bargaining on behalf of a constituency abstract we study bargaining situations in which one side consists of a group of people who elect a representative to bargain with another party on their behalf a two phase bargaining model is developed in which a principal agent problem between the constituency and its representative is embedded with a natural refinement of sequential equilibrium we characterize the set of equilibria and examine its efficiency properties we show that agency problems in the delegation relationship rather than asymmetric information between the two bargainers can cause severe bargaining inefficiency i e delay in reaching agreements extensions of the model and applications to union firm bargaining are then discussed briefly journal of economic literature classification numbers c78 d82 j52

gender differences in wages and job turnover among continuously employed workers the purpose of this paper is to determine whether a significant number of u s women work continuously during their early careers which women are likely to do so and how these women compare to men in terms of their interfirm mobility and earnings the data are from the young men and young women cohorts of the national longitudinal surveys of labor market experience nls continuous employment is by no means the norm among young women but it appears to be a growing trend in comparing starting wages of men and women we find that the wage gap is less pronounced among continuously employed workers than among the full sample in almost every race cohort schooling group and the gap is narrowing far more rapidly among the continuously employed excerpt

income distribution political instability and investment abstract this paper successfully tests on a sample of 71 countries for the period 1960 85 the following hypotheses income inequality by fuelling social discontent increases sociopolitical instability the latter by creating uncertainty in the politico economic environment reduces investment as a consequence income inequality and investment are inversely related since investment is a primary engine of growth this paper identifies a channel for an inverse relationship between income inequality and growth we measure socio political instability with indices which capture the occurrence of more or less violent phenomena of political unrest and we test our hypotheses by estimating a two equation model in which the endogenous variables are investment and an index of socio political instability our results are robust to sensitivity analysis on the specification of the model and the measure of political instability and are unchanged when the model is estimated using robust regression techniques

factors affecting levels and growth rates in the wage rates of women evidence from nursing using data from two surveys of nurses 1981 and 1989 the study examines the factors affecting the levels and growth rates in the wage rates paid to women especially married women who were licensed as registered nurses our results indicate that the influence of such household characteristics as marital status age and number of children and spouse s characteristic tended to diminish over the 1980s the evidence further suggests that the penalties for frequent switches in employment state were larger at the end of the decade than at the beginning further wages paid to nurses with baccalaureates were statistically the same as those paid to nurses with lesser formal education the return to the baccalaureate appears to be in the form of the higher wages and salaries earned by those who obtain post baccalaureate degrees

the gender gap in early career wage growth in the uk the gender pay gap on entry to the labour market is approximately zero but ten years after labour market entry there is a gender wage gap of almost 25 log points this article explores the reason for this gender gap in early career wage growth considering three main hypotheses human capital job shopping and psychological theories human capital factors can explain about 11 log points job shopping about 1 5 log points and the psychological theories up to 4 5 log points depending on the specification but a substantial unexplained gap remains women who have continuous full time employment have had no children and express no desire to have them earn about 8 log points less than equivalent men after 10 years in the labour market

in view of ratification governmental preferences and domestic constraints at the amsterdam intergovernmental conference the bargaining product of the amsterdam intergovernmental conference the amsterdam treaty dwindled down the draft proposal to a consensus set of all fifteen member states of the european union eu using the two level concept of international bargains we provide a thorough analysis of how this consensus set was reached by issue subtraction with respect to domestic ratification constraints drawing on data sets covering the positions of all negotiating actors and ratifying national political parties we first highlight the differences in the amsterdam ratification procedures in the fifteen member states of the eu this analysis allows us to compare the varying ratification difficulties in each country second our empirical analysis of the treaty negotiations shows that member states excluded half of the amsterdam bargaining issues to secure a smooth ratification because member states with higher domestic ratification constraints performed better in eliminating uncomfortable issues at the amsterdam intergovernmental conference issue subtraction can be explained by the extent to which the negotiators were constrained by domestic interests

managing domestic differences in international negotiations the strategic use of internal side payments when nations negotiate often the toughest bargaining is not between nations but within them the reason is simple proposed international agreements no matter how much in the national interest inevitably have differential effects on factional concerns threatening to make winners of some and losers of others potential losers often have the power to prevent agreements not to their liking thereby limiting what is possible in international negotiations this article uses a negotiation analytic framework to analyze the consequences of such limits it argues that limits need not be a liability for a divided country under some circumstances they may provide a bargaining advantage and demonstrates circumstances under which intracountry differences are desirable and undesirable from a national perspective more specifically the article shows that the effect of domestic differences on international negotiations depends on the configuration of domestic interests on the nature of domestic political processes and on characteristics of the international bargain it then explores a particular dimension of the domestic process the ability to link issues which allow factions to make internal side payments it demonstrates that internal issue linkage can have profound effects on the external bargain and explores the strategic implications of side payments for those who would manage domestic differences in international negotiations

side payments versus security cards domestic bargaining tactics in international economic negotiations the literature on international economic cooperation has devoted relatively little attention to domestic bargaining tactics and their determinants recent scholarship has tended to stress the utility and frequency of side payments while discounting other prominent bargaining tactics and a broader understanding of tactical choice this article argues that policymakers choose among domestic bargaining tactics to garner support when faced with situations in which other government officials or societal interest groups block the ratification of international economic agreements focusing on offers of side payments and attempts at issue redefinition the article s findings suggest that differences in domestic resistance to proposals of material compensation and in external security threat may explain choices between those tactics in domestic bargaining

wages in high tech start ups do academic spin offs pay a wage premium due to their origin in universities academic spin offs operate at the forefront of technological development therefore academic spin offs exhibit a skill biased labour demand i e academic spin offs have a high demand for employees with cutting edge knowledge and technical skills in order to accommodate this demand academic spin offs may have to pay a relative wage premium compared to other high tech start ups however neither a comprehensive theoretical assessment nor the empirical literature on wages in start ups unambiguously predicts the existence and the direction of wage differentials between academic spin offs and non spin offs this paper addresses this research gap and examines empirically whether or not academic spin offs pay their employees a wage premium using a unique linked employer employee data set of german high tech start ups we estimate mincer type wage regressions applying the hausman taylor panel estimator our results show that academic spin offs do not pay a wage premium in general however a notable exception to this general result is that academic spin offs that commercialise new scientific results or methods pay a wage premium to employees with links to the university sector either as university graduates or as student workers

