the multifaceted role of the state in the protection of geographical indications a worldwide review summary geographical indications gis serve to designate goods with a quality characteristics or reputation attributed to its geographical origin they are increasingly protected in many countries of the south as a tool for economic social territorial and ecological development implemented in the wake of the weakly prescriptive wto agreement on trade related intellectual property rights trips of 1995 the choice of the institutional framework for protecting gis nationally as well as associated public support infrastructure was left open this led to divergences in overarching approaches and to gi institutionalization that differs remarkably across countries twenty years after trips the purpose of both this paper and of the special issue is to advance our understanding of the institutionalization of gis as an ipr a quality standard and a policy instrument in harnessing all of the expected benefits of gi protection building upon the contributions to this special issue we use an original multilevel governance framework to analyze all the multifaceted roles of the state in different empirical situations worldwide this reflects the experiences of countries that have only recently implemented gi protection such as brazil colombia india indonesia vietnam south africa kenya and west african countries as well as of regions with a long history of gi protection including the eu and the us based on an analysis of the complexity and diversity of all state we show that global harmonization is underway with a convergence toward a prominent role of the state in gi regulation in particular for defining gi content which is specific for gis when compared to other iprs or quality standards we suggest that the intervention of the state is supported by a universal desire to guard against unfair exclusion and to protect a common heritage

long term competition in a dynamic game the cold fish war this article presents a model of credible voluntary collective agreements in a dynamic game these agreements are implicit in collections of history dependent threat strategies i consider the strategies in a game of resource exploitation credibility is represented by perfect equilibrium voluntarism requires at least that all behavior be supported by the threat of collapse of the agreement which would return the players to the memoryless equilibrium collective rationality requires that the agreement be robust to the possibility of mutually beneficial renegotiation i analyze the set of agreements meeting each of these restrictions

children as collective goods and divorce settlements the failure of many divorced fathers to comply with court mandated child support awards has been identified as a major reason why a growing number of children live in poverty in female headed households this paper presents a model that seeks to explain why so many divorced fathers allow their children s welfare to suffer as a consequence of divorce the point of departure is the recognition that children are collective consumption goods from the point of view of the father and mother within marriage proximity and altruism serve to overcome the free rider problem associated with the provision of public goods however on divorce the noncustodial parent suffers a loss of control over the allocative decisions of the custodial parent and it is not feasible for the couple to achieve a pareto optimal allocation of their joint resources a model of optimal marriage contracts is constructed in which a couple decides on the allocation of resources within marriage and on the terms of a settlement in the event

female labour supply and marital status decisions a life cycle model this paper studies the interdependence between and the determinants of life cycle marital status and labour force participation decisions of women a dynamic utility maximization model is presented and estimated using longitudinal data on women from the panel study of income dynamics the mle method employed involves solving a dynamic programming problem further a minimum distance estimator is proposed which allows for the incorporation of wage data in a computationally simple way the estimates are used to predict changes in the life cycle patterns of employment marriage and divorce due to differences in education race the female s earnings and her potential husband s earnings the estimation results indicate that the utility gains to marriage are decreasing in the female s wage rate and increasing in her potential husband s earnings while the opposite is found for gains to working ignoring the endogeneity of marital status decisions is shown to lead to an underestimation of own and husband s wage effects on female labour supply

a diamond is forever and other fairy tales the relationship between wedding expenses and marriage duration in this study we evaluate the association between wedding spending and marriage duration using data from a survey of more than 3 000 ever married persons in the united states controlling for a number of demographic and relationship characteristics we find evidence that marriage duration is inversely associated with spending on the engagement ring and wedding ceremony jel j12 z1 d1

a reanalyis of marital stability in the seattle denver income maintenance experiment this paper challenges the widely cited finding of groeneveld hannan and tuma that the seattle denver income maintenance experiment provides evidence that guaranteed income plans for poor husband wife families will increase marital dissolution relative to the existing program aid to families with dependent children the reanalysis of the experimental data distinguishes between the experimental treatment in the form of the pure negative income tax and the treatment plans that involved an experimental training program all the time periods of the experiment are used with allowance for the timing of the marital dissolution in the inferences and with allowance for attrition the conclusion of this paper is that the plans specifically the negative income tax plans in the experiment had no effect on the rate of marital dissolutions among the treatment couples relative to the control couples

