stacking up the ladder a panel data analysis of tanzanian household energy choices energy use statistics in tanzania reflect the country s low level of industrialization and development in 2016 only 16 9 of rural and 65 3 of urban inhabitants in mainland tanzania were connected to some form of electricity we use a nationally representative three wave panel dataset 2008 2013 to contribute to the literature on household energy use decisions in tanzania in the context of the stacking and energy ladder hypotheses we firstly adopt a panel multinomial logit approach to model the determinants of household cooking and lighting fuel choices secondly we focus explicitly on energy stacking behaviour proposing various ways of measuring what is inferred when stacking behaviour is thought of in the context of the energy transition and presenting household level correlates of energy stacking behaviour thirdly since fuel uses have gender differentiated impacts we investigate women s bargaining power in the decision making process of household fuel choices we find that whilst higher household incomes are strongly associated with a transition towards the adoption of more modern fuels especially lighting fuels this transition takes place in a context of significant fuel stacking in tanzania government policy has been aimed mostly at connecting households to the electric grid however the public health environmental and social benefits of access to modern energy sources are likely to be diminished in a context of significant fuel stacking lastly we present evidence that the educational attainment of women in the household is an important aspect of household fuel choices

child fostering in africa when labor and schooling motives may coexist abstract the paper proposes a theoretical framework for understanding purposive child fostering in africa whereby a non orphaned child is sent to live temporarily with relatives in the model adults decide whether to foster in or out a child in conjunction with other household choices e g own time allocation between market and non market activities children s amount of work and schooling by allowing for positive externalities from fostering and thus asymmetric motives for fostering in labor and out human capital the proposed framework predicts that school age children are sent to better off households and that some families may foster in and out simultaneously the model identifies the conditions under which all actors involved children included may benefit from fostering arrangements but also points to situations where fostering may become an opportunity to marginalize a subset of children the paper aims to provide a sound theoretical foundation that sheds light on why there exists mixed empirical evidence on the effects of fostering on children s well being and cautions against demonizing non parent residence as unequivocally detrimental to children

agricultural policy decisions in the ec consequences of institutional imbalance abstract in almost all developed countries agriculture is protected by state interventions of a differing nature and degree subject to political decisions these decisions are determined by the institutional framework of the relevant decision making process in this article it is demonstrated that the institutional framework of the ec differs to a large degree from those in most parliamentary democracies such institutional peculiarities favour the transformation of political interests of farmers into decisions on farm policy by the council of ministers largely because of a lack of countervailing checks

migrants and housing investments theory and evidence from nigeria the dominance of housing may reflect limitations in the menu of investment choices available to migrants in the country of origin in many developing countries individuals face relatively few savings opportunities where productive assets such as land farm assets are associated with high risks and or low rates of return housing investments offer unique advantages in that they are durable highly visible and associated with low risk and monitoring requirements however there are some important drawbacks associated with housing investments in particular where resale and rental markets for housing are not well developed migrants housing assets may be relatively illiquid and irreversible in the next section i provide some background on general patterns of investment behavior among migrants here the evidence on housing investments is discussed for a rich set of migrant sending and receiving countries in section iii i develop the conceptual framework for understanding migrants housing investment decisions section iv provides a description of the data sources section v outlines the empirical strategy in section vi i discuss the empirical findings section vii presents conclusions excerpt

economic development institutional change and the political economy of agricultural protection an econometric study of belgium since the 19th century this empirical study uses 100 years of annual data on 11 agricultural commodities from belgium to measure the impact of structural changes coinciding with economic development and changes in political institutions on agricultural protection the analysis shows that changes in agricultural protection are caused by a combination of factors governments have increased protection and support to farmers when world market prices for their commodities fell and vice versa offsetting market effects on producer incomes other economic determinants were the share of the commodities in total consumer expenditures negative effect and in total output of the economy positive effect with belgium a small economy there was no impact of the trade position changes in political institutions have affected agricultural protection democratic reforms which induced a significant shift in the political balance towards agricultural interests such as the introduction of the one man one vote system led to an increase in agricultural protection the integration of belgian agricultural policies in the common agricultural policy in 1968 coincided with an increase in protection ceteris paribus both institutional factors related to changes in access to and information about the decision making at the eu level and structural changes in the agricultural and food economy may explain this effect

the crowding out effect of formal insurance on informal risk sharing an experimental study abstract this paper investigates the crowding out effect of formal insurance on informal risk sharing arrangements via theory and laboratory experiment our model and simulation predict that the crowding out of private transfers is often more than one for one and will reduce the total risk coverage furthermore the existence of a moderate degree of altruism exaggerates the crowding out effect especially when there is an ex ante income inequality these predictions are mostly supported by the laboratory experiment except that the crowding out effect is not more than one for one and hence the total risk coverage is not significantly reduced by formal insurance

the effect of women s bargaining power on child nutrition in rural senegal summary we examine how women s bargaining power affects child nutritional status using data from rural senegal in order to correct for the potential endogeneity of women s bargaining power we use information on a mother s ethnicity relative to that of the community she resides in order to construct an arguably exogenous exclusion restriction while standard ols estimates suggest that if a mother has more bargaining power her children will have a better nutritional status our iv estimates indicate that the true impact is underestimated if the endogeneity of bargaining power is not taken into account

on the economics of nonmarket transfers the role of altruism abstract we examine altruistically motivated consumption transfers in an effort to account for nonmarket transfers we find that altruistic linkages lead to autonomous negotiation free transfers and that such transfers positively respond to stronger altruism we also find that given fairly natural assumptions concerning the altruism parameters mutual altruism does not necessarily result in group social harmony even though its rise narrows the conflict range in spite of enhanced transfers prompted by such a rise both parties may end up worse off these results help explain why in some social environments a shift toward market oriented transfers and exchanges may be quicker than in others as the disadvantages decline in utility associated with intragroup altruistic linkages outweigh the advantages

