sequential formation of coalitions in games with externalities and fixed payoff division this paper analyzes a sequential game of coalition formation when the division of the coalitional surplus is fixed and the payoffs are defined relative to the whole coalition structure gains from cooperation are represented by a valuation which maps coalition structures into payoff vectors i show that any core stable coalition structure can be attained as a stationary perfect equilibrium of the game if stationary perfect equilibria may fail to exist in general games a simple condition is provided under which they exist in symmetric games furthermore symmetric stationary perfect equilibria of symmetric games generate a coalition structure which is generically unique up to a permutation of the players a general method for the characterization of equilibria in symmetric games is proposed and applied to the formation of cartels in oligopolies and coalitions in symmetric majority games journal of economic literatureclassification numbers c78 c71 1996 academic press inc

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

learning about a new technology pineapple in ghana this paper investigates the role of social learning in the diffusion of a new agri cultural technology in ghana we use unique data on farmers communication patterns to define each individual s information neighborhood conditional on many potentially confounding variables we find evidence that farmers adjust their inputs to align with those of their information neighbors who were surpris ingly successful in previous periods the relationship of these input adjustments to experience further indicates the presence of social learning in addition applying the same method to input choices for another crop of known technol ogy correctly indicates an absence of social learning effects jel d83 013 033 q16

the demographic transition and the position of women a marriage market perspective we present international evidence on the marriage market implications of cohort size growth and set out a theoretical model of how marriage markets adjust to imbalances since men marry younger women secular growth in cohort size in the second phase of the demographic transition worsens the position of women this e ect has been substantial in many asian countries earlier and continues to be true in sub saharan africa with fertility decline cohort are now shrinking in east asia improves the position of women these demographic trends can explain the increase and spread in dowries in south asia and the persistence of polygyny in sub saharan africa we show that the age gap at marriage will not adjust in order to equilibrate the marriage market in response to persistent imbalances even though it accommodates transitory shocks jel categories j12 j13 j16

taxation in matching markets what is the impact of taxation in matching markets in matching markets because agents have heterogeneous preferences over potential partners welfare depends on which agents are matched to each other in equilibrium taxes in matching markets can generate inefficiency by changing who is matched to whom even if the number of workers at each firm is unaffected for markets in which workers refuse to match without a positive wage higher taxes decrease match efficiency however in more balanced matching markets where transfers may flow in either direction such as the student college market lowering taxes may decrease match efficiency because an agent can transfer enough to buy an inefficient partner only to be bought back when taxes are lowered further simulations show that in matching markets traditional deadweight loss estimates based on the change in taxable income can be substantially biased in either direction jel classification h20 j24 c78 d13

how do sex ratios affect marriage and labor markets evidence from america s second generation sex ratios i e relative numbers of men and women can affect marriage prospects labor force participation and other social and economic variables but the observed association between sex ratios and social and economic conditions may be confounded by omitted variables and reverse causality this paper uses variation in immigrant flows as a natural experiment to study the effect of sex ratios on the children and grandchildren of immigrants the flow of immigrants affected the second generation marriage market because second generation marriages were mostly endogamous i e to members of the same ethnic group the empirical results suggest that high sex ratios had a large positive effect on the likelihood of female marriage and a large negative effect on female labor force participation perhaps surprisingly the marriage rates of second generation men appear to be a slightly increasing function of immigrant sex ratios higher sex ratios also appear to have raised male earnings and the incomes of parents with young children the empirical results are broadly consistent with theories where higher sex ratios increase female bargaining power in the marriage market

a theory of endogenous coalition structures consider an environment with widespread externalities and suppose that bind ing agreements can be written we study coalition formation in such a setting our analysis proceeds by defining on a partition function an extensive form bargaining game we establish the existence of a stationary subgame perfect equilibrium for such a game our main results are concerned with the characterization of equilib rium coalition structures we develop an algorithm that generates under certain conditions an equilibrium coalition structure our characterization results are especially sharp for symmetric partition functions in particular we provide a uniqueness theorem and apply our results to a cournot oligopoly journal of economic literature classification numbers c71 c72 c78 d62 q 1999 academic press

