and other social scientists can and increasingly should design policy research in africa in ways that simultaneously increase effective demand for empirical information as an input into the ongoing policy process and augment african capacity continually to inform policy deliberations we illustrate the payoffs to such an approach by drawing on selected experience in several african countries weber

personal income taxation and the principle of equal sacrifice revisited this paper shows that in the domain of piecewise linear statutory income tax functions the principle of equal sacrifice implies tax progressivity the progressivity implication of the doctrine is in fact stronger the equal sacrifice principle in essence characterizes marginal rate progressivity a result which is in sharp contrast with the standard literature on public finance the authors also apply their findings to the personal statutory income taxation practices of the oecd countries and observe that the united states and turkey were the only ones violating the principle of equal sacrifice in the time period 1988 to 1991 copyright 1996 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

are there limits to growth a simple theoretical model of pollution is developed that generates an inverted u shape relationship between per capita income and environmental quality this model is then used to study long run growth the same inverted u shape is shown to appear in time series and the prospects for sustained growth are shown to hinge on whether increasingly strict environmental regulation is compatible with a constant rate of return on capital implementation is also studied tax and voucher schemes are shown to have an advantage over direct regulation because they provide the correct incentives for capital accumulation copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

household food security and nutrition monitoring the malawi approach to development planning and policy interventions abstract this paper documents implementation of food security and nutrition monitoring fsnm at the household level as a process of information generation for food and nutrition planning and policy making a case study of malawi is presented to describe various stages involved in generating data and converting them into policy decisions the institutional arrangement for food security and nutrition monitoring in malawi is presented along with a conceptual framework for identifying factors that influence food security and nutritional status of the population the process of implementing food security and nutrition monitoring in malawi is presented in two parts the process of information generation and the use of results in policy implementation the costs and benefits of food security and nutrition monitoring in malawi are also documented presenting the lessons from the malawi approach the paper concludes that a decentralized system of data collection processing and analysis is more likely to be successful in planning and policy making for food security and nutritional improvements

economic growth trade and energy implications for the environmental kuznets curve abstract the environmental kuznets curve ekc hypothesis asserts that pollution follows an inverted u path with respect to economic growth the ekc has been explained in terms of structural changes in the composition of economic output and increased environmental regulation at higher income levels while some authors have incorporated the impact of trade policy orientation on the ekc the impact of the actual movement between countries of goods that embody pollution has not been considered this paper attempts to econometrically quantify the effect using pooled cross country and time series data the ekc hypothesis is examined with respect to commercial energy consumption the source of many serious environmental problems it was found that while both industrializing and industrialized countries have added to their energy requirements by exporting manufactured goods the growth has been substantially higher in the former at the same time industrialized countries have been able to reduce their energy requirements by importing manufactured goods exports of manufactured goods by industrialized countries has thus been an important factor in generating the upward sloping portion of the ekc and imports by industrialized countries have contributed to the downward slope

trade and the environment a partial synthesis there is an emerging consensus in the environmentalist community opposing free trade while some economists view this as simply another outlet for protectionism recent work has begun to move beyond the rhetoric to probe more deeply into the theoretical and empirical relationships between international trade and environmental quality the purpose of the present paper is twofold we first integrate some of the existing literature by using the simple concepts of general equilibrium pollution supply and demand our survey of the trade and environment literature is more

social mobility and the demand for redistribution the poum hypothesis this paper examines the often stated idea that the poor do not support high levels of redistribution because of the hope that they or their offspring may make it up the income ladder this prospect of upward mobility poum hypothesis is shown to be fully compatible with rational expectations and fundamentally linked to concavity in the mobility process a steady state majority could even be simultaneously poorer than average in terms of current income and richer than average in terms of expected future incomes a e rst empirical assessment suggests on the other hand that in recent u s data the poum effect is probably dominated by the demand for social insurance in the future everyone will be world famous for e fteen minutes andy warhol 1968