do husbands and wives pool their resources evidence from the united kingdom child benefit common preference models of family behavior imply income pooling a restriction on family demand functions such that only the sum of husband s income and wife s income affects the allocation of goods and time testing the pooling hypothesis is difficult because most family income sources are not exogenous to the allocations being analyzed in this paper we present an alternative test based on a natural experiment a policy change in the united kingdom that transferred a substantial child allowance to wives in the late 1970s using family expenditure survey data we find strong evidence that a shift toward greater expenditures on women s clothing and children s clothing relative to men s clothing coincided with this income redistribution

extended families and child well being studies of household behavior have established the distribution of resources among household members predicts spending and savings patterns however there is a paucity of evidence on the relationship between the well being of individual family members and the distribution of resources within an extended family including non co resident family members given the central role the family plays in many models of economic behavior this is an important gap in the literature using rich longitudinal survey data from the indonesia family life survey ifls evidence is presented on the relationship between three measures of health and education related human capital of children and the distribution of resources among extended family members ifls is ideally suited for this research since the survey collects detailed information about income and wealth from both coresident and non co resident family members the empirical model is founded on a natural extension of the collective model of household decision making chiappori 1988 1992 to the extended family the model is particularly appealing in this context because it places few restrictions on preferences of individual family members and does not specify a specific bargaining mechanism that underlies negotiations the collective model yields empirical tests of whether the behavior of family members is pareto efficient a special case of the model allows all family members to be completely altruistic which is observationally equivalent to a unitary model of family behavior that special case is rejected by the data however the restrictions of the efficient model are not rejected indicating that non co resident family members are able to co ordinate allocation decisions with respect to child human capital investments in such a way as to make no family member better off without another member being worse off

fertilizer use risk and off farm labor markets in the semi arid tropics of india a two period model is developed in which a risk averse farmer uses off farm labor to smooth consumption leading to greater use of fertilizer fertilizer demand is shown to increase with the depth of the off farm labor market controlling for exogenous weather risk farmers use more fertilizer the lower the unemployment rate and the higher the share of nonagricultural work in total off farm labor the results suggest that off farm labor markets and own farm production may be complementary in risky production environments so that policies which promote the depth of the off farm labor market in low income areas may also bolster farm productivity copyright 2003 oxford university press

sequentially rationalizable choice a sequentially rationalizable choice function is a choice function that can be retrieved by applying sequentially to each choice problem the same xed set of asymmetric binary relations rationales to remove inferior alternatives these con cepts translate into economic language some human choice heuristics studied in psychology and explain cyclical patterns of choice observed in experiments we study some properties of sequential rationalizability and provide a full character ization of choice functions rationalizable by two and three rationales

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

wage and employment effects of malawi s fertilizer subsidy program this article uses three waves of nationally representative household level panel data from malawi to estimate how a large scale fertilizer subsidy program impacts the agricultural labor market known as ganyu in that country i find that when looking across the entire population of smallholders receiving an additional 100 kg of subsidized fertilizer causes the average household to supply about three fewer days of ganyu the fertilizer subsidy program also has a small positive effect on the probability that a household demands agricultural labor with the results approaching statistical significance in addition a 10 kg increase in the average amount of subsidized fertilizer acquired per household in a community boosts the median agricultural wage rate by 1 4 in that community the increase in wage rates translates to a us 1 40 per year increase in average household income in the years after malawi s subsidy program was scaled up and a us 1 86 per year increase in average household income for those who sold their labor before the subsidy program was scaled up this finding suggests that households who sell their labor off farm may experience some small spillover benefit from the program in the form of higher agricultural wage rates

shrouded attributes consumer myopia and information suppression in competitive markets bayesian consumers infer that hidden add on prices e g the cost of ink for a printer are likely to be high prices if consumers are bayesian firms will not shroud information in equilibrium however shrouding may occur in an economy with some myopic or unaware consumers such shrouding creates an inefficiency which firms may have an incentive to eliminate by educating their competitors customers however if add ons have close substitutes a curse of debiasing arises and firms will not be able to profitably debias consumers by unshrouding add ons in equilibrium two kinds of exploitation coexist optimizing firms exploit myopic consumers through marketing schemes that shroud high priced add ons in turn sophisticated consumers exploit these marketing schemes it is not possible to profitably drive away the business of sophisticates it is also not possible to profitably lure either myopes or sophisticates to nonexploitative firms we show that informational shrouding flourishes even in highly competitive markets even in markets with costless advertising and even when the shrouding generates allocational inefficiencies

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

testing the neoclassical model of family labor supply and fertility the mcelroy horney nash bargaining model of family demand behavior relaxes the restriction that nonearned income of husband and wife has the identical effect on family labor supply and commodity demands this restriction of the neoclassical model offamily behavior is tested for the determination of husband and wife labor supply andfertility based on the 1981 socioeconomic survey of thailand the neoclassical restriction is rejected for female labor supply andfertility another unexplored limitation offamily demand studies due to the sample self selection of intact marriages is empirically treated through alternative estimation strategies in this case a more sharply focused theory of marital behavior is needed to identify family demand models

