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

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

an analysis of the selection of arbitrators this paper analyzes alternative mechanisms for the selection of arbitrators the authors review key institutional features of the threemost prevalent mechanisms for selecting arbitrators rank veto alternate strike and rotating panel they present a more formal analysis in which these mechanisms are treated as economic games andanalyze the alternative mechanisms in terms of the incentives they provide for strategic behavior and the efficiency of any equilibrium strategies that exist some implications of varying selected parametersof each mechanism are derived and the general role of arbitrator selection mechanisms in the process of bargaining under the threat ofarbitration are considered copyright 1986 by american economic association

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

rural infrastructure transactions costs and market participation in kenya abstract we develop a conceptual framework for quantifying fixed transactions costs facing semisubsistence households using household survey data from a sample of 324 kenyan maize farmers we jointly estimate household supply and demand schedules and transactions costs econometric results indicate that on average the ad valorem tax equivalent of fixed transactions costs for households in our sample is 15 additional analysis indicates that economic isolation is positively associated with the size of transactions costs to the best of our knowledge ours are the first empirical estimates of the magnitude of fixed transactions costs for agricultural households in developing countries

an analysis of childhood malnutrition in rural india role of gender income and other household characteristics there are controversies regarding the role of individual and household characteristics in childhood nutritional status measured by anthropometric indicators using a nutrition index based on weight for age of children in rural india the paper re examines this issue ordered probit estimates of nutritional status suggest female literacy improves the nutritional status of boys at the cost of girls while higher per capita current income improves that of both boys and girls though the impact is higher for boys however effect of income is not robust when we use instruments of longer run income but more income and literacy give more ways to discriminate between boys and girls

comparative productivity the ussr eastern europe and the west this paper compiles comparative measures of output per worker in 1975 in four socialist and seven western market economy wme countries and explores sources of observed differences between the two groups of countries in that regard such differences seem explicable only partially by reference to differences in per worker capital stock and farm land a residual disparity of 25 to 34 percent in favor of wme countries appears to testify to superior efficiency in the latter copyright 1987 by american economic association

spillovers from modern supply chains to traditional markets product innovation and adoption by smallholders there is an emerging body of literature analyzing how smallholder farmers in developing countries can benefit from modern supply chains however most of the available studies concentrate on export markets and fail to capture spillover effects that modern supply chains may have on local markets here we analyze the case of sweet pepper in thailand which was initially introduced as a product innovation in modern supply chains but which is now widely traded also in more traditional markets using survey data from smallholder farmers and econometric techniques we show that sweet pepper cultivation contributes significantly to higher household incomes strikingly at this stage participation in modern supply chains does not lead to higher incomes than supplying sweet pepper to traditional markets however the results also indicate that missing land titles weak infrastructure conditions and limited access to information constituted serious constraints during the early phases of sweet pepper adoption such constraints need to be overcome so that smallholder farmers are better prepared for the prompt reactions needed under rapidly changing market conditions

