specific experience household structure and intergenerational transfers farm family land and labor arrangements in developing countries data from indian rural household survey was used to test th hypothesis that the coexistence in traditional rural societies of extended intergenerational families infrequent land sales and high reliance on family members as farm laborers is the result of the economic advantages which accrue from the knowledge gained by farming a particular ploy of land over a long period of time the land specific experience of elderly members of a intergenerational household who farmed the land as a child and then as an adult are expecially critical in adverse weather years most previous investigators attributed the existence of multigenerational households the use of family members rather than hired laboreds and the infrequency of land sales to deficiencies in the market i e labor market imperfections and an absence of capital insurance and asset markets in the present investigations these same characteristics are viewed as having an economic advantages a model for estimating the contribution of the experience of the elderly household members to agricultural profits was developed and applied to data from a 3 year panel study of 2900 indian rural farm households the data was collected between 1968 71 by the national council of applied economic research the survey collected information on farm profits farm inputs demographic characteristics and the effects of weather conditions on profits a major limitation of the study was a lack of information on the duration of land ownership age of household members was substituted as a proxy for duration of ownership findings were consistent withe the hypothesis in poor agricultural years gross returns for households which contained an elderly household member were greater than the gross returns for comparable households which did not contain an elderly member the economic advantages of specific knowledge embodied in the experienced elderly farmer were comparable to the economic advantages which accrued to households whose members were more educated the hypothesis cannot fully explain the existence of intergenerational families since there is a relatively large proportion of such families among nonfarm families in many countries including india findings suggest that intergenerational families may provide for more occupational diversity and thereby reduce income risks the specific experience hypothesis has policy implications if technological changes are introduced the value of specific experience may be lost and the frequency of intergenerational households may decline the hypothesis may also explain why farmers are reluctant to agree to land redistribution and consolidation schemes this reluctance may disappear after sufficient technological change has occurred

status in markets this project tests for the effect of social status in a laboratory experimental market we consider a special box design market in which a vertical overlap in supply and demand ensure that there are multiple equilibrium prices we manipulate the relative social status of our subjects by awarding high status to a subset of the group based on one of two procedures in the first a subject s score on a trivia quiz determines his or her status in another subjects are assigned randomly to a higher status or lower status group in both treatments we find that average prices are higher in markets where higher status sellers face lowerstatus buyers and lower when buyers have higher status than sellers across all sessions the higher status side of the market captures a greater share of the surplus earning significantly more than their lower status counterparts

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

discount rates and credit markets theory and evidence from rural india three models of credit markets 1 the permanent income model 2 upward sloping credit supply to individual borrowers and 3 constrained credit due to imperfect enforcement are tested using credit market data and an experimental study of individuals discount rates in south india the permanent income model is rejected by both the discount rate and the credit market data the discount rate data are consistent with either of the other two models while the credit market data are consistent with a combination of these two models other explanations are found to be insufficient to explain the results of this study

the distribution of wealth measurement and models abstract analysts debating the consequences of a policy change for the wealth distribution may come to different conclusions because of different views about how the distribution should be defined and measured or about the processes determining the distribution the aim of this survey is to provide an analytical framework within which such conflicts may be assessed the first part of the paper discusses conceptual issues in the definition of wealth and compares methods of deriving estimates of wealth distribution the second and larger part of the paper surveys lifecycle and intergenerational models of the distribution of wealth including a discussion of the role played by inheritance the presentation is largely theoretical indeed one of the paper s conclusions is that empirical modelling of the wealth distribution is under developed at least for the purposes of addressing many topical policy issues

crop prices and the demand for titled land evidence from uganda abstract i investigate how agricultural prices affect demand for titled land using panel data on ugandan farmers and a price index that weighs international crop prices by the structure of land use at the sub county level higher prices increase farmers share of titled land i also present evidence of a positive impact of prices on agricultural incomes the effect of prices on land tenure is stronger when farmers have access to roads and markets when they have undertaken investment on the land and when households fear land grabbing

does redistribution reduce inequality the steady state effect on inequality of linear redistributive schemes based on the taxation of earnings inheritances or some combination of the two is examined dynasties that exhibit asexual reproduction and altruism are modeled earnings ability which may be correlated across generations is exogenous and drawn from a stationary distribution taxing inheritances increases inequality by reducing the intergenerational averaging of luck in an example paying out the tax revenue in uniform transfers typically does not reverse this result taxing lifetime wealth or income adds a lump sum tax on earnings making redistribution more successful however this success is sensitive to the relative size of mean earnings and inheritances

markets power and productivity in rural asia abstract this article deals with three themes first the evidence that rural markets are responsive to scarcity is open to two interpretations i that markets closely approach the competitive ideal and ii that such responses are also consistent with various market imperfections second there is the nature of power and its influence on economic transactions lacking a satisfactory definition of the concept many contributions dealing with power yield few insights third there is the relationship between agrarian structure and economic progress a signal accomplishment of some contributions has been to show that south asia s diverse experience casts considerable doubt on the proposition that this relationship is a simple one

agricultural land relations in the developing world in this paper we draw on a number of methodological approaches which have been used to explain land relations tenancy sharecropping and interlinking distress sales dualistic land ownership distributions classes and land reform and their variations over space and time we indicate that the explanatory power of theories on land relations hinges on the complexity market imperfections and distortions admitted in the analysis

