occupational choice and the process of development this paper models economic development as a process of institutional transformation by focusing on the interplay between agents occupational decisions and the distribution of wealth because of capital market imperfections poor agents choose working for a wage over self employment and wealthy agents become entrepreneurs who monitor workers only with sufficient inequality however will there be employment contracts otherwise there is either subsistence or self employment thus in static equilibrium the occupational structure depends on distribution since the latter is itself endogenous we demonstrate the robustness of this result by extending the model dynamically and studying examples in which initial wealth distributions have long run effects in one case the economy develops either widespread cottage industry self employment or factory production employment contracts depending on the initial distribution in the other example it develops into prosperity or stagnation

how important is variability in consumer credit limits abstract using a large panel this paper first demonstrates that individuals gain and lose access to credit frequently the estimated credit limit volatility is larger than most estimates of income volatility and varies over the business cycle within a model variable credit limits create a reason for households to hold both high interest debts and low interest savings at the same time using the estimated credit volatility the model explains why around one third of american households engage in this credit card puzzle the approach also offers an important new channel through which financial system uncertainty can affect household decisions

the environment and emerging development issues development economics for the most part has failed to recognize renewable environmental resources as economic goods yet the lives of the poor in developing countries are intimately tied to the fate of their local common property resources soil fuel wood water and so on ignoring the loss of common property renewable resources via degradation centralization or privatization in calculations of net national product can mask the destruction of resources available to a country s poor behind the false appearance of a growing national economy this paper describes the difference between the problem of managing local common property resources in developing countries and the problem of protecting the global commons such as the atmosphere and oceans it outlines the calculations that would include the local commons in the national income accounting of capital assets and argues that the interests of those most dependent on the increasingly scarce local commons will be best served by placing control in their hands while the central government provides infrastructure and educational support to control the pollution of the global commons on the other hand the paper sketches a plan in which most countries would have a high incentive to participate a global allocation of limited tradable permits to discharge defined pollutants

an axiomatic characterization of yitzhaki s index of individual deprivation abstract this note presents and discusses a number of properties a measure of individual deprivation should satisfy the axioms we propose are necessary and sufficient to characterize yitzhaki s index of deprivation making the structure of the index more transparent

where does microfinance flourish microfinance institution performance in macroeconomic context abstract we study whether and how the success of microfinance institutions mfi s depends on the country level context in particular macroeconomic and macro institutional features understanding these linkages can make mfi evaluation more accurate and further can help to locate microfinance in the broader picture of economic development we collect data on 373 mfis and merge it with country level economic and institutional data evidence arises for complementarity between mfi performance and the broader economy for example mfis are more likely to cover costs when growth is stronger and mfis in financially deeper economies have lower default and operating costs and charge lower interest rates there is also evidence suggestive of substitutability or rivalry for example more manufacturing and higher workforce participation are associated with slower growth in mfi outreach overall the country context appears to be an important determinant of mfi performance mfi performance should be handicapped for the environment in which it was achieved

microfinance literature a sustainability level perspective survey abstract since the early microcredit programs up to the present microfinance has grown exponentially as it has the academic interest on it as a research subject considering that this sector has impact in terms of sustainability any research in the field requires an analysis with wide criteria which should include the economic environmental social and governance dimensions eesg as well as their interrelationships the objectives of this survey are to investigate the contributions of microfinance sectoral scholarly research to sustainability through a systematic literature review using content analysis method contextualizing the scientific production and studying its terminology according to the eesg criteria and under global reporting initiative framework and finally to identify research gaps and to propose future research paths

value function approximation in the presence of uncertainty and inequality constraints an application to the demand for credit cards abstract we present an algorithm for approximating the solution to discrete time stochastic dynamic programs with inequality constraints the algorithm exploits the state preference approach to choice under uncertainty to reduce the dimensionality of the state space and polynomial approximation to improve computational efficiency it is particularly useful in financial applications involving liquidity and credit constraints and more than one asset the algorithm provides information about the derivatives of the value function and therefore risk aversion along with asset demands