a note on network formation with decay abstract this paper studies an endogenous network formation with decay we introduce a strategic form game based on a simple bilateral cost allocation rule we show that a strong nash equilibrium of this game always exists and necessarily achieves efficient networks

trends in the male female wage gap the 1980s compared with the 1970s 1 introduction an interesting pattern emerges when contrasting men s and women s wage growth in the 1970s and 1980s from 1979 to 1989 female wages grew 1 7 per annum faster than male wages this wage growth in the 1980s resulted in a 17 narrowing of the gender wage gap on the other hand from 1969 to 1979 female wages grew at a rate only 0 39 per year faster than male wages resulting in very little narrowing of the gender wage gap blau 1998 as noted by smith and ward 1989 these contrasting trends puzzled many because it is well known that female work behavior shot up more dramatically in the 1970s than in the 1980s if female wage growth is related to increasing labor force activity one would have expected the male female wage gap to narrow more in the 1970s than in the 1980s the purpose of this paper is to identify some of the reasons why the male female wage gap narrowed more quickly in the 1980s than in the 1970s despite a deceleration of the growth in female labor force activity in the 1980s what appears to be the case is that predominantly younger and less experienced females entered the labor force in the 1970s the entry of women with relatively little human capital brought down the growth in women s average human capital o neill 1985 so that despite the upsurge of women s labor force participation in the 1970s women s average human capital relative to men s increased more slowly in the 1970s than in the 1980s this relatively slower growth in women s human capital appears to have played itself out in the 1980s both because the number of women joining the labor force slowed and because women s labor force attachment as measured by the proportion of potential work years actually worked increased blau 1998 with these trends average female human capital increased in the 1980s resulting in greater overall wage gains because of the stark differences between the 1970s and 1980s this paper concentrates on distinguishing the factors that contribute to men s and women s wage growth in the two decades despite the substantial literature on the male female wage gap the interdecade difference in the trend has not been adequately examined in what follows this paper uses the panel study of income dynamics psid to illustrate the effects of the demographic changes alluded to above 1 first it presents wage trends for the 1970s and 1980s second it provides direct measures of changes in human capital growth within each decade third to illustrate the importance of these demographic trends especially how new young labor market entrants bring down wages it shows that the higher relative female wage growth in the 1980s is reduced and the relatively slower female wage growth in the 1970s is enhanced when one controls for individual human capital characteristics these effects are illustrated first by including actual experience type variables in a regression whose coefficients measure wage growth and second by eliminating new entrants from 1970s and 1980s regression analysis the paper shows that with these controls increases in female average growth in both the 1970s and 1980s were more comparable than previously thought 2 recent literature on trends in the male female wage gap this is not the first paper to recognize the trend in male female wage convergence o neill 1985 blau and beller 1988 smith and ward 1989 goldin 1990 katz and murphy 1992 wellington 1993 o neill and polachek 1993 blau and kahn 1997 and blau 1998 all note that women s wages have risen relative to men smith and ward 1989 find that female relative wages rose between 1920 and 1980 when adjusting for worker skills goldin 1990 piecing together various data sources finds a similar long term narrowing according to her the ratio of female to male earnings in the economy as a whole rose from 0 46 to 0 56 during the period 1890 to 1930 but was virtually stable from 1950 to around 1980 p

an alternative test of racial prejudice in motor vehicle searches theory and evidence we propose a simple model of trooper behavior to design empirical tests for whether troopers of different races are monolithic in their search behavior and whether they exhibit relative racial prejudice in motor vehicle searches our test of relative racial prejudice provides a partial solution to the well known infra marginality and omitted variables problems associated with outcome tests when applied to a unique data set from florida our tests soundly reject the hypothesis that troopers of different races are monolithic in their search behavior but fail to reject the hypothesis that troopers of different races do not exhibit relative racial prejudice

tax rates and tax evasion evidence from missing imports in china tax evasion by its very nature is difficult to observe we quantify the effects of tax rates on tax evasion by examining the relationship in china between the tariff schedule and the evasion gap which we define as the difference between hong kong s reported exports to china at the product level and china s reported imports from hong kong our results imply that a one percentage point increase in the tax rate is associated with a 3 percent increase in evasion furthermore the evasion gap is negatively correlated with tax rates on closely related products suggesting that evasion takes place partly through misclassification of imports from higher taxed categories to lower taxed ones in addition to underreporting the value of imports

male female disparity in starting pay empirical studies of the earnings of male and female workers persistently reveal a gap that is unexplained by the economic variables in these models this gap has been given two interpretations in the literature one holds that the gap reflects non market forces which distort the equilibrium relation among the wages of competing workers discrimination according to this view prevents female workers from being offered jobs commensurate with their qualifications and crowds them into low productivity occupations 2 the alternative interpretation holds that some substantial portion of the gap is an artifact the result of missing variables biased parameters or measurement error these researchers view the labor market as highly competitive and were it possible to correct for all these statistical problems the measured wage gap would largely vanish 3 this research belongs to the latter category we argue that a portion of the measured gap at least that observed between the earnings of young men and women during their first few years with their employers reflects sex related differences in the shares of investment in firm specific human capital borne by workers of each group moreover these variations in investment levels are freely chosen by women and in no way imply long run deficits in their earning power on the contrary the model predicts steeper earnings profiles of women who undertake this firm specific investment thus women s earnings are predicted eventually to overtake and surpass those of equally qualified men this theory was developed in earlier research by becker and lindsay 2 based on a model of hashimoto 11 12 and extensions by parsons 21 we argued that young women for nondiscriminatory reasons elect to shoulder a larger share of this investment than young men the explanation for this is developed in two stages the first derives the terms under which both male and female workers share the investment with their employers the second argues that female workers will be led by these considerations to bear a larger share workers of both sexes agree to enter into inflexible wage contracts with employers specifying a share of the investment i e a wage deduction from current mvp and a post investment wage the advantage to such contracts lies in the solution to an assymetric information problem the

