an environmental performance index for products reflecting damage costs abstract several studies have demonstrated how to use dea data envelopment analysis based techniques to estimate environmental performance indices none of these studies however are taking information on the environmental damage costs of the pressure types considered into account this study is bridging a gap between environmental indices founded in physical pressures and damage costs founded in welfare economics the aim of the paper is twofold first to demonstrate how to implement the information on environmental damage costs within a dea based environmental performance index and second to estimate these indices at product level by using danish input output data and environmental data from 1997

assessing regional eco efficiency from the perspective of resource environmental and economic performance in china a bootstrapping approach in global data envelopment analysis abstract eco efficiency has been receiving increasing attention across the world this paper proposes an extended data envelopment analysis model which combines global benchmark technology directional distance function and a bootstrapping approach to investigate the dynamic trends of regional eco efficiency in china from 2003 to 2014 moreover a developed slacks based measure is utilized to decompose the performance fluctuations into resource environmental and economic efficiency then the key factors responsible for the changes in eco efficiency are explored using the global malmquist luenberger index the empirical results demonstrate an upward trend of eco efficiency in china during the study period this trend was high in eastern and northern areas but low in northwestern areas however it should be noted that some eco efficient regions still consume much land water and energy and emit much environmental pollutants in absolute terms the whole of china performs well on the economic front while resource and environmental performances are not encouraging particularly on environmental efficiency the eastern and northern regions have experienced the greatest advances in both resource and environmental efficiency while the undeveloped areas have not shown much progress which further widens the gaps between developed areas and undeveloped areas the decomposition of productivity growth indicates that technical progress is the decisive factor in promoting china s eco efficiency while decreasing management level is the major obstacle hampering the improvement in eco efficiency

sufficiency or efficiency to achieve lower resource consumption and emissions the role of the rebound effect a frequent criticism of eco efficiency strategies is that an increase in efficiency can be offset by the rebound effect sufficiency is discussed as a new strategy involving self imposed restriction of consumption but can also be subject to the rebound effect we show that the range of possible secondary effects of efficiency and sufficiency strategies goes beyond the rebound effect the rebound effect can indeed also be linked to eco sufficiency strategies but there are further secondary effects of both eco efficiency and eco sufficiency strategies such as double dividend effects we develop an eco efficiency sufficiency matrix to logically order eco efficiency and sufficiency measures to attain lower resource consumption and emissions

distorted agricultural incentives and economic development asia s experience earnings from farming in many low income countries have been depressed by a pro urban bias in own country policies as well as by governments of richer countries favouring their farmers with import barriers and subsidies both sets of policies reduce national and global economic welfare the rapid development of many asian emerging economies has been accompanied by a gradual reduction in their anti agricultural policies but many distortions remain and some countries have moved from negative to positive assistance for farmers following the earlier examples of first japan and then korea and taiwan drawing on results from a new multi country research project this paper examines the extent of these changes relative to those of other developing countries over the past five decades it concludes by pointing to prospects for further policy reform in asia

investment subsidies and pro poor growth in rural india this article reviews the trends in government subsidies and investments in and for indian agriculture develops a conceptual framework and a model to assess the impact of various subsidies and investments on agricultural growth and poverty reduction and presents reform options with regard to re prioritizing government spending subsidies in credit fertilizer and irrigation have been crucial for small farmers to adopt new technologies particularly during the initial stage of the green revolution in the late 1960s and 1970s but it is now investments in agricultural research education and rural roads that are the three most effective public spending items in promoting agricultural growth and reducing poverty

targeting maps an asset based approach to geographic targeting summary proper targeting of policy interventions requires reasonable estimates of the benefits of the alternative options to inform such decisions we develop an integrated approach stemming from the small area estimation literature that estimates the marginal returns to a range of assets across geographically defined subpopulations we create a series of maps that can be overlaid with traditional poverty maps to identify strong candidate areas for intervention though an efficiency equity tradeoff sometimes exists we apply our method using recent ugandan data results are consistent with independent empirical findings and suggest asset specific transfer schemes would improve with a spatially targeted strategy

the economics of poverty traps and persistent poverty an asset based approach abstract longitudinal data on household living standards open the way to a deeper analysis of the nature and extent of poverty while a number of studies have exploited this type of data to distinguish transitory from more chronic forms of income or expenditure poverty this paper develops an asset based approach to poverty analysis that makes it possible to distinguish deep rooted persistent structural poverty from poverty that passes naturally with time due to systemic growth processes drawing on the economic theory of poverty traps and bifurcated accumulation strategies this paper briefly discusses some feasible estimation strategies for empirically identifying poverty traps and long term persistent structural poverty as well as relevant extensions of the popular foster greer thorbecke class of poverty measures the paper closes with reflections on how asset based poverty can be used to underwrite the design of persistent poverty reduction strategies

do free goods stick to poor households experimental evidence on insecticide treated bednets summary if the market allocates goods to those willing and able to pay the most for them efforts to target durable health goods such as insecticide treated bednets itns to poor populations may prove ineffective with the poor reselling donated goods to the non poor who value them more highly however low market demand may be due to liquidity constraints rather than low valuation of nets the endowment effect also militates against the resale of in kind transfers we quantify these two effects through a field experiment in uganda our results indicate that very few nets will be resold by recipient households

