marketed surplus under risk do peasants agree with sandmo using a newly defined notion of aversion to income risk the behavior of the marketed surplus producer under price risk is characterized unlike the familiar case first examined by sandmo output depends on both ordinal preferences for goods and on risk attitudes conditions are found that yield an output level under risk that is smaller than under certainty if these conditions do not hold both risk and risk aversion may have a positive effect on output implications for econometric studies of risk attitudes are considered and illustrated with an example finally we examine the effect of uncertainty on the peasant s long run equilibrium

post reform forestland markets in china land markets developed rapidly in china after agricultural land tenure reforms but not after forest reforms we surveyed farmers in three provinces to examine the post reform forestland markets and options to strengthen them using household choice experiments we estimate land market demand and supply under alternative contractual arrangements our findings are consistent with the currently thin markets but also suggest that alternative institutional and contractual conditions could support broader participation in land markets strengthening property rights on forestland emerges as an especially effective possible policy instrument we illustrate its predicted effects on equilibrium rental rates and market participation

land rental development via institutional innovation in rural jiangsu china previous studies have demonstrated that there are two important preconditions for encouraging land rental in agriculture out migration and the enhancement of security and transferability of land rights focusing on the latter we scrutinize the impacts of institutions aimed at facilitating land use dynamism particularly the rural shareholding cooperatives rscs which have been established recently at the local level in rural china in general we find that rscs can pave the way for the extension of property rights to farmland and promote more efficient land use patterns using survey data collected from 300 village committees in rural jiangsu province we estimate the effectiveness of rscs in encouraging land rental our analysis reveals that rscs can serve as intermediate agents for reducing transaction costs associated with exchange of land use rights and thereby not only encourage land rental consolidation activities but also enable the entry of non farm household entities into the farm business

agricultural household models extensions applications and policy this book presents the basic model of an agricultural household that underlies most of the case studies undertaken so far the model assumes that households are price takers and is therefore recursive the decisions modeled include those affecting production and the demand for inputs and those affecting consumption and the supply of labor comparative results on selected elasticities are presented for a number of economies the empirical significance of the approach is demonstrated in a comparison of models that treat production and consumption decisions separately and those in which the decisionmaking process is recursive the book summarizes the implications of agricultural pricing policy for the welfare of farm households marketed surplus the demand for nonagricultural goods and services the rural labor market budget revenues and foreign exchange earnings in addition it is shown that the basic model can be extended in order to explore the effects of government policy on crop composition nutritional status health saving and investment and to provide a more comprehensive analysis of the effects on budget revenues and foreign exchange earnings methodological topics primarily the data requirements of the basic model and its extensions along with aggregation market interaction uncertainty and market imperfections are discussed the most important methodological issues the question of the recursive property of these models is also discussed

sales location among semi subsistence cassava farmers in benin a heteroskedastic double selection model in much of rural africa high transaction costs limit farmers market participation and thus their potential for income growth transaction costs can affect not only whether a farmer sells product but also whether sales occur at the farm gate or at a market if production behavior is related to a chosen sales location then analysis of interventions can be improved by explicit consideration of the decision of where to sell this article develops a double selection model that explains consumption and production decisions by semi subsistence farmers who first decide whether to be a seller and then whether to sell at the farm gate or at an off farm location before deciding on production and consumption the study tests the validity of this dual criteria model against a single criterion model in which a grower first decides to be a seller and then decides production consumption and sales location simultaneously the results suggest that the dual criteria model provides more information than the single criterion model using a sample of cassava producer in benin

local versus global separability in agricultural household models the factor price equalization effect of land transfer rights commonly employed global tests for separability between production and consumption decisions are theoretically inappropriate when the market failures creating non separabilities differentially constrain some but not all households simulated maximum likelihood estimates using chinese panel data reject the restrictions implied by a global separability test in favor of regime specific or local separability tests the estimates also show that a global approach to separability obscures the significant effect that less encumbered land transfer rights would have on shadow factor price equalization across households and allocative efficiency the findings on transfer rights suggest a resolution to the debate in china on further property rights reform copyright 2002 oxford university press

