smallholder market participation concepts and evidence from eastern and southern africa abstract this paper reviews the evidence on smallholder market participation with a focus on staple foodgrains i e cereals in eastern and southern africa in an effort to help better identify what interventions are most likely to break smallholders out of the semi subsistence poverty trap that appears to ensnare much of rural africa the conceptual and empirical evidence suggests that interventions aimed at facilitating smallholder organization at reducing the costs of intermarket commerce and perhaps especially at improving poorer households access to improved technologies and productive assets are central to stimulating smallholder market participation and escape from semi subsistence poverty traps macroeconomic and trade policy tools appear less useful in inducing market participation by poor smallholders in the region

private food safety and quality standards for fresh produce exporters the case of hortico agrisystems zimbabwe abstract there is evidence that the challenges of complying with stricter food safety and quality standards are acting to exclude small scale producers from export supply chains for high value agricultural products the case of hortico agrisystems illustrates the considerable challenges and costs faced by supermarket suppliers in sourcing from a broad base of small scale producers in the context of evolving food safety and quality standards while small scale producers are able to achieve levels of compliance at least equal to those of large scale producers multi tiered and dynamic systems of control are required to maintain control these need to include measures that facilitate compliance incentives to reward good performance and penalties to punish non compliance in establishing a sustainable supply system in this context both exporters and small scale producers face a steep learning curve in adjusting to new requirements further emphasising the need for supply chains to be responsive to change

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

smallholder dairying under transactions costs in east africa abstract it is argued that dairying is vital to future viability of many small farms in east africa and that high transactions costs for dairy production and marketing limit participation by asset and information poor smallholders case studies from kenya and ethiopia illustrate the role of dairy cooperatives in reducing transactions costs analysis of the determinants of producer prices received by a sample of dairy producers near addis ababa suggests that different levels of access to infrastructure assets and information explain why they contemporaneously accept widely different producer prices for fluid milk

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

cooperative membership and dairy performance among smallholders in ethiopia this study assesses the impact of cooperative membership among dairy producers in selale ethiopia we selected ten impact indicators proportion of dairy income to total household income total dairy income proportion of crossbreed cows to the total number of cows in the herd indicator of technological innovation amount of feed bought another indicator of technological innovation milk production milk productivity commercialization price per liter of milk price per kg of butter and the share of milk production that is processed at the household level in order to minimize the biases that may arise by simply comparing members and non members we employed a propensity score matching technique the empirical analysis shows that cooperatives are strong in facilitating technological transformations and commercialization but weak in offering better prices these findings suggest structural trade offs between different domains of cooperatives action overall our study concludes that cooperatives can be efficient business institutions to foster rural development and food security

a policy agenda for pro poor agricultural growth abstract sub saharan africa and parts of south asia are likely to hold large numbers of very poor rural people into the foreseeable future although both history and theory suggest a pre eminent role for agricultural growth in poverty reduction in poor agrarian economies such growth today faces new difficulties many of these difficulties are endogenous to today s poor rural areas others result from broader processes of global change but some are due to changes in the dominant policy environment emphasizing liberalization and state withdrawal examination of 20th century green revolutions suggests that active state interventions were important in supporting critical stages of agricultural market development unfortunately such interventions benefits in institutional development are easily overlooked whereas their high costs are much more visible policy implications are discussed

conservation agriculture organic marketing and collective action in the honduran hillsides conservation agriculture ca is often perceived to provide win win outcomes for farmers leading to reduced erosion and off site sedimentation as well as improved soil fertility and productivity however adoption rates for ca in many regions of the world remain below expected levels this article looks at the effects of participation in organic markets and farmers organizations on the adoption of soil conservation practices based on original survey data from 241 small scale farm households in honduras we find that both participation in organic markets and farmer based groups have positive effects on the number of soil conservation practices adopted the results indicate that besides supply oriented policy measures such as the provision of technical assistance and extension demand related factors are likely to play an important role in sustainable soil management demand oriented policy measures include support for labeling initiatives and consumer education to facilitate value added product differentiation and market segmentation jel classifications q01 q12 q13 q16

addressing food security in africa via multiple livelihood strategies of women farmers abstract because food insecurity is primarily a problem of low household incomes and poverty and not just inadequate food production projects and programs for food insecure african farmers which aim at increasing production of subsistence crops may be ineffective instead government should look for ways to improve returns to farmers resources in a broader context which may include expanded opportunities for non farm microenterprises and agricultural labor this has been the conventional wisdom since the writings of amartya sen still unclear however are the implications of his thinking for the roles of african women farmers who are traditionally the food crop producers in africa and are often food insecure immediate expansion of income earning activities such as cash cropping and non farm microenterprises may not be possible for women in male headed households in many african societies where cash income is seen as part of the male domain in addition women farmers may need a long adjustment period to diversify their income sources fully because most african countries are at the early stages of structural transformation different developmental interventions both in policy and in technology are therefore needed to address food security and economic transformations in africa in the short and long term