microfinance and poverty evidence using panel data from bangladesh micro finance supports mainly informal activities that often have low market demand it may be thus hypothesized that the aggregate poverty impact of micro finance in an economy with low economic growth is modest or nonexistent the observed borrower level poverty impact is then a result of income redistribution or short run income generation the author addresses these questions using household level panel data from bangladesh the findings confirm that micro finance benefits the poorest and has sustained impact in reducing poverty among program participants it also has positive spillover impact reducing poverty at the village level but the effect is more pronounced in reducing extreme rather than moderate poverty

distributional aspects of emissions in climate change integrated assessment models the recent failure of copenhagen negotiations shows that concrete actions are needed to create the conditions for a consensus over global emission reduction policies a wide coalition of countries in international climate change agreements could be facilitated by the perceived fairness of rich and poor countries of the abatement sharing at international level in this paper i use two popular climate change integrated assessment models to investigate the path and decompose components and sources of future inequality in the emissions distribution results prove to be consistent with previous empirical studies and robust to model comparison and show that gaps in gdp across world regions will still play a crucial role in explaining different countries contributions to global warming

international inequality in energy intensity levels and the role of production composition and energy efficiency an analysis of oecd countries abstract this paper analyses the inequality of energy intensity levels between oecd countries its causes and evolution the paper develops a methodology which allows the inequality in energy consumption per capita to be decomposed into explanatory factors it also analyses the contribution of different groups of countries to this inequality the results show that although differences in affluence are the most significant factor in explaining inequality in energy consumption per capita the inequality in energy intensity levels plays a prominent role in reducing the inequality in energy consumption per capita over the analysed period the paper also develops a methodology which determines the importance of different production structures and energy efficiency of productive sectors in the differences in energy use per unit of gdp between the countries analysed the results show that sector specialisation becomes increasingly important in explaining the inequality of energy intensity while there is a significant trend towards the convergence of energy efficiency between countries sector by sector this trend would explain the decreasing weight of energy intensity as an explanatory factor of the inequalities in energy consumption per capita

microfinance and poverty a macro perspective we test the hypothesis that microfinance reduces poverty at the macro level using cross country and panel data which are constructed by the microfinance information exchange data on microfinance institutions mfis and the world bank data taking account of the endogeneity associated with mfis loans we show that a country with higher mfis gross loan portfolio per capita tends to have lower levels of poverty indices contrary to recent micro evidence our results suggest that microfinance significantly reduces poverty at macro level and thus reinforce the case for channeling funds from development finance institutions and governments of developing countries into mfis

consumer rationality and credit cards borrowing on credit cards at high interest rates might appear irrational however even low transactions costs can make credit cards attractive relative to bank loans credit cards also provide liquidity services by allowing consumers to avoid some of the opportunity costs of holding money the effect of alternative interest rates on the demand for card debits can explain why credit card interest rates only partially reflect changes in the cost of funds credit card interest rates that are inflexible relative to the cost of funds are not inconsistent with a competitive equilibrium that yields zero profits for the marginal entrant

inequality democracy and institutions a critical review of recent research this paper surveys the theoretical and empirical literature on the effect of economic and political inequality on institutions the current understanding suggests that unequal societies develop exploitative and inefficient institutions empirical research which is scant and has mainly concentrated at cross national level supports to some extent the existence of an inverse relationship between inequality and institutions but more analysis is needed future empirical research should undertake country state and micro level analysis which are a necessary complement to aggregate level studies the effect of inequality could also take place indirectly through the influence of inequality on democratization