reliant behavior in the united states and japan yoshiharu mataga japanese economic success is often attributed to culturally reinforced psychological conditioning that promotes interpersonal reliance cooperation and a group interest orientation this article provides direct experimental evidence on differences in behavior among future businesspeople in the united states and japan utilizing a simple two person extensive form game of perfect information introduced by selten 1975 we provide evidence that contrary to some views the japanese can be less reliant on the behavior of others and are more likely to take actions at variance with group welfare in some settings thus popular explanations of japanese economic achievements may require further exploration jel a14 f00 m14 p52 i introduction the role of culture in economic behavior is an important but controversial topic although it is widely believed that cultural influences affect economically relevant behavior such effects can present difficulties for conventional economic theory discussions of the differences between the united states and japan in the business sphere provide a good example of both the high degree of academic and popular interest in this topic and the complexities involved in obtaining useful characterizations a common popular conclusion in the japan versus united states debate is that japanese business practices differ fundamentally from united states practices and that these differences stem from dissimilar sociological conditioning in the two countries while united states or western culture stresses individualism personal initiative and risk taking the japanese are said to place a higher value on consensus cooperation favoritism toward within group peers and stability 1 therefore a citizen in japan may be more interested in how he or she fits into the social context and his or her relationship with others 2 these contrasting orientations are assumed to manifest themselves in different patterns of behavior having economic implications this article offers a direct controlled experimental test of potentially significant differences in behavior between future japanese and american businesspeople utilizing a simple two person game of perfect information we examine the degree to which united states and japanese business students make differing assessments of the reliability of the behavior of their compatriots and we provide evidence on the implications of these assessments for observed behavior our simple game template introduced by selten 1975 was the focus of a study by beard and beil 1994 and allows comparison of a kind of behavior reliance on maximizing play by others that may have important economic implications in our usage reliance means merely that one player assigns a sufficiently high probability to self interested behavior by other players to induce the first player to take actions that are desirable only when others maximize their own monetary payoffs thus reliance differs from trust as usually defined in gam e theory and the former appears considerably weaker our experiments use as subjects business students in roughly comparable american and japanese universities and we offer nontrivial immediate money payoffs to participants in order to solicit serious efforts on their parts several versions of the basic experiment are conducted to establish payoff dominance and evaluate hypotheses on subject behavior our findings are quite surprising first subjects in both the united states and japan are loath to rely on others maximizing behavior even when that behavior is as in the united states highly reliable second contrary to the assumptions underlying some analysis of japanese business practices subjects in japan appear less reliant than their united states counterparts the article is divided into five sections section ii provides a literature review on the role of culture in u

expectation formation mechanisms profitability of foreign exchange trading and exchange rate volatility an attempt is made to identify the expectation formation mechanism dominating the foreign exchange market and to demonstrate that exchange rate volatility can be attributed to the heterogeneity of traders with respect to expectation formation the criterion used to identify the dominance of a particular mechanism is the profitability of trading based on that mechanism it is concluded that mixed and extrapolative expectations are the dominant mechanisms that market participants follow some sort of a herd behaviour and that they pay attention to the expectations of other participants it is also found that the heterogeneity of market participants with respect to expectation formation goes a long way towards explaining volatility

using survey data to test standard propositions regarding exchange rate expectations survey data provide a measure of exchange rate expectations superior to the forward rate in that no risk premium interferes we estimate extrapolative adaptive and regressive models of expectations static or random walk expectations and bandwagon expectations are rejected current appreciation generates the expectation of future depreciation because variables other than the contemporaneous spot rate receive weight in comparing expectations to the process governing the spot rate we find statistically significant bias no variable is as ubiquitous in international financial theory and yet as elusive empirically as investors expectations regarding exchange rates in the past expectations have been modeled in an ad hoc way often by using the forward exchange rate there is however a serious problem with using the forward discount as the measure of the expected change in the exchange rate in that the two may not be equal the gap that may separate the forward discount and expected depreciation is generally interpreted as a risk premium most of the large empirical literature testing the unbiasedness of the forward exchange rate for example has found it necessary either arbitrarily to assume away the existence of the risk premium if the aim

managing food price risks and instability in a liberalizing market environment overview and policy options abstract managing food price risks and instability is a major challenge in the midst of ongoing food market reforms key findings from the papers in this special volume revolve around five broad areas i the sources and magnitudes of food price instability in different country contexts ii the economic and social costs stemming from price instability iii the lessons from food market reforms to date iv the design of policy reforms in ways that promote efficient and stable market development and protect the interests of the poor and v potential policy responses to food price instability in a liberalizing market environment

impact of contract farming on income linking small farmers packers and supermarkets in china summary this study compares contract and non contract growers of apples and green onions in shandong province china in order to explore the constraints on participation and the impact of contract farming on income we find little evidence that firms prefer to work with larger farms though all farms in the area are quite small using a heckman selection correction model we find that contract farming raises income even after controlling for observable and unobservable household characteristics these results suggest that contract farming can help raise small farm income though questions remain regarding the number of farmers that can be brought into such schemes 2009 elsevier ltd all rights reserved

