policy watch child support policies with more parents living apart the societal problem of parents who fail to share with each other or with their children becomes more acute although governments have mainly relied on public transfers to address the resulting economic hardships among children the emphasis has been shifting toward mandatory sharing through the rigorous enforcement of child support laws this paper first describes the economic context for child support the expanding federal role in regulating awards and collections the complex array of incentive and equity effects associated with child support the record of obtaining support payments from noncustodial parents and the effects of new award setting and enforcement policies finally it considers the child support assurance system csas approach recently proposed in congress under this plan the government would make up the difference between some minimum assured payment and the child support actually paid by the non custodial parent

marriage market divorce legislation and household labor supply this paper provides a theoretical framework for analyzing the impact of the marriage market and divorce legislation on household labor supply in our approach the sex ratio in the marriage market and the rules governing divorce are examples of distribution factors these factors are defined as variables that affect the household members bargaining position but not preferences or the joint budget set we extend the collective labor supply model developed by chiappori to allow for distribution factors we show that our model imposes new restrictions on the labor supply functions and eases the identification of individual preferences and the intrahousehold decision process the model is estimated using psid data for the year 1988 our results do not reject the restrictions imposed by the model also the sex ratio and divorce laws deemed favorable to women are found to affect labor supply behavior and the decision process in the directions predicted by the theory and to have sizable effects

realizing the gains from trade export crops marketing costs and poverty this paper explores the role of export costs in the process of poverty reduction in rural africa the authors claim that the marketing costs that emerge when the commercialization of export crops requires intermediaries can lead to lower participation into export cropping and thus to higher poverty they test the model using data from the uganda national household survey the findings show that i farmers living in villages with fewer outlets for sales of agricultural exports are likely to be poorer than farmers residing in marketendowed villages ii market availability leads to increased household participation in export cropping coffee tea cotton fruits and iii households engaged in export cropping are less likely to be poor than subsistence based households the authors conclude that the availability of markets for agricultural export crops helps realize the gains from trade this result uncovers the role of complementary factors that provide market access and reduce marketing costs as key building blocks in the link between the gains from export opportunities and the poor

spousal conflict and divorce the optimal balance between keeping marriages intact despite spousal conflict and allowing for divorce is a subject of policy debate in the united states to explore the trade offs i construct a structural model with information asymmetries which may generate inefficient outcomes parameters are estimated using data from the national survey of families and households i find that eliminating separation periods decreases the conflict rate by 9 2 of its baseline level and increases the divorce rate by 4 0 perfect child support enforcement decreases the frequency of conflict and divorce by 2 7 and 21 2 respectively and reduces the incidence of inefficient divorces

a comment on why did child support award levels decline from 1978 to 1985 by philip k robins between 1978 and 1985 the mean real value of child support payments due declined 25 percent in this journal philip robins argued most of this decline was the result of an increase in the ratio of female to male earnings but we argue his conclusion is based upon an inappropriate use of decomposition analysis we show child support due declined largely as a result of a secular decline in the real value of new awards which have fallen almost three percent per year since 1961 and we investigate why new awards declined our findings have implications for reforms contained in the family support act of 1988

monopsony power in migrant labor markets evidence from the united arab emirates by exploiting a reform in the united arab emirates that relaxed restrictions on employer transitions we provide new estimates of the monopsony power of firms over migrant workers our results show that the reform increased incumbent migrants earnings and firm retention this occurs despite an increase in employer transitions and is driven by a fall in country exits while the outcomes of incumbents improved the reform decreased demand for new migrants and lowered their earnings these results are consistent with a model of monopsony in which firms face upward sloping labor supply curves for both new recruits in source countries and incumbent migrants

did unilateral divorce laws raise divorce rates a reconciliation and new results application of the coase theorem to marital bargaining suggests that shifting from a consent divorce regime to no fault unilateral divorce laws should not affect divorce rates each iteration of the empirical literature examining the evolution of divorce rates across us states has yielded different conclusions about the effects of divorce law liberalization i show that these results reflect a failure to jointly consider both the political endogeneity of these divorce laws and the dynamic response of divorce rates to a shock to the political regime taking explicit account of the dynamic response of divorce rates to the policy shock i find that liberalized divorce laws caused a discernible rise in divorce rates for about a decade but that this increase was substantially reversed over the next decade that said this increase explains very little of the rise in the divorce rate over the past half century both administrative data on the flow of new divorces and measures of the stock of divorcees from the census support this conclusion these results are suggestive of spouses bargaining within marriage with an eye to their partner s divorce threat

marriage divorce and asymmetric information we use data on people s valuations of options outside marriage and beliefs about spouses options the data demonstrate that in some couples one spouse would be happier and the other spouse unhappier outside of some marriages suggesting that bargaining takes place and that spouses have private information we estimate a bargaining model with interdependent utility that quantifies the resulting inefficiencies our results show that people forgo some utility in order to make their spouses better off and in doing so offset much of the inefficiency generated by their imperfect knowledge thus we find evidence of asymmetric information and interdependent utility in marriage

the impact of legislation on divorce a hazard function approach the paper examines the impact of the introduction of no fault divorce legislation in australia the approach used is rather novel a hazard model of the divorce rate is estimated with the role of legislation captured via a time varying covariate the paper concludes that contrary to us empirical evidence no fault divorce legislation appears to have had a positive impact upon the divorce rate in australia

an economic model of cohabitation and divorce abstract the positive correlation between the rates of cohabitation and divorce has long been established this paper seeks to determine the direction of causation between these two variables a simultaneous equations model is specified with cohabitation and divorce rates as endogenous variables and using data aggregated to the state level for 1990 this procedure suggests that the divorce rate is a significant factor in explaining variations across states in the cohabitation rate and that the divorce rate is itself influenced by cohabitation behavior this finding strengthens the results put forth by various economic and sociological single equation studies this synthesis of information and data provided by sociologists with economic theory and methodology suggests further research in modelling demographic variables as joint outcomes of the same process

