wheat from chaff meta analysis as quantitative literature review abstract this paper presents and develops a quantitative method of literature reviewing and evaluating empirical research meta regression analysis or mra economics is theory driven yet we must learn empirically if economics is to advance mra offers a more objective statistical method to summarize our empirical knowledge and to explain the wide study to study variation in economic research mra is used to assess the evidence for ricardian equivalence and its findings are contrasted to those of conventional narrative review furthermore mra establishes a platform from which to distinguish genuine empirical effect from the exploitable specification error that infests applied econometrics

fdi and taxation a meta study despite the continuing political interest in the usefulness of tax competition and tax coordination as well as the wealth of theoretical analyses it still remains open whether or when tax competition is harmful moreover the influence of tax differentials on multinationals decisions is still insufficiently analyzed thus economists have increasingly resorted to empirical analysis in order to gain insights on the elasticity of fdi with respect to company taxation as a result the empirical literature on taxation and international capital flows has grown to a similar abundance during the last 25 years as the respective theoretical literature its heterogeneity leads to a rising need for concise reviews on the existing empirical evidence in this paper we extend former meta analyses on fdi and taxation in three ways first we add the most recent publications unconsidered in meta analyses up to date second we apply a different methodology by using a broad set of meta regression estimators and explicitly discuss which one is most suitable for application to our meta data third we address some important issues in research on fdi and taxation to the clarification of which meta analysis can make valuable contributions these issues are mainly the influence of variables which might moderate effects of tax differentials e g public spending the implications of using aggregate fdi data as opposed to firm level information on measured tax effects the implications of bilateral effective tax rates and the possible presence of publication bias in primary research

introduction imperfect information and rural credit markets puzzles and policy perspectives rural credit markets have been at the center of policy intervention in developing countries over the past forty years many governments supported by multilateral and bilateral aid agencies have devoted considerable resources to supplying cheap credit to farmers in a myriad of institutional settings the results of many of these interventions have been disappointing and one explanation for this must be that they were based on an inadequate understanding of the workings of rural credit markets the articles in this symposium issue are devoted to empirical and theoretical investigations of rural credit markets in the framework of the imperfect information paradigm the authors show how this framework is useful not only in explaining puzzling features of these markets but also in providing a policy perspective to assess the successes and failures of specific interventions

modeling determinants of poverty in mauritania abstract this paper presents a brief descriptive summary of poverty in mauritania as revealed by household survey data for 1990 and then uses regression analysis to study the determinants of living standards and hence poverty the latter is conducted at the level of broadly defined socioeconomic groups using an econometric technique which also models the selection of households into socioeconomic groups household characteristics are used as explanatory variables including demographic education and sector specific variables by controlling for many factors multivariate analysis enables a clearer understanding of the nature and determinants of poverty than can be obtained from examination of summary poverty indices

political risk institutions and foreign direct investment how do they relate in various european countries this paper examines theoretically and empirically the extent to which the decision by foreign firms to invest in a group of countries is influenced by economic factors as opposed to political risk and institutional performance we consider the importance of these factors as drivers of foreign direct investment fdi for 32 european countries subsequently divided into three pooled clusters by means of panel regression techniques in two specifications over the 1995 2008 period our results suggest that risk and institutional factors considered in both static and dynamic perspectives significantly influence the behaviour of investors policies and institutions that vary widely between countries modify their decision making so that the purely economic factors have different statistical significance and impacts on the intensity of fdi as was revealed by clustering countries into three groups according to levels of economic maturity additionally not all factors of risk have an identical impact on fdi decisions in particular groups of countries however we find that as measures of political risk monetary discipline low regulation effective government and good education prove to be highly significant for most country groupings all of these measures reduce political risk and positively affect the level of fdi this abstract was borrowed from another version of this item

aid and growth what meta analysis reveals abstract recent literature in the meta analysis category where results from a range of studies are brought together throws doubt on the ability of foreign aid to foster economic growth and development this article assesses what meta analysis has to contribute to the literature on the effectiveness of foreign aid in terms of growth impact we re examine key hypotheses and find that the effect of aid on growth is positive and statistically significant this significant effect is genuine and not an artefact of publication selection we also show why our results differ from those published elsewhere