marginal contributions and externalities in the value our concern is the extension of the theory of the shapley value to problems involving externalities using the standard axiom systems behind the shapley value for an arbitrary exogenous coalition structure leads to the identification of bounds on players payos around an externality free value in endogenizing the coalition structure we analyze a two stage process of coalition formation in whose second stage our axiomatic results are applied we find reasons to explain inecient coalition structures and provide sucient conditions for eciency

effects of deregulation and consolidation of the broadcast television industry this paper exploits deregulation in the 1990s to estimate viewership and revenue effects of consolidation in broadcast television then finds cost effects that explain the ownership structure given viewer ship and revenue effects results suggest that consolidation greatly increased profitability in an industry with otherwise declining profitability groups with broader national coverage attract more advertising per station joint ownership of two stations within a market and network ownership both allow for significant cost savings there is some evidence that within market consolidation allows stations to achieve local market power however both within market and across market consolidation appear to have boosted viewership on net jel g32 l13 l25 l51 l82 l88 deregulation of the telecommunications industry in the 1990s led to substantial consolidation in the local broadcast television industry which provoked considerable controversy critics of the deregulation argue that cost cutting led to lower quality programming broadcast groups counter that consolidation is necessary to make high quality broadcast programming viable in the face of increasing competition from other content providers that are not subject to the same strict ownership regulations as broadcasters to what extent did the consolidation that took place in the decade following deregulation actually improve the profitability of broadcast stations is there any evidence that consolidation had negative effects such as reduced programming quality or local market power a priori the answers are not obvious due to remaining regulations the vast majority of consolidation involved stations in different local markets which are not in direct competition with one another and are often hundreds of miles apart how does nexstar broadcasting s ownership of an nbc affiliated station in

the marriage squeeze interpretation of dowry inflation a comment in a recent paper rao 1993 advanced a marriage squeeze explanation to the secular rise in real dowries so called dowry inflation witnessed in india arguing that the relevant ages with respect to marriage are 10 19 for women and 20 29 for men rao found that the ratio of women to men in those age groups had increased over time moreover this sex ratio was found to have a positive and significant impact on dowry when one controls for differences in traits of brides and grooms the empirical results presented here suggest that rao s findings are not robust using the same data i fail to replicate his main result that is that the sex ratio women 10 19 men 20 29 has a positive impact on dowries moreover rao s specification regressing dowries on differences in spouses traits bride s minus groom s imposes the restriction that attributes influence dowries in a symmetrical fashion ignoring compelling evidence against that assumption i find that regressing dowry on individual traits instead of differences improves the model fit considerably

analyzing the relationship between organic and sponsored search advertising positive negative or zero interdependence the phenomenon of paid search advertising has now become the most predominant form of online advertising in the marketing world however we have little understanding of the impact of search engine advertising on consumers responses in the presence of organic listings of the same firms in this paper we model and estimate the interrelationship between organic search listings and paid search advertisements we use a unique panel data set based on aggregate consumer response to several hundred keywords over a three month period collected from a major nationwide retailer store chain that advertises on google in particular we focus on understanding whether the presence of organic listings on a search engine is associated with a positive a negative or no effect on the click through rates of paid search advertisements and vice versa for a given firm we first build an integrated model to estimate the relationship between different metrics such as search volume click through rates conversion rates cost per click and keyword ranks a hierarchical bayesian modeling framework is used and the model is estimated using markov chain monte carlo methods our empirical findings suggest that click throughs on organic listings have a positive interdependence with click throughs on paid listings and vice versa we also find that this positive interdependence is asymmetric such that the impact of organic clicks on increases in utility from paid clicks is 3 5 times stronger than the impact of paid clicks on increases in utility from organic clicks using counterfactual experiments we show that on an average this positive interdependence leads to an increase in expected profits for the firm ranging from 4 2 to 6 15 when compared to profits in the absence of this interdependence to further validate our empirical results we also conduct and present the results from a controlled field experiment this experiment shows that total click through rates conversions rates and revenues in the presence of both paid and organic search listings are significantly higher than those in the absence of paid search advertisements the results predicted by the econometric model are also corroborated in this field experiment which suggests a causal interpretation to the positive interdependence between paid and organic search listings given the increased spending on search engine based advertising our analysis provides critical insights to managers in both traditional and internet firms

