sons daughters and parental behaviour the prevalence of son preference and its implications for family behaviour in developing countries have received a great deal of scholarly attention but child gender bias is believed to be empirically unimportant in wealthy non traditional societies studies by sociologists and psychologists during the past 30 years however have documented consistent discrepancies between the behaviour of parents of sons and parents of daughters boys tend to increase marital stability and marital satisfaction relative to girls and fathers spend more time with and are more involved with sons than daughters in recent years economists have begun to contribute to the child gender literature re examining the effects of sons and daughters on family structure and parental involvement with larger samples and greater concern for possible sources of selection bias other economic outcomes such as market work and earnings have also been studied and some investigators have exploited the randomness of child gender as a source of exogenous variation in parental behaviour in general recent results suggest that child gender does affect family stability and the time allocation of parents but it is not clear whether these responses reflect parental preferences for boys rather than girls or differences in the constraints parents face copyright 2005 oxford university press

price taking equilibrium in economies with multiple memberships in clubs and unbounded club sizes abstract we model an economy with clubs or jurisdictions where individuals may belong to multiple clubs and where clubs sizes are arbitrary clubs may be restricted to consist of only one or two persons or as large as the entire economy or anything in between notions of price taking equilibrium and the core both with communication costs are introduced these notions take into account that there is a small communication cost of deviating from a given outcome we demonstrate that given communication costs for all sufficiently large economies the core is nonempty and the set of price taking equilibrium outcomes is equivalent to the core

refinancing profitability and capital structure abstract we revisit the well established puzzle that leverage is negatively correlated with measures of profitability in contrast we find that at times when firms are at or close to their optimal level of leverage the cross sectional correlation between profitability and leverage is positive at other times it is negative these results are consistent with dynamic trade off models in which infrequent capital structure rebalancing is optimal the time series of market leverage and profitability in the quarters prior to rebalancing events match the patterns predicted by these models our results are not driven by investment layouts market timing payout or mechanical mean reversion of leverage

understanding the family gap in pay for women with children as the gender gap in pay between women and men has been narrowing the family gap in pay between mothers and nonmothers has been widening one reason may be the institutional structure in the united states which has emphasized equal pay and opportunity policies but not family policies in contrast to other countries that have implemented both the authors now have evidence on the links between one such family policy and women s pay recent research suggests that maternity leave coverage by raising women s retention after childbirth also raises women s levels of work experience job tenure and pay

the debt equity choice when firms adjust their capital structures they tend to move toward a target debt ratio that is consistent with theories based on tradeoffs between the costs and benefits of debt in contrast to previous empirical work out tests explicitly account for the fact that firms may face impediments to movements toward their target ratio and that the target ratio may change over time as the firm s profitability and stock price change a separate analysis of the size of the issue and repurchase transactions suggests that the deviation between the actual and the target ratios plays a more important role in the repurchase decision than in the issuance decision

accounting conservatism and firm investment efficiency abstract we argue that conservatism improves investment efficiency in particular we predict that it resolves debt equity conflicts facilitating a firm s access to debt financing and limiting underinvestment this permits the financing of prudent investments that otherwise might not be pursued our empirical results confirm these predictions we find that more conservative firms invest more and issue more debt in settings prone to underinvestment and that these effects are more pronounced in firms characterized by greater information asymmetries we also find that conservatism is associated with reduced overinvestment even for opaque investments such as research and development

are observed capital structures determined by equity market timing contrary to baker and wurgler 2002 i find that the importance of historical average market to book ratios in leverage regressions is not due to past equity market timing al though equity transactions may be timed to equity market conditions they do not have sig nificant long lasting effects on capital structure debt transactions exhibit timing patterns that are unlikely to induce a negative relation between market to book ratios and leverage i also find that historical average market to book ratios have significant effects on current financing and investment decisions implying that they contain information about growth opportunities not captured by current market to book ratios

