the environmental kuznets curve environmental protection policy and income distribution abstract the effect of economic growth on pollution emissions differs substantially among high income countries i address this issue by analyzing public environmental policy decisions individual heterogeneity relative income effect and the political framework in which policy decisions are taken determine the emergence of the downward sloping segment of the environmental kuznets curve ekc income inequality produces a gap between the country s ability to pay for environmental protection and a country s willingness to pay i test this result by using oecd data on public r d expenditure for environmental protection the conclusion is that contrary to the ek hypothesis moments of the income distribution function other than the mean may be important for the emergence of a virtuous path of sustainable growth in high income countries

are household production decisions cooperative evidence on pastoral migration and milk sales from northern kenya market based development efforts frequently create opportunities to generate income from goods previously produced and consumed within the household production within the household is often characterized by a gender and age division of labor market development efforts to improve wellbeing may lead to unanticipated outcomes if household production decisions are noncooperative we develop and test models of household decision making to investigate intrahousehold decision making in a nomadic pastoral setting from kenya our results suggest that household decisions are contested with husbands using migration decisions to resist wives ability to market milk

sources of aggregate labour productivity growth in canada and the united states abstract in this paper we propose a decomposition technique to examine the sources of industrial contribution to aggregate labour productivity growth we show that in terms of pure labour productivity growth the manufacturing and service sectors contributed equally to the aggregate canada u s labour productivity growth gap during the 1987 98 period but in terms of total industrial contributions which also take into account the contributions from a change in relative size the service sector was the largest contributor we also find that high labour productivity growth industries did not attract resources from stagnant industries a phenomenon consistent with baumol s cost disease of stagnant industries jel classification o47 c43

loose fruit mamas creating incentives for smallholder women in oil palm production in papua new guinea summary this paper presents a case study of the introduction of a more gender equitable payment scheme for oil palm smallholders in papua new guinea women are now paid separately from their husbands for their work on family oil palm plots thereby increasing the economic incentives for women to commit labor to oil palm production the study incorporates broader local cultural and economic processes in the analysis of intra household gender and labor relations to explain how the new payment systems successfully resolved intra household disputes over labor and income the paper highlights the critical role export firms can play in enhancing women s access to commodity crop income further the paper demonstrates that by widening the framework of household analysis insights can be gained into two key questions that have received only limited attention in the literature the question of why men do not share a greater proportion of cash crop income with other family members and the apparent inability of families to resolve intra household conflicts over income

employment and structural impacts of material efficiency strategies results from five case studies abstract in order to come up with a sound assessment of the effects of material efficiency innovations on growth employment and competitiveness different economic mechanisms have to be considered from a methodological point of view the analysis must be able to account for technology specific aspects the employment impacts of five innovations are analyzed plastic and paper recycling increased life span of automobiles car sharing and bio based products time horizons for all strategies are scenarios until 2020 the economic impacts are context specific with regard to innovation technology and country the economic impacts highlight substantial structural adjustments the overall economic net impact on employment tends to be neutral to positive stronger positive economic impacts result if first mover advantages can be established

an econometric study of co2 emissions energy consumption income and foreign trade in turkey abstract this study attempts to empirically examine the dynamic causal relationships between carbon emissions energy consumption income and foreign trade in the case of turkey using the time series data for the period 1960 2005 this research tests the interrelationship between the variables using the bounds testing to cointegration procedure the bounds test results indicate that there exist two forms of long run relationships between the variables in the case of first form of long run relationship carbon emissions are determined by energy consumption income and foreign trade in the case of second long run relationship income is determined by carbon emissions energy consumption and foreign trade an augmented form of granger causality analysis is conducted amongst the variables the long run relationship of co2 emissions energy consumption income and foreign trade equation is also checked for the parameter stability the empirical results suggest that income is the most significant variable in explaining the carbon emissions in turkey which is followed by energy consumption and foreign trade moreover there exists a stable carbon emissions function the results also provide important policy recommendations

