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

targeting capital a cultural economy approach to understanding the efficacy of two anti genetic engineering movements in the late 1990s the british anti genetic engineering ge movement effectively closed britain s market for genetically modified foods while the u s anti ge movement had a negligible impact in seeking to explain the different outcomes of these similar social movements the authors draw upon the global commodity chains gcc literature to extend the understanding of the economic and industry related openings and closures social movements face as they seek to promote social change this analysis not only illustrates the importance of economic structures and organization for movement outcomes but also shows how the economic sphere is culturally constituted in this fashion it broadens the social movement literature s understanding both of the way that political economy matters to movement efficacy and of the way that cultural processes infuse the economic sphere the study advances the gcc literature by showing how gccs are cultural as well as economic constructs

did unilateral divorce laws raise divorce rates a reconciliation and new results application of the coase theorem to marital bargaining suggests that shifting from a consent divorce regime to no fault unilateral divorce laws should not affect divorce rates each iteration of the empirical literature examining the evolution of divorce rates across us states has yielded different conclusions about the effects of divorce law liberalization i show that these results reflect a failure to jointly consider both the political endogeneity of these divorce laws and the dynamic response of divorce rates to a shock to the political regime taking explicit account of the dynamic response of divorce rates to the policy shock i find that liberalized divorce laws caused a discernible rise in divorce rates for about a decade but that this increase was substantially reversed over the next decade that said this increase explains very little of the rise in the divorce rate over the past half century both administrative data on the flow of new divorces and measures of the stock of divorcees from the census support this conclusion these results are suggestive of spouses bargaining within marriage with an eye to their partner s divorce threat

the impact of legislation on divorce a hazard function approach the paper examines the impact of the introduction of no fault divorce legislation in australia the approach used is rather novel a hazard model of the divorce rate is estimated with the role of legislation captured via a time varying covariate the paper concludes that contrary to us empirical evidence no fault divorce legislation appears to have had a positive impact upon the divorce rate in australia

collective learning in global diffusion spreading quality standards in a developing country cluster this research analyzes how foreign organizational practices diffuse among indigenous enterprises in a developing economy it highlights the collective knowledge building process as central for understanding diffusion based on a longitudinal case study of a cluster of dairy producers in nicaragua a representative low income country it looks at cross border diffusion in conditions that differ significantly from advanced economies the current literature that highlights institutional pressures driving global spread of practices has limits for capturing a significant dynamic caused by increased integration of markets and production by focusing on production organization and practices in a late developing context this paper explains the intertwined process of spreading new standards and changing existing local practices by elaborating the relationship among building collective capabilities learning and standards diffusion this study enriches current views on institutional effects and adds to the practice based literature as well as to the work on developing economy firms in organizational research

is there a pilot in the chain identifying the key drivers of change in the fresh pineapple sector high value export oriented agriculture is today considered as a means of integrating smallholders into the world economy this paper examines the geographic and organisational changes that have taken place in the fresh pineapple sector over the past 50 years we begin with a historical analysis of the changes in leadership among producer countries namely the dethroning of cote d ivoire by costa rica we show that this geographical shift has been accompanied by massive organisational changes the pineapple sector is increasingly driven by large downstream actors who derive their power from the ability to impose their definition of quality to the whole chain and from economies of scale and scope although varietal innovation plays a key role throughout the period commercial and logistical innovation are of increasing strategic importance however because of the constraints imposed by the concerned supply chains small farmers risk being excluded or marginalized

domestic violence and divorce law when divorce threats become credible the cost of divorce influences the bargaining position of spouses and thus their behavior within the marriage this study takes advantage of a major and unexpected reduction in divorce costs in spain to estimate the causal effects on domestic violence results suggest a 30 decline in spousal conflict as a consequence of the reform spousal violence is found to have decreased among couples who remained married after the modification in the law which suggests an important role for changes in bargaining within the marriage when divorce becomes a more credible cheaper option

the influence of proximity to market on bean producer prices in nicaragua transport costs are an important determinant of smallholder welfare in developing countries in particular transport costs influence the prices that smallholders receive for their produce we propose a simple way of quantifying this influence taking the example of bean producers in nicaragua we employ a hedonic price model to estimate the effects of a smallholder s proximity to markets on the prices that he she receives while controlling for other factors such as the volume and quality of beans sold we find that on average each additional minute of travel time reduces farm gate prices by 2 5 cents per quintal based on these results the annual income from bean sales of the average smallholder in our sample would increase by between 24 and 110 usd if travel time to markets were reduced by 25 estimates of this nature can make an important contribution to cost benefit assessments of infrastructure investments

marriage and divorce reply in the popular press and among policymakers the effect of no fault divorce laws on divorce rates remains an issue see e g new york times 23 july 1991 in my 1986 article in this review i show that the adoption of one form of no fault divorceunilateral divorce does not lead to a significant increase in divorce rates the theoretical model that is consistent with this empirical evidence would imply that the new law does not decrease the costs of divorce it merely redefines which party has the right to terminate the marriage

the latte revolution regulation markets and consumption in the global coffee chain abstract coffee is a truly global commodity and a major foreign exchange earner in many developing countries the global coffee chain has changed dramatically as a result of deregulation new consumption patterns and evolving corporate strategies from a balanced contest between producing and consuming countries within the politics of international coffee agreements power relations shifted to the advantage of transnational corporations a relatively stable institutional environment where proportions of generated income were fairly distributed between producing and consuming countries turned into one that is more informal unstable and unequal through the lenses of global commodity chain analysis this paper examines how these transformations affect developing countries and what policy instruments are available to address the emerging imbalances

what lies between market and hierarchy insights from internalization theory and global value chain theory in this paper we suggest that internalization theory might be extended by incorporating complementary insights from gvc theory more specifically we argue that internalization theory can explain why lead firms might wish to externalize selected activities but that it is largely silent on the mechanisms by which those lead firms might exercise control over the resultant externalized relationships with their gvc partners we advance an explanation linking the choice of control mechanism to two factors power asymmetries between the lead firms and their gvc partners and the degree of codifiability of the information to be exchanged in the relationship