producer cooperative resettlement projects in zimbabwe lessons from a failed agricultural development strategy abstract zimbabwe epitomizes the contradictions driving the failure of state directed agricultural development policies in its second decade of independence the government takes the credit for the country s agricultural and rural development success zimbabwe s green revolution record in africa is enviable yet this peasantry led success story is problematic it hides serious policy flaws in development strategy namely lack of performance and waste characterizing the model b producer cooperative resettlement projects individually and collectively the cooperatives the government s preferred mode of production are a complete failure lessons for development programs elsewhere and in emergent south africa in particular are clear the political economy of government assistance is not sufficient to produce agricultural surpluses and sustainable development the social economy of cooperation in production organization by africa s traditional farmers also does not necessarily translate into modern cooperatives as zimbabwe s policy makers assumed producer cooperatives are unproductive because of the prevailing organizational culture which enables leading members to seek individual self interest and private gain making it hard for the rank and file to cooperate and work for the common good

financial development and economic growth a meta analysis we analyze 1334 estimates from 67 studies that examine the effect of financial development on economic growth taken together the studies imply a positive and statistically significant effect but the individual estimates vary widely we find that both research design and heterogeneity in the underlying effect play a role in explaining the differences in results studies that do not address endogeneity tend to overstate the effect of finance on growth while the effect seems to be weaker in less developed countries the effect decreases worldwide after the 1980s our results also suggest that stock markets support faster economic growth than other financial intermediaries

private agri food standards implications for food policy and the agri food system abstract this paper provides a brief introduction to the evolution and nature of private food safety and quality standards highlighting the resultant impacts on the structure and modus operandi of supply chains for agricultural and food products and the challenges posed for processes of agricultural development it serves as an introduction to a series of papers that provide a comprehensive overview of the current state of knowledge regarding private food safety and quality standards in both an industrialised and developing country context in so doing it aims to provide a catalyst for further research on this rapidly evolving field of inquiry

the use and abuse of meta analysis in environmental and natural resource economics an assessment motivated by the 2006 report of a work group appointed by the environmental protection agency epa this paper examines the present state of meta analysis in environmental economics and offers recommendations for its future use to this end we summarize and assess 140 meta analyses from 125 published and unpublished studies covering 17 topical categories in environmental and resource economics first we provide several generic meta analysis models as reference points and discuss major estimation issues five econometric issues are identified as part of a complete analysis 1 sample selection criteria 2 basic data summary 3 primary data heterogeneity 4 heteroskedasticity and 5 non independence of multiple observations from primary studies second a tabular summary is presented for the 140 meta analyses with respect to estimation methods third a narrative summary is presented for 19 meta analyses including the three value of statistical life studies examined by the epa work group and one analysis from each of 16 other categories fourth we offer a set of best practice guidelines for future meta analyses in this and other areas of economics last the paper comments on the use of meta analytic methods for benefit transfers of environmental values

change of competition regime and regional innovative capacities evidence from dairy restructuring in france the aim of this article is to analyze how market actors and farmers in particular mobilize collective coordination capacities to face global changes market price or sectorial policies within different regional contexts a multi scale conceptual framework is proposed to analyze market functioning and transformation over time and space we extend commons and fligstein s work on market institutions to define the notion of competition regime as a combination of four market institutions that legitimizes competition strategies we also mobilize ostrom s work on common property rights regimes to show that a competition regime relies on the creation and management of two systems of common pool resources namely innovation capacity and reputation building this paper then shows the relevance of this framework through the case study of the current restructuring of dairy supply chains in mountainous areas in france it shows that market liberalization strongly destabilizes the regional competition regimes that were based on the appropriation of social rights inherent to the national public policies in the hybrid and specific competition regimes existing territorial coordination devices are not directly threatened and can support the development of new cooperative strategies in all cases with the development of a contractual economy farmers are incited to develop or to strengthen coordination devices to become effective market participants through the development of large territorial producers organizations capable of managing milk supply in volume and quality they would be able to take part in the management of the supply chains to do so the present paper suggests that farmers organizations need material and immaterial investments and assistance from regional public players to build new local collective capacities the competition regime framework is an asset for the design of such public supports in accordance with the principle of subsidiarity taking the regional specificity of the markets institutions and collective capacities into account

flexible production systems and local machine tool subcontracting electronics components transnationals in malaysia this paper examines the influence of flexible production systems on the development of local sourcing using information gathered on production relationships between firms it shows that the introduction of flexible production systems in electronics components transnationals in malaysia stimulated the growth of local machine tool firms a combination of market forces and cooperation strengthened subcontracting links between electronics components transnationals and local machine tool firms such that the latter experienced considerable technological broadening and deepening thereby transforming them from simple parts to high precision tooling and automation systems manufacturers copyright 1994 by oxford university press

financial services for microenterprises principles and institutions abstract this article argues for the use of a financial systems approach in the provision of financial services to the poor the experience of the last decade has produced a successful technology for credit delivery that utilizes sound financial principles as its basis that is understanding the needs of the client increasing efficiency by cutting administrative costs and using various techniques to motivate repayment savings receives equal emphasis as a financial service and several principles for its provision are discussed the institutional dimensions behind this approach focus on the need to achieve self sufficiency which the article frames as a four stage process finally the article outlines various factors related to creating financial institutions that reach the poor and the policy implications that these suggest