unwanted effects of european union environmental policy to promote a post carbon industry the case of energy in the european ceramic tile sector global warming combined with low carbon transition plans is threatening the future of high energy consumption industry sectors in the european union eu the need to respond to environmental challenges is demonstrated by support for international level energy policies and legal requirements such as the kyoto protocol which the eu supports and increased eu level environmental legislation and energy policies the effect of these initiatives is gradually transforming industrial activities in the eu however since not all countries have adopted these policies evaluation of their net effect needs to take account also of side effects such as delocalization of industry activity and the legal environmental frameworks in the countries where companies have chosen to relocate this paper analyses eu energy policy and its impact on a particular energy intensive industry the european ceramic tile sector the discussion in this paper is not about the purpose of eu legislation but about its effects on a specific industry the effect of policy on industry is not a new topic but the question of the unwanted effects of environmental and energy policy on european industry is becoming more relevant as the struggle to achieve a post carbon europe increases in focussing on a specific set of eu legislation on a particular industry this article adds to the debate by showing the negative effects of policy mechanisms the need for a scientific evaluation of the systemic changes required for a transition to a resource efficient green and competitive low carbon economy outlined in the 7th environment action programme is highlighted it is suggested that the eu should periodically re evaluate its emissions trading scheme legislation to include specific actions and a follow up system which would prevent the best performing environmental companies from delocalizing or shutting down

a growing trend toward knowledge work in canada abstract this paper answers three questions related to the growing trend toward knowledge occupations in canada i what was the magnitude of the trend between 1971 and 1996 ii was the trend a widespread phenomenon or was it restricted to specific industries iii what are the proximate causes of the trends using five censuses 1971 1981 1986 1991 1996 and the input output i o data the paper provides evidence that the canadian economy is becoming increasingly knowledge based although the upgrading trends differ across knowledge occupations moreover we find that this phenomenon is spread across all industrial sectors finally using a decomposition analysis borrowed from wolff and baumol three factors the substitution effect the productivity lag effect and the demand effect have been examined in order to shed some light on these trends we find that these effects vary according to the nature of the knowledge involved in these different groups of occupations thus reflecting not only the importance of the technological change skill bias but also the increasing complexity of controlling and managing the new economic activities

decomposing industrial co2 emissions of southern european countries into production and consumption based driving factors abstract industry is a leading economic sector in european countries as well as a major carbon emitter european industry has been quite successful in abating the environmental pressures and carbon emissions and increasing its energy efficiency from production over the last years however focusing only on the production side may not lead to the desired sustainable development since there are other forces such as the international trade and consumption patterns which also shape the evolution of industrial co 2 emissions the aim of this study is to investigate how changes in production and consumption of industrial products affect the co 2 emissions of industries in four southern european countries during the period 2000 2011 to this purpose a new model of index decomposition analysis is developed in order to decompose the change in co 2 emissions of the industrial sectors of greece italy spain and portugal moreover the examined period in this study is split into two sub periods 2000 2008 and 2008 2011 in order to investigate the impact of the recent economic crisis on both the driving factors and industrial co 2 emissions the overall evolution of industrial co 2 emissions was quite similar in all the countries and the decomposition results of the two sub periods revealed substantial homogeneity across countries two production based driving factors the economic activity and the energy intensity were the main driving factors which shaped the total change in co 2 emissions of industries in the examined countries the consumption based driving factors contributed mostly to the increase in industrial co 2 emissions but not at the same level as the production based ones furthermore industrial production was more significantly affected by the economic crisis than consumers expenditures the decomposition results performed at a sectoral level revealed that it was difficult for southern european consumers to switch to a more environmentally conscious use of industrial products and their consumption preferences were not significantly affected by the consequences of the economic crisis