food value chain transformations in developing countries selected hypotheses on nutritional implications we examine how the transformation of food value chains fvcs influence the triple malnutrition burden undernourishment micronutrient deficiencies and over nutrition in developing countries we propose a fvc typology modern traditional modern to traditional and traditional to modern that takes into account the participants the target market and the products offered next we propose selected hypotheses on the relationship between each fvc category and elements of the triple malnutrition burden the primary finding is that the transformation of fvcs creates challenges and opportunities for nutrition in developing countries for example modern fvcs may increase over nutrition problems and alleviate micronutrient deficiencies for urban people with relatively high incomes however they have little nutritional impacts among rural residents and urban poor people who primarily depend on traditional fvcs to access adequate quantities of calories and micronutrients in addition modern food manufacturers are leveraging traditional distribution networks modern to traditional fvcs substantially increasing access to low priced processed packaged foods in rural areas and low income urban neighbors with mixed impacts on the triple burden of malnutrition further research should focus on the influence of fvc transformation on reduction of micronutrient deficiencies on modeling demand substitution effects across food categories and the attendant policy implications for malnutrition

tobin s q and the importance of focus in firm performance using tobin s q as a measure of performance we seek to estimate the relative importance of industry focus and share effects in determining firm performance our methods are analogous to those of richard schmalensee and like him we find that industry effects account for the majority of the explained variance however we also find that firm effects exist in the form of focus effects that is narrowly diversified firms do better than widely diversified firms we interpret this finding as consistent with profit maximization by firms with different factor endowments

economics and politics of food standards trade and development standards have played an important role in food trade for a very long time their rapid growth in recent years has triggered vigorous debates on their impacts on international trade and development with many arguing that standards are non tariff barriers to trade and that standards are marginalizing the poor i present conceptual frameworks and review empirical evidence on the equity and efficiency effects and the political economy of standards models which incorporate essential aspects of standards yield complex theoretical results and nuanced conclusions careful empirical analyses support such nuanced arguments and find complex effects for trade standards can create welfare gains but also involve rent redistribution which induces lobbying by interest groups to set the standards at their preferred level this makes it difficult to distinguish socially desirable standards from those resulting from political rent seeking for development it is crucial to explicitly account for a the endogeneity of the institutional organization of value chains and b both smallholder contracting and employment creation on large scale farms when considering the impact of standards on development and poverty

marriage and divorce changes and their driving forces the family is not a static institution in recent decades marriage rates have fallen divorce rates have risen and the defining characteristics of marriage have changed the economic approach to the family seeks to explain these trends by reference to models that can also explain how and why families form gary becker s 1981 treatise on the family proposed a theory based on production complementarities in which husband and wife specialize in the market and domestic spheres respectively production complementarities also arise in the production and rearing of one s own children however production complementarities at least as initially described are decreasingly central to modern family life increased longevity and declining fertility mean that most of one s adult life is spent without one s own children in the household also the rise in marital formation at older ages including remarriage means that many families form with no intention of producing children moreover increases in female labor force participation suggest that household specialization has either declined or at least taken on a different meaning these changes have come about as what is produced in the home has been dramatically altered both by the emergence of labor saving technology in the home and by the development of service industries that allow much of what was once provided by specialized homemakers to be purchased in the market the availabil

diversification into horticulture and poverty reduction a research agenda summary horticultural produce and processed products from the developing world are becoming increasingly popular both in domestic and in international markets global production and exports are rising steadily however yield increases have been smaller than area growth and have been negligible or even negative in the least developed countries while experience shows that horticulture can offer good opportunities for poverty reduction because it increases income and generates employment care must be taken that small and poor farmers are not excluded from the opportunities in these market sectors in this article we argue that development agencies must put more emphasis on horticultural research and development especially in the following priority areas genetic improvement safe production systems commercial seed production postharvest facilities and the urban peri urban environment

divorce law reforms and divorce rates in the usa an interactive fixed effects approach this paper estimates the eects of unilateral divorce laws on divorce rates from a panel of state level divorce rates we use the interactive xed eects model to address the issue of endogeneity due to the association between cross state unobserved heterogeneity and divorce law reforms we document that earlier studies in the literature do not fully control for unobserved heterogeneity and result in mixed empirical evidence on the eects of divorce law reforms our results while reconciling these conicting results suggest that divorce law reforms have positive eects on divorce rates but the magnitude and duration of the eects

law property and marital dissolution this paper challenges the view that legal rights are not important in affecting whether people divorce but it puts as much emphasis on property rights given for example by the law on alimony as on dissolution rights in the united states the paper sets out two stylised models of marriage and examines the consequences of fuller compensation for economic sacrifices made during marriage if the dominant economic issue in a marriage is who undertakes household tasks then a law giving fuller compensation makes divorce more likely if the dominant issue is child custody divorce is less likely excerpt

an inquiry into the state s role in marriage abstract i view state intervention in marriage as a means of avoiding large transaction costs between men and women i define transaction costs as the resources devoted towards wealth capture and protection and i argue that they are high within a cohabitational contract state intervention is successful because marriage creates incentives that make private enforcement relatively costly and because marriages tend to be homogeneous i test the hypothesis by examining state responses to changing divorce laws and i find that these actions are consistent with the state increasing the social value of marriage by mitigating transaction costs

public private partnerships and collective action in high value fruit and vegetable supply chains accessing developed country food markets entails meeting stringent food safety requirements food retailers impose protocols relating to pesticide residues field and pack house operations and traceability to enable smallholders to remain competitive in such a system new institutional arrangements are required in particular public private partnerships can play a key role in creating farm to fork linkages that can satisfy market demands for food safety while retaining smallholders in the supply chain furthermore organized producer groups monitoring their own food safety standards through collective action often become attractive to buyers who are looking for ways to ensure traceability and reduce transaction costs this paper compares the ways in which small producers of fruits and vegetables in kenya and india have coped with increased demands for food safety from their main export markets

reforms globalization and endogenous agricultural structures in this paper i draw lessons from two quasi natural experiments the transition process in former communist countries and the rapid globalization of food chains on the optimality of farms and agricultural structures more generally i argue that a the farm structures that have emerged from the transition process are much more diverse than expected ex ante b this diversity is to an important extent determined by economic mechanisms which are influenced by initial conditions eg technology and reform policies c non traditional farm structures have played an important role during transition since they were optimal to address the specific institutional and structural constraints imposed by the transition process d there is more diversity than often argued in the farms that are integrated in global food chains e endogenous institutional contracting innovations in food chains may lock existing farm structures in a long run institutional framework and f indicators based on farm structures are not a good measure of welfare effects of the globalization of food chains