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

evidence and implications of non tradability of food staples in tanzania 1983 1998 economic reform programmes assume that major goods are tradable such that depreciation of the real exchange rate raises the value of output compared to factor costs in domestic currency in tanzania major food staples that account for most real income are non tradables in at least one quarter of the country this conclusion is demonstrated and the implications are assessed for the constraints imposed on macroeconomic led adjustment strategies

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

invisible hands indigenous knowledge and inevitable fads challenges to public sector agricultural research in ghana abstract support for public sector agricultural research in developing countries is declining at the same time many donors feel that alternative institutions will be able to perform the functions traditionally reserved for the public sector these alternatives include private sector initiatives nongovernment organizations and farmer organizations and highly publicized special projects in agricultural development the logic of these alternatives is examined using evidence on maize research in ghana although each of the alternatives offers contributions and public sector research undoubtedly requires an overhaul emphasis is placed on the necessity of continued suport to building strong public sector agricultural research capacity

a time of agric rethinking the failure of agricultural programs in 1970s ghana summary recent interest in a new green revolution in africa has revived debate about state intervention in agricultural markets and biotechnology these debates take for granted that the first wave of green revolution interventions in africa failed to influence small scale food farmers this essay uses oral historical and documentary evidence from ghana s northern region to revisit the evidentiary basis of this assessment tracing how the production of aggregate data and changing interpretive frameworks in the 1970s and 1980s allowed policymakers to ignore the experiences of farmers the essay advocates for the role of micro historical analysis in assessing africa s recent agricultural past

estimating the environmental efficiency and marginal co2 abatement cost of coal fired power plants in china abstract we estimate the environmental efficiency reduction potential and marginal abatement cost of carbon dioxide co2 emissions from coal fired power plants in china using a novel plant level dataset derived from the first and second waves of the national economic survey which were implemented in 2004 and 2008 respectively the results indicate that there are large opportunities for co2 emissions reduction in china s coal fired power plants given that all power plants operate fully efficiently china s co2 emissions in 2004 and 2008 could have been reduced by 52 and 70 respectively accompanied by an expansion in electricity output in other words the opportunities for double dividend exist in 2004 the average marginal abatement cost of co2 emissions for china s power plants was approximately 955 yuan ton whereas in 2008 the cost increased to 1142 yuan ton the empirical analyses show that subsidies from the government can reduce environmental inefficiency but the subsidies significantly increase the shadow price of the power plants older and larger power plants have a lower environmental efficiency and marginal co2 abatement cost the ratio of coal consumption negatively affects the environmental efficiencies of power plants

a selectivity model of household food marketing behavior in sub saharan africa the agricultural household s discrete decision of whether to participate in coarse grain markets is separated here from the continuous decision of how much to sell or buy conditional on participation failure to participate in markets results from high fixed transactions costs a selectivity model endogenously switches households into alternative market participation states correcting for bias caused by the exclusion of unobservable variables affecting both discrete and continuous decisions improved market information increases the probability of participation by sellers while access to cereals processing technology increases quantities transacted by both sellers and buyers conditional on participation

smallholder market participation under transactions costs maize supply and fertilizer demand in kenya abstract this paper assessed the effects of transactions costs relative to price and non price factors on smallholder marketed surplus and input use in kenya a selectivity model was used that accounts for the effects of transactions costs assets technology and support services in promoting input use and generating a marketable surplus output supply and input demand responses to changes in transactions costs and price and non price factors were estimated and decomposed into market entry and intensity the results showed that while transactions costs indeed have significant negative effects on market participation institutional innovations such as group marketing are also emerging to mitigate the costs of accessing markets output price has no effect on output market entry and only provides incentives for increased supply by sellers on the other hand both price and non price factors have significant influence on adoption and intensity of input use overall the findings suggest that policy options are available other than price policies to promote input use and marketed surplus the paper concludes with implications for policy to induce greater input output market participation among smallholders in africa

agroindustrialization globalization and international development an overview of issues patterns and determinants this paper offers an overview for a special issue on agroindustrialization globalization and international development it sets out a conceptual framework for understanding the links among these three broad phenomena and then discusses emerging issues and evidence concerning the factors conditioning agroindustrialization in developing countries and the subsequent effects on employment poverty and the natural environment we conclude with a research agenda

the role of rural producer organizations for agricultural service provision in fragile states this article assesses the extent of external linkages and the provision of agricultural services by rural producer organizations in a post conflict setting using new survey data collected by the international food policy research institute in three provinces of the democratic republic of the congo this study finds that various internal and external factors affect the capacity of organizations to interact with external organizations external linkages ability to collect financial support from their members management capacity and formal governance structures all contribute to explaining relative performance in agricultural service delivery we also find that exogenous events affect the relative performance of rural producer organizations our results suggest that closeness to conflict reduces the capacity of producer organizations to provide agricultural services