regional welfare disparities the case of the european union the regional welfare distribution in the european union between 1993 and 1998 is examined using several complementary methodologies the results obtained show a reduction in regional welfare disparities over the period analysed it is worth noting in this respect however that regional productivity differences prove to be the main determinant behind observed welfare inequality in the european context moreover there has also been a decline in regional bipolarization over the six year contemplated while the degree of observed intradistributional mobility is relatively low the empirical evidence presented nevertheless reveals the importance of variables such as the national component the spatial location the regional productive structure or the percentage of gdp devoted to investment or to r d expenditure in accounting for the dynamics of the distribution under analysis

is globalization reducing poverty and inequality abstract over the past 20 years or so india china and the rest of east asia experienced fast economic growth and falls in the poverty rate latin america stagnated the former soviet union central and eastern europe and sub saharan africa regressed but what are the net trends the neoliberal argument says that world poverty and income inequality fell over the past two decades for the first time in more than a century and a half thanks to the rising density of economic integration across national borders the evidence therefore confirms that globalization in the context of the world economic regime in place since the end of bretton woods generates more mutual benefit than conflicting interests this paper questions the empirical basis of the neoliberal argument

inequality across countries in energy intensities an analysis of the role of energy transformation and final energy consumption this paper analyzes the role of the energy transformation index and of final energy consumption per gdp unit in the disparities in energy intensity across countries in that vein we use a theil decomposition approach to analyze global primary energy intensity inequality as well as inequality across different regions of the world and inequality within these regions the paper first demonstrates the pre eminence of divergence in final energy consumption per gdp unit in explaining global primary energy intensity inequality and its evolution during the 1971 2006 period secondly it shows the lower albeit non negligible impact of the transformation index in global primary energy inequality thirdly the relevance of regions as unit of analysis in studying cross country energy intensity inequality and their explanatory factors is highlighted and finally how regions around the world differ as to the relevance of the energy transformation index in explaining primary energy intensity inequality

the role of uncertainty and expectations in modeling range land use strategies an application of dynamic optimization modeling with recursion abstract this paper presents a bio economic optimization modeling approach for the simulation of land use decision making by farmers faced with climatic uncertainties the approach is applied to the study of land use strategies on commercial ranches in namibia first we compare two models differing in their structure the first one is an inter temporal optimization model forward looking with perfect foresight while the second is recursive and it explicitly incorporates uncertainty in the decision making process second we point out the structural advantage of the recursive optimization model in its ability to simulate how decision makers perceptions on the occurrence of stochastic events alter land use strategies and their economic and ecological outcomes both models make use of a state and transition conceptual framework to depict the bio economic feedback we found that the incorporation of rainfall uncertainty in decision making is crucial when modeling land use strategies in highly variable ecological economic systems such as ranches in arid rain fed areas where knowledge of rainfall distribution is inaccurate due to lack of experience or climate change both farmers and rangelands would be better off by precautiously expecting low rainfalls finally our results show that minimizing herd size adjustment costs would support the establishment of sustainable land use strategies

interest rates in a credit constrained economy when households face credit constraints in an economy with inside as well as outside money stationary equilibrium real interest rates are below the household rate of time preference they also depend significantly upon household risk aversion the demand for inside versus outside money bank costs bank reserves inflation and the marginal productivity of capital and capital depreciation rates in addition changes in financial variables affect per capita capital and output to a greater extent when households are credit constrained copyright 1994 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

finance and income inequality what do the data tell us although there are distinct conjectures about the relationship between finance and income inequality little empirical research compares their explanatory power we examine the relationship between finance and income inequality for 83 countries between 1960 and 1995 because financial develop ment might be endogenous we use instruments from the literature on law finance and growth to control for this our results suggest that in the long run inequality is less when financial development is greater consistent with galor and zeira 1993 and banerjee and newman 1993 although the results also suggest that inequality might increase as financial sector development increases at very low levels of financial sector development as suggested by greenwood and jovanovic 1990 this result is not robust we reject the hypothesis that financial development benefits only the rich our results thus suggest that in addition to improving growth financial development also reduces inequality