economic relationship between access to land and rural poverty in nepal in the present socio economic structure of nepal land is the main source of income and consumption for the majority of nepalese this study analyses the economic relationship between access to land and poverty in nepal by establishing the link between land and consumption as well as land and income a generalised additive model gam and ordinary least squares ols demonstrate that greater access to land increases income and consumption of the household and thereby reduces poverty the significant marginal value of land for both consumption and income implies that an effective land reform policy could well be an effective approach to alleviate rural poverty however land reform must come as part of a larger overhaul cluster analysis shows that land reform should target appropriate subgroups within the community in order to differentiate those who would make use of the extra land from those who would not and apply appropriate strategies to each subgroup it reveals the importance of subgroups in determining an appropriate strategy for tackling poverty

migration and income diversification evidence from burkina faso this paper uses limited dependent variable methods and new data from burkina faso to test the impact of inter continental and continental migration on activity choice and incomes in rural households econometric evidence supports our theoretical expectation that the impact of emigration varies both by migrant destination and production activity we find no evidence of either positive or negative effects of continental migration on agricultural or livestock activities and only a small negative impact on non farm activities however inter continental migration which tends to be long term and generates significantly larger remittances stimulates livestock production while being negatively associated with both staple and non farm activities

costs and benefits of livestock systems and the role of market and nonmarket relationships in developing countries livestock are kept not only for their physical products but also for insurance financing and to display status though this range of purposes is acknowledged livestock policies nevertheless often emphasize physical production a limited perspective that hampers the formulation and implementation of effective livestock policies this article presents a comprehensive appraisal of costs and benefits of livestock systems that takes into account the institutional environment of livestock keepers indicators are developed that capture quantify and organize not only the benefits resulting from the physical production but also those from the intangible functions the method is illustrated by an analysis of cattle in the western province of zambia the results indicate that the perspective on livestock systems developed more closely reflects the observed decisions of the livestock keepers

a retrospective impact evaluation of the tamil nadu empowerment and poverty alleviation pudhu vaazhvu project abstractcommunity based livelihood interventions which focus directly on increasing income and employment have become an increasingly important component of large scale poverty reduction programmes we evaluate the impact of a participatory livelihoods intervention the tamil nadu empowerment and poverty reduction pudhu vaazhvu project pvp using propensity score matching methods the paper explores the impact of pvp on its core goals of empowering women and the rural poor improving their economic welfare and facilitating public action we find significant effects of pvp on reducing the incidence of high cost debt and diversifying livelihoods we also find evidence of women s empowerment and increased political participation

poverty consumption risk and soil conservation abstract this paper studies the impact of poverty and uninsured consumption risk on incentives to invest in soil conservation a stochastic dynamic model is used to show how consumption risks and costs of investment influence incentives to adopt soil conservation measures on low income farms the model is calibrated using production data from hillside farms in the philippines simulations with the model demonstrate how the value of soil conservation depends on the cost of investing the risk characteristics of the soil conservation method and differences among households in capacity to bear risk model predictions are compared with empirical adoption patterns as described by a probit model and nonparametric kernel regressions of adoption probability empirical findings show how differences in farm size tenure security risk exposure and access to credit help to explain patterns of soil conservation adoption implications for policy are discussed

the formation of risk sharing networks this paper examines the formation of risk sharing networks in the rural philippines we find that geographic proximity possibly correlated with kinship is a major determinant of mutual insurance links among villagers age and wealth differences also play an important role in contrast income correlation and differences in occupation are not determinants of network links reported network links have a strong effect on subsequent gifts and loans gifts between network partners are found to respond to shocks and to differences in health status from this we conclude that intra village mutual insurance links are largely determined by social and geographical proximity and are only weakly the result of purposeful diversification of income risk the paper also makes a methodological contribution to the estimation of dyadic models

thar she blows gender competition and bubbles in experimental asset markets do women and men behave differently in financial asset markets our results from an asset market experiment show a marked gender difference in producing speculative price bubbles mixed markets show intermediate values and a meta analysis of 35 markets from different studies confirms the inverse relationship between the magnitude of price bubbles and the frequency of female traders in the market women s price forecasts also are significantly lower even in the first period implications for financial markets and experimental methodology are discussed jel d14 d81 g01 g11 j16

rationing and adjustment in the market for tenancies the behavior of landowning households in thanjavur district a large proportion of peasants cultivate only their own land even when there are active markets for tenancies as well as labor however rationing of tenancies can occur under moral hazard or adverse selection a model that includes as possible outcomes both rationing and full adjustment through trading is analyzed and estimated using data from south india on this basis households can be characterized as rationed or adjusted and confidence intervals for these assignments can be calculated while some households achieved full adjustment a majority were rationed in the tenancy market many of them completely

price dynamics in the bangladesh rice market implications for public intervention in this paper the price dynamics of a rice market are examined using dynamic programming techniques the model is parameterised to the case of bangladesh and thus represents the situation of a very poor country which has characteristically high price elasticity due to income effects and high storage and interest costs the incentives for private sector storage and its impact on price stability are examined various options for public intervention in the storage sector are also explored including price ceiling schemes and subsidisation of storage costs results show that interventions that remove private disincentives such as storage subsidies are much cheaper than direct intervention by government but the impact on the probability distribution of prices is quite different the effect of trade on the probability distribution of prices is also examined

sugarcane outgrowers in ethiopia forced to remain poor contract farming is often seen as a panacea to many of the challenges faced by agricultural production in developing countries given the large heterogeneity of contract farming arrangements it is debatable whether all kinds of contract farming arrangements offer benefits to participating smallholders we apply matching methods to analyze the effects of a public sugarcane outgrower scheme in ethiopia participation in the outgrower scheme significantly reduces the income and asset stocks of outgrowers who contributed irrigated land to the outgrower scheme while the effect was insignificant for outgrowers who contributed rain fed land we provide several explanations and discuss policy implications