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

the impact of interfirm relationships on investment evidence from the polish dairy sector abstract financial constraints and credit market imperfections are a major constraint on investment growth and poverty reduction in transition and developing countries this paper analyses the impact on investments of financial assistance programs as part of interfirm relationships our empirical evidence is based on a two stage survey methodology qualitative evidence on dairy companies assistance programs was gathered in the first stage through in depth interviews at the level of the dairy companies quantitative data on 290 milk producing rural households in poland was collected through a random survey in the second stage the empirical analysis shows that dairy companies have played an important role in financial assistance in particular for dairy specific investments in addition they had an important indirect impact on farm activities and investments through feed supply and loan guarantee programs

spurred to upgrade a review of triggers and consequences of industrial upgrading in the global value chain literature summary the global value chains gvc literature intervenes in today s challenging development context by focusing on the means by which developing country industries can upgrade their market positions and outcomes for workers yet while this literature has produced hundreds of rich empirical case studies there has to date been no attempt to systematically analyze this case literature for lessons regarding the antecedents and consequences of the key outcome of upgrading this paper undertakes a systematic analysis of a representative sample of 45 case studies of primary product and light manufacturing industries in developing countries these studies were coded for factors involved in initiating and sustaining upgrading processes the results of upgrading and the role of local institutions in these processes we find that contrary to the major assumptions of the literature advanced country buyers are not the main force in the initiation of industrial upgrading rather in most cases developing country firms initiate upgrades when pushed by shocks of market vulnerability usually produced by state policies that force them to seek to change their status quo operations once initiated upgrading processes can produce a wide spectrum of results from little to no advancement in market position treadmilling to vaulting to the forefront of a global industry leaps forward on the basis of the sources of learning present in the local institutional environment such as state agencies and business associations we also identify conditions under which state participation in upgrading processes can lead to increased local institutional capacity together these findings suggest a framework for upgrading that we refer to as an induced search model this model has important implications for future research on the dynamics of industrial upgrading in developing countries techniques of state intervention and processes of mutually supportive learning between actors in the public and private sector

private voluntary standards in the food system the perspective of major food retailers in oecd countries abstract the paper examines the main economic and institutional incentives which have driven major oecd food retailers in their use of private voluntary standards and discusses their growing role in shaping the agri food system it is based on interviews with quality and safety directors of major oecd retailers and a brief survey of retailers actual buyer practices though not all retailers are included these firms account for over 70 of retail food sales in oecd countries we find that the growing voice of civil society changing legal and institutional frameworks increased market concentration and buying power as well as their integration with financial markets has provided the setting for development of private standards while food safety and quality standards are seen as key to maintaining and improving reputation as well as against legal liabilities additional standards such as labour environmental and animal welfare are also gaining ground as strategies for customer loyalty and market shares the grass roots retailer move in the harmonization of food safety standards is seen as an initial step towards a global approach to managing the food system with harmonization of other standards likely in the future given their buyer power these developments can be viewed as a way of governing the food system and will be important for both oecd and non oecd food and agricultural sector evolution in the coming years

diversification ricardian rents and tobin s q according to prevailing theory firms diversify in response to excess capacity of factors that are subject to market failure by probing into the heterogeneity of these factors we develop the corollary that firms that elect to diversify most widely should expect the lowest average rents an empirical test with tobin s q as the measure of rents is consistent with this theory

understanding developing country strategic responses to the enhancement of food safety standards this paper explores the competing concepts of standards as barriers and standards as catalysts in the context of food safety standards in international trade in agricultural and food products through a review of existing evidence of the impact of food safety standards on developing country exports of agricultural and food products and the results of a series of country and product specific case studies it is suggested that food safety standards can act as both a barrier to trade and the basis of competitive positioning for developing countries in international markets this suggests that broad conclusions about the trade effects of food safety standards on developing countries are problematic rather the level and ways in which agricultural and food exports are impacted can be product country standard and even firm specific

unilateral divorce versus child custody and child support in the u s this paper explores the response of the divorce rate to law reforms introducing unilateral divorce after controlling for law reforms concerning the aftermath of divorce which are omitted from most previous studies we introduce two main policy changes that have swept the us since the late 1970s the approval of the joint custody regime and the child support enforcement program because those reforms affect divorce decisions by counteracting the reallocation of property rights generated by the unilateral divorce procedure and by increasing the expected financial costs of divorce it is arguable that their omissions might obscure the impact of unilateral divorce reforms on divorce rates after allowing for changes in laws concerning the aftermath of divorce we find that the positive impact of unilateral divorce reforms on divorce rates does not vanish over time suggesting that the coase theorem may not apply to changes in divorce laws supplemental analysis developed to examine the frequency of permanent shocks in us divorce rates indicates that the positive permanent changes in divorce rates can be associated with the implementation of unilateral divorce reforms and that the negative permanent changes can be related to the law reforms concerning living arrangements in the aftermath of divorce this seems to confirm the important role of these policies in the evolution of divorce rates

labour leverage in global value chains the role of interdependencies and multi level dynamics the global segmentation of production and distribution has resulted in highly complex global value chains gvcs where vertical and horizontal dynamics are equally important in determining working conditions and providing points of leverage for labour borrowing notions of multi level governance we propose an analytical framework for describing and explaining success and failure of labour agency when attempting to improve working conditions along gvcs our starting point is that the high complexity of gvcs and the absence of a global overarching authority have been balanced by the emergence of governance mechanisms of different forms and at different levels an assessment of these mechanisms which emphasize process over institutions reveals how different types of interactions and interdependencies along gvcs impact on labour s use of power we argue that in order to fully situate labour agency within governance debates any future research agenda needs to be driven by micro level bottom up approaches