in search of the glass ceiling gender and earnings growth among u s college graduates in the 1990s gender typical educational choices and the glass ceiling are widely believed to explain why older women earn far less than observably similar men using large panels drawn from the national science foundation s nsf national survey of college graduates and other data representative of u s college graduates from the 1990s the author documents the small role of personal choices and finds evidence contrary to the predictions of both human capital and discrimination models rather than the differential wage growth rates predicted by these models she finds similar average rates of earnings growth for women and men across numerous specifications which suggests that the gender gap in earnings is determined by factors already present early in the career her findings reveal slower earnings growth in only two subsets of women young mothers who experience slower earnings growth during the early career relative to men the same age but then compensate with faster growth later in their careers and women wit

locus of control and job turnover in this paper i investigate how a workeri s locus of control the perception of control over daily events affects job to job and job to nonemployment turnover i find that an increase in internality the degree to which respondents believe that the outcomes of their life events are determined by their own actions versus external factors increases job to job transitions in addition the data reveal that the annual wage growth rate and the wage gains from job to job transitions increase with internality the influence of locus of control on job to nonemployment turnover however is insignificant once the workeri s level of attained education is controlled for

local capture evidence from a central government transfer program in uganda according to official statistics 20 percent of uganda s total public expenditure was spent on education in the mid 1990s most of it on primary education one of the large public programs was a capitation grant to cover schools nonwage expenditures using panel data from a unique survey of primary schools we assess the extent to which the grant actually reached the intended end user schools the survey data reveal that during 1991 1995 the schools on average received only 13 percent of the grants most schools received nothing the bulk of the school grant was captured by local officials and politicians the data also reveal considerable variation in grants received across schools suggesting that rather than being passive recipients of flows from the government schools use their bargaining power to secure greater shares of funding we find that schools in better off communities managed to claim a higher share of their entitlements as a result actual education spending in contrast to budget allocations is regressive similar surveys in other african countries confirm that uganda is not a special case

a strategic model of social and economic networks we study the stability and efficiency of social and economic networks when self interested individuals can form or sever links first for two stylized models we characterize the stable and efficient networks there does not always exist a stable network that is efficient next we show that this tension persists generally to assure that there exists a stable network that is efficient one is forced to allocate resources to nodes that are not responsible for any of the production we characterize one such allocation rule the equal split rule and another rule that arises naturally from bargaining of the players

negotiating environmental agreements under ratification constraints abstract we analyze the impact of ratification constraints on the optimal terms of international environmental agreements ieas for this we combine the literature on ieas with the public choice literature on two level games by also incorporating uncertain preferences of the pivotal voter in the ratification stage we make several important contributions i we contribute to a more realistic modeling of the temporal structure of international agreements ii we show a surprising yet intuitive non monotonic relationship between the optimal commitment level and the variance of ratification decisions iii we identify reasons to expect a larger number of countries to join international negotiations than predicted by most of the coalition formation literature based on a representative agent model ratification constraints thereby can improve the welfare gains from stable international agreements

the price of experience we identify a key role of factor supply driven by demographic changes in shaping several empirical regularities that are a focus of active research in macro and labor economics in particular demographic changes alone can account for the large movements of the return to experience over the last four decades for the differential dynamics of the age premium across education groups emphasized by katz and murphy 1992 for the differential dynamics of the college premium across age groups emphasized by card and lemieux 2001 and for the changes in cross sectional and cohort based life cycle profiles emphasized by kambourov and manovskii 2005 jel d91 e24 i23 j11 j24 j31

interrupted work careers depreciation and restoration of human capital the quantitative effects and even the existence of a human capital depreciation phenomenon have been a subject of controversy in the recent literature prior work however was largely cross sectional and the longitudinal dimension if any was retrospective using longitudinal panel data on married women in nls we have now established that real wages at reentry are indeed lower than at the point of labor force withdrawal and the decline in wages is greater the longer the interruption another striking finding is a relatively rapid growth in wages after the return to work this rapid growth appears to reflect the restoration or repair of previously eroded human capital the phenomenon of depreciation and restoration is also visible in data for immigrants to the united states however while immigrants eventually catch up with and often surpass natives returnees from the nonmarket do not fully restore their earnings potential

experience tenure and wage growth of young black and white men this paper studies the source of differences in wage growth between young black and white workers focusing on terminal high school graduates from the national longitudinal survey of youth we estimate the returns to on the job tenure and general labor market experience using ordinary least squares altonji and shakotko and topel estimators results from all three estimators indicate that returns to general experience for black workers trail those for white workers but that black workers earn equal if not higher returns to tenure than do white workers

the change of tide in political cooperation a limited information model of european integration european integration follows a puzzling stop and go pattern that traditional international reations theories cannot fully explain the predominating paradigms only account for either the achievements or the setbacks of the integration process an information based explanation makes it possible to move beyond structural accounts provided by realist and functionalist scholarship such an approach yields solid micro level foundations of international bargaining and focuses on leaders use of threats in negotiations about regional cooperation situations involving governments agreeing on the necessity of further integration but disagreeing about its level create room for strategic manipulation of information asymmetries this type of uncertainty stems from the manipulator s information and control advantages concerning domestic costs the analysis of different summit meetings demonstrates the empirical relevance of such maneuvers for the dynamics of european integration

a longitudinal analysis of white women s wages according to human capital theory women s work participation decisions will strongly affect their wages and wage growth we test human capital predictions about how labor force withdrawals both past and prospective part time work experience and working in male rather than in female jobs affect wages and wage growth for white women we do this by estimating a wage change model for the years 1967 1979 for a national sample of white women we find that wages drop immediately following withdrawals but that this is followed by a rapid wage growth so that the net loss in wages from dropping out of the labor force is small we further find that wage growth is not significantly lower in female than in male jobs but that part time work experience does not lead to significant wage growth in either male or female jobs