no fault divorce laws and the labor supply of women with and without children we use a difference in difference in difference estimator to compare changes in labor force participation weeks and hours of work associated with no fault divorce laws allowing for differential responses for married women with and without children although other research has found that the labor supply of women in general does not respond to no fault divorce laws we find that no fault divorce laws are associated with increases in the labor supply of married mothers relative to married nonmothers even after controlling for changes in female labor supply in states without no fault divorce laws and for property division rules associated with the laws

married womens tastes and the decision to participate in the labour market results from a fixed effects model in the paper we report estimates from two logit models of women s labour force participation a model with out fixed effects estimated from cross sectional data indicates a significant postive relation between work experience and particiption we ask whether the relation is due to a causal influence extered by the former variable on the latter or to a common underlying variable taste for market attachement to answer this question we present results from a fixed effects model estimated from panel data in this model the estimated coefficients of experience are insignificant suggestion that a taste for market attachement underlies both experience and participation is the presence of preschool children

until death do you part the effects of unilateral divorce on spousal homicides this study examines how the widespread adoption of unilateral divorce influenced the prevalence of lethal spousal violence in the united states these evaluations are based on fixed effects specifications for spousal homicide counts from an annual panel of u s states from 1968 to 1978 the results indicate that unrestricted unilateral divorce laws had small and statistically insignificant effects on the amount of lethal spousal violence directed against wives however the easy access to divorce created by such laws increased spousal homicides of husbands by approximately 21 these increases were concentrated in states where the division of marital property favored husbands

migrations risks and uncertainty a field experiment in china abstract we report data from the first incentivized artefactual field experiment conducted in china to understand whether chinese migrants differ from non migrants in terms of preferences regarding risk and uncertainty in various contexts we find that compared to non migrants migrants are significantly more likely to enter competitions when they expect competitive entries from others however migrants are not different from non migrants in risk and ambiguity preferences where strategic uncertainty is absent our results suggest that migration may be driven more by a stronger belief in one s chance of succeeding in an uncertain competitive environment than by differences risk attitudes related to state uncertainty

the feminist challenge to neoclassical economics this paper describes a feminist research agenda within economics how some of the research priorities have been accommodated within neoclassical economics and how others fundamentally challenge the neoclassical economic paradigm there are three major challenges to neoclassical economics raised by feminists first women are invisible in much economic analysis and this situation needs to be remedied second tests may be affected by educational social and economic institutions we need a feminist model of endogenous preferences and to incorporate the endogeneity of preferences into welfare economic analysis and policy recommendations finally institutional structures matter and deserve careful analysis c 1993 academic press inc copyright 1993 by oxford university press

the impact of divorce laws on marriage specific capital this article considers how divorce law alters the incentives for couples to invest in their marriage focusing on the impact of unilateral divorce laws on investments in new marriages differences across states between 1970 and 1980 provide useful quasi experimental variation with which to consider incentives to invest in several types of marriagespecific capital spouse s education children household specialization and home ownership i find that adoption of unilateral divorce regardless of the prevailing property division laws reduces investment in all types of marriage specific capital considered except home ownership in contrast results for home ownership depend on the underlying property division laws

domestic violence and divorce law when divorce threats become credible the cost of divorce influences the bargaining position of spouses and thus their behavior within the marriage this study takes advantage of a major and unexpected reduction in divorce costs in spain to estimate the causal effects on domestic violence results suggest a 30 decline in spousal conflict as a consequence of the reform spousal violence is found to have decreased among couples who remained married after the modification in the law which suggests an important role for changes in bargaining within the marriage when divorce becomes a more credible cheaper option

the digital provide information technology market performance and welfare in the south indian fisheries sector when information is limited or costly agents are unable to engage in optimal arbitrage excess price dispersion across markets can arise and goods may not be allocated efficiently in this setting information technologies may improve market performance and increase welfare between 1997 and 2001 mobile phone service was introduced throughout kerala a state in india with a large fishing industry using microlevel survey data we show that the adoption of mobile phones by fishermen and wholesalers was associated with a dramatic reduction in price dispersion the complete elimination of waste and near perfect adherence to the law of one price both consumer and producer welfare increased

bargaining in the shadow of the law divorce laws and family distress this paper exploits the variation occurring from the different timing of divorce law reforms across the united states to evaluate how unilateral divorce changed family violence and whether the option provided by unilateral divorce reduced suicide and spousal homicide unilateral divorce both potentially increases the likelihood that a domestic violence relationship ends and acts to transfer bargaining power toward the abused thereby potentially stopping the abuse in extant relationships in states that introduced unilateral divorce we find a 8 16 percent decline in female suicide roughly a 30 percent decline in domestic violence for both men and women and a 10 percent decline in females murdered by their partners

sin city why is the divorce rate higher in urban areas divorce rates are higher in cities based on danish register data this paper shows that of the marriages formed in the city those couples who remain in the city have a 23 higher divorce rate than those who move out in this paper we test whether this observation is due to sorting of more stable marriages into rural areas or if there exists a causal effect of living in urban areas on marriage instability our identification strategy supplements the timing of events approach with an instrumental variable our findings suggest that the effect of living in an urban area on the divorce risks drops substantially and loses statistical significance once we address sorting keywords divorce search mobility city keywords j12 j64