arbitration and bargaining across the pacific this paper reports laboratory experiments comparing arbitration behavior between and across two countries with extensive trade relations the united states and japan besides comparing disputes in both locations we evaluate disputes between them while we find nominal differences between the countries we observe significant changes in both groups behavior when facing someone from the other country specifically americans seek larger profits when facing a japanese counterpart and japanese subjects settle more frequently with an american counterpart our results suggest that the literature on bargaining behavior across cultures paints an incomplete picture of international comparisons by failing to consider bargaining interactions

the causes of bargaining failure evidence from major league baseball abstract final offer arbitration in major league baseball provides an ideal setting for examining the empirical regularities that are associated with bargaining failure since final offers salaries and player statistics which provide the fundamental facts for the case are all readily available using data for players eligible for arbitration for 1990 93 we conduct a wide variety of empirical tests regarding the relationship between aggressive offers and arbitration outcomes we find that aggressive offers by players trigger arbitration and that more aggressive offers are associated with inferior financial outcomes in arbitration overall clubs appear to outperform players in arbitration unexpectedly high or low offers are less common for players who have previously been through arbitration which suggests that learning occurs our results are inconsistent with simple one sided asymmetric information models of arbitration the results are more consistent with an optimism model or a model in which so

equilibrium strategies for final offer arbitration there is no median convergence final offer arbitration is a procedure for settling disputes between two parties in which an arbitrator chooses the final offer of the party closest to what he considers a fair settlement this procedure is modeled as a two person zero sum game of imperfect information in which the parties are assumed to know the probability distribution of the arbitrator s fair settlements and to make bids in an infinite strategy space that maximize their expected payoffs necessary and sufficient conditions for there to be local and global equilibria in pure strategies are derived and necessary conditions for mixed strategies in a particular case are found such equilibria when they exist in pure strategies represent bids which are symmetric about the median and for most common distributions are separated from one another by two or more standard deviations this finding suggests that final offer arbitration may not accomplish its avowed purpose of inducing the two parties to converge on what they perceive to be t

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

empirical models of the exchange rate separating the wheat from the chaff various popular exchange rate models a standard monetary model a portfolio balance model and sticky price models are estimated and evaluated using u s canadian data for the 1970s nonnested hypothesis tests demonstrate that none are correctly specified the data suggest 1 the exchange rate persistence observed is not fully explained by any of the models 2 the small durbin watson statistics indicate longer lags are required 3 the current account is a useful explanatory variable 4 the portfolio balance model fits the data well but has potentially serious problems measuring the stock of foreign assets this abstract was borrowed from another version of this item

rewards experience and decision costs in first price auctions consistent with a model of asymmetric risk aversion subjects in first price auctions consistently bid above the risk neutral nash prediction it has been argued that this is due to low opportunity cost of deviating from the risk neutral bid we increase opportunity cost and payoff levels by factors of 0 1 5 10 and 20 from the normal levels generating payoffs up to 250 for risk neutral subjects and observe an insignificant increase in the slope of individual bid functions the rmse of bids declines significantly this is consistent with a reward decision cost model of bidding behavior

exchange rate models and exchange rate expectations an empirical investigation a non parametrictest of popular modern exchange rate models under alternative expectation specifications is presented it is found that there is little difference in the predictive success of the alternative exchange rate models however there are significant differences in the performance of a model depending upon the expectations mechanism specified our most important finding is that the flexible price monetary model the portfolio balance model and a hybrid model under extrapolative and adaptive expectations mechanisms provide statistically significant information about the direction of exchange rate movements by contrast the same models when employing static regressive and rational expectation mechanisms do not provideany satistically significant information