semiparametric duration models in this article we consider semiparametric duration models and efficient estimation of the parameters in a non iid environment in contrast to classical time series models where innovations are assumed to be iid we show that in for example the often used autoregressive conditional duration acd model the assumption of independent innovations is too restrictive to describe financial durations accurately therefore we consider semiparametric extensions of the standard specification that allow for arbitrary kinds of dependencies between the innovations the exact nonparametric specification of these dependencies determines the flexibility of the semiparametric model we calculate semiparametric efficiency bounds for the acd parameters discuss the construction of efficient estimators and study the efficiency loss of the exponential pseudolikelihood procedure this efficiency loss proves to be sizeable in applications for durations observed on the paris bourse for the alcatel stock in july and august 1

environment versus growth a criticism of degrowth and a plea for a growth in recent debates on environmental problems and policies the strategy of degrowth has appeared as an alternative to the paradigm of economic growth this new notion is critically evaluated by considering five common interpretations of it one conclusion is that these multiple interpretations make it an ambiguous and rather confusing concept another is that degrowth may not be an effective let alone an efficient strategy to reduce environmental pressure it is subsequently argued that a growth i e being indifferent about growth is a more logical social aim to substitute for the current goal of economic growth given that gdp per capita is a very imperfect indicator of social welfare in addition focusing ex ante on public policy is considered to be a strategy which ultimately is more likely to obtain the necessary democratic political support than an ex ante explicit degrowth strategy in line with this a policy package is proposed which consists of six elements some of which relate to concerns raised by degrowth supporters

urban public transport companies and strategies to promote sustainable consumption practices abstract development policy adopted by governments and companies increasingly pays attention to issues of sustainability one dominant strategy emphasizes behavioural change vis a vis technological innovation however often attempts at changing individual and collective behaviour is ineffective one of the main reasons for this failure is that policy makers do not consider the gap between values and practices we propose to address this gap by using theories of practice which give centrality to reflexivity in the analysis of practices and have long been applied in research on environmental behaviours we will use the example of the transport sector which has long been a major contributor to climate change and technological improvements have not been enough to make up for the growth of impacts focusing on the role of a transport company in promoting sustainability through behavioural change the main goal of this article is to analyse transport practices from the supplier s perspective choices made by transport companies towards green technologies are strongly limited by available economic resources by the public policies and by the fuel market results also reinforce the idea that the economic dimension constrains the strategies to reduce environmental impacts

estimation of high frequency volatility an autoregressive conditional duration approach we propose a method to estimate the intraday volatility of a stock by integrating the instantaneous conditional return variance per unit time obtained from the autoregressive conditional duration acd model called the acd icv method we compare the daily volatility estimated using the acd icv method against several versions of the realized volatility rv method including the bipower variation rv with subsampling the realized kernel estimate and the duration based rv our monte carlo results show that the acd icv method has lower root mean squared error than the rv methods in almost all cases considered this article has online supplementary material

serial dictatorship and pareto optimality abstract in a deterministic allocation problem in which each agent is entitled to receive exactly one object an allocation is pareto optimal if and only if it is the outcome of a serial dictatorship we extend the definition of serial dictatorship to settings in which some agents may be entitled to receive more than one object and study the efficiency and uniqueness properties of the equilibrium allocations we prove that subgame perfect equilibrium allocations of serial dictatorship games are not necessarily pareto optimal and generally not all pareto optima can be implemented as subgame perfect equilibrium allocations of serial dictatorship games except in the 2 agent separable preference case moreover serial dictatorship games do not necessarily have unique subgame perfect equilibrium allocations except in the 2 agent case hence their outcomes are indeterminate and manipulable