bridging the trade environment divide protection for free traders this word represents the consummate evil for environmentalists it is the ultimate good of course for the trade community protection conjures up dark images of smoot and hawley while the environmental camp sees clear mountain streams lush green forests and piercing blue skies one cannot blame all of the tensions at the trade environment interface on linguistic differences but these competing perspectives are emblematic of a deep clash of cultures theories and assumptions trade officials often seek to limit efforts to link trade and environmental policy making and sometimes to prohibit such efforts altogether in this regard the narrow focus and modest efforts of the world trade organization s committee on trade and environment are illustrative 1 the launch of negotiations for a free trade area of the americas with an express decision to exclude environmental issues from the agenda provides an even starker example of the trade community s hostility toward serious environmental engagement economists have been prominent among those arguing that pollution control and natural resource management issues are best kept out of the trade policy making process cooper 1994 bhagwati 1999 other economists however have tried to set trade policy making in a broader context and to build environmental sensitivity into the international trading system runge 1994 rodrik 1997 summers 2000

ranking income distributions using the geometric mean and a related general measure this paper illustrates the usefulness of a generalized welfare measure for ranking income distributions that are unordered by stochastic dominance and illuminates the properties of the measure other welfare criteria such as the arithmetic mean and rawls criteria are special cases of this generalized measure this generalized welfare measure illustrates that use of these special cases involves a subjective judgment by the observer of the relative importance of equity preference to efficiency preference

the environmental consequences of trade evidence from subnational trade flows abstract the debate over the environmental consequences of free trade is not only quite heated but also entails significant policy ramifications recently cross sectional analysis at the country level has made use of exogenous determinants of trade to identify the causal effect of trade on the environment finding moderate evidence of a beneficial impact of expanded trade on environmental quality given the stakes involved we revisit this finding using subnational data on trade flows across us states and several measures of pollution not only does the analysis shed further light on the debate at the international level but also addresses a heretofore unexamined question does greater inter regional commerce at the subnational level harm the environment our findings are striking providing further evidence against a negative environmental impact of trade for the majority of measures analyzed however several sources of heterogeneity arise that are noteworthy

the impact of group based credit programs on poor households in bangladesh does the gender of participants matter this paper estimates the impact of participation by gender in the grameen bank and two other group based micro credit programs in bangladesh on labor supply schooling household expenditure and assets the empirical method uses a quasi experimental survey design to correct for the bias from unobserved individual and village level heterogeneity we find that program credit has a larger effect on the behavior of poor households in bangladesh when women are the program participants for example annual household consumption expenditure increases 18 taka for every 100 additional taka borrowed by women from these credit programs compared with 11 taka for men

political sources of growth a critical note on measurement this note critically reviews the research on the link between political systems and economic growth empirical attempts to capture this patent relationship have been met with mixed success we conclude that the political variables used in these studies i e democracy and political instability do not adequately reflect the investors problem we suggest that a political variable that encompasses all kinds of potential discretionary state interventions would be more effective in explaining cross country differences in economic growth

exploring the relationship between energy usage segregation and environmental degradation in n 11 countries numerous studies regarding the economic growth environmental pollution link have struggled to determine the effects of various forms of energy consumption on environmental degradation particularly in the context of emerging economies this study examines the environmental kuznets curve ekc for co2 emissions in n 11 countries during 1990 2014 by segregating three forms of energy consumption renewable biomass and non renewable urbanization and trade openness are additional explanatory variables that are used in the empirical framework using the generalized moments method gmm the empirical evidence confirms the presence of an n shaped relationship between economic growth and environmental degradation for n 11 countries this study analyzed the interaction effects among trade openness biomass consumption and economic growth these interactions had a negative impact on co2 emissions levels of n 11 countries suitable policy recommendations have been provided based on the detailed results

why poor countries rely mostly on redistribution in kind abstract we present a model in which the crucial distinction between rich and poor countries is that governments in rich countries have access to a more productive tax collection technology than governments in poor countries since the tax collection technology in poor countries is poor the quality of the public service is low therefore many households at the top of the income distribution opt out of the public service the median voter takes this into consideration and allocates a larger share of the public budget to redistribution in kind public service than to redistribution in cash