dyke maintenance and other stories some neglected types of public goods the orthodox summation model of a pure nonexcludable public good assumes that each individual consumes a quantity of public good defined as the sum of all individuals contributions to that good recently hirshleifer 1983 1985 has analyzed models that do not fall within this class at one extreme is the weakestlink in which the total quantity available to each consumer equals the smallest individual contribution at the other is the best shot in which the total quantity available equals the largest individual contribution hirshleifer s example of the weakest link case concerns a circular region of which each citizen owns a pie shaped slice the perimeter is marked by a dyke floods may penetrate the weakest point of the dyke and cause damage equally throughout the region each citizen decides the height and state of repair of that section of the dyke adjoining his piece of land its maintenance constituting his contribution to the public good thus the level of protection enjoyed by all is determined by the least well maintained section of the dyke an example of the best shot case concerns a number of antimissile batteries ringing a city firing at an incoming icbm all that matters is the accuracy of the best shot bliss and nalebuff 1984 discuss dragon slaying as another example of a best shot situation section ii of this paper introduces a class of functions of which the summation weakest link and best shot are examples section iii analyzes the properties of equilibrium when consumers have identical tastes and incomes section iv analyzes the implications of income redistribution in the summation case the equilibrium is unaffected by the initial redistribution over a range and outside that range transfers help the recipient and hurt the donor within the broader class of models however the invariance property does not generally hold and there may be opportunities for paretoimproving income redistribution i give an example similar to the weakest link case in which a pareto improving redistribution is

index decomposition analysis applied to co2 emission studies index decomposition analysis ida was first extended from energy consumption to energy related co2 emission studies in 1991 since then many studies have been reported covering various countries and emission sectors however unlike the case of energy consumption studies a comprehensive literature survey that focuses specifically on emission studies has so far not been reported in this paper we attempt to fill this gap by reviewing 80 papers appearing in peer reviewed journals from 1991 to 2012 in this application area the first part of this paper deals with the developments with regard to the ida approaches used by researchers and the scope and focus of their studies in the second part the empirical results reported in the surveyed studies are analyzed consolidated and presented by emission sector the objective is to reveal the relative contributions of key effects on changes in the aggregate carbon intensity and this is done by emission sector and by country the findings of both parts are useful in understanding the development of ida in the application area of emission study as well as the key drivers of aggregate carbon intensities in the past and their possible future developments

contract farming and smallholder incentives to produce high quality experimental evidence from the vietnamese dairy sector in emerging markets for high value food products in developing countries processing companies search for efficient ways to source raw material of high quality one widely embraced approach is contract farming but relatively little is known about the appropriate design of financial incentives in a small farm context we use the example of the vietnamese dairy sector to analyze the effectiveness of existing contracts between a processor and smallholder farmers in terms of incentivizing the production of high quality milk a framed field experiment is conducted to evaluate the impact of two incentive instruments a price penalty for low quality and a bonus for consistent high quality milk on farmers investment in quality improving inputs statistical analysis suggests that the penalty drives farmers into higher input use resulting in better output quality the bonus payment generates even higher quality milk we also find that input choice levels depend on farmers socio economic characteristics such as wealth while individual risk preferences seem to be less important implications for the design of contracts with smallholders are discussed

change in energy related co2 carbon dioxide emissions in portuguese tourism a decomposition analysis from 2000 to 2008 abstract tourism is an activity with great potential in portugal at a time of economic crisis tourism is seen as an opportunity to boost the economy and provide sustainable economic growth this strategic path based on tourism has to be accomplished in order to make better use of the economic advantages but at the same time respecting the environment and environmental goals to which portugal is committed so it becomes important to analyze what effects contribute more to emissions in this sector as well as which tourism subsectors are more responsible for the increase of emissions the objective of this work is to identify the effects in which co2 carbon dioxide emissions in tourism can be broken down and analyzed as well as their evolution and which of them has more importance in determining emissions for that in this study a decomposition technique based on logarithmic mean divisia index was used in the 2000 2008 period for five tourism subsectors in portugal in general tourism activity is the most important effect energy mix carbon intensity and energy intensity effects also proved important

