does money talk the effect of a monetary attribute on the marginal values in a choice experiment when designing choice experiments for nonmarket valuation the role of the price attribute is of major importance in the energy sector the uncertainty of future direction of changes in prices makes it difficult to include an adequate price vector in the design we separately investigate the implication of using price vectors with increases and decreases in tariffs from current levels on marginal value estimate from choice experiment data developed using prospect theory in addition we also analyse the effect of excluding the price vector on these marginal values by and large our results support the neoclassical theory as we find that the means of the conditional estimates of the marginal values of attributes are unaffected by the direction of the price change and from exclusion of the price attribute however the distributions show a larger spread of values when the choice experiment implies a tariff decrease which may have policy implications

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

disentangling the effects of policy and payment consequentiality and risk attitudes on stated preferences abstract incentivizing respondents to truthfully reveal their preferences in stated preference surveys requires that they believe their survey responses can influence decisions related to the outcome in question policy consequentiality and that they will have to bear their share of the coercive cost if the outcome is implemented payment consequentiality we investigate the effects of these two aspects of perceived consequentiality on stated preferences in a field survey concerning renewable energy development in poland we find that beliefs in policy and payment consequentiality strengthen the respondents interest in having the project implemented however policy consequentiality decreases and payment consequentiality increases their sensitivity to the project cost which respectively increases and decreases their willingness to pay for the project we conclude that the two aspects of consequentiality should be addressed separately additionally we inquire the theoretically speculated links between the respondents perceptions of policy and payment consequentiality and their risk attitudes and we find no significant relationship

public regulation of agricultural biotechnology field tests economic implications of alternative approaches federal oversight of agricultural biotechnology field testing is based on public concerns that unknown consequences could arise from such tests and that firms may not adequately consider the public consequences of their research and development activities in this paper four general types of ex ante and ex post approaches to manage public risks from field testing are explored the analysis shows that the approaches are least effective at facilitating the research process yet controlling public risks when the research firm is small in size and potential damages exceed the value of the firm

women s schooling home teaching and economic growth the hypothesis that increases in the schooling of women enhance the human capital of the next generation and thus make a unique contribution to economic growth is assessed on the basis of data describing green revolution india estimates are obtained that indicate that a component of the significant and positive relationship between maternal literacy and child schooling in the indian setting reflects the productivity effect of home teaching and that the existence of this effect combined with the increase in returns to schooling for men importantly underlies the expansion of female literary following the onset of the green revolution

measuring returns on investments in collectibles this paper considers the question of how to measure and interpret the financial return to investing in collectibles we review various methodologies for creating priced indexes and then discuss studies that explicitly calculate a rate of return to some set of collectibles while most collectibles appear to yield positive real returns the majority embody more risk and yield lower financial returns than stocks other characteristics of collectibles prices such as covariance with other asset prices are also examined

the boundaries of loss aversion abstract in this article the authors propose some psychological principles to describe the boundaries of loss aversion a key idea is that exchange goods that are given up as intended do not exhibit loss aversion for example the authors propose that money given up in purchases is not generally subject to loss aversion the results of several experiments provide preliminary support for the hypotheses the authors find that consistent with prospect theory loss aversion provides a complete account of risk aversion for risks with equal probability to win or lose the authors propose boundaries for this result and suggest further tests of the model

gain and loss of money in a choice experiment the impact of financial loss aversion and risk preferences on willingness to pay to avoid renewable energy externalities abstract we examine how the direction of price changes affects the value people place on avoiding renewable energy externalities in poland additionally we investigate the influence of individuals financial loss aversion and financial risk preferences on this valuation in our study we conduct a choice experiment survey in which respondents choices indicate the value they place on avoiding wind solar and biomass externalities we combine this survey with a financial lottery choice task that elicits the respondents risk preferences and degree of loss aversion in the choice experiment we use both increases and decreases in electricity bills to depict the uncertain effect of new sources of energy generation on the current price level this design allows us to investigate if obtained values are independent of the payment mechanism in the analyzed context our results indicate that marginal utility of money seems to be lower with a rebate on the energy bill than with a surcharge we find that financial risk preferences affect people s choices both in a case of a surcharge and a rebate while loss aversion for money affects them just in the case of a rebate loss aversion for money seems to not be present during a buying process the results indicate that the more risk seeking people are in a financial domain the more they are willing to pay for proposed changes in renewable energy development at the same time people who are more risk averse require less compensation before they accept externalities from renewable electricity production moreover a higher compensation is required by people who are more loss averse with regard to money