transfers in cash and in kind theory meets the data we review theoretical explanations for in kind transfers in light of the limited empirical evidence after reviewing the traditional paternalistic arguments we consider explanations based on imperfect information and self targeting we then discuss the large literature on in kind programs as a way of improving the efficiency of the tax system and a range of other possible explanations including the samaritan s dilemma pecuniary effects credit constraints asymmetric information amongst agents and political economy considerations our reading of the evidence suggests that paternalism and interdependent preferences are leading overall explanations for the existence of in kind transfer programs but that some of the other arguments may apply to specific cases political economy considerations must also be part of the story

unpacking the meaning of market access evidence from rural kenya summary this paper critically examines the dimensions of market access using farm panel survey data from kenya we investigate changes in ten indicators of market access during the 1997 2010 post liberalization period we find major improvements in certain market access conditions and little change in others there is generally low correlation between alternative indicators of market access all purpose indicators may not accurately reflect specific market access conditions of interest distances to physical infrastructure are often not representative of farmers access to markets changes in specific market access conditions may have more to do with the behaviors of marketing agents we consider the implications of these findings for agricultural marketing policies and for research methods

new markets and technological change for the traditional cereals in semiarid sub saharan africa the malian case during the last three decades in sub saharan africa development and research resources have concentrated on the higher rainfall and irrigated regions especially on export crops and the principal food crops grown there there has been much less concern and investment in semiarid regions without irrigation another negative factor has been the lack of public policy concern with the profitability of the basic food crops with good weather prices collapse with bad weather governments and ngos dispense food crops as food aid or at subsidized prices this article documents the importance of the demand side to facilitate diffusion of new technologies for the basic food commodities of semiarid regions the traditional cereals with farm programming models aggregated into a sector model the combination of technological change and demand shifts for sorghum are evaluated in one semiarid region where the traditional cereals are concentrated it focuses on combining policies to increase the prices farmers receive after introduction of technologies that use higher input levels it also compares benefits of a strategy that focuses on yield and demand increases for a traditional cereal of the semiarid region sorghum with two alternative strategies for the higher rainfall zone

a literature study for dea applied to energy and environment abstract this study systematically summarizes previous research efforts on data envelopment analysis dea applied to energy and environment in the past four decades including concepts and methodologies on dea environmental assessment industrial developments are very important for all nations in terms of their economic prosperities a problem is that the development produces various pollutions on air water and other types of contaminations all of which are usually associated with our health problems and climate changes thus it is necessary for us to consider how to make a balance between economic success and pollution mitigation to maintain a high level of social sustainability in the world it is widely considered that dea is one of the methodologies to examine the level of sustainability this study examines a recent research trend on dea applications from 1980s to 2010s nowadays many researchers have paid serious attention on how to combat various difficulties in the areas of energy and environment as a result the number of articles on dea applications on energy and environment has dramatically increased particularly after 2000s however it is true that dea has strengths and drawbacks in the applications therefore it is very important for us to carefully use dea for guiding large policy issues and business strategies such as the global warming and climate change an underlying premise of this study is that technology innovation in engineering and natural science may solve various problems by linking it with political and managerial efforts the use of dea provides a methodological linkage among them so enhancing the practicality in mitigating problems due to climate change and environmental pollutions this literature study along with a summary on conceptual and methodological developments provides us with guidelines for our future research works on dea on energy and environment issues

government and the decentralization of r d abstract the purpose of this article is to show how costs and benefits of geographical decentralization of r d can be identified and compared the benefits for the region that receives r d activities are studied in section 2 they stem from the short run multiplier effect the amelioration of human capital and the possible modernization of the local industrial structure on the cost side examined in section 3 the observable impacts of the decentralization of r d concern the loss of returns to scale and urban economies of the production of the r d output it is shown in section 4 that the flows of costs and benefits must be discounted by the social cost of capital the main conclusion of this article is that the decentralization of r d in a large sparsely populated country entails social costs and this would weaken its competitive position in world commerce on the other hand the issue of decentralization is more crucial for small countries in terms of population and economic size than for large ones like the u s where critical masses of research efforts can be simultaneously attained in many fields and in many places

ranking farms with a composite indicator of sustainability the assessment of sustainability at farm level has been growing in popularity over the last few years this article contributes to this line of research by building up composite indicators for different facets social economic environmental and global of farm sustainability using a methodological approach that combines data envelopment analysis dea and multicriteria decision making mcdm methods and assigns common weights to each individual sustainability indicator this approach is applied to a database of 163 farms located in the campos county a region belonging to the dry lands of the spanish northern plateau using 12 individual indicators of sustainability our findings show that both economic and environmental composite sustainability indicators are positively correlated but that this is not the case for the social indicator we also check the influence of a set of variables on farm sustainability using bootstrapping statistical techniques and showing that increasing farm size membership in agricultural cooperatives and farmers medium and upper agricultural specific technical education all exert a significant positive influence on sustainability these results provide clues for policy makers that intend to design sustainability increasing structural agricultural policies

the environmental performance of dutch government bond funds we investigate the implications of using different indicators to assess the sustainability performance of investment funds in particular we look into the environmental performance of dutch government bond funds we find that it does matter a lot which particular indicator is used this suggests that funds should be very transparent and straightforward about their non financial performance we argue that basically they have three options first the industry comes up with a benchmark against which the responsibility of their investments is measured and reported by all funds second the funds make very clear and transparent which particular aspects of sustainability they specifically target and how they keep score third the dashboard approach where the funds report their performance on a well defined set of indicators