early career work experience and gender wage differentials we estimate a wage model that includes an array of variables measuring the fraction of time worked during each year of the career this array fully characterizes past employment experience regardless of how sporadic it has been our model yields substantially higher estimated returns to experience and lower returns to tenure than do models that measure experience cumulatively and use the standard quadratic functional form we find that the data reject the standard model but fail to reject our model furthermore we find that 12 of the male female wage gap is due to differences in the timing of work experience

the effects of interrupted schooling on wages data from the national longitudinal survey of youth reveal that 35 percent of white men who leave school between 1979 and 1988 return to school by 1989 this paper examines the wage effects of these nontraditional enrollment patterns i estimate a wage model which allows individuals to follow a different wage path before and after their reenrollment and an alternative model which does not account for school and work discontinuities i find that young men who delay their schooling receive wage boosts that are smaller than those received by their continuously schooled counterparts wage models that fail to account for delayed schooling tend to understate the returns to schooling received prior to the start of the career

the uncertainty effect when a risky prospect is valued less than its worst possible outcome expected utility theory prospect theory and most other models of risky choice are based on the fundamental premise that individuals choose among risky prospects by balancing the value of the possible consequences these models therefore require that the value of a risky prospect lie between the value of that prospect s highest and lowest outcome although this requirement seems essential for any theory of risky decision making we document a violation of this condition in which individuals value a risky prospect less than its worst possible realization this demonstration which we term the uncertainty effect draws from more than 1000 experimental participants and includes hypothetical and real pricing and choice tasks as well as field experiments in real markets with financial incentives our results suggest that there are choice situations in which decision makers discount lotteries for uncertainty in a manner that cannot be accommodated by standard models of risky choice from the time of bernoulli on it has been common to argue that a individuals tend to display aversion to the taking of risks and b that risk aversion in turn is an explanation for many observed phenomena in the economic world arrow 1971 p 90

trends in earnings differentials by gender 1971 1981 this paper clarifies trends in relative earnings by sex over the decade 1971 1981 and decomposes these trends to determine which factors contributed to a decline and which to an increase our analyses are based upon data from the annual demographic files of the current population survey for 1972 and 1982 this study is unique in that it estimates earnings functions in each year which are corrected for selectivity bias it is found that such a correction markedly raises the progress of white women relative to men among blacks the impact of the selectivity bias correction was to substantially lower the relative earnings increase of women however the coefficients on the selectivity variable were not significant the findings suggest declining sex role specialization and discrimination as conventionally measured over the decade on the other hand contrary to expectations the total effect of variables reflecting the sex composition of the individuals occupation worked to widen the sex differential over the period the sex differential was also adversely affected by a decline in the relative return to education especially for whites authors modified

the gender wage gap and the role of reservation wages new evidence for unemployed workers this paper examines the importance of differences in reservation wages for the gender wage gap based on two waves of rich survey data for a sample of newly unemployed individuals in germany we perform a decomposition analysis including measures for reservation wages detailed information on education socio demographics labor market history as well as personality traits in order to address the potential endogeneity of reservation wages we exploit a generated instrumental variable strategy that relies on heteroscedasticity of the error terms our findings indicate that the gender wage gap becomes small and statistically insignificant once we control for reservation wages moreover we perform a subgroup analysis that provides valuable insights about the importance of potentially unobserved characteristics that affect reservation wages and realized wages simultaneously reasons for differences in reservation wages could arise from productivity differences the fact that women anticipate discrimination and different unobserved traits or preferences

the simple economics of extortion evidence from trucking in aceh this paper tests whether the behavior of corrupt officials is consistent with standard industrial organization theory we designed a study in which surveyors accompanied indonesian truck drivers on 304 trips during which they observed over 6 000 illegal payments to police soldiers and weigh station attendants using plausibly exogenous changes in the number of checkpoints we show that market structure affects the level of illegal payments we further show that corrupt officials use complex pricing schemes including third degree price discrimination and a menu of two part tariffs our findings illustrate the importance of considering the market structure for bribes when designing anticorruption policy

the racial wage gap the importance of labor force attachment differences across black mexican and white men labor market attachment differs significantly across young black mexican and white men although it has long been agreed that potential experience is a poor proxy for actual experience for women many view it as an acceptable approximation for men using the nlsy this paper documents the substantial difference between potential and actual experience for both black and mexican men we show that the fraction of the black white and mexican white wage gaps that are explained by differences in potential experience are quite different from the fraction of the racial wage gaps that are explained by actual real experience differences

monitoring motivation and management the determinants of opportunistic behavior in a field experiment economic models of incentives in employment relationships are based on a specific theory of motivation employees are rational cheaters who anticipate the consequences of their actions and shirk when the marginal benefits exceed costs we investigate the rational cheater model by observing how experimentally induced variation in monitoring of telephone call center employees influences opportunism a significant fraction of employees behave as the rational cheater model predicts a substantial proportion of employees however do not respond to manipulations in the monitoring rate this heterogeneity is related to variation in employee assessments of their general treatment by the employer jel d2 j2 l2 l8 m12

winning isn t everything corruption in sumo wrestling although the theoretical literature on corruption is well developed empirical work in this area has lagged because it has proven difficult to isolate corrupt behavior in the data in this paper we look for evidence of corruption in an unlikely place the highest echelons of japanese sumo wrestling this paper provides strong statistical evidence documenting match rigging in sumo wrestling a non linearity in the incentive structure of promotion leads to gains from trade between wrestlers on the margin for achieving a winning record and their opponents we show that wrestlers win a disproportionate share of the matches when they are on the margin increased effort can not explain the findings winning on the bubble is more frequent when the two competitors have met often in the past success on the bubble tends to rise over the course of a wrestler s career but declines in his last year consistent with the game theoretic predictions wrestlers who are victorious when on the bubble lose more frequently than would be expected the next time they meet that opponent suggesting that part of the payment for throwing a match is future payment in kind systematic differences across wrestling stables suggest that the stables play a role in facilitating the corruption in times of increased media scrutiny the match rigging disappears this abstract was borrowed from another version of this item

