the political economy of agriculture for development today the small versus large scale debate revisited the role of agriculture in economic development and the development politics of promoting smallholder versus large scale agriculture have both been at the center of a long lasting and controversial debate using an innovative methodology which combines a value chain approach with input output analysis the growth multipliers and productivity of both farm types in guatemala are analyzed results show that smallholder agriculture has the same potential to stimulate output growth as large scale agriculture smallholder value chains include mainly informal sectors and create more jobs than commercial agriculture therefore a reorientation of agricultural and land policies toward small scale food producers and within a comprehensive policy of integrated rural development is not only necessary in terms of social equity but also for boosting economic development

how general are time preferences eliciting good specific discount rates abstract this paper tests the commonly used assumption that people apply a single discount rate to the utility from different sources of consumption using survey data from uganda with both hypothetical and incentivized choices over different goods we elicit time preferences from about 2400 subjects we reject the null of equal discount rates across goods the average person in our sample is more impatient about sugar meat and starchy plantains than about money and a list of other goods we review the assumptions to recover discount rates from experimental choices for the case of good specific discounting consistently with the theoretical framework we find convergence in discount rates across goods for two groups expected to engage in or think about arbitraging the rewards traders and individuals with large quantities of the good at home as an application we evaluate empirically the conditions under which good specific discounting could predict a low asset poverty trap

life cycle consumption and hyperbolic discount functions abstract studies of animal and human behavior suggest that discount functions are approximately hyperbolic ainslie picoeconomics 1992 hyperbolic models explain a wide range of empirical anomalies including 1 missing precautionary savings effects 2 incongruence between the elasticity of intertemporal substitution and the inverse of the coefficient of relative risk aversion 3 consumption discontinuities at retirement 4 variation in patience over the life cycle 5 consumer self reports of undersaving 6 disproportionate retirement accumulation in illiquid assets 7 asset specific marginal propensities to consume and 8 declining national savings rates in developed countries hyperbolic models also provide a new framework for analyzing the welfare gains that come from pro saving policies like social security and tax deferred retirement accounts

ethical investment processes and outcomes there is a growing body of literature on ethical or socially responsible investment across a range of disciplines this paper highlights the key themes in the field and identifies some of the major theoretical and practical challenges facing both scholars and practitioners one of these challenges is understanding better the complexity of the relationship between such investment practices and corporate behaviour noting that ethical investment is seldom characterised by agreement about what it actully constitutes and that much of the extant research focuses on a narrow set of issues the paper argues that there are benefits associated with examining ethical investment as a process

agriculture led growth foodgrains versus export crops in madagascar abstract this article compares the growth generating power of alternative agricultural development strategies in madagascar projections from a semi input output model and a recently developed social accounting matrix suggest that both paddy and export crops stimulate strong linkages with other sectors of the malagasy economy but since paddy output can be increased at lower cost investment in rehabilitating small irrigated rice perimeters generates 40 to 100 more gdp than a comparable investment in coffee production paddy also generates greater employment and a more equitable income distribution

non agricultural earnings in peri urban areas of tanzania evidence from household survey data abstract this study draws on purposive survey data of approximately 600 households in peri urban tanzania to describe the degree and nature of non farm diversification in these settings with the exception of relatively dynamic cities such as dar es salaam and arusha overall non farm incomes shares are not unambiguously higher than in rural areas as a whole non farm income shares rise sharply and monotonically with quintiles defined in terms of per capita food consumption in that sense the sector appears to offer an important route out of poverty the evidence suggests that education and access to infrastructure are important determinants of non farm incomes in peri urban areas women appear to be poorly placed vis a vis the non farm sector even after controlling for education age and other characteristics kinship and tribal affinities and time devoted to communal activities appear to deter entrepreneurial activity and non farm employment but trust in officials and public servants and strong heterogeneous village associations are important in stimulating non farm activity