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

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

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

hedonic wages and labor market search this article investigates the consequences of labor market search for the theory of hedonic wages we find that the introduction of search has surprising consequences for the theory of hedonic wages in particular we demonstrate that the equilibrium distribution of wage and nonwage amenity bundles generally bears little resemblance to workers underlying preferences a consequence of this analysis is that estimates of workers marginal willingness to pay derived from the conventional hedonic wage methodology are biased in addition we demonstrate that search generates differences between firm level and employee level data that can cause substantial deviations in the estimates of hedonic wage equations

the workers value of the remaining employment contract duration this paper introduces and applies a method for estimating workers marginal willingness to pay for job attributes employing data on job search activity worker s willingness to pay for the remaining duration of the employment contract is derived we provide evidence that workers attach substantial value to the remaining contract duration a temporary worker with a remaining contract of 6 months is willing to pay about 10 of the wage to increase the contract by one month

a revised tobit procedure for mitigating bias in the presence of non zero censoring with an application to milk market participation in the ethiopian highlands fixed transactions costs that prohibit exchange engender bias in supply analysis due to censoring of the sample observations the associated bias in conventional regression procedures applied to censored data and the construction of robust methods for mitigating bias have been preoccupations of applied economists since tobin econometrica 26 1958 24 this literature assumes that the true point of censoring in the data is zero and when this is not the case imparts a bias to parameter estimates of the censored regression model we conjecture that this bias can be significant affirm this from experiments and suggest techniques for mitigating this bias using bayesian procedures the bias mitigating procedures are based on modifications of the key step that facilitates bayesian estimation of the censored regression model are easy to implement work well in both small and large samples and lead to significantly improved inference in the censored regression model these findings are important in light of the widespread use of the zero censored tobit regression and we investigate their consequences using data on milk market participation in the ethiopian highlands

assessing the effectiveness of a technical assistance program the case of maize seed relief to vulnerable households in zimbabwe abstract the recent economic downturn in zimbabwe impoverished the majority of households to assist vulnerable rural households improve their food security the british department for international development implemented a seed relief program from 2003 2004 to 2005 2006 that emphasized recycling of maize open pollinated varieties opv using data collected from 597 households in six districts in 2006 this study assesses the effectiveness of the program in terms of its targeting of beneficiaries the flow of information from participating ngos to beneficiaries on the need to recycle the seeds and the level of recycling done at the end of the program the empirical results suggest that the targeting method participating ngos use inadvertently excludes relatively vulnerable households while including large proportions of relatively well endowed households in the program the choice of varieties to distribute is guided more by the ecological adaptability of available commercial seeds and less by preferences of beneficiaries notwithstanding the fact that seed selection information is critical in encouraging beneficiaries to recycle distributed seed not all of them received it in conclusion it may be stated that the program undoubtedly contributed to increased food productivity by vulnerable households but its overall effectiveness could have been enhanced through i the involvement of the beneficiaries in the choice of types of seed to be distributed ii better targeting of beneficiaries and iii improved information flow between ngos and beneficiaries

agroindustrialization through institutional innovation transaction costs cooperatives and milk market development in the east african highlands abstract some small holders are able to generate reliable and substantial income flows through small scale dairy production for the local market for others a set of unique transaction costs hinders participation cooperative selling institutions are potential catalysts for mitigating these costs stimulating entry into the market and promoting growth in rural communities trends in cooperative organization in east african dairy are evaluated empirical work focuses on alternative techniques for effecting participation among a representative sample of peri urban milk producers in the ethiopian highlands the variables considered are a modern production practice cross bred cow use a traditional production practice indigenous cow use three intellectual capital forming variables experience education and extension and the provision of infrastructure as measured by time to transport milk to market a tobit analysis of marketable surplus generates precise estimates of non participants distances to market and their reservation levels of the covariates measures of the inputs necessary to sustain and enhance the market policy implications focus on the availability of cross bred stock and the level of market infrastructure both of which have marked effects on participation the velocity of transactions in the local community and inevitably the social returns to agroindustrialization

modeling determinants of agricultural production cooperatives performance in iran the purpose of this article is to identify the fundamental factors that are key determinants in promoting effective operation of agricultural production cooperatives apcs a theoretical framework determinants of apcs performance was used to analyze the links between the webs of factors a survey method was used to collect data from two southern provinces in iran data were collected from 52 managers and 260 member farmers in 52 apcs using a stratified random sampling method it is concluded that the theoretical model can to a great extent predict the performance of apcs cooperative structure and government support factors are the most important factors explaining the performance of apcs also policy strategies need to focus on conditioning variables that affect the performance of apcs