a model of electoral competition with incomplete information a model of two candidate electoral competition is developed in which voters are uncertain about the policy either candidate would implement if elected candidates simultaneously announce policy positions from which voters attempt to infer the true positions the candidates would adopt announcing a position different from the true position is costly to the winning candidate with these costs increasing as the difference between the true policy and the announced policy increases a refinement of the sequential equilibrium concept is used to describe the behavior of candidates and voters

domestic institutions and international bargaining the role of agent veto in two level games putnam s 1988 conjecture that negotiators can benefit from their domestic constraints implies that they may want to impose domestic constraints on themselves by granting veto power to an agent i show that a negotiator s decision to employ an agent as veto player depends on the kinds of information available to the foreign country and the alignment of preferences between the negotiator and the agent when the foreign country has incomplete information about the negotiator s preferences and the negotiator has preferences too divergent from those of the agent the negotiator will not give veto power to the agent however this applies only to an agent with extreme preferences and a surprisingly large number of agent types will receive veto power the attractiveness of the agent veto to the negotiator is in part due to its informational effect by granting veto power to an agent the negotiator can transmit more information to the foreign country and capture informational gains that would be lost in the absence of the agent veto

urban effects on participation and wages are there gender differences abstract this paper estimates participation and wage equations using panel data from the united kingdom to explore gender differences in urban wage and participation premiums the results suggest a small but economically significant urban participation premium for women but none for men results from the wage estimations suggest that after controlling for sample selectivity observed and unobserved heterogeneity the urban premium is larger for women this wage premium is also larger for married or cohabiting women relative to others there is also evidence of higher urban returns to experience for men and lower urban wage depreciation for both men and women

fighting corruption to improve schooling evidence from a newspaper campaign in uganda what are the most effective ways to increase primary school enrollment and student learning we argue that innovations in governance of social services may yield the highest return since social service delivery in developing countries is often plagued by inefficiencies and corruption we illustrate this by using data from an unusual policy experiment a newspaper campaign in uganda aimed at reducing capture of public funds by providing schools parents with information to monitor local officials handling of a large education grant program the campaign was highly successful and the reduction in capture had a positive effect on enrollment and student learning jel d73 i22 o12

subscription mechanisms for network formation we analyze a model of network formation where the costs of forming links are publicly known but an individual s benefits are not known to the social planner the objective is to design a mechanism which not only ensures that an efficient network always forms in equilibrium but also ensures that the resulting net payoffs to the agents are equitable we propose two mechanisms towards this end in the first agents announce sequentially the set of players with whom they wish to form links and a cost contribution we show that all subgame perfect equilibria of this game result in the formation of an efficient network but the resulting net payoffs are asymmetric the second mechanism corrects this asymmetry through a two stage variant of the first mechanism we also discuss an extension of the basic model to cover the case of directed graphs and give conditions under which the proposed mechanisms are immune to deviations by coalitions

carrots sticks and broken windows abstract this paper investigates the effect of economic conditions carrots and sanctions sticks on murder assault robbery burglary motor vehicle theft grand larceny and rape in new york city using monthly time series data spanning 1974 99 carrots are measured by the unemployment rate and the real minimum wage sticks are measured by the number of felony arrests size of the police force and number of new york city residents in prison in addition the paper tests the validity of the broken windows hypothesis consistent with its implementation by the new york police department we use misdemeanor arrests as a measure of broken windows policing the broken windows hypothesis has validity in the case of robbery motor vehicle theft and grand larceny while both economic and deterrence variables are important in explaining the decline in crime the contribution of deterrence measures is larger than those of economic variables

electoral cycles and international policy cooperation abstract this paper analyzes the interaction between domestic politics and international policy coope ration as a two level repeated prisoners dilemma at the domestic level two party competition generates an electoral cycle in monetary growth inflation and real output at the international level the policymakers desire to promote domestic expansion by depreciating the currency gives rise to an inflationary bias in monetary growth a move towards international cooperation reduces the inflationary bias but may increase the amplitude of the electoral cycle moreover international cooperation may not be desirable for one of the domestic parties nevertheless domestic and international cooperation may be jointly sustained by the credible threat of a reversion to the regime under which the destabilizing effect of domestic politics is at a maximum

strategic delay in bargaining this paper analyses a bargaining model with incomplete information in which the time between offers is an endogenous strategic variable we find equilibria involving a delay to agreement that is due to the use of strategic time delay by bargainers to signal their relative strength under some specifications of the parameters delay is present in the unique sequential equilibrium whose beliefs satisfy one intuitive restriction this delay does not vanish as the minimal time between offers becomes small

reassessing the gender wage gap in madagascar does labor force attachment really matter abstract in the labor economics literature it has been argued that differences in labor force attachment across gender are important to explain the extent of the gender wage gap however measures of women s work experience are particularly prone to errors given discontinuity in labor market participation using proxy measures such as potential experience may lead to biased estimates of the returns to human capital such biases cannot be ignored since these returns are used in the standard decomposition techniques to measure the extent of gender based wage discrimination by matching two original surveys conducted in madagascar in 1998 a labor force survey and a biographical survey we built a unique data set that enabled us to combine the original information gathered from each of them particularly the earnings from current employment and the entire professional trajectories our results lead to a reassessment of the returns to human capital as potential experience always exceeds actual experience for b

is there a causal effect of working part time on current and future wages in this paper i study the causal effects of part time work on current and future wages to estimate these effects i use a random effects model with a wage equation capturing the employment history and a dynamic multinomial probit component for the choice of employment status exclusion restrictions from the institutional context are exploited to support identification the results suggest that working part time with few hours has a large causal effect on current wages but more extensive part time work does not reduce current wages however both types of part time work lead to negative long term wage effects