co2 emissions from household consumption in india between 1993 94 and 2006 07 a decomposition analysis abstract co 2 emission from anthropogenic activities is one of the major causes of global warming india being an agriculture dependent country global warming would mean monsoon instability and consequent food scarcity natural disasters and economic concerns however with proper policy interventions co 2 emissions can be controlled input output analysis has been used to estimate direct and indirect co 2 emissions by households for 1993 94 1998 99 2003 04 and 2006 07 complete decomposition analysis of the changes in co 2 emissions between 1993 94 and 2006 07 has been done to identify the causes into pollution energy intensity structure activity and population effects according to broad household consumption categories results indicate that activity structure and population effects are the main causes of increase in co 2 emission from household fuel consumption to identify the causes at the sectoral level a second decomposition has been done for changes between 2003 04 and 2006 07 to identify the causes in the next stage finally alternative energy policy options have been examined for each consumption category to reduce emissions combined strategies of technology upgradation fuel switching and market management in order to reduce co 2 emissions for sectors like batteries other non electrical machinery construction and electronic equipments including television for which all the effects are positive need to be adopted

sustainable consumption and production governance in countries in transition abstract unsustainable consumption and production patterns have brought human civilization to the brink of a global disaster alteration of these patterns to minimize adverse environmental impacts has become the key question of survival a question relevant for every country and citizen in this paper we are looking at trends of consumption and production in the post soviet republics these countries have a common history but they took different routes to development they are at different stages of economic growth and political processes with differences also in consumption and production related environmental pressures and policies this study is based on statistical data analysis and snap shot surveys of national experts from non governmental organizations reflecting their views and observations which often differ from official positions of national governments and international organizations in order to draw conclusions about the possibilities for further development we analyze various sustainable consumption and production indicators policy developments progress achieved and the main challenges behind sustainable consumption and production governance in these countries sustainable consumption and production policy in the countries of the region is fragmented and none of the countries uses a holistic integrated approach the influence of the eu seems to be critical for advancing sustainable development principles however the eu accession does not address the growth effect which is the main driver behind increasing environmental pressures related to consumption there is still a long way to go from this mosaic of policy elements to a coherent policy with adequate institutional support and funding mechanisms

impact of household consumption on co2 emissions danish household consumption increased by 58 over the period 1966 1992 while co2 emissions only increased by 7 using decomposition analysis we investigated the global co2 impact of danish household consumption from 1966 to 1992 our conclusion is that overall growth in private consumption but not changes in the composition of consumption is the key to understanding the increase in co2 emissions however the effect of growth in private consumption has been partly offset by substantial energy conservation in the energy supply and manufacturing sectors

common trends and drivers of co2 emissions and employment a decomposition analysis in the industrial sector of selected european union countries the countries of the european union face the challenge of reversing the declining role of industry and achieving their targets for sustainable development combining industrial growth with fewer environmental repercussions and more jobs this paper uses a decomposition analysis in order to quantify the effect of the driving factors on two indicators of sustainable industrial development co2 emissions and employment in five european union countries during 2000 2011 the decomposition method applied is the log mean divisia index i and the models developed comprise some common or closely related driving factors the parallel investigation of the factors affecting the two indicators offers useful insights into relevant complementary and or antithetical effects the timeframe of the study is divided into two time periods before and after the start of the economic crisis 2000 2007 and 2007 2011 respectively this time division enables the evaluation of the impacts of the economic crisis directly on the drivers and indirectly on the two indicators it was deduced that in both time periods the two main drivers of industrial co2 emissions and employment were economic growth and resource intensity which counterbalance each other structural changes appeared to have a rather marginal effect even if the general tendency was the expansion of less energy labour intensive sectors finally changes in the fuel mix used in industry were beneficial to emissions reduction in all the examined countries especially in the second time period the results obtained show that the examined eu countries have not found a solid path towards sustainable and inclusive industrial development yet the stronger economies seem to move faster to this direction though

the lmdi approach to decomposition analysis a practical guide in a recent study ang energy policy 32 2004 compared various index decomposition analysis methods and concluded that the logarithmic mean divisia index method is the preferred method since the literature on the method tends to be either too technical or specific for most potential users this paper provides a practical guide that includes the general formulation process summary tables for easy reference and examples

subsidization to induce tipping abstract in binary choice games with strategic complementarities and multiple equilibria we characterize the minimal cost subsidy program to guarantee agents play the pareto optimal equilibrium these subsidies are generally asymmetric whether or not agents are identical and even if private values are anonymous