a farm household model for agri food policy analysis in developing countries application to smallholder farmers in sierra leone this paper presents a generic farm household model for use in the context of developing countries to gain knowledge on food security and rural poverty alleviation under different policy options it is a static positive programming model which simultaneously solves a set of microeconomic farm models reproducing the behaviour of representative individual farm households this model is designed to capture key features of developing countries agriculture such as the non separability of production and consumption decisions due to market imperfections the inter linkage between transaction costs and market participation decisions the interaction among farm households for factor markets and the seasonality of resource use model use is illustrated in this paper by simulating the impact of rice seed policy on the livelihood of representative smallholder farmers in sierra leone results show that the seed policy would improve farm productivity and boost household income but that it is not sufficient to fight poverty since 90 of the surveyed farm households would continue to live below the extreme poverty line of 1 usd equivalent per person per day

equilibrium selection observability and backward stable solutions abstract the robustness of stability under learning to observability of exogenous shocks is examined regardless of observability assumptions the minimal state variable solution is robustly stable under learning provided the expectational feedback is not both positive and large while the nonfundamental solution is never robustly stable overlapping generations and new keynesian models are considered and concerns raised in cochrane 2011 2017 are addressed

estimating labor supply and production decisions of self employed farm producers abstract this paper proposes a model oriented towards integrating farm households production and consumption decisions into a unified theoretical and econometric framework it is argued that in contrast with other forms of economic organization farm households utility and profit maximization decisions are not likely to be independent econometric estimation of a farm household model using canadian data suggests that utility and profit maximizing decisions are not indeed independent and moreover that there are significant gains in explanatory power and efficiency by estimating the consumption and production equations jointly

cash crop production food price volatility and rural market integration in the third world large farmers in the third world often devote to cash crops a larger share of their land than do small farmers this paper suggests a possible explanation even in the presence of food markets third world farmers food security is best assured by food self sufficiency a model of crop portfolio choice under multivariate risk is used to show that reasonable assumptions regarding risk and preferences reproduce the observed pattern simulations further indicate that food market integration reduces the need for food self sufficiency policy implications are drawn regarding domestic trade liberalization and agricultural technology

tax policies and the financially constrained farm household this article analyzes the implications of income profit and consumption taxes on the economic decisions of financially constrained farm households within a dynamic intertemporal framework the most important results are that replacing a profits tax with a consumption tax would lead to increases in on farm work farm income and farm production in the short run capital accumulation would be enhanced leading to similar effects in the long run if an income tax is replaced with a consumption tax similar expansive effects would occur in the intermediate and long run but in the short run there would be no effect on farm production

structural agricultural land use modeling for spatial agro environmental policy analysis this paper develops a spatially disaggregated structural econometric model of agricultural land use and production based on the joint multi output technology representation introduced by chambers and just 1989 starting from a flexible specification of the farm profit function we derive land use allocation input application crop yield and livestock intensity equations in a joint and theoretically consistent framework to account for the presence of censored observations in micro level data the model is estimated as a system of two limit tobit equations via quasi maximum likelihood we present an empirical application using fine scale spatial data covering the entirety of england and wales and including the main economic policy and environmental drivers of land use change in the past forty years a simulation of the effects of diffuse pollution reduction measures illustrates how our approach can be applied for agro environmental policy appraisal

endowments technology and factor markets a natural experiment of induced institutional innovation from china s rural reform the induced institutional innovation hypothesis postulates that new institutions are innovated to exploit profitable opportunities arising from institutional disequilibrium the removal of legal restrictions on factor market exchanges after recent reforms in china resulted in institutional disequilibrium this paper utilizes data from a household survey in china to explore i the relationship between the emergence of land labor and rental markets in a region and the distribution of factor endowments across rural households in that region and ii the impact of hybrid rice on the emergence of factor markets in that region the results are consistent with the induced institutional innovation hypothesis

the diversity of land markets and regulations in europe and some of its causes abstractthe creation of optimal land institutions attracted renewed attention in the 1990s because of its central role in the transition process in former communist countries in the former soviet union and eastern europe and more recently because of large scale land investments in developing countries this article documents the existence of large variations in land institutions markets and regulation using current and historical data from western and eastern europe it then offers explanations for these differences and draws implications for the role and optimality of land institutions in development with special reference to the current debate on large scale land acquisitions