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

the economics of urban sprawl theory and evidence on the spatial sizes of cities many commentators believe that the phenomenon of urban sprawl which is characterized by vigorous spatial expansion of urban areas is a symptom of an economic system gone awry by transforming pastoral farmland into often unattractive suburbs sprawl is thought to disrupt a natural balance between urban and non urban land uses leading to a deplorable degradation of the landscape this sentiment is often translated into policy through zoning restrictions designed to inhibit the conversion of land from agricultural to urban use see bryant and conklin 1975 the economist s view of urban expansion stands in stark contrast to this emotionally charged indictment of sprawl economists believe that urban spatial size is determined by an orderly market process which correctly allocates land between urban and agricultural uses the model underlying this view which was originally developed by muth 1969 and mills 1972 and more completely analyzed by wheaton 1974 suggests that urban spatial size is determined in a straightforward way by a number of exogenous variables by showing empirically that urban size is related to the given variables population income agricultural rent and commuting cost in the manner predicted by the model the present paper achieves two goals first the empirical results suggest that the economist s view of urban sprawl is justified rather than being determined by a process which indiscriminately consumes agricultural land urban sizes are the result of an orderly market equilibrium where competing claims to the land are appropriately balanced 2 second by confirming the urban size predictions of the underlying model the empirical results constitute yet another piece of evidence validating the basic framework of urban economic analysis 3 the plan of the paper is as follows section ii sketches the structure of the muth mills model and presents the main comparative static results relevant to urban sprawl with the model s predictions in focus section iii discusses the sample and the data and section iv presents the empirical results section v offers conclusions

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

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

a latent structure approach to measuring reputation the present study provides estimates of reputation as a dynamic latent variable that is determined by price premiums and market data further it analyzes the effect of extrinsic factors on reputation specifically this study seeks to i quantify the reputation of washington apples over time ii study the dynamic nature of reputation and iii analyze the effect of the label washington apple the model adopted in this study is the dynamic multiple indicator multiple cause dymimic modeling approach which is a special case of the general latent variable modeling scheme called state space models both dymimic and hedonic approaches are applied to the data on washington apples and results from the two approaches are compared reputation plays an important role in assuring product quality in markets where consumers can only imperfectly judge the product quality until after consumption if reputation effects are absent in these types of markets there is an incentive for producers to reduce quality and take short run gains before buyers catch on in order to avoid such quality cutting products with good reputations will sell for premium prices shapiro 1983 showed theoretically that price premiums are necessary for producers to invest in quality and reputation there is an extensive theoretical literature on reputation but empirical studies are limited empirical studies on the impact of firm reputation on shareholder wealth or product demand include jarrell and peltzman 1985 borenstein and zimmerman 1988 and karpoff and lott 1993 caves and green 1996 showed that factors that may affect a firm s reputation influence the relationship between price and quality gorton 1996 analyzed how a bank s reputation for default affects the discount rate on its debt the measurement of the value of reputation to producers in terms of price premiums and how a reputation can be built up and destroyed are important issues that have not been empirically analyzed the current study provides estimates of reputation as a dynamic latent variable that is determined by price premiums and market data further it analyzes the effect of extrinsic factors on reputation steenkamp 1990 points out that consumers observe at the moment of purchase the intrinsic and extrinsic product quality cues but not the quality attributes intrinsic cues are characteristics of the product such as color freshness texture and flavor while extrinsic

