the causes of preference reversal observed preference reversal cannot be adequately explained by violations of independence the reduction axiom or transitivity the primary cause of preference reversal is the failure of procedure invariance especially the overpricing of low probability high payoff bets this result violates regret theory and generalized nonindependent utility models preference reversal and a new reversal involving time preferences are explained by scale compatibility which implies that payoffs are weighted more heavily in pricing than in choice copyright 1990 by american economic association

rational household labor supply traditionally household behavior is derived from the maximization of a unique utility function in this paper we propose an alternative approach in which the household is modeled as a two member collectivity taking pareto efficient decisions the consequences of this assumption are analyzed in a three good model in which only total consumption and each member s labor supply are observable if the agents are assumed egoistic i e they are only concerned with their own leisure and consumption it is possible to derive falsifiable conditions upon household labor supplies from both a parametric and nonparametric viewpoint if alternatively agents are altruistic restrictions obtain in the nonparametric context useful interpretation stems from the comparison with the characterization of aggregate demand for a private good economy

marriage bequest and assortative matching in rural ethiopia abstract this article examines the determinants of human and physical capital at marriage using detailed data from rural ethiopia we find that assets brought to marriage are distributed in a highly unequal manner for first unions assets brought to marriage are positively associated with parents wealth indicating that a bequest motive affects assets at marriage parental wealth affects the inheritance of neither groom nor bride sibling competition from brothers affects grooms inheritance but sisters have no effect the marriage market is a major conduit for rural and gender inequality although avenues do exist for couples to accumulate wealth over their life cycle

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

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

green revolution land reform and household income distribution in the philippines income of agricultural households consists of returns to labor capital and land from farming supplemented mainly by labor earnings from nonfarm sources agricultural technology affects farmers income through its effect on factor demands and factor prices which in turn induce changes in the allocation of farmers own resources to different uses income from farming is also affected by village institutions such as land tenure which governs the distribution of income between landlords and tenants as well as resource allocations

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

intergenerational transfers in philippine rice villages gender differences in traditional inheritance customs abstract this paper examines education land and nonland asset transfers from parents to children in five rice villages in the philippines a model with family fixed effects explains transfers better than either individual heterogeneity or observed parent and child characteristics without family fixed effects families facing different land constraints exhibit significantly different patterns of educational investment in children in a subsample with completed inheritance daughters receive less education land and total inheritance but are compensated with nonland assets parents also exhibit preferential behavior towards children of the same gender daughters of better educated mothers receive more land nonland assets and total inheritance better educated fathers give land preferentially to sons but favor daughters in education

the economics of poverty traps and persistent poverty an asset based approach abstract longitudinal data on household living standards open the way to a deeper analysis of the nature and extent of poverty while a number of studies have exploited this type of data to distinguish transitory from more chronic forms of income or expenditure poverty this paper develops an asset based approach to poverty analysis that makes it possible to distinguish deep rooted persistent structural poverty from poverty that passes naturally with time due to systemic growth processes drawing on the economic theory of poverty traps and bifurcated accumulation strategies this paper briefly discusses some feasible estimation strategies for empirically identifying poverty traps and long term persistent structural poverty as well as relevant extensions of the popular foster greer thorbecke class of poverty measures the paper closes with reflections on how asset based poverty can be used to underwrite the design of persistent poverty reduction strategies

control and ownership of assets within rural ethiopian households this article investigates how the control and devolution of productive assets are allocated among husband and wife theory predicts that bargaining power within marriage depends on the division of assets upon divorce and on control over assets during marriage using detailed household data from rural ethiopia we show that assets brought to marriage ownership of assets control within marriage and disposition upon death or divorce are only partly related productive resources are controlled by the household head disposition upon death or divorce only loosely depends on individual ownership during marriage but control is associated with larger claims upon divorce assets brought into marriage have little impact on disposition upon death but matter in case of divorce