the financial performance of a socially responsible investment over time and a possible link with corporate social responsibility this paper empirically examines the financial performance of a uk unit trust that was initially conventional and later adopted socially responsible investment sri principles ethical investment principles comparison is made with three similar conventional funds whose investment objectives remained unchanged analysis techniques employed in previous studies find similar results mean risk adjusted performance is unchanged by the switch to sri with no evidence of over or under performance relative to the benchmark market index by any of the four funds more interestingly changes in variability of returns over time are also modelled using generalised autoregressive conditional heteroscedasticity models not previously applied to sri funds so far as is known results show a temporary increase in variability of returns followed by a return to previous levels after around 4 years evidence shows the increased variability to be associated with the adoption of sri rather than with a change in fund management possible explanations for the subsequent reduction in variability include the spread of corporate social responsibility activities by firms and learning by fund managers in addition to reporting on a previously unobserved phenomenon this paper raises questions for further research

socially responsible investing an investor perspective given the growing importance of socially responsible investing sri it is surprising that there is no consensus of what the term sri means to an investor further most studies of this question rely solely on the views of investors who already invest in sri funds our study surveys a unique pool of approximately 5 000 investors that contains both investors who have used sri criteria in investment decisions and those who have not and involves a broad array of criteria associated with sr investing our findings offer new insight into the sri debate for both sets of investors environmental and sustainability issues dominate as the major category associated with sr investing we find strong agreement in the ranking of the relative importance of various sri factors despite differences between these two groups in their opinion of their overall importance we also find that investors prefer to consider the sri question in more holistic terms rather than using the exclusionary format favored by most sri funds investors seem to prefer to reward firms who display overall positive social behavior rather than to exclude firms on the basis of certain products or practices these findings can help providers of sr investment vehicles to improve the sri products that they offer to the general investor thus both encouraging the initial adoption of sr criteria by investors and increasing overall investment in sr choices

subsistence response to market shocks microeconomic models posit that transaction costs isolate subsistence producers from output market shocks we integrate microeconomic models of many heterogeneous households into a general equilibrium model and show that supply on subsistence farms may respond in apparently perverse ways to changes in output market prices price shocks in markets for staple goods are transmitted to subsistence producers through interactions in factor markets in the case presented a decrease in the market price of maize reduces wages and land rents stimulating maize production by subsistence households however real incomes of subsistence households fall

subjective discounting in an exchange economy this paper describes the equilibrium of a discrete time exchange economy in which consumers with arbitrary subjective discount factors and homothetic period utility functions follow linear markov consumption and portfolio strategies explicit expressions are given for state prices and consumption wealth ratios we provide an analytically convenient continuous time approximation and show how subjective rates of time preference affect risk free rates but not instantaneous risk return trade offs hyperbolic discount factors can be a source of return volatility but they cannot be used to address asset pricing puzzles related to high frequency sharpe ratios

measuring investors socially responsible preferences in mutual funds the aim of this study is to analyze investor behavior towards socially responsible mutual funds the analysis is based on an experimental study where a sample of individuals takes investment decisions under different parameters of information about the investment alternatives and expected returns in the experiment each participant decides how to distribute an investment budget between two funds returns on which are uncertain and change over time two treatments are conducted each providing a different degree of information on the socially responsible sr character of one of the two investment alternatives the results obtained suggest that although individuals criteria for investment are essentially guided by returns and diversification participants invest significantly more in a fund when they are explicitly informed about its sr nature in particular participants who declare being concerned about sr actually invest significantly more in the sr alternative furthermore the level of sr faithfulness among a small group of investors is such that they invest the main share of their budget in the sr fund even when the return differential is highly unfavorable providing clear information about the sr characteristics of an investment is crucial to help investors express their preferences