fertility and the size of the u s labor force this paper reviews and interprets from an economic perspective the demographic trends in the u s since the turn of the century the primary focus will be upon the interplay between the fertility and labor force participation of women and how they may be interpreted within simple economic models we will begin by stating what economic demography is and why careful analytic methods are needed section ii provides a brief demographic history of the u s section iii describes the major economic theories of fertility and section iv discusses the empirical performance of these theories section v discusses the linkages between fertility and the size of the labor force and section vi concludes excerpt

marriage and divorce reply in the popular press and among policymakers the effect of no fault divorce laws on divorce rates remains an issue see e g new york times 23 july 1991 in my 1986 article in this review i show that the adoption of one form of no fault divorceunilateral divorce does not lead to a significant increase in divorce rates the theoretical model that is consistent with this empirical evidence would imply that the new law does not decrease the costs of divorce it merely redefines which party has the right to terminate the marriage

divorce risk wages and working wives a quantitative life cycle analysis of female labour force participation this article develops a quantitative life cycle model to study the increase in married women s labour force participation lfp we calibrate the model to match key life cycle statistics for the 1935 cohort and use it to assess the changed environment faced by the 1955 cohort we find that a higher divorce probability and changes in wage structure are each able to explain a large proportion of the lfp increase higher divorce risk increases lfp not because the latter contributes to higher marital assets or greater labour market experience however instead it is the result of conflicting spousal preferences towards the adjustment of marital consumption in the face of increased divorce risk the dramatic increase in the second half of the twentieth century in married women s labour force participation lfp has given rise to a large and growing literature that explores the roles of the multiple forces that led to this evolution some explanations have emphasised technological change in the household greenwood et al 2005 or in medical contraceptive technology goldin and katz 2002 albanesi and olivetti 2009a b knowles 2007 other explanations have emphasised changes in the wage

changes in labor force participation in the united states the labor force participation rate in the united states increased almost continuously for two and a half decades after the mid 1960s pausing only briefly during economic downturns the pace of growth slowed considerably during the 1990s however and after reaching a record high of 67 3 percent in the first quarter of 2000 participation had declined by 1 5 percentage points by 2005 this paper reviews the social and demographic trends that contributed to the movements in the labor force participation rate in the second half of the twentieth century it also examines the manner in which developments in the 2000s reflect a break from past trends and considers implications for the future

the effect of joint custody on family outcomes since the 1970s almost all us states have introduced a form of joint custody after divorce i analyze the causal effect of these custody law reforms on different family outcomes my identification strategy exploits the different timing of reforms across the us states estimations based on state panel data suggest that the introduction of joint custody led to an increase in marriage rates an increase in overall fertility including a shift from nonmarital to marital fertility and an increase in divorce rates for older couples accordingly female labor market participation decreased further male suicide rates and domestic violence fell in treated states the empirical evidence is consistent with the hypothesis that joint custody increased the relative bargaining power of men within marriage

marriage and trust some lessons from economics this paper examines the role of marriage as an institution for providing couples with the confidence to make long term investments in their relationship no fault divorce has undermined the notion of marriage as a contract thereby reducing the security offered by marriage and promoting opportunism by men this has weakened the bargaining power of wives both within marriage and when divorce occurs current legal reforms will improve the economic position of all divorced wives including those who are primarily responsible for the breakdown of their marriage the latter feature will encourage opportunism by women and make men less prepared to invest in their marriage the paper argues that the only way to achieve parity between men and women and deter opportunism by either sex is to return to fault based divorce both divorce settlements and the custody of children should depend on preceding marital conduct

on the optimal choice of capital intensity in ldcs with migration abstract sen s classic work on the choice of capital intensity of investment is generalized in the light of new theoretical developments and empirical findings concerning rural to urban migration in ldcs this is done by explicitly incorporating a migration function into the basic choice model revised conditions for maximization of surplus are derived and compared with sen s original condition some justification for the particular migration function used in the presence of risk aversion is suggested

yours mine and ours do divorce laws affect the intertemporal behavior of married couples divorce laws establish spouses individual property rights over household resources and determine when divorce is allowed this paper examines how such laws inuence the intertemporal behavior and the welfare of u s married couples i build a model of household choice about consumption labor supply and divorce under multiple divorce law regimes and i estimate it using exogenous variation in u s divorce laws from the 1970s to the 1990s couples responded to equal division of property and unilateral divorce by increasing tangible assets up to 19 which suggests the presence of a strong income eect for the primary earner and by reducing female employment by over 5 percentage points because the threat of divorce granted additional bargaining power to married woman the bargaining weight of women implied by these responses in the model corresponds to a third of the weight of men this indicates that equal division of assets beneted women when it was

marriage and divorce changes and their driving forces the family is not a static institution in recent decades marriage rates have fallen divorce rates have risen and the defining characteristics of marriage have changed the economic approach to the family seeks to explain these trends by reference to models that can also explain how and why families form gary becker s 1981 treatise on the family proposed a theory based on production complementarities in which husband and wife specialize in the market and domestic spheres respectively production complementarities also arise in the production and rearing of one s own children however production complementarities at least as initially described are decreasingly central to modern family life increased longevity and declining fertility mean that most of one s adult life is spent without one s own children in the household also the rise in marital formation at older ages including remarriage means that many families form with no intention of producing children moreover increases in female labor force participation suggest that household specialization has either declined or at least taken on a different meaning these changes have come about as what is produced in the home has been dramatically altered both by the emergence of labor saving technology in the home and by the development of service industries that allow much of what was once provided by specialized homemakers to be purchased in the market the availabil