land tenure choice in chinese villages the rational versus the political model the rational and political decision models are developed and tested for the land tenure choice in rural china a novelty of the test is to link the collective decision with general relative factor scarcities competing hypotheses are developed for the two models and tested with panel data collected on 83 chinese villages the results show that neither model is strongly rejected although the political model fares slightly better in more sophisticated econometric testing this suggests that popular political participation is emerging in chinese villages implications of this finding to chinese land policy are discussed

access to capital and agrarian production organisation there are two problems both universal that entrepreneurs in any economy must contend with firstly an agent generally has access only to a limited amount of working capital secondly workers hired by an agent are subject to moral hazard and this necessitates their supervision this paper models for an agrarian economy the constraints imposed on entrepreneurs activities by these two problems and endogenously determines the various organisational forms of production as well as the allocation of resources that will obtain with a simple model we endeavour to explain a diverse set of empirical observations pertaining to the less developed countries in terms of the general processes that determine the distribution of income among the various agents and the hierarchical relationships that develop among them agricultural production typically involves a period of several months between the time the inputs are purchased and the time the output is marketed access to working capital and hence to the credit market thus plays an important role in a farmer s production decisions the distribution of access to credit in turn tends to be an important determinant of income distribution in poor agrarian economies credit is invariably rationed according to the ability to offer collateral the amount of working capital a farmer can mobilise therefore depends on the amount of land he owns which is often a good proxy for his overall wealth and thus his ability to offer collateral further since hired hands have a propensity to shirk they need to be supervised and therefore the

household resources transaction costs and adjustment through land tenancy this paper examines the role of household endowments of imperfectly tradeable factors of production e g male female child labor and draft animals on land leasing an explicit attempt is made to account and test for the role of transaction costs on the incidence and extent of adjustment taking place through the land lease market the econometric model is implemented using pooled data from six villages in the semiarid region of india the results confirm the significant role of nontradeable family endowments and indicate the presence of frictions in the land tenancy market

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

peasant household behaviour with missing markets some paradoxes explained a model of peasant household behavior under varying degrees of household specific food and labor market failures is constructed to show that these structural features can explain several well known patterns of peasant response which have often been attributed to peculiar motives presumed specific to peasants the model explains sluggish response to cash crops prices and high instability in perceived food and labor scarcities the key role of manufactured consumer goods prices in stimulating peasants effort in cash crops production the effectiveness of taxation as opposed to incentives in stimulating cash crops production and the key role of technological change in food production to enhance cash crop production results are obtained analytically in the case of one market failure and by numerical simulation with more than one

using shadow wages to estimate labor supply of agricultural households with few exceptions most studies of the labor demand and supply decisions of agricultural households in developing countries have relied on the empirical advantages of separability given the questionable nature of some of the assumptions sufficient for separability i apply a recent methodology that accounts for the simultaneity between the production and consumption decisions of a farm household using data from rural india direct estimates of the marginal productivities shadow wages of family male and female labor are derived from a cobb douglas agricultural production function the estimated shadow wages and income are then used as regressors in a structural model of labor supply

tenancy and family resources a model and some empirical analysis abstract in this paper we discuss with the help of a simple model the role of family resource endowments in determining the extent of land leased in or leased out by a household this becomes important when the market for some of these resources is either not functioning at all or is functioning imperfectly we focus on three such resources which have some relevance in indian agriculture these are 1 the family s managerial skill 2 its endowment of human labour and 3 its endowment of draft animal labour household level data from six villages of maharashtra and andhra pradesh are also utilized to test some of the hypotheses

transactions costs and agricultural household supply response we develop and estimate a model of supply response when transactions costs create a situation where some producers buy others sell and others do not participate in markets we present two rationales for why producing households may have different relationships to the market proportional and fixed transactions costs using data on mexican corn producers we estimate an empirical model that allows for separate tests of the significance of both types of transactions costs revealing that both fixed and proportional transactions costs matter for the estimation the results provide consistent estimates of supply elasticity and measures of the relative importance of factors determining both proportional and fixed transactions costs