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

income and outcomes a structural model of intrahousehold allocation there is evidence from several sources that one cannot treat many person households as a single decision maker if this is the case then factors such as the relative incomes of the household members may affect the final allocation decisions made by the household we develop a method of identifying how incomes affect outcomes given conventional family expenditure data the basic assumption we make is that household decision processes lead to efficient outcomes we apply our method to a sample of canadian couples with no children we find that the final allocations of expenditures on each partner depend significantly on their relative incomes and ages and on the level of lifetime wealth

educational homogamy how much is opportunities individuals match on length and type of education we find that around half of the systematic sorting on education is explained by the tendency of individuals to marry someone who went to the same educational institution or to an institution near them this may be due to low search frictions or selection of people with the same preferences into the same institutions the residual half of the systematic sorting on education is a direct effect of partners education which is potentially explained by complementarities in household production in couples with same education

price distortions in agriculture and their effects an international comparison the central thesis of this paper is that agricultural pricing policies pursued by developing countries produce effects which are diametrically opposite to those produced by the pricing policies of many developed countries and that the policies of both are costly in terms of global welfare in general the agricultural sector in developing countries is heavily taxed while that in the developed countries receives substantial price protection the effects of agricultural price distortions on output consumption trade and rural employment are estimated for nine countries in addition the effects of price distortions on the distribution of income between producers and consumers on government revenue and foreign exchange and the net social losses of the policies are calculated the results indicate that there are large income transfers and impacts on migration from the rural to the urban sector in developing countries and from the urban to the rural sector in developed economies

do consumers take advantage of common pricing standards an experimental investigation gaudeul and sugden gaudeul a sugden r 2012 spurious complexity and common standards in markets for consumer goods economica 79 314 209 225 have hypothesized that when some but not all competing products are priced in a common standard consumers who are liable to make errors in cross standard price comparisons use decision rules that discriminate in favor of common standard offers such behavior incentivizes sellers to use common standards we report an experimental test of this hypothesis using choice tasks similar to those represented in the gaudeul sugden model we find that offers priced in common standards were more likely to be inspected but less likely to be chosen and that subjects gained little benefit from common pricing standards that applied to some but not all offers most subjects used dominance editing operations that eliminated transparently dominated offers either as an initial shortlisting device or while offers were being sorted because these operations discriminate against

remittances and household wealth after conflict a case study on urban burundi few studies have researched the use of remittances in conflict affected contexts this study analyzes unique data from burundi testing three hypotheses relative deprivation investment and insurance derived from new economics of labor migration studies employing propensity score matching results show that remittances are common among wealthier households rejecting the relative deprivation hypothesis remittances have strong effects on non productive assets such as living conditions and food security and weak effects on productive assets such as asset ownership poorer households invest mostly in non productive assets suggesting that remittances are insurance for the poor whereas wealthier households seem largely unaffected by remittances

precautionary behavior migrant networks and household consumption decisions an empirical analysis using household panel data from rural china abstract we develop a test of precautionary behavior in the consumption decisions of rural agricultural households among surveyed households facing a median level of consumption risk 10 of savings can be attributed to a precautionary motive and this increases to 15 for households with consumption per capita below the poverty line we next use distant lags of local rainfall shocks uncorrelated with current consumption growth to identify the size of migrant networks outside the village and then present evidence that both poor and nonpoor households engage in less precautionary saving as the size of the village migrant network increases

who gets the job referral evidence from a social networks experiment we use recruitment into a laboratory experiment in kolkata india to analyze how job networks select individuals for employment opportunities we present evidence that individuals face a tradeoff between choosing the most qualified individual for the job and the individual who is ideal from the perspective of their social network the experiment allows randomly selected subjects to refer members of their social networks to subsequent rounds of the experiment and varies the incentive schemes offered to these participants we find that when faced with performance pay individuals are more likely to refer co workers and less likely to refer family members high ability participants who are offered performance pay recruit referrals who perform significantly better on a cognitive ability task and also prove to be more reliable as evidenced by their choices in the trust game and performance on an effort task

bargaining and distribution in marriage the standard economic model of the family is a common preference model that assumes that a family maximizes a single utility function and implies that family behavior is independent of which individuals receive income or control resources in recent years this model has been challenged by game theoretic models of marriage that do not impose pooling and are therefore consistent with empirical evidence that income controlled by husbands and wives does have different effects on family behavior in this paper the authors review a number of simple bargaining models and relevant empirical evidence and discuss their implications for distribution within marriage

periodic high risk as a cause of fertility decline in a changing rural environment survival strategies in the 1980 1983 south indian drought in the attempt to explain persistent high fertility in much of the third world attention has been drawn both to current returns from child labor and to the mitigation or avoidance of future risks the latter can be subdivided into meeting emergencies while the parental generation is still of working age and providing for old age or even safeguarding the transmission of family property on parental death the problems of old age have recently received most attention and they may well be of paramount importance in many societies yet in a research program that we have conducted in rural south india since 1979 the reasons given for demographic behavior have more frequently emphasized the need to plan strategies to meet periodic crisis than to ensure old age support 2 nevertheless one should not underemphasize the latter merely because the problem is predictable and the solutions understood in the study area for the great majority of the aged the support system still worked well 3 in contrast in our investigations of marriage fertility control and education we repeatedly discovered that a fundamental consideration with regard to parental decisions in these areas was to strengthen the ability of the family to withstand periodic crises 4 by far the most important type of crisis in this dry drought prone area was recurrent famines resulting

motivations to remit evidence from botswana in this article a theory of motivations to send remittances is described and tested with data from botswana altruism is one of the motivations tested and found to be an insufficient explanation for remittances among migrants in botswana a refinement of the model stipulates a modified altruism or enlightened self interest in this model the relationship between the migrant and family is tempered by an implicit understanding of mutual benefit the household strategy may be to encourage some members to migrate as a means of spreading risk and sharing gains the household strategy is similar to an insurance policy where migration is to places where market potential is high the risks incurred might be high the example is given of migration during a drought in botswana migrant remittances were greater in households with more cattle or households with more to lose drought alone was not statistically related to remittances increases in remittances were related to increased levels of education it is suggested that repayment was the motive for parents investment in migrants education migrants gains are identified as the potential for an inheritance the security of channeling investments through a trusted family member and security in having a home to return to it is pointed out that the altruism and family remittances from urban migration were strategies that bridged the simple dynamic of either urban development or rural development impacting on family welfare it is suggested that household models of economy adopt some measure to express the relationship of household wealth to remittances from urban migrants