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

taxes and transfers their effects on the decision to end a marriage abstract the transfer system typically has large marriage disincentives while the income tax system is likely to subsidize marriage for many low income families in other words the tax system may offset an increase in transfer benefits associated with marital separation the interaction of the transfer system with the income tax system has largely been overlooked the income tax system has become more relevant for low income families with the recent expansion of the earned income tax credit which filers may be eligible for even if their tax liability is zero this paper uses family level measures of the change in transfer benefits and tax liability associated with a change in family structure to consider the effect of these financial incentives on separation decisions

risk aversion time preferences and out migration experimental evidence from ghana and indonesia abstract it has long been hypothesized that migrants and non migrants differ in their individual risk and time preferences due to a lack of reliable data on migrants preferences empirical evidence however is scarce therefore this paper has sought to advance research on preferences and migration decisions by using original household survey data from two developing countries that are both characterized by a longstanding tradition in regional migration in coastal communities in ghana and indonesia individual risk and time preferences have not only been elicited through survey questions but also through experimental tasks with real and relatively large monetary payoffs there is evidence that out migrants from both study regions are significantly less risk averse and have a lower time preference than non migrants overall the results indicate that the considered individual preferences are as important as employment status education or networks which have mainly been the focus of migration theories

female labor supply and divorce new evidence from ireland if participation in the labor market helps to secure women s outside options in the case of divorce separation an increase in the perceived risk of marital dissolution may accelerate the increase in female labor supply this simple prediction has been tested in the literature using time and or spatial variation in divorce legislation e g across us states leading to mixed results in this paper we suggest testing this hypothesis by exploiting a more radical policy change i e the legalization of divorce in ireland the right to divorce was introduced in 1996 followed by an acceleration of marriage breakdown rates we use this fundamental change in the irish society as a natural experiment we follow a difference in difference approach using families for whom the dissolution risk is small as a control group our results suggest that the legalization of divorce contributed to a significant increase in female labor supply mostly at the extensive margin results are not driven by selection and are robust to several specification checks including the introduction of household fixed effects and an improved match between control and treatment groups using propensity score reweighting

divorce law reforms and divorce rates in the usa an interactive fixed effects approach this paper estimates the eects of unilateral divorce laws on divorce rates from a panel of state level divorce rates we use the interactive xed eects model to address the issue of endogeneity due to the association between cross state unobserved heterogeneity and divorce law reforms we document that earlier studies in the literature do not fully control for unobserved heterogeneity and result in mixed empirical evidence on the eects of divorce law reforms our results while reconciling these conicting results suggest that divorce law reforms have positive eects on divorce rates but the magnitude and duration of the eects

law property and marital dissolution this paper challenges the view that legal rights are not important in affecting whether people divorce but it puts as much emphasis on property rights given for example by the law on alimony as on dissolution rights in the united states the paper sets out two stylised models of marriage and examines the consequences of fuller compensation for economic sacrifices made during marriage if the dominant economic issue in a marriage is who undertakes household tasks then a law giving fuller compensation makes divorce more likely if the dominant issue is child custody divorce is less likely excerpt

divorce rates and bankruptcy exemption levels in the united states abstractalthough increasing bankruptcy exemption levels protects consumers from negative asset shocks an unintended consequence of this policy that remains unexplored is the effect on divorce rates this effect arises from reducing the benefits of marital risk sharing i establish conditions under which increases in exemption levels lead to more divorce and investigate using data from vital statistics of the united states i estimate that increases in exemption levels occurring between 1989 and 2005 resulted in more than 200 000 additional divorces during this period and that the effect on divorce rates in 2005 is comparable in magnitude to that found for the introduction of unilateral divorce laws by wolfers

changing the rules midway the impact of granting alimony rights on existing and newly formed partnerships this article analyses the effect of a reform granting alimony rights to cohabiting couples in canada a collective household model with a matching framework predicts that changes in alimony laws would affect existing couples and couples to be differently for existing couples it benefits the intended beneficiary but for couples not yet formed it generates offsetting intra household transfers and lower intra marital allocations for the beneficiary our empirical analyses confirm these predictions among couples united before the reform obtaining the right to petition for alimony led women to lower their labour force participation but not among newly formed cohabiting couples

why have divorce rates fallen the role of women s age at marriage american divorce rates rose from the 1950s to the 1970s peaked around 1980 and have fallen ever since the mean age at marriage also substantially increased after 1970 i explore the extent to which the rise in age at marriage can explain the decrease in divorce rates for cohorts marrying after 1980 using data from the survey of income and program participation 1979 national longitudinal survey of youth and national survey of family growth three different empirical approaches suggest that the increase in women s age at marriage is the main proximate cause of the fall in divorce rates