collective action initiatives to improve marketing performance lessons from farmer groups in tanzania this study aims to examine the extent to which certain characteristics and asset endowments of smallholder farmer groups facilitate collective action initiatives to improve group marketing performance this is approached through an evaluation of a government led programme in tanzania which is attempting to increase smallholder farmers incomes and food security through a market oriented intervention findings suggest that more mature groups with strong internal institutions functioning group activities and a good asset base of natural capital are more likely to improve their market situation gender composition of groups also affects group marketing performance as an enabling factor for male dominated groups structural social capital in the form of membership in other groups and ties to external service providers and cognitive social capital in the form of intra group trust and altruistic behaviour are not significant factors in a group s ability to improve its market situation

selling at the farmgate or traveling to market using detailed survey data from uganda this article examines whether coffee producers sell to itinerant traders or directly to markets where they can get a higher price but must incur a transport cost we find that selling to the market is more likely when the quantity sold is large and the market is close by wealthy farmers are less likely to sell to the market possibly because the shadow value of their time is higher but if they have a large quantity of coffee for sale they are more likely to sell it to the market they are also more likely to travel to a distant market these findings are consistent with their better ability to pay for public transportation we find no evidence that the decision to sell at the farmgate is driven by a self control motive

promoting the role of farmer based organizations for value chain integration the tension between a program s targeting and an organization s investment strategy we use new data on 500 farmer based organizations fbos in ghana and regression analysis to reveal determinants of collective investments and the case of the millennium development authority s mida agricultural program in ghana to demonstrate that development programs offering hard incentives may be counterproductive in promoting collective action we show that when a program sets criteria for participation and offers in cash and in kind support to selected fbos it may promote rent seeking and crowd out equity capital formation this is so because fbos may have formed for the sole purpose of benefitting from incentives offered by the program and thus lack an economic justification which is an important condition for progression through the cooperative life cycle further by setting stringent participation criteria the program may end up selecting younger organizations while it is the more consolidated organizations that are able to connect to business development services bds and engage in more offensive collective action

exploring double side selling in cooperatives case study of four coffee cooperatives in rwanda apart from the difficulty to attract new members leakage of sales outside the cooperative is a major challenge for the coffee cooperatives in rwanda local independent traders still constitute a major market for coffee producers yet cooperatives also accept the produce from non members and pay them the same price our objective in this paper is to analyse the importance of this phenomenon of double side selling we collected data from a sample of 170 coffee farmers we use a probit model to analyse characteristics linked to cooperative membership and to study double side selling we describe the trade relationships between farmers and the cooperative on the one hand and between farmers and traders on the other by the attributes of transaction costs involved in the trade of coffee membership characteristics include easy access to labour land tenure risk aversion and mutual trust between farmers and cooperatives management preference to sell to traders can be explained by the trust farmers seem to have in them after the repeated transactions in credit and basic consumption items and by long term relationships in the community

common property institutions and sustainable governance of resources abstract the literature on common property based resource management comprises many important studies that seek to specify the conditions under which groups of users will self organize and sustainably govern resources upon which they depend using three of the more comprehensive such studies and with an extensive review of writings on the commons this paper demonstrates that the enterprise of generating lists of conditions under which commons are governed sustainably is a flawed and impossibly costly research task for a way out the paper examines the relative merits of statistical comparative and case study approaches to studying the commons it ends with a plea for careful research design and sample selection construction of causal mechanisms and a shift toward comparative and statistical rather than single case analyses such steps are necessary for a coherent empirically relevant theory of the commons

picture this a simple graph that reveals much ado about research funnel graphs provide a simple yet highly effective means to identify key features of an empirical literature this paper illustrates the use of funnel graphs to detect publication selection bias identify the existence of genuine empirical effects and discover potential moderator variables that can help to explain the wide variation routinely found among reported research findings applications include union productivity effects water price elasticities common currency trade effects minimum wage employment effects efficiency wages and the price elasticity of prescription drugs

resource development and inequality in indigenous societies concern has been expressed both by indigenous people and by academic analysts that large scale resource development may sharpen inequality in what are relatively egalitarian indigenous societies much of the academic literature suggests that resource development does indeed have this effect but such claims are usually based on very limited empirical evidence in addition the literature is lacking in conceptual frameworks which allow the concept of inequality to be adequately specified take into account the quite different forms of income which resource development can generate explain rather than simply document specific changes in income distribution and on this basis provide grounds for policy prescription this article seeks to develop such a framework