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

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

monopolistic competition with experience goods this paper constructs a model of monopolistic competition where consumers cannot directly verify product quality prior to an initial purchase instead consumers base initial purchases on observed prices which perfectly signal firms qualities both in and out of equilibrium equilibrium quality is less than efficient but generally bounded away from the minimum quality with free entry observable product variety exceeds what would prevail with perfect information as repeat purchases become large relative to initial purchases or as firms become small relative to the size of the market equilibrium product quality rises and the market converges to the full information equilibrium

female income and the divorce decision evidence from micro data escalating divorce rates during the 1960s and 1970s led to large numbers of academic investigations into the causes of divorce most of these studies concentrated on a significant increase in female income that resulted from rising female labour force participation rates the difficulty with quantifying these arguments is that it is possible to observe the income of married females or it is possible to observe the income of divorced females but it is not possible to observe both outcomes simultaneously this research attempts to resolve these difficulties by using sample selection techniques to correct for possible bias from simple observation of the income of married and divorced females

a theory of collective reputations with applications to the persistence of corruption and to firm quality the paper is a first attempt at modelling the idea of group reputation as an aggregate of individual reputations a member s current incentives are affected by his past behaviour and because his track record is observed only with noise by the group s past behaviour as well the paper thus studies the joint dynamics of individual and collective reputations and derives the existence of stereotypes from history dependence rather than from a multiplicity of equilibria or from the existence of a common trait as is usually done in the literature it shows that new members of an organization may suffer from an original sin of their elders long after the latter are gone and it derives necessary and sufficient conditions under which group reputations can be rebuilt last the paper applies the theory to analyse when a large firm can maintain a reputation for quality 1 collective reputations collective reputations play an important role in economics and the social sciences countries ethnic racial or religious groups are known to be hard working honest corrupt hospitable or belligerent some firms enjoy substantial rents from their reputations for producing high quality products some departments are reported to treat their faculty or students fairly the paper is a first attempt at modelling the idea of group reputation as an aggregate of individual reputations a member s current incentives are affected by her past behaviour and because her track record is observed only with noise by the group s past behaviour as well the paper studies the joint dynamics of individual and collective reputations in a model in which current generations are progressively replaced by new ones and derives the existence of stereotypes from history dependence rather than from a multiplicity of equilibria or from the existence of a common trait as is usually done in the literature see section 2 for a detailed comparison with the literature it shows that new members of an organization may suffer from an original sin of their elders long after the latter are gone and it derives necessary and sufficient conditions under which group reputations can be rebuilt last the paper applies the theory to analyse when a large firm can maintain a reputation for quality let us spell out the building blocks of our theory in more detail a a group s reputation is only as good as that of its members each member is characterized by individual traits such as talent diligence or honesty past individual behaviour conveys information about these traits and generates individual reputations

reputation and imperfect information abstract a common observation in the informal literature of economics and elsewhere is that is multistage games players may seek early in the game to acquire a reputation for being tough or benevolent or something else but this phenomenon is not observed in some formal game theoretic analyses of finite games such as selten s finitely repeated chain store game or in the finitely repeated prisoners dilemma we reexamine selten s model adding to it a small amount of imperfect or incomplete information about players payoffs and we find that this addition is sufficient to give rise to the reputation effect that one intuitively expects

the excess sensitivity of layoffs and quits to demand excessive layoffs in bad times and excessive quits in good times both stem from the same weakness in practical employment arrangements the specific nature of worker firm relations creates a situat

a game theoretic approach to behavioral food risks the case of grain producers abstract food risks may be caused by malpractice of suppliers who exploit the fact that their production processes and resulting product properties cannot be directly observed by buyers the probability of malpractice increases with the profits that can be earned through opportunistic behavior in this paper we develop a moral hazard model for the empirical analyses of behavioral risks it accounts for the essential fact that incomplete inspection and tracing increase the profitability of rule breaking behavior and that monitoring tracing and sanctioning are costly using the model we first demonstrate how to design efficient contracts in various situations in a case study we then analyze farmers incentives with regard to the minimum waiting period after fungicide use data are gathered in interviews with three large scale german farmers and a grain dealer we find that while their perception of parameters varies widely high temptations for rule breaking arise in some cases we conclude that empirical moral hazard analyses have significant potential to shed light on behavioral risks