a quantitative theory of the gender gap in wages abstract this paper measures how much of the gender wage gap over the life cycle is due to the fact that working hours are lower for women than for men we build a quantitative theory of fertility labor supply and human capital accumulation decisions to measure gender differences in human capital investments over the life cycle we assume that there are no gender differences in the human capital technology and calibrate this technology using wage age profiles of men the calibration of females assumes that children involves a forced reduction in hours of work that falls on females rather than on males and that there is an exogenous gender gap in hours of work we find that our theory accounts for all of the increase in the gender wage gap over the life cycle in the nlsy79 data the impact of children on the labor supply of females accounts for 56 and 45 of the increase in the gender wage gap over the life cycle among non college and college females while the rest is due to the exogenous gender differences in hours of work

welfare reform returns to experience and wages using reservation wages to account for sample selection bias abstract one rationale for work focused welfare reform was human capital theory work today should raise experience tomorrow which should raise future wage offers and reduce welfare dependency yet few studies have estimated the effect of welfare reform on wages i approach the problem using a novel sample selection estimator based on reservation wage data reservation wages solve the selection problem using bivariate censored regression methods without the need for exclusion restrictions whereas ols and conventional sample selection estimates suggest that reform had little effect on wages the reservation wage adjusted estimates suggest that florida s welfare reform experiment raised wages by about 4

pay and productivity differences between male and female veterinarians the author uses data from annual wage surveys conducted in 1994 and 1995 by medical economics research group to study differences in pay and productivity between male and female veterinarians in the wage salary sector the gender gap in average earnings was 15 when controls for various observable characteristics are added to the analysis the earnings gap narrows to 9 based on the most conservative estimates using unique revenue production measures in an analysis holding other factors constant the author finds that women s productivity was not statistically different from men s together the findings of gender differences in earnings but not in productivity are consistent with the presence of wage discrimination but the author explores other possible explanations as well

sex related wage differentials and women s interrupted labor careers the chicken or the egg wage differentials between men and women are often attributed to differences in on the job training the lower investment of women being explained by their plans to interrupt their careers for family reasons career interruptions however are often explained by low wages to trace this interrelationship i adopt a simultaneous equations approach trying to explain wages planned separations on the job training and the skill intensity of the job simultaneously skill intensity is found to be a key variable in the explanation of the wage differential traditional theory is hard pressed to explain the sex related differences in this variable

allocating value among farsighted players in network formation we study the stability of networks when players are farsighted and allocations are determined endogenously the set of strongly efficient networks is the unique von neumann morgenstern farsightedly stable set with bargaining if the value function is anonymous component additive and top convex and the allocation rule is anonymous and component efficient moreover the componentwise egalitarian allocation rule emerges endogenously

forming efficient networks abstract we suggest a simple sequential mechanism whose subgame perfect equilibria give rise to efficient networks moreover the payoffs received by the agents coincide with their shapley value in an appropriately defined cooperative game

a one stage model of link formation and payoff division abstract in this paper we introduce a strategic form model in which cooperation structures and divisions of the payoffs are determined simultaneously we analyze the cooperation structures and payoff divisions that result according to nash equilibria strong nash equilibria and coalition proof nash equilibria we find that no cycle will be formed if a player claims a positive amount for the formation of one of its links and that a player does not necessarily profit from a central position in a cooperation structure journal of economic literature classification numbers c71 c72

crime and social interactions the high variance of crime rates across time and space is one of the oldest puzzles in the social sciences this variance appears too high to be explained by changes in the exogenous costs and benefits of crime we present a model where social interactions create enough covariance across individuals to explain the high cross city variance of crime rates this model provides an index of social interactions which suggests that the amount of social interactions is highest in petty crimes moderate in more serious crimes and almost negligible in murder and rape

obtaining a driver s license in india an experimental approach to studying corruption we conduct two experiments to understand the process of obtaining a driver s license in india in the first experiment we randomly assign license candidates to one of three groups bonus offered a financial reward if they could obtain their license fast lesson offered free driving lessons upfront and control the control group alone illustrates bureaucratic failures 71 of the license getters in that group avoided the mandated driving test and 62 failed a surprise driving test the system responds to private needs there are more license getters in the bonus group but at a social cost there are more license getters who cannot drive in the bonus group the system however also appears to respond to social considerations as there are more license getters in the lesson group large extra legal payments are made by license getters those in the control group pay 2 5 times the official fee more of these extra legal payments take place in the bonus group surprisingly these extra legal payments are not direct bribes to bureaucrats but instead payments to agents in the second experiment we perform an audit study to better understand the role of agents the audit shows that agents can provide licenses to individuals even if they cannot drive but the audit also shows that agents cannot as easily circumvent all other rules we argue that our findings are most consistent with agents being the channel for corruption in this system we also report some suggestive evidence that bureaucrats create red tape possibly to induce more license candidates to use agents

did iraq cheat the united nations underpricing bribes and the oil for food program from 1997 through 2003 the un oil for food program allowed iraq to export oil for humanitarian supplies we hypothesize that iraq deliberately set the price of its oil below market prices to solicit bribes from oil buyers by comparing the price gap between iraqi oil and its close substitutes during the program to the gap prior to the program we nd evidence of signican t underpricing our central estimate suggests that iraq collected 1 3 billion in bribes from underpricing its oil or 2 percent of oil revenues underpricing is higher during periods of high volatility in oil markets when detection is more dicult but declines after the un limited iraq s ability to set the price of its oil

employment motherhood and school continuation decisions of young white black and hispanic women we examine the empirical relationship between early employment activity and school continuation decisions for young american women using a dynamic sequential discrete choice framework that estimates schooling labor supply and birth decisions jointly controlling for unobserved heterogeneity and the endogeneity of these life cycle decisions that the rate of school withdrawal increases as work intensity rises helps explain the higher departure rates of hispanic girls from secondary school and the premature departure of young black women from college the disturbing implication is that youth employment induces long run wage stagnation for early school leavers and potentially increases race and ethnic inequities

youth labor markets in the united states shopping around vs staying put the need for school to work programs or other means of increasing early job market stability is predicated on the view that the chaotic nature of youth labor markets in the united states is costly because workers drift from one job to another without developing skills behavior or other characteristics that in turn lead to higher adult earnings however there is also ample evidence that workers receive positive returns to job shopping this paper asks whether youths in unstable jobs early in their careers suffer adverse labor market consequences as adults its specific contribution is to account for the endogenous determination of early job stability and adult wages as outcomes of a job search job shopping process labor market conditions in the early years in the labor market are used as instrumental variables for the job stability experienced during those years the instrumental variables estimates generally point to substantial positive effects of early job stability on adult wages in contrast to