accounting for racial differences in marriage and employment what can account for the differences in marriage and employment decisions across blacks and whites to answer this question i develop a dynamic equilibrium model of marriage two explanations for the racial differences in behavior are considered differences in population supplies and wages black white differences in population supplies explain one fifth of the difference in marriage rates and between one fifth and one third of the differences in employment rates across race removing the racial gap in wages eliminates the differences in employment but increases the differences in marriage rates

the rising price of husbands a hedonic analysis of dowry increases in rural india dowries in south asia have steadily risen over the last 40 years and now often amount to over 50 percent of a household s assets this paper attempts to investigate the reasons behind this increase it adapts rosen s implicit market model to the indian marriage market and tests predictions from the model with data from six villages in south central india and from the indian census it is found that a marriage squeeze caused by population growth resulting in larger younger cohorts and hence a surplus of women in the marriage market has played a significant role in the rise in dowries

large matching markets as two sided demand systems this paper studies two sided matching markets with non transferable utility when the number of market participants grows large we consider a model in which each agent has a random preference ordering over individual potential matching partners and agents types are only partially observed by the econometrician we show that in a large market the inclusive value is a sufficient statistic for an agent s endogenous choice set with respect to the probability of being matched to a spouse of a given observable type furthermore while the number of pairwise stable matchings for a typical realization of random utilities grows at a fast rate as the number of market participants increases the inclusive values resulting from any stable matching converge to a unique deterministic limit we can therefore characterize the limiting distribution of the matching market as the unique solution to a fixed point condition on the inclusive values finally we analyze identification and estimation of payoff parameters from the asymptotic distribution of observable characteristics at the level of pairs resulting from a stable matching

the impact of conditional cash transfers on marriage and divorce abstracta growing number of less developed countries have introduced conditional cash transfer programs in which funds are targeted to women economic models of the family suggest that these transfer programs may lead to marital turnover among program beneficiaries data from the experimental evaluation of the progresa program in mexico is used to provide new evidence on the short run impacts of targeted transfers on couples union dissolution and individuals new union formation decisions we find that although the overall share of women in union does not change as a result of the program marital turnover increases intact families eligible for the transfers experienced a modest 0 32 percentage points increase in separation rates with most of the effect concentrated among young and relatively educated women households in contrast young single women with low educational attainment levels experienced a substantial increase in new union formation rates the marital transition patterns are consistent

matching value and market design in online advertising networks an empirical analysis advertising networks have recently played an increasingly important role in the online advertising market critical to the success of an advertising network are two mechanisms an allocation mechanism that efficiently matches advertisers with publishers and a pricing scheme that maximally extracts surplus from the matches in this paper we quantify the value and investigate the determinants of a successful advertiser publisher match using data from taobao s advertising network a counterfactual experiment reveals that the platform s profit under a decentralized allocation mechanism is close to the profit level when the platform centrally assigns the matching under perfect platform knowledge of matching values in another counterfactual experiment we explore the effect of platform technology and revenue model on the strategic choice of the pricing schemes of list price versus generalized second price gsp auction pricing we find that platforms that profit from the advertiser side may have less incenti