adding asymmetrically dominated alternatives violations of regularity and the similarity hypothesis an asymmetrically dominated alternative is dominated by one item in the set but not by another adding such an alternative to a choice set can increase the probability of choosing the item that dominates it this result points to the inadequacy of many current choice models and suggests product line strategies that might not otherwise be intuitively plausible

determinants and effects of income diversification amongst farm households in burkina faso using four years of household data from three agroecological zones in burkina faso sahelian sudanian and guinean the article examines the determinants and effects of household income diversification harvest shortfalls and terms of trade are found to drive diversification but land constraints do not income diversification is associated with higher incomes and food consumption and more stable income and consumption over years

women and structural transformation development is at a relatively early stage 2 analysis of women s role as economic actors as distinct from being part of the labor force in general is still rudimentary 3 the extent to which and the conditions under which gender may influence a variety of economic outcomes are not well researched the nature and the extent of segmentation of economic activity between males and females and their changing roles in different socioeconomic settings and during the course of economic development are inadequately investigated in economic literature 4 consequently whether the efficiency and welfare losses from women s low participation in economic activity are significant in static and dynamic contexts is inadequately articulated much of the research on women in developed countries has been in a comparative static context 5 the changes in incomes technology demography and tastes with regard to women s roles however are not only much more rapid but also simultaneous in developing countries making research in a comparative static context of relatively little value the implications of the dynamic factors are analytically complex to handle but are critical for public policy even where policy implications are obvious from the existing limited research however these have not always been effectively incorporated by governments in their actions this article first summarizes the major themes of the various types

explaining price policy bias in agriculture the calculus of support maximizing politicians a model is developed to explain observed patterns of policy intervention in agriculture we analyze the interaction between political support seeking politicians and supportsupplying citizens society consists of a rural and urban group we determine the effects on transfers of relative group size disparities in income endowments between groups and the deadweight loss of redistribution the framework advanced is an alternative to that of the interest group model and is used to explain for example why the export sectors in developing countries are taxed more and why the united kingdom is less adamant for higher price supports than germany

migration and economic mobility in tanzania evidence from a tracking survey this study explores the extent to which migration has contributed to improved living standards of individuals in tanzania using longitudinal data on individuals the authors estimate the impact of migration on consumption growth between 1991 and 2004 the analysis addresses concerns about heterogeneity and unobservable factors correlated with both income changes and the decision to migrate the findings show that migration adds 36 percentage points to consumption growth during a period of considerable growth in consumption these results are robust to numerous tests and alternative specifications unpacking the findings the analysis finds that moving out of agriculture is correlated with much higher growth than staying in agriculture although growth is always higher in any sector if one physically moves economic mobility is strongly linked to geographic mobility the puzzle is why more people do not move if returns to geographic mobility are high the evidence is consistent with models in which exit barriers are set by home communities through social and family norms that prevent migration of certain categories of people

networks in economic development this chapter surveys the implications of some studies in network economics research for economic development we focus on information flow and risk sharing two topics where work in theory empirics and policy analysis have been especially intensive and complementary in analysing information we distinguish models of information diffusion and aggregation highlight how different models imply very different guidance regarding the right way to seed information in discussing risk sharing we look at the key frictions that impede efficient informal insurance and some potential unintended consequences when policymakers intervene to help throughout we stress practical insights that can be used with limited measurement of the details of networks

the economics of polygyny in sub saharan africa female productivity and the demand for wives in cote d ivoire polygyny is still practiced throughout much of sub saharan africa with important social consequences this paper makes the first attempt to link african polygyny directly to the productivity of women in agriculture using micro data i develop a structural model of the demand for wives that disentangles wealth and substitution effects using a large household survey from cote d ivoire i find that marked geographic diversity in cropping patterns leads to regional variation in female labor productivity i also find that conditional on wealth men do have more wives when women are more productive that is cheaper this substitution effect may explain why polygyny declined in rural areas of cote d ivoire during agricultural development

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

a two season agricultural household model of output and price uncertainty abstract this paper presents a two season model of a household s production consumption labor supply and storage decisions in an environment of output and price risk the analytical results in this study are markedly different from those of models prevalent in the mainstream of the agricultural household literature the empirical analysis that uses panel data from a village in india provides support for the theoretical results and underscores the seasonal dimension of the farmers choice problems the results also show that ignoring risk or risk averse preferences may introduce substantial downward bias in optimal response estimates

consumption smoothing migration and marriage evidence from rural india a significant proportion of migration in low income countries particularly in rural areas is composed of moves by women for the purpose of marriage we seek to explain these mobility patterns by examining marital arrangements among indian households in particular we hypothesize that the marriage of daughters to locationally distant dispersed yet kinship related households is a manifestation of implicit interhousehold contractual arrangements aimed at mitigating income risks and facilitating consumption smoothing in an environment characterized by information costs and spatially covariant risks analysis of longitudinal south indian village data lends support to the hypothesis marriage cum migration contributes significantly to a reduction in the variability of household food consumption farm households afflicted with more variable profits tend to engage in longer distance marriage cum migration the hypothesized and observed marriage cum migration patterns are in dissonance with standard models of marriage or migration that are concerned primarily with search costs and static income gains

an exogeneity test for a simultaneous equation tobit model with an application to labor supply a test of weak exogeneity in the simultaneous equation tobit model is proposed and illustrated using a female labour supply model estimated using cross section data the test statistic can be simply output from any standard tobit maximum likelihood package and is asymptotically efficient the procedure provides consistent estimators for the simultaneous tobit model whose asymptotic covariance matrix is a simple extension of the usual tobit formula we also provide the lagrange multiplier test of weak exogeneity this abstract was borrowed from another version of this item