vocational training and gender wages and occupational mobility among young workers this paper investigates the relationship between the gender wage gap the choice of training occupation and occupational mobility we use longitudinal data for young workers with apprenticeship training in west germany workers make occupational career choices early during their careers and women and men pursue very different occupational careers we reconsider whether through occupational segregation women are locked in low wage careers kunze 2005 or whether they can move up to higher wage paths through mobility we furthermore investigate whether patterns have changed across cohorts during the period 1975 and 2001 and whether effects vary across the distribution the main results are first while there exists a persistent gender wage gap over experience the gap has decreased over time second in the lower part of the wage distribution the gap is highest and it increases with experience third occupational mobility is lower for women than for men and the wage gains due to occupational mobility are higher for men than for women especially in the lower part of the wage distribution we conclude that occupational mobility has reduced the gender wage gap but lock in effects are still stronger for women compared to men

a letter to the editor on wage bargaining abstract the rubinstein perfect information alternating offers bargaining model is problematic when applied to wage negotiations a strike or any other industrial action is not an automatic consequence of a delay in reaching an agreement because production can continue normally also when negotiations take place this paper extends the rubinstein model to incorporate the choice of calling a strike and it is shown that in this model there is no longer a unique subgame perfect equilibrium and that strikes with a length in real time can occur in equilibrium

perverse incentives labor market regulation and performance in the public sector we test the link between labor market regulations and job performance in the public sector using a novel outcome variable namely the number of days it takes the postal service to return letters sent to nonexistent foreign addresses a measure that we argue is an excellent proxy for job performance we find a positive and statistically significant link between these two variables regardless of the labor regulation measure employed changes in specification and even unlikely endogeneity considerations which suggest that this finding may be causal

an investigation into sexual orientation discrimination as an explanation for wage differences this study explores the effects of sexual orientation on earnings it is found that ceteris paribus men living with male partners tend to earn less than other men and women living with female partners tend to earn more than other women these earnings differentials tend to vary by region they also vary by education and occupation for men and with the presence of minor children for women in addition the age earnings profiles of women living with female partners tend to be higher flatter and less concave than those of other women

the dynamics of the two level bargaining game the 1988 brazilian debt negotiations n this study we examine the case of the brazilian debt rescheduling lagreement of 1988 as a two level game in which each of the two main negotiators the brazilian state and the international bank advisory committee must satisfy its own constituents while trying to negotiate an international agreement the literature on the politics of debt and adjustment tends to look either at the domestic politics of stabilization and adjustment or at collective action at the level of the international regime we argue however that the interaction between the domestic and international levels must be understood in order to explain the outcomes of international debt negotiations drawing on the concept of the two level game in international politics suggested by robert putnam

interfirm mobility wages and the returns to seniority and experience in the united states in this paper we expand on the seminal work of altonji and shakotko 1987 and topel 1991 and reinvestigate the returns to seniority in the united states we begin with the same wage equation as in previous studies we extend the model of hyslop 1999 and explicitly model the participation employment and inter firm mobility decisions which in turn define the individual s experience and seniority we introduce into the wage equation a summary of the workers entire career path the three equation system is estimated simultaneously using data from the panel study of income dynamics psid we find that for each of the three education groups studied the returns to seniority are larger than those previously found in the literature

involuntary defection in two level games ratification failures are prevalent in international relations but due to the assumption of unitary actors in international relations theory theoretical analysis has been underdeveloped in formalizing putnam s metaphor of two level games this article shows that incomplete information about the preferences of domestic actors is crucial for understanding ratification failures furthermore institutional mechanisms affect bargaining outcomes through their impact on information revelation in particular it is found that two sided constraints lead to relatively equitable bargaining outcomes and that renegotiation and pre negotiation poll taking can induce strategic voting by domestic constituents thereby exacerbating domestic constraints

the role of wages and auditing during a crackdown on corruption in the city of buenos aires abstract we study the prices paid for basic inputs during a crackdown on corruption in the public hospitals of the city of buenos aires argentina during 1996 97 we find a well defined negative effect on the measures used to capture corruption prices paid by hospitals for basic homogeneous inputs decrease by 15 percent during the first 9 months of the crackdown after this period prices increase but they are still 10 percent lower than those prevailing before the crackdown relative to the precrackdown period higher wages play no role in inducing lower input prices when audit intensity can be expected to be maximal during the first phase of the crackdown but have a negative and well defined effect when audit intensity takes intermediate levels the last phase of the crackdown controlling for fixed effects we find that the wage elasticity of input prices exceeds 20 these results are consistent with the standard model of bribes of gary becker and george stigler

bargaining and strikes strikes are generally regarded as an important economic phenomenon and yet good theoretical explanations of them are hard to come by the difficulty is to understand why rational parties should resort to a wasteful mechanism as a way of distributing the gains from trade why could not both parties be made better off by moving to the final distribution of surplus immediately or if it is uncertain to its certainty equivalent and sharing the benefits from increased production

bargaining foundations of shapley value1 a transferable utility economy in which each agent holds a resource which can be used in combination with the resources of other agents to generate value according to the characteristic function v is studied using a dynamic model of bargaining the main theorem establishes that the payoffs associated with efficient equilibria converge to the agents shapley values as the time between periods of the dynamic game goes to zero in addition it is demonstrated that an efficient equilibrium exists and is unique when an additivity condition is satisfied to demonstrate the sensitivity of the solution to the institutional detail we modify the model to allow for partnerships and show that the shapley value is no longer achieved

are women more risk averse we find that single women exhibit relatively more risk aversion in financial decision making than single men using u s sample data we examine household holdings of risky assets to determine whether there are gender differences in financial risk taking as wealth increases the proportion of wealth held as risky assets is estimated to increase by a smaller amount for single women than for single men gender differences in financial risk taking are also influenced by age race and number of children greater financial risk aversion may provide an explanation for women s lower levels of wealth compared with men s jel j16 d81 g11