can t buy me love a field experiment exploring the trade off between income and caste status in an indian matrimonial market i introduction the relationship between economic motive and observance of discriminatory social customs is hardly new to economists this is implicit in the writings of becker 1957 1973 1974 on discrimination and other social customs and explicit in arrow s essay 1972 on discrimination and akerlof s work 1980 on the interactive relationship between economic incentives and discriminatory social customs as scholars like becker arrow and akerlof have investigated the relationship between economic incentives and the prevalence of custom based discrimination of which status based discrimination is an example it is natural to consult the related empirical evidence on the impact of economic incentives on the extent of status based discrimination surprisingly the extant empirical literature is mostly silent on how economic incentives may directly interact with status based discrimination 1 this is atypical as one would be hard pressed to find an issue as weighty as status based discrimination yet our knowledge in this aspect remains oddly limited our study aspires to rectify this gap this study investigates whether and what magnitude of economic incentive can diminish the incidence of status based discrimination by designing a controlled field experiment in an actual marketplace a reputable arranged marriage market that is conducted via newspaper advertisements the existing literature suggests that this market might be especially prone to strong discriminatory mate selection behavior based on the social identity status of an individual where caste identity of an individual is an easily measured indicator of social status the genesis of this discrimination can be attributed to a high status female s concern for a decline in her social status if she engages in a marital relationship with a low status male against this backdrop we ask whether a low status male could attempt to weaken this enduring form of discrimination by providing systematic economic incentive in the form of high monthly groom incomes to a high status female so that the former s marriage proposal receives preliminary consideration by the latter conditional on both individuals participation in this market the marketplace that we utilize is a well functioning arranged marriage market conducted via matrimonial advertisements in a widely circulated bengali language newspaper marriageable males in this market typically advertise their caste and income information among other attributes after these advertisements appear in the newspaper interested families contact the advertiser mostly in form of detailed letters expressing their interest in that advertisement this provides a confidential and reliable measure of first intent of the interested party in this case females therefore the conjunction of an exceptionally strong status based mate selection behavior a reputed market for arranged marriages and an exclusive correspondence process furnish us with a unique opportunity to investigate the main research hypothesis of our study to the best of our knowledge this is the first field experiment that exclusively focuses on how economic incentives can influence status based discrimination in an actual market 2 to operationalize the experiment we create nine unique matrimonial advertisements each representing a fictitious groom type 3 these potential grooms belong to one of the three blocks where each block contains three grooms from a given caste group we vary the caste status across these blocks we consider three different caste groups high middle and low strictly ranked so in the study region we vary the income features of grooms within a block we consider three different monthly income levels i e high medium and low that are considered feasible for each caste group in the study region furthermore we randomly assign other characteristics relevant for this market to all the potential grooms so that these features on average do not affect the behavior of responders

understanding the link between collaborative economy and sustainable behaviour an empirical investigation abstract the collaborative economy is growing at an exponential rate and the accommodation sector is especially affected the relevance of the phenomenon is linked with sustainable consumption that encourages resource efficiency waste reduction development of better products and surplus reutilization due to overproduction and overconsumption this paper aims at investigating the relationship between collaborative consumption and the adoption of sustainable practices from the users perspective after identifying the gaps existing in the literature different research approaches were integrated at first 4 focus groups were conducted to detect the main attributes and benefits attached to collaborative economy in tourism the personal values instrumental and terminal values relevant to p2p accommodation renting were identified through laddering technique as the propensity to put in place sustainable behaviour thereafter a structural model based on the framework of the theory of planned behaviour tpb constructs was set and tested to understand its consistency with the above values an ad hoc questionnaire was projected and administered online based on a sample of 384 respondents quantitative data were analysed through statistical and structural equation modeling software from an academic perspective the paper enhances the current knowledge in identifying the desired end states that users want to achieve by renting a p2p accommodation moreover it exploits and adapts the tpb to an emerging consumption model such as collaborative economy thus disclosing the relation between collaborative consumption and sustainable behaviour moreover the adaptation of tpb model to the newest context of collaborative economy expands the knowledge related to sustainable consumption from a managerial perspective it is necessary to emphasize the importance of defining a new business paradigm considering collaborative consumption to support environmental policy and encouraging sustainable behaviour

still waiting for mister right asymmetric information abortion laws and the timing of marriage previous studies have suggested that more liberal abortion laws should lead to a decrease in marriage rates among young women as shotgun weddings are no longer necessary empirical evidence from the united states lends support to that hypothesis this article presents an alternative theory of abortion access and marriage based on the cost of search which suggests that more liberal abortion laws may actually promote young marriage an empirical examination of marriage data from eastern europe shows that countries that liberalized their abortion laws saw an increase in marriage rates among nonteenage women