dynamics of smallholder participation in horticultural export chains evidence from ecuador we study the dynamics of smallholder participation in export value chains focusing on the example of small scale broccoli producers in the highlands of ecuador combining cross sectional data from a household survey with 11 year longitudinal data on export market transactions we explain the hazards of dropping out of a high value export chain we apply a multispell cox duration model that allows us to consider multiple entries and exits from the supply chain we also provide evidence on the welfare impacts associated with participation the results suggest that small scale farmers exit from the export sector is accelerated by high transaction risks experienced in the past while we find no particular evidence for the exclusion of small scale farmers from the export sector we do find that poorer households and female headed households tend to drop out faster especially as long as the sector is still prospering finally when considering welfare effects we do not find evidence that participation translates into tangible benefits for broccoli farmers we discuss some measures that could help improve the long term sustainability of smallholder integration in high value chains

the hidden middle the quiet revolution in the midstream of agrifood value chains in developing countries the food security debate has focused largely on the farm sector and on trade relatively neglected or hidden from mainstream debate are the middle segments processing logistics wholesale of agrifood value chains in developing countries and yet this midstream forms 30 40 per cent of the value added and costs in food value chains the productivity of the midstream is as important as farm yields for food security in poor countries the article shows that over the past several decades the middle segments have transformed quickly and surprisingly with a huge volume expansion a proliferation of small and medium enterprises smes but also concentrating and multinationalizing in some places and products with technology change characterized by capital led intensification and with the incipient emergence of branding and labelling and packaging of new organizational arrangements in procurement and marketing interfaces with farmers and retailers and of private standards and contracts economic policies of market and foreign direct investment fdi liberalization commercial and business climate regulations hard and soft infrastructure investment and food safety laws have paved the path to the expansion and shaped the transformation of the important midstream segment of food value chains

developing technological capabilities in agro industry ghana s experience with fresh pineapple exports abstract this article examines the emergence and trajectory of a new agro industry in ghana the pineapple export industry using the technological capabilities approach it explains the limited expansion of the industry and its declining competitiveness in the face of new competition by looking at how ghanaian exporters developed technological capabilities initially and the incentives and disincentives to building on those capabilities the article argues that at the heart of the industry s crisis was an inability to further develop technological capabilities the crisis had systemic features that have broader implications for developing new agro industries in ghana as well as other african countries

small farmers and big retail trade offs of supplying supermarkets in nicaragua summary in nicaragua and elsewhere in central america small scale farmers are weighing the risks of entering into contracts with supermarket chains we use unique data from cooperatives supplying supermarkets to study the effect of supply agreements on producers mean output prices and price stability we find that prices paid by the domestic retail chain approximate the traditional market in mean and variance while mean prices paid by walmart are significantly lower than the traditional market however the walmart contract is found to systematically reduce price volatility we find some evidence however that farmers may be paying too much for this contractual insurance against price variation

strategic use of private standards to enhance international competitiveness vegetable exports from kenya and elsewhere abstract the paper examines how european retailers are using private standards for food safety and quality as risk management and competitive tools and the strategic responses of leading kenyan and other developing country supplier exporters to such standards despite measures to harmonize a single market the european fresh produce market is very diverse in terms of consumer preferences structural dynamics and attention to and enforcement of food safety and other standards leading kenyan fresh produce suppliers have re positioned themselves at the high end including high care segments of the market precisely those that are most demanding in terms of quality assurance and food safety systems an array of factors have influenced this strategic positioning including relatively high international freight costs the emergence of more effective competition in mainstream product lines relatively low labor costs for produce preparation and strong market relationships with selected retail chains to succeed in this demanding market segment the industry has had to invest substantially in improved production and procurement systems upgraded pack house facilities and quality assurance food safety management systems

governance of global value chains in response to food safety and certification standards the case of shrimp from vietnam summary we use global value chain gvc theory to understand governance of vietnam s shrimp farming industry we describe this gvc as buyer driven with important food safety standards imposed by governments of importing countries and new certification systems promoted by nongovernmental organizations ngos governance relations are clear between governments in importing countries and vietnam and between importers and ngos governance relations become more fragmented further down the chain where large numbers of small scale producers and traders operate this fragmentation may adversely affect access to the most lucrative markets and have the unanticipated effect of marginalizing small scale farmers and traders

the effect of joint custody on family outcomes since the 1970s almost all us states have introduced a form of joint custody after divorce i analyze the causal effect of these custody law reforms on different family outcomes my identification strategy exploits the different timing of reforms across the us states estimations based on state panel data suggest that the introduction of joint custody led to an increase in marriage rates an increase in overall fertility including a shift from nonmarital to marital fertility and an increase in divorce rates for older couples accordingly female labor market participation decreased further male suicide rates and domestic violence fell in treated states the empirical evidence is consistent with the hypothesis that joint custody increased the relative bargaining power of men within marriage

the global business revolution the cascade effect and the challenge for firms from developing countries the global business revolution since the 1980s has witnessed an unprecedented degree of industrial consolidation and concentration of business power at a global level firms with powerful globally recognised technologies and or brands constitute the systems integrators at the apex of extended supply chains this paper examines the supply chains in four different sectors aerospace telecommunications automobiles and beverages it finds that these sectors have striking similarities in the way in which the core systems integrators have stimulated industrial concentration across the whole supply chain this cascade effect has profound implications for firms from developing countries in catching up at the firm level

yours mine and ours do divorce laws affect the intertemporal behavior of married couples divorce laws establish spouses individual property rights over household resources and determine when divorce is allowed this paper examines how such laws inuence the intertemporal behavior and the welfare of u s married couples i build a model of household choice about consumption labor supply and divorce under multiple divorce law regimes and i estimate it using exogenous variation in u s divorce laws from the 1970s to the 1990s couples responded to equal division of property and unilateral divorce by increasing tangible assets up to 19 which suggests the presence of a strong income eect for the primary earner and by reducing female employment by over 5 percentage points because the threat of divorce granted additional bargaining power to married woman the bargaining weight of women implied by these responses in the model corresponds to a third of the weight of men this indicates that equal division of assets beneted women when it was

small farmers ngos and a walmart world welfare effects of supermarkets operating in nicaragua despite more than a decade of ngo and government activities promoting developing world farmer participation in high value agricultural markets evidence regarding the household welfare effects of such initiatives is limited this paper analyzes the geographic placement of supermarket supply chains in nicaragua between 2000 and 2008 and uses a difference in difference specification on measures of supplier and non supplier assets to estimate the welfare effects of small farmer participation though results indicate that selling to supermarkets increases household productive asset holdings they also suggest that only farmers with advantageous endowments of geography and water are likely to participate