a decade s debate on the nexus between corporate social and corporate financial performance a critical review of empirical studies 2002 2011 abstract theoretical discussions and empirical studies on the nexus between corporate social responsibility corporate social performance and corporate financial performance have never ceased since the origin of the concepts the development trajectories of such studies should be articulated with a view to informing practical corporate social responsibility applications and theoretical studies in the future this paper presents a critical review of relevant empirical research articles on the nexus between corporate social performance and corporate financial performance published during the ten year period from 2002 to 2011 using mixed methods of content analyses and statistical analyses the paper reviews 84 empirical studies of this kind published during the period the results indicate that despite the enormous amount of previous studies the corporate social performance and corporate financial performance nexus is a line of inquiry that remains inconclusive the pattern of corporate social performance corporate financial performance relationship research in the decade examined has shifted towards exploring the linkages between specific aspects of the two constructs the positive relationships between these specific aspects in dual directions are confirmed by most of the studies examined in this paper the paper also examines the impact of time and space change on the corporate social performance corporate financial performance nexus the findings show that researchers have gradually recognized that the relationship is not static but changes over time furthermore the paper finds that corporate social responsibility has been increasingly debated in developing countries and in specified industrial settings the review concludes that to explore the corporate social performance corporate financial performance nexus by contextualizing it in a specified community and or examine its dynamics is a promising research area that can yield significant academic and practical values

a non unitary discount rate model we develop a simple macroeconomic model in which agents discount their utility from consumption and the utility from leisure at different rates under this setting time inconsistency emerges for the preferences of agents moreover the time inconsistency problem generates two types of inefficiencies intratemporal and intertemporal we examine the welfare effects of savings subsidy and consumption tax the effects of taxation in our model are quite different from those in the standard model if the discount rate for consumption is higher lower than that for leisure today s self cares less more about the consumption of the future selves than the leisure of the future selves depressing stimulating the consumption of future selves improves the utility of today s self hence a positive negative consumption tax rate improves the utility level of all selves

regional growth linkages from agriculture pioneering research on downstream linkages from agriculture is said to demonstrate that consumption links rather than production links are the main source of indrect growth effects that these consumption links take the form of labour intensive goods and services produced locally and that the largest farm enterprises are most locally multiplicative of activities mopping up surplus rural labour this article has two purposes first the methodologies assumptions and data base for the quantification of the local and non local regional multiplier effects from agricultural development are examined second the contradictory interpretations for agricultural policy which have arisen from these exercises of quantification are discussed and an attempt made to explain their bases

how can safety nets contribute to economic growth the paper provides an up to date and selective review of the literature on how social safety nets contribute to growth the evidence is carefully chosen to show how safety nets have the potential to overcome constraints on growth linked to market failures and is organized into 4 distinct pathways i encouraging asset accumulation by changing incentives and by addressing imperfections in financial markets caused by constraints in obtaining credit and from information asymmetries overcoming such failures helps households to invest into their human capital or productive assets ii failures in insurance markets especially in low income setting safety nets are assisting in managing risk both ex post and ex ante iii safety nets are overcoming failure to create assets and other local economy complementary factors to household level investments iv safety nets are shown to relax political constraints on policy safety nets have a dual objective of directly alleviating poverty through transfers to the poor and of triggering higher growth for the poor however the trade off between the dual objectives of equity and growth is not eliminated by the potential for productive safety nets this remains critical for designing social policies

pairs trading the case of norwegian seafood companies abstractin this article i investigate the performance of a pairs trading strategy on 18 seafood company stocks traded in the norwegian consumer goods sector on the oslo stock exchange i apply both high frequency and daily data from january 2005 to december 2014 i use two approaches a distance approach and a cointegration approach and compare the results for both the distance and the cointegration approaches nonconvergence of the pairs is high which may indicate that more fundamental information about the companies traded should be accounted for none of the strategies evaluated had significant profits after accounting for transaction costs it therefore remains unclear which approach is best suited for pairs selection using high frequency data yielded empirical distributions that were symmetrical and had a lower degree of leptokurtosis compared to the daily data

modeling agricultural growth multipliers agriculture s potential as an engine of third world growth depends in large part on the size of the production and consumption linkages it stimulates in rural regions current estimates of agricultural growth multipliers within rural regions vary widely not only because economic structures differ across regions but also because the array of fixed price models most commonly used embody widely differing basic assumptions among fixed price models the semi input output formulation projects the most plausible multipliers but even they overstate the magnitude of growth multipliers by 10 to 25 according to the price endogenous model developed here