prohibition of factor market exchanges and technological choice in chinese agriculture this article constructs a model of technological choice in an economy where market exchanges in land and labour are prohibited empirical data on demand for tractors tractor usage and chemical fertilisers in china are employed to test several hypotheses derived from the theoretical model the theory implies that the impact of relative factor scarcity on the pattern of technological choice in such an economy is similar to that in a market economy as postulated by the hicks ruttan hayami binswanger hypothesis of induced technological change the empirical evidence is found to be consistent with the implications of the model

global land investments in the bio economy evidence and policy implications for countries dependent on agriculture the recent wave of investor interest in farmland could in principle help set in motion a virtuous cycle of economic growth and poverty reduction a large literature documenting failure of such investments documents the risks involved to appreciate associated opportunities and challenges we review past experience quantify country level potential for area expansion versus intensification and identify determinants of countries attractiveness for investors in the initial stages of the land rush the fact that weak land governance seems to increase rather than reduce land demand justifies an emphasis on improving institutions transparency and accountability while at the same time providing concrete suggestions for policy and research

seasonal labor utilization in agriculture theory and evidence from agrarian households in india this paper develops and tests a dynamic stochastic model of seasonal labor demand of farm households in a developing country seasonality in agriculture is modeled as a dynamic two stage process planting and harvesting with sequential dependence of decisions yield risk is an important determinant of behavior in the planting stage only the proposed model is estimated using plot specific cross section time series data from india consistent estimates of the male and female labor demand functions in the planting and harvesting stages are obtained by panel data econometric methods that control for the nonseparability of the model

informal financial markets under liberalization in four african countries abstract this paper presents survey evidence from four countries on how informal financial agents serve market niches that banks cannot readily reach their methodologies are effective in keeping down transaction costs and default risk relative to banks although informal agents exercise monopoly power in dualistic markets liberalization of repressive financial policies has had little effect on formal financial deepening while informal finance has continued to grow the paper concludes that informal financial institutions are an important vehicle for mobilizing household savings and financing small businesses and it recommends that informal finance be better integrated into financial development strategies

does supervision matter some hypothesis tests using indian farm level data abstract a model is developed and estimated to test for heterogeneity of family and hired labor in agricultural production and to estimate the impact of employer supervision on the productivity of hired labor plot level data are used from a rice growing village in semi arid tropical india the hypothesis that family and hired labor are homogeneous inputs was rejected results indicate that family member supervision is required to increase hired labor productivity output loss attributable to operating at reduced supervision intensity was greater than 10 on over 40 of the plots

production organization and efficiency during transition an empirical analysis of east german agriculture enterprise restructuring is expected to improve efficiency in transition economies with data from former east germany we compare the efficiency of family farms and partnerships with large scale successor organizations of the collective and state farms lsos using parametric and nonparametric techniques we show that lsos display lower technical efficiency than do family farms and partnerships but that this difference is small and declining during transition mainly as a result of structural changes in agriculture family farms are not as scale efficient as partnerships and lsos and partnerships are superior to all other organizational forms

labor coercion and the accumulation of human capital abstract this paper examines the effect of labor coercion on human capital accumulation we use micro data from puerto rico where unskilled laborers were forced to work for landowners during 1849 1874 using variation in municipality level suitability for coffee cultivation and international coffee prices we estimate the response of schooling to exogenous increases in relative demand for unskilled labor in regimes with and without forced labor during the coercive regime increased coffee prices had no effect on individuals literacy rates in coffee growing regions following the abolition of forced labor in 1874 similar changes in coffee prices reduced literacy rates by 12 consistent with a diminished skill premium in the free labor market regime relative to the coercive period

migration and rural welfare the impact of potential policy reforms in europe summary this paper uses an agricultural household model in an imperfect market environment and data from burkina faso to explore the impact of potential immigration policy reforms in europe on the welfare of rural households simulation results demonstrate that in contrast to continental migration increased intercontinental migration has strong positive household welfare effects similarly an increase in the stay abroad of intercontinental migrants impacts positively on welfare of the migrant sending household results of these simulations lend support to the introduction of a tmp which would in addition to facilitating migration control in host economies improve the welfare of sending households by allowing for increased engagement in intercontinental migration the temporary nature of such a program would ensure that dutch disease effects would be mitigated through eventual migrant return

how well do tree plantations comply with the twin targets of the clean development mechanism the case of tree plantations in tanzania the clean development mechanism cdm of the kyoto protocol is supposed to provide both carbon mitigation and poverty reduction this article reports from a model based study of market related carbon leakage and poverty reduction in the wake of a cdm tree planting project in tanzania a tree plantation was incorporated in a computable general equilibrium cge model with income differentiated household segments the study focused on sensitivity of carbon leakage and income distribution to different project ownerships and carbon premium allocations it turned out that the project value in terms of carbon premium has clear shortcomings as indicator of induced gdp growth and poverty alleviation the non poor rural and urban households benefit considerably more than the poor households however rising household income in all domestic project ownership arrangements increases demand for food raises use of fertilizer and crop yields a carbon cycle module for agricultural land use was incorporated in the cge model showing an increased carbon sequestration in agricultural soil representing a negative leakage through markets in the range of 60 120 of the certified emissions reductions as registered in the cdm tree plantation project