sustainability governance of chains and networks a review and future outlook this paper reviews the extent to which sustainability governance has been integrated into the literature on sustainable chains and networks the analysis brings together four main approaches to chains and network studies supply chain management scm global commodity chains gcc global value chains gvcs and global production networks gpns to examine how and the extent to which sustainability and sustainability governance are conceptualised and incorporated into their analytical frameworks the results point to a shift in this combined literature from conceptualising the formation of global chains and networks as sites of inequality under conditions of globalisation towards a renewed vision on the potential of chains as a site for social and environmental reform overall however we conclude that the literature on global chains and networks has not adequately conceptualised distinct modes of sustainability governance in response we offer an amended typology for identifying how firm and non firm actors govern sustainability in chains of chains and through chains in globalised commodity production and consumption the paper finishes with an exploration of the research frontiers challenges and continuing potential of chain and network studies to understand the governance of sustainability and a call for further academic debate on the kinds of integrated governance arrangements necessary for future sustainability reform through hybridised public private economic practice

horticultural exports female wage employment and primary school enrolment theory and evidence from senegal abstract in this paper we analyse the indirect effects of the boom in horticultural exports in senegal on child schooling the export boom has caused a dramatic increase in female off farm wage employment which led to increased female bargaining power in the household we investigate the causal effect of female wage income on primary school enrolment we develop a collective household model with endogenous bargaining power to show that if women have higher preferences for schooling than men the impact of female wage income on school enrolment will be the result of a positive income effect a negative labour substitution effect and a positive empowerment effect we address the question empirically using original household survey data from senegal we use different econometric techniques and show that female off farm wage income has a positive effect on primary school enrolment for both boys and girls and that female empowerment is specifically important for the schooling of girls our results imply that the horticultural export boom in senegal has indirectly contributed to the second and third millennium development goals of universal primary education and elimination of gender disparities in primary education

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

global value chains large scale farming and poverty long term effects in senegal this paper presents panel data evidence on the impact of expansion of global value chains and large scale export oriented farms in developing countries over almost a decade we estimate the income effects of wage employment on large scale farms in the horticultural export sector in senegal using data from two survey rounds covering a seven years period of rapid expansion of the sector we estimate average income effects as well as heterogeneous income effects using fixed effects and quantile fixed effects regressions we find that poverty and inequality reduced much faster in the research area than elsewhere in senegal employment in the horticultural export sector is associated with higher household income and the income effect is strongest for the poorest households expansion of the horticultural export sector in senegal has been particularly pro poor through creating employment that is accessible and creates substantial income gains for the poorest half of the rural population these pro poor employment effects contrast with insights in the literature on increased inequality from rural wage employment

welfare effects of vegetable commercialization evidence from smallholder producers in kenya we investigate whether smallholder horticultural commercialization is able to as often stipulated reduce poverty in developing countries with the help of panel household survey data from kenya we find evidence for a positive association between vegetable commercialization and household welfare even when controlling for unobserved heterogeneity across households interestingly the effect differs depending on which market vegetables are being produced for commercialization through the export market is consistently positively associated with income but not wealth while there is some limited evidence for commercialization through the domestic market channel being positively related to welfare measured by asset holdings and income depending on the specification

in the market but not of it fair trade coffee and forest stewardship council certification as market based social change summary this paper discusses two well known market based social change initiatives fair trade coffee and forest stewardship council certification which harness market forces to pursue social and environmental objectives a serious challenge for both is to operate in the conventional market without undermining their original objectives a global commodity chain analysis approach is combined with insights from economic sociology embeddedness theory to explore the social cultural and organizational factors shaping the initiatives governance structures both initiatives are seen to move along opposite organizational trajectories but face similar pressures from conventional market logics practices and dominant actors a preliminary framework is proposed for comparative assessment focusing on distribution of benefits how conventional market institutions may be questioned and how internal governance manages diverse stakeholder interests and influence

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

replication in empirical economics the journal of money credit and banking project this paper examines the role of replication in empirical economic research it presents the findings of a two year study that collected programs and data from authors and attempted to replicate their published results the research provides new and important information about the extent and causes of failures to replicate published results in economics the findings suggest that inadvertent errors in published empirical articles are a commonplace rather than a rare occurence copyright 1986 by american economic association

female earnings and the divorce rate a simultaneous equations model economists have contributed a great deal of research both theoretical and empirical to the study of marital formation and dissolution many empirical examinations of marriage and divorce rates exist based on becker s seminal contributions to the literature all of these divorce studies are single equation models with female earnings assumed exogenous as discussed by becker 1981 however causality may run in the opposite direction as well the divorce rate may influence female earnings this paper estimates a simultaneous equations model in which divorce rates and female earnings are the jointly endogenous variables data are by state for 1960 1970 1980 and 1990 the state wide divorce rate equation is an extension of waters and ressler 1999 and the specification of a state wide earnings equation follows standard human capital theory the specification of joint endogeneity between female earnings and the divorce rate allows valid inferences to be made regarding the effect of female earnings on

the food retail revolution in poor countries is it coming or is it over abstract global retail chains are becoming increasingly dominant in the global food trade and their rise leads to dramatic impacts on agricultural supply chains and on small producers however the prospects and impacts of a food retail revolution in poor countries are not yet well understood here i examine this question in madagascar a poor but stable country in which global retailers have been present for over a decade the survey and analysis find that while global retail chains sell better quality food their prices are 40 90 higher ceteris paribus than those seen in traditional retail markets in poor settings characterized by high food price elasticities a lack of willingness to pay for quality and small retail margins supermarkets appear to set prices with an eye toward maximizing profits on the basis of price inelastic demands for quality products from a small middle class interested in one stop shopping it seems unlikely that global retail chains will further increase their food reta

global value chains and market formation process in emerging export activity evidence from ethiopian flower industry abstract this article provides a case study of the ethiopian flower export industry which successfully emerged at time when the eu market main destination was already characterised by increasingly stringent standards and delivery requirements entering this market required a multitude of capabilities at firm sector and national levels several of these capabilities were absent or weak in the domestic market when the new activity kicked off the article analyses how the capabilities of individual firms and the industry at large co evolved and the role of various actors in the market formation process