gender and ethnicity married immigrants in britain in this paper we investigate the economic activity of married or cohabiting female immigrants in britain we distinguish between two immigrant groups foreign born females who belong to an ethnic minority group and their husbands and foreign born white females and their husbands we compare these to native born white women and their husbands our analysis deviates from the usual mean analysis and investigates employment hours worked and earnings for males and females as well as their combined family earnings along the distribution of husbands economic potential we analyse the extent to which economic disadvantage may be reinforced at the household level and investigate the extent to which it can be explained by differences in observable characteristics we find that white female immigrants and their husbands have an overall advantage in earnings over white native born both individually and at the household level minority immigrants do less well in particular at the lower end of the husbands economic potential distribution this is mainly due to the low employment of both genders which leads to a disadvantage in earnings intensified at the household level only part of this differential can be explained by observable characteristics

gender and student achievement in english schools in the uk there is a marked gender gap in the educational attainment of boys and girls at the end of compulsory education 10 per cent fewer boys achieve 5 or more good gcses this gap is by no means confined to gcse it is evident at all key stages furthermore some indicators suggest that the gap has widened over time in this paper we document the evolution of the gender gap at various stages of compulsory education in england we consider the importance of some possible explanations for the gender gap in particular factors that may explain the observed changes over time analysis of this issue is important in the context of research on the gender wage gap however it also raises policy relevant issues in relation to whether changes in the school system can effect a change in the gender gap in educational achievement we find that it is in secondary school rather than primary school where the gender gap has widened most noticeably over time controlling for attainment at the end of primary school makes very little difference to the measured gender gap at age 16 we consider the potential role of school based factors school inputs teaching practice and the examination system we show that the average gender differential cannot be explained by factors that vary across schools i e it cannot be attributed to heterogeneity across schools in how they use inputs however this does not mean that teachers cannot influence the gender gap in attainment we show that the introduction of the literacy hour and numeracy hour in primary schools made a difference to the gender gap in english and maths respectively at key stage 2 however these strategies are too recent to have made an impact on the gender gap observed in secondary school the timing of the emergence of the gender gap in secondary school coincides with the change in examination system from o levels to gcses we argue that the importance of coursework in the gcse examination is likely to be a key explanation for the emergence of the gender gap at age 16 another very important explanation may be a gender differential in skills that are taught and tested in different types of system as well as the mode of assessment we also consider the potential role of social and economic changes that would influence the relative achievement of boys and girls at age 16 however the most compelling explanation to explain the specific timing of the gender gap at this age in the england comes from the change in examination system taken together with the evidence on the literacy and numeracy strategies this shows that education policy can most definitely have an impact on the gender gap in achievement whether this is intended or not

determinants of target capital structure the case of dual debt and equity issues abstract we examine whether market and operating performance affect corporate financing behavior because they are related to target leverage our focus on firms that issue both debt and equity enhances our ability to draw inferences consistent with dynamic trade off theories dual issuers offset the deviation from the target resulting from accumulation of earnings and losses our results also imply that high market to book firms have low target debt ratios on the other hand consistent with market timing high stock returns increase the probability of equity issuance but have no effect on target leverage

gender role attitudes and the labour market outcomes of women across oecd countries this paper uses data from the world value surveys 1990 1995 1999 to investigate the impact of gender role attitudes and work values on women s labour market outcomes across 25 oecd countries anti egalitarian views are found to display the strongest negative association with female employment rates and the gender pay gap these views are however softening among recent cohorts on the other hand perceptions of women s role as homemakers which are likely formed in youth and linked to religious ideology are more persistent over time they could be implicated in the recent slowdown of the gender convergence in pay finally the unavoidable clash between family values and egalitarian views that takes the form of an inner conflict for many women the so called mother s guilt is another obstacle in the path towards greater gender equality in the labour market copyright 2005 oxford university press

the assessment gender and the life cycle this assessment is an introduction to the oxford review of economic policy s issue on gender and the life cycle it sets the stage by providing background information on various dimensions of gender differences pointing out differences across countries as well as over time and relates this evidence to the papers that follow it further briefly reviews the articles in the issue and puts them into context

debt and the marginal tax rate abstract do taxes affect corporate debt policy this paper tests whether the incremental use of debt is positively related to simulated firm specific marginal tax rates that account for net operating losses investment tax credits and the alternative minimum tax the simulated marginal tax rates exhibit substantial variation due to the dynamics of the tax code tax regime shifts business cycle effects and the progressive nature of the statutory tax schedule using annual data from more than 10 000 firms for the years 1980 1992 i provide evidence which indicates that high tax rate firms issue more debt than their low tax rate counterparts