on risk transactions and economic development in the semiarid tropics recent interest in the institutions and production relations of tropical agriculture seem to hold promise for increased collaboration between economists and anthropologists in efforts to explain existing patterns of production and socioeconomic interaction this focus on customs and on the more formal institutional arrangements is encouraging given the continuing concern for food production in much of the semiarid tropics two recent papers are particularly germane to this growing literature h p binswanger and m r rosenzweig have offered a foundation for addressing the production relations in agriculture with a general focus on conditions in south asia more recently binswanger and j mcintire provide an explanation for the major institutions and customary features of production relations in three agroclimatic subzones of the land abundant tropics that have simple technology and high transport costs 2 they also offer predictions of how these institutions and features might change in response to the opening up of subsistence economies and to population growth our approach here is consistent with this recent work in several respects first it is explanatory in that we offer possible explanations for observed behavior in the land abundant tropics where agriculture is a mixture of cropping and livestock management second it is predictive in that we draw on economic theory to hypothesize likely changes in behavior in the face of institutional change finally it is offered in the interest of stimulating a concern for the institutional preconditions of economic development by such preconditions we have in mind the institutional arrangements that can stimulate the economic development process in particular we focus on the role of transactions in the economy we do not believe that there is anything intrinsically undesirable about transactions that are restricted to a circle of family and acquaintances on the contrary such transactions play an important

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

do farmers choose to be inefficient evidence from bicol abstract farming households that differ in their ability or willingness to take on risks are likely to allocate resources and effort among income producing activities differently with consequences for productivity in this paper we measure voluntary and involuntary departures from efficiency for rice producing households in the bicol region of the philippines we take advantage of a panel of observations on households from 1978 1983 and 1994 available monthly weather data and survey information on planting times allows us to create household specific measures of weather shocks which we use in our analysis we find evidence that diversification and input choices do affect efficiency outcomes among farmers although these effects are not dominant accumulated wealth past decisions to invest favorable market conditions and propitious weather are also important determinants of efficiency outcomes among bicol rice farmers our findings suggest that the costs of incomplete formal and informal insurance markets are higher for poorer farmers

the future of small farms trajectories and policy priorities summary while smallholder development has in the past led to reductions in poverty and hunger does this still apply in today s more globalized world this paper reviews the debates on the contemporary role of agriculture in development and the case for small farms in light of the rise of supermarkets lower commodity prices and liberalized trade agricultural research funding environmental change hiv aids and changing policy ideas although the answers vary greatly by context for many low income countries smallholder development remains a key option the policy agenda however has changed in addition to providing public goods the growing challenge is to overcome market failures which is largely a matter of institutional innovation

on the costs of food price fluctuations in low income countries abstract conventional welfare measures of the costs of food price fluctuations in low income countries are extended to allow for both economic growth and food security effects the analysis reveals that growth and food security effects may dominate more conventional welfare costs of food price fluctuations although estimating the empirical magnitude of the effects is hampered by the lack of consensus on the extent to which food price fluctuations actually reduce economic growth and food security even if the welfare costs of food price fluctuations are high there are many challenges to the design and successful implementation of price stabilization schemes

the peasant in economic modernization peasants self employed tillers of soil whose farm production is based mainly on family labor as an integral part of household activities have been for thousands of years and still are today the majority of mankind their production mode represents a sharp contrast with the large internal organization of modern corporate firms characterized by a hierarchy of employees an apparently archaic style of peasant farming relative to modern corporate activities has often led to a presumption that the peasantry is a remnant of feudal society and bound to disappear as modernization proceeds as a corollary it has been argued that consolidation of peasants into large farm enterprises is desirable or necessary for promoting agricultural productivity growth consistent with modern economic development this perspective has been waning recently partly because of the disastrous experience of collective farming in former socialist economies as well as repeated failures in the attempt to develop large farms as both state and private enterprises in developing economies eicher and baker johnson and ruttan concurrently the high potential of peasants to achieve productivity growth has been recognized with the successful diffusion of modern high yielding varieties and related inputs the so called green revolution in asia yet pessimism about peasant agriculture persists and tends to distort the development strategy of the third world toward favoring large farm estates binswanger deininger and feder eicher and rukuni more ambiguous is the role of peasants in industrial and commercial development the traditional view from karl marx to w arthur

simulating the transmission of wealth inequality via bequests abstract this paper develops calibrates and simulates a dynamic 88 period olg model to study the intergenerational transmission of u s wealth inequality via bequests the model features marriage realistic fertility patterns random death assortative mating based on skills heterogeneous skill endowments heterogeneous rates of return skill inheritability progressive income taxation and resource annuitization via social security all bequests arise from imperfect annuitization nonetheless the model generates a realistic ratio of aggregate wealth to aggregate labor income a realistic bequest flow relative to the stock of wealth and a realistic wealth distribution at retirement skill differences assortative mating social security and the time preference are the primary determinants of wealth inequality bequests do propagate wealth inequality but only in the presence of social security which disproportionately disinherits the lifetime poor intergenerational wealth immobility also considered here is primarily determined by the inheritance of skills from one s parents and the magnification of the impact of this inheritance by marital sorting

local and personal networks in employment and the development of labor markets evidence from the cut flower industry in ethiopia summary we examine the roles of local and personal networks in the employment process and the emergence and development of the labor market in ethiopia s growing cut flower industry using primary survey data of 320 workers randomly sampled from all 64 farms we find that workers who were recruited informally using the social ties were paid less than the formally recruited workers at hiring however these workers quickly increased their productivity and the effect of social ties on wages disappeared over time further we find that the development of labor market for this newly emerged industry took place particularly within the industrial cluster