what determines family structure i introduction the most prevalent type of family structure in which children in the united states are raised today is the traditional one in which both biological parents are present in the home and married but in the past 30 40 years it has become increasingly common for children to experience alternative family structures such as living with the mother with no father present the mother and a stepfather and cohabiting parents children who grow up in a family with married biological parents have better education employment marriage childbearing and psychological outcomes on average than their counterparts who spend substantial parts of childhood living in alternative family structures 1 these differences are generally quite large and dwarf the effects of income and maternal employment the evidence suggests that at least part of the association between family structure and child outcomes is causal there is much still to be learned about the consequences of growing up in alternative family structures but there is a consensus that family structure matters for child development in contrast there is much less known about the determinants of family structure the proximate determinants of family structure are well studied demographic behaviors union formation and dissolution transition from cohabitation to marriage and fertility both in and outside of unions but the implications of adult demographic behaviors for the family structure experiences of children depend crucially on interactions among these behaviors for example the impact on a child of being born out of wedlock is likely to depend on whether the mother and biological father subsequently marry or cohabit and if so how soon after the birth of the child the impact on a child of the dissolution of a union may depend on whether the man in the union was the child s biological father or a stepfather and on the duration of the union economic theories of family formation and dissolution suggest a number of observable factors that affect the demographic behaviors that determine family structure 2 these include the wage rates available to men and women the tax and transfer incentives to cohabit marry and bear children the legal environment governing divorce and child support provided by absent parents and the state of the marriage market many studies have examined the effects of these factors on the family structure experiences of children but most have taken a narrow approach for example a typical study examines the impact of changes over time in one or two determinants of family structure without considering the implications of simultaneous changes in other factors most studies examine only one or two of the key demographic behaviors that determine the family structure experienced by children for example one study might focus only on entry to cohabitation and marriage whereas another study examines childbearing while single and a third study analyzes marital dissolution in this article we propose a new approach to analyze the determinants of the family structure experiences of children our approach has four distinguishing features first we jointly model union formation union dissolution and childbearing decisions previous analyses have integrated some of these behaviors in a single model but none has integrated the full range of behaviors needed for a thorough analysis of family structure a major feature of change in recent years has been de linking of marriage and childbearing decisions hence it is crucial to recognize as emphasized by ellwood and jencks 2004 that marriage and childbearing are in fact distinct decisions and that treating single parenthood as one decision rather than the consequence of related but distinct union and childbearing decisions misses key elements of changes in behavior furthermore bumpass and lu 2000 point out that a substantial part of the increase in single parenthood in the last three decades can be accounted for by a rise in the presence of children with cohabiting parents but child outcomes are worse in cohabitation than marriage other things equal

enhancing nutrition a new tool for ex ante comparison of commodity based vouchers and food transfers summary this article presents a new analytical tool for ex ante comparison of the cost effectiveness of two transfer modalities in pursuing specific nutritional objectives it does so by introducing a metric to score the nutrient value of a food basket the nutrient value score nvs and explains how this metric can be combined with full supply chain analysis and costing to generate a new tool the omega value the use of the omega value allows policy makers who design a program with nutrition objectives to compare direct food transfers and commodity based food vouchers in terms of both cost efficiency and cost effectiveness 2013 elsevier ltd all rights reserved

informal export barriers and poverty the author investigates the poverty impacts of informal export barriers like transport costs cumbersome customs practices costly regulations and bribes he models these informal barriers as export taxes that distort the efficient allocation of resources in low income agricultural economies this distortion lowers wages and household agricultural income thereby leading to higher poverty the author investigates the poverty impacts of improving export procedures in moldova this is a unique case study poverty is widespread half of the moldovan population lives in poverty the country is very open and relies on agricultural exports for growth formal trade barriers are fairly liberalized and informal export barriers are common and widespread the author finds that improving export practices would benefit the average moldovan household across the whole income distribution for example halving informal export barriers would cause poverty to decline from 48 3 percent of the population to between 43 3 and 45 5 percent potentially lifting 100 000 180 000 individuals out of poverty

marital division of labor with risk of divorce the role of voice enforcement of contracts it is assumed that emotional ties can be relied on to enforce implicit marital contracts by voice therefore in the present model divorce has economic consequences not only because the economies of scale from living together are destroyed but also because the scope for such voice enforcement is weakened moreover perhaps surprisingly i find that it is ambiguous how an increase in the probability of divorce influences predivorce allocation of time even when preferences are assumed to be homothetic

rural urban migration in economic development abstract this paper provides a review of the theoretical literature on rural urban migration in contemporary ldcs the paper begins with a brief discussion of the lewis model before going on to discuss the todaro and the harris todaro models and the large literature which these models have spawned the question of job search in the context of migration and the role of family members in migration decisions are considered next the paper then takes a closer look at the informal sector and also sets out alternative migration functions to the ones usually employed in the literature the paper concludes with a brief note on some of the important implications arising from our study

migration growth distribution and welfare abstract in this note we argue that the inverted u curve of inequality is a technical derivative of the attributes of the conventional indices of inequality that these indices are inadequate measures of the change in welfare associated with the typical distributional consequences of rural to urban migration and that an explicit welfare judgment with respect to this process should and can be made

the economics of child custody i develop a model of marriage in which spouses decide on investments in child quality during marriage and on the allocation of child custody should they divorce the custodial allocation determines the share of the marital surplus each spouse appropriates which in turn influences spouses investment incentives the custodial allocation therefore has both distributional and efficiency consequences i derive the equilibrium investments and optimal custodial allocation and identify three channels through which making divorce easier affects child welfare investments in child quality during marriage the likelihood of divorce and the allocation of custody if divorce occurs

alimony rights and intrahousehold allocation of resources evidence from brazil can family policy affect well being of individuals without altering the resources available to their families this article examines the extension of alimony rights and obligations to cohabiting couples in brazil for women in intact relationships alimony rights upon dissolution should improve outside options strengthening their negotiating positions and increasing their influence over intrahousehold allocation of resources robust econometric evidence indicates that more decision power in the hands of women impacts hours worked by female adults and investments in the education of children this suggests that family policy and models of family decision making should take intrahousehold heterogeneity of preferences into account

explaining african economic performance africa has had slow growth and a massive exodus of capital in many respects it has been the most capital hostile region we review and interpret the aggregate level and microeconomic literatures to identify the key explanations for this performance there is a reasonable correspondence of the two sets of evidence pointing to four factors as being important these are a lack of openness to international trade a high risk environment a low level of social capital and poor infrastructure these problems are to a substantial extent attributable to government behaviour and the paper includes a review of the political economy literature which addresses that behaviour