can micro credit bring development abstract we examine the long run effects of micro credit on development in an occupational choice model similar to banerjee and newman jpe 1993 micro credit is modeled as a pure improvement in the credit market that opens up self employment options to some agents who otherwise could only work for wages or subsist micro credit can either raise or lower long run gdp since it can lower use of both subsistence and full scale industrial technologies it typically lowers long run inequality and poverty by making subsistence payoffs less widespread thus an equity efficiency tradeoff may be involved in the promotion of micro credit however in a worst case scenario micro credit has purely negative long run effects the key to micro credit s long run effects is found to be the graduation rate defined as the rate at which the self employed build up enough wealth to start full scale firms we distinguish between two avenues for graduation winner graduation of those who earn above average returns in self employment and saver graduation due to gradual accumulation of average returns in self employment long run development is not attainable via micro credit if winner graduation is the sole avenue for graduation in contrast if the saving rate and self employment returns of the average micro borrower are jointly high enough then micro credit can bring an economy from stagnation to full development through saver graduation thus the lasting effects of micro credit may partially depend on simultaneous facilitation of micro saving eventual graduation of the average borrower rather than indefinite retention should be the goal of micro banks if micro credit is to be a stepping stone to broad based development rather than at best an anti poverty tool

inequality of renewable energy generation across oecd countries a note abstract this study recommends the use of theil s second measure to investigate international renewable energy generation disparities this index permits disparities to be broken down within and between groups of countries in a reliable style an analysis of oecd countries for 1980 2011 shows some basic points first drop in renewable energy generation disparities is attributable both to within group and between group inequality components second between group inequalities are presently the key contributor to the inequality and further investigation on within group inequalities divulges the significant explanatory role played by north american european and asian and oceanian countries

an evaluation of does economic inequality breed political conflict studies contradictory findings that economic inequality may have a positive negative or no impact on political conflict are a puzzle for conflict studies three approaches have been used t o explain the inconsistent findings of the ei pc economic inequality political conflict nexus statistical modeling formal modeling and theory building because analysts have tended to possess different research skills these three approaches have been employed in isolation from one another singly however all three approaches have proved deficient and are unlikely to solve the ei pc puzzle the most fruitful approach is to combine the assumptions of the theory builders and the deductive approach of the formal modelers with the various empirical tests of the statistical modelers such an approach to the ei pc puzzle produces a crucial test of the deprived actor and rational actor theories of conflict the approach is also our best hope for solving the other long standing puzzles in conflict studies

weighting vectors and international inequality changes in environmental indicators an analysis of co2 per capita emissions and kaya factors abstract analyses of international inequality in environmental factors such as the well known co 2 per capita or the kaya factors that is carbon intensity energy intensity and affluence have overlooked the effect that weighting vectors of distance functions and their time variations can have on the evolution of the inequality observed thus for example increases in the relative weight of countries with low emissions tend ceteris paribus to increase the inequality even when the vector of international per capita emissions remains unchanged this effect strictly associated with share variations is assessed in this paper by means of a simple decomposition methodology this methodology allows us to ascertain what part of the time variation of the inequality is attributable to the variations in the shares and or the variations in the environmental variable analysed and in turn suggests extending the analysis to the group components of inequality shorrocks 1980 this proposition is used empirically to assess international inequalities in co 2 per capita and the kaya factors for a variety of sub periods during the 1971 2007 period and for various satisfactory inequality indices

inequality of energy intensities across oecd countries a note abstract this paper proposes the use of theil s second measure to analyze international energy intensity differences this index allows differences to be broken down within and between groups of countries in a consistent manner an analysis of oecd countries for the period 1971 1999 shows some basic points first the fall in energy intensities differences is attributable both to within group and between group inequality components second between group inequalities are currently the main contributor to the whole inequality value finally a detailed exploration on within group inequalities reveals the significant explanatory role played by eu countries

