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

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

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

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

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

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

the political economy of trade liberalization and environmental policy a pressure group model where environmental and industry lobby groups offer political support in return for favorable pollution tax policies is used to explain and predict the equilibrium pollution tax in sectors protected by tariffs the political economy effects of trade liberalization are investigated the pollution tax is shown to decrease if the lobbying effort by the environmental lobby decreases more rapidly than by the industry lobby ceteris paribus the level of political conflict falls with trade liberalization pollution may increase because of a reduction of the pollution tax and tax revenues may fall simultaneously as pollution increases the global trading system is currently undergoing another round of multilateral trade liberalization and regional economic integration is occurring in several parts of the world the trade environment link has become an important part of trade liberalization talks it is commonplace for industry representatives to argue that less stringent environmental regulations give less developed countries ldcs a comparative advantage in pollution intensive goods and that industries with high abatement costs will migrate to ldcs environmentalists argue that international differences in environmental laws and regulations may be reduced to their lowest common denominator through political pressure this is not a fear of trade liberalization itself but of the effects of lower trade barriers on the political determination of environmental regulation

off farm labor market decisions and agricultural shocks among rural households in kenya using household level data from rural kenya this article explores whether and how farm households respond to unfavorable agricultural production environments including any ex post adjustments in off farm labor supply in response to unexpected weather shocks while controlling for a wide range of educational demographic and other locational factors we examine how long term weather conditions and specific rainfall shocks influence a household s decision to engage in and their earnings from the off farm labor market we find that rural households engage in off farm work as a long term strategy to deal with the effects of anticipated weather conditions on their farming operations the analysis does not reveal major short term adjustments in off farm engagement as a result of specific unexpected rainfall shocks these households do however rely on remittance income and petty agricultural wage labor under these circumstances holding other factors constant and conditional on participation households in areas with a more productive local agriculture tend to earn more from off farm work especially in the informal business sector than their counterparts in regions with a less productive agriculture as expected a vibrant local economy in the form of public investment increases the probability of off farm participation

the political economy linkage between trade liberalization and domestic environmental regulations this paper considers the political economy linkage between trade liberalization and domestic environmental regulations in a duopolistic product market we investigate the environmental consequences and welfare implications of a home country s unilateral tariff reduction on a polluting good in a framework where the domestic environmental tax is subject to the influence of the home firm we find that a tariff reduction on a good producing a consumption type externality will improve the home country s environmental quality moreover we find that the home country s tariff reduction will unambiguously enhance the home country s welfare and it will damage the foreign firm s profits and thus the foreign country s welfare provided that the weight that the home government attaches to its social welfare is sufficiently small this result also suggests the possibility that a unilateral tariff reduction will achieve a pareto improvement

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

the effect of household wealth on fertiliser use in the presence of uncertainty abstractprevious studies of wealth effect on fertiliser use have produced mixed results on the direction of the impact our article looks at this issue from a different perspective by considering the presence of doubts such as about the true content or general effectiveness of fertiliser we show theoretically that there could be different responses between the high wealth and low wealth farmers we analyse also the wealth effect empirically using household panel data from the hebei province of china the results indicate that the direction of wealth effect does indeed change across the different levels of farmers wealth

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

nutrition information and household behavior experimental evidence from malawi incorrect knowledge of the health production function may lead to inefficient household choices and thereby to the production of suboptimal levels of health this paper studies the effects of a randomized intervention in rural malawi that over a six month period provided mothers of young infants with information on child nutrition without supplying any monetary or in kind resources a simple model first investigates theoretically how nutrition and other household choices including labor supply may change in response to the improved nutrition knowledge observed in the intervention areas we then show empirically that the intervention improved child nutrition household food consumption and consequently health we find evidence that labor supply increased which might have contributed to partially fund the increase in food consumption this paper is the first to study whether non health choices particularly parental labor supply might be affected by parents knowledge of the child health production function