on the existence of an optimal capital structure theory and evidence one of the most contentious issues in the theory of finance during the past quarter century has been the theory of capital structure the geneses of this controversy were the seminal contributions by modigliani and miller 18 19 the general academic view by the mid 1970s although not a consensus was that the optimal capital structure involves balancing the tax advantage of debt against the present value of bankruptcy costs no sooner did this general view become prevalent in the profession than miller 16 presented a new challenge by showing that under certain conditions the tax advantage of debt financing at the firm level is exactly offset by the tax disadvantage of debt at the personal level since then there has developed a burgeoning theoretical literature attempting to reconcile miller s model with the balancing theory of optimal capital structure e g deangelo and masulis 5 kim 12 and modigliani 17 the general result of this work is that if there are significant leverage related costs such as bankruptcy costs agency costs of debt and loss of non debt tax shields and if the income from equity is untaxed then the marginal bondholder s tax rate will be less than the corporate rate and there will be a positive net tax advantage to corporate debt financing the firm s optimal capital structure will involve the trade off between the tax advantage of debt and various leverage related costs the upshot of these extensions of miller s model is the recognition that the existence of an optimal capital structure is essentially an empirical issue as to whether or not the various leverage related costs are economically significant enough to influence the costs of corporate borrowing the miller model and its theoretical extensions have inspired several timeseries studies which provide evidence on the existence of leverage related costs trczinka 28 reports that from examining differences in average yields between taxable corporate bonds and tax exempt municipal bonds one cannot reject the miller hypothesis that the marginal bondholder s tax rate is not different from the corporate tax rate however trczinka is careful to point out that this finding does not necessarily imply that there is no tax advantage of corporate debt if the personal tax rate on equity is positive indeed buser and hess 1 using a longer time series of data and more sophisticated econometric techniques estimate that the average effective personal tax rate on equity is statistically positive and is not of a trivial magnitude more importantly they document evidence that is consistent with the existence of significant leverage related costs in the economy

social ties within school classes the roles of gender ethnicity and having older siblings in this paper we identify the lines along which social ties between high school teenagers are primarily formed to this end we introduce interaction weights between pupils in the same school class that are a function of exogenous individual background characteristics such as gender ethnicity and having older siblings the resulting model with endogenous interactions and school specific fixed effects is estimated using data from the dutch national school youth survey nsys a survey in which in principle all pupils in a sampled class are interviewed by combining the 1992 1996 1999 and 2001 nsys data we are able to identify trends in social relationships of teenagers we find that the roles that gender and ethnicity play in how teenagers interact varies strongly across different types of behaviour for example going out shows strong within ethnicity interactions while expenditures on cell phones and on clothing exhibit mainly between girls interactions having older siblings has a minor effect on within school class social interactions there is weak evidence of decreased ethnic segregation within school classes during the decade considered

competitive equilibria in production economies with an infinite dimensional commodity space the existence of competitive equilibrium is established for economies with a produc tion sector and an infinite dimensional space of commodities the cru cial assumptions which are required beyond those required in the fin ite dimensional setting are bounds on marginal rates of substitution and marginal rates of transformation copyright 1987 by the econometric society

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

target behavior and financing how conclusive is the evidence the notion that firms have a debt ratio target that is a primary determinant of financing behavior is influential in finance yet how definitive is the evidence we address this issue by generating samples where financing is unrelated to a firm s current debt ratio or a target we find that much of the available evidence in favor of target behavior based on leverage ratio changes can be reproduced for these samples taken together our findings suggest that a number of existing tests of target behavior have no power to reject alternatives

testing theories of capital structure and estimating the speed of adjustment this paper examines time series patterns of external financing decisions and shows that publicly traded u s firms fund a much larger proportion of their financing deficit with external equity when the cost of equity capital is low the historical values of the cost of equity capital have long lasting effects on firms capital structures through their influence on firms historical financing decisions we also introduce a new econometric technique to deal with biases in estimates of the speed of adjustment toward target leverage we find that firms adjust toward target leverage at a moderate speed with a half life of 3 7 years for book leverage even after controlling for the traditional determinants of capital structure and firm fixed effects