intrahousehold distribution and poverty evidence from cote d ivoire poverty measures often ignore the distribution of resources within families and the gains from joint consumption in this paper we estimate the allocation process and adult economies of scale in households from cote d ivoire using a collective model of household consumption identification relies on the observation of adult specific goods as in the rothbarth method and a joint estimation on couples and singles our results show that men and women s shares of total expenditure are of the same order of magnitude and children s shares are small scale economies are large and affect poverty measures

l etranger status property rights and investment incentives in cote d ivoire this study uses data from cote d ivoire to show that outsider households have relatively small land holdings and less complete rights over land than locals it then demonstrates a link between property rights and investment incentives by looking at the decision to leave land fallow outsiders fallow a smaller proportion of their land indicating that their farms are left uncultivated for shorter periods this is only partly explained by their incomplete property rights and relative land poverty these differences in investment patterns lead to lower yields per hectare jel o12 q15

bride price and fertility decisions evidence from rural senegal abstractthis paper provides evidence about the relationship between bride price payments and fertility decisions in senegal higher bride price payments reduce the fertility pressure for women with results being robust to confounding socio economic and contextual factors the fertility reducing impact is greater for women who are economically dependent on their husbands in polygamous households and for arranged marriages a lower bride price increases fertility pressure while in monogamous households and for non arranged marriages the bride price does not affect fertility as bride price payments have less power over economically independent women empowerment will give leeway to girls in traditional societies

new roles for marriage in urban africa kinship networks and the labor market in kenya abstract this paper explores new roles that traditionally rural kinship networks organized around the marriage institution might play in improving labor market outcomes in urban africa using new data from kisumu kenya and controlling for selection into marriage we find that marriage significantly increases employment levels and incomes in our sample of migrants at the same time marriage increases the remittances that migrants send to the extended family consistent with the view that the benefits of the network come with additional social obligations these obligations appear to be borne disproportionately by high ability individuals who consequently defer marriage the negative selection into marriage that we uncover has consequences for the future viability of the urban networks with implications for long term growth and distribution in this economy

bankruptcy and care choice this article considers the care choice of a potentially bankrupt injurer when care is pecuniary and the legal system is characterized by strict liability i show contrary to previous results that such an injurer may take too little or too much care and that neither injurer care nor victim welfare is necessarily increasing in injurer wealth when injurers behave optimally analysis of an expected cost function demonstrates that injurer expected costs are a concave and increasing function of injurer assets a result suggesting applications to the study of vertical relationships and markets for agents

credit markets in northern nigeria credit as insurance in a rural economy this article addresses the issues of imcomplete markets and imperfect information in the context of credit markets in rural northern nigeria in much recent theoretical literature the problems of moral hazard and adverse selection are assumed to be decisive for the organization of agrarian institutions in contrast it is found that in the four villages surveyed credit transactions take advantage of the free flow of information within rural communities information asymmetries between borrower and lender are unimportant and their institutional consequences the use of collateral and interlinked contracts are absent credit transactions play a direct role in pooling risk between households through the use of contracts in which the repayment owed by the borrower depends on the realization of random production shocks by both the borrower and the lender

the value of familiarity effects of knowledge and objective signals on willingness to pay for a public good we design and conduct a field experiment in which treated subjects receive a precise and objective signal regarding their knowledge about a public good before estimating their wtp for it we find that the causal effect of objective signals about the accuracy of a subject s knowledge for a public good can dramatically affect their valuation for it treatment caused a significant increase of 85 129 in wtp for well informed individuals we find no such effect for less informed subjects our results imply that wtp estimates for public goods are not only a function of true information states of the respondents but beliefs about those information states

environmental policy based on strict liability implications of uncertainty and bankruptcy a firm level model is developed to analyze the impacts of bankruptcy and uncertain firm wealth on incentives for safety under a strict liability rule future damages and wealth are uncertain and a firm s income earning activities that possibly create damages are incorporated into the model this analysis shows that firms do not always undertake more of a risky activity than is socially desirable for the extremely hazardous industry case larger firms always undertake less of a risky activity than smaller firms for the cyclical industry case larger firms do not always conduct less of a risky activity than smaller firms