targeting public investments by agro ecological zone to achieve growth and poverty alleviation goals in rural india abstract this paper shows that improved technology and rural infrastructure have made important contributions to agricultural growth and poverty reduction in india however these effects have varied widely across agro ecological zones in the past the government has devoted more resources to irrigated areas and this has led to significant production growth and poverty reduction in those areas however as investments in irrigated areas continue to increase their marginal returns diminish and it is now in many of the rainfed areas including some of lower agricultural potential where the marginal returns from additional government investments in technology and infrastructure are largest

it pays to be green a premature conclusion it has been claimed that good environmental performance can improve firms economic performance however because of e g data limitations the methods applied in most previous quantitative empirical studies on effects of environmental performance on economic performance of firms suffer from several shortcomings we discuss these shortcomings and conclude that previously applied methods are unsatisfactory as support for a conclusion that it pays for firms to be green then we illustrate the consequences of these shortcomings by performing several regression analyses of the effect of environmental performance on economic performance using a panel data set of norwegian plants a pooled regression where observable firm characteristics like e g size or industry are controlled for confirms a positive effect of environmental performance on economic performance however the estimated positive effect could be due to omitted unobserved variables like management or technology when the regression model controls for unobserved plant heterogeneity the effect is generally no longer statistically significant hence although greener plants tend to perform economically better the analysis provides little support for the claim that it is because they are greener these empirical findings further indicate that a conclusion that it pays to be green is premature

multilateral productivity comparisons when some outputs are undesirable a nonparametric approach multilateral productivity comparisons of firms producing multiple outputs some of which are undesirable are obtained by making two modifications to the standard farrell approach to efficiency measurement the restriction that production technology satisfy strong disposability of outputs is relaxed to allow for the fact that undesirable outputs may be freely disposable and the efficiency measures are modified to allow for an asymmetric treatment of desirable and undesirable outputs performance measures that satisfy these requirements are calculated as solutions to programming problems the methodology is applied to a sample of mills producing paper and pollutants

local governance and the quality of local infrastructure evidence from village road projects in rural china abstract research has shown that allowing local communities to elect their own leaders increases local infrastructure investment however much less is known about the effects of local governance reform on the quality of local infrastructure this paper examines the effects of governance reform implemented in rural chinese villages on the quality of village road projects we conduct surveys in 101 rural villages and collect data related to the implementation of the reform over the last two decades we also measure the quality of over 550 village road projects completed in these villages using fixed effects and instrumental variable estimation methods we find that the implementation of village governance reform increases the quality of village road projects we also find evidence supporting the following effect mechanisms 1 village leaders become younger and more educated 2 high quality road projects increase incumbent leaders re election chances and 3 village residents participate more actively in the management and monitoring of village road projects

agricultural growth poverty reduction and agro ecological zones in india an ecological fallacy abstract in an article in this journal that is part of an oevre that has been widely cited shenggen fan peter hazel and t haque 2000a present evidence that government investments in india now have greater effects on poverty in rainfed than irrigated regions this note suggests that parts of the methodology on which this claim is based are unclear and possibly suffer from an ecological fallacy even after clarification of their method by the authors some doubts remain as to whether the results quoted support the original claim

rural poverty and relative prices in india this paper begins with the observation that there has been a trend decline albeit small in rural poverty during 1956 83 but this is obscured by the substantial short run fluctuations around the trend it argues that while the trend is attributable to redistributive policies the short run fluctuations are adequately explained by the fluctuations in agricultural output and in relative prices of agricultural products vis a vis manufactures in view of the finding that rising relative agricultural prices increase rural poverty the paper goes on to analyze the process of determination of relative prices this analysis highlights the characteristics of the inflationary process and the role of agricultural price policy in the indian economy copyright 1989 by oxford university press

productivity growth in indian agriculture is there evidence of convergence across states this paper explores the question of convergence in total factor productivity tfp in agriculture across fourteen major agricultural states of india using a tornqvist theil index for tfp growth for the period 1973 1993 we find no evidence to support convergence to a single tfp level convergence after grouping the various states on the basis of their productivity performance we find that the high performing states show a gradual movement towards the trend whereas the low performing states generally show more volatility testing for long run convergence in levels of agricultural productivity we find evidence of conditional beta convergence after controlling for state specific factors and idiosyncratic year specific volatility the results are robust to alternative specifications of tests of unit root in panel data developed recently

returns to investment in less favored areas in developing countries a synthesis of evidence and implications for africa abstract a large proportion of world s population lives in marginal or less favored areas these areas are of home to the poorest segment of the population particularly in rural areas in the past government has targeted their resources mostly to the high potential or irrigated areas these investments have generated rapid growth in agricultural production for example the so called green revolution in south and southeast asia in the 1970s and 1980s which in turn has helped to alleviate rural and urban poverty however as investments continue to increase in these favored areas their marginal returns have begun to decline and environmental problems are emerging evidence shows that it is in the marginal areas or less favored areas where many investments may have higher returns today these investments may have even larger impacts on poverty reduction and environmental protection as poor people are increasingly concentrated in the marginal areas where natural resources have already been severely degraded this study synthesizes some recent studies from india and china on the relative returns to investments in favored and less favored areas and presents some preliminary evidence from uganda and offers some policy implications for africa on how governments and international donors can reprioritize their investment portfolio in order to achieve multiple goals of growth poverty reduction and environmental protection