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

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

modern input promotion in sub saharan africa insights from asian green revolution using case materials from four major cereal growing countries in asia bangladesh india indonesia and pakistan the article analyzes key aspects of agricultural input policies in asia results suggest that asian policies differ from the current wave of african input subsidy programs in three important ways i instead of focusing mostly on seed and chemical fertilizer input promotion in asia involved a package approach involving investments in agricultural rd ii farmers in three of four countries paid higher prices net taxed for fertilizer during the height of the green revolution suggesting that it was the profitability not the subsidy that was central to increasing fertilizer use and iii asian countries did not target input subsidies but given leakage and diversion estimates of targeted programs it is unclear whether targeting would have been more cost effective both continents have two challenges in common degradation of soil health and increasingly larger shares of public spending on input subsidies the first challenge calls for paying attentions to improving fertilizer use efficiency which is an achievable target with high pay off in the long run the other challenge is now a historical fact that is once introduced subsidies are hard to eliminate even if they no longer contribute to agricultural productivity growth

effect of off farm income on smallholder commercialization panel evidence from rural households in ethiopia this article investigates how off farm income affects crop output market participation decisions and marketed surplus of smallholder farmers in ethiopia a double hurdle model is estimated using three waves of panel data from the ethiopian rural household survey unobserved heterogeneity is controlled for using a correlated random effect procedure and potential endogeneity of explanatory variables using a control function approach the results show that off farm income has no significant influence on household crop output market participation however conditional on market participation additional off farm earnings negatively affect the marketed surplus this indicates that farmers use off farm earnings for consumption rather than for investment in agricultural production policy measures that promote rural investment may help increase returns to labor for land poor households participating in off farm work in the process of agricultural commercialization

why do small scale producers choose to produce under contract lessons from nontraditional vegetable exports from zimbabwe summary this article explores the motivations behind the decision of small scale producers to grow nontraditional vegetables under contract for export based on a survey of small scale producers in zimbabwe four factors are identified as motivating contracting namely market uncertainty indirect benefits e g knowledge acquisition income benefits and intangible benefits respondents are clustered according to the relative importance of these factors in their contracting decision four clusters are identified and related to the characteristics of these farmers including size of the farm amount of land devoted to export crops access to alternative markets and the proportion of family income derived from export crops the results suggest that there are systematic differences between farmers in their decisions to contract which needs to be recognized in contract design and management 2005 elsevier ltd all rights reserved

impact of global cotton markets on rural poverty in benin world cotton prices fell by about 40 over 2001 2002 focusing attention on the effect of subsidies for cotton growers in depressing world prices this paper combines farm survey data from benin with assumptions about the decline in farm level prices to estimate the direct and indirect effects of cotton price reductions on rural income and poverty in benin the results indicate that there is a strong link between cotton prices and rural welfare in benin a 40 reduction in farm level prices of cotton results in an increase in rural poverty of 8 points in the short run and 6 7 points in the long run under the assumptions of the partial input output model we estimate the multiplier to be in the range of 2 96 meaning that 1 us of reduced income by cotton growers results in a contraction of 2 96 us in overall income finally econometric analysis of the determinants of the demand for hired agricultural labor suggests that falling cotton prices will not greatly reduce labor demand since the labor intensity of cotton is similar to that of competing crops in benin overall the study demonstrates the impact of changes in world cotton prices on rural poverty in benin thus highlighting the likely negative effects of cotton subsidies in the united states and elsewhere on benin farmers

explaining a miracle intensification and the transition towards sustainable small scale agriculture in dryland machakos and kitui districts kenya abstract the transition to sustainable agriculture in tropical small scale farming has been discussed intensively since boserup published her theory on the role of population pressure as a leading factor bosemp s work challenged the malthusian approach to rural transformation recent evidence supports the boserup theory as applied to machakos district kenya this paper aims to establish how much of terracing is directly explained by population density increases as opposed to other district and village level variables by using a retrospective multivariate analysis in machakos and kitui districts kenya the findings suggest that variables such as the distance to major urban markets and the windfall profits from the coffee boom in the late 1970s are at least as important in explaining the investment in the quality of land in machakos and kitui districts

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

prospects for the socialist transition of agriculture in zimbabwe abstract in zimbabwe where a land reform programme is the chief socialist oriented domestic policy pursued by the government the issue of land is likely to remain the central political issue the government s resettlement and co operative programmes are likely to be jeopardized by the inherited agrarian legacy and fears of provoking white commercial farmers unless the state can intervene and acquire the unused and underutilized commercial farms any land available is likely to be poor and require high investment to facilitate resettlement to meet the needs and demands of the peasantry will require a political will and foresight which in the immediate future is likely to be constrained by a number of external and internal economic and political factors