marriage laws and growth in sub saharan africa many sub saharan african countries are extremely poor it has been argued that the marriage system in particular polygyny is one contributing factor to the lack of development in this region polygyny leads to low incentives to save depressing the capital stock and output enforcing monogamy might seem like an obvious solution however such a law will have winners and losers in this paper we investigate the transition from a polygynous to a monogamous steady state we find that the initial old men will be big losers the reason is that they had married many wives in anticipation of the brideprice that future daughters will fetch however due to the marriage reform the value of daughters depreciates rapidly as the brideprice changes from positive to negative this increases savings and thereby the aggregate capital stock the interest rate falls and the initial young suffer a loss in capital income thus all men alive during the reform period experience a loss in utility young women and all future generations will benefit however the future gains are not enough to compensate the losers this may explain why many african countries experience strong resistance to changing their marriage laws

gender differentials in farm productivity implications for household efficiency and agricultural policy abstract within many african households agricultural production is simultaneously carried out on many plots controlled by different members of the household detailed plot level agronomic data from burkina faso provides striking evidence of substantial inefficiencies in the allocation of factors of production across the plots controlled by different members of the household production function estimates imply that the value of household output could be increased by 10 15 by reallocating currently used factors of production across plots this finding contradicts standard models of agricultural households a richer model of behaviour which recognizes that the individuals who comprise a household compete as well as co operate has important implications for the structure of agricultural production and for the design of agricultural policy

male female differences in agricultural productivity methodological issues and empirical evidence abstract most estimates of male female differences in technical efficiency from production function studies show that male and female farmers are equally efficient farm managers controlling for levels of inputs and human capital there is some evidence however of allocative inefficiency within households marginal products of labor depend on the relative scarcities of labor and the gender division of labor in specific farming systems many of these studies however are methodologically flawed greater attention needs to be given to appropriate estimation methods endogenous input choice the use of headship as a stratifying variable and the implications of intrahousehold resource allocation

liability insurance under the negligence rule we analyze the e ciency properties of the negligence rule with liability insurance when the tort feasor s behavior is imperfectly observable both by the insurer and the court e ciency is shown to depend on the extent to which the evidence is informative on the evidentiary standard for nding negligence and on whether insurance contracts can condition directly on the same evidence as used by courts to assess behavior when evidence is not directly contractible the negligence rule with compensatory damages is generally ine cient

resource management and the mayor s guarantee in french water allocation this paper uses standard methods in stochastic calculus tomeasure the cost of the agency conflict that pits electedofficials of french municipalities against the communities theyrepresent in the management of the water supply under the frenchlegal code the municipalities are responsible for the watersupply and the elected officials are personally liable for anydamage due to negligence on their part uncertainty regardingexactly how negligence will be defined by the courts puts theelected officials in a precarious position by delegatingauthority to an oligopoly of private firms however electedofficials can eliminate their personal liability which istransferred to the delegated firm many studies argue thatdelegation locks communities into long term contracts that areagainst their better interests thus the agency conflict mayaffect the delegation decision to the detriment of the community to determine whether or not this is true it is necessary to knowthe economic cost of the mayor s personal liability

two moment decision models and expected utility maximization two moment decision models are consistent with expected utility maximization only if the choice set or the agent s preferences are restricted this paper identifies a restriction which is sufficient to ensure this consistency and confirms that it holds in many economic models the implications for economic analysis are then derived two different approaches to representing an agent s preferences over strategies yielding random payoffs are in wide use under the mean standard deviation ms approach the agent is assumed to rank the alternatives according to the value of some function defined over the first two moments of the random payoff while the expected utility eu criterion assumes that the expected value of some utility function defined over payoffs is used instead the fact that there are these two competing approaches has generated a considerable literature some authors are concerned with the advantages and disadvantages of each while others deal with conditions under which the potentially different approaches would yield the same results or at least approximately so space does not

the role of common law in environmental policy comment in a recent contribution to this journal fritz sillner 1994 provides a rather harsh critic of the working of common law in environmental policy and a strict recommendation to rely on statutory law only in this field in this comment i will argue that the distinction of the small versus the large number case which is central to his argument is an oversimplification and misleading moreover i will argue that judge made law does actually play an important role as part of an environmental policy mix s6llner s line of reasoning proceeds as follows if you take a look at the state of the environment in common law countries e g usa or great britain and compare them in this respect to civil law countries e g france or germany you will not find that the former have done better on that account as should be expected following the efficiency hypothesis of common law as proposed by posner 1986 priest 1977 and others a further look will show you that opposed to their naming common law does only play a minor role in the environmental policy of the common law countries this gives according to sallner a strong indication that the alleged tendency of common law towards efficiency does not hold in this particular case he provides two explanations for this finding