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

a comparison of conventional final offer and combined arbitration for dispute resolution two widely used forms of arbitration are conventional arbitration in which the arbitrator makes an unconstrained settlement choice and final offer arbitration in which the arbitrator must choose between disputants final offers under an innovative as yet unused approach called combined arbitration if the arbitrator s notion of a fair settlement lies between the disputants final offers final offer arbitration rules are used otherwise conventional arbitration rules are used theoretically by combining the risks that the two standard forms of arbitration pose for disputants who do not voluntarily settle combined arbitration should generate convergent final offers the results of this controlled laboratory study show however that dispute rates are highest in combined arbitration and lowest in conventional arbitration these results challenge the theoretical predictions for combined arbitration as well as claims that final offer arbitration should reduce disputes compared to conventional arbitration the results are however consistent with a simple theory of disputant optimism

flexible exchange rates prices and the role of news lessons from the 1970s recent experience with flexible exchange rate systems has led to renewed interest in the operation of foreign exchange markets as reflected in many recent studies of the principal determinants of exchange rates the 1970s witnessed the dramatic alteration of the international monetary system from a regime of pegged exchange rates which prevailed for about a quarter of a century since the bretton woods conference into a regime of flexible though managed rates as a consequence of the emergence of the new legal and economic system traders national governments and international organisations were confronted with new economic problems choices and instruments during the 1970s ex change rates fluctuated widely and inflation rates accelerated the international monetary system had to accommodate extraordinarily large oil related shocks which affected trade flows in goods and assets huge oil payments had to be recycled uncertainties concerning future developments in international politics reached new heights and the prospects for the world economy got gloomier these developments placed unprecedented pressures on the markets for foreign exchange as well as on other asset markets they were associated with a large slide in the value of the us dollar and resulted in speeding up the creation of new institutions like the european monetary system which provided the formal framework for the management of exchange rates among members

westernization of asian diets and the transformation of food systems implications for research and policy abstract rapid economic and income growth urbanization and globalization are leading to a dramatic shift of asian diets away from staples and increasingly towards livestock and dairy products vegetables and fruit and fats and oils while the diversification of diets away from the traditional dominance of rice with rising incomes is expected and observed current food consumption patterns are showing signs of convergence towards a western diet the diet transition is characterized by increased consumption of wheat temperate fruit and vegetables and high protein and energy dense food globalization and the consequent global interconnectedness of the urban middle class is the driving force behind the convergence of diets the rapid spread of global supermarket chains and fast food restaurants is reinforcing the above trends the growing demand for diet diversity cannot be met solely by the traditional food supply chain it requires the modernisation of the food retail sector and the vertical integration of the food supply chain in effect linking the consumers plate to the farmers plow as a consequence asian agriculture is on an irreversible path leading away from its traditional pre occupation with cereal crop production especially rice towards a production system that is becoming increasingly commercialized and diversified this paper describes the determinants and trends in the diversification and westernization of asian diets implications of the evolving demand trends for food supply and retail systems are presented the paper discusses the prospects for small farmer participation in the emerging food supply system with a particular emphasis on asian rice production systems finally the paper considers emerging challenges for food policy small holder welfare and agricultural research and development priorities

post green revolution food systems and the triple burden of malnutrition developing country food systems have changed dramatically since the green revolution period at the same time malnutrition still represents a challenge and is now understood to encompass the three simultaneous dimensions of undernourishment micronutrient deficiencies and over nutrition manifest in overweight and obesity these changes in food systems and in the understanding of the global malnutrition challenge necessitate fresh thinking about food systems based strategies to reduce malnutrition this paper introduces a special section that offers such new perspectives we discuss trends with respect to indicators of the triple burden of malnutrition to understand the extent of global malnutrition challenges and then relate those to food systems transformation in developing countries

some urban facts of life implications for research and policy abstract this review of recent literature explores the challenges to urban food and nutrition security in the rapidly urbanizing developing world the premise of the manuscript is that the causes of malnutrition and food insecurity in urban and rural areas are different due primarily to a number of phenomena that are unique to or exacerbated by urban living these areas include a a greater dependence on cash income b weaker informal safety nets c greater labor force participation of women and its consequences for child care d lifestyle changes particularly diet and exercise patterns e greater availability of public services but questionable access by the poor f greater exposure to environmental contamination and g governance by a new possibly nonexistent set of property rights the main focus is on identifying what is different about urban areas so as to better frame the program and policy responses