work and welfare as determinants of female poverty and household headship this paper formulates and estimates a model of the determinants of female household headship headship responds to variations in the levels of well being a woman can expect if she marries or if she heads her own household the authors measure the opportunity cost of female headship and the effects of welfare benefits and womens work in the market on female headship and poverty they find that if welfare benefits were reduced there would be small reductions in the proportion of women heading households for whites and nonwhites but a substantial increase in poverty for nonwhites they also find that wives work in the market reduces poverty and female headship for nonwhites and reduces poverty but increases headship for whites the study is based on 1975 u s data excerpt

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

collective reputation and quality firms who sell regional or specialty products often share a collective reputation based on aggregate quality collective reputation can be approached as a dynamic common property resource problem we show that for an experience good without firm traceability individual firms have the incentive to choose quality levels that are sub optimal for the group these results support minimum quality standards trigger strategies are analyzed as an alternative solution to this problem finally the implications of these results are discussed as they relate to the case study of washington apples specialty regional authentic and local food products have become a more important part of consumer purchases in recent years firms have responded by marketing food products that come from specific geographic areas this trend in consumers preferences has led the european union to introduce protected designations of origin labels and protected geographical identification labels which provide protection of food names on a geographical or traditional basis ranging from parmesan cheese to such lesser known items such as galician veal in the united states there are popular state products that carry labels such as washington apples idaho potatoes

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

clearing the air in atlanta transit and smart growth or conventional economics abstract the atlanta s regional transportation plan addresses the problems of pollution and congestion by proposing to expand the existing transit network and to promote a more intensive use of the existing built up area this paper argues that neither of these proposals is feasible the current spatial structure of atlanta is incompatible with a sizable transit market share and atlanta s spatial structure cannot be changed significantly in the next 20 years even if draconian land use regulations were adopted as a result technology and congestion pricing are the only way to solve the problems of pollution and congestion in atlanta

the economics of grief we study the short run and long run economic impact of one of the largest losses that an individual can face the death of a child we utilise unique registers on the entire swedish population combining information on the date and cause of death with parental outcomes we exploit the longitudinal dimension of the data and deal with several selection issues losing a child has adverse effects on labour income employment status marital status and hospitalisation the value of policy measures aimed at preventing mortal accidents of children is underestimated if it does not take bereavement effects on parents into account

the economics of collective reputation evidence from the wine industry we use original data regarding the array of italian winery coalitions wine denominations to analyze the economics and determinants of collective reputation we first run a cross sectional analysis with 2008 data and the full set of control variables then move to the dynamics of collective reputation with panel data analysis on a 30 year time span 1978 2008 group reputation is history dependent in particular past bad collective behavior increases the probability of being stuck in a bad reputation trap minimum quality standards and effective enforcement are fundamental drivers of group reputation the relationship between group size and collective reputation is non linear free entry may not be optimal due to free riding problems finally institutional signals such as the wine classification system are useful because they can be used by consumers as easily available proxies for information that is much more difficult to acquire

child support and partnership dissolution this article studies the determinants of partnership dissolution and focuses on the role of child support we exploit the variation in child support liabilities and entitlements driven in part by the introduction of a new set of complex rules that determined child support liability in the uk and by their interaction with welfare rules our panel has the virtue that the post 1993 variation in child support liability for all couples in partnerships formed prior to 1993 is unanticipated we find strong evidence that the resulting large child support liabilities significantly reduced dissolution risks

on the social desirability of urban rail transit systems despite a decline in its mode share investment to build new urban rail transit systems and extend old ones continues we estimate the contribution of each u s urban rail operation to social welfare based on the demand for and cost of its service we find that with the exception of bart in the san francisco bay area every system actually reduces welfare and is unable to become socially desirable even with optimal pricing or physical restructuring of its network we conclude rail s social cost is unlikely to abate because it enjoys powerful political support from planners civic boosters and policymakers