the impact of environmental policies on household incomes for different socio economic classes the case of air pollutants in indonesia abstract with outdoor air pollutants in indonesia as a case study this paper expands a social accounting matrix to include the link from the economy to the environment as well as the link from the environment to the economy this paper explores the relationship between production activities pollution and human health problems it utilizes the constrained fixed price multipliers method to analyze the impact of policies designed to reduce the amount of pollutants in the air on household incomes for different socio economic classes in indonesia the results show that if policies designed to reduce the amount of pollutants in the air do not decrease the output of production sectors then the policies also improve income distribution

the effect of green investment on corporate behavior this paper explores the effect of exclusionary ethical investing on corporate behavior in a risk averse equilibrium setting while arguments exist that ethical investing can influence a firm s cost of capital and so affect investment no equilibrium model has been presented to do so we show that exclusionary ethical investing leads to polluting firms being held by fewer investors since green investors eschew polluting firms stock this lack of risk sharing among non green investors leads to lower stock prices for polluting firms thus raising their cost of capital if the higher cost of capital more than overcomes a cost of reforming i e a polluting firm cleaning up its activities then polluting firms will become socially responsible because of exclusionary ethical investing a key determinant of the incentive for polluting firms to reform is the fraction of funds controlled by green investors in our model empirically reasonable parameter estimates indicate that more than 20 green investors are required to induce any polluting firmss to reform existing empirical evidence indicates that at most 10 of funds are invested by green investors

increasing returns and animal spirits the purpose of this note is to simply point out that the multiplicity intrinsic of course to the presence of non convexities characterizes the models of growth with external increasing returns which have been studied recently and more importantly to show that the many competitive equilibria which often arise in those models can be interpreted as animal spirits equilibria that is equilibria indexed by the consumers optimism or pessimism this multiplicity of competitive equilibrium paths can be viewed as providing a new foundation upon which to build a theory of self fulfilling prophecies one which relies solely on the existence of external effects and does not rest on the overlapping generation structure or on back ward bending offer curves the conclusion that multiple animal spirits competitive equilibria are likely to arise in a model of external increasing returns would survive the generalization of the framework used in this paper to many period environments be they overlapping generation or representative agent infinite horizon structures this abstract was borrowed from another version of this item

understanding sustainability innovations through positive ethical networks in this paper a positive organizational ethics poe based framework is informed by the microfinance and socially responsible investing movements to capture the process of sustainable financial innovations both of these movements are uniquely characterized by the formation of positive ethical networks pens to develop sustainability innovations in response to external crises the crisis pen innovation framework proposed makes four contributions to the poe literature 1 positions corporate sustainability through a poe lens 2 formalizes the pen construction through poe theory 3 proposes pens are mobilized to respond to external crises and 4 demonstrates how pens facilitate sustainability innovations the theoretical framework is tested using theory guided process tracing in the sustainable banking sector to understand how sustainability innovations were realized the findings are consistent with the crisis pen innovation framework proposed

agriculture and economic growth in ethiopia growth multipliers from a four sector simulation model abstract agriculture accounts for over half of ethiopian gdp yet the case for agriculture as a focus of economic growth strategies must rely on identifying a set of intersectoral linkages through which agricultural growth contributes to the growth of non agriculture in the ethiopian economy this article develops a four sector numerical simulation model of economic growth in ethiopia which permits the calculation of macroeconomic growth multipliers resulting from income shocks to agriculture services modern industry and traditional industry the resulting growth multipliers are 1 54 for agriculture 1 80 for services 1 34 for modern industry and 1 22 for traditional industry these results depict an economy in which intersectoral linkages operate on a highly uneven basis these limits are reflected in the wide disparity between sectoral growth multipliers and by substantial differences in the patterns of their decomposition the policy relevance of these findings relate in part to the distributional implications of growth in particular sectors poverty in ethiopia is disproportionately rural an income shock to agriculture is clearly the most progressive choice indicating the need to highlight agricultural development in growth strategies for ethiopia yet the simulation results further indicate that doing so imposes relatively little trade off against total benefit while a 1 service sector income shock generates 0 80 in indirect benefits a 1 agricultural income shock still generates 0 54 in indirect gains a somewhat smaller benefit but one likely to make the greatest possible impact on poverty reduction