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

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 theory of choice and the preference reversal phenomenon a reexamination in a recent issue of this review david grether and charles plott 1979 hereinafter referred to as g p presented a series of experiments that show that individual decisions are made in a manner inconsistent with standard preference theory this inconsistency can be illustrated by the following example individuals under suitable laboratory conditions first have a choice between a lottery with a high probability of winning a small sum of money the p bet probability bet and a lottery with a high stake but low probability of winning the m bet money bet after indicating a preference for one of the lotteries in the pair the same subjects are then asked to place a monetary value on each of the individual lotteries grether and plott found that a large number of participants stated a preference for the p bet in the first round but placed a higher value on the other lottery the m bet in the second round this behavior a preference reversal is inconsistent with the traditional statements of preference theory

environmental and gender impacts of land tenure regularization in africa pilot evidence from rwanda although increased global demand for land has led to renewed interest in african land tenure few models to address these issues quickly and at the required scale have been identified or evaluated the case of rwanda s nation wide and relatively low cost land tenure regularization program is thus of great interest this paper evaluates the short term impact some 2 5 years after completion of the pilots undertaken to fine tune the approach using a geographic discontinuity design with spatial fixed effects three key findings emerge from the analysis first the program improved land access for legally married women about 76 percent of married couples and prompted better recordation of inheritance rights without gender bias second the analysis finds a very large impact on investment and maintenance of soil conservation measures this effect was particularly pronounced for female headed households suggesting that this group had suffered from high levels of tenure insecurity which the program managed to reduce third land market activity declined allowing rejection of the hypothesis that the program caused a wave of distress sales or widespread landlessness by vulnerable people implications for program design and policy are discussed

access to capital and its impact on agrarian structure and productivity in kenya access to capital and its distribution across agents can profoundly shape the structure and performance of an agrarian market economy it is conceptually useful to distinguish between ex ante and ex post capital access ex ante capital access denotes the ability of agents to finance production costs e g labor and purchased inputs costs which must be paid ex ante that is prior to the actual realization of production ex post capital access that is access to capital after the realization of the production process is of particular importance as an insurance substitute in low income agrarian economies where contingency markets are imperfect buoyant ex post capital access would permit an individual to stabilize consumption year to year even as production fluctuates annually a number of theoretical models have ex

international real business cycles among heterogeneous countries abstract business cycle statistics differ widely across countries for some aggregates especially for trade related variables part of these variations relates to the size of the economies and to their distance from each other this paper asks whether a three country model is able to display the marked diversity of business cycle statistics observed across countries the model is calibrated to two specific examples canada and switzerland our findings are that most of the diversity of the business cycles can be accounted for by size and distance and that trade is not a strong channel of diffusion of cycles

productivity health and inequality in the intrahousehold distribution of food in low income countries a model is formulated incorporating linkages among nutrition labor market productivity health heterogeneity and the intrahousehold distribution of food and work activities in a subsistence economy empirical results based on a sample of households from bangladesh indicate that despite considerable intrahousehold disparities in calorie consumption households are averse to inequality furthermore consistent with the model the results also indicate that both the higher level and greater variance in the calories consumed by men relative to women reflect in part the greater participation by men in activities in which productivity is sensitive to health status copyright 1990 by american economic association

intergenerational transfers within the family in this paper we present a stylized model of private transfers within the family under alternative assumptions as to the nature of relations between parents and children we then analyze the effectiveness of public education and social security to achieve efficiency when needed

schooling search and spouse selection testing economic theories of marriage and household behavior the implications of the economic theories of marriage and of household fertility behavior are tested in a framework in which educational investment marital search and marital matches are responsive to marriage market conditions and the personal traits of individual agents some of which are unobserved by the econometrician implications are also derived and tested for the effects of longevity attractiveness preferences and labor and marriage market conditions on schooling marriage age and spouse choice the empirical results indicate that inattention to heterogeneity and martial selection leads to a false rejection of the economic theory of marriage but to a false acceptance of the value of time fertility hypothesis