inequality in co2 emissions across countries and its relationship with income inequality a distributive approach this paper analyses the inequality in co2 emissions across countries and groups of countries and the relationship of this inequality with income inequality across countries for the period 1971 1999 the research employs the tools that are usually applied in income distribution analysis the methodology used here gives qualitative and quantitative information on some of the features of the inequalities across countries that are considered most relevant for the design and discussion of policies aimed at mitigating climate change the paper studies the relationship between co2 emissions and gdp and shows that income inequality across countries has been followed by an important inequality in the distribution of emissions this inequality has diminished mildly although the inequality in emissions across countries ordered in the increasing value of income inequality between rich and poor countries has diminished less than the simple inequality in emissions lastly the paper shows that the inequality in co2 emissions is mostly explained by the inequality between groups with different per capita income level the importance of the inequality within groups of similar per capita income is much lower and has diminished during the period especially in the low middle income group

financial performance and outreach a global analysis of leading microbanks microfinance contracts have proven able to secure high rates of loan repayment in the face of limited liability and information asymmetries but high repayment rates have not translated easily into profits for most microbanks profitability though is at the heart of the promise that microfinance can deliver poverty reduction while not relying on ongoing subsidy the authors examine why this promise remains unmet for most institutions using a data set with unusually high quality financial information on 124 institutions in 49 countries they explore the patterns of profitability loan repayment and cost reduction the authors find that institutional design and orientation matter substantially lenders that do not use group based methods to overcome incentive problems experience weaker portfolio quality and lower profit rates when interest rates are raised substantially for these individual based lenders one key to achieving profitability is investing more heavily in staff costs a finding consistent with the economics of information but contrary to the conventional wisdom that profitability is largely a function of minimizing cost

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

estimates of trends in global income and resource inequalities it is often argued that the inequality in the world is increasing we study the global income and resource inequality between 1960 and late 1990s income is measured in gdp capita in terms of both current market exchange rate and purchasing power parity ppp consumption of paper energy electricity food animal food as well as emissions of carbon dioxide is also studied changes in the absolute and relative gap between the top and bottom 20 consumers as well as the atkinson measure are used as inequality indicators some remarks are made on how to compare income across countries and how inequality should be measured we find that the inequality in terms of gdp capita measured in ppp terms is rather stable in relative terms but increasing in absolute terms we conclude that inequality as measured by the atkinson index is decreasing for all resources but that the gap in resource consumption in absolute terms is increasing for paper and electricity consumption

true world income distribution 1988 and 1993 first calculation based on household surveys alone the paper derives world income or expenditure distribution of individuals for two years 1988 and 1993 it is the first paper to calculate world distribution for individuals based entirely on household survey data from 91 countries and adjusted for differences in purchasing power parity between the countries measured by the gini index inequality increased from an already very high 63 in 1988 to 66 in 1993 the increase was driven more by rising differences in mean incomes between the countries than by rising inequalities within countries the most important contributors were rising urban rural differences in china and slow growth of rural incomes in south asia compared to several large developed market economies

educational expansion and the kuznets effect the objective in this note is to show the change in wage dispersion in response to increases in the relative supply of educated workers in two low income countries we also measure the relative contributions to that change of its two components the effect of the educational expansion on the educational composition of the labor force holding the educational structure of wages constant and the resultant compression of that structure holding composition constant the paper s analysis is based on three precisely comparable surveys of wage employees conducted in tanzania in 1971 and 1980 and in kenya in 1980

relative deprivation and economic welfare a statistical investigation with gini based welfare indices the average level of relative deprivation is considered as a measure of the economic welfare or standards of living for a society this approach yields welfare indices that are weighted combinations of the mean income and the gini coefficient there has been no systematic international comparison of these gini based welfare indices in this paper they are applied to compare relative deprivation and economic welfare using data from the luxembourg income study the asymptotic distributions of estimators of gini based welfare indices are provided under weighted sampling