does trade liberalization harm the environment a new test recent events such as the nafta and the completion of the uruguay round have raised concern over the impact of trade liberalization on the environment in particular it is believed that less stringent environmental standards in developing countries will give them a comparative advantage in pollutionintensive goods using single equation models existing empirical studies have found either no relationship between environment and trade flows or a positive relationship between trade liberalization and the environment this paper develops a simultaneous equations model to estimate this relationship directly incorporating the effects of openness on growth of income and of income growth on environmental damage a two good trade model with endogenous factor supply is estimated using pooled provincial data on chinese water pollution from 1987 1995 estimation of this model reveals that trade liberalization directly aggravates environmental damage via its influence on the terms of trade but indirectly mitigates it via its effect on income growth simulations suggest that trade reform during the period may have had a net beneficial impact on emissions growth

pollution havens and the trade in toxic chemicals evidence from u s trade flows national registries of toxic chemical emissions and facilities are increasingly used to raise public awareness of potential health hazards in local areas but an unintended consequence may be the offshoring of production to less regulated countries using disaggregated u s trade data this study examines the impact of registry listing on subsequent bilateral trade flows estimates from a difference in differences model indicate a significant shift toward imports from poorer countries following registry listing assuming that environmental protection is a normal good this result suggests the emergence of pollution havens due to more stringent u s environmental regulation

how does environmental regulation affect production location of non carbon ecological footprint abstract the aim of the paper is to investigate how the location of non carbon ecological footprint home or abroad changes along with environmental regulation ecological footprint measures the amount of biocapacity required to sustain the consumption patterns of human beings employing panel data analysis the relationship between income and footprints that result from domestic production and importsis investigated for 87 countries during the period 2004 2010 within the environmental kuznets curve ekc framework we find that an ekc relationship cannot be validated for income gdp per capita and non carbon footprints of production and of imports besides the analysis shows that countries reach the turning points for import footprint at lower levels of income once stringency of environmental regulation and enforcement of environmental regulation are accounted for environmental regulations push the economic structure towards a cleaner transformation by which resources can be exploited more effectively and short run losses in economic growth can be avoided in the medium and long run conditional on a successful transformation toward higher value added and cleaner production processes

market opportunities genetic endowments and intrafamily resource distribution child survival in rural india the authors examine how intrafamily resource allocations respond to changes in economic conditions and to genetic differences in children by estimating the determinants of variations in the sex specific survival differentials of rural indian children based on standard census and household survey data they explore in particular the hypothesis that such differences are related to the relative returns to survival with households selectively allocating resources to children in response to variation in sex differences in their expected earnings opportunities as adults data are from the 1961 census and a 1971 household survey excerpt

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

growth learning and redistributive policies abstract this paper develops an endogenous growth model with redistributive taxation in which the growth rate of the economy affects the agents preferences over redistributive policies and therefore the equilibrium level of taxation the main mechanism through which the growth rate affects policy preferences is by changing the ability of the agents to learn their positions in the future distribution of incomes the main result of the paper is that during periods of growth the society opts for less taxation and less redistribution the model also predicts that growing economies are characterized by higher inequality in the distribution of income and by greater mobility of agents within income classes over time

political variables in cross country growth analysis the recent boom in cross country growth analysis has renewed the empirical interest in political sources of economic growth a large number of studies have tested political variables in growth regressions and a very heterogenous set of variables has been proposed to measure economically relevant differences in the political systems of countries this paper distinguishes five categories of relevant political variables democracy government stability political violence policy volatility and subjective perception of politics for each of these categories the specification testing method and results of the most relevant studies are presented and are critically discussed the paper concludes that measures of democracy are least successful and measures of policy volatility and subjective perception of politics most successful as explanatory variables in cross country growth regressions