adaptation to land constraints is africa different since the seminal works of malthus and boserup scientists have long debated the impact of population growth and land constraints on the wellbeing of rural people today these concerns are particularly relevant to africa with its rapid population growth very small farms and chronic food insecurity in this paper we examine adaptation to falling land labor ratios using a comprehensive theoretical framework in which households faced with binding land constraints can respond in three ways intensifying agricultural production diversifying out of agriculture and reducing fertility rates using cross country data and drawing upon the existing literature we reach three conclusions first population density is associated with reduced fallows and more intensive use of land but not fertilizer use or irrigation indicating major challenges in achieving sustainable intensification or agricultural productivity growth second there is little evidence of successful non farm diversification in response to land pressures in africa from domestic or international income sources third rural africans in land constrained countries desire smaller families but have thus far benefited little from family planning policies these findings underscore the need for a coordinated multi sectoral approach to sustainably reduce poverty in the region

the role of intergenerational transfers in aggregate capital accumulation this paper uses historical u s data to directly estimate the contribution of intergenerational transfers to aggregate capital accumulation the evidence presented indicates that intergenerational transfers account for the vast majority of aggregate u s capital formation only a negligible fraction of actual capital accumulation can be traced to life cycle or hump savings a major difference between this study and previous investigations of this issue is the use of more accurate longitudinal age earnings and age consumption profiles these profiles are simply too flat to generate substantial life cycle savings this paper suggests the importance of and need for substantially greater research and data collection on intergenerational transfers life cycle models of savings that emphasize savings for retirement as the dominant form of capital accumulation should give way to models that illuminate the determinants of intergenerational transfers

landownership concentration and the expansion of education we study the relationship between large landownership concentration and the expansion of mass education in nineteenth century prussia cross sectional estimates show a negative association between landownership concentration and enrollment rates fixed effects panel estimates indicate that regions with an initially stronger landownership concentration exhibit increasing enrollment rates this relationship is not driven by differences in the supply of schooling we argue that the implementation of agricultural reforms including the stepwise abolition of serfdom is an important driver of the change in enrollment the results are consistent with the interpretation that emancipation from labor coercion increased the private demand for education

should african rural development strategies depend on smallholder farms an exploration of the inverse productivity hypothesis in africa most development strategies include efforts to improve the productivity of staple crops grown on smallholder farms an underlying premise is that small farms are productive in the african context and that smallholders do not forgo economies of scale a premise supported by the often observed phenomenon that staple cereal yields decline as the scale of production increases this paper explores a research design conundrum that encourages researchers who study the relationship between productivity and scale to use surveys with a narrow geographic reach when policy would be better served with studies based on wide and heterogeneous settings using a model of endogenous technology choice the authors explore the relationship between maize yields and scale using alternative data since rich descriptions of the decision environments that farmers face are needed to identify the applied technologies that generate the data improvements in the location specificity of the data should reduce the likelihood of identification errors and biased estimates however the analysis finds that the inverse productivity hypothesis holds up well across a broad platform of data despite obvious shortcomings with some components it also finds surprising consistency in the estimated scale elasticities

land property rights and resource allocation abstractin this paper we review the most significant empirical literature on the causal effects of land property rights the literature indicates that secure property rights boost investment in both rural and urban areas these effects however do not appear to be the result of improved credit conditions in rural areas clear land rights also lead to increases in productivity and farm earnings in contrast for urban areas the evidence for an effect on earnings is mixed we find little empirical evidence to suggest that land titling programs enhance the development of land markets finally some evidence suggests that land titling induces changes in household structure that foster human capital accumulation and may help to increase the incomes of future generations

two tier land tenure system and sustained economic growth in post 1978 rural china abstract the two tier land tenure system has been widely blamed for the problems in land allocation and in land specific investment observed in the postreform rural china greater privatization of property rights in land has been proposed to enable productive farmers to acquire more land to promote land circulation to improve farmers access to credit and to encourage farm investment it is argued here that in the presence of multiple market distortions land privatization is unlikely to provide a solution to the agricultural problems rather an approach which refines the existing framework of the two tier ownership system offers more promise

intertemporal substitution in labor supply micro evidence from rural india abstract this paper tests the hypothesis of intertemporal substitution in labor supply using time allocation data on adult male and female members of agricultural households in india the robustness of the results with respect to functional form specification and credit constraints is examined the female intertemporal elasticity of substitution is found to be significant but low similar to estimates from the us elasticity estimates for males are negative or zero tests of symmetry and additive separability proved inconclusive as they are quite sensitive to functional form in addition the empirical analysis revealed significant differences in the elasticity of substitution of females depending on land ownership and whether the period of reference falls during planting and harvesting or after harvesting these differences suggest that credit constraints limit the possibilities of substitution of labor supply across time

participation in rural land rental markets in sub saharan africa who benefits and by how much evidence from malawi and zambia we use nationally representative household level panel survey data in two neighboring countries in southern africa zambia and malawi to characterize the current status of rural land rental market participation by smallholder farmers and their subsequent welfare impacts rural rental market participation is much higher in densely populated malawi than in lower density zambia reflecting the role of land scarcity in driving rental market development consistent with previous literature we find evidence that rental markets contribute to efficiency gains within the smallholder sector by facilitating the transfer of land from less able to more able producers on average in both countries furthermore we find that rental markets serve to re allocate land from relatively land rich to land poor households we examine the impacts of participation on a number of welfare outcomes and find evidence for generally positive returns to renting in land in both countries on average however our analysis also indicates that the returns to renting in land vary strongly with scale of production tenants who produce more have larger returns to renting in and many of the smaller producers who rent in do so at an economic loss the impacts of renting out i e participating in markets as landlords are decidedly more mixed with overall negative returns to landlords in malawi and negligible returns to landlords in zambia the findings in this article highlight the need for researchers and policymakers in sub saharan africa to stay attuned to how land rental market participation and its impacts evolve in the near future