linking smallholders to markets determinants and impacts of farmer collective action in kenya summary this article investigates determinants and impacts of cooperative organization using the example of smallholder banana farmers in kenya farmer groups are inclusive of the poor although wealthier households are more likely to join employing propensity score matching we find positive income effects for active group members yet price advantages of collective marketing are small and high value market potentials have not yet been tapped beyond prices farmer groups function as important catalysts for innovation adoption through promoting efficient information flows we discuss the conditions under which collective action is useful and through what mechanisms the potential benefits emerge

beyond publication bias abstract this review considers several meta regression and graphical methods that can differentiate genuine empirical effect from publication bias publication selection exists when editors reviewers or researchers have a preference for statistically significant results because all areas of empirical research are susceptible to publication selection any average or tally of significant insignificant studies is likely to be biased and potentially misleading meta regression analysis can see through the murk of random sampling error and selected misspecification bias to identify the underlying statistical structures that characterize genuine empirical effect meta significance testing and precision effect testing pet are offered as a means to identify empirical effect beyond publication bias and are applied to four areas of empirical economics research minimum wage effects union productivity effects price elasticities and tests of the natural rate hypothesis

did fdi really cause chinese economic growth a meta analysis summary foreign direct investment fdi has been linked to economic growth in a number of countries productivity spillovers at the firm level have been identified as a key element in the process by which fdi stimulates economic growth moreover there is evidence of fdi related productivity spillovers in china whether these spillovers have been of sufficient size to affect growth at the aggregate level however is an empirical question we apply meta analysis to the corresponding empirical literature to find an answer our main finding is that the effect of fdi on chinese economic growth is much smaller than one would expect from a naive aggregation of existing estimates publication bias and a profusion of estimates based on less preferred study and sample characteristics have served to inflate observed estimates once these effects are accounted for the estimated effect of fdi on chinese economic growth is reduced to statistical insignificance this suggests that the cause s of the chinese economic miracle likely lie elsewhere

path dependence in regional development persistence and change in three industrial clusters in santa catarina brazil abstract the concept of path dependence is useful to understand why economic actors who face a fundamental change in the overall incentive structure behave in a way that would appear irrational to the external observer industrial clusters in the southern brazilian state of santa catarina gave an impressive performance in the closed market of the past it was perfectly rational for individual firms to try to internalize as many activities as possible for various reasons thus emerged an extremely noncooperative business culture which does not change easily even under the new conditions of an opening market and increasing competitive pressure firms try to adjust to the new conditions based on their established practices yet the comparison between different clusters reveals that under certain conditions the behavior of firms can change profoundly toward cooperation and collective efficiency these conditions include an existential crisis the presence of change agents and the existence of organizations they can use and the existence of a role model that shows a possible alternative path for the adjustment process the most important changes are attempts to stimulate cooperation between firms and attempts to shape the supporting environment most changes occur inside the business community the political administrative system at the municipal and state levels is much more resistant to change

when and where does foreign direct investment generate positive spillovers a meta analysis local firms may attract productivity spillovers from foreign investors yet these vary with local firms awareness capability and motivation to react to foreign entry in consequence spillovers vary across countries at different levels of economic development we apply competitive dynamics theory to analyze these contextual moderators of spillovers and test hypotheses thus derived in a meta analysis of the empirical literature on spillovers our analysis suggests a curvilinear relationship between spillovers and the host country s level of development in terms of income institutional framework and human capital

finding default understanding the drivers of default on contracts with farmers organizations under the world food programme purchase for progress pilot during the past two decades food assistance policy has shifted toward local or regional food purchases and away from purchases from donor countries while most local and regional procurement occurs through hard tendering processes open to large scale firms and farms there is growing interest in identifying how and whether to procure from smallholder farmer organizations to date little is known about the drivers of successful contracting with farmers organizations fos we utilize data from the united nations world food programme purchase for progress pilot in three east african countries to predict defaults on contracts we examine four possible explanations country contexts fo characteristics prior experience with contracts and contract modalities and their relationship to local spot market prices the single most important predictor of default is the increase in market prices between contract approval and delivery yet while increases in market prices are linked to increases in default this relationship is decreasing in contract size indicating search costs associated with breaking contracts our findings yield both generalizable and context specific insights about whether and when procuring from smallholder farmers can be successfully integrated into the food assistance toolkit this article is protected by copyright all rights reserved