does history matter only when it matters little the case of city industry location when will an industry subject to agglomeration economies move from an old high cost site to a new low cost site it is argued that history in the form of sunk costs resulting from the operation of many firms at a site creates a first mover disadvantage that can prevent relocation it is demonstrated that developers of industrial parks can partly overcome this inertia through discriminatory pricing of land over time and empirical evidence is provided that they actually engage in such behavior it is also shown that other aspects of developer land sale strategy can be a source of information on the nature of interfirm externalities

towards a national circular economy indicator system in china an evaluation and critical analysis abstract it is widely acknowledged that china s economic miracle has been achieved at the expense of its natural capital and environment in order to deal with this problem the circular economy ce has been chosen as a national policy for sustainable development national laws and regulations have been enacted to facilitate the implementation of ce and national ce demonstration projects have been initiated such that national benchmarking activities could be completed china is the first country to release nationally focused ce indicators so that objective and credible information on the status of ce implementation can be recognized these ce indicators are valuable metrics for policy and decision makers and can help achieve ce goals and outcomes this unique indicator system has not been communicated to international communities this paper aims to more broadly introduce this unique national ce indicator system china s ce efforts are first detailed with various provisions of the national indicator system a critical analysis of such an indicator system is presented we show that certain benefits can be gained but substantive revision is also needed due to the lack of a comprehensive set of sustainability indicators which should include social business indicators urban industrial symbiosis absolute material energy reduction and prevention oriented indicators concerns related to barriers on implementation are also presented in this paper the knowledge gained from chinese efforts on ce indicators are valuable to both developed and developing nations seeking to implement sustainable development measures within their regulatory policies

globalization privatization and vertical coordination in food value chains in developing and transition countries food and agricultural commodity value chains in developing and transition countries have undergone tremendous changes in the past decades companies and property rights have been privatized markets liberalized and economies integrated into global food systems the liberalization and privatization initially caused the collapse of state controlled vertical coordination more recently private vertical coordination systems have emerged and are growing rapidly as a response to consumer demand for food quality and safety on the one hand and the farms production constraints caused by factor market imperfections in this article we 1 demonstrate the importance of these changes 2 discuss the implications for efficiency and equity and 3 provide empirical evidence on the effects in several developing and transition countries

the economic growth enigma capital labour and useful energy abstract we show that the application of flexible semi parametric statistical techniques enables significant improvements in model fitting of macroeconomic models as applied to the explanation of the past economic growth since 1900 in us uk and japan the new results demonstrate quite conclusively the non linear relationships between capital labour and useful energy with economic growth they also indicate that output elasticities of capital labour and useful energy are extremely variable over time we suggest that these results confirm the economic intuition that growth since the industrial revolution has been driven largely by declining energy costs due to the discovery and exploitation of relatively inexpensive fossil fuel resources implications for the 21st century which are also discussed briefly by exploring the implications of an aceges based scenario of oil production are as follows a the provision of adequate and affordable quantities of useful energy as a pre condition for economic growth and b the design of energy systems as technology incubators for a prosperous 21st century

energy intensity developments in 40 major economies structural change or technology improvement this study analyzes energy intensity trends and drivers in 40 major economies using the wiod database a novel harmonized and consistent dataset of input output table time series accompanied by environmental satellite data we use logarithmic mean divisia index decomposition to 1 study trends in global energy intensity between 1995 and 2007 2 attribute efficiency changes to either changes in technology or changes in the structure of the economy and 3 highlight sectoral and regional differences we first show that heterogeneity within each sector across countries is high these general trends within the sectors are dominated by large economies first and foremost the united states in most cases heterogeneity is lower within each country across the different sectors regarding changes of energy intensity at the country level improvements between 1995 and 2007 are largely attributable to technological change while structural change is less important in most countries notable exceptions are japan the united states australia taiwan mexico and brazil where a change in the industry mix was the main driver behind the observed energy intensity reduction