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

raising offtake from cattle grazed on natural rangelands in sub saharan africa a transaction cost economics approach farmers in sub saharan africa are constrained by large transaction costs associated with marketing of their livestock however transaction costs are often not taken into account in the analysis of factors hampering the development of livestock marketing in this region this article empirically measures the influence of transaction costs on the offtake from cattle grazed on natural rangelands in uganda the study is based on the monitoring of 696 cattle transactions in three districts of uganda from august 2004 to august 2005 the estimated models suggest that proportional transaction costs represented by the state of roads distance to markets and time taken to reach the market are important variables constraining market participation in order to raise offtake from the national herd it is essential to explicitly address these costs one potential solution is collective action in marketing of livestock in which proportional and fixed transaction costs are reduced and shared among the group members

sulfur dioxide control in china policy evolution during the 10th and 11th five year plans and lessons for the future china s central government established national goals to reduce sulfur dioxide so2 emissions by 10 in both the 10th and 11th five year plan periods 2001 2005 and 2006 2010 respectively but the early policies were unsuccessful at reducing emissions emissions increased 28 during the 10th five year plan after adapting a number of policies and introducing new instruments during the 11th five year plan so2 emissions declined by 14 we examine the evolution of these policies their interplay with technical and institutional factors and capture lessons from the 11th five year plan to guide future pollution control programs we find that several factors contributed to achievement of the 11th five year plan so2 reduction goal 1 instrument choice 2 political accountability 3 emission verification 4 political support 5 streamlined targets and 6 political and financial incentives the approach integrated multiple policy instruments market based command and control and administrative instruments specific to the chinese context the evolution of so2 reduction policies and programs has implications for further so2 reductions from power plants and other sources as well as control of other atmospheric pollutants such as nitrogen oxides nox and carbon dioxide co2 in china

trade matters in the fight against poverty narratives perceptions and lack of evidence in the case of fish trade in africa two opposing views exist in the literature on the potential role that international fish trade plays in economic development while some claim that fish trade has a pro poor effect others denounce the negative effect of fish export on local populations food security and doubt its contributions to the macro economy in this paper we explore this debate in sub saharan africa our analysis did not find any evidence of direct negative impact of fish trade on food security neither did it find evidence that international fish trade generates positive pro poor outcomes this paper discusses the possible reasons for this apparent lack of development impact and highlights the unsupported assumptions underlying the current discourse about international fish trade we suggest that given lack of evidence for the development benefits of fish trade between africa and developed countries fisheries policy could consider support for regional africa to africa trade that meets the growing african demand for lower value fish means of overcoming barriers to intra african trade in fish are discussed

the economics of wheat research in developing countries the one hundred million dollar puzzle abstract currently 1 150 scientists are carrying out wheat improvement research in developing countries with an annual budget of around 100 million because of the recent reduction in agricultural research budgets this study marshalls evidence from 71 wheat research programs in 35 developing countries to address the following puzzle what is the optimal size type and location of wheat research programs in the developing world the analysis reveals that if research spillins are taken into consideration almost half of the wheat improvement programs in developing countries are inefficient the efficiency of wheat research in many national agricultural research systems can be increased by reducing the size of research programs consolidating state and federal research programs and shifting from wheat breeding research to capturing spillins from other countries and from the international maize and wheat improvement center cimmyt

search for nonwage job characteristics a test of the reservation wage hypothesis previous structural models of job search behavior have been based upon the reservation wage property this article provides estimates of a more general search model that nests models with the reservation wage property the estimates lead to rejection of the reservation wage property the model includes hours of work in the utility function but other nonwage job characteristics can be included as well an experiment based on the estimated parameters indicates that a significant proportion of job offers would be mistakenly predicted to be accepted or rejected under the restrictions implied by the reservation wage property

agricultural diversification and export promotion in sub saharan africa abstract declines in world commodity prices have emphasized the need in africa for diversification away from a few agricultural exports market reforms are not enough high transfer costs and imperfect factor markets imply that many consumer goods frequently including food staples are non tradables raising the possibility of major demand constraints in agriculture commodity specific zone specific and sequenced production and marketing policies are necessary to speed supply response of agricultural exports to market reforms then supply responsiveness must be increased for non tradable wage goods especially in non export producing zones to cope with new domestic demand created by export growth

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

food marketing and pricing policy in eastern and southern africa a survey abstract this article surveys the empirical record of grain marketing and pricing policy in eastern and southern africa over 1930 1995 the paper addresses five key issues with major implications for food policy throughout africa a why the anticipated supply response to market liberalization has not yet occurred b why the common assumption of state taxation of farmers to support a cheap food policy does not apply in most of the countries in the region c why the temporary successes of the state led approach to stimulating smallholder grain production were unsustainable d why the elimination of government food subsidies associated with market reform has not adversely affected consumers and e why the fiscal cost of the marketing systems at least initially worsened rather than improved after the reforms were implemented in most countries the key future challenges for marketing policy are how to develop coordinated and financially sustainable input finance and commodity marketing systems for raising productivity growth in smallholder agriculture while overcoming inherited agricultural dualism and how to mitigate the effects of food price instability in a cost effective manner

kenyan dairy policy change influence pathways and economic impacts summary marketing transporting processing and consuming dairy products contribute significantly to the livelihoods of many poor kenyan households this study analyzes the impact of recent research supporting policy changes to liberalize informal milk markets the study found that behavioral changes in dairy sector participants arising from the research evidence supported policy and regulatory changes led to an average 9 reduction in milk marketing margins and a significant increase in the number of licensed small scale milk vendors high welfare benefits arising from the policy change with a net present value of us 230 million are captured by consumers producers and milk vendors