land inheritance and market transactions in uganda studies on the role of nonmarket land transactions remain limited this paper addresses two questions is land inheritance driven by underdeveloped land markets how does land inheritance influence land disposal and acquisition we use a switching regression model on household data from rural uganda we find that the initially landless or near landless households due to little or no land inheritance obtain land through land markets while those that are land rich dispose of land through land sales and bequests the results suggest that a process of land equalization is unfolding within the sample

food price changes and household welfare what do we learn from two different approaches the use of a marginal approach can significantly distort the predicted effects of large price variations on monetary welfare over the medium to longer term this paper aims at shedding some light

transport costs and smallholder cropping choices an application to siaya district kenya smallholders regularly devote shares of resources to low yielding food crops than they do to cash crops that have higher market returns in this paper costly exchange is incorporated into an agricultural household model and a numerical nonseparable version of the model is used to show that seemingly inefficient cropping choices of this type in siaya district kenya can be explained as rational food import substitution given high transport costs in product markets improved rural road networks that reduce these costs could abate motives to meet food needs through domestic production and promote specialization that raises farm incomes

household composition labor markets and labor demand testing for separation in agricultural household models this paper tests the separation of farm labor supply and labor demand decisions using the observation that household composition is an important determinant of farm labor use with nonseparation after assessing the conditions under which the test has power against several alternatives an empirical model is developed to test the proposition that farm employment is independent of family composition the model is estimated on a data set from rural java the null hypothesis that farm labor allocation decisions are independent of household structure is not rejected the results are robust to different specifications of the labor demand function copyright 1992 by the econometric society

determinants of nonfarm earnings of farm based husbands and wives in northern ghana the nonfarm work participation decisions of married men and women in rural northern ghana were jointly and separately estimated for married couples through a bivariate probit using recent survey data selectivity bias was corrected for in estimating wage offer and labor supply equations using heckman s procedure education experience infrastructure distance to the capital and population density as well as interactions between education and infrastructure and between education and distance to the city were found to be significantly related to the probability of nonfarm labor market participation wages and the amount of nonfarm labor performed with significant differences by gender

the development of the land lease market in rural china this paper examines the development of the land lease market in rural china special attention is paid to productive heterogeneity among farmers and the openness of the labor market in activating the land lease market a theoretical model is employed to explore the underlying connections an econometric model is implemented using a two period panel data set gathered in three counties of china s zhejiang province the results show that productive heterogeneity and a freer labor market do promote more land leases the implications for the institutional change literature are discussed

modeling farm households price responses in the presence of transaction costs and heterogeneity in labor markets we develop a farm household model to analyze price responses of farm households this model incorporates various types of transaction costs as well as labor heterogeneity nonproportional variable transaction costs or labor heterogeneity imply that production and consumption decisions become nonseparable even when the household buys or sells labor an empirical model is estimated using data from midwest poland the results show that nonproportional variable transaction costs and labor heterogeneity significantly influence household behavior not all price elasticities however change significantly if these are neglected

the effects of china s sloping land conversion program on agricultural households in the late 1990s china aimed to mitigate environmental degradation from agricultural production activities by introducing the world s largest payments for environmental services pes program the sloping land conversion program slcp in order to analyze its effects on agricultural households we develop a microeconomic agricultural household model ahm which can model the production consumption and non farm labor supply decisions of agricultural households in rural china in a theoretically consistent fashion based on this theoretical model we derive an empirical specification that we use to econometrically estimate the effects of the slcp and other exogenous factors using a large longitudinal farm household survey data set we estimate the empirical model with the hausman taylor estimation method the empirical results are generally consistent with the results of our theoretical comparative static analysis e g that the slcp significantly decreases agricultural production while the slcp increases non farm labor supply and total consumption in the yellow river basin these effects could not be observed in the yangtze river basin the recent reduction of the slcp compensation payment rates has had some notable but generally small effects