capital theory and the measurement of sustainable development an indicator of weak sustainability the measurement of sustainable development is not without considerable difficulties yet this should not detract from the positive advances that can be made in this direction in this paper we present one form that a weak sustainability indicator can take derived from a simple but intuitive savings rule it incorporates the idea that the level of overall capital stock should be non decreasing although subject to qualification at this stage some interesting results emerge from the application of the rule to 18 countries

measuring farm sustainability and explaining differences in sustainable efficiency abstract a major objective of european agricultural policy is to have a sustainable and efficient farming sector that is applying environmentally friendly production methods policy makers aim to combine a strong economic performance and a sustainable use of natural resources therefore it is important to measure and to assess farm sustainability for a large dataset of flemish dairy farms a valuation method that is based on the concept of opportunity costs is used to calculate and analyze differences among the sample farms with respect to the creation of sustainable value but more important than measuring the creation of sustainable value is to analyze differences in sustainable efficiency therefore sustainable efficiency measures are calculated and differences in sustainable efficiency are explained using panel data an effect model captures the determinants of sustainable efficiency of the studied farms the empirical model shows that in general larger farms have a higher sustainable efficiency also farmer s age and dependency on support payments proved to be determining characteristics for observed differences in sustainable efficiency

productivity transport costs and subsistence agriculture abstract a defining feature of many poor economies is the large fraction of workers engaged in subsistence agriculture we develop a multi sector multi region model of a poor economy in which it is costly to transport goods across regions in order to study this outcome a key finding is that higher transport costs drive up the size of the agricultural workforce and the fraction in subsistence in a calibrated version of our model we show that the effect of transport productivity is quantitatively important in terms of both allocations and welfare

production prices and poverty in rural india this paper challenges the view that increases in agricultural production have reduced poverty in rural india rural poverty is related directly to the consumer price index number for agricultural labourers and inversely to agricultural production the underlying time trend term indicates a residual rising trend in rural poverty after accounting for the influence of these two factors there are plausible though conjectural reasons for believing that to a significant extent the price factor as well as the variables implicit in the time trend term both derive their strength if not their existence from the nature of the growth processes which have generated the observed growth in agricultural production these results contradict ahluwalia s earlier conclusions even though they are themselves based on essentially the same data set

between ostrom and nordhaus the research landscape of sustainability economics abstract we survey the emerging research area of sustainability economics through a quantitative full text analysis of peer reviewed journal publications from 1987 to 2013 to identify relevant contributions we draw on existing definitions of sustainability economics for a keyword based identification strategy a combined focus on a the human nature relationship b the long term uncertain future c normative orientation towards sustainability and d economic analysis our analysis of a random subsample of 343 relevant papers reveals that i sustainability economics is a rapidly developing research area ii while theoretical contributions shaped the area in earlier years applied work now constitutes the largest share of contributions iii the research landscape can be clustered into eleven research clusters these range from participatory governance of social ecological systems associated with the work of elinor ostrom to questions of intertemporal allocation and distribution applied to climate economics associated with the work of william nordhaus iv the research area is broad in scope and heterogeneous and there is relatively little interaction between important clusters v relevant contributions are published in more than 100 journals ten journals publish half of all contributions led by ecological economics and 40 appear in non economics journals underscoring the importance of interdisciplinary dialogue

how productive is infrastructure a new approach and evidence from rural india there have been competing arguments about the effect of public infrastructure on productivity level based and debate based regressions often lead to different estimates to help reconcile this difference this article applies the gmm method to first test for causality to check for length of lagged relationships and the existence of reverse causality before specifying a final model and deciding the estimation procedure this approach is illustrated using a panel data set for india the results show that infrastructure development in india is productive providing supporting evidence to reverse the trend of declining investment in rural infrastructure

analysis of environmental efficiency variations a nutrient balance approach recent literature has argued that environmental efficiency ee which is built on the materials balance mb principle is more suitable than other ee measures in situations where the law of mass conversation regulates production processes in addition the mb based ee method is particularly useful in analysing possible trade offs between cost and environmental performance identifying determinants of mb based ee can provide useful information to decision makers but there are very few empirical investigations into this issue this article proposes the use of data envelopment analysis and stochastic frontier analysis techniques to analyse variation in mb based ee specifically the article develops a stochastic nutrient frontier and nutrient inefficiency model to analyse determinants of mb based ee the empirical study applies both techniques to investigate mb based ee of 96 rice farms in south korea the size of land fertiliser consumption intensity cost allocative efficiency and the share of owned land out of total land are found to be correlated with mb based ee the results confirm the presence of a trade off between mb based ee and cost allocative efficiency and this finding favouring policy interventions to help farms simultaneously achieve cost efficiency and mp based ee