sorting multidimensional types theory and application this article studies multidimensional matching between workers and jobs workers differ in manual and cognitive skills and sort into jobs that demand different combinations of these two skills to study this multidimensional sorting problem i develop a theoretical framework that generalizes the unidimensional notion of assortative matching and sufficient conditions on the technology under which sorting obtains i derive the equilibrium in closed form and use this explicit solution to study biased technological change the main finding is that an increase in worker job complementarities in cognitive relative to manual inputs leads to more pronounced sorting and wage inequality across cognitive relative to manual skills this can trigger wage polarization and boost aggregate wage inequality i then estimate the model for the u s and identify sizable technology shifts during the last two decades worker job complementarities in cognitive inputs strongly increased whereas complementarities in manual inputs decreased in addition to this bias in complementarities there has been a cognitive skill bias in production counterfactual exercises suggest that these technology shifts as opposed to changes in skill supply and demand can account for observed changes in worker job sorting wage polarization and a significant part of the increase in u s wage dispersion

who marries whom and why this paper proposes and estimates a static transferable utility model of the marriage market the model generates a nonparametric marriage matching function with spillover effects it rationalizes the standard interpretation of marriage rate regressions and points out its limitations the model was used to estimate u s marital behavior in 1971 72 and 1981 82 the marriage matching function estimates show that the gains to marriage for young adults fell substantially over the decade unlike contradictory marriage rate regression results the marriage matching function estimates showed that the legalization of abortion had a significant quantitative impact on the fall in the gains to marriage for young men and women

a direct test of the efficient marriage market hypothesis this paper takes gary becker s theory of marriage seriously in his seminal paper becker 1973 proposes an invisible hand theorem for the marriage market he argues that the competition for spouse leads men and women to be matched in such a way that maximizes the sum total of marital output applications of the economic approach to marriage are now commonplace becker et al 1977 study the effect of imperfect information on divorce benham 1974 scully 1979 and wong 1986 estimate the effect of wife s education on husband s earnings grossbard shechtman 1993 and rao 1993 focus on the effect of sex ratio on implicit or explicit bride prices or dowries the literature however has virtually ignored becker s hypothesis that marriage markets maximize total marital output i e that marriage markets are efficient mistakes are no doubt made in marriage decisions the marriage market is not a text book example of perfect competition because of elaborate social norms substantial search costs and room for bargaining and opportunistic behavior nevertheless we intend to push becker s efficient marriage market model at face value and directly confront it with data the hypothesis that the marriage market maximizes marital output provides a framework that allows estimating a model of spouse selection which recovers some of the parameters of the production function for marital output using the estimated parameters we can use programming techniques to find the optimal male female pairing that maximizes the sum of marital output the degree to which the actual pairing of husbands and wives corresponds to the optimal pairing provides a goodness of fit test of the efficient marriage market hypothesis our method is applied to census data in hong kong a model of spouse selection and other matching models differs from a discrete choice model e g mcfadden 1984 in two important ways first the choice of a spouse is mutual not only does each man choose a woman that yields him the highest net utility but each woman also picks a man that gives her the highest net utility second in a discrete choice model several individuals can choose the same alternative in marriage markets this is prohibited under monogamy thus new methods have to be developed to analyze choice in marriage markets although marital output and the shadow price of husbands and wives are not observable the theory of optimal matching allows us to write down the likelihood function for the observed choice of marital partners it turns out that this model of spouse selection reduces to a version of the tobit model under the assumption that error terms are independently and identically normal in multinomial logit models the interpretation of parameters is cumbersome especially when the number of alternatives is large in our model of spouse selection the estimated parameters are directly related to the production function of marital output the signs of these parameters can be used to address the issue of positive versus negative assortative mating the model can also be used to test marginal product pricing in the marriage market with the estimated production function from the model of spouse selection we can impute the marital output for all possible male female pairs using these imputed output figures the optimal pairing between men and women that maximizes the sum of marital output can be found using an algorithm that solves the assignment problem the degree to which this optimal pairing corresponds to the observed pairing then provides a natural way of assessing marriage market efficiency given the limited range of information contained in the census we find that our model of spouse selection fits the observed choices better than other models such as one based on ranking method following varian s 1990 proposal for goodness of fit tests for optimizing models we derive a measure of efficiency which is based on the distance between total imputed marital output under observed matching and that under optimal matching