efficiency and equity impacts of rural land rental restrictions evidence from india recognition of the potentially deleterious implications of inequality in opportunity originating in a skewed asset distribution has spawned considerable interest in land reforms however little attention has been devoted to fact that in the longer term the measures used to implement land reforms could negatively affect productivity use of state level data on rental restrictions together with a nationally representative survey from india suggests that contrary to original intentions rental restrictions negatively affect productivity and equity the restrictions reduce the scope for efficiency enhancing rental transactions that benefit poor producers simulations suggest that by doubling the number of producers with access to land through rental from about 15 million currently liberalization of rental markets could have far reaching impacts

interest rates and inflation a consensus has emerged among practitioners that the instrument of monetary policy ought to be the short term interest rate that policy should be focused on the control of inflation and that inflation can be reduced by increasing short term interest rates at the center of this consensus is a rejection of the quantity theory such a rejection is a difficult step to take given the mass of evidence linking money growth inflation and interest rates increases in average rates of money growth are associated with equal increases in average inflation rates and interest rates these observations need not rule out a constructive role for the use of short term interest rates as a monetary instrument one possibility is that increasing short term rates in the face of increases in inflation is just an indirect way of reducing money growth sell bonds and take money out of the system another possibility is that while control of monetary aggregates is the key to low long run average inflation rates an interest rate policy can improve the short run behavior of interest rates and prices the shortrun connections among money growth inflation and interest rates are very unreliable so there is much room for improvement these possibilities are surely worth exploring but doing so requires new theory the analysis needed to reconcile interest rate policies with the evidence on which the quantity theory of money is grounded cannot be found in old textbook diagrams

the distributive impact of land markets in uganda abstract this article presents first hand evidence about land distribution and the impact of land markets in central uganda this area is characterized by unequal distribution of land inheritance rural rural migration and active land markets we show that land markets and particularly land purchases tend to reduce the initial inequality in the initial inherited distribution of land land purchases by landless farmers in their native village represent an important part of this adjustment

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

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

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

agricultural expansion and deforestation modelling the impact of population market forces and property rights abstract this paper compares four different modelling approaches to agricultural expansion and deforestation and explores the implications of assumptions about the household objectives the labour market and the property rights regime a major distinction is made between population and market based explanations many of the popular policy prescriptions are based on the population approach assuming subsistence behaviour and limited market integration within a more realistic particularly for the long term effects market approach well intentioned policies such as agricultural intensification programmes may boost deforestation many forest frontier contexts are also characterized by forest clearing giving farmers land rights deforestation becomes an investment to the farmer and a title establishment strategy land titling and credit programmes may therefore increase deforestation

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

preference reversals without the independence axiom the preference reversal phenomenon was believed to be inconsistent with the transitivity axiom of decision theory however recent theoretical papers have demonstrated that the preference reversals that were observed in earlier experiments could be explained by subject violations of the independence axiom or the compound lottery axiom therefore those preference reversals are not known to be inconsistent with generalization of expected utility theory that replace the independence axiom the present paper reports the results of experiments in which a substantial proportion of subject responses violate the asymmetry axiom these results are inconsistent with expected utility theory and its generalizations copyright 1989 by american economic association

monetary policy for an open economy an alternative framework with optimizing agents and sticky prices the new open economy macroeconomics seeks to provide an improved basis for monetary and exchange rate policy through the construction of open economy models that feature rational expectations optimizing agents and slowly adjusting prices of goods this paper promotes an alternative approach for constructing such models by treating imports not as finished consumer goods but rather as raw material inputs to the home economy s productive process this treatment leads to a clean and simple theoretical structure that has some empirical attractions as well a particular small economy model is calibrated and its properties exhibited primarily by means of impulse response functions the preferred variant is shown to feature a pattern of correlations between exchange rate changes and inflation that is more realistic than provided by a more standard specification important recent events are interpreted in light of the alternative models