on the distribution of wealth and intergenerational transfers we develop a simple behavioral model of intergenerational transfers with individuals being subject to uncertainty about their children s incomes individuals differ with respect to innate ability and to wealth transfers they receive at birth the distributions of total wealth of total income and of their components are uniquely determined from the equilibrium distribution of intergenerational transfers for which existence and uniqueness are proven for a particular utility function and provided that earned income follows a stable law we show that so do all endogenous distributions intergenerational transfers are relatively more equally distributed than earnings capital income and lifetime wealth

rural wages labor supply and land reform a theoretical and empirical analysis land reform is one of the most mentioned of the theoretical policy instruments discussed in the development literature yet relatively little attention has been paid to the wage rate consequences of such a program despite the fact that perhaps more than one half of rural families in a developing country receive a substantial proportion of their income from wage earnings in agriculture one reason for this lacuna may be that the determination of wages and family labor supply in the agricultural sector of ldcs has also been somewhat neglected particularly in the context of a heterogeneous labor force 2 the subsistence or institutional wage models of w arthur lewis john fei and gustav ranis and gerald rodgers for instance offer no theory of how rural wage levels or differentials are set and thus provide little guidance on how wage rates would be affected by changes in land ownership patterns more recently pranab bardhan and t n srinivasan david newbery and clive bell and pinhas zusman who formulate general equilibrium market or bargaining models determining endogenously the rental share paid by tenant sharecroppers have assumed that agricultural wage rates are exogenous or determined only by nonagricultural factors all of these models assume that rural labor is homogeneous another reason why the potential wage impact of a land reform program may have received little attention is that models of peasant family behavior such as those of a k sen dipak mazumdar and robert mabro typically embody two restrictive assumptions which would tend to make the equalization of landholdings appear wage augmenting although this implication has never been formally derived these assumptions are that 1 agriculture is dualistic with small farm families facing lower shadow prices of labor leisure than large farm landlords because of impediments to labor mobility and 2 agricultural households are dichotomous small farmers employ family labor and maximize utility while large farms only utilize wage labor and maximize profits data from a 1970 71 allindia survey of over 5 000 households collected by the national council of applied economic research3 indicate however that almost all cultivator households large and small participate actively in the labor market as either buyers or sellers of labor services with almost 88 percent of households cultivating a gross cropped area less than 1 5 acres utilizing some hired labor seventynine percent of these small farm households associate professor yale ujniversity the research embodied in this paper was supported in part by a grant from the ford and rockefeller foundations program in support of social science and legal research on population policy and with funds from the u s agency for international development under order no aid otr 1432 helpful suggestions and comments were provided by james l mccabe mark gersovitz an anonymous referee the managing editor and members of the economic growth center yale university i am also grateful to the members of the research program in development studies princeton university for the use of their facilities research assistance was provided by james devine anne morgan and roberta robson inotable exceptions are r albert berry mark gersovitz and m a rahman all of these authors however employ geometric analyses with differing assumptions leading to wholly different predictions regarding wage effects none consider the heterogeneity of agricultural labor pay attention to questions of stability or attempt to apply their models to data 2lnformation on the differential impact of alternative agricultural policies including land reform on sex or age specific wage rates is not only important in settling income distribution and equity issues but as suggested in an article by the author and robert evenson may have significant implications for population growth and schooling as well 3for a more detailed discussion of these data see the author

uncertain lifetime the annuity market and estate taxation abstract this paper extends traditional studies of estate taxation to allow for the possibility that taxpayers may avoid the burden of the estate tax by strategically timing bequests to their children in this model the lifespan of the individual is uncertain and bequests can be left either in the middle or at the end of the lifespan bequests are subject to the estate tax only when they are left upon death it is shown that the effects of the estate tax depend on the ability of the individual to make intra vivos gifts which in turn is affected by the existence of a competitive annuity market

modeling spatial price transmission in the grain markets of ethiopia with an application of ardl approach to white teff following the agricultural market liberalization policy there is an emerging grain market structure in ethiopia in which the central wholesale market exhibits concentration of power and spatial integration with the local markets due to this it is hypothesized that the central wholesale market influences the long run price movements in the local markets the relationship can be modeled as spatial price equilibrium with the aim to guide subsequent policy decisions with regard to public intervention in the post liberalization period in this study we modeled the spatial equilibrium relationship between the producer and the wholesale prices of white teff a major staple in ethiopia using the autoregressive distributed lag modeling approach to cointegration analysis first the existence of a nonspurious long run relationship in levels between the producer prices in the local market and the wholesale prices in the central market is confirmed second the long run relationship and the error correction model for the producer price are estimated the results reveal that the wholesale price of white teff in the central consumer market is a major short and long run determinant of the producer price in the local supply markets therefore the institutional role of the government with the aim of improving producers marketing margin and the overall performance of the grain markets in the post liberalization period can be influenced through targeted interventions at the central wholesale market

a century long perspective on agricultural development this article strategically surveys the past century s literature on agricultural development we organize the discussion around three grand themes that reveal the richness of agricultural development as an intellectual endeavor first we explore the role of agriculture in the broader development process from a macroeconomic and political economy perspective we then examine the role of technological and institutional change in successful agricultural development finally the focus turns to a microeconomic perspective on agricultural household decision making and the problems of imperfect and missing markets asymmetric information and transactions costs that lead to widespread apparent inefficiency and disequilibrium