markets with untraceable goods of unknown quality beyond the small country case when importing durables and nondurables consumers often cannot discern quality prior to purchase if they cannot also identify the individual producer exporters have diminished incentives to produce high quality goods to raise the quality of traded experience goods previous international literature has proposed consolidation of export firms and the imposition of export quotas policies that may be appropriate for tiny taiwan but not a colossus like china we contribute to this literature in three ways first we explicitly model the way in which consumers of experience goods rely on the reviews of previous buyers who in turn rely on the reviews of buyers before them when deciding whether to purchase an experience good second we endogenize the price of any given quality third we assume that firms may exercise market power as we show once the small country assumption is dropped policies advocated in the literature such as the merger of exporters or the imposition of export quotas can have adverse consequences on the profits of domestic exporters and on the welfare of all consumers on the other hand the unilateral imposition of minimum quality standards will increase the profits of domestic exporters while improving the welfare of all consumers

sparkling wine choice from supermarket shelves the impact of certification of origin and production practices we report the results of a study based on revealed and stated preference data on choice of prosecco wines in retail stores close to the origin of production in northern italy emphasis is placed on ability to reconcile the utility structure of stated preference data with that underlying revealed preference data we extend the analysis to cover nonattendance of key attributes such as price and certification of origin while controlling for the large range of brand effects

social welfare in a common property oligopoly output in a markov nash cournot equilibrium to a noncooperative differential game in which in oligopolists extract a common property nonrenewable resource is bounded by the output of in firm and in i firm static oligopolies we discuss the welfare effects of the number of firms and of the divergence between private and social discount rates we compare extraction under the markov and open loop equilibria and then offer an explanation for the possibility that the resource is exhausted instantaneously in a continuous time game this explanation does not depend on the fact that the period of commitment is infinitesimal this essay models the extraction by an oligopolistic industry of a common property nonrenewable resource we characterize the markov perfect equilibrium mpe in a game amongst firms and then provide general conditions under which the resource is exhausted instantaneously if there is unrestricted access to a resource agents perceive its shadow value to be 0 and extract too rapidly when access is restricted to a finite number of agents in none of whom possess exclusive property rights an additional complication may arise if firms behave as oligopolists in the product market they have an incentive to extract the resource too slowly in order to increase the price thus where m firms exploit a resource in the absence of property rights there are conflicting tendencies the absence of property rights encourages excessive exploitation whereas the finite number of firms encourages insufficiently rapid exploitation there are a number of situations where the lack of property rights and the presence of market power coexist examples include i national fisheries which are large enough to affect fish populations and output prices ii common exploitation of aquifers or rivers where individual use affects the price of an agricultural output or of another input iii production by oligopolistic firms which degrades the environment we consider the case of nonrenewable resources such as oil this implies a simple equation of motion for the stock of the resource and emphasizes the role of the number of firms and the stock size such models are often appropriate even if the resource is not literally nonrenewable for example tropical forests or groundwater aquifers are potentially renewable given enough time as indeed oil deposits may be however the rate of replenishment may be insignificant given

demand for collective food safety standards in 2007 leading members of the u s fresh tomato industry responded to pressure from the u s food and drug administration regarding the industry s long history of poor food safety outcomes and adopted a set of standards for production practices related to food safety at all levels of the fresh tomato supply chain adherence to these standards was required under a federal marketing order that applied to essentially all tomatoes grown in florida the california tomato farmers cooperative whose members produced the vast majority of fresh tomatoes grown in california also required that its members adopt these standards the collective food safety standards for fresh tomatoes closely resemble the requirements of the u s food safety modernization act fsma produce safety rule so the collective adoption of these standards provides an excellent case study to illustrate the possible effects of fsma implementation on demand i assess the hypothesis that demand for tomatoes from florida and california increased following the adoption of standards for food safety practices by growers in those states relative to demand for tomatoes from other regions my analysis demonstrates essentially no evidence that demand for fresh tomatoes responded positively to the implementation of collective food safety practices