wealth weather risk and the composition and profitability of agricultural investments despite the growing evidence that farmers in low income environments are risk averse there has been little empirical evidence on the importance of risk in shaping the actual allocation of production resources among farmers differentiated by wealth the authors use panel data on investments in rural india to examine how the composition of productive and nonproductive asset holdings varies across farmers with different levels of total wealth and across farmers facing different degrees of weather risk income variability is a prominent feature of the experience of rural agents in low income countries the authors report evidence based on measures of rainfall variability that the agricultural investment portfolio behavior of farmers in such settings reflects risk aversion due evidently to limitations on consumption soothing mechanisms such as crop insurance or credit markets the authors results suggest that uninsured weather risk is a significant cause of lower efficiency and lower average incomes a one standard deviation decrease in weather risk measured by the standard deviation of the timing of the rainy season would raise average profits by up to 35 percent among farmers in the lowest wealth quartile moreover rainfall variability induces a more unequal distribution of average incomes for a given distribution of wealth wealthier farmers are willing to absorb significant risk without giving up profits to reduce production risk smaller farmers have to invest their limited wealth in ways that reduce their exposure to risk at the cost of lower profit rates the authors found that at high levels of rainfall variability differences in rates of profit per unit of agricultural assets were similar across classes of wealth but over the sample range of rainfall variability these rates of profit were always higher for the poorer farmers than for the wealthier ones suggesting that the disadvantages of small farmers in risk diffusion are more than offset by their labor cost advantage

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

dynamics of the trade balance and the terms of trade the j curve the authors provide a theoretical interpretation of two features of international data the countercyclical movements in net exports and the tendency for the trade balance to be negatively correlated with current and future movements in terms of trade but positively correlated with past movements they document the same properties in a two country stochastic growth model in which trade fluctuations reflect in large part the dynamics of capital formation the authors find that their general equilibrium perspective is essential the relation between the trade balance and the terms of trade depends critically on the source of fluctuations copyright 1994 by american economic association

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

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

preference reversal real world lotteries and lottery interested subjects prefer lce reversal or choice reservation price inconsistency has been documented experimentally for zrtain types of lotteries we argue that the relevance of these findings for realworld markets is uncertain because the type of objects used cannot exist on a market and because the extent to which the subjects had any real interest in the objects is unknown using reai world lotteries we have tested choice price consistency on subjects who prefer lotteries ta cash preference reversal was observed but the frequency was much lower than in earlier experiments there were no differences between subjects who qualified as lottery interested and those who did not 1 intmduction

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

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

land inheritance rules theory and cross cultural analysis abstract this paper develops a general theory of land inheritance rules that distinguishes between two classes of rules those allowing a testator discretion in disposing of his land e g a best qualified rule and those constraining his choice e g primogeniture the primary benefit of the latter is to prevent rent seeking by heirs but the cost is that the testator cannot use information about the relative abilities of his heirs to manage the land we also account for the impact of scale economies in land use and discuss the impact of the presence of a land market on the form of the inheritance rule we conclude by offering some empirical tests of the model using a cross cultural sample of societies

choice under uncertainty evidence from ethiopia india and uganda we review experimental evidence collected from risky choice experiments using poor subjects in ethiopia india and uganda using these data we estimate that just over 50 of our sample behaves in accordance with expected utility theory and that the rest subjectively weight probability according to prospect theory our results show that inferences about risk aversion are robust to whichever model we adopt when we estimate each model separately however when we allow both models to explain portions of the data simultaneously we infer risk aversion for subjects behaving according to expected utility theory and risk seeking behaviour for subjects behaving according to prospect theory