the modest environmental relief resulting from the transition to the service economy a service transition is supposed to lead to the decline of energy intensity energy gdp we argue that this interpretation is overly optimistic because the shift to a service economy is somewhat of an illusion in terms of real production several recent studies of structural effects on energy intensity have made the error of using sector shares in current prices combined with gdp in constant prices which is inconsistent and ignores the different behaviour of prices across sectors we use the more correct method of sector shares in constant prices and make an attempt to single out the effect from the real service transition by using two complementary methods shift share analyses in current and constant prices and logarithmic mean divisia index lmdi for 10 developed and 3 emerging economies a service transition is rather modest in real terms the major driver of the decline in energy intensity rests within the manufacturing sector meanwhile the transition to a service sector had a small downward impact on energy intensity in 7 of the developed countries and no impact in the others for emerging economies like brazil mexico and india it is the residential sector that drives energy intensity down because of the declining share of this sector as the formal economy grows and as a consequence of switching to more efficient fuels less

wages for wives renegotiating gender and production relations in contract farming in the dominican republic abstract this study analyzes the intersection of gender and production relations in small scale contracting in nontraditional agriculture the case of the processing tomato industry in the dominican republic exemplifies patterns found throughout the region building on a critique of unitary household models i analyze the gendered relations mobilizing resources for contract farming as appears common contracting has heightened demand for women s farm labor contracting has simultaneously provided women with openings for contesting the appropriation of their unpaid labor and many women are claiming payment for work in contract farming this case demonstrates the importance of gender issues in informing contract farming debates and policy interventions

from green growth to sound policies an overview abstract green growth is an attractive slogan with a variety of possible meanings this essay critically examines several potential meanings of this slogan and provides a brief overview of some of the main implications of the other papers in this special issue taken together these papers argue for the importance of careful analysis of energy environmental policies particularly ambitious ones claiming to offer huge benefits with little or no cost

climate change policy market structure and carbon leakage abstract the 1997 kyoto protocol on climate change obliges the industrialized countries to initiate the international effort of abating anthropogenic greenhouse gas ghg emissions if such an initiative is to be taken the associated competitive effects may lead to significant relocation of developed countries energy intensive production this paper examines this issue i adopt an oligopolistic structure combined with increasing returns to scale production technologies to represent the strategic interaction among the firms producing energy intensive products this representation is then embedded within a multi regional computable general equilibrium model which in turn is used for quantifying these relocational effects the results suggest that significant relocation of energy intensive industries away from the oecd may occur depending on the type of market structure with leakage rates as high as 130 in which case ghg control policies in the industrialized countries actually lead to higher global emissions

loyalty exit and enforcement evidence from a kenya dairy cooperative organizations depend on members loyalty for their success studying a cooperative s attempt to increase deliveries by members we show that the threat of sanctions leads to highly heterogeneous response among members despite the cooperative not actually enforcing the threatened sanctions positive effects for some members persist for several months other members exit stopping delivering altogether among non compliant members we document substantial heterogeneity in beliefs about the legitimacy of the sanctions this lack of common understanding highlights the role played by managers in organizations and provides a candidate explanation for lack of sanctions enforcement documented by ostrom 1990 and other studies

a new frontier approach to model the eco efficiency in european countries abstract this study aims to evaluate the resource and environment efficiency problem of european countries we specify a new stochastic frontier model where gross domestic product gdp is considered as the desirable output and greenhouse gases ghg emissions as the undesirable output capital labor fossil fuels and renewable energy consumption are regarded as inputs gdp ghg ratio is maximized given the values of the other four variables the study is divided into two distinct periods 2000 2004 and 2005 2011 this division is related to the implementation of the kyoto protocol in 2005 and will allow us to evaluate the difference between the levels of efficiency before and after the establishment of environmental targets since stochastic frontier models are typically ill posed a new maximum entropy approach to assess technical efficiency which combines information from the data envelopment analysis and the structure of composed error from the stochastic frontier approach without requiring distributional assumptions is presented in this work

the social performance and distributional consequences of contract farming an equilibrium analysis of the arachide de bouche program in senegal abstract this paper is an empirical analysis of the impact of a contract farming program in senegal we examine the access of poorer community members to contracts and the effect of the program on the income of participants the program performs very well on both counts participants and nonparticipants are indistinguishable by wealth measures and farmers increase their income substantially by participating in the program we attribute the former to the program s mobilization of local information through its use of village intermediaries permitting the substitution of social collateral for physical collateral and making the program more accessible to the poor