renewal theory and natural resource regulatory policy under uncertainty abstract in this paper we show how renewal theory can be used to model a large class of natural resource regulatory problems involving systemic and policy uncertainty we stress the policy implications of our approach and then we suggest possible extensions

access to finance an unfinished agenda recent data compilations show that many poor and non poor people in many developing countries face a high degree of financial exclusion and high barriers in access to finance theory and empirical evidence point to the critical role that improved access to finance has in promoting growth and reducing income inequality an extensive literature shows the channels through which finance promotes enterprise growth and improves aggregate resource allocation there is less evidence at the household level however and on the effectiveness of policies to overcome financial exclusion the article summarizes recent efforts to measure and analyze the impact of access to finance and discusses the unfinished research agenda

aspects of the optimal management of cyclical ecological economic systems abstract we now know that from a functional standpoint jointly determined ecological economic systems ecosystems cycle over time however because this recognition has been recent the ecological economics literature contains very few formal studies of the management of cyclical ecosystems consequently the objective of this paper is to use renewal theory to examine two ways of analyzing the optimal management of cyclical ecosystems

global patterns of materials use a socioeconomic and geophysical analysis abstract human use of materials is a major driver of global environmental change the links between materials use and economic development are central to the challenge of decoupling of materials use and economic growth dematerialization this article presents a new global material flow dataset compiled for the year 2000 covering 175 countries including both extraction and trade flows and comprising four major material categories biomass construction minerals fossil energy carriers and ores industrial minerals first we quantify the variability and distributional inequality gini coefficients in international material consumption we then measure the influence of the drivers population gdp land area and climate this analysis yields international income elasticities of material use finally we examine the coupling between material flows and between income and material productivity measured in economic production per tonne material consumed material productivity is strongly coupled to income and may thus not be suitable as an international indicator of environmental progress a finding which we relate to the economic inelasticity of material consumption the results demonstrate striking differences between the material groups biomass is the most equitably distributed resource economically the most inelastic and is not correlated to any of the mineral materials the three mineral material groups are closely coupled to each other and economic activity indicating that the challenge of dematerializing industrial economies may require fundamental structural transformation our analysis provides a first systematic investigation of international differences in material use and their drivers and thus serves as the basis for more detailed future work

money and interest in a cash in advance economy the authors analyze an aggregative general equilibrium model in which the use of money is motivated by a cash in advance constraint applied to purchases of a subset of consumption goods the system is subject to both real and monetary shocks which are economy wide and observed by all they develop methods for verifying the existence of characterizing and explicitly calculating equilibria copyright 1987 by the econometric society

determinants of democracy a panel study of over 100 countries from 1960 to 1995 finds that improvements in the standard of living predict increase in democracy as measured by a subjective indicator of electoral rights the propensity for democracy rises with per capita gdp primary schooling and a smaller gap between male and female primary attainment for a given standard of living democaracy tends to fall with urbnization and with a greater reliance on natrual resources democracy has little relation to country size but rises with the middle class share of income the apparently strong relation of democracy to colonial heritage mostly disappears when the economic variables are held constant similarly the allowance for these economic variables weakens the interplay between democracy and religious affiliation however negative effects from muslim and non religious affiliations remain intact

does microfinance reduce income inequality this study addresses the question whether participation of the poor in microfinance contributes to reducing a country s level of income inequality using data from 70 developing countries we show that higher levels of microfinance participation are indeed associated with a reduction of the income gap between rich and poor people we also show however that the effects of microfinance on reducing income inequality are relatively small the results of this study add to the discussion on the impact of microfinance on poverty by showing that although access to microfinance does seem to improve the relative income position of the poor this improvement is modest which is probably because the use of microfinance is generally small as compared to the size of the economy of the countries in our sample microfinance should therefore not be seen as a panacea for bringing down income inequality in a significant way