intra household resource allocation an inferential approach if household income is pooled and then allocated to maximize welfare then income under the control of mothers and fathers should have the same impact on demand with survey data on family health and nutrition in brazil the equality of parental income effects is rejected unearned income in the hands of a mother has a bigger effect on her family s health than income under the control of a father for child survival probabilities the effect is almost twenty times bigger the common preference or neoclassical model of the household is rejected if unearned income is measured with error and income is pooled then the ratio of maternal to paternal income effects should be the same equality of the ratios cannot be rejected there is also evidence for gender preference mothers prefer to devote resources to improving the nutritional status of their daughters fathers to sons

motives for private income transfers private income transfers are becoming increasingly recognized as a key aspect of the u s economy the majority of private income transfers occur inter vivos i e between living persons but very little is known about this type of transfer behavior this paper tests alternative hypotheses concerning motivation for inter vivos transfers two motives are considered altruism and exchange evidence presented here casts doubt on the altruistic model of transfer behavior observed patterns for inter vivos transfers are more consistent with exchange related motives this finding has important implications for the effects of public transfer programs on the distribution of economic well being

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 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

shadow wages allocative inefficiency and labor supply in smallholder agriculture this article introduces a method for estimating structural labor supply models in the presence of unobservable wages and deviations of households marginal revenue product of self employed labor from their shadow wage this method is therefore robust to a wide range of assumptions about labor allocation decisions in the presence of uncertainty market frictions locational preferences etc we illustrate the method using data from rice producers in cote d ivoire these data like previous studies reveal significant systematic differences between shadow wages and the marginal revenue product of family farm labor we demonstrate how one can exploit systematic deviations in the present case related to household characteristics such as the land labor endowment ratio to control for both unobservable wages and prospective allocative inefficiency in labor allocation in structural household labor supply estimation

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

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

an analysis of sample attrition in panel data the michigan panel study of income dynamics by 1989 the michigan panel study on income dynamics psid had experienced approximately 50 percent sample loss from cumulative attrition from its initial 1968 membership we study the effect of this attrition on the unconditional distributions of several socioeconomic variables and on the estimates of several sets of regression coefficients we provide a statistical framework for conducting tests for attrition bias that draws a sharp distinction between selection on unobservables and on observables and that shows that weighted least squares can generate consistent parameter estimates when selection is based on observables even when they are endogenous our empirical analysis shows that attrition is highly selective and is concentrated among lower socioeconomic status individuals we also show that attrition is concentrated among those with more unstable earnings marriage and migration histories nevertheless we find that these variables explain very little of the attrition in the sample and that the selection that occurs is moderated by regression to the mean effects from selection on transitory components that fade over time consequently despite the large amount of attrition we find no strong evidence that attrition has seriously distorted the representativeness of the psid through 1989 and considerable evidence that its cross sectional representativeness has remained roughly intact

does exchange rate stability increase trade and welfare we develop a simple general equilibrium framework to study the effect of the exchange rate system on trade and welfare an important feature of the model is deviations from purchasing power parity caused by rigid price setting in buyers currency we find the following first exchange rate stability is not necessarily associated with more trade in a simple benchmark model with separable preferences and only monetary shocks trade is unaffected by the exchange rate system consistent with most evidence second both trade and welfare can be higher under either exchange rate system depending on preferences and on the monetary policy rules followed under each system finally in general there is no one to one relationship between the levels of trade and welfare across exchange rate systems

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

preference reversals the impact of truth revealing monetary incentives researchers vigorously debate the impact of incentives in preference reversal experiments do incentives alter behavior and generate economically consistent choices lichtenstein and slovic 1971 document inconsistencies reversals in revealed preference in gamble pairs across paired choice and individual pricing tasks the observed pattern is inconsistent with stable underlying preferences expressed with simple errors lichtenstein and slovic 1973 and grether and plott 1979 introduce incentives but aggregate reversal rates change little these results fostered numerous replications and assertions that models of non stable preferences are required to explain reversals contrary to this research we find that incentives can generate more economically consistent behavior our reevaluation of existing experimental data shows that incentives have a clear impact by better aligning aggregate choices and prices the effect is sufficiently large that with truth revealing incentives a stable preferences with error model not only explains behavior but fits the data as well as any model possibly could