land tenure differences and investment in land improvement measures theoretical and empirical analyses this article develops a theoretical framework to examine the relationship between land tenure arrangements and households investment in soil improving and conservation measures it then analyzes this relationship with a multivariate probit model based on detailed plot level data from villages in the brong ahafo region of ghana a major hypothesis tested is that investment in productivity enhancing and conservation techniques are influenced by land tenure arrangements the theoretical analysis and empirical results generally reveal that land tenure differences significantly influence farmers decisions to invest in land improving and conservation measures the findings also show that tenure security does affect farm productivity

social capital human capital and the community mechanism toward a conceptual framework for economists abstract for facilitating the development of a consensus on the concept of social capital among economists this paper proposes its operational definition in a way consistent with the definitions of physical and human capital and discusses the relevance on the use of the metaphor of capital for social capital further the unique characteristics in the production and accumulation of social capital in comparison with physical and human capital are identified in relation with the community which is considered the central mechanism to produce social capital the merits and drawbacks of the community relative to the market and the state are examined with the aim of identifying the conditions under which social capital can be supplied efficiently in the direction of promoting economic progress

the family inheritance and the intergenerational transmission of inequality unequal inheritance of material wealth is commonly considered a major cause of inequality in consumption however theoretical models of the intergenerational transmission of inequality by becker blinder and ishikawa imply that unequal inheritance may either increase or reduce consumption inequality differences in inherited wealth resulting from unequal parental incomes increase inequality in recipients consumption however unequal bequests caused by differences among families in the endowed ability of children or the costs of producing human capital are equalizing empirical results confirm these predictions the inheritance received by children is inversely related to both children s income and parental education thus bequests are compensatory in that ceteris paribus low income children inherit more than their advantaged contemporaries

agricultural workers credit rationing and family networks in rural mexico abstractwe use mixed methods and first hand household data in mexico to investigate credit practices by households engaged in agricultural wage employment quantitative analysis shows evidence of rationing in the formal sector but also suggests the existence of mitigating mechanisms qualitative analysis provides additional insights first income patterns associated with agricultural wage generate income smoothing needs that are sometimes better met by the informal sector second family networks can perform key functions as gateways to the formal sector through specific informal arrangements that inject flexibility into formal rules and procedures

informal finance through land pawning contracts evidence from the philippines land pawning contracts have increased in importance in philippine rice growing villages and this article examines the determinants of choice of pawning contracts and the observed loan size the analysis shows that pawning is an informal credit instrument used by small farmers to obtain large loans to finance productive investments such as non farm employment where the returns to investment are high the econometric results suggest that poorer farm households pawn out land while wealthier farm households pawn in the observed loan size is explained by reputation of pawners and rice cropping intensity in the region

nonfarm employment agricultural shocks and poverty dynamics evidence from rural uganda this article examines the role of off farm employment in poverty reduction over a short period of time by using panel data from 894 rural ugandan households in 2003 and 2005 taking advantage of the unique off farm labor supply and income data we analyzed how households respond to negative agricultural shocks especially through off farm labor supply and income to mitigate crop income loss our analysis indicates that the flexibility of labor time allocation varies across off farm jobs and that only low skilled and low wage jobs tend to be used to mitigate negative shocks especially among the asset poor

differential adoption of modern rice technology and regional wage differential in nepal in nepal which consists of ecologically distinct regions the concentration of the adoption of modern rice varieties in the favourable rice growing areas of the country has raised fears that regional income disparities have widened this study shows that greater demand for hired labour due to the adoption of modern rice varieties has induced permanent and seasonal migration from unfavourable to favourable areas this appears to have largely equalised average wage rates across different production environments thus as far as labour income is concerned benefits from the modern varieties have been widely shared

thar she blows can bubbles be rekindled with experienced subjects we report 28 new experiment sessions consisting of up to three experience levels to examine the robustness of learning and error elimination among participants in a laboratory asset market and its effect on price bubbles our answer to the title question is yes we impose a large increase in liquidity and dividend uncertainty to shock the environment of experienced subjects who have converged to equilibrium and this treatment rekindles a bubble however in replications of that same challenging environment across three experience levels we discover that the environment yields a rare residual tendency to bubble even in the third experience session therefore a caveat must be placed on the effect of twice experienced subjects in asset markets in order for price bubbles to be extinguished the environment in which the participants engage in exchange must be stationary and bounded by a range of parameters experience including possible error elimination is not robust to major new environment changes in determining the characteristics of a price bubble jel c91 d83

bequests taxation and the distribution of wealth in a general equilibrium model this paper examines the role of bequests and of taxation on bequests for the distribution of wealth we investigate a model with overlapping generations and heterogenous households where parents derive utility directly from their bequests we obtain all results analytically using the coefficient of variation as the measure of inequality bequests per se diminish the inequality of wealth since they raise private savings and hence average wealth holdings more than the variance of wealth from a policy perspective taxing bequests and redistributing government revenue lump sum among the young generation further decreases wealth inequality

motives to remit evidence from tracked internal migrants in ethiopia summary remittances are used by households for insurance investment and income flows from internal migrants are relatively understudied in africa where migrants are less likely to remit to their origin households we use a unique matched migrant sample to study what drives the low remittance rates in ethiopia descriptive statistics suggest remitters are positively selected in terms of wealth characteristics compared with the average tracked migrant limited skill transferability and liquidity largely explain low remittance rates in ethiopia migrants are additionally motivated to remit as a form of self insurance against own shocks to income and to protect their family s productive assets