farmers welfare and changing food prices nonparametric evidence from rice in madagascar this paper uses nonparametric density estimation and kernel smoothing techniques to examine the instantaneous distributional implications of rice price changes in madagascar while many farmers do not participate in product markets as either buyers or sellers and net sales or marketable surplus are fairly small for many others the roughly one third of rice farmers who fall below the poverty line face significant negative first order welfare effects from increases in the mean or variance of rice prices conversely the first order gains from rice price increases are highly concentrated among the largest rice farmers and particular regions in madagascar

floating exchange rates expectations and new information abstract this paper analyzes the relationship between forward exchange rates future spot rates and new information a stochastic model of exchange rate determination is used to formally show how unanticipated changes in the exchange rate determinants or news affect the spot rate the empirical analysis indicates that new information plays an important role in explaining the market forecasting error or difference between the spot rate and the forward rate determined in the previous period

exchange rate pass through into german import prices a disaggregated perspective this study analyses the exchange rate pass through into german import prices based on disaggregated data taken on a monthly basis between 1995 and 2012 our main contribution is twofold firstly we employ various time series techniques to analyse data for different product categories and also cointegration techniques to carefully distinguish between short run and long run pass through coefficients secondly in a panel data approach we estimate time varying pass through coefficients and explain their development with regard to various macroeconomic factors our results show that long run pass through is only partly observable and incomplete whereas short run pass through shows a more unique character although heterogeneity across product groups does exist we are also able to identify several macroeconomic factors that determine changes in the degree of pass through which is especially relevant for policymakers

an experimental comparison of dispute rates in alternative arbitration systems this paper reports the results of a systematic experimental comparison of the effect of alternative arbitration systems on dispute rates the key to our experimental design is the use of a common underlying distribution of arbitrator fair awards in the different arbitration systems this allows us to compare dispute rates across different arbitration procedures where we hold fixed the amount of objective underlying uncertainty about the arbitration awards there are three main findings first dispute rates are inversely related to the monetary costs of disputes dispute rates were much lower in cases where arbitration was not available so that the entire pie was lost in the event of a dispute this confirms the empirical importance of the so called chilling effect on bargaining that has been conjectured is produced by the adoption of arbitration systems second the dispute rate in a final offer arbitration system is at least as high as the dispute rate in a comparable conventional arbitration system contrary to the usual argument we find no evidence that final offer arbitration eliminates the chilling effect third dispute rates are inversely related to the uncertainty costs of disputes dispute rates were lower in conventional arbitration treatments where the variance of the arbitration award was higher and imposed greater costs on risk averse negotiators our results can also be interpreted as providing tentative evidence that the negotiators were risk averse on average finally we find general agreement between the dispute rates in our experiment and dispute rates found in the field in comparable settings

regime shifts and the canada us exchange rate in a multivariate framework this study re evaluates the monetary approach for the canada u s exchange rate and shows that its basic structure can be verified although the coefficients are not consistently in line with theory our findings also indicate that exchange rate adjustment is subject to regime shifts

learning in equilibrium models of arbitration this paper analyzes strategic communication in equilibrium models of conventional and final offer interest arbitration both models emphasize the role of learning by the arbitrator from the parties offers about the state of the employment relationship which is known to the parties but not to the arbitrator in both models the arbitrators equilibrium behavior is identical to the reduced form decision rule typically assumed in the empirical literature the paper thereby provides a structural interpretation for the existing empirical work the paper also represents progress towards a complete theory of arbitration because it satisfies three conditions that will be required of any such theory first the models predictions match the existing empirical evidence second the models describe equilibrium behavior and third the models are built on a common set of assumptions about preferences information and commitment the paper therefore not only provides an equilibrium foundation for the intuition that the arbitrator might learn from the parties offers but also uses the idea of learning to develop a unified analytical treatment of the two major forms of interest arbitration this abstract was borrowed from another version of this item