do socially responsible fund managers really invest differently to date research into socially responsible investment sri and in particular the socially responsible investment funds industry has focused on whether investing in sri assets has any differential impact on investor returns prior findings generally suggest that on a risk adjusted basis there is no difference in performance between sri and conventional funds this result has led to questions about whether sri funds are really any different from conventional funds this paper examines whether the portfolio allocation across industry sectors and the stock picking ability of sri managers are different when compared to conventional fund managers the study finds that sri funds exhibit different industry betas consistent with different portfolio positions but that these differences vary from year to year it is also found that there is little difference in stock picking ability between the two groups of fund managers

agriculture reform and food crisis in syria impacts on poverty and inequality abstract the paper pursues a twofold objective from a methodological viewpoint it shows how to carry out an impacts evaluation of exogenous shocks on poverty and inequality in a context characterised by out of equilibrium poorly adjusting markets as it is the case in many developing countries using a social accounting matrix framework from an empirical viewpoint it provides an assessment of how the cereal price spikes of 2007 2008 and the global recession of 2008 2009 have impacted the welfare of syrian households and how did they compound with the on going agricultural sector liberalisation implemented by the government of syria since mid 1990s this will contribute to shed some lights on the economic background behind the spreading of unrest across the country over the last couple of years or so the results show that liberalisation impacts are very different and largely affected by the adopted budget closure rules while reforms aiming at reducing agricultural market distortions such as production subsidies and price support for strategic crops could generally have a positive effect on growth poverty and inequality the elimination of food security interventions such as food stamp schemes determines an adverse distributional impact against rural household and an increase of poverty the recent macroeconomic shocks food price crisis and the global recession determined a generalised poverty increase and showed an income distribution bias against rural households three fundamental policy implications can be drawn by this study first the liberalisation of agricultural sector shows a significant growth potential and is likely to determine positive effects on poverty through a generalised increase of incomes as well as public budget savings that could be used for pursuing other policy goals second in the short run there is a structural trade off between equity improvements and poverty alleviation the policy options that will more likely reduce absolute poverty show undesirable distributive biases both on overall inequality and on rural households vis a vis urban households third the reform should include a careful design of the use of budget savings mainly to address equity goals that are likely to be generated in the short run by liberalisation

political feasibility of structural adjustment in africa an application of sam mixed multipliers abstract the implementation of structural adjustment programs saps has often been undermined by opposition from politically powerful groups who are favored by existing policies to assess the political sustainability of saps this paper uses social accounting matrices for three african countries to model the income effects of stylized saps on different socioeconomic groups the analysis reveals wide variation in the likelihood for typical saps to be acceptable to political elites while generating growth in the rest of the economy the presence of a rural elite or strong farm nonfarm linkages can enhance the political sustainability of saps

district level economic linkages in kenya evidence based on a small regional social accounting matrix abstract this paper explores the nature and extent of the economic linkages in a small regional economy defined by a market center and its hinterland in kenya the analysis is based on a set of income and employment multipliers derived from a social accounting matrix estimated for the region issues considered include the impact of production activities on regional value added and employment the influence of sectoral production on the level of household income and the impact of household expenditure on regional value added and the relative significance of production and consumption linkages in terms of stimulating aggregate income the above questions are examined under the assumption of complete excess capacity in regional production and under the assumption of supply constraints in agriculture the usefulness of the analysis for district level economic planning is demonstrated