creating an enabling environment policy conditions for less favored areas abstract within the rural areas those with a low productive potential usually home to poor agricultural households with limited access to assets are often the core of rural poverty and under constant threat of resource degradation there is ample evidence that neither trickle down effects in high potential areas nor structural adjustment measures have generated much poverty reduction in these less favored areas lfas often due a lack of attention to the development of factor and commodity markets sustainable and pro poor development of lfas therefore poses formidable challenges and requires special measures to achieve an enabling institutional and policy environment it needs to be based on viable sources of growth that imply considerable investments in physical and human capital and appropriate technology recognize positive externalities and add equity and natural resource management concerns in a context of heterogeneity to establish policy conditions that favor such development the role of and experience with major policy interventions incentives and institutions relevant to lfas is reviewed and an attempt is made to generalize these findings to this effect the different interventions are grouped into three broad categories viz price and market policies public services and investment and institutions and governance while countries should adopt the relevant market and trade policies the case is made for greater awareness of the adverse impact these policies can have in lfas and on their poor and complementary policies and investments need to be put in place to buffer or offset adverse outcomes key complementary interventions include public investments in infrastructure human capital and technology to enhance the competitiveness of lfas and policies to improve their market access there is also need for appropriate phasing of policy and market reforms to give people time to adjust and effective safety nets to cushion loss of livelihood options

government spending growth and poverty in rural india using state level data for 1970 93 a simultaneous equation model was developed to estimate the direct and indirect effects of different types of government expenditure on ruralpoverty and productivity growth in india the results show that in order to reduce rural poverty the indian government shoul d give highest priority to additionalinvestments in ruralroads and agricul turalresearch these types of investment not only have much larger poverty impacts per rupee spent than any other government investment but also generate higher productivity growth apart from government spending on education which has the third l argest marginalimpact on ruralpoverty and produc

the road to specialization in agricultural production evidence from rural china summary many rural poor in developing countries live in areas far away from markets and isolation is a key limiting factor to their livelihood in this paper we use four waves of a primary panel household survey conducted in 17 remote natural villages in china to study how road access shapes farmers production patterns input use and rural poverty we adopt a difference in difference approach by comparing the outcomes of the households in villages with and without road access before and after the introduction of each road our results show that access to roads facilitates specialization in agricultural production in natural villages with better road access farmers plant fewer numbers of crops purchase more fertilizer and hire more labor consequently road connections improve household agricultural income and reduce poverty in addition road access significantly increases local nonfarm income for the relatively poor households but not the rich overall our research provides empirical justification on the importance of rural road on agricultural specialization and poverty reduction especially in isolated and impoverished regions

poverty agricultural production and prices in rural india a reformulation the empirical analysis at the all india level demonstrates that while the level of agricultural production and rural poverty were inversely related unanticipated consumer price increases aggravated rural poverty whether the advent of the new agricultural technology in the late 1960s altered the relationships in question is also considered during the new technology phase the coefficient of agricultural production ceased to be significant while that of unanticipated price changes continued to be significant rationalization of the absence of a significant inverse relationship between rural poverty and agricultural production at the state level in terms of distress migration between neighboring states is questioned and an alternative explanation is provided copyright 1989 by oxford university press

value standards in sub sustainable development on limits of ecological economics abstract sustainable development is hard to conceptualize as an economic problem and an economic problem is also ambiguous thus there is room for several kinds of ecological economics this paper analyses different ways of relating ecological and economical thinking to each other and how expertise in these fields relates to politics available methods are delimited in scope where some are suitable for the analysis of sustainable development and others are not it is concluded that the promotion of sustainable development as a basic value assumes an explicit value strategy it is argued that neoclassical economics for example cost benefit analysis is suitable for analysis of sustainable development only as a special case and alternatives are at hand for other cases to illustrate a non neoclassical analysis an empirical investigation using the sustainable development records approach is briefly reported upon

from policy aims and small farm characteristics to farm science needs this paper examines the agricultural science needs of small farms the green revolution successfully negotiated two tightropes agricultural productivity increases were larger than the fall in prices that resulted from producing more food and output per hectare rose faster than output per worker thus increasing the demand for labor the current challenge is to generate technology that helps poor farmers in low potential areas since research capacity is increasingly private incentives to produce the needed technology are needed perhaps through contracts to produce varieties with specific characteristics development of seeds needs complementary work on water for which economists plant scientists and engineers need to pool their skills

an aggregate resource efficiency perspective on sustainability a sustainable value application to the eu 15 countries the sustainable value approach integrates the efficiency with regard to environmental social and economic resources into a monetary indicator it gained significant popularity as evidenced by diverse applications at the corporate level however its introduction as a measure adhering to the strong sustainability paradigm sparked an ardent debate this study explores its validity as a macroeconomic strong sustainability measure by applying the sustainable value approach to the eu 15 countries concretely we assessed environmental social and economic resources in combination with the gdp for all eu 15 countries from 1995 to 2006 for three benchmark alternatives the results show that several countries manage to adequately delink resource use from gdp growth furthermore the remarkable difference in outcome between the national and eu 15 benchmark indicates a possible inefficiency of the current allocation of national resource ceilings imposed by the european institutions additionally by using an effects model we argue that the service degree of the economy and governmental expenditures on social protection and research and development are important determinants of overall resource efficiency finally we sketch out three necessary conditions to link the sustainable value approach to the strong sustainability paradigm

exploring poverty traps and social exclusion in south africa using qualitative and quantitative data abstract recent theoretical work hypothesises that a polarised society like south africa will suffer a legacy of ineffective social capital and blocked pathways of upward mobility that leaves large numbers of people trapped in poverty to explore these ideas this paper employs a mix of quantitative and qualitative methods novel econometric analysis of asset dynamics over the 1993 98 period identifies a dynamic asset poverty threshold that signals that large numbers of south africans are indeed trapped without a pathway out of poverty qualitative analysis of this period and the period 1998 2001 more deeply examines patterns of mobility and confirms the continuation of this pattern of limited upward mobility and a low level poverty trap in addition the qualitative data permit a closer look at the specific role played by social relationships while finding ample evidence of active social capital and networks these are more helpful for non poor households for the poor social capital at best helps sta