designing random allocation mechanisms theory and applications randomization is commonplace in everyday resource allocation we generalize the theory of randomized assignment to accommodate multi unit allocations and various real world constraints such as group specific quotas controlled choice in school choice and house allocation and scheduling and curriculum constraints in course allocation we develop new mechanisms that are ex ante efficient and fair in these environments and that incorporate certain non additive substitutable preferences we also develop a utility guarantee technique that limits ex post unfairness in random allocations supplementing the ex ante fairness promoted by randomization this can be applied to multi unit assignment problems and certain two sided matching problems jel c78 d82

specifying a structural matching game of trading networks with transferable utility structural estimation of matching games with transferable utility including matching games of trading networks and many to many matching is increasingly popular in empirical work i explore several modeling decisions that need to be made when specifying a structural model for a matching game one decision is the choice of a game theoretic solution concept to impose in the structural model i discuss pairwise stability competitive equilibrium and noncooperative games such as auctions another decision is whether to work with a continuum of agents or a finite number of agents i explore other issues as well

aggregation in matching markets this article develops aggregate relations for a matching market of heterogeneous suppliers and demanders under particular assumptions about the distribution of preferences and the matching game asymptotic aggregate relations for the number of realized matches of different types in the presence of flexible contracts such as a price are derived simulation experiments demonstrate that the model also provides excellent predictions in small populations the potential for applications within demographic labor market and welfare analyses is discussed

coalitional strategy proof house allocation abstract we consider house allocation without endowments we show that there is a unique maximal domain including all strict preferences on which efficiency and coalitional strategy proofness are compatible a preference relation belongs to the unique maximal domain if it is a strict descending ranking of houses to a certain house and indifference holds over it and the remaining houses we also show that on this domain mixed dictator pairwise exchange rules are the only rules satisfying efficiency and coalitional strategy proofness journal of economic literature classification numbers c78 d63 d71

birth control and female empowerment an equilibrium analysis we analyze from a theoretical perspective the impact of innovations in birth control technology on intrahousehold allocation of resources we consider a model of frictionless matching on the marriage market in which men as well as women differ in their preferences for children moreover men unlike women must marry to enjoy fatherhood we show that more efficient birth control technologies generally increase the power hence the welfare of all women including those who do not use them this empowerment effect requires that the new technology be available to single women an innovation reserved to married women may result in a disempowerment effect

structural estimation of marriage models a structural approach is used to examine who matches with whom a two sided matching model that allows for marital sorting in response to marriage market flexibility and agents preferences is utilized estimation is based on imbedding the numerical solution of a matching model within a maximum likelihood procedure results indicate that wage is more desirable than education in predicting marriageability for white men education is more desirable for black men the marriage market for white men is more flexible both marriage market flexibility and the chance of being classified correctly using agents wage and education decrease with age for white men

estimation of time varying adjusted probability of informed trading and probability of symmetric order flow shock summary recently duarte and young 2009 studied the probability of informed trading pin proposed by easley et al 2002 and decomposed it into two parts the adjusted pin apin as a measure of asymmetric information and the probability of symmetric order flow shock psos as a measure of illiquidity they provide some cross section estimates of these measures using daily data over annual periods in this paper we propose a method to estimate daily apin and psos by extending the method in tay et al 2009 using high frequency transaction data our empirical results show that while pin is positively contemporaneously correlated with variance apin is not on the other hand psos is positively correlated with daily average effective spread and variance which is consistent with the interpretation of psos as a measure of illiquidity compared to apin psos exhibits clustering and sporadic bursts over time copyright 2012 john wiley sons ltd

two sex demographic models classical stable population theory the standard model of population age structure and growth is ill suited to addressing many issues that concern economists and demographers because it is a one sex theory this paper investigates the existence uniqueness and dynamic stability of equilibrium in the birth matrix mating rule bmmr model a new model of age structure and growth for two sex monogamously mating populations the paper shows by means of examples that the bmmr model can have multiple nontrivial equilibria and establishes sufficient conditions for uniqueness it generalizes a theorem of w brian arthur to nonlinear systems and uses it to establish sufficient conditions for local dynamic stability