deal structuring in philanthropic venture capital investments financing instrument valuation and covenants philanthropic venture capital phvc is a financing option available for social enterprises that like traditional venture capital provides capital and value added services to portfolio organizations differently from venture capital phvc has an ethical dimension as it aims at maximizing the social return on the investment this article examines the deal structuring phase of phvc investments in terms of instrument used from equity to grant valuation and covenants included in the contractual agreement by content analyzing a set of semi structured interviews and thereafter surveying the entire population of phvc funds that are active in europe and in the united states findings indicate that the non distribution constraint holding for non profit social enterprises is an effective tool to align the interests of both investor and investee this makes the investor behaving as a steward rather than as a principal conversely while backing non profit social ventures philanthropic venture capitalists structure their deal similarly as traditional venture capital as the absence of the non distribution constraint makes such investments subject to moral hazard risk both in terms of perks and stealing and social impact focus

the message and methods of ethical investment abstract this paper examines a high profile and often provocative segment of the financial industry that of ethical or socially responsible investment by offering an ethical or sustainable product which has the potential to influence so many stakeholders the financial industry is in a unique position to guide change towards corporate sustainability however what message is ethical investment really giving to companies and the financial industry are ethical investors and their rating agencies capable of effectively influencing corporations towards more sustainable patterns of production and consumption and are their approaches consistent with the principles of cleaner production this paper first gives an overview some of the definitions ethical investment and the scale of activities under this umbrella term then the actual screening methods and their application is examined a typology of the different ethical mutual funds is given and two cases of ethical funds are described robur s environmental fund and sustainable asset management s sustainability rating tool each are analysed in terms of their potential to either reveal or conceal cleaner production innovations by the firms they assess in order to ascertain where ethical investment might lead companies the effects of ethical investment on companies and back on the asset management companies themselves is explored a reflexive model of corporate and finance sector learning based on the ethical screens is proposed

the rural non farm sector issues and evidence from developing countries abstract the rural non farm sector has traditionally been viewed as a low productivity sector which produces low quality goods it is often expected to wither away as a country develops recent years have seen a shift away from this position towards recognition that the rural non farm sector can and often does contribute to economic growth rural employment poverty reduction and a more spatially balanced population distribution this paper reviews the literature on the conceptual and empirical underpinnings of this more recent perspective focussing on the experience in developing countries the paper documents the size and heterogeneity of the sector pointing to evidence that in many countries the sector is expanding rather than declining the issues associated with measuring the sector s economic contribution are discussed followed by empirical assessments for several countries and regions the distributional impact of non farm earnings is examined and it is found that a pro poor impact while by no means inevitable can be considerable the sector s trajectory over time in different settings is reviewed and the scope for and experience of various policy interventions is discussed

the transmission of production fluctuations and technical change in a village economy a social accounting matrix approach rural poverty in india remains a pervasive and pressing problem of development despite the favorable performance of agricultural production which has nearly doubled in the last 2 decades 1 defining the poverty line as the level of income that permits an intake of 2 250 calories per day the incidence of poverty was 39 in the late nineteenfifties two decades later the latest available estimates for 1977 78 show that 39 of the population is still below the poverty line 2 because the increase in agricultural production is concentrated in areas with irrigation or assured rainfall much of the poverty is located in the unirrigated semi arid regions of irregular rainfall and it remains an important social issue the apparent failure of economic growth per se to decrease the incidence of poverty among other reasons led policymakers in india as elsewhere to formulate in the mid seventies specific antipoverty programs that focused on creating employment and production assets for the poor the search for solutions to the problem of rural poverty requires both a better understanding of its dynamics and of the effectiveness and limitations of these and other programs this article a case study of a village is a step in this direction it presents simulations of the impact of weather induced fluctuations in production and of the process of investment and accumulation in the village which reveal the most vulnerable groups in need of compensatory programs it also shows the important welfare effects that investment programs can have on the village economy any study of rural poverty in india must contend with the fact that it is not a homogeneous phenomenon in addition to the geographical variation in its incidence and causes rural poverty is also socially highly differentiated even in a small geographical region such as a village systematic differences arise between groups of poor house