the liquidity services of money this paper investigates the liquidity services provided by cash interest bearing check balances and securities which pay higher interest than checks securities must be traded before con sumers know their desired level or composition of consumption cash a nd checks are more liquid since they are available on demand cas h is more liquid than checks since it is more widely useable as a medium of exchange cash will often be used to buy goods which could be bought by check and the demand for cash will be less sensitive t han the demand for checks to the interest paid on check balances copyright 1988 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

does financial development contribute to poverty reduction the article examines the contribution of financial development to poverty reduction in developing countries building on earlier research which has established links between financial development and economic growth and between economic growth and poverty reduction the article tests for a causal process linking financial sector growth and poverty reduction the empirical results indicate that up to a threshold level of economic development financial sector growth contributes to poverty reduction through the growth enhancing effect the impact of financial development on poverty reduction will be affected however by any change in income inequality resulting from financial development

halving global poverty the goal of central importance to this paper is to cut in half the proportion of people living below 1 a day from around 30 percent of the developing world s population in 1990 to 15 percent by 2015 based on population projections in 1990 this would correspond to around one billion people exiting poverty this paper begins by discussing poverty trends on a global scale where the poor are located in the world and how their numbers have been changing over time it then discusses the relationship of economic growth and income distribution to poverty reduction finally it suggests an evidence based agenda for poverty reduction in the developing world full text available at official url

the failure of competition in the credit card market the bank credit card market containing 4 000 firms and lacking regulatory barriers casually appears to be a hospitable environment for the model of perfect competition nevertheless this article reports that credit card interest rates have been exceptionally sticky relative to the cost of funds moreover major credit card issuers have persistently earned from three to five times the ordinary rate of return in banking during the periods 1983 88 the failure of the competitive model appears to be partly attributable to consumers making credit card choices without taking account of the very high probability that they will pay interest on their outstanding balances copyright 1991 by american economic association

regional differences and the components of growth and inequality change abstract inequality change can be decomposed simply in terms of per capita income and population changes using the gini index an illustration based on u s data for the two intercensus periods 1960 1970 and 1970 1980 is given this decomposition analysis is also applied to the study of changes in a welfare index originally proposed by sen

do microfinance institutions fulfil their promise evidence from cross country data abstractthe concept of microfinance promises poverty reduction and economic growth we empirically challenge this economic and social promise in an attempt to prove its fulfilment our multivariate regressions of economic development variables such as per capita gross national income based on ppp converted to international dollars gni per capita ppp gdp growth as well as gross capital formation and labour participation rate against specific microfinance institutions mfi variables show that the success and performance of mfis significantly influence economic development microfinance directly influences economic growth through the value that mfi performance adds to purchasing power an indirect impact comes from an improvement in capital accumulation and employment rates these insights are valuable as the interdependencies between microfinance and economic development that this article verifies offer new and progressive insights into purposeful action that can be taken to stimulate economic develop

cost of business cycles with indivisibilities and liquidity constraints it is almost universally agreed that individuals face incomplete insurance markets and cannot perfectly insure against the idiosyncratic risk in this paper simple general equilibrium models with incomplete insurance markets are examined in order to assess the impact of imperfect insurance on the magnitude of the welfare costs of business cycles two versions of incomplete insurance markets are considered and certain statistical properties of the equilibrium stochastic processes in these environments are compared with those of a perfect insurance economy

tying odysseus to the mast evidence from a commitment savings product in the philippines we designed a commitment savings product for a philippine bank and implemented it using a randomized control methodology the savings product was intended for individuals who want to commit now to restrict access to their savings and who were sophisticated enough to engage in such a mechanism we conducted a baseline survey on 1777 existing or former clients of a bank one month later we offered the commitment product to a randomly chosen subset of 710 clients 202 28 4 percent accepted the offer and opened the account in the baseline survey we asked hypothetical time discounting questions women who exhibited a lower discount rate for future relative to current trade offs and hence potentially have a preference for commitment were indeed significantly more likely to open the commitment savings account after twelve months average savings balances increased by 81 percentage points for those clients assigned to the treatment group relative to those assigned to the control group we conclude that the savings response represents a lasting change in savings and not merely a short term response to a new product