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

methods of household consumption measurement through surveys experimental results from tanzania consumption expenditure has long been the preferred measure of household living standards however accurate measurement is a challenge and household expenditure surveys vary widely across many dimensions including the level of reporting the length of the reference period and the degree of commodity detail these variations occur both across countries and also over time within countries there is little current understanding of the implications of such changes for spatially and temporally consistent measurement of household consumption and poverty a field experiment in tanzania tests eight alternative methods to measure household consumption on a sample of 4 000 households there are significant differences between consumption reported by the benchmark personal diary and other diary and recall formats under reporting is particularly relevant in illiterate households and for urban respondents completing household diaries recall modules measure lower consumption than a personal diary with larger gaps among poorer households and households with more adult members variations in reporting accuracy by household characteristics are also discussed and differences in measured poverty as a result of survey design are explored the study concludes with recommendations for methods of survey based consumption measurement in low income countries

the dual policy in the dual economy the political economy of urban bias in dictatorial regimes in many developing countries public resource allocation is often biased against the rural population since a vast majority of the poor live in rural areas the bias is highlighted as one of the most important institutional factors contributing to poverty this paper develops a political economy model of urban bias in a dictatorial regime a novel result of the model is that urban bias can emerge in predominantly agrarian economies even if there is no bias in political power toward urban residents the empirical evidence from a recently compiled country level panel dataset on agricultural taxes subsidies is consistent with the prediction of the model

consumption smoothing and the welfare consequences of social insurance in developing economies studies of risk in developing economies have focused on consumption fluctuations as a measure of the value of insurance a common view in the literature is that the welfare costs of risk and benefits of social insurance are small if income shocks do not cause large consumption fluctuations we present a simple model showing that this conclusion is incorrect if the consumption path is smooth because individuals are highly risk averse hence social safety nets could be valuable in low income economies even when consumption is not very sensitive to shocks

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

parental human capital investment and old age transfers from children is it a loan contract or reciprocity for indonesian families abstract this paper proposes two alternative models of intergenerational transfers linking parental investment in human capital of children to old age support the first model formulates these transfers as a pure loan contract and the second model as self enforcing reciprocity both models predict neutrality of intergenerational redistribution of resources within the family also known as the difference in income transfer derivatives property two models however provide different reasons for the failure of this property and yield different policy implications for parental human capital investment and provision of old age support specification tests on the indonesian family life survey data reject the pure loan model in favor of the reciprocity model the estimated difference in income transfer derivatives for this data is found to be significantly higher than the difference estimated by altonji hayashi and kotlikoff altonji et al 1992 altonji j g hayashi f and kotlikoff l j 1992 is the extended family altruistically linked direct tests using micro data the american economic review vol 82 5 1177 98 for the u s psid data

vulnerability of victims of civil conflicts empirical evidence for the displaced population in colombia summary internal conflicts and the forced displacement often caused by such conflicts impose a heavy burden on the civilian population and greatly damage a community s overall welfare the present study employs a household level survey administered to 2 322 colombian displaced households to estimate changes in household welfare after displacement and to assess aggregate consumption levels in destination sites we also assess whether households are able to smooth consumption and we analyze the strategies they are compelled to adopt in order to cope our results indicate that victims of civil conflict face difficulties in generating income are unable to rely on usual risk sharing mechanisms and are forced to draw upon costly coping strategies in order to smooth consumption the vulnerability of displaced households and the possibility of falling into poverty traps highlight the need to design and implement specific policies for victims of internal conflict in order to cope with the displacement shock

winners and losers among a refugee hosting population abstractthe impact of a sudden mass influx of forced migrants on the hosting economy is understudied and not well understood using a household panel data set for the kagera region in tanzania we test the impact of the mass refugee presence on the welfare of the local population our identification strategy exploits variations in the timing of arrival as well as the spatial distribution of rwandese and burundi refugees we find a positive and aggregate effect but households are affected differently depending on their main initial occupation

testing efficient risk sharing with heterogeneous risk preferences previous papers have tested e cient risk sharing under the assumption of identical risk preferences in this paper we show that if in the data households have heterogeneous risk preferences the tests proposed in the past reject e ciency even if households share risk e ciently to address this issue we propose a method that enables one to test e ciency even when households have difierent preferences for risk the method is composed of three tests the flrst one can be used to determine whether in the data under investigation households have homogeneous risk preferences the second and third test can be used to evaluate e cient risk sharing when the hypothesis of homogeneous risk preferences is rejected we use this method to test e cient risk sharing in rural india using the flrst test we strongly reject the hypothesis of identical risk preferences we then test e ciency with and without the assumption of preference homogeneity in the flrst case we reject e cient risk sharing at the village and caste level in the second case we still reject e ciency at the village level but we cannot reject this hypothesis at the caste level this flnding suggests that the relevant risk sharing unit in rural india is the caste and not the village

income smoothing and consumption smoothing one way that risk averse households protect consumption levels is to borrow and use insurance mechanisms another way common in low income economies is to diversify economic activities and make conservative production and employment choices households thus tend toward limiting exposure only to shocks that can be handled with available credit and insurance typically both types of mechanisms are studied independently but much more can be learned by studying them together first we obtain a more complete picture of risks costs and insurance possibilities second it opens the way to considering biases in standard tests of credit and insurance