new institutional arrangements for rural development the case of local woolgrowers associations in the transkei area south africa until recently smallholder farmers in the transkei area had very limited access to a profitable market outlet for their wool in response the south african wool industry built shearing sheds managed by a local association that sells directly to the brokers this article investigates the effect of joint wool marketing through the shearing shed on the farmers revenue from wool a three step regression model of the revenue from wool indicates that the farmers selling through the shearing shed obtain better financial results as compared to those who use alternative channels this analysis shows how new institutional arrangements may contribute to economic development

sulfur dioxide emission reduction of power plants in china current policies and implications abstract electricity generation by conventional fossil fuel power plants have caused severe environmental problems worldwide besides greenhouse gas emissions which has global impacts on the climate there are also pollutant emissions like sulfur dioxide which endanger the local environment in particular for developing countries who often highly rely on coal for power generation due to their resource endowment and the competitive costs of coal the issue of environment pollution caused by coal fired power plants is getting increasingly severe therefore various solutions should be combined and implemented to address the issue including environmental regulation and economic and financial incentives this study conducted an industry survey in 7 coal fired power plants in china to collect detailed data in the field to examine the costs and benefits of flue gas desulfurization currently coal fired power plants in china which install and properly operate flue gas desulfurization equipment can receive 15 yuan mwh premium tariff on top of their on grid tariffs however this study shows that this incentive is insufficient to cover the flue gas desulfurization costs of most of the sample plants more solutions both regulatory and market based should be considered to address this issue firstly under china s current regulated power plants dispatch scheme allocating generation hour based on the pollutant emission would provide strong incentive for sulfur dioxide mitigation secondly it is suggested to provide more supportive financial environment for flue gas desulfurization industry by fiscal supports diverse financing accesses and innovation financial and business models thirdly more environmental regulation tools such as emission cap and emission discharge fees should be set properly and examined carefully to optimize their impacts on economy society and environment finally the analysis and results of this study can also be applied in other fields such as denitration and dedusting of coal fired power plants

demand supply and willingness to pay for extension services in an emerging market setting although it may be wholly inappropriate to generalize the most important resource available to a subsistence household is the total amount of time that its members have available to spend in productive enterprises in this context services that minimize the time that it takes to perform productive activities are valuable to the household consequently the household is willing to relinquish quantities of other resources in exchange for quantities of the time saving service these simple observations motivate a search for the values that subsistence households place on time saving services this search is especially important when it is realized that extension services promote productivity enhance the surplus generating potential of the household and can as a consequence promote immersion into markets that are currently constrained by thinness and instability in this capacity extension visitation has the potential to overcome one of the principal impediments to economic development namely lack of density of market participation in this article we consider this issue in the context of a rich data set on milk market participation by small holder dairy producers in the ethiopian highlands

zimbabwe s maize based green revolution preconditions for replication abstract the green revolution was launched in 1960 in zimbabwe five years before it got underway in india since zimbabwe s green revolution was spearheaded by white commercial farmers however it was ignored by africa s new leaders in the 1960s as they experimented with state farms from moscow communal farms from china and land settlement schemes from israel at zimbabwe s independence in 1980 the new majority ruled government introduced a number of programs to help smallholders increase food and cash crop production drawing on a backlog of hybrid maize varieties expanded access to credit higher guaranteed government maize prices and marketing subsidies smallholders doubled maize production during 1980 1986 zimbabwe s maize based green revolution challenges those who allege that hybrid maize cannot compete with sorghum in low rainfall areas and that it is unsuitable for resource poor farmers because of the need to purchase new seed each year today virtually 100 of zimbabwe s maize area is under hybrids and short season hybrids are outcompeting other foodgrains in many low rainfall areas zimbabwe s biggest challenge is to develop cost effective marketing policies and institutions to sustain its maize based green revolution countries trying to replicate zimbabwe s success story should focus on fulfilling four interrelated preconditions political technological economic and institutional

policy options promoting market participation among smallholder livestock producers a case study from the phillipines we investigate the factors precipitating market entry where smallholders make decisions about participation a discrete choice about whether to sell quantities of products and supply a continuous valued choice about how much quantity to sell in a cross section of smallholders in northern luzon philippines in a model that combines basic probit and tobit ideas is implemented using bayesian methods and generates precise estimates of the inputs required in order to effect entry among the non participants we estimate the total amounts of cattle buffalo pig and chicken livestock input required to effect entry and compare and contrast the alternative input requirements to the extent that our smallholder sample may be representative of a wide and broader set of circumstances our findings shed light on offsetting impacts of conflicting factors that complicate the roles for policy in the context of expanding the density of participation