marketing cooperative vs commission agent the turkish dilemma on the modern fresh fruit and vegetable market in turkey the wholesale markets law was enacted in 1995 to facilitate small scale growers access to the fresh produce market cooperatives and commission agents have thus become the main marketing structures available to small scale fresh produce growers to supply supermarkets and comply with their new requirements in this paper we question the advantages and disadvantages that confront small farmers with respect to those marketing structures to allow for market matching or quality upgrading drawing on ownership and transaction cost arguments we use an analytical framework to identify and compare the costs of these marketing organizations based on data collected through a large number of interviews with stakeholders we show that commission agents and credit cooperatives tend to be more efficient than traditional cooperatives as regards sales performance and decision costs however the lack of apparent competition between commission agents does not allow for sufficient provision of incentives for producers to invest in high quality production consequently credit cooperatives are the only structure progressively turning to strategies of quality upgrading and supermarket supply the flipside of such strategies is that they may lead to the marginalization of small scale farmers

are all economic facts greatly exaggerated theory competition and selectivity there is growing concern and mounting evidence of selectivity in empirical economics most empirical economic literatures have a truncated distribution of results the aim of this paper is to explore the link between publication selectivity and theory contests this link is confirmed through the analysis of 87 distinct empirical economics literatures involving more than three and a half thousand separate empirical studies using objective measures of both selectivity and contests our meta meta analysis shows that publication selection is widespread but not universal it distorts scientific inference with potentially adverse effects on policy making but competition and debate between rival theories reduces this selectivity and thereby improves economic inference

natural resources and economic growth a meta analysis summary an important question in development studies is how natural resources richness affects long term economic growth no consensus answer however has yet emerged with approximately 40 of empirical papers finding a negative effect 40 finding no effect and 20 finding a positive effect does the literature taken together imply the existence of the so called natural resource curse in a quantitative survey of 605 estimates reported in 43 studies we find that overall support for the resource curse hypothesis is weak when potential publication bias and method heterogeneity are taken into account our results also suggest that four aspects of study design are especially effective in explaining the differences in results across studies 1 controlling for institutional quality 2 controlling for the level of investment activity 3 distinguishing between different types of natural resources and 4 differentiating between resource dependence and abundance

peasant household behaviour with missing markets some paradoxes explained a model of peasant household behavior under varying degrees of household specific food and labor market failures is constructed to show that these structural features can explain several well known patterns of peasant response which have often been attributed to peculiar motives presumed specific to peasants the model explains sluggish response to cash crops prices and high instability in perceived food and labor scarcities the key role of manufactured consumer goods prices in stimulating peasants effort in cash crops production the effectiveness of taxation as opposed to incentives in stimulating cash crops production and the key role of technological change in food production to enhance cash crop production results are obtained analytically in the case of one market failure and by numerical simulation with more than one

bank competition and financial stability much ado about nothing the theoretical literature gives conflicting predictions on how bank competition should affect financial stability and dozens of researchers have attempted to evaluate the relationship empirically we collect 598 estimates of the competition stability nexus reported in 31 studies and analyze the literature using meta analysis methods we control for 35 aspects of study design and employ bayesian model averaging to tackle the resulting model uncertainty our findings suggest that the definition of financial stability and bank competition used by researchers influences their results in a systematic way the choice of data estimation methodology and control variables also affects the reported coefficient we find evidence for moderate publication bias taken together the estimates reported in the literature suggest little interplay between competition and stability even when corrected for publication bias and potential misspecifications this abstract was borrowed from another version of this item

collective efficiency growth path for small scale industry this study is concerned with the growth of small local industry in developing countries and explores one particular route for understanding and fostering such growth it focuses on the clustering of firms and the competitive advantage which they derive from local external economies and joint action captured in the concept of collective efficiency following a conceptual discussion the article explores the economic and institutional conditions which enhance or hinder collective efficiency this includes a case study which suggests that responding to opportunity and crisis requires shifting from mere reliance on external economies to joint action and from ascribed to earned trust

contractual arrangements between farmer cooperatives and buyers in china the agrofood market in china is dominated by spot market exchanges of small farmers and various small traders with only minor penetration of the modern supply chain at the farmgate the emerging farmer professional cooperatives fpcs are expected to facilitate vertical coordination the overall goal of this study is to investigate the contractual arrangements between the fpcs and the buyers based on a national representative survey of 157 fpcs in china this study shows that 32 of fpcs introduced written contracts in the primary marketing channel contracts are more likely to be adopted in the livestock sector and are positively related to the scale of production while branding promotes contracts between fpcs and buyers public certification of quality and food safety often substitutes for contracts furthermore the membership heterogeneity of fpcs affects an fpc s decision to use contractual arrangements with the buyer