private sector development policies practices and problems private sector development psd has become a central concern of most donors development cooperation efforts during the last decade this paper is a critical review of policies in the area donors work with concepts of psd which are highly abstract treat developing countries private sectors as tabula rasa and focus mainly on macro level preconditions in practice however concrete psd policies are mostly micro level ones the paper argues that they are shaped mostly by the nature and interests of private sectors in donor country themselves incorporate a high proportion of tied aid and fail basic tests of coherence

marriage and trust some lessons from economics this paper examines the role of marriage as an institution for providing couples with the confidence to make long term investments in their relationship no fault divorce has undermined the notion of marriage as a contract thereby reducing the security offered by marriage and promoting opportunism by men this has weakened the bargaining power of wives both within marriage and when divorce occurs current legal reforms will improve the economic position of all divorced wives including those who are primarily responsible for the breakdown of their marriage the latter feature will encourage opportunism by women and make men less prepared to invest in their marriage the paper argues that the only way to achieve parity between men and women and deter opportunism by either sex is to return to fault based divorce both divorce settlements and the custody of children should depend on preceding marital conduct

firms adoption of international standards evidence from the ethiopian floriculture sector global trade in agriculture and food products is increasingly governed by an array of standards a survey conducted in 2010 covering all operational firms in the nascent floriculture industry in ethiopia revealed that only 36 per cent have managed to acquire certification for international private standards this study uses a census based panel dataset from ethiopian floriculture to empirically examine the determinants of firms adoption of international private standards it also analyses overall industry level efforts and public private partnership to launch and implement a national scheme for good agricultural practice and build firms capacity to comply with the standards key words standards certification floriculture exports estate farms ethiopia africa

female labor supply and divorce new evidence from ireland if participation in the labor market helps to secure women s outside options in the case of divorce separation an increase in the perceived risk of marital dissolution may accelerate the increase in female labor supply this simple prediction has been tested in the literature using time and or spatial variation in divorce legislation e g across us states leading to mixed results in this paper we suggest testing this hypothesis by exploiting a more radical policy change i e the legalization of divorce in ireland the right to divorce was introduced in 1996 followed by an acceleration of marriage breakdown rates we use this fundamental change in the irish society as a natural experiment we follow a difference in difference approach using families for whom the dissolution risk is small as a control group our results suggest that the legalization of divorce contributed to a significant increase in female labor supply mostly at the extensive margin results are not driven by selection and are robust to several specification checks including the introduction of household fixed effects and an improved match between control and treatment groups using propensity score reweighting

divorce rates and bankruptcy exemption levels in the united states abstractalthough increasing bankruptcy exemption levels protects consumers from negative asset shocks an unintended consequence of this policy that remains unexplored is the effect on divorce rates this effect arises from reducing the benefits of marital risk sharing i establish conditions under which increases in exemption levels lead to more divorce and investigate using data from vital statistics of the united states i estimate that increases in exemption levels occurring between 1989 and 2005 resulted in more than 200 000 additional divorces during this period and that the effect on divorce rates in 2005 is comparable in magnitude to that found for the introduction of unilateral divorce laws by wolfers

trade standards and poverty evidence from senegal summary in the debate on trade and poverty it is argued that standards act as trade barriers and cause marginalization of the poor this paper quantifies income and poverty effects of high standards trade and integrates labor market effects by using company and household survey data from the vegetable export chain in senegal we find that exports grew sharply despite increasing standards contributing importantly to rural incomes and poverty reduction tightening standards induced a shift from smallholder contract farming to integrated estate production altering the mechanism through which poor households benefit through labor markets instead of product markets

mainstreaming fair trade coffee from partnership to traceability summary this article analyzes the recent growth of fair trade and the mainstreaming of this previously alternative arena focusing on coffee i identify a continuum of buyers ranging from mission driven enterprises that uphold alternative ideas and practices based on social ecological and place based commitments to quality driven firms that selectively foster fair trade conventions to ensure reliable supplies of excellent coffee to market driven corporations that largely pursue commercial industrial conventions rooted in price competition and product regulation using a commodity network approach my analysis illuminates the impacts of diverse buyer relations on producer groups and how relations are in some cases shifting from partnership to traceability

the validity of profits structure studies with particular reference to the ftc s line of business data the simple proposition that consumerdamaging collusion is more likely to occur when there are fewer competitors has given rise not only to legal restrictions of economic activity thought to restrict output but also to an enormous amount of empirical work attempting to relate market concentration to the exercise of monopoly power most such studies measured market structure by an index of concentration for example four firm concentration or herfindahl and performance by accounting profit for example net profit divided by assets or price cost margins sales less direct costs divided by sales from the positive statistically significant correlations often found between greater concentration and profit with other factors presumably accounted for some researchers conclude that increases in concentration are anticompetitive and that concentration therefore is bad the concentration profits studies have been criticized essentially on two grounds one is that the positive relationship is not indicative of collusive behavior in particular oliver williamson 1968 john mcgee 1971 harold demsetz 1973 1974 and sam peltzman 1977 point out that higher profits could result from efficiencies experienced by large firms which resulted both in greater market shares and high levels of concentration analytical arguments show that higher profits logically follow as much from lower costs that are associated with higher levels of concentration as from collusion determined higher prices some empirical evidence that supports this belief is presented by demsetz peltzman and bradley gale and ben branch 1982 however their findings have been contested on the grounds that the data used are biased or inadequate or that the researchers have not demonstrated that the observed higher profits greater concentration relationship was caused by lower costs 2 the second criticism is that available data provide an inadequate basis for such conclusions the concentration numbers are based usually on industries defined by the commerce department s standard industrial classifications sic the sic definitions tend to be supply production rather than demand determined include nonhomogeneous products and exclude sales of similar products that are included in different sic groups or are imported the profit data are taken from accounting reports that provide poor measures of economic values weiss 1974 describes many of these problems however he does not believe that these shortcomings invalidate the studies as weiss 1979 concludes