empowering rural people for their own development abstract this elmhirst lecture first discusses the features of the institutional environment which allow rural people in low income countries to design plan and implement their own rural development these are divided into two broad groups the institutional environment for rural development environment for the private sector communities and civil society local government and sector institutions and the many factors governing profitability of investment in agriculture while in many poor countries the institutional environment has improved over the last 20 years the most poorly performing countries still have by far the poorest environment for local government in the world within an empowering institutional environment the rate of agricultural and rural development is determined by investments of many different types that in turn depend primarily on the profitability of agriculture the paper discusses the large number of factors which determine profitability few of these are under the direct control of farmers or agricultural sector institutions but depend on governance and investments in other sectors such as trade and transport in many of the poorest countries there has been considerable improvement in macro economic management and sector policies over the past 20 years but progress in international and intra regional trade policies in agricultural trade policies in transport infrastructure and in agricultural research and extension have been limited

growth options and poverty reduction in ethiopia an economy wide model analysis abstract this study focuses on which agricultural subsectors are important in ethiopia s economic growth and poverty reduction and what kind of agricultural and nonagricultural growth is needed to achieve the millennium development goal of halving the incidence of poverty by 2015 a spatially disaggregated economy wide model was developed enabling the analysis of growth and poverty reduction linkages at national and regional levels using national household surveys agricultural sample surveys geographic information systems and other national and regional data the study reveals that agriculture can play a central role in decreasing poverty and increasing growth in ethiopia within the agriculture growth in cereals and other staple crops should receive priority agricultural growth also requires concurrent investments in roads and other market conditions at the subnational level similar growth rates within agricultural subsectors have different effects on poverty necessitating regionally based strategies for growth and poverty reduction

rural livelihoods and poverty reduction strategies in four african countries this paper compares and contrasts rural livelihoods in uganda kenya tanzania and malawi with a view to informing rural poverty reduction policies within poverty reduction strategy plans prsps low household incomes in rural areas of all countries are associated with low land and livestock holdings high reliance on food crop agriculture and low monetisation of the rural economy these adverse factors are in some instances made more difficult by land sub division at inheritance declining civil security in rural areas deteriorating access to proper agronomic advice and inputs and predatory taxation by decentralised district councils better off households are distinguished by virtuous spirals of accumulation typically involving diverse livestock ownership engagement in non farm self employment and diversity of on farm and non farm income sources lessons for prsps centre on the creation of a facilitating rather than blocking public sector environment for the multiplication of non farm enterprises seeking creative solutions to the spread of technical advice to farmers and examining critically the necessity for and impact of tax revenue collection by district councils on rural incomes and enterprise

the effects of rural electrification on employment new evidence from south africa this paper estimates the impact of electrification on employment growth by analyzing south africa s mass roll out of electricity to rural households using several new data sources and two different identification strategies an instrumental variables strategy and a fixed effects approach i find that electrification significantly raises female employment within five years this new infrastructure appears to increase hours of work for men and women while reducing female wages and increasing male earnings several pieces of evidence suggest that household electrification raises employment by releasing women from home production and enabling microenterprises migration behavior may also be affected jel h54 l94

income and the environment in rural india is there a poverty trap we study the relationships between rural income distributions and changes in environmental conditions in southern western and central india between 1994 95 and 2000 01 other than the relatively rich we find that all income strata benefit from an improved environment and intermediate expenditure households benefit more than the very poor in absolute terms higher median consumption expenditures and richness are estimated to increase environmental decline but we do not find a significant impact of income poverty on local environmental health the results do not support the poverty trap conjecture with environmental degradation driving expenditure reductions that promote offsetting aforestation which benefits the poor

the wider impacts of high technology employment evidence from u s cities abstract innovative high technology industries are commonly described as drivers of regional development tech workers earn high wages but they are also said to generate knock on effects throughout the local economies that host them spurring growth in jobs and wages in nontradable activities at the same time in iconic high tech agglomerations like the san francisco bay area the home of silicon valley the success of the tech industry creates tensions in part as living costs rise beyond the reach of many non tech workers across a large sample of u s cities this paper explores these issues systematically combining annual data on wages employment and prices from the quarterly census of employment and wages the department of housing and urban development and the consumer price index it estimates how growth in tradable tech employment affects the real living cost deflated wages of local workers in nontradable sectors results indicate that high technology employment has significant positive but modest effects on the real wages of workers in nontradable sectors these effects appear to be spread consistently across different kinds of nontradable activities in terms of substantive wider impacts tech appears benign though fairly ineffectual

what has luck got to do with it a regional analysis of poverty and agricultural growth in rural india this article explores the role of agro ecological factors associated with agricultural growth and poverty outcomes in india using a new operationalisation of agro ecological factors and incorporating within state variations in poverty and other variables we show that agricultural growth and poverty reduction appear to depend on underlying agro ecological conditions which are favourable to the spread of irrigation and hence agricultural development which in turn in associated with poverty reduction promotion of agriculture in less favoured areas in unlikely to have similar effects on agriculture in less favoured areas is unlikely to have similar effects on agricultural growth even if the effects of agricultural growth on poverty remain similar unless conditions for irrigation are favourable or rainfall is sufficiently abundant and reliable this suggests that considerable caution may be needed in drawing policy conclusions from empirical analysis by state alone and without regard to their underlying f