lucky in life unlucky in love the effect of random income shocks on marriage and divorce abstract economists have long been interested in the extent to which economic resources affect decisions to marry and divorce however this issue has been difficult to address empirically due to a lack of exogenous income shocks we overcome this problem by exploiting the randomness of the florida lottery and comparing recipients of large prizes to those of small prizes results indicate that while positive income shocks of 25 000 to 50 000 do not cause statistically significant or economically meaningful changes in divorce rates single women are less likely to marry as a result of the additional income

household finances income shocks and family separation in britain we examine the effect of household financial indebtedness on the incidence of partnership dissolution using a large survey of families with children in britain we use detailed data on household finances to provide a robust statistical analysis of the relationship between indebtedness and partnership dissolution and to avoid the potential simultaneity of financial and psychological health responses that arise when using self reported data on the extent of household financial problems we examine whether the data provides any support for the economic models of divorce and separation developed by gary becker and his colleagues

consumer activism producer groups and production standards we examine competition between groups of producers when consumers prefer costly ethical production technologies consumers are unable to identify or monitor production technologies producers can freeride on their group s reputation by substituting cheaper unethical technologies when an ethical technology is pareto optimal social pressures within competing producer groups can ensure long run dominance of groups relying most heavily on the ethical technology even if social pressures cannot support the choice of the ethical technology in the long run competition between producer groups can increase the average level of adoption of the ethical technology for an arbitrarily long period of time

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

private eradication of mobile public bads we consider analytically the non cooperative behavior of many private property owners who each controls the stock of a public bad such as an invasive weed species infectious disease fire or agricultural pest the stock of the public bad can grow and disperse across a spatial domain of arbitrary size in this setting we characterize the conditions under which private property owners will control or eradicate and determine how this decision depends on property specific environmental features and on the behavior of other landowners we show that high mobility or lower control by others result in lower private control but when the marginal dynamic cost of the bad is sufficiently large we find that complete eradication may be privately optimal despite the lack of consideration of others welfare in these cases eradication arises in the non cooperative game and is also socially optimal so there is in effect no externality finally when property harboring the bad is not owned or is owned in common we derive the side payments required to efficiently control the mobile public bad

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

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

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

breaking free of a stereotype should a domestic brand pretend to be a foreign one consumers in many emerging markets exhibit a pronounced preference for western and global brands while domestic brands are often associated with a cheap but low quality image frustrated with the negative country of origin coo stereotype imposed on them many domestic brands from emerging markets follow a variety of approaches to disguise their coo and pretend to be foreign this paper studies the strategic aspects of this phenomenon we consider an experience good market where consumers learn about each brand s quality using its coo as a prior each firm can invest in product quality or coo dissociation the former generates better quality signals while the latter simply masks the firm s coo identity the analysis reveals a few main insights sharing a reputation leads to a common good problem where firms free ride on each other s quality investments as a high quality firm dissociates itself from the stereotype it ceases to contribute to the coo image but also prevents its low quality peers from free riding on it this incurs a negative direct effect but a positive strategic effect on the group image consequently a country s coo image may actually improve when more high quality brands shun their identities and pretend to be foreign in equilibrium coo image improves monotonically as firms become more efficient in providing quality however the prevalence of coo dissociation may first increase then decrease we discuss the implications of these results for emerging market brands as well as policy makers