the role of target leverage in security issues and repurchases the paper examines whether security issues and repurchases adjust the capital structure toward the target the time series patterns of debt ratios imply that only debt reductions are initiated to offset the accumulated deviation from target leverage the importance of target leverage in earlier debt equity choice studies is driven by the subsample of equity issues accompanied by debt reductions unlike debt issues and reductions equity issues and repurchases have no significant lasting effect on capital structure therefore even firms that have target debt ratios can engage in timing the equity market

risks and financing decisions in the energy sector an empirical investigation using firm level data using a sample of 102 uk energy firms over the period 1981 2009 this paper empirically examines the effects of uncertainty on firms leverage decisions the results indicate that both firms specific and macroeconomic uncertainty have negative sizeable and statistically significant impacts on the uk energy sector firms target leverage the results also indicate that the profitability of energy firms plays an important role in uncertainty leverage relationship by changing the total effect of uncertainty on leverage while more profitable firms appear to reduce their leverage by a relatively large amount in response to increased macroeconomic uncertainty they are less likely to be affected by firm specific uncertainty these results suggest that stability in macroeconomic conditions and business activity is important to the stability of the capital structure of firms in the energy sector which would in turn be conducive to stability in their investments and production

on the existence of price equilibria in dynamic economies abstract i extend mckenzie s general characterization of the existence of competitive equilibria in static finite horizon models to a class of dynamic infinite horizon economies that subsumes overlapping generations as a special case with a few necessary exceptions the assumptions employed in my existence proof are natural extensions of mckenzie s in particular i strengthen the existing literature by imposing mckenzie type irreducibility only on the whole economy and not on certain artificial sub economies and by imposing mckenzie s weak continuity and convexity conditions i also establish the general existence of equilibria with nominal government surplus

edgeworth equilibria in production economies abstract an edgeworth equilibrium is an allocation that belongs to the core of every n fold replica of the economy in this work we study the properties of edgeworth equilibria for economies with production and infinite dimensional commodity spaces under some relatively mild conditions we establish among other things that 1 edgeworth equilibria exist 2 every edgeworth equilibrium is a quasi equilibrium and 3 an allocation is an edgeworth equilibrium if and only if it can be decentralized by a price system

taxes and capital structure evidence from firms response to the tax reform act of 1986 while the theoretical relation between taxes and capital structure has been extensively analyzed the empirical evidence on this issue has thus far been inconclusive one of the main difficulties confronting previous empirical studies of the cross sectional relationship between taxes and leverage was the control of intervening variables the tax reform act of 1986 tra which drastically changed the tax regime provides a unique opportunity to assess the interaction between taxes and leverage decisions in a controlled environment the authors test the relationship between leverage and certain tax related variables for a large sample of companies in the years surrounding the enactment of tra the results support the tax based theories of capital structure the findings indicate that there exists a substitution effect between debt and nondebt tax shields and that both corporate and personal tax rates affect leverage decisions coauthors are dan givoly aharon r ofer and oded sarig article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

proxies for the corporate marginal tax rate abstract this paper focuses on how best to measure the corporate marginal tax rate which is an important input into financial analysis of the cost of capital financing policy corporate hedging and corporate reorganizations the results indicate that the simulated tax rate used by shevlin 1990 and graham 1996 although difficult to calculate is the best available proxy for the true marginal tax rate if the simulated rate is unavailable an easy to calculate trichotomous variable or the statutory marginal tax rate which captures the progressivity in the tax schedule are reasonable alternatives better than most commonly used tax variables

corporate behavior in adjusting to capital structure and dividend targets an econometric study this study of financing decisions by u s corporations examines the issuance of long term debt issuance of short term debt maintenance of corporate liquidity issuance of new equity and payment of dividends given costs and imperfections inherent in markets a firm s financial behavior is characterized as partial adjustment to long run financial targets individual firm data are used so that speeds of adjustment are allowed to vary by company and over time the results suggest that financial decisions are interdependent and that firm size interest rate conditions and stock price levels affect speeds of adjustment this study of financing decisions by u s corporations examines the issuance of long term debt short term debt and equity the maintenance of corporate liquidity and the payment of dividends the firm s financial behavior is characterized as partial adjustment to long run financial targets and individual firm data 1966 1978 are used to estimate firm specific time varying speeds of adjustment the results suggest that financial decisions are interdependent and that firm size interest rate conditions and stock price levels affect speeds of adjustment also the estimated coefficients are more plausible than the very small taggart 28 or very large spies 26 values found in earlier studies section i of the paper introduces the general model in section ii a tractable empirical model is developed section iii presents the data to be used in the study and discusses econometric issues in section iv results and conclusions are offered