female earnings and the divorce rate a simultaneous equations model economists have contributed a great deal of research both theoretical and empirical to the study of marital formation and dissolution many empirical examinations of marriage and divorce rates exist based on becker s seminal contributions to the literature all of these divorce studies are single equation models with female earnings assumed exogenous as discussed by becker 1981 however causality may run in the opposite direction as well the divorce rate may influence female earnings this paper estimates a simultaneous equations model in which divorce rates and female earnings are the jointly endogenous variables data are by state for 1960 1970 1980 and 1990 the state wide divorce rate equation is an extension of waters and ressler 1999 and the specification of a state wide earnings equation follows standard human capital theory the specification of joint endogeneity between female earnings and the divorce rate allows valid inferences to be made regarding the effect of female earnings on

why did child support award levels decline from 1978 to 1985 we use data from the panel study of income dynamics to examine trends in the receipt of child support and the determinants of trends between 1968 and 1997 the findings suggest that political demographic and economic forces all exerted downward

canadian contributions to family economics canadian scholars have made substantial contributions to the relatively new field of family economics these include new models of how men and women match in marriage markets and of how decisions are made in multi person households several were early contributors to the literature on married women s labour supply and labour supply in a family context and helped to develop empirical methods in this area a particular focus has been on the impacts of policy relevant parameters such childcare costs on family labour supply and child well being new work on child development the impact of early life conditions and the processes of intergenerational transmission also highlight the importance of family context in determining economic well being

marriage and divorce informational constraints and private contracting the relationship between divorce rates in the united states and laws regulating divorce are analyzed using data from a special current population survey undertaken in 1979 with particular reference to the adoption by many states of no fault divorce laws the author utilizes a contract theoretic framework to examine the impact of both legal and informational constraints on several aspects of the marriage relationship 1 the probability of divorce 2 compensation at divorce i e the terms of the divorce settlement 3 the probability of entering marriage and 4 incentives for investment in marriage specific capital two different models are developed the first assumes that ex post information about the value of each spouses opportunites at divorce is symmetric and that since divorce would only occur if the joint benefits outweigh the joint costs the law has no effect on the divorce rate the second model asserts that the existence of asymmetric information results in a fixed wage marriage contract and that divorce would be higher in states that allow unilateral divorce the evidence supports the first of these hypotheses excerpt

til death or taxes do us part the effect of income taxation on divorce there is now much empirical evidence that economic incentives affect the divorce decision via their impact on the flow of benefits of divorced vs married individuals however the effect of the individual income tax on divorce has been neglected in this work the income tax in the us is structured so that tax liability often changes with marriage some couples incur a marriage penalty in the form of higher taxes when they marry while others receive a marriage subsidy because their tax burden falls with marriage in this paper the authors examine the impact of the individual income tax on the likelihood of divorce in the us using data from the panel study on income dynamics they estimate a discrete time hazard model of the probability of divorce from the first marriage to test the hypothesis that the probability of divorce rises with the marriage penalty they also examine the role of other economic factors in the divorce decision the authors find that individuals respond to tax incentives in their decision to divorce although these responses are typically small and differ for men and women authors

endogeneity in semiparametric binary response models this paper develops and implements semiparametric methods for estimating binary response binary choice models with continuous endogenous regressors it extends existing results on semiparametric estimation in single index binary response models to the case of endogenous regressors it develops a control function approach to account for endogeneity in triangular and fully simulataneous binary response models the proposed estimation method is applied to estimate the income effect in a labor market participation problem using a large micro data set from the british fes the semiparametric estimator is found to perform well detecting a significant attenuation bias the proposed estimator is contrasted to the corresponding probit and linear probability specifications jel c14 c25 c35 j22

does child support enforcement reduce divorce rates a reexamination during the 1990s expenditures on child support enforcement increased dramatically as did the amount of money collected in these efforts this paper examines whether there is a link between the child support enforcement program and the divorce behavior of married couples with children previous work notably that of nixon 1997 found a significant negative effect of child support enforcement policy on the probability of divorce however using a panel of state divorce rates and policy variables i find that contrary to this previous study child support enforcement policy has no significant impact on divorce rates

unilateral divorce and the labor force participation rate of married women revisited two recent articles in this review by h elizabeth peters 1986 and william r johnson and jonathan skinner 1986 address an anomaly recently observed by labor economists james p smith and michael p ward 1985 have noted that real wage growth explains most of the increase in the female labor supply between 1950 and 1980 however in the period after 1970 the female labor supply growth rate rose while the real wage growth rate fell robert t michael 1985 provides a partial explanation by identifying the effect of divorce on the labor market decision of married women in that article a lagged relationship is observed between increases in the divorce rate and increases in the labor force participation rate lfpr of married women with young children during the post world war ii period since the divorce rate rose in the period after 1960 it could explain part of the increase in the growth rate of the lfpr of married women observed after 1970 the articles by peters and by johnson and skinner provide additional insights into this anomaly they recognize that the introduction of no fault grounds for divorce after 1970 may have contributed to the increase in the labor supply of married women after that date the no fault grounds for divorce created what has been called unilateral divorce the shift in female labor supply also could explain the slower real wage growth using 1979 data peters concludes that residence in a unilateral divorce state had a statistically significant positive influence on whether a married woman was in the labor force johnson and skinner use 1972 data to conclude that being in a unilateral divorce state in that year had a negative effect on the labor supply of married women unilateral divorce was introduced in the united states in 1970 when california adopted its no fault divorce statute therefore peters s data are probably more useful for testing the impact of unilateral divorce laws on married women s labor force participation in her article the lack of compensation for marriage specific investment at divorce creates an incentive for married women to increase their more general market capital during marriage by entering the labor force 2 a lack of compensation for marriage specific investment implies that women are not being compensated for being good housewives and mothers given the range of commodities produced by housewives and mothers marriage specific investment should not necessarily vary with characteristics of women such as age race or education if the impact of unilateral divorce on the lfpr of married women is due to the lack of compensation for mar regents professor of management robert 0 anderson schools of management university of new mexico albuquerque nm 87131 i thank michele blazek steve cauley dwight grant ron johnson rod lievano sam peltzman john schatzberg david weeks nelson woodard douglas young and two anonymous referees for their valuable comments the anderson schools of management provided research funding for this project ibefore 1970 most states had grounds for divorce that were based on fault such as adultery or mental cruelty between 1970 and 1985 all the american jurisdictions enacted some form of no fault divorce the no fault divorce statutes generally make either irretrievable breakdown or incompatibility the sole ground for divorce or add one of them to the fault grounds while no fault divorce is often called unilateral divorce that is not technically correct since some states require mutual consent to the no fault grounds see doris j freed and timothy b walker 1990 2while it was recognized by peters p 443 that women who invest in marriage may face lower wages in the future based on gary s becker 1981 p 15 marriage specific investment has value based on its ahilitv to increase houiehold nrodiution