measuring intertemporal substitution the importance of method choices and selective reporting i examine 2 735 estimates of the elasticity of intertemporal substitution in consumption eis reported in 169 published studies the literature shows strong selective reporting researchers discard negative and insignicant estimates too often which pulls the mean estimate up by about 0 5 the reporting bias dwarfs the effects of methods with the exception of the choice between micro and macro data when i correct the mean for the bias for macro estimates i get zero even though the reported t statistics are on average two the corrected mean of micro estimates of the eis for asset holders is around 0 3 0 4 calibrations greater than 0 8 are inconsistent with the bulk of the empirical evidence jel e21 c83

producer relationships and local development in fresh fruit commodity chains an analysis of blueberry production in entre rios argentina craviotti c producer relationships and local development in fresh fruit commodity chains an analysis of blueberry production in entre rios argentina regional studies in current regional perspectives intangible capitals are considered critical assets of regional economies the aim of this article is to analyse the role of networks in the development of blueberry production in the province of entre rios nowadays the most important productive area of argentina it argues that although horizontal networks either private or public private were not particularly important for the emergence of blueberry production in the area they are needed in a situation where a redefinition of the agri food chain is at stake coordination and cooperation networks could help to sustain the continuity of production at the local level and to make local small scale producers viable in a global context craviotti c

survey article publication bias in the literature on foreign direct investment spillovers abstract in this article we conduct a large quantitative survey of the literature on horizontal and vertical spillovers from foreign direct investment fdi we create a unique database of spillover estimates for each country examined in the literature next we estimate the average effect corrected for publication selection bias the preferential selection of positive and significant estimates for publication our results suggest that an average reported estimate of backward spillovers is statistically significant publication selection is evident only among studies published in peer reviewed journals and only among the estimates that authors consider most important authors with small data sets engage in more publication selection the intensity of selection in the literature decreases over time which supports the economics research cycle hypothesis

how to promote clusters policy experiences from latin america abstract in this paper we propose to differentiate between three types of clusters when it comes to formulating cluster oriented policies in latin america survival clusters of micro and small scale enterprises owe their existence more to unfavorable macroeconomic conditions and less to entrepreneurial competence and dynamism their competitive potential is limited support measures should mainly aim at improving the conditions for survival since these clusters are important in creating employment opportunities the impetus should be to break through the low skills low investment vicious circle more advanced and differentiated mass producers have been flourishing in the import substitution era but are coming under enormous pressure with the transition to open economies in these clusters the main challenge is to create an environment that stimulates and supports learning innovation and constant upgrading clusters of transnational corporations are typically dominated by foreign firms not only at the final assembly stage but also in parts production these clusters often are showcases of best practice manufacturing this can be used to stimulate the upgrading of domestic firms notably by involving them in the supply chain of transnationals

determinants of horizontal spillovers from fdi evidence from a large meta analysis summary the voluminous empirical research on horizontal productivity spillovers from foreign investors to domestic firms has yielded mixed results in this paper we collect 1 205 estimates of spillovers and examine which factors influence spillover magnitude our results suggest that horizontal spillovers are on average zero but that their sign and magnitude depend systematically on the characteristics of the domestic economy and foreign investors foreign investors who form joint ventures with domestic firms and who come from countries with a modest technology edge create the largest benefits for the domestic economy

spillovers from foreign direct investment within or between industries this paper contributes an estimation framework to measure both technological and linkage externalities from foreign direct investment fdi empirical research dealt mainly with intra industry spillovers from fdi with restrictive treatment of inter industry effects until recently however as optimal organization of the multinational corporation mnc involves minimization of profit losses due to leakage of technical information to competitors host country firms within the mnc s sector experience limited productivity gains ensuing fdi host country producers in other sectors may benefit for example mncs transfer knowledge to local downstream clients or outsource to local upstream suppliers hence fdi substitutes within sector domestic investment but complements it across sectors the net impact on aggregate capital formation by host country producers hinges on the interaction between linkages and spillovers estimations based on the colombian manufacturing census yield the sectoral pattern of fdi spillovers displaying knowledge propagation between but not within industries the findings reveal outsourcing relationships of mncs with local upstream suppliers as the channel of diffusion

remittances and economic growth a meta analysis abstract expatriate workers remittances represent an important source of financing for low and middle income countries no consensus however has yet emerged regarding the effect of remittances on economic growth in a quantitative survey of 538 estimates reported in 95 studies we find that approximately 40 of the studies report a positive effect 40 report no effect and 20 report a negative effect our results indicate publication bias in favor of positive effects correcting for the bias using recently developed techniques we find that the mean effect of remittances on growth is still positive but economically small nevertheless our results uncover noticeable regional differences remittances are growth enhancing in asia but not in africa studies that do not control for alternative sources of external finance such as foreign aid and foreign direct investment mismeasure the effect of remittances finally time series studies and studies ignoring endogeneity issues report systematically larger effects of remittances on growth