what does japanese trade structure tell us about japanese trade policy some argue foreign access to japanese markets remains tightly controlled and that if japan is to be a member in good standing of the international economic system japan must do more than just adhere to the formal rules of the gatt japan must show by the results of its international economic transactions that foreign access to its market is not tightly controlled as this point of view is increasingly dominating american economic diplomacy with japan it is particularly important that its premise be examined first i examine japan s growth record and trade record to the extent that japan s trade performance is different i explore whether the difference can legitimately be attributed to japanese policies this paper finds that neither the price behavior of japanese firms nor the pattern and volume of what japan imports or exports suggests that japan s trade regime is different some of japan s economic institutions may be distinctive but there is little evidence they produce outcomes which distort the international economic system what remains to be explained is the conviction of so many that japan is more a parasite than a pillar of the international economic system the record of economic research directly and indirectly bearing on this issue does not support such a conclusion at all

improving identification of demand side obstacles to schooling findings from revealed and stated preference models in two ssa countries summary efforts to expand primary education have shifted from a policy focus on supply building schools to demand side policies human capital theory posits that common demand side obstacles are high direct costs opportunity costs and low perceived benefits constructs that are difficult to measure empirically this study compares strategies to estimate obstacles to schooling through revealed and stated preferences using similar household survey data from two sub saharan african countries the typical determinants of schooling model underestimates demand side obstacles and gender differences and additional useful information for theory testing and policy is derived from analyzing parents stated preferences as well

migration risk and liquidity constraints in el salvador abstract this article utilizes panel data from el salvador to investigate the use of transnational migration as an ex post risk management strategy i show that adverse agricultural conditions in el salvador increase both migration to the united states and remittances sent back to el salvador i show that in the absence of any agricultural shocks the probability that a household sent members to the united states would have decreased on average by 24 26 i also show that the 2001 earthquakes reduced net migration to the united states a one standard deviation increase in earthquake damage reduced the average probability of northward migration by 37 11 the evidence suggests that the effects of the earthquakes had more to do with households retaining labor at home to cope with the effects of the disaster than with the earthquakes disrupting migration financing

will you marry me a perspective on the gender gap abstract this paper develops a general equilibrium model of the gender wage gap the difference in earnings is a consequence of a demographic regularity that men tend to marry younger women which may limit women s labor mobility and hence their average earnings however couples are always free not to marry and do so only if it is in each s self interest the intrafamily allocation of resources is determined via non cooperative bargaining this leads to interesting interactions between the game played by husband and wife on the one hand and the competitive environment in which they are immersed on the other the predictions resulting from this model s interplay between locational choice and family bargaining are consistent with the observation that the increasing stress put by women on their careers over the past 30 years has been contemporaneous with reductions in both marriage rates and the gender gap the model provides insight into the consequences of this for the relative welfare of men and women as well as exploring its wider economic implications

women s empowerment and wellbeing evidence from africa abstractwe use household survey data from senegal to model the effects of empowerment within the home on married women s wellbeing the estimated effects of empowerment are at least as large as more conventional development indicators such as household income the size of the empowerment effect is robust to alternative estimation techniques including an instrumental variables estimator

structure of agricultural protection in industrial countries abstract the nominal rates of agricultural protection in ten industrial countries from 1955 to 1980 are estimated with the same commodity coverage and data definitions a regression analysis is conducted to explain variations in the measured level of agricultural protection in terms of political as well as economic factors nearly 80 percent of the variations is accounted for by differences in agriculture s comparative advantage agriculture s share in total economy the international terms of trade between agricultural and manufactured commodities regionalism eec and food security consideration associated with non military alliance

overconfidence and excess entry an experimental approach psychological studies show that most people are overconfident about their own relative abilities and unreasonably optimistic about their futures e g shelly e taylor and j d brown 1988 neil d weinstein 1980 when assessing their position in a distribution of peers on almost any positive trait like driving ability ola svenson 1981 income prospects or longevity a vast majority of people say they are above the average although of course only half can be if the trait is symmetrically distributed this paper explores whether optimistic biases could plausibly and predictably influence economic behavior in one particular setting entry into competitive games or markets many empirical studies show that most new businesses fail within a few years for example using plant level data from the u s census of manufacturers spanning 1963 1982 timothy dunne et al 1988 estimated that 61 5 percent of all entrants exited within five years and 79 6 percent exited within 10 years most of these exits are failures see also dunne et al 1989a 1989b d shapiro and r s khemani 1987

agricultural policy adjustments in the korean rice economy abstract a political preference function is used to endogenize government actions in a simultaneous equation model for south korean rice policy the effects of economic changes on rice pricing decisions through estimated political weights are tested to improve our understanding of policy adjustments in that country and open the way for further research in east asia

the economics of consanguineous marriages the institution of consanguineous marriage a marriage contracted between close biological relatives has been a basic building block of many societies in different parts of the world this paper argues that the practice of consanguinity is closely related to the practice of dowry and that both arise in response to an agency problem between the families of a bride and a groom when marriage contracts are incomplete dowries transfer control rights to the party with the highest incentives to invest in a marriage when these transactions are costly however consanguinity can be a more appropriate response since it directly reduces the agency cost the paper s model predicts that dowry transfers are less likely to be observed in consanguineous unions it also emphasizes the effect of credit constraints on the relative prevalence of dowry payment and consanguinity an empirical analysis using data from bangladesh delivers robust results consistent with the predictions of the model