finding missing markets and a disturbing epilogue evidence from an export crop adoption and marketing intervention in kenya in much of the developing world many farmers grow crops for local or personal consumption despite export options that appear to be more profitable thus many conjecture that one or several markets are missing this paper reports on a randomized controlled trial conducted by drumnet in kenya that attempts to help farmers adopt and market export crops drumnet provides smallholder farmers with information about how to switch to export crops makes in kind loans for the purchase of the agricultural inputs and provides marketing services by facilitating the transaction with exporters the experimental evaluation design randomly assigns pre existing farmer self help groups to one of three groups 1 a treatment group that receives all drumnet services 2 a treatment group that receives all drumnet services except credit or 3 a control group after one year drumnet services led to an increase in production of export oriented crops and lower marketing costs this translated into household income gains for new adopters however one year after the study ended the exporter refused to continue buying the cash crops from the farmers because the conditions of the farms did not satisfy european export requirements drumnet collapsed in this region as farmers were forced to sell to middlemen and defaulted on their loans the risk of such events may explain at least partly why many seemingly more profitable export crops are not adopted

linking smallholder farmers to markets on extensive and intensive margins evidence from nicaragua abstract access to modern commercialization channels is key for smallholder farmers to move away from subsistence farming and overcome poverty however achieving that goal is challenging for smallholders given their lack of appropriate managerial practices production technology and infrastructure this paper examines the association between receiving trainings in two distinct entrepreneurial practices one direct at the individual and farmer association level and another indirect at the community level and commercialization in non local markets at the extensive and intensive margins we exploit a panel dataset of bean producers in nicaragua that participated in an ngo program implemented between 2007 and 2012 we find opposite results for the two market linkage activities especially on the intensive margin or volume of sales while reciving direct training on entrepreneurial practices ep is positively associated with commercialization training on municipality engagement me activities is negatively associated these correlation patterns are mainly observed among entrant farmers as opposed to those already participating in commercial markets prior to the program implementation we also find varying results for me activities by plot size and leadership position additional estimations show that training activities that are positively correlated with bean commercialization are not necessarily correlated with the commercialization of other crops and vice versa

social assistance and conjugal union dissolution in canada a dynamic analysis using statistics canadas general social survey on family and friends carried out in 1990 we piece together the matrimonial and conjugal life history of a large sample of canadian men and women we then estimate duration models coxs proportional hazard models describing the evolutionary laws of marriages and unions which depend on various economic or socio demographic explanatory variables the empirical modelling focuses primarily on estimating the impact of couples earned incomes and of provincial welfare programs on the dissolution rate of first marriages and unions we find that welfare benefits do not have an impact on the hazard of union dissolution and that earned incomes have a positive effect on conjugal stability excerpt summary in fre

the effect of incomes wages and afdc benefits on marital disruption this paper uses a choice based model to estimate the effects of a broad set of economic factors including afdc benefit levels husband s earnings and a woman s wage rate on the probability of marital dissolution we find that the probability of divorce is lower for marriages in which the husband s labor income is higher we also find that while afdc income has a substantial effect on welfare receipt by a divorced woman it has a relatively small effect on the probability that a married woman will become divorced finally we find no support for the hypothesis that rising wages for women have increased marital instability

child support welfare dependency and poverty female headed families have among the highest poverty rates of any major demographic group in the united states the purpose of this paperis to investigate empirically the effectiveness of current child support enforcement policies and to determine their role in reducing poverty and welfare dependency a special supplement to the april 1982 current population survey provides the data for the analysis the results indicate that child support enforce ment may represent an effective means for re ducing welfare program costs but isunlikely to have a dramatic effect on either welfare de pendency or poverty copyright 1986 by american economic association

contracts hold up and exports textiles and opium in colonial india trade and export it is argued spur economic growth this paper studies the microeco nomics of exporting we build a heuristic model of transactions between exporters and producers and relate it to east india company operations in colonial bengal our model and the historical record stress two difficulties the exporter and its agents might not uphold payment agreements and producers might not honor sales contracts the model shows when procurement succeeds or fails highlighting the tension between these two hold up problems we analyze several cases including the east india company s cotton textile venture the famous opium monopoly and present day contract farming

the price effect of tariff liberalization measuring the impact on household welfare abstract trade policy literature has for many years emphasized open policies positive impact on economic growth and development while these results generally hold when measured on averages empirical evidence suggests that trade liberalization is unlikely to produce beneficial results across all households this study adds to the literature by providing an analysis of the distributive effects of tariff liberalization in mexico the paper examines the effect of tariff liberalization from the perspective of households both as consumers and factor owners allowing for imperfect domestic price transmission the results indicate the overall positive effect of tariff liberalization masks significant differences in the distribution of gains both across income levels and across geographic regions richer households are found to have gained relatively more urban areas as well as mexican states closest to the united states border are also found to be larger beneficiaries while southernmost states have been largely bypassed by the effects of tariff liberalization those results can be explained not only in relation to the different endowments of the households but also by the diverse effects on local prices that has resulted from mexican trade liberalization