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

the economics of nested names name specificity reputations and price premia a good can be identified by its region or country of origin the firm that produces it and its product name in other words names can nest within each other to categorize goods with increasing specificity this article develops a conceptual framework for jointly analyzing the effect of product firm and collective reputations on market price the model is estimated via quantile regression with california wine market data the results portray how the structure and relative importance of reputations change as product prices vary specifically reputation premia migrate from collective to specific names as prices increase

predation reputation and entry deterrence abstract economists often argue that predatory practices are irrational since there exist cheaper or more certain means to gain or maintain a monopoly our gametheoretic equilibrium analysis suggests that if a firm is threatened by several potential entrants then predation may be rational against early entrants even if it is costly when viewed in isolation because it yields a reputation which deters other entrants asymmetric information plays a crucial role in our analysis since it provides the rationale for entrants to base their expectations of the firm s future behavior on its past actions the analysis also suggests methods to treat general reputational phenomena

price and quality cycles for experience goods we explore a dynamic competitive model for experience goods and study an equilibrium for it in which firms plan initially to produce high quality at low price then high quality at high price then low quality at high price each consumer is aware that all firms eventually intend to run down their reputations at customers expense yet he rationally chooses to wait for direct evidence that the firm to which he is attached has already entered into the exploitative phase

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

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

when are private standards more stringent than public standards retailers private standards are increasingly important for addressing consumer concerns about safety quality and social and environmental issues empirical evidence shows that these private standards are frequently more stringent than their public counterparts this article develops a political economy model that helps explain this stylized fact we show that if producers exercise their political power to persuade the government to impose a lower public standard retailers may apply their market power to install a private standard at a higher level than the public one depending on several factors

evaluating the net benefits of collective reputation the case of bordeaux wine in this paper we develop an original approach to assess the net benefits associated with a generic promotion program using an application to bordeaux wines the benefit is computed from the marginal impact of the program s collective reputation on the individual reputation for sub regions within bordeaux these different marginal impacts are estimated using detailed survey data about the image of bordeaux wines in seven european countries we find positive and significant spillover effects from the collective reputation bordeaux that moreover increase with the reputation of the sub region these spillover effects when significantly positive vary from a minimum of 5 to a maximum of 15 of additional favorable quality opinions we then calculate a measure of the average net benefits earned by producers from the regional promotion program in selected sub regions within bordeaux our results indicate that producers in some sub regions are more likely to benefit from the promotion program and suggest that the current fee structure may not be properly aligned with market conditions

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

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

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

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

effective tax rates and guarantees in the afdc program 1967 1982 estimates of effective tax rates on earned and unearned income and estimates of effective guarantees in the afdc program by state are provided for the period 1967 1982 the results indicate that effective real guarantees fell every year from 1967 to 1981 but stabilized in 1982 effective tax rates on unearned income rose steadily from 1967 to 1981 and took a particularly large additional jump in 1982 effective tax rates on earned income fell after 1967 but then gradually rose throughout the 1970s until 1982 when they took a much larger jump thus guarantees fell and tax rates rose over the 1970s as tight budgets forced states to restrict benefits and in the early 1980s tax rates were pushed even higher by federal legislation

collective reputation social norms and participation this paper analyzes a repeated games model of collective reputation with imperfect public monitoring and perfect local peer monitoring of efforts even when peer monitoring is local firms may achieve higher profits under collective reputation by decreasing the cost of maintaining customers trust the optimal number of firms that share a common reputation is greater when 1 trades are more frequent and public information is disseminated more rapidly 2 the deviation gain is smaller compared to the quality premium 3 customers information regarding firms quality is more precise or 4 intragroup information about firms quality is more global from a positive perspective we suggest how social norms can influence the reputation of regional products we also offer an efficiency explanation for food scares from a normative point of view in our model protection of geographical indications increases and mandatory traceability decreases welfare and incentives to provide quality without taking into account direct implementation costs copyright 2012 oxford university press