comparison of private incentive mechanisms for improving sustainability of filipino tuna fisheries this paper analyzes the influence of three private incentive mechanisms over decision making related to improved sustainability of fishing practices in filipino tuna fisheries the three mechanisms compared are the world wildlife fund for nature s fishery improvement project model marine stewardship council certification and the international seafood sustainability foundation pro active vessel register the main question addressed in this paper is how and to what extent the private incentive mechanisms support the development of fisher capabilities to respond to the requirements set out by these mechanisms applying a global value chain approach to analyze results collected from key actors involved in philippine tuna fishers contributing to both domestic and regional economic development in the western pacific we explore the structure and function of these private incentive mechanisms in achieving both environmental and economic development outcomes our results show that these private incentive mechanisms deliver different direct and indirect incentives for changing to more sustainable fishing practices and that the success of these mechanisms is dependent on the extent to which the mechanisms support the development of target fisher capabilities to comply with their sustainability requirements we conclude that the future success of these incentive mechanisms depends for a large part on stricter sustainability requirements but also on the capacity of the mechanisms to incentivize the inclusion of more developing country fishers these findings contribute to a wider understanding of how the capabilities of developing country producers are influenced by their relationship with chain and non chain actors and with the wide institutional arrangements that the producers operate in

coping with the upheavals of globalization in the shea value chain the maintenance and relevance of upstream shea nut supply chain organization in western burkina faso summary market globalization has had only a weak impact on the regional shea nut supply chain in western burkina faso despite the boom in the shea trade and the arrival of leading foreign firms we show that despite the fact that wholesalers have kept the shea chain locked in an oligarchic organization for the last 50 years they still play an important role in the smooth functioning of the chain and in profit sharing down the chain to the rural poor we suggest that development actors should consider shea traders and their role in the coordination of the chain more carefully 2014 the authors published by elsevier ltd this is an open access article under the cc by nc sa license http creativecommons org licenses by nc sa 3 0

marriage divorce and interstate risk sharing in this paper we study the importance of marriage for interstate risk sharing in the us we find that us federal states in which married couples account for a higher share of the population are less exposed to state specific output shocks thus in addition to improving the allocation of risk at the individual level marriage also has implications for risk sharing at the more aggregated state level quantitatively the impact of marriage on interstate risk sharing varies over divorce regimes

partial vertical integration risk shifting and product rejection in the high value export supply chain the ghana pineapple sector summary high value export supply chains hold potential to improve smallholders welfare but their relative production inefficiency and moral hazard problems can cause exporters to prefer vertically integrated plantation production however pineapple exporters in ghana produce both for their own account and purchase from smallholders we hypothesize that vertical integration is only partial because exporters face large market risks that smallholders surprisingly are better able to absorb we show empirically that exporters average rejection rate of export quality fruit is high and varies in response to unanticipated fluctuations in european demand these results support the hypothesis and are consistent with theories of partial vertical integration but not the standard principal agent paradigm

agrifood supply chain private sector standards and farmers health evidence from kenya this article evaluates the impact of adoption of european union eu private sector standards on farmers health in rural kenya the study utilizes cross sectional farm household level data collected in 2006 from a randomly selected sample of 439 small scale export farmers we estimate the casual impact by utilizing a two stage poisson regression model two stage standard treatment effect model as well as by regression based on propensity score to assess the robustness of the results using these techniques we demonstrate that the pesticide ascribed incidence of acute illness symptoms and the associated cost of illness significantly decrease with the adoption of standards ceteris paribus farmers who adopt standards experience 70 lesser incidence of acute illness and spent about 50 60 less on restoring their health than nonadopters although standards can potentially prevent resource poor smallholders from maintaining their position in lucrative export markets they can also result in positive changes in the health of those farmers who do adopt them as shown by these results this implies that if adopted on a large scale standards may reduce production externalities corroborating the view that they may serve as a catalyst to transform production systems in developing countries

no fault divorce laws and the labor supply of women with and without children we use a difference in difference in difference estimator to compare changes in labor force participation weeks and hours of work associated with no fault divorce laws allowing for differential responses for married women with and without children although other research has found that the labor supply of women in general does not respond to no fault divorce laws we find that no fault divorce laws are associated with increases in the labor supply of married mothers relative to married nonmothers even after controlling for changes in female labor supply in states without no fault divorce laws and for property division rules associated with the laws

marriage divorce and legal change new evidence from england and wales in this article we explain the evolution of divorce rates in england and wales over the post war period following the approach of the predominantly north american literature in this area we focus on the liberalization of divorce law and socioeconomic factors as determinants of the divorce rate in line with the development of the literature we find that the introduction of liberalized no fault divorce law had a significant effect on the divorce rate in england and wales the finding that the law affects the divorce rate is consistent with the view that marriage is characterized by indivisibilities that inhibit coasian bargaining

responsible retailing the practice of csr in banana plantations in costa rica during the last 10 years or so a number of corporate social responsibility csr initiatives have been introduced in global supply chains which aim to improve the conditions of workers engaged in producing goods for export this article discusses the observations of csr in practice in the costa rican united kingdom uk banana chain the banana chain makes for an interesting case study because there are dominant corporate actors at each end who are in a position to influence the conditions experienced by workers on banana plantations at the top of the chain there are four major uk supermarket groups who control access to the retail market and as self appointed guardians of consumer interest are demanding that producers adopt more socially responsible practices at the other end banana production is highly integrated and controlled by three large north american agri businesses who have developed their own social and environmental certification programmes costa rica also makes for an interesting country to locate the study as it has a tradition of state led policies to protect worker rights yet in spite of csr commitments made by both supermarkets and producers that emphasise health and safety and the country s established labour law this article shows that there are problems for workers when they are forced to meet demanding production schedules furthermore it suggests that whilst supermarkets continue to drive down consumer prices and put pressure on producers to reduce costs a downward spiral of working conditions is created regardless of the csr policies in place however this article also identifies that changes to supermarket behaviour is possible when consumer trust is at stake

developing agricultural markets in sub saharan africa organic cocoa in rural uganda abstract this article investigates the process of development in a traditional african export market focusing on a contract farming scheme for organic cocoa in rural uganda based on a repeated household survey we measure the impact of the scheme on the income of participants and the economic mechanisms behind these effects we find substantial benefits from the scheme driven primarily by the establishment of credible incentives for farmers to adopt technologies which improve cocoa quality there is also evidence of broader trends of market deepening and increased productivity probably due to positive spillovers