should we write prenuptial contracts abstract a successful marriage requires for both parties to make investments in their relationship and marital assets how such assets would be divided if and when the parties divorce is an important factor determining each party s ex ante investment incentives using the incomplete contracting approach we characterize the optimal asset division rule one that provides the parties with the best investment incentives we then discuss the circumstances under which the spouses would agree in equilibrium to contract out state imposed rules governing the allocation of marital assets upon divorce we conclude by exploring the implications of our results in the context of various asset division rules currently discussed by policy makers

the economics of the marriage contract theories and evidence abstract we analyze the role of the marriage contract we first formalize three prominent hypotheses on why people marry marriage provides an exogenous payoff to married partners it serves as a commitment device and it serves as a signaling device for each theory we analyze how a reduction in the costs of divorce affects the propensity to divorce for couples at any given duration of marriage we then use individual marriage and divorce certificate data from the united states to bring these alternative views of the marriage contract to bear on the data we exploit variations in the timing of the adoption of unilateral divorce laws across states to proxy a one off and permanent reduction in divorce costs the results suggest that the dominant reason that couples enter into a marriage contract is that it serves as a commitment device

the economics of fatherhood the growth of nonmarital fertility together with greatly increased divorce rates and an increased proportion of children living in femaleheaded households has provoked considerable alarm about the demise of the traditional family and concern about potentially harmful effects on the well being of women and children in this paper i briefly summarize recent attempts by myself and others to develop a coherent theoretical framework to integrate economic theories of fertility and marriage in order to better understand why the same men who play the breadwinner role within marriage may fail to support their children following a divorce or who despite the gains to marriage may prefer to father children out of wedlock rather than within marriage i argue that such behaviors of men can be understood within a framework that takes into account the selfinterests of both men and women as they interact within a given sexual or marital match and as they interact in a broader market for sexual and marriage partners at the level of a given match the theory provides hypotheses about the determinants of voluntary child support by fathers who are divorced from or have never married the mother it also suggests reasons why voluntary child support is likely to be inadequate and consequently provides some insight about the role of laws and administrative procedures designed to establish paternity determine the size of childsupport awards and enforce collection of awards at the level of the market under certain circumstances theory produces results similar to those emphasized by william wilson and katherine neckerman s 1987 theory of outof wedlock childbearing among the underclass

ronald coase and methodology ronald coase wrote two great theoretical articles that earned him the nobel prize the nature of the firm in 1937 and the problem of social cost in 1960 he also wrote many articles dealing with the methodology of economics often in the setting of a discussion of a particular economist such as adam smith or alfred marshall the methodological articles will be my particular focus here

unilateral divorce versus child custody and child support in the u s this paper explores the response of the divorce rate to law reforms introducing unilateral divorce after controlling for law reforms concerning the aftermath of divorce which are omitted from most previous studies we introduce two main policy changes that have swept the us since the late 1970s the approval of the joint custody regime and the child support enforcement program because those reforms affect divorce decisions by counteracting the reallocation of property rights generated by the unilateral divorce procedure and by increasing the expected financial costs of divorce it is arguable that their omissions might obscure the impact of unilateral divorce reforms on divorce rates after allowing for changes in laws concerning the aftermath of divorce we find that the positive impact of unilateral divorce reforms on divorce rates does not vanish over time suggesting that the coase theorem may not apply to changes in divorce laws supplemental analysis developed to examine the frequency of permanent shocks in us divorce rates indicates that the positive permanent changes in divorce rates can be associated with the implementation of unilateral divorce reforms and that the negative permanent changes can be related to the law reforms concerning living arrangements in the aftermath of divorce this seems to confirm the important role of these policies in the evolution of divorce rates

marriage divorce and interstate risk sharing in this paper we study the importance of marriage for interstate risk sharing in the us we find that us federal states in which married couples account for a higher share of the population are less exposed to state specific output shocks thus in addition to improving the allocation of risk at the individual level marriage also has implications for risk sharing at the more aggregated state level quantitatively the impact of marriage on interstate risk sharing varies over divorce regimes

research on rural to urban migration in ldcs the confusion frontier and why we should pause to rethink afresh abstract over 12 years of intensive research in the field of rural to urban migration have left the field beset with loss of direction and some serious doubts as to 1 whether research has really provided practitioners with more specific means of intervention 2 proper understanding of such intervention its justification and results 3 the areas in which the marginal benefit of extra research amounts to zero 4 those areas in which some consensus has emerged 5 which problem areas and specific issues merit intensive migration research in the coming years and 6 whether or not the academic profession has based its migration research effort in the past decade on an inappropriate set of presuppositions or even worse on invalid postulates a few examples of confusion and or fallacies that render this list more concrete are presented in this paper these are drawn from the areas of migration and fertility migration and education migration and the distribution of income by size migration and urban unemployment migration and the politics of economics migration and policy measures this paper then makes a plea for a major re evaluation which could and should provide a turning point in academic work and institutional thought the emphasis is on reformulation of the policy related presumptions on which research has been based for the past dozen years rather than trying to reach a better understanding of the decision making process generating rural to urban migration and its sectoral and overall social implications so as to devise more effective measures to contain reverse it the starting point should be an effort to effectively manipulate the phenomenon so as to turn it into a vehicle of national development and personal betterment