international trade and environmental quality a survey abstract international trade has been incorporating various aspects of environmental issues since 1970 the extent to which environmental problems might affect many facets of trade or vice versa has been the subject of considerable debate over these years in this article we have attempted to establish some of the links between international trade and environmental quality by performing a comprehensive literature review we discuss issues such as establishing direct and indirect effects of international trade on environmental quality effects of trade on economic development environmental quality and energy and their relation with each other and finally the role of governments and international organizations in this context studies have so far revealed some linkages between trade and environment through conventional trade theory however interactions between international trade and types of pollution their sink and assimilative capacity need to be analyzed using a general equilibrium approach currently very little knowledge and agreement on the nature of interactions between trade theories development process and environmental quality exist existing studies have shown that the structure of environmental regulations should be modified to reflect the existence of trade under imperfect competition therefore further research on the interaction between new trade theory and environmental regulation is needed also theoretical and quantitative analysis regarding the effects of environmental regulations on competitiveness and location decision is needed the intensity and type of environmental measures vary across issues and countries therefore harmonizing environmental measures creates an inefficient atmosphere and to assume that trade restrictions will either improve or reverse the environmental damages is a serious mistake given the dynamic and intricate nature of the problem trade and environment debate continues despite vast research and poses a challenge for researchers and policy makers in the foreseeable future

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

annual redistribution and lifetime redistribution abstract i propose a method to evaluate the degree of income redistribution throughout a person s life time an international comparison of life time redistribution in the united states the united kingdom and japan has been attempted this comparison clearly shows the differences in the degree of redistribution in each of the countries

channels of interstate risk sharing united states 1963 1990 we develop a framework for quantifying the amount of risk sharing among states in the united states and construct data that allow us to decompose the cross sectional variance in gross state product into several components which we refer to as levels of smoothing we find that 39 percent of shocks to gross state product are smoothed by capital markets 13 percent are smoothed by the federal government and 23 percent are smoothed by credit markets the remaining 25 percent are not smoothed we also decompose the federal government smoothing into subcategories taxes transfers and grants to states

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

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

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

how does risk management influence production decisions evidence from a field experiment weather is a key source of income risk especially in emerging market economies this paper uses a randomized controlled trial involving indian farmers to study how an innovative rainfall insurance product affects production decisions the authors find that insurance provision induces farmers to invest more in higher return but rainfall sensitive cash crops particularly among educated farmers this shift in behavior occurs ex ante when realized monsoon rainfall is still uncertain the results suggest that financial innovation can mitigate the real effects of uninsured production risk

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

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

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

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

credit market constraints consumption smoothing and the accumulation of durable production assets in low income countries investments in bullocks in india in this paper we formulate and estimate a finite horizon structural dynamic model of agricultural investment behavior that incorporates the major features of low income agricultural environments income uncertainty constraints on borrowing and rental markets and the use of investment assets to generate income and smooth consumption the model is fit to longitudinal indian household data on farm profits bullock stocks and pump sets the estimated structural parameters are used to assess the effects on the life cycle accumulation of bullocks agricultural profits and welfare associated with complete markets and bullock liquidity and with second best policies that provide assured sources of income to farmers and weather insurance

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

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

ex ante and ex post labor supply response to risk in a low income area abstract this paper tests for ex ante and ex post labor supply responses to weather risk for rural indian farm households the analysis uses panel data on 2115 households spanning 13 states in rural india merged with a 22 year series of district level rainfall data ex ante households facing riskier distributions of rainfall are more likely to participate in the labor market ex post unexpectedly bad weather and low rainfall increase labor force participation

trade liberalization and environmental taxation in federal systems the literature on trade liberalization and environment has not yet considered federal structures in this paper we show how the design of environmental policy in a federal system has implications for the effects of trade reform trade liberalization leads to a decline in pollution taxes regardless of whether pollution taxes are set at the federal centralized or local decentralized level and it increases social welfare the effect under a decentralized system is smaller than if these taxes are set by the federal government and pollution emissions therefore decline in this case moreover majority bias interacts with trade liberalization if federal taxes are used

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

does migration raise agricultural investment an empirical analysis for rural mexico the effect of remittances on capital accumulation remains a contested topic this paper uses a panel data set from rural mexico to investigate the impact of remittances on agriculture and livestock investments after controlling for the endogeneity of migration through an instrumental variable estimation our empirical results show that international migration has a significantly positive effect on the accumulated agricultural assets but not on livestock capital this suggests that households use the capital obtained from international migration only to overcome liquidity constraints for subsistence production whereas migration itself seems to be the superior investment option compared to other productive activities such as livestock husbandry