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

celestial marriage and earthly rents interests and the prohibition of polygamy abstract just prior to the civil war the u s government set out on a relentless campaign to eliminate polygamy within the mormon church this paper offers evidence that the political restrictions on the practice of polygamy were the result of rent seeking by potential beneficiaries of such laws the edmonds act of 1882 polygamy created benefits for women but reduced the welfare of most men in a time period when only adult males had the franchise

watta satta bride exchange and women s welfare in rural pakistan in a setting where husbands wield considerable coercive power forms of marriage should adapt to protect the interests of women and their families the authors study the pervasive marriage custom of watta satta in rural pakistan a bride exchange between families coupled with a mutual threat of retaliation they show that watta satta may be a mechanism to coordinate the actions of two sets of in laws each of whom wish to restrain their sons in law but who only have the ability to restrain their sons the authors empirical results support this view the likelihood of marital inefficiency as measured by estrangement domestic abuse and wife s mental health is significantly lower in watta satta arrangements as compared with conventional marriages but only after properly accounting for selection

strategic choices in polygamous households theory and evidence from senegal this paper proposes a strategic framework to account for fertility choices in polygamous households a theoretical model specifies the main drivers of fertility in the african context and describes how the fertility of one wife might impact the behavior of her co wives it generates predictions to test for strategic interactions exploiting original data from a household survey and the demographic and health surveys in senegal empirical tests show that children are strategic complements one wife raises her fertility in response to an increase by the other wife because children are the best claim to resources controlled by the husband this result is the first quantitative evidence of a reproductive rivalry between co wives it suggests that the sustained high level of fertility in africa does not merely reect women s lack of control over births as is often argued but also their incentives to have many children this paper also contributes to the literature on household behavior as one of the few attempts to open the black box of non nuclear families

estimating the elderly s returns on the farm evidence from cote d ivoire abstract it is often said that the elderly in rural developing countries are more valued by the members of the society one possible economic reason for the relative status of the elderly in rural areas is that they are likely to have accumulated substantial farm specific capital thus increasing the productivity of the farm this paper examines whether the elderly contribute to the agricultural profits of households in rural cote d ivoire in an uncertain environment we estimate the returns to having elders on the farm using panel data and find that farm specific experience mitigates the fall in profits in adverse environmental conditions particularly at the lower end of the profit distribution thereby contributing to reduce the variance of profits the results hold even after controlling for the level of household assets and household fixed effects and the presence of experienced female members

stated preferences for conservation policies under uncertainty insights on the effect of individuals risk attitudes in the environmental domain the outcome of a conservation policy is often subject to uncertainty in stated preference valuation it is increasingly recognised that uncertainty affects preferences for the outcomes of environmental policies however there is also agreement that the effect of uncertainty and people s attitudes towards risk need to be better understood to shed more light on the impact of risk we designed a discrete choice experiment to compare preferences for environmental outcomes under climate change across two split samples each sample was confronted with a scenario where results were presented as certain or uncertain but were otherwise associated with the same expected values we found significant differences between the certain and the uncertain treatment with uncertain outcomes being associated with more extreme utility levels and willingness to pay in absolute terms this finding was confirmed irrespective of whether gains or losses were considered and despite sensitivity to uncertainty specific to the socio demographic profile our results suggest that individuals are not risk neutral in the presence of uncertainty around environmental outcomes these findings are crucial to better understand stated preferences for conservation policies in risky contexts our results reinforce the idea that uncertainty should be explicitly incorporated in the design of stated preference studies to better inform policy

ex post liability for harm vs ex ante safety regulation substitutes or complements this paper concerns the regulation of hazardous economic activities economists have generally viewed ex ante regulations safety standards pigouvian fees that regulate an activity before an accident occurs as substitutes for ex post policies exposure to tort liability for correcting extemalities this paper shows that where there is uncertainty there are inefficiencies associated with the exclusive use of negligence liability and that ex ante regulation can correct the inefficiencies in such a case it is efficient to set the safety standard below the level of precaution that would be called for if the standard were used alone jel 619