geographical targeting for poverty alleviation an introduction to the special issue in the face of rising public deficits and shrinking public resources geographical targeting may be a viable way to allocate resources for poverty alleviation in developing countries efficiency can be increased and leakage to the non poor reduced substantially by targeting increasingly smaller areas this article and more generally the symposium on geographical targeting for poverty alleviation proposes several techniques for augmenting data to produce more detailed poverty maps it focuses on practical considerations in the design of geographically targeted poverty alleviation programs in particular it assesses the advantages and disadvantages of geographical targeting and describes how geographic information systems can be applied to improve poverty mapping

one kind of freedom poverty dynamics in post apartheid south africa abstract a 1993 south african living standards survey documented the legacy of apartheid in the form high levels of inequality and human insecurity drawing on a 1998 re survey of households in the 1993 study this paper explores whether this legacy has been superseded or whether apartheid s end has been only one kind of freedom that has left households in a poverty trap from which they cannot escape after proposing a theoretically grounded dynamic poverty typology that distinguishes stochastic from structural poverty transitions the paper goes on to estimate that significant numbers of the south african poor are potentially trapped in a structural poverty trap and lack the means to escape poverty over time

plant breeding and poverty can transgenic seeds replicate the green revolution as a source of gains for the poor 1 abstract improved farm technology helps all main groups of the poor small farmers farmworkers other low wage labour when it raises labour value productivity but raises land and or water value productivity faster and cuts staples prices but raises smallholders total factor productivity faster from 1965 the green revolution walked these two tightropes largely by luck though targeting bigger piles of rice and wheat it cut poverty through consumption nutrition smallholder income employment risk reduction and ecological sustainability yet large areas were left out and from 1985 progress slowed in the new environment for research and agriculture how can transgenics revive and spread poverty reduction what has been the evidence so far what determines whether new varieties have traits conducive to poverty reduction who owns the research or what crop science is

not measuring sustainable value at all a response to kuosmanen and kuosmanen abstract in their article in this issue of ecological economics kuosmanen and kuosmanen kuosmanen t and kuosmanen n this issue how not to measure sustainable value and how one might ecological economics aim to criticise the measurement of sustainable value as proposed in our previous research by adopting a production perspective and based on a productive efficiency analysis they claim that the proposed way of measuring sustainable value represents an invalid simplification that rests on restrictive and unrealistic assumptions our response is to show that their argument rests on a fundamental misspecification of the sustainable value approach we identify three conceptual misfits a mismatch in the perspective of the analysis a misspecification of opportunity costs and the irrelevance of production functions ultimately kuosmanen and kuosmanen s train of thought rests entirely within the realm of productive efficiency analysis whereas sustainable value builds on the foundations of financial economics and consequently adopts a macro rather than a firm perspective it is thus not surprising that the findings of kuosmanen and kuosmanen appear to contradict the sustainable value approach however this is due to their fundamental misspecification of the sustainable value approach as a result rather than providing novel insights into how sustainable value might be measured in a better way they do not measure sustainable value at all

science technology and regional economic development review and prospects abstract this paper reviews the literature on the location and regional effects of science and technology st these pools of mobile workers are most attracted to large urban areas in only some of these areas however does the spin off process result in the generation of new technology based firms the availability of local venture capital appears to be the principal influence on this variation government policy regarding science and technology has impacts on regions by contributing to the agglomeration of r d government policy also often fails to recognize that s t policy and industrial policy have regional effects that may be long term in nature and most detrimental to those regions whose economies are least competitive finally some priorities for future research on innovation in a regional setting are identified

identifying spatial efficiency equity tradeoffs in territorial development policies evidence from uganda abstractwe contribute to the debate on the spatial allocation of infrastructure investments by examining where these investments generate the highest economic return spatial efficiency and identifying trade offs when infrastructure coverage is made more equitable across regions spatial equity we estimate models of firm location choice in uganda drawing on insights from the new economic geography literature the main findings show that manufacturing firms gain from being in areas that offer a diverse mix of economic activities public infrastructure investments in other locations are likely to attract fewer private investors and will pose a spatial efficiency equity trade off

electoral accountability and corruption evidence from the audits of local governments we show that political institutions affect corruption levels we use audit reports in brazil to construct new measures of political cor ruption in local governments and test whether electoral account ability affects the corruption practices of incumbent politicians we find significantly less corruption in municipalities where mayors can get reelected mayors with reelection incentives misappropriate 27 percent fewer resources than mayors without reelection incentives these effects are more pronounced among municipalities with less access to information and where the likelihood of judicial punish ment is lower overall our findings suggest that electoral rules that enhance political accountability play a crucial role in constraining politician s corrupt behavior jel d72 k42 017

does corporate social responsibility make over educated workers more productive this article provides first evidence on whether corporate social responsibility csr influences the productivity effects of over education by relying on detailed belgian linked employer employee panel data covering the period 1999 2010 our empirical results exhibit a positive and significant impact of over education on firm productivity moreover they suggest that the effect of over education is positively enhanced when the firm implements a csr process especially when it aims to have i a good match between job requirements and workers educational level ii a diverse workforce in terms of gender and age and iii a long term relationship with its workers when focussing on required education and over education the results suggest that csr besides representing an innovative and proactive approach for the firms stakeholders may also be beneficial for the firm itself through a bigger increase in productivity for each additional year of required education or over education