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

the impact of macroeconomic policies on income distribution an empirical study of the philippines there has been a growing awareness of the income distribution dimension of macroeconomic policies this paper studies this issue empirically considering the case of the philippines and using data available from integrated surveys of households after estimating a reduced form equation it was found that underemployment inflation and government spending worsen income distribution while productivity gains the real interest rate and the real exchange rate were found to improve distribution a similar pattern emerges when the effects of these variables on the absolute incidence of poverty are estimated excerpt

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

the political economy of pollution taxes in a small open economy abstract this paper develops a positive theory explaining pollution tax policy outcomes in a small open economy the equilibrium tax rate depends on lobby group membership the relative importance of lobbying activities and the tax elasticity of pollution the equilibrium properties are investigated the model is extended to incorporate pollution abatement and a pollution abatement subsidy we show that total pollution may be increasing in the pollution abatement subsidy rate this effect arises because the equilibrium pollution tax rate may be decreasing in the subsidy rate due to altered political influence of the lobby groups in the political equilibrium

heterogeneous returns to chemical fertilizer at the intensive margins insights from nepal increased fertilizer use is considered important for agricultural development in low income countries promoting increased use of chemical fertilizer by lowering its price may be ineffective if demand is price inelastic in theory the price elasticity of demand depends on the returns to its use but the evidence is scarce furthermore while returns are often estimated for small changes in chemical fertilizer use returns to larger changes in its use intensive margins are less understood through the inter zonal comparisons in nepal we provide indicative evidence that greater returns to chemical fertilizer are associated with greater price elasticities of demand moreover the evidence suggests that returns at the intensive margins rather than returns to small changes may largely account for inter zonal differences in returns to chemical fertilizer within nepal the results suggest that better understanding the returns at the intensive margins is critical for effective agricultural inputs policies in developing countries

nonstructural risk attitude estimation this paper presents an econometric approach to risk attitude estimation that does not require joint estimation of the structure of the firm s technology and input decision rules the nonstructural approach replaces optimal input choice with the assumption that farmers optimally manage their portfolios of productive activities by thus shifting the focus from the detailed production decisions of the farm manager to the net returns of the whole farm operation the modeling problem is simplified the nonstructural approach is used to estimate risk attitudes in three indian villages the results are compared to previous experimental and econometric estimates from the same villages

the complex dynamics of smallholder technology adoption the case of sri in madagascar this article explores the dynamics of smallholder technology adoption with particular reference to a high yielding low external input rice production method in madagascar we present a simple model of technology adoption by farm households in an environment of incomplete financial and land markets we then use a probit model and symmetrically censored least squares estimation of a dynamic tobit model to analyze the decisions to adopt expand and disadopt the method we find that seasonal liquidity constraints discourage adoption by poorer farmers learning effects both from extension agents and from other farmers exert significant influence over adoption decisions

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

trade facilitation and economic development new approach to quantifying the impact this article analyzes the relationship between trade facilitation and trade flows in the asia pacific region country specific data for port efficiency customs environment regulatory environment and e business usage are used to construct indicators for measuring trade facilitation the relationship between these indicators and trade flows is estimated using a gravity model that includes tariffs and other standard variables enhanced port efficiency has a large and positive effect on trade flows regulatory barriers deter trade improvements in customs and greater e business use significantly expand trade but to a lesser degree than improvements in ports or regulations the benefits of specific trade facilitation efforts are estimated by quantifying differential improvements in these four areas among members of the asia pacific economic cooperation apec a scenario in which apec members with below average indicators improve capacity halfway to the average forall members shows that intra apec trade could increase by dollar 254 billion or 21 percent of intra apec trade flows

decomposing interregional differentials in productivities an empirical analysis for japanese data abstract we propose a method for decomposing interregional differentials in productivities based on the lifecycle permanent income hypothesis we also conduct an empirical analysis using japanese prefectural data and examine the effectiveness of this method

a new approach to the economic inequality based upon the permanent income hypothesis abstract we propose a new inequality measure based upon the permanent income hypothesis tracing its historical changes in japan we compare it with some traditional inequality measures for the income distribution