neoclassical theory versus prospect theory evidence from the marketplace several experimental studies have provided evidence that suggest indifference curves have a kink around the current endowment level these results which clearly contradict closely held economic doctrines have led some influential commentators to call for an entirely new economic paradigm to displace conventional neoclassical theory e g prospect theory which invokes psychological effects this paper pits neoclassical theory against prospect theory by investigating data drawn from more than 375 subjects actively participating in a well functioning marketplace the pattern of results suggests that prospect theory adequately organizes behavior among inexperienced consumers but consumers with intense market experience behave largely in accordance with neoclassical predictions moreover the data are consistent with the notion that consumers learn to overcome the endowment effect in situations beyond specific problems they have previously encountered this transference of behavior across domains has important implications in both a positive and normative sense

optimal sharing of foodborne illness prevention between consumers and industry the effect of regulation and liability consumers and the food industry can both prevent foodborne illness two questions are explored what is the socially optimal level of preventative effort by each and can tort and regulatory instruments induce such behavior analysis is complicated by two aspects of food safety technology one party s effort can affect the marginal effectiveness of the other party s effort and damage functions can be nonconvex previous analysis of accidents under torts and regulation fails to consider these generalizations indeed results concerning the ability of tort and regulatory instruments to induce first best and second best behavior often contradict previous results in the literature

intertemporal substitution in labor supply evidence from micro data the sensitivity of the supply of labor to intertemporal variation in the wage is an important issue in macroeconomics the analysis of social security and pensions and the study of life cycle patterns of work this paper explores two approaches to the measurement of intertemporal substitution that have appeared in the literature the first approach is to use consumption to control for wealth and unobserved expectations about future wages in the labor supply equation the second approach is to estimate a first difference equation for hours in which labor supply from the previous period serves as a control for wealth and wage expectations the results indicate that intertemporal substitution elasticity for married men is positive but small

strict liability as a deterrent in toxic waste management empirical evidence from accident and spill data abstract this paper examines whether strict liability imposed on polluters has reduced uncontrolled releases of toxics into the environment we fit regressions relating spills of selected chemicals to the type of liability in force in a state and to state manufacturing activity for some chemicals spills are more numerous in states imposing strict liability this could be due to unobserved state characteristics with small firms being responsible for a disproportionate number of spills regardless of the liability structure alternatively separate regressions for the two liability regimes suggest that only under strict liability are small firms responsible for a disproportionate number of spills

gender agricultural production and the theory of the household virtually all models of the household assume that the allocation of resources is pareto efficient within many african households agricultural production occurs on many plots controlled by different members of the household pareto efficiency implies that factors should be allocated efficiently across these plots i find in contrast that plots controlled by women are farmed much less intensively than similar plots within the household controlled by men the estimates imply that about 6 percent of output is lost because of inefficient factor allocation within the household the paper suggests a new approach to modeling intrahousehold allocation consistent with the empirical results

a flexible assurance bonding system for improved environmental management abstract current methods of regulating activities that are known or suspected to be environmentally danaging are not working well they induce legal confrontation obfuscation and government intrusion into the inner workings of firms they tend to suppress technical and social innovation aimed at long term solutions they do not mesh well with the market signals that firms use to make decisions this paper discusses some of the underlying reasons for this problem and outlines a flexible environmental assurance bonding system designed to incorporate environmental criteria and uncertainty into the market system and to induce positive environmental technological innovation in addition to direct charges for known environmental damages an assurance bond equal to the current best estimate of the largest potential future environmental damages would be levied and kept in an interest bearing escrow account the bond plus a portion of the interest would be returned if and only if the firm could prove that the suspected damages had not occured or would not occur if damages did occur the bond would be used to rehabilitate or repair the environment and to compensate injured parties by requiring the users of environmental resources to post a bond adequate to cover potential future environmental damages with the possibility for refunds the burden of proof is shifted from the public to the resource user and a strong economic incentive is provided to research the true costs of environmentally innovative activities and to develop innovative cost effective pollution control technologies

liability and large scale long term hazards this paper analyzes the application of liability to large scale long term hazards the key features distinguishing such hazards are the long temporal separation between exposure to a hazard and disease and the large damages when injuries finally emerge the large scale of damages creates a strong incentive to avoid liability payments and the long temporal separation creates numerous avenues through which parties can avoid paying possible damage awards the analysis focuses on the incentive to avoid paying damages by vertically divesting production tasks associated with serious occupational risks such divestiture can lower liability costs if the small firm operating the risky stage goes out of business before latent injuries emerge or has insufficient assets to pay damages and declares bankruptcy when suits are filed the paper then presents an empirical regression analysis of small firm entry into the u s economy between 1967 and 1980 the period in which liability laws were changing the point estima