equilibrium welfare and government policy with quasi geometric discounting abstract we consider a representative agent equilibrium model where the consumer has quasi geometric discounting and cannot commit to future actions we restrict attention to a parametric class for preferences and technology and solve for time consistent competitive equilibria globally and explicitly we then characterize the welfare properties of competitive equilibria and compare them to that of a planning problem the planner is a consumer representative who without commitment but in a time consistent way maximizes his or her present value utility subject to resource constraints the competitive equilibrium results in strictly higher welfare than the planning problem whenever the discounting is not geometric journal of economic literature classification numbers e21 e61 e91

the economy wide impact of controlling energy consumption in indonesia an analysis using a social accounting matrix framework escalating oil prices and the need to control carbon emissions sound the alarm for indonesia to reduce or be more efficient in its energy use instead of eliminating the fuel oil subsidy to promote better and more efficient use of energy the indonesian government seems to be more in favour of restricting energy use by for example requiring all hotels restaurants night clubs and other business activities to close down by 1 am societies need to understand the full consequences of adopting restricting energy use and more efficient energy use strategies toward their incomes this paper aims to analyse the impact on the economy of energy policies aiming to reduce and to improve the efficiency of energy use particularly on the income of various household groups this paper will first construct a social accounting matrix for indonesia with detailed energy sectors and second utilise various multiplier analyses to observe and understand the impact of these energy policies

a critical review of sustainable business indices and their impact most studies into the performance of socially responsible investment vehicles have focused on the performance of sustainable or socially responsible mutual funds this research has been complemented recently by a number of studies that have examined the performance of sustainable investment indices in both cases the majority of studies have concluded that the returns of socially responsible investment vehicles have either underperformed or failed to outperform comparable market indices although the impact of sustainable indices to date has been limited the recent launch of sustainable indices by dow jones and ftse suggests that more attention is being paid to the subject by financial markets investors and companies this development raises a number of important issues which are reviewed in this article a the performance of indices compared with their benchmark indices b the methodologies employed in compiling the indices and c the impact of the indices on companies and the investment community the article concludes with a number of suggestions for areas that merit future research

consumption savings decisions with quasi geometric discounting we study the consumption savings problem of an infinitely lived rational consumer who has time inconsistent preferences in the form of quasi geometric discounting the consumer operates a weakly concave production function and must simply divide current resources into current consumption and savings there is no uncertainty a solution to the consumer s problem is a subgame perfect equilibrium of a dynamic game between the consumer s successive selves we show that this game has a continuum of equilibria in stationary markov strategies not only is the stationary point of the consumer s asset holdings indeterminate but each stationary point has a continuum of dynamic paths converging to it the savings policy rules underlying these dynamic paths are step functions

agricultural growth linkages in guatemala new insights from a value chain approach the agricultural growth linkage debate substantiates that agriculture contributes to economic growth through its linkages to other sectors this paper contributes to the debate by combining a value chain approach with input output analysis results for guatemala show that the sectors linked to agriculture are predominantly informal sectors and that these sectors create less value added but more employment than formal sectors it is also demonstrated that forward linkages are more important than backward linkages in conclusion agricultural linkages to forward sectors have a high potential to generate employment and value added and therefore should be supported by development policies

the maturing of socially responsible investment a review of the developing link with corporate social responsibility this paper reviews the development of socially responsible investment sri over recent years and highlights the prospects for an increasingly strong connection with the practice of corporate social responsibility the paper argues that not only has sri grown significantly it has also matured in particular it has become an investment philosophy adopted by a growing proportion of large investment institutions this shift in sri from margin to mainstream and the position in which institutional investors find themselves is leading to a new form of sri shareholder pressure although this bears some resemblance to lobbying campaigns which might take advantage of shareholder rights we seek to distinguish it as an important phenomenon in its own right one to which corporate executives are likely to be paying increasing attention in the years to come we further argue that this approach potentially meets some of the earlier ethical criticisms of certain forms of sri but ironically probably owes its existence to those pioneering approaches we conclude with some suggestions for further research to inform discussion of the issues highlighted in the paper