shadow wages and peasant family labour supply an econometric application to the peruvian sierra a striking feature of developing economies is the large proportion of the work force that is self employed lack of widespread labor market participation in the agricultural sector can pose a major obstacle to the empirical implementation of economic models of the peasant household whether because wage data are simply not available or because the assumptions required to make use of wage data stretch the bounds of credulity this paper develops a methodology for estimating a structural labor supply model for primarily self employed peasant households which holds under a general agricultural technology and set of labor market conditions the unique feature of the approach is that the opportunity cost of time or shadow wage of household workers is explicitly estimated from an agricultural production function and is subsequently used to identify a set of structural labor supply parameters recent household survey data from rural peru is employed to estimate and perform various diagnostic tests on the model the empirical findings lend support to the hypothesis that peasant households allocate their members time as if to maximize a family utility function and moreover demonstrate the tractability of the shadow wage methodology and its usefulness in estimating more elaborate time allocation models

the potential of land rental markets in the process of economic development evidence from china abstract we develop a model of land leasing with agents characterized by unobserved heterogeneity in ability and presence of an off farm labor market in this case decentralized land rental may contribute to equity and efficiency goals and may have several advantages over administrative reallocation the extent to which this is true empirically is explored using data from three of china s poorest provinces land rental markets and administrative reallocation reallocate land to those with lower endowments but the former are more effective in doing so and have a bigger productivity enhancing effect information on hypothetical market participation suggests that reducing transaction costs in land rental markets could help to realize significant additional productivity gains

a symmetric normalized quadratic gnp function and the u s demand for imports and supply of exports this paper reports estimates of a gnp function for the united states using data covering most of the postwar period and it introduces a new functional form the symmetric normalized quadratic variable profit function which is a natural extension of recent work by diewert and wales this functional form allows convexity in prices and concavity in fixed inputs to be imposed globally empirical results indicate that the demand for imports is less price elastic than the supply exports that an increase in labor endowment favors trade and that a deterioration of the terms of trade mostly hurts labor

rural industry and labor market integration in eastern china abstract this paper tests the competitiveness of the labor market in a semi industrialized county located in eastern china labor market segmentation is linked to the degree of government interventions and the management structures of the local enterprises and two forms of rationing labeled entrance and time rationing are identified a test based on income maximizing behavior is developed to find the form of rationing that is consistent with the data the results show that the labor market is not competitive and time rationing prevails in the county in addition industrial wages are not responsive to experience and education but strongly biased against women and varying to government interventions

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

labor migration and returns to rural education in china this paper provides an answer to the following question why do empirical studies find low returns to schooling in rural china and yet the schooling rates are high i find that schooling played a significant role in raising the accessibility of urban formal employment to rural people in the late 1970s and early 1980s in the face of the government s restrictive policy on labor migration from rural to urban areas the large urban rural income difference provided a strong incentive for senior high school education the theory also explains the drop in the senior high school attendance in the mid 1980s

food insecurity income inequality and the changing comparative advantage in world agriculture i would like to argue in this article that in the process of economic development in land poor countries in asia agriculture faces three distinctly different problems food insecurity sectoral income inequality and the declining food self sufficiency associated with the declining comparative advantage in agriculture at the high income stage massive imports of food grains to asia if they occur will aggravate the world food shortage which will have significant implications for the poverty incidence in the world i argue that in order to avoid such a tragedy asia should expand farm size to reduce labor cost by adopting large scale mechanization sub saharan africa should realize a green revolution in grain production and latin america should further expand its grain production capacity

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

land rental markets in transition theory and evidence from hungary summary this paper analyzes the determinants of household farms participation in land rental markets in transition countries we derive several hypotheses on the impact of households human capital land endowment land quality and prices transaction costs rural credit and labor market constraints our empirical analysis uses data from a representative survey of more than 1 400 hungarian household farms and hungarian official statistics land rental markets reallocate land to households with better farm management capacities households combine buying and renting of land to extend their farms land ownership is fragmented and land consolidation occurs through renting the domination of corporate farms in some regions restricts households access to land

the relation between farm size and farm productivity the role of family labor supervision and credit constraints abstract the paper shows that if the performance of hired farmhands is affected by supervision from family members and if the availability of credit is dependent on the amount of land owned then a systematic positive or negative relationship between per acre yields and farm size will prevail a model with no supervision effects on labor productivity would predict that yields are unaffected by farm size the paper also investigates the relation between land utilization and owned holding size when land rental possibilities are limited results are shown to be compatible with various observed patterns in ldcs