why can collective action fail in local agri food systems a social network analysis of cheese producers in aculco mexico collective trademark and regional product qualification in food processing industries have become a growing challenge for farmers in developing countries this challenge is the target of collective action based programs aiming at framing the cooperation context that would enable a local community to turn inherited resources and know how into new market opportunities literature acknowledges that social capital is a crucial local resource for successful collective actions since it is a source of trust and collective commitment within a community this paper deals with testing the role of this resource in the collective action case of the cheese producers in aculco mexico focusing on the connectedness dimension of social capital we propose an original methodology that relies on the multiplex and structural properties of social networks this allows us to disentangle the opposite and ambivalent effects of social capital on the ability of a community to reach the goals assigned by the collective action program our empirical study shows that these critical properties can work in favor of adherence to collective action but can also create elite capture clannish behaviors and entry barriers thus showing a failure of collective action

farmer organization collective action and market access in meso america abstract farmer organization and collective action are often seen as key factors in enhancing farmers access to markets often too little attention is directed at a the most appropriate types of organization b whether organization makes less or more sense in the case of producers of an undifferentiated commodity or a higher value product c whether the public or private sector is best placed to support farmer organizations and d the conditions necessary for ensuring their economic viability research in mexico and central america explored these issues for commodity maize and high value vegetables respectively the benefits of farmer organization are more evident in the vegetable sector characterized by high transaction costs associated with market access however horticultural farmer organizations in honduras and el salvador include less than 5 of total horticultural producers this is possibly due to farmer organizations limited business skills and non replicable organizational models there is less incentive for maize farmers to organize to access output markets as the transaction costs are relatively low the benefits of maize farmer organization are clearer when it comes to accessing inputs such as credit seed and fertilizer farmer organization is a critical factor in making markets work for the poor but the role and timing of public and private investment in these organizations is poorly understood

technological spillovers from multinational firms this paper aims to identify genuine technological spillovers from multinational firms mnes to this end we use data on r d from mnes to measure spillovers while most of the existing literature uses output to measure the foreign presence in an industry what we call output based spillovers in line with the existing literature we distinguish between horizontal spillovers i e intra industry linkages and vertical spillovers i e backward or downstream and forward or upstream inter industry linkages our results show that the three types of technological spillovers from mnes are positive with the horizontal spillovers the larger ones followed by backward spillovers the effect of forward spillovers is much smaller in magnitude moreover we find that not controlling for industry size i e technological spillovers from all firms in an industry leads to underestimating both horizontal and backward spillovers from mnes and to overestimating forward spillovers from mnes finally we find that the distinction between technological and output based spillovers is of great relevance the size of backward technological spillovers is approximately 44 of the size of output based backward spillovers while for horizontal spillovers both types of spillovers are quite similar importantly output based forward spillovers are negative while technological forward spillovers are positive

social desirability opportunism and actual support for farmers market organisations in ethiopia one of the striking issues in the literature on farmers market organisations fmos is that farmers generally report quite positive opinions regarding the services of their fmo while at the same

the nature and determinants of socioeconomic inequality among peasant households in southern sudan abstract real income inequality among rural households in tropical africa sometimes may be imperceptible to the casual observer nevertheless the detailed information painstakingly collected from a small sample of peasant households in an area of southern sudan reported here shows that such income inequality is quite significant the great majority of the population are no doubt absolutely poor in the sense that many basic needs goods and services are scarce and income and food security are precarious yet in a situation where arable land is relatively abundant some households are much better off than others indeed our data suggest that inequality is extreme between rural households in terms of a wide variety of welfare indicators including the level of current household income set in the context of the chayanov model of peasant household decision making the paper explores the nature extent and principal determinants of income inequality in the sampled area this study establishes that those households which are able to relax the family labor constraint on the size of agricultural harvests and to diversify their principal sources of income away from purely subsistence levels of crop output into production of a marketable surplus into off farm income generating activities and into formal sector wage employment are able to attain a relatively higher standard of living according to a range of locally based welfare indicators

does cooperative membership improve household welfare evidence from apple farmers in china this paper examines the impact of cooperative membership on farm performance indicators such as apple yields net returns and household income using cross sectional data from a survey of farmers in china an endogenous switching regression model that accounts for selection bias is employed in the analysis the empirical results reveal that cooperative membership exerts a positive and statistically significant impact on apple yields farm net returns and household income a disaggregated analysis also reveals that small scale farms tend to benefit more from cooperatives than medium and large farms