imperfect commitment altruism and the family evidence from transfer behavior in low income rural areas in this paper we examine empirically whether risk pooling is more advantageous among altruistic compared to selfish agents in a framework where individuals cannot make binding commitments in particular we incorporate altuism into a model of risk sharing under imperfect commitment and use simulation methods to establish tests of the roles of both altruism and commitment problems in determining the extent of insurance and the intertemporal movements in interhousehold transfers the tests are carried out using three panel data sets from two countries of rural south asia that provide detailed information on transfers and enable the measurement of income shocks the estimates provide strong support for the notion that imperfect commitment substantially constrains informal transfer arrangements whether kin based or not but also provide evidence that altruism plays an important role in ameliorating commitment constraints and thus in increasing the gains from income pooling

diaspora growth and aggregate remittances an inverted u relationship this paper presents a model in which remittances stem from a decision made jointly by a family coalition of multiple migrants and non migrants allowing two alternative interpretations migrants a

growth of agricultural protection in east asia abstract japan is well known for its restrictions on food imports less well known is the fact that south korea and taiwan are also protective of their agricultural sectors this protectionism began early this century when all three countries were part of the japanese empire and it has increased rapidly during the 1960s and 1970s today food prices in east asia average two or three times higher than in international markets reflecting levels of protection that rival those in western europe

storm damage and risk preferences panel evidence from germany individuals risk preferences may change after experiencing external socio economic or natural shocks theoretical predictions and empirical studies suggest that risk taking may increase or decrease after experiencing shocks so far the empirical evidence is sparse especially when it comes to developed countries we contribute to this literature by investigating whether experiencing financial and health related damage caused by storms affects risk preferences of individuals in germany using unique panel data we find that household heads were more risk seeking after they experienced storm damage we do not find evidence of exposure to storm per se regardless of damage experience which suggests that household heads have to suffer damage for their risk preferences to be affected these results are robust across a battery of alternative model specifications and alternative storm damage measures magnitude of financial damage we rule out other potential explanations such as health related and economic shocks the self reported storm damage data is broadly confirmed by regional storm damage data provided by the insurance industry while we cannot identify the channels through which experiencing storm damage affects risk preferences from our data we suggest and discuss some potential channels the results may have important policy implications as risk preferences affect for instance individuals savings and investment behaviour adoption of self protection and self insurance strategies and technology adoption

assortative matching and risk sharing abstract this paper explores the sorting patterns in a two sided matching market where agents facing different risks match to share them when preference belongs to the class of harmonic absolute risk aversion hara the risk premium is perfectly transferable within each partnership thus a stable match minimizes the social cost of risk in the systematic risk model where agents are ranked by their holdings of a common risky asset the convexity of the joint risk premium in joint risk size leads to negative assortative matching nam in the idiosyncratic risk model where agents are ranked by their independent riskiness in the sense of second order stochastic dominance ssd nam arises when preference exhibits decreasing absolute risk aversion dara in the sense of ross and riskier background risk leads to more risk averse behavior however nam may fail to arise when riskier background risk leads to more risk tolerant behavior

no toilet no bride intrahousehold bargaining in male skewed marriage markets in india abstract haryana state in india is characterized by widespread discrimination against women including a severe population level sex imbalance in this context an innovative social marketing campaign which targeted pro sanitation messages to households active in local marriage markets was implemented with the goal of increasing toilet ownership this paper estimates the impact of this program known colloquially as no toilet no bride on household level latrine ownership private sanitation coverage in haryana increased by 21 specifically among households with boys active on the marriage market this effect is larger and concentrated in marriage markets where women are relatively scarce and absent when women are relatively abundant which together suggest the program operated by successfully linking sanitation outcomes with marriage market competition induced by local scarcities of women due to male biased sex ratios

protectionary bias in agriculture a pure economic argument abstract empirical evidence suggests that the agricultural sector in the developed countries has enjoyed a greater degree of protection than the import competing manufacturing sectors usually this is attributed to strong farm lobbies and hence on political factors we provide a theoretical model and a possible explanation of this phenomenon based on purely economic arguments two importables are accommodated in a three good three factor model of trade and production one is a labor intensive manufacturing good and the other is an agricultural commodity this captures the trade pattern of a typical industrialized country with an agricultural sector such as europe and the usa we show that uniform tariffs in agriculture and labor intensive manufacturing will definitely hurt the land owners in real terms and may reduce their absolute return hence if there has to be protection it has to be biased in favor of agriculture

what drives china s new agricultural subsidies summary china s agricultural policy has undergone a fundamental transformation in the four decades since the introduction of market reforms in 1978 and now involves a wide array of policy instruments that range from output and input subsidies to public infrastructure expenditures this article analyzes the political economic determinants of china s agricultural subsidy changes using producer subsidy equivalents pses drawn from annual data from 1984 to 2015 on 16 agricultural commodity sectors that include multiple policy instruments empirical results indicate that national factors such as high rates of economic growth and a lower share of agriculture in the economy have been the primary drivers of increases in pses and that larger more geographically concentrated agricultural sectors are more likely to be subsidized at a higher pse rate finally china s joining the world trade organization in december 2001 led to significant increases in pses that were not already explained by internal national or commodity specific factors in essence china s agricultural subsidy programs and levels increasingly resemble those of developed countries primarily as a result of economic transformation and the ability to structure agricultural policies within the wto rules moreover this article predicts that agricultural subsidies will trend slightly upward in the next decade and that the strongest opportunities to export to china will be in animal products or grains that are utilized for feed or processed foods where the levels of subsidies are predicted to increase but remain lower than for traditional food crops