taxes and firm size abstract firm size has been used as a proxy for the firm s political costs and hence managers proclivity to choose income reducing accounting procedures this study provides additional evidence on this topic by examining the association between firm size and effective corporate tax rates the latter are one component of a firm s political costs the roughly fifty largest u s exchange listed firms in particular oil and gas companies and manufacturing firms have significantly higher worldwide tax rates than other firms these higher tax rates are observed primarily after the implementation of the u s 1969 tax reform act and after the opec countries raised their tax rates on u s oil producers the findings which are insensitive to alternative sources of data alternative measures of firm size and alternative measures of effective tax rates are consistent with the use in previous studies of firm size as a proxy for the firm s political costs

mechanical mean reversion of leverage ratios abstract the leverage ratio of an average firm reverts to mean mechanically regardless of whether target leverage exists this cautions against studies that use the ability of the leverage ratio or deviation from target leverage to predict future leverage changes to draw inference on capital structure theories

differential tax benefits and the pension reversion decision abstract we document that tax considerations influence whether and when a firm withdraws excess assets in its defined benefit pension plan through a reversion since a reversion impacts taxable income over many years and alternative methods of withdrawing excess assets exist we argue that the economically relevant tax based decision criterion is its differential tax benefit defined as the difference between the discounted tax savings of reversion versus those of the best alternative withdrawal method we develop a technique for directly estimating this decision criterion and document that differential tax benefits are strongly correlated with the reversion decision and its timing

the recursive core core allocations may be defined for infinite horizon capital accumulation models if agents cannot trust each other in the sense of gale then agents may renege on their commitments their decisions appear time inconsistent a core allocation is a recursive core allocation provided no coalition can improve upon its consumption stream at any time given its accumulation of assets up to that period we show for every allocation of consumption in the initial core one can find a distribution of capital stocks among the agents where no coalition of agents will break the initial core contract at any date it follows that if the proper distribution of the streams of capital is achieved then the allocation in the core is also in the recursive core the latter therefore forges a link between the distribution of wealth capital the problem of trust and time consistent intertemporal contracts

do firms undertake self tender offers to optimize capital structure this study investigates capital structure around 286 self tender offers from 1980 to 1997 firms that undertake self tender offers generally have debt ratios below their predicted levels before the offers the debt ratios following nondefensive self tender offers are close to predicted levels while the ratios following defensive self tender offers are above predicted levels further 20 and 43 of the debt ratings are downgraded following nondefensive and defensive self tender offers respectively finally the increases in debt ratios around the offers are negatively related to the difference from the predicted debt ratio before the offers

debt and seniority an analysis of the role of hard claims in constraining management we argue that long term debt has a role in controlling management s ability to finance future investments a company with high widely held debt will find it hard to raise capital since new security holders will have low priority relative to existing creditors conversely for a company with low debt we show there is an optimal debt equity ratio and mix of senior and junior debt if management undertakes unprofitable as well as profitable investments we derive conditions under which equity and a single class of senior long term debt work as well as more complex contracts for controlling investment behavior

incorporating active adjustment into a financing based model of capital structure abstract the conventional partial adjustment model which focuses on leverage evolution has difficulty identifying deliberate capital structure adjustments as it confounds financing decisions with the mechanical autocorrelation of leverage we propose and estimate a financing based partial adjustment model that separates the effects of financing decisions on leverage evolution from mechanical evolution the speed of adjustment soa is firm specific and stochastic and active targeting of capital structure has a multiplier effect that depends on the size of financial deficit overall we find expected soa from active rebalancing 30 more than doubles what is expected from mechanical mean reversion alone 13