measuring the income elasticity of water demand the importance of publication and endogeneity biases we present the first study that examines the effects of publication selection in the literature estimating the income elasticity of water demand paradoxically more affected by publication selection are the otherwise preferable estimates that control for endogeneity attempting to correct simultaneously for publication and endogeneity biases we find that the mean underlying elasticity is approximately 0 15 or less the result is robust to controlling for more than 30 characteristics of the estimates and accounting for model uncertainty the differences in the reported estimates are systematically driven by differences in the tariff structure regional coverage data granularity and control for temperature

income elasticity of gasoline demand a meta analysis abstract in this paper we quantitatively synthesize empirical estimates of the income elasticity of gasoline demand reported in previous studies the studies cover many countries and report a mean elasticity of 0 28 for the short run and 0 66 for the long run we show however that these mean estimates are biased upwards because of publication bias the tendency to suppress negative and insignificant estimates of the elasticity we employ mixed effects multilevel meta regression to filter out publication bias from the literature our results suggest that the income elasticity of gasoline demand is on average much smaller than reported in previous surveys the mean corrected for publication bias is 0 1 for the short run and 0 23 for the long run

collective action for smallholder market access abstract the opportunity for smallholders to raise their incomes increasingly depends on their ability to compete in the market yet there are many failures in rural markets in developing countries that make it difficult for them to do this understanding how collective action can help address the inefficiencies coordination problems or barriers to market access is particularly important this paper draws on the case studies in this special issue and on other literature to examine the conceptual issues and empirical evidence on the role of collective action institutions in improving market access for the rural poor applying insights from studies of collective action in natural resource management the paper examines what conditions facilitate effective producer organizations for smallholders market access with special attention to the characteristics of user groups institutional arrangements types of products staples perishables and other commodities markets local domestic and international and external environment the paper also identifies policies and interventions that facilitate collective action for market access among smallholders and examines whether the public sector private sector and or civil society is best positioned to provide such interventions

habit formation in consumption a meta analysis abstract we examine 597 estimates of habit formation reported in 81 published studies the mean reported strength of habit formation equals 0 4 but the estimates vary widely both within and across studies we use bayesian and frequentist model averaging to assign a pattern to this variance while taking into account model uncertainty studies employing macro data report consistently larger estimates than micro studies 0 6 vs 0 1 on average the difference remains 0 5 when we control for 30 factors that reflect the context in which researchers obtain their estimates such as data frequency geographical coverage variable definition estimation approach and publication characteristics we also find that evidence for habits strengthens when researchers use lower data frequencies employ log linear approximation of the euler equation and utilize open economy dsge models moreover estimates of habits differ systematically across countries

the future of small farms new directions for services institutions and intermediation summary efficient pre and post harvest services are essential if small farms in high potential areas are to intensify production contribute to economic growth and reduce poverty they also matter if small farms in marginal areas are to manage their natural resource base in the face of growing population pressure and climate change difficulties that smallholders face in accessing services are reviewed showing how incentives for commercial delivery of services to smallholders differ between staple food traditional cash crop and high value product supply chains the major challenge in service delivery to smallholders in much of africa concerns coordination of service development and delivery different forms of intermediary institution for achieving such coordination are examined

a meta analysis of the indirect impact of foreign direct investment in old and new eu member states understanding productivity spillovers in this paper we summarise combine and explain recent findings from firm level empirical literature focusing on the indirect impact of foreign direct investment fdi on economic performance measured as productivity in the enlarged europe we have reviewed 52 quantitative studies released between 2000 and 2015 and codified 1 133 estimates we run a regression of regressions which measures the strength of the fdi productivity relationship taking advantage of large number of high quality studies on fdi and its role in explaining the growth in firms productivity in europe we adopt recent meta regression analysis methods funnel asymmetry and precision estimate tests and precision effect estimate with standard errors to explain the heterogeneous impact of fdi this paper assesses the country specific impact of fdi on firms performance after taking publication selection bias econometric modelling and the individual studies characteristics fully into account our results show that on average fdi has a positive indirect impact on productivity the impact is especially significant in selected european countries and we interpret this as a sign of better absorptive capacities in those countries

quality and productivity in the competitive strategies of brazilian industrial enterprises abstract after a long period of protected development brazilian industry is facing the new competition an analysis of manufacturing based competitive strategies in developed countries shows a trajectory of development of competitiveness starting from price and moving through quality time diversity and uniqueness the competences needed for each element are cumulative this poses challenges for firms in developing countries which are faced with a sudden exposure to new standards of competitiveness they may recognize the need for better quality or diversity but not have the basis for achieving them the problems facing firms in brazil as they wrestle with these problems in a liberalizing economy are discussed