the effects of experience on preferences theory and empirics for environmental public goods this article develops a choice model for environmental public goods which allows for consumers to learn about their preferences through consumption experiences we develop a theoretical model of bayesian updating perform comparative statics over the model and show how the theoretical model can be consistently incorporated into a reduced form econometric model our main findings are that in a random utility model rum discrete choice model a subject s scale should increase and the variability of scale should decrease with experience if subjects are bayesians we then estimate the model using field data regarding preferences for one particular public good water quality we find strong evidence that additional experience increases scale thereby making consumer preferences more predictable from the econometrician s perspective we find supportive but less convincing evidence that experience decreases the variability of scale across subjects

time to change what to sow risk preferences and technology adoption decisions of cotton farmers in china this paper examines the role of individual risk attitudes in the decision to adopt a new form of agricultural biotechnology in china i conducted a survey and a field experiment to elicit the risk preferences of chinese farmers who faced the decision of whether to adopt genetically modified bt cotton a decade ago in my analysis i expand the measurement of risk preferences beyond expected utility theory to incorporate prospect theory i find that farmers who are more risk averse or more loss averse adopt bt cotton later farmers who overweight small probabilities adopt bt cotton earlier

developments in non expected utility theory the hunt for a descriptive theory of choice under risk this article reviews recent developments in the economic theory of individual decision making under risk since the 1950s it has been known that individual choices violate the standard model of expected utility in predictable ways considerable research effort has now been devoted to the project of developing a superior descriptive model following an overview of non expected utility theories which distinguishes between conventional and non conventional approaches the paper seeks to assess these alternative models in terms of empirical success using laboratory and field data and theoretical usefulness the closing sections reflect on some new directions emerging in this literature

the mystery of monogamy we examine why developed societies are monogamous while rich men through out history have typically practiced polygyny wealth inequality naturally pro duces multiple wives for rich men in a standard model of the marriage market however we demonstrate that higher female inequality in the marriage market reduces polygyny moreover we show that female inequality increases in the process of development as women are valued more for the quality of their chil dren than for the quantity consequently male inequality generates inequality in the number of wives per man in traditional societies but manifests itself as inequality in the quality of wives in developed societies jel j12 j16 j24 z13

on the timing of marriage cattle and weather shocks abstractin this paper we focus on the timing of marriage of women whose marriages are associated with bride wealth payments these payments concern transfers from the family of the groom to the bride s family unmarried daughters could therefore be considered part of the asset portfolio of the household that at times of need can be cashed we investigate both theoretically and empirically to what extent the timing of marriage of a daughter is affected by the economic conditions of the household from which she originates we distinguish household specific wealth levels and two types of shocks correlated weather shocks and idiosyncratic wealth shocks we estimate a duration model using a unique panel survey of zimbabwean smallholder farmers the estimation results support the hypothesis that the timing of marriage is affected by household characteristics girls from households that experienced a negative idiosyncratic wealth shock are more likely to marry

lifestyles of the rich and polygynous in cote d ivoire abstract this paper investigates whether the sources of income not just the levels determine whether an individual is monogamous our results support the idea that polygyny stunts development by allowing wealthy men to acquire wives rather than investing in child quality

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

data watch the world bank s living standards measurement study household surveys since 1985 the world bank has been collecting household survey data in developing countries that provide a rich source of information for assessing household welfare understanding household behavior and evaluating the impact of government policies this article describes these household surveys known as living standards measurement study lsms surveys and explains how to obtain their data lsms surveys have been implemented in over twenty developing countries and have been used to analyze poverty labor markets health and education pricing policies determinants of school performance savings and consumption smoothing health and nutrition policies and gender and fertility issues

is risk fully pooled within the household evidence from ghana using detailed household survey data from ghana this paper examines whether the transitory incomes of individual household members affect household expenditure patterns divided into six sections the themes include risk sharing networks household survey data from ghana theoretical framework of risk sharing within households estimating transitory income and effects on household budget shares the conclusion that transitory incomes earned by different members of the household have different effects on household expenditure patterns this implies that household members do not engage in full risk pooling with each other moreover it is not always the case that all women or all men display similar preferences or risk pooling behavior this suggests complex features within the household risk sharing structure which is more complex than might be hypothesized by a simplistic analysis framed along gender lines