how do income and education affect health inequality evidence from four developing countries using household survey data from four countries albania nepal tajikistan and tanzania this article calculates income related inequality in health care utilization we measure health disparity separately for generally and chronically ill individuals by constructing two models one for the probability of a visit to a physician and another for the number of visits following model based measurements we decompose inequality into two major parts one accounted for by identity related factors and another by socioeconomic and other factors such as education geography and distance to a clinic we propose a new method to quantify the effect of changes in income and education on health disparity one of our important findings suggests that health disparity is pro rich in all our sample countries the pro rich disparity is prevalent among generally ill as well as chronically ill patients in both visit probability and visit frequency models health inequality seems primarily driven by income differences foll

education growth and income inequality estimates of the effect of education on gdp the social return have been hard to reconcile with micro evidence on the private return to schooling we present a simple explanation combining two ideas imperfect substitution and endogenous skill biased technological progress and use cross country panel data on inequality and gdp to test these ideas a one year increase in the level of education reduces the private return by 2 percentage points consistent with katz murphy s 1992 elasticity of substitution we find no evidence for reversal of this initial effect as in acemoglu 2002 in the short run the social return equals the private return

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

experimental evidence on returns to capital and access to finance in mexico a strong theoretical argument for focusing on access to finance is that financial market imperfections can result in large inefficiencies as firms with productive investment opportunities underinvest lack of access to finance is a frequent complaint of microenterprises which account for a large share of employment in developing countries however assessing the extent to which a lack of capital affects their business profits is complicated by the fact that business investment is likely to be correlated with a host of unmeasured characteristics of the owner and firm such as entrepreneurial ability and demand shocks in a randomized experiment that gave cash and in kind grants to small retail firms providing an exogenous shock to capital the shock generated large increases in profits with the effects concentrated among firms that were more financially constrained the estimated return to capital was at least 20 33 percent a month three to five times higher than market interest rates

diet and the distribution of environmental impact abstract this paper examines the relationship between scale and distribution issues it is argued that since achieving a sustainable scale requires economic activity to stay within biophysical limits considerations of equity should not be limited to the distribution of monetary measures such as income but should include the distribution of scarce environmental services as well in order to make this point this paper examines how differences in diet across populations lead to inequality in the distribution of environmental impact first the distribution of food consumption across the world s population is examined using national data next ecological footprints are estimated in order to ascertain how differences in diet affect the distribution of environmental impact the results show that the meat intensive diet enjoyed by many in the industrialized world leads to a greater degree of inequality in the use of environmental services than is apparent from examination of the distribution of food consumption across countries

what do we know about global income inequality in this paper we review the recent literature on global interpersonal income inequality while all estimates agree that the level is very high with a gini of between 0 630 and 0 686 in the 1990s there is no consensus regarding the direction of change we discuss methodological issues including the use of national accounts versus survey based estimates of mean income or consumption and the choice of purchasing power parity exchange rates findings of a rise or fall in global income inequality are not robust across different estimation methods and datasets given the diversity of estimates and various sources of uncertainty including gaps and errors in the underlying data we conclude there is insufficient evidence to determine the direction of change in global interpersonal inequality in recent decades

money and banking in a cash in advance economy this paper studies banking and financial innovations in a stochasti c general equilibrium model assuming the existence of two distinct types of goods cash goods which can only be purchased by cash and check goods which can also be purchased by checks drawn against interest bearing bank accounts the authors analyze the effects of changes in the payment s structure i e the share of check goods reserve requirements on banks and changes in the supply of reserves the authors find e g that an increased share of check goods and a decrease of the bank reserve ratio in general both lead to a decrease in the variance of the price level copyright 1988 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association