behavioural and material determinants of production relations in agriculture in this essay we develop a framework for analysing the major institutions governing the production and exchange of output and the primary factors of production in rural areas the analysis incorporates general considerations of risk and information constraints jointly with the principal material attributes of agriculture and of agricultural production factors the framework is used to analyse barriers to the existence of the major intertemporal and factor markets it is applied specifically to land scarce environments for which it provides an internally consistent explanation for many of the well documented institutional features of such settings in addition the analysis provides new implications for among other phenomena the inter relationships among ownership holdings operational scale family size and factor productivity for the scarcity of animal rental markets and use of animals as collateral for the renting out of land by small landowners and for the existence of plantations for certain crops

price stabilization liberalization and food security conflicts and resolutions abstract an important stimulus for cereal sector reform has been the massive fiscal costs of many state procurement and intervention agencies this has led to policies to minimize their role in the future through rapid market liberalization and a substantially increased role for the private sector this approach may pay insufficient attention to price stabilization and food security issues there are several instances in which even with a well developed private sector government intervention will be required to achieve adequate stability moreover where the private sector is not fully developed public sector agencies can potentially play an important but hopefully declining role in either performing or financing stabilization services international assistance could be invaluable in supporting well run intervention agencies through temporary liquidity crises cereal sector reform is a difficult process even with strong government commitment this is frequently weakened because donor agencies are unwilling to appreciate and accommodate the real fears of governments concerning their loss of control over food security as a consequence of rapid liberalization the hope is expressed that with a more measured pace and explicit concern for this issue a stronger commitment to reform might emerge

collective agricultural production a solution for transition economies abstract the paper examines theoretical reasons and provides examples for productivity differences between agricultural service cooperatives and collectives service cooperatives can utilize economies of scale enhance competitiveness and provide technical information advantages that often outweighed problems of free riding low investment and excessive political intervention agricultural collectives while not adding substantial advantages are in addition associated with problems of supervision and effort supply tendencies to substitute casual workers or mechanization for regular members and low investment incentives while collective forms of organization in transition economies respond to high risk and market imperfections they do so inefficiently policies that create conditions for service cooperatives to compete may lead to large productivity gains

an inquiry into quasi credit contracts the role of reciprocal credit and interlinked deals in small scale fishing communities in agrarian village societies beset with many hazards and uncertainties people evolve various means of coping with risk what is perhaps less known is that credit transactions can sometimes serve the function of reducing risk in such societies this article is concerned with examining several insurance motivated credit arrangements in small scale fishing communities a hunger insurance mechanism of reciprocal credit and a system of interlinked contracts aimed at insuring against risks in the spheres of labour and marketing relations will be extensively dealt with moreover the concept of triadic relationships will be shown to have special relevance in the case of traditional insurance arrangements aiming at controlling problems of moral hazard

food price policy the rationale for government intervention abstract policy makers in the most successful developing countries have not accepted either of the two major schools of thought on food price policy the neo classical school favours free trade to maximize efficiency of resource allocation the structuralist school favours interventions to satisfy goals for income distribution especially in the rapidly growing rice based economies of asia policy makers have been more concerned about stability of domestic prices than their level relative to world prices this concern traditionally dismissed by economists as purely political is justified on economic grounds because of improved macroeconomic and dynamic efficiency from stable food prices the paper identifies both the benefits from food price stability and the costs of achieving it

cattle sharing and rental contracts in an agrarian economy evidence from ethiopia empirical evidence on the role of cattle sharing and rental contracts in agrarian economies is limited this article is an investigation of different types of cattle sharing and rental contracts producers in rural ethiopia adopt it also investigates why households in rural ethiopia rely on these contracts that are vulnerable and therefore subject to potential moral hazard problems described in earlier literature we apply random effect probit and control function econometric methods to household panel data collected in 2005 and 2007 from two agro ecological zones in ethiopia controlling for the endogeneity of access to livestock credit we find that contracts are spatially fragmented and better developed where population density is high and credit and insurance markets are poorly developed we also find that contracts help cash poor and credit constrained households to improve their herd dynamics to get access to nonlivestock resources land labor and cash and share risks that could have been difficult without the contract we show that contracts are rational responses of residents in rural communities characterized by imperfect credit and insurance services since households with better access to credit are less likely to rely on contracts

rural market imperfections and the farm size productivity relationship evidence from pakistan the subject of this article is the relationships between farm size and productivity and between farm size and profitability in the developing countries the recent controversies over the inverse size output relationship are reviewed and a framework is provided that explains the inverse relationship based on plausible assumptions about imperfections in the markets for labor land credit and risk from this framework a set of testable hypotheses are derived the hypotheses are tested on recent farm level panel data from pakistan a strong inverse relationship between farm size and yield is present in the sample even when household fixed effects are used to account for unobserved heterogeneity moreover the suggested market imperfections framework is consistent with the data

is there too much hype about index based agricultural insurance abstract individual crop insurance has been largely abandoned in developing countries and replaced by insurance pilots based on weather indices these pilot schemes have encountered low demand research suggests that better off farmers may already be insured via income diversification their assets and social networks and may achieve profit maximising portfolios without formal insurance contracts they would be interested in such contracts only if they reliably reduced their exposure to risk at lower costs than their self insurance mechanisms conversely poor farmers are not able to self insure adequately have to trade off returns for reduced risk and could therefore benefit from a well designed insurance but they are cash credit constrained and therefore cannot advance the money before sowing time to buy insurance that pays out only after the harvest index insurance therefore cannot be scaled up even if a few farmers purchase it governments still will need to run relief programmes for the un