political internalization of economic externalities and environmental policy abstract this paper derives the characteristics of endogenous environmental policy in a common agency model of politics and proceeds to show that competition between lobby groups is an important source of internalization of economic externalities our analysis generalizes bhagwati s principle of targeting to the case of distorted political markets moreover we show that the politically optimal structure of environmental taxes incorporates a pigouvian adjustment however since lobby groups care about the distribution of income as well as about efficiency the equilibrium structure of taxes differs considerably from the pigouvian rule

incorporating risk in production analysis risk is the farmer s perennial problem unfortunately agricultural economists have made little progress in analyzing or measuring production risk in ways that provide useful information for farm management therefore it is fair to say that the social returns to existing research on production risk are probably low it is from this perspective that i will discuss incorporating risk in production analysis my purpose is not to survey the literature or to catalog all the ways risk concepts have been incorporated in production models rather i intend to evaluate critically some of the basic concepts and approaches in the literature and to indicate the directions i believe research must take to arrive at a paradigm for incorporating risk in production analysis that could yield higher social returns in my view the conventional conceptual framework used for risk analysis has not led agricultural economists to ask the most important questions about the effects risk has on agricultural decision making the extension of the static neoclassical production model to incorporate price and production uncertainty has led agricultural economists to rationalize observed behavior in terms of the arrow pratt risk aversion concept this approach has led in turn to qualitative comparative static theorems which are appealing to theorists but have little relation to the decision problems farmers face to increase the relevance of their models and methods i believe agricultural economists need to understand specifically how risk affects agricultural production this in turn will suggest how risk affects agricultural decision making and why farmers are or should be concerned with it my analysis of these issues leads me to discount the hypothesis that risk matters primarily because of the psychic disutility it causes rather i hypothesize that risk matters primarily because production is a dynamic phenomenon and therefore production and price uncertainty affect expected productivity and expected income i hypothesize that these firstorder effects are why farmers are and should be concerned with risk the analysis of dynamic uncertain models shows that farmers optimal decisions are affected by risk whether they are risk neutral or risk averse this suggests that dynamic risk neutral models may be more useful than conventional static risk averse models for understanding the role production risk plays in farm management

adoption of agricultural innovations in developing countries a survey this paper reviews various studies which have provided a description and possible explanation to patterns of innovation adoption in the agricultural sector the survey points out that the tendency of many studies to consider innovation adoption in dichotomous terms adoption nonadoption may not be appropriate in many cases where the actual decisions are defined over a more continuous range more attention needs to be given to the socio cultural and institutional environment in area studies so that their interrelation with economic factors affecting adoption can be inferred the presence of several interrelated innovations is another aspect that needs to be considered more carefully in future research since a number of simultaneous decisions may be involved furthermore the possibility of regular sequential patterns in adopting components of a new technological package should be specifically addressed in future studies finally the impact of differential adoption rates on land holding distribution merits attention in future research

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

agricultural technology choice and transport this paper addresses an old and recurring theme in development economics the slow adoption of new technologies by farmers in many developing countries the paper explores a somewhat novel link to explain this puzzle the link between market access and the incentives to adopt a new technology when there are non convexities the paper develops a theoretical model to guide the empirical analysis which uses spatially disaggregated agricultural production data from spatial production allocation model and living standards measurement study survey data for nigeria the model is used to estimate the impact of transport costs on crop production the adoption of modern technologies and the differential impact on returns of modern versus traditional farmers to overcome the limitation of data availability on travel costs for much of africa road survey data are combined with geographic information road network data to generate the most thorough and accurate road network available with these data and the highway development management model minimum travel costs from each location to the market are computed consistent with the theory analysis finds that transportation costs are critical in determining technology choices with a greater responsiveness among farmers who adopt modern technologies and at times a perverse negative response to lower transport costs among those who employ more traditional techniques in sum the paper presents compelling evidence that the constraints to the adoption of modern technologies and access to markets are interconnected and so should be targeted jointly