foreign trade and declining pollution in sweden a decomposition analysis of long term structural and technological effects this article examines whether there exists any causal relationship between foreign trade and declining pollution in developed countries in other words do developed countries outsource their problems to less developed countries rather than solve them the case study is the swedish economy and the two environmental indicators employed are energy consumption and co2 emissions no causal relationships are found since sweden has long been a net exporter of embodied energy and co2 and continues to be so after 1970 when energy consumption stabilizes and co2 emissions decline in addition the ratios of net exported energy and co2 to total consumption remain stable which means there were no effects on the energy intensity or co2 intensity either these results suggest that internal forces like efficiency improvements changed consumption patterns and transformation of the energy system have been crucial for relative environmental improvement in sweden while foreign trade has played no role

smallholder participation in contract farming comparative evidence from five countries summary supermarkets specialized wholesalers processors and agro exporters are transforming the marketing channels into which smallholder farmers sell produce in low income economies we develop a conceptual framework with which to study contracting between smallholders and a commodity processing firm we then synthesize results from empirical studies of contract farming arrangements in five countries ghana india madagascar mozambique and nicaragua the resulting meta narrative documents patterns of participation the welfare gains associated with participation reasons for nonparticipation the significant extent of contract noncompliance and the considerable dynamism of these value chains as farmers and firms enter and exit frequently

finding missing markets and a disturbing epilogue evidence from an export crop adoption and marketing intervention in kenya in much of the developing world many farmers grow crops for local or personal consumption despite export options that appear to be more profitable thus many conjecture that one or several markets are missing this paper reports on a randomized controlled trial conducted by drumnet in kenya that attempts to help farmers adopt and market export crops drumnet provides smallholder farmers with information about how to switch to export crops makes in kind loans for the purchase of the agricultural inputs and provides marketing services by facilitating the transaction with exporters the experimental evaluation design randomly assigns pre existing farmer self help groups to one of three groups 1 a treatment group that receives all drumnet services 2 a treatment group that receives all drumnet services except credit or 3 a control group after one year drumnet services led to an increase in production of export oriented crops and lower marketing costs this translated into household income gains for new adopters however one year after the study ended the exporter refused to continue buying the cash crops from the farmers because the conditions of the farms did not satisfy european export requirements drumnet collapsed in this region as farmers were forced to sell to middlemen and defaulted on their loans the risk of such events may explain at least partly why many seemingly more profitable export crops are not adopted

behavioral economics and public policy a pragmatic perspective the debate about behavioral economics the incorporation of insights from psychology into economics is often framed as a question about the foundational assumptions of economic models this paper presents a more pragmatic perspective on behavioral economics that focuses on its value for improving empirical predictions and policy decisions i discuss three ways in which behavioral economics can contribute to public policy by oering new policy tools improving predictions about the eects

agrifood industry transformation and small farmers in developing countries summary this article introduces this special issue on the rapid transformation of the agrifood industry in developing countries and its effects on small farmers we review the literature from the late 1980s to the present and find evidence first of food processing then retail transformation and mixed evidence of impacts on small farmers both inclusion particularly with resource providing contracts and exclusion sometimes from scale constraint sometimes from inadequate non land assets the special issue papers contribute to the debate by confirming the mix of cases of inclusion and exclusion the cases are main in horticulture and dairy key hopes for smallholder development

impact of third party contract enforcement in agricultural markets a field experiment in vietnam we study the effect of alleviating the information asymmetry regarding product quality that is widespread in contracts between agricultural producers and buyers in developing countries opportunistic buyers may underreport quality levels to farmers to reduce the price that they have to pay in response farmers may curb investment thereby negatively affecting farm productivity in an experiment we entitle randomly selected smallholder dairy farmers in vietnam who are contracted by a large company to independently verify milk testing results results indicate that treatment farmers use 12 more inputs and they also increase their output significantly some wider research and policy implications are discussed