technology transfer and public policy a review of research and theory abstract my purpose is to review synthesize and criticize the voluminous multidisciplinary literature on technology transfer to reduce the literature to manageable proportions i focus chiefly not exclusively on recent literature on domestic technology transfer from universities and government laboratories i begin by examining a set of fundamental conceptual issues especially the ways in which the analytical ambiguities surrounding technology transfer concepts affect research and theory my literature review follows and i emphasize technology transfer s impact and effectiveness i employ a contingent effectiveness model of technology transfer to organize the literature as the model s name implies it assumes that technology effectiveness can take a variety of forms in addition to examining the more traditional effectiveness criteria those rooted in market impacts the model considers a number of alternative effectiveness criteria including political effectiveness capacity building

can microfinance reach the poorest evidence from a community managed microfinance intervention summary reaching the poorest is an important objective in many development interventions and microfinance is no exception we review performance indicators for effectiveness of targeting described in the literature and suggest a new metric in order to account for extent and severity of poverty as well as the income distribution among the poor when applying this to a panel dataset from a community managed microfinance intervention in northern malawi we find regressive targeting participants are less poor than the general population in the area in addition we provide suggestions as to when and why the poor exit the project

crime and local inequality in south africa the authors examine the effects of local inequality on property and violent crime in south africa their findings are consistent with economic theories relating inequality to property crime and also with sociological theories that imply that inequality leads to crime in general burglary rates are 20 30 percent higher in police station jurisdictions that are the wealthiest among their neighbors suggesting that criminals travel to neighborhoods where the expected returns from burglary are highest the authors do not find evidence that inequality between racial groups fosters interpersonal conflict at the local level

an activity analysis model of the environmental performance of firms application to fossil fuel fired electric utilities the productivity of firms when some outputs pollution are undesirable has been studied in the literature for some time in this paper we introduce an environmental performance indicator based on the decomposition of overall factor productivity into a pollution index and an input output efficiency index this indicator is compared to the more conventional jaggi and freedman 1992 model results are given for illustrative purposes using data from u s fossil fuel fired electric utilities the rankings of the utilities obtained with the two models show significant divergence which is due to the different ways in which the undesirable outputs are dealt with as well as due to the different possible tradeoffs between the pollutants released into the atmosphere and the resources used as inputs

how not to measure sustainable value and how one might abstract sustainability is a complex multidimensional concept that entails economic environmental and social aspects the sustainable value sv method developed by f figge and t hahn ecol econ 48 2004 173 187 is one of the most promising attempts to measure sustainability performance of firms sv measures corporate contributions to sustainability by valuing resource use based on the opportunity cost which must be estimated this paper critically examines figge and hahn s estimator for opportunity cost and shows that the proposed estimator rests on a number of strong unrealistic assumptions evidence from monte carlo simulations conducted by authors shows that the proposed estimator performs very poorly even under ideal conditions having identified shortcomings in the sv method we review some econometric approaches with a proven statistical foundation which might be usefully applied in the present context

justifying the incorporation of the materials balance principle into frontier based eco efficiency models frontier based models are an alternative to traditional eco efficiency ratio indicators this paper considers two different types environmentally adjusted production efficiency models and frontier eco efficiency models and tries to find justification for incorporating the materials balance principle mbp in them similar importance is attached to the economic and environmental outcomes of a production process like economic outcomes can be derived from inputs and outputs and respective prices some cases allow for deriving environmental outcomes from the production function with the mbp after an overview of attempts to incorporate environmental issues in production efficiency models and some reflections why mbp has been neglected in environmental economics and production efficiency analysis the paper gives basic principles to incorporate the mbp in conventional production efficiency methods and shows how this adjustment leads to a more diversified diagnosis of eco efficiency finally potentialities and bottlenecks are discussed exploiting the mbp in production efficiency and eco efficiency analysis will facilitate more pro active eco efficiency research

towards indicators of sustainable development for firms a productive efficiency perspective sustainable development can be reflected by various economic social and environmental factors that are closely interconnected with each other and with the additional dimension of time which stresses the long term perspective of several factors due to their central role in human activities and development firms should play an important part in the attainment of sustainability goals the purpose of this paper is to contribute to the methodology of indicators that allow for the assessment of business participation into sustainable development a fundamental standpoint adopted is to view economic social and environmental efficiency as a necessary but not sufficient step towards sustainability to work out indicators we build on both the concepts of cost benefit analysis and the principles of productive efficiency we assume that we have observations on economic social and environmental factors for a set of decision making units dmus e g firms in an industrial sub sector the efficiency of each dmu is computed from a set of observed data using mathematical programming techniques resulting in dmus that are efficient and define the efficiency frontier among the set of dmus and dmus that are inefficient to cope with the multidimensionality of sustainable development it is important not to base decisions on one unique aggregate sustainability indicator instead it is suggested to develop two or three partial indicators that stress different aspects of the problem the proposed indicators could be used as an aid to detect so called factors of unsustainability and hence to provide for recommendations as to the regulations and incentives or managerial practices that will contribute to overall sustainability c 1999 elsevier science b v all rights reserved