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

pollution policy and trade liberalization of environmental goods during the doha round at the world trade organization reductions in trade barriers on environmental goods eg were put forward as a means of helping developed and developing countries alike deal with current environmental problems we examine the potential effectiveness of such a strategy in a developing country that imports all its consumption of eg from an imperfectly competitive foreign eco industry we point out that trade liberalization of eg might in fact lead to less stringent pollution taxes which can result in an actual rise in pollution levels we then show that the environmental effectiveness objective of this trade reform can be achieved when the regulator uses quantitative abatement standards as an alternative pollution policy instrument however this environmental achievement comes at the expense of social welfare

consumption and income seasonality in thailand many households in developing countries rely on seasonal agriculture for their incomes this paper investigates whether household consumption expenditure tracks income across seasons using data from thailand i contrast the seasonal consumption patterns of households with different seasonal income patterns and estimate the responsiveness of seasonal consumption to seasonal income i find little evidence that consumption tracks income over the course of the year the findings suggest that observed seasonal consumption patterns are the result of seasonal variations in preferences or prices common to all households rather than an inability of households to use savings behavior to smooth consumption

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

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

trade wars and trade talks when governments meet in the international arena their actions reflect the political situations at home previous studies of trade relations have focused on governments that are immune from political pressures and that act as benevolent servants of the public interest here we introduce domestic politics into the analysis of international economic relations we study the interactions between national leaders who are concerned both with providing a high standard of living to the general electorate and collecting campaign contributions from special interest groups our analysis sheds light on the determinants of the structure of protection in non cooperative and cooperative policy equilibria

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

productivity credit risk and the demand for weather index insurance in smallholder agriculture in ethiopia the article explores the relationship between fertilizer use and the demand for weather index insurance wii among smallholder farmers in ethiopia we examine whether fertilizer use is profitable under current smallholder production conditions whether risk related factors affect fertilizer use and we estimate the returns to inputs in the agricultural production function in the absence of insurance we then study how these primitives of agricultural production functions relate to insurance demand the study compares a survey based estimate of willingness to pay with actual uptake for the weather insurance finding the stated and actual demand to be almost completely uncorrelated while those with high marginal returns to inputs say they would purchase insurance only those with low marginal returns actually do consistent with the stated purpose of the product as input insurance insurance demand proves to be highly responsive to the existence and amount of randomly allocated insurance vouchers jel classifications c83 g22 q12

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

saving two in a billion quantifying the trade effect of european food safety standards on african exports abstract a growing concern over health risks associated with food products has prompted close examination of sanitary and phytosanitary standards in industrialized countries this paper quantifies the impact of a new harmonized aflatoxin standard set by the eu on food exports from africa we employ a gravity model to estimate the impact of changes in differing levels of protection based on the eu standard in contrast to those suggested by international standards the analysis is based on trade and regulatory survey data for 15 european countries and nine african countries between 1989 and 1998 our results suggest that the implementation of the new aflatoxin standard in the eu will have a negative impact on african exports of cereals dried fruits and nuts to europe the new eu standard which would reduce health risk by approximately 1 4 deaths per billion a year will decrease these african exports by 64 or us 670 million in contrast to regulation set through an international standard

interest groups trade liberalization and environmental standards in considering a country that imposes a minimum standard on an imported polluting good which generates negative consumption externalities we construct a common agency model in which a domestic environmental group and a foreign industrial lobby can influence the formation of the minimum standard by providing political contributions to the government this paper investigates the effects of trade liberalization on the political equilibrium environmental standard the pattern of trade environmental disutility and social welfare we find that trade liberalization tightens the minimum standard decreases imports of the polluting good and reduces environmental disutilities the importing country s social welfare however does not necessarily increase with trade liberalization the weaker the environmental group s lobbying efficiency or the stronger the foreign firm s lobbying efficiency the more likely it is that trade liberalization will enhance the importing country s welfare

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

consumption risk technology adoption and poverty traps evidence from ethiopia much has been written on the determinants of input and technology adoption in agriculture with issues such as input availability knowledge and education risk preferences profitability and credit constraints receiving much attention this paper focuses on a factor that has been less well documented the differential ability of households to take on risky production technologies for fear of the welfare consequences if shocks result in poor harvests building on an explicit model this is explored in panel data for ethiopia historical rainfall distributions are used to identify the counterfactual consumption risk controlling for unobserved household and time varying village characteristics it emerges that not just ex ante credit constraints but also the possibly low consumption outcomes when harvests fail discourage the application of fertilizer the lack of insurance causes inefficiency in production choices