the economics of dowry and brideprice payments between families at the time of marriage existed during the history of most developed countries and are currently pervasive in many areas of the developing world these payments can be substantial enough to affect the welfare of women and a society s distribution of wealth recent estimates document transfers per marriage amounting to six times the annual household income in south asia rao 1993 and four times in sub saharan africa dekker and hoogeveen 2002 this paper first establishes some basic facts about the prevalence and magnitude of marriage payments it then discusses how such patterns vary across countries depending upon economic conditions societal structures institutions and family characteristics such payments have also evolved within societies over time for example in some periods such payments have risen sharply in some cases payments have shifted from the grooms sides to the brides and vice versa also property rights over such payments have sometimes shifted between marrying partners and parental generations economists who have only recently begun to work on the topic have focused on explaining these facts the second part of the paper addresses this economic literature though considerable insight into many of the facts has been gained many of the existing economic explanations are weakly convincing and many puzzles remain one crucial difficulty is that solid data in this field have been extremely rare the descriptions of marriage payments in this paper are synthesized from a patchwork of studies across periods places and even epochs and there are doubtless numerous cases which remain undocumented thus the paper

altruism cooperation and efficiency agricultural production in polygynous households abstractaltruism toward others can inhibit cooperation by increasing the utility players expect to receive in a noncooperative equilibrium to test this we examine agricultural productivity in west african polygynous households we find cooperation as evidenced by more efficient production is greater among co wives than among husbands and wives using a game theoretic model we show that this outcome can arise because co wives are less altruistic toward each other than toward their husbands we present a variety of robustness checks which suggest results are not driven by selection into polygyny greater propensity for cooperation among women or household heads enforcing others cooperative agreements

indivisible toxic torts the economics of joint and several liability cost effective or efficient pollution control has traditionally devoted most of its attention to analyzing the effects of legislative or regulatory policy instruments such as emission taxes or marketable emission permits recent contributions have expanded this focus to include the effects of monitoring and enforcement policies 2 with a few noteworthy exceptions 3 however the role of the court system in general and liability law in particular have not received analytical attention among environmental economists in proportion to their importance in resource allocation

bad eggs learning by doing and the choice of technology we model long run economic development through technology adoption under scientific uncertainty about environmental effects there are four possible long run equilibria in a socially planned economy high growth adopt rapidly but abandon damaging technologies once revealed ddt cfcs cautious brake the introduction of new technologies to avoid mistakes genetically modified organisms no growth halt technological progress to preserve secondary knowledge and collapse adopt rapidly without ever abandoning damaging technologies in the base parameterization a short sighted social planner chooses the cautious strategy a far sighted planner chooses the high growth strategy unless damages are irreversible in which case the cautious strategy again dominates regulatory options in the market economy are investigated pollution taxes do not affect the firm s level of precaution if they can only be applied after the adopting firm has reaped the benefits however they do encourage the abandonment of damaging technologies liability rules do affect precaution but may lead to excessive caution or even a no growth trap

demand for insurance and within kin group marriages evidence from a west african country abstract we ask whether parents have incentives to marry their children to a member of the kin group in order to better insure against adverse idiosyncratic income shocks exploiting original panel data from a household survey collected in senegal in 2006 2007 and 2011 2012 we find that daughters within kin group marriage helps their parents household to better smooth food consumption when a parent has fallen ill this better smoothing is notably driven by the fact that households having married a daughter within the kin group receive relatively more transfers our results indicate that parents demand for insurance can explain part of their demand for marrying within the kin group their daughter and extend the literature on inter linkages between marriage decisions and demand for insurance

the risk of polygamy and wives saving behavior in a polygamous society all monogamous women are potentially at risk of polygamy however the anthropological and economic literatures are silent on the potential impact of the risk of polygamy on the economic decisions of monogamous wives this paper explores this issue in senegal using individual panel data the paper first estimates a cox model for the probability of transition to polygamy second it estimates the impact of the predicted risk of polygamy on monogamous wives savings the findings show a positive impact of the risk of polygamy on female savings entrusted to formal or informal institutions which is suggestive of self protective strategies the increase in savings comes at the cost of reduced consumption of household food expenditures and wives private nonfood expenses