discount rates inferred from decisions an experimental study two hundred and four students of economics and finance participated in an intertemporal choice experiment which manipulated three dimensions in a 4 4 4 factorial design scenario postponing a receipt postponing a payment expediting a receipt expediting a payment time delay 0 5 1 2 and 4 years and size of cashflow 40 200 1000 and 5000 individual discount rates were inferred from the responses and then used to test competitively four hypotheses regarding the behavior of discount rates the classical hypothesis asserting that the discount rate is uniform across scenarios time delays and sums of cashflow was flatly rejected a market segmentation approach was found lacking the results support an implicit risk hypothesis according to which delayed consequences are associated with an implicit risk value and an added compensation hypothesis which asserts that individuals require compensation for a change in their financial position

performance of ethical mutual funds in spain sacrifice or premium there is currently much debate in the economic literature about whether ethical investment involves a financial sacrifice or premium one of the most common methods of testing this compares the financial performance of ethical investment funds with that of other funds not considered socially responsible or ethical the majority of these research studies evaluate the performance of the ethical funds according to classic measures whereby different financial markets in different countries and for different periods of time serve as reference for evaluation the ultimate conclusion of all of these studies is that there are no significant differences between the performance results of one type of funds and the other in spain ethical investment funds are still an incipient sector of investment to date the spanish market has not been included in any type of analysis of these characteristics therefore the main objective of this article is to compare the financial performance of ethical investment funds to that of other funds in the spanish retail market we propose the aggregate type of analysis as the spanish ethical investment funds have experienced a weaker development in comparison to those of other developed countries in the first step we suggest the financial performance to be compared by style analysis since the asset distribution of the spanish social return investment sri funds differs from the european trend in particular we use the multifactor regression model with style benchmarks we found that their financial performance is in all cases superior or similar to that achieved by the rest of the funds in the second step to achieve a more robust and homogeneous comparison we used the bootstrap method comparing ethical and non ethical fund subsamples by homogeneous groups no significant differences between these two types of funds have been found thus if we assume the positive o neutral effect of ethical investment on investor utility in the retail spanish market the financial and social performance fsp of ethical funds will be in aggregate superior to the fsp achieved by conventional funds in conclusion the financial performance of ethical mutual funds in spain is no sacrifice

rational expectations business cycles in search equilibrium we examine the rational expectations equilibrium paths of the model of search and barter in diamond s aggregate demand management in search equilibrium for some initial positions there are two equilibrium paths converging to different steady states with the high activity path pareto dominating the low activity path with some parameters there is also a continuum of equilibrium paths converging to another steady state moreover there can be cycles that are equilibrium paths even though the environment is stationary

slow money in an age of fiduciary capitalism abstract in the era of fiduciary capitalism investors have begun fulfilling non financial goals in order to address the concerns of a broader range of stakeholders socially responsible investors who were part of fringe movements headed by non profit organizations have emerged as powerful fiduciaries with a strong focus on triple bottom line based outcomes the slow money movement which has been spear headed by non profits in the developed world places a strong emphasis on making capital circulate locally especially within agricultural communities slow money investors across the us some of whom are private investment funds and community development financial institutions are striving to generate triple bottom line based outcomes in our study we have discussed how the slow money movement mirrors fiduciary capitalism we have analyzed how slow money investors have expanded the scope of traditional fiduciary obligations five organizations in the us have participated in our research and we developed a seven point taxonomy of slow money to analyze our findings our findings revealed how slow money investors as fiduciary capitalists generate financial social and environmental returns by investing patient capital in agriculture and local enterprises

a model of imperfect competition with keynesian features the recent literature on the reappraisal of keynes has viewed keynesian equilibria as arising when prices are fixed and effective demands and supplies are equilibrated through the adjustment of quantities one problem with this approach is that it lacks a theory of price determination in particular of why prices are fixed in the present paper we show that a number of keynesian features arise in a model in which prices are fully flexible but where agents have some monopoly power one advantage of this approach is that it provides a theory of the determination of both prices and quantities