structural transformation and smallholder agriculture an information theoretic analysis of the nicaraguan case in light of continued debate regarding the capacity of small scale agricultural producers to compete amidst globalization and or liberalization we examine recent trends in the distribution and use of agricultural landholdings in developing nations via refined exploration of the nicaraguan case with nationally representative living standards measurement survey type data for the years 1998 2001 and 2005 we employ markov chain methods within an information theoretic framework in an attempt to advance the analysis of structural transformation in developing countries beyond the examination of trends in mean farm sizes or gini coefficients approaches ill suited to the detection of the apparent complexities of structural change further while markov chain analysis has witnessed relatively widespread application in the investigation of structural transformation in developed nations we offer a novel methodological extension by allowing for the simultaneous exploration of structural transformation across multiple dimensions namely structural change in both the distribution and use of agricultural landholdings as well as the incorporation of microlevel determinants of farm size and land use change the results of the inquiry above all suggest that nicaragua s agricultural and livestock sector is characterized by a definitive persistence of smallholders while a moderate tendency toward bifurcation in the distribution of landholdings would appear to obscure any immediate relationship between operational landholdings and land productivity we contend that such trends are in fact consistent with the often observed inverse farm size productivity relationship

a financial contracting approach to the role of supermarkets in farmers credit access traditional moneylenders monitor farmers to ensure that their investment is not diverted modern farming contracts offered by supermarkets in developing countries often entail a loan component and monitoring arises as well however unlike moneylenders supermarkets do care about the attributes of the product whether such attributes are obtained is influenced largely by the advice and the extension services received by farmers we build a financial contracting model where we show that supermarkets optimally undertake both the monitoring and the advisory missions this contract is shown to potentially enhance credit access for small farmers but sometimes also involves excessive monitoring

agricultural growth and economic development a view through the globalization lens this article re visits the age old proposition that agriculture growth contributes to overall economic development and asks whether the relationship still holds in an increasingly globalized world there is overwhelming empirical support for the above proposition indeed it is hard to find exceptions barring a few city states where sustained economic development has not been preceded by robust agricultural growth however there are a large number of countries that have witnessed neither agricultural growth nor economic development even in countries where agricultural growth has been significant dramatic inter regional differences persist this article examines the factors that contribute to or constrain the process of agricultural transformation does the process of globalization and the resultant changes in agrifood systems offer new opportunities for agriculture led growth or will it further marginalize excluded countries regions and groups the factors that cause exclusion are examined both in terms of globalization forces and in terms of domestic shortcomings in policies and governance policy interventions that attempt to reduce the costs of transition to a globalized agricultural system are explored including safety nets for those left behind

governance and trade in fresh vegetables the impact of uk supermarkets on the african horticulture industry production of fresh vegetables for export has grown rapidly in a number of countries in sub saharan africa over the last decade this trade brings producers and exporters based in africa together with importers and retailers in europe large retailers in europe play a decisive role in structuring the production and processing of fresh vegetables exported from africa the requirements they specify for cost quality delivery product variety innovation food safety and quality systems help top determine what types of producers and processors are able to gain access to the fresh vegetables chain and the activities they must carry out the control over the fresh vegetables trade exercised by uk supermarkets has clear consequences for inclusion and exclusion of producers and exporters of differing types and for the long term prospects for the fresh vegetables industry in the two major exporting countries studied kenya and zimbabwe

global value chains labor organization and private social standards lessons from east african cut flower industries summary this article examines the opportunities and challenges that private social standards pose for labor organizations it explores different labor responses to private social standards in east african cut flower industries the analysis incorporates the concept of labor agency in global value chain analysis and reveals how retailer driven chains offer more room for labor organizations to exercise their agency than the traditional cut flower value chains labor organizations have been able to influence social standard setting and implementation and to use standards to further labor representation at production sites however labor organizations ability to seriously challenge the prevailing governance structure of the cut flower value chain appears extremely limited

marriage and divorce informational constraints and private contracting the relationship between divorce rates in the united states and laws regulating divorce are analyzed using data from a special current population survey undertaken in 1979 with particular reference to the adoption by many states of no fault divorce laws the author utilizes a contract theoretic framework to examine the impact of both legal and informational constraints on several aspects of the marriage relationship 1 the probability of divorce 2 compensation at divorce i e the terms of the divorce settlement 3 the probability of entering marriage and 4 incentives for investment in marriage specific capital two different models are developed the first assumes that ex post information about the value of each spouses opportunites at divorce is symmetric and that since divorce would only occur if the joint benefits outweigh the joint costs the law has no effect on the divorce rate the second model asserts that the existence of asymmetric information results in a fixed wage marriage contract and that divorce would be higher in states that allow unilateral divorce the evidence supports the first of these hypotheses excerpt

a gendered value chain approach to codes of conduct in african horticulture codes of conduct covering the employment conditions of southern producers exporting to european markets mushroomed throughout the 1990s especially in the horticulture sector linking uk and european supermarkets with export firms in africa the majority of employment in this sector is informal a significant proportion of which is female this paper explores the gender sensitivity of codes currently applied in the african export horticulture sector from an analytical perspective that combines global value chain and gendered economy approaches through an analysis of these two approaches it develops a gender pyramid which provides a framework for mapping and assessing the gender content of codes of conduct the pyramid is applied to codes that cover employment conditions in three commodity groups and countries exporting to european markets south african fruit kenyan flowers and zambian vegetables and flowers it concludes that the gender sensitivity of codes needs to be greatly enhanced if they are to adequately address employment conditions relevant to informal and especially women workers

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

quantifying value chain analysis in the context of livestock systems in developing countries the analysis of value chains has augmented our knowledge on the complexities inter linkages distributional benefits and institutional arrangements of production and marketing channels in developing countries however the analysis remains relatively qualitative and case specific with limited ability to rank or assess the impact of alternative interventions or to analyze sufficiently the complex market dynamics and feedbacks present in livestock systems this paper offers theoretical and applied insights on ways to improve the analytical rigor of the value chain methodology that combines both qualitative and quantitative approaches