using electoral cycles in police hiring to estimate the effect of police on crime comment previous empirical studies have uncovered little evidence that police reduce crime possibly due to simultaneity problems this paper uses the timing of mayoral and gubernatorial elections as an instrumental variable to identify a causal effect of police on crime increases in the size of police forces are shown to be disproportionately concentrated in mayoral and gubernatorial election years increases in police are shown to substantially reduce violent crime but have a smaller impact on property crime the null hypothesis that the marginal social benefit of reduced crime equals the costs of hiring additional police cannot be rejected

a meta analysis of the international gender wage gap abstract since the early 1970s a number of authors have calculated gender wage differentials between women and men of equal productivity this meta study provides a new quantitative review of this vast amount of empirical literature on gender wage differentials as it concerns not only differences in methodology data and time periods but also different countries we place particular emphasis on a proper consideration of the quality of the underlying study which is done by a weighting with quality indicators the results show that data restrictions i e the limitation of the analysis to new entrants never marrieds or one narrow occupation only have the biggest impact on the resulting gender wage gap moreover we are able to show what effect a misspecification of the underlying wage equation like the frequent use of potential experience has on the calculated gender wage gap over time raw wage differentials worldwide have fallen substantially however most of this decrease is due to better labor market endowments of females

the usefulness of predicted values for prior work experience in analyzing labor market outcomes for women this paper proposes an improved way of treating experience in estimating wage equations for women when measures of actual experience are lacking it shows that using a predicted value for experience from occupation specific equations estimated on another data set containing actual experience is preferable to using either potential experience time since school leaving or predicted experience without taking account of the woman s occupation results also show that the use of potential experience may bias the estimated impact offactors such as race and schooling on women s wages

lost in the mail a field experiment on crime crime in the mail sector can hamper the development of elec tronic markets we use a field experiment to detect crime and measure its differential impacts we subtly and realistically manipulate the content and information available in mail sent to households and detect high levels of shirking and stealing eighteen percent of the mail never arrived at its des tination and even more was lost if there was even a slight hint of something additional inside the envelope our study demonstrates that privatization has been unable to extricate moral hazard and that crime is strategic and not equally distributed across the population

job mobility and wage trajectories for men and women in the united states young american workers typically change employers many times in the course of establishing their careers this article examines the consequences of this mobility for wage inequalities between and among men and women using multilevel modeling and data from the 1979 to 2002 waves of the national longitudinal survey of youth 1979 nlsy79 i disentangle the various ways in which mobility shapes the trajectories of wage growth findings caution against accepting the adequacy of prevalent economic models of mobility models that tend to isolate individual workers moves from broader patterns of work history and that treat mobility as a decontextualized individual choice although workers who frequently switch employers generally end up earning less than their more stable counterparts the type timing and relative level of changes strongly affect the ultimate wage differential differences in the degree of men s and women s labor force attachment and family circumstances are also influential workers who are l

empirical age earnings profiles the human capital earnings function in which earnings are expressed as a quadratic in potential experience is probably the most widely accepted empirical specification in economics in spite of its widespread acceptance the human capital earnings function provides a very poor approximation of the true empirical relationship between earnings and experience the standard formulation understates early career earnings growth by about 30 50 and overstates midcareer growth by 20 50 however simple alternative specifications that fit the data are available

from unanimity to consensus an analysis of the negotiations at the eu s constitutional convention disputes filed at the world trade organization wto are attracting a growing number of third parties most observers argue that their participation influences the institution s rulings the authors argue that third parties undermine pretrial negotiations their influence on rulings is conditioned by this selection effect they test their hypotheses along with the conventional wisdom using a data set of wto disputes initiated through 2002 consistent with the authors argument they find that third party participation lowers the prospects for early settlement controlling for this selection effect the evidence also suggests that third party support increases the chances of a legal victory at the wto

two level games and bargaining outcomes why gaiatsu succeeds in japan in some cases but not others one of the strengths of robert putnam s two level bargaining game model is its ability to capture how international negotiations make it possible for negotiators to pursue synergistic strategies aimed at improving their prospects for a favorable deal by reshaping politics in both their own and their counterparts domestic arenas while reaffirming the utility of this approach this article argues that putnam describes only some of the synergistic strategies available to negotiators in addition to reverberation and synergistic linkage a negotiator can also reshape politics in his or her counterpart s domestic arena in two other ways 1 by transforming decision making in ways that expand elite participation and bring the weight of public opinion to bear on policies that were previously dictated by small groups of privileged domestic actors and 2 by influencing the way in which policy alternatives are considered in the decisionmaking process through an examination of the structural impediments initiative a set of negotiations through which the united states applied a great deal of foreign pressure gaiaisu on japan the article makes the case for the above modifications to the putnam model and argues that participation expansion strategies are most likely to be successful when involvement in decision making before foreign intervention is limited and latent support for foreign demands exists outside the privileged elite while alternative specification is most likely to work when opportunities exist to link favored policy proposals to already recognized domestic problems

uncertainty and ratification failure i study a game where two agents bargain on an agreement to replace the status quo for their agreement to come into effect they need the approval of a third agent the preferences of this third agent is private information but there is communication among agents i study this game in the context of international agreements to provide an explanation for involuntary ratification failures i show that under certain assumptions the informational deficiency is incurable due to incentives to misrepresent preferences and that a parliament whose majority is more hawkish than their executive prefers the executive to be risk averse

open versus closed door negotiations we examine a noncooperative bargaining between two agents one of whom agent 1 represents a constituency under closed door bargaining constituents must approve the final bargaining agreement in the open door case constituents may also terminate bargaining after intermediate offers have been made and rejected a learning effect and a termination effect arise in open door bargaining the former increases and the latter decreases the payoff to agent 2 from rejecting offers the termination effect dominates making agent 2 less likely to reject offers and hence making agent 1 more aggressive in the open door case