distributional effects of maize self sufficiency in zimbabwe implications for pricing and trade policy abstract maize self sufficiency has normally been an explicit policy goal throughout eastern and southern africa because of the perception that it could be achieved at prices below import parity and that it contributes to rural income growth however this analysis based on household survey data from zimbabwe and the results of an econometrically based simulation model indicates that a pricing policy geared towards maize self sufficiency would mainly benefit a small set of well off farmers and require either greater subsidies or higher prices to consumers many of whom are low income rural farmers in low rainfall areas the broader implications of this analysis are that even if the producer price needed for self sufficiency is below import parity the pursuit of food self sufficiency may inflate food costs and exacerbate rural and urban food insecurity compared to a self rellance policy involving imports

estimating workers marginal willingness to pay for job attributes using duration data this paper develops and applies a method for estimating workers marginal willingess to pay for job attributes when workers job choices are characterized by imperfect information and labor market search as an application this paper analyzes the job durations of white males using data from the national longitudinal survey youth cohort and the dictionary of occupational titles estimates of workers willingness to pay derived from the job duration model are compared with those derived from an hedonic wage model

maize is life malawi s delayed green revolution abstract the pattern of maize seed development in malawi demonstrates the importance of farmers capacity to articulate their interests through collective action and institutions despite the vital significance of maize as a wage good in malawi limited effective demand for maize seed research prolonged the period of technical stagnation analysis of the institutional factors shaping the demand for maize seed research complements previous work on malawi s political economy the supply of seed technology and adoption with implications for current political changes in that nation the importance of farmers organizations and state commitment to agricultural research in sub saharan africa

crossbred cow adoption and its correlates countable adoption specification search in sri lanka s small holder dairy sector considerable specification choice confronts countable adoption investigations and there is need to measure formally the evidence in favor of competing formulations this article presents alternative countable adoption specifications hitherto neglected in the agricultural economics literature and assesses formally their usefulness to practitioners reference to the left side of de finetti s 1937 famous representation theorem motivates bayesian unification of agricultural adoption studies and facilitates comparisons with conventional binary choice specifications such comparisons have not previously been considered the various formulations and the specific techniques are highlighted in an application to crossbred cow adoption in sri lanka s small holder dairy sector

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

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

increasing returns and market efficiency in agricultural trade abstract using detailed trader surveys in benin madagascar and malawi this paper investigates the presence of increasing returns in agricultural trade after analyzing margins costs and value added we find little evidence of returns to scale motorized transport is found more cost effective for large loads on longer distances but transporters appear to pool quantities from multiple traders margin rates show little relationship with transaction size personal travel costs are a source of increasing returns but the effect is small consequently total marketing costs are nearly proportional to transaction size working and network capital are key determinants of value added constant returns to scale in all accumulable factors working capital labor and network capital cannot be rejected this implies that policies to restrict entry into agricultural trade are neither necessary nor useful governments should focus instead on technological and institutional innovations to upgrade agricultural markets

measuring the damages of air pollution in the united states abstract this paper measures the damages due to emissions of air pollution in the united states an integrated assessment model is used to calculate the marginal damage associated with emitting an additional ton of pollution from nearly 10 000 sources in the u s the total damage produced by a source is the marginal damage of an emission its shadow price times the total tons emitted from a specific source adding total damages across all sources yields gross annual damages gad which is a green accounting parallel to gross domestic product gdp gad in 2002 varies between 71 billion and 277 billion 0 7 2 8 of gdp the range of values depends largely on the value of health and the concentration response function relating exposures to fine particulate matter pm 2 5 to adult mortality rates source location also matters urban emissions constitute 52 of total emissions by weight yet they cause nearly three quarters of the gad

statistical analysis and combination forecasting of environmental efficiency and its influential factors since china entered the wto 2002 2010 2012 abstract since china became a member of world trade organization wto its economy develops at a fast speed at the same time the environmental problem becomes more and more serious and increasingly affects economic development studying the factors that influence environmental efficiency has become an essential point in dealing with the relationship between economy and environment considering the differences in space and economic development among different districts this paper discusses the quantitative relationship among exports figure imports figure gdp per capita industrialization level fiscal decentralization and environmental efficiency of each chinese province by using statistical analysis furthermore this paper discusses differences among each district s influential factors from the perspective of spatial economics and makes combination forecast on the trend of environmental efficiency it also shows that the environmental efficiency of chinese provinces is generally at a low level in addition as the economic statuses of different provinces vary and the factors that influence environmental efficiency in different provinces also have significant differences each province should take certain measures to design the environmental protection policy in line with its local circumstance

optimal grain pricing and storage policy in controlled agricultural economies application to zimbabwe abstract maize pricing and storage policies of zimbabwe s grain marketing board are compared to those that would be optimal under certain objective function risk and risk aversion assumptions optimal producer prices and storage levels are found to be interdependent and to respond to prices at other levels of the marketing chain the ideal maize reserve stock increases with uncertainty over import transportation costs a factor to consider in light of the threat of south african sanctions but at a reasonable risk aversion level optimal reserves still are much lower than those presently held by the board

state intervention for food price stabilisation in africa can it work abstract although its arguments may have more general applicability this paper discusses the desirability and options for the stabilisation of staple food prices principally in eastern and southern africa it addresses three broad questions i why is stabilisation of food grain prices desirable ii what is technically feasible and iii can the governance and trade issues thrown up by suggested mechanisms be solved it considers a number of options for price stabilisation assessing the strengths and weaknesses of each and suggesting situations in which each may be appropriate