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

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

towards a differentiated modelling of origin effects in hedonic analysis an application to auction prices of specialty coffee abstract origin matters this has been shown by numerous studies using either discrete choice or hedonic approaches to derive implicit prices for origin as a product attribute in most of the hedonic studies intercept dummies were introduced for specific regional origins and statistically significant coefficients of those variables were seen as an indication of either a superior or inferior reputation compared to products from other origins we argue that hedonic pricing models of this type may be too simple to detect the true origin effects if assessments of a product s sensory quality are available and interact with prior beliefs about reputation based on a supply and demand framework to explain auction prices a reduced form hedonic pricing model is suggested that includes intercept as well as slope dummy effects of the regional origin because reputation and the objective product quality are particularly important for markets of differentiated high quality foods and beverages we analyze electronic auction markets for specialty coffees the findings for the cup of excellence data reveal that it is important to distinguish reputation sensory quality and their interaction as determinants of coffee auction prices as well as varying origin impacts across market segments

till death do us part or i get my pension wives pension holding and marital dissolution in the united states wives financial independence gained from their pension may increase the risk of marital dissolution especially when wives are approaching retirement age the older wives independence hypothesis applying single and simultaneous equations probit models to data from the panel study of income dynamics we investigate the effect of wives pension holding in 1984 on the risk of subsequent marital dissolution results from the single equation model appear to support the older wives independence hypothesis however results from the simultaneous equations model suggest that interpreting the single equation results as a sign of older wives economic independence may be misleading

trends in the well being of american women 1970 1995 this paper examines the trends in the well being of american women over the last 25 years a time of significant changes in the relative economic status of women and in the labor market as a whole a broad range of indicators are considered to capture changes in women s well being in the family as well as in the labor market for virtually all age and education groups substantial evidence is obtained of rising gender equality in labor market outcomes notably labor force participation wages and occupational distributions broad evidence is also found of greater gender parity within married couple families as the housework time of husbands increased relative to wives and the relative wages of wives rose compared to their husbands however parallel to the recent evidence of the declining labor market position of lower skilled men there has been a similar deterioration in the economic status of less educated women especially high school dropouts their labor force participation rates and wages have risen at a much slower pace than those of more highly educated women while their incidence of single headship has increased much more rapidly these findings for less educated women serve to underscore the widening gap between more and less skilled americans of both sexes as well as to emphasize its broad dimensions

labor supply and marital separation panel data are used to estimate the effect of marital separation on labor supply female labor supply increases substantially and male labor supply declines marginally lending support to the theory of specialization within the household the most interesting finding is that women began to increase their labor supply well before the actualsplit occurs suggesting either that shocks to labor supply change divorce probabilities or that women with a higher likelihood of divorcework more this argument is pursued by constructing and estimating a simultaneous model of labor supply and divorce risk copyright 1986 by american economic association

the effect of the u s welfare system on marital status abstract an issue of long standing importance in the u s welfare system has been its lack of neutrality with respect to family composition which generally provides payments only to female headed families that is families with no able bodied male present using data from 1969 to 1985 to examine the issue this study finds that 1 the simple cross sectional correlations between marital status and welfare benefits are almost always in the expected direction but are generally weak in significance 2 that the magnitude and significance of the correlations have nevertheless grown over time and 3 that the correlations for men are no weaker and usually stronger especially for blacks than those for women

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

a reassessment of the effect of income maintenance on marital dissolution in the seattle denver experiment cain and wissoker claim that income maintenance treatment had no effect on marital dissolution in the seattle denver income maintenance experiment yet parametric and nonparametric analyses reveal that there was a significant increase in the dissolution rate for blacks and whites but not chicanos this conclusion holds for many different specifications including a number that allow free form time variation in response while cain and wissoker s analyses and results differ in many ways from that of groeneveld hannan and tuma consideration of the full set of estimates including both main effects and interaction effects and analyses of the complete samples reveal that their analyses agree that the income maintenance treatment increased rates of marital dissolution for blacks and whites

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

the welfare implications of minimum quality standards previous analysis of the social welfare implications of minimum quality standards has yielded no decisive results in this paper the specific nature of consumer and producer responses to quality standards is incorporated into the analysis both consumer and producer gains are shown to be impossible when consumers can perceive quality before purchase even if low quality produce is diverted to secondary markets standards unambiguously reduce net social benefits the paper explores the possibility that minimum quality standards are a form of rent seeking behavior