do private transfers displace the benefits of public transfers evidence from south africa abstract this paper investigates whether government transfer programs displace or crowd out private support focusing on a large increase in state old age pensions in south africa using data spanning the period of the expansion we find that each rand of public pension income to the elderly leads to a 0 25 0 30 rand reduction in private transfers from children living away from home however despite the large increase in income there were no significant changes in migration labor supply or household composition we also show that evaluations of the distributional effects of the pension are overstated when crowding out is ignored

risk sharing across communities this paper studies cross community risk sharing there is now a large body of theoretical and empirical work on informal insurance where people mitigate risk by sharing income a consistent empirical finding is that risk sharing is not complete within villages often the observed sets of individuals 2 one reason researchers suspect is that risk sharing does not take place at the village level but between individuals and families 3 we build a theoretical model where risksharing takes place between pairs of agents there are idiosyncratic shocks to individual income and community level shocks we consider how the opportunity for cross community links affects the shape and efficiency of risk sharing arrangements we find that when links across villages form there can be less risk sharing within a village welfare is higher for those directly or indirectly connected across villages but lower for those with no path connecting them to the other village overall welfare can be higher thus empirical findings that insurance within a village is not complete is not necessarily evidence of an inefficient pattern of risk sharing relations rather the finding is consistent with risk sharing patterns that involve cross community relations and such patterns may yield higher aggregate welfare despite incomplete insurance within a village this paper makes two contributions first it demonstrates the importance of a network analysis by examining pairwise incentives to form relations and the resulting pattern we can see new risk sharing outcomes second with this network model we show how informal risk sharing across communities has both aggregate and distributional effects to study network outcomes we posit a simple two stage model first we provide a benchmark model for risk sharing for a given network then working backwards we consider incentives to form risk sharing links 4 to illustrate consider a rural population and ask how people might link

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

credit constraints job mobility and entrepreneurship evidence from a property reform in china this paper provides new evidence on the impact of private property rights on entrepreneurship i explore this issue in the context of a housing reform in urban china that allowed state employees renting state owned housing the opportunity to buy their homes at subsidized prices using the reform as an exogenous change in the capital constraints and mobility costs that inuence individuals entry

remittances and portfolio values an inquiry using immigrants from africa europe and the americas summary using a recent spanish database we show that remittances respond to cross country differences in portfolio values behavior consistent with immigrant s access to trans national networks responsiveness to portfolio variables is found to persist regardless of education level there are however differences in the portfolio variables to which immigrants respond as we would expect given migrants diverse backgrounds region of origin and motive for emigrating remitting patterns are found to change with the length of migration spells suggestive that remittances sent for portfolio motives become more likely as the immediate needs of home family are addressed and asset accumulation becomes more important

consideration sets and competitive marketing we present a model of competitive marketing based on the notion that consumers are boundedly rational and that firms use marketing tactics in an attempt to influence consumers decision process the standard model of consumer behaviour assumes that the consumer applies well defined preferences to a perfectly perceived set of available alternatives we retain the assumption that consumers have stable preferences but relax the assumption that they have a perfect perception of what is relevant for their consumption problem thus allowing firms to manipulate that perception our aim is to explore the market implications of this departure from the standard model especially for the way firms deploy marketing strategies in competitive environments the cornerstone of our model is the observation that in the modern marketplace consumers face an overwhelmingly large variety of products and therefore often use screening criteria deliberate as well as unconscious in order to reduce the number of relevant alternatives as a result consumers apply their preferences not to the set of objectively feasible alternatives but to a potentially smaller set which they construct at an earlier stage of the decision process borrowing a term from the marketing literature we refer to this set as the consideration set the basic idea underlying this term is that consumers may be unaware of some of the feasible products and even when they become aware of a new product they still need to be persuaded to consider it as a potential substitute to their currently consumed product

the economics of exogamous marriage in small scale societies marriage is a core institution in almost every human society including small scale societies based on foraging or subsistence agriculture a crucial dimension of the marriage systems in such societies involves endogamy and exogamy that is the choice of a marriage partner from within one s own community or from an outside community we develop a model in which the exogamy rate is higher when good local matches are scarce due to small community sizes and when productivity differs across communities due to environmental shocks these theoretical predictions are supported by econometric analysis of data from the standard cross cultural sample jel d13 j11 n30 z13

female migration for marriage implications from the land reform in rural tanzania summary using the longitudinal household panel data drawn from rural tanzania 1991 2004 this study investigates impacts of the land reform on women s marriage motivated relocation during the period under study several villages that initially banned a widow s land inheritance abolished this discrimination taking a differences in differences approach this study finds that the probability of males marrying in a village increased by altering its customary land inheritance rule in favor of widows in the light of the traditional system favoring exogamous and patrilocal marriage this finding indicates that females relocate at marriage in response to the favorable land tenure system at the destination

spurious complexity and common standards in markets for consumer goods behavioural and industrial economists have argued that because of cognitive limitations consumers are liable to make sub optimal choices in complex decision problems firms can exploit these limitations by introducing spurious complexity into tariff structures weakening price competition this paper models a countervailing force consumers choice problems are simplified if competing firms follow common conventions about tariff structures because such a common standard promotes price competition a firm s use of it signals that its products offer value for money if consumers recognize this effect there can be a stable equilibrium in which firms use common standards and set competitive prices

moving forward looking back the impact of migration and remittances on assets consumption and credit constraints in the rural philippines abstract this paper investigates the impact of migration and remittances on asset holdings consumption expenditures and credit constraint status of households in origin communities using a unique longitudinal data set from bukidnon philippines taking into account the endogeneity of the number of migrants and remittances received a larger number of migrant children reduces the values of nonland assets and total expenditures per adult equivalent however remittances have a positive impact on housing consumer durables nonland assets total expenditures per adult equivalent and educational expenditures enabling asset accumulation and investment in human capital neither migration nor remittances affects current credit constraint status