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

indian farmers valuation of yield distributions will poor farmers value pro poor seeds abstract potential poverty traps among the rural poor suggest a need to reduce poor farmers vulnerability by stabilizing crop yields and limiting yield losses advances in biotechnology will help address this need directly with crops that tolerate climate fluctuation or resist biotic stresses evaluating ex ante how farmers will value these pro poor seeds is important for delivery design but also challenging this paper describes an experimental economic approach to understanding farmers valuation of such seeds using data from a survey and experiment i assess indian farmers valuation of changes in the mean variance and skewness of payoff distributions these farmers value increases in expected value but seem indifferent about higher moment changes in payoff distributions farmer traits such as wealth and risk exposure affect their valuation of these changes only mildly while various limitations to the experimental approach must qualify practical implications of these findings the experiment demonstrates the viability of conducting valuation experiments with open ended questions in developing countries

urban bias a fresh look focusing on non conforming cases the articles in this special issue abandon the method of stylised facts and highlight instead variation over space and time in so doing they detect errors of commission and omission in the earlier literature on urban bias they call for a focus on the economic role of political institutions the political role of markets for assets and the political significance of technical change

maize food self sufficiency and policy in east and southern africa abstract in recent years maize has become a major food staple in the east and southern african region national average yields of maize remain low and yield gains are generally below population growth rates agricultural policy particularly maize pricing marketing and trade is examined and it is noted that despite an objective of maize self sufficiency many countries in the region continue to face erratic supplies finally a brief look is taken at the technologies available for maize and at those groups of smallholders who are unable to meet their annual household food requirements

post uruguay round price linkages between developed and developing countries the case of rice and wheat markets the uruguay round agreement on agriculture attempted to lower distortions in global agricultural markets however the significant fall in commodity prices in the late 1990s may have reduced the incentives for both developed and developing countries to better integrate into world markets this study analyzes price linkages and adjustment between developed and developing countries during the post uruguay round period prices of two key commodities long grain rice and medium hard wheat are assembled for major exporters and producers results of multivariate cointegration analysis suggest partial market integration between developed and developing countries in the post uruguay round period developed countries are found to be price leaders in these two markets and in most cases changes in their prices have relatively large impacts on those of the developing countries developing countries e g vietnam and argentina have faced considerable price adjustment due to changes in the developed countries prices

building african scientific capacity for agricultural development abstract during africa s first two decades of independence from 1960 to 1980 priority was given to increasing the size of national extension services because it was assumed that technology could be imported from industrial countries and the international agricultural research centers over the past decade donors have turned their attention to assisting national agricultural research systems nars but many nars are performing poorly and are faced with a high turnover of scientific staff and inadequate operating budgets moreover the present donor financed project by project and country by country approach to building african scientific capacity is seriously flawed this paper examines africa s agricultural research history over the past six decades and draws lessons for strengthening national and regional agricultural research systems over the coming 30 years

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

south african land policy the legacy of history and current options abstract the highly dualistic farm structure of south africa and the low productivity of native african farmers have been the result of systematic distortions in land allocation output markets the provision of infrastructure agricultural credit and services the dualistic structure did not emerge because of genuine economies of scale in the large commercial sector other countries in latin america and africa that once supported a dualistic farm size structure through similar distortions have either implemented large scale land reforms or have experienced decades of peasant revolts and civil war the paper compares these international experiences to south africa and outlines judicial and market assisted approaches to south african land reform

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

environmental impacts of technological change in bangladesh agriculture farmers perceptions determinants and effects on resource allocation decisions this article measures the impact of modern technology adoption in raising farmers environmental awareness and the impact of farmers environmental awareness on resource use by utilizing survey data from 21 villages in three agro ecological regions of bangladesh the econometric analysis is based on the application of the tobit model explaining farmers environmental awareness in the first stage and a profit function examining environmental awareness and resource use relationships in the second stage results reveal that the level and duration of involvement with modern technology raises farmers environmental awareness and that farmers environmental awareness reduces resource use including chemicals farmers who are aware of the adverse environmental impacts of modern agricultural technology use lower amounts of all inputs in order to avoid further environmental damage therefore efforts to raise farmers environmental awareness are expected to enhance intangible benefits accruing from a relatively less chemical intensive environment

a model of layoff search and job choice and its estimation a labor market model of search and transitions is analyzed where certain jobs carry layoff prospects and others do not the dynamic value functions are solved for reservation wages for searchers with a choice between these jobs for the laid off worker the wage at the prior job emerges as an important determinant of the optimal search strategy similarly prospect of layoff is an important consideration for permanently separated workers during search conditioning on the nonparametric estimates of the reservation wages the model is estimated using data from the employment opportunities pilot project survey copyright 1992 by mit press