conditional duration models for high frequency data a review on recent developments this paper reviews the recent literature on conditional duration modeling in high frequency finance these conditional duration models are associated with the time interval between trades price and volume changes of stocks traded in a financial market an earlier review by pacurar provides an exhaustive survey of the first and some of the second generation conditional duration models we consider almost all of the third generation and some of the second generation conditional duration models notable applications of these models and related empirical studies are discussed the paper may be seen as an extension to pacurar

on the state of the union an overlapping generations model of marriage and divorce is constructed to analyze family structure and intergenerational mobility agents differ by sex marital status and human capital single agents meet in a marriage market and decide whether to accept or reject proposals to wed married couples must decide whether to separate or not parents invest in their children depending on their wherewithal a simulated version of the theoretical prototype can generate an equilibrium with a significant number of female headed families and a high degree of persistence in income across generations to illustrate the model s mechanics the effects of two antipoverty policies namely child support and welfare are investigated

separate spheres bargaining and the marriage market this paper introduces the separate spheres bargaining model a new model of distribution within marriage it differs from divorce threat bargaining models e g manser brown mcelroy horney in that the threat point is not divorce but a noncooperative equilibrium within marriage this noncooperative equilibrium reflects traditional gender roles the predictions of our model thus differ from those of divorce threat bargaining models in the separate spheres model cash transfer payments to the mother and payments to the father can but need not imply different equilibrium distributions in existing marriages in the long run the distributional effects of transfer policies may be substantially altered by changes in the marriage market equilibrium

exclusive nightclubs and lonely hearts columns non monotone participation in optional intermediation in many decentralised markets the traders who benefi tm ost from an exchange do not employ intermediaries even though they could easily afford them at the same time employing intermediaries is not worthwhile for traders who benefit little from trade together these decisions amount to non monotone participation choices in intermediation only traders of middle type employ intermediaries while the rest the high and the low types prefer to search for a trading partner directly we provide a theoretical foundation for this hitherto unexplained phenomenon we build a dynamic matching model where a trader s equilibrium bargaining share is a convex increasing function of her type we also show that this is indeed a necessary condition for the existence of non monotone equilibria

efficiency in coalition games with externalities a natural extension of superadditivity is not sufficient to imply that the grand coalition is efficient when externalities are present we provide a condition analogous to convexity that is sufficient for the grand coalition to be efficient and show that this also implies that the appropriately defined core is nonempty moreover we propose a mechanism which implements the most efficient partition for all coalition formation games and characterizes the resulting payoff division

gender based price discrimination in matching markets this paper develops a new model to analyze price discrimination in matching markets where agents have private information about their respective qualities on the basis of signals car clothing club membership etc purchased from profit maximizing firms men and women form beliefs about each other s qualities the matching must then be stable in the following sense there cannot be a man and woman who are unmatched and who both believe they would be better off if they were matched with one another the model enables an analysis of the impact of third degree or gender based price discrimination on welfare when third degree price discrimination is not feasible the cost of eliciting private information is higher but a monopoly intermediary may have stronger incentives to implement an efficient allocation i show that gender based price discrimination is more likely to have a positive impact the more symmetric the matching environment is

for better or for worse the long term effects of postwar reconstruction on family formation abstractthis article estimates the long term legacies of female labour force mobilization on women s family formation outcomes such as marriage age at first marriage and divorce we identify the long term marriage effects of female labour force mobilization by exploring postwar mandatory employment in germany using difference in differences analysis we find that participation in postwar reconstruction efforts increased women s probability of being currently married ever married and marrying at younger ages we also find that postwar employment had no differential effect on divorce rates of the affected cohorts of women these results persist after accounting for the potential changes in the composition of the population demand for female labour war relief payments and postwar state specific policies

an empirical model of the medical match abstract this paper develops a framework for estimating preferences in a many to one matching market using only observed matches i use pairwise stability and a vertical preference restriction on one side to identify preferences on both sides of the market counterfactual simulations are used to analyze the antitrust allegation that the centralized medical residency match is responsible for salary depression due to residents willingness to pay for desirable programs and capacity constraints salaries in any competitive equilibrium would remain on average at least 23 000 below the marginal product of labor therefore the match is not the likely cause of low salaries jel c78 i11 j31 j44 k21 l44