the empirical content of nash bargained household behavior in households whose allocation decisions can be represented as nash bargained household decisions extrahousehold environmental parameters eeps serve as pure shifters of the threat points the comparative statics of changes in demands due to changes in these eeps are given these are incorporated into a comprehensive statement of the empirical content of nash bargained household behavior including a nash generalization of barten s 1966 fundamental matrix equation of the theory of consumer demand estimation and data requirements are discussed along with nested testing of the following structure the neoclassical model is nested in the nash bargained model which in turn is nested in an unrestricted model of household demands emphasized throughout is the enriched menu of explanatory variables for demand analysis provided by the nash model as well as the model s ability to jointly analyze i household formation and ii intrahousehold allocation decisions

naturally occurring markets and exogenous laboratory experiments a case study of the winner s curse we examine the relevance of experimental findings from laboratory settings that abstract from the field context of the task that theory purports to explain using common value auction theory as our guide we identify naturally occurring settings in which one can test the theory experienced agents bidding in familiar roles do not fall prey to the winner s curse yet experienced agents fall prey to the winner s curse when bidding in an unfamiliar role we conclude that the theory predicts field behaviour well when one is able to identify naturally occurring field counterparts to the key theoretical conditions

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

gender bias investments in children and bequests the impacts of pure sex preference and differential earnings opportunities by gender on investments in children are modelled with altruism if bequest constraints do not bind human investments are privately efficient with the higher earning gender receiving more education education does not depend on parental wealth the gender differential in bequests is ambiguous however even in this case when bequest constraints bind education may depend on wealth and it is also possible for the gender with better earnings opportunities to get less education the model is tested with data from philippine villages where bequest constraints are generally nonbinding the schooling differential slightly favors daughters estimated bequest behavior however reflects pure sex preference in terms of our model copyright 1995 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

theory and misbehavior of first price auctions recent experimental evidence appears to reject simple nash equilibrium models of bidding behavior in first price auctions the author presents a methodological critique of this evidence existing tests have concentrated on deviations of subjects from predictions in the message space of the action bid deviations the author suggests that it is more natural to evaluate subject behavior in expected payoff space he concludes that the evidence against the simple models is not significant enough to warrant their rejection copyright 1989 by american economic association

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

child labor and household wealth theory and empirical evidence of an inverted u some studies on child labor have shown that at the level of the household greater land wealth leads to higher child labor thereby casting doubt on the hypothesis that child labor is caused by poverty this paper argues that the missing ingredient may be an explicit modeling of the labor market we develop a simple model which suggests the possibility of an inverted u relationship between land holdings and child labor using a unique data set that has child labor hours it is found that controlling for child household and village characteristics the turning point beyond which more land leads to a decline in child labor occurs around 4 ac of land per household c 2009 published by elsevier b v

risk rationing and wealth effects in credit markets theory and implications for agricultural development we develop a model that shows that asymmetric information can result in two types of credit rationing conventional quantity rationing and risk rationing whereby farmers are able to borrow but only under high collateral contracts that offer them lower expected well being than a safe subsistence activity after exploring its incidence with respect to wealth we show that risk rationing has important policy implications specifically land titling will be only partially effective because it does not enhance producers willingness to offer up the collateral needed to secure loans under moral hazard constraints efforts to enhance agricultural investment and the working of agricultural credit markets must step beyond land titling and also deal with risk copyright 2008 oxford university press

assets activities and rural income generation evidence from a multicountry analysis summary this paper examines the links between the assets and the economic activities of rural households in developing countries to provide insight into how the promotion of certain key assets particularly education land and infrastructure influences the economic choices of these households nationally representative data from 15 countries which form part of the rural income generating activities riga database are used in the analysis the results indicate that improved land access is linked to agricultural production and thus will lead households to take on average this path for improving household welfare higher levels of education and greater access to infrastructure appear to be most closely linked to non agricultural wage employment
